GLOSSARY OF TERMS

We report our reserves to two separate standards to meet the requirements for reporting in both the United States (“U.S.”) and Canada.  U.S. reporting requirements for disclosure of mineral properties are governed by Securities and Exchange Commission Industry Guide 7.  Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 (“NI 43-101”).  The definitions given in NI 43-101 are adopted from those given by the Canadian Institute of Mining Metallurgy and Petroleum.

The definitions for each reporting standard are presented below with supplementary explanation and descriptions of the parallels and differences.

1

SEC INDUSTRY GUIDE 7 DEFINITIONS

mineralized material⁽¹⁾

The term “mineralized material” refers to material that is not included in the reserve as it does not meet all of the criteria for adequate demonstration for economic or legal extraction.

non-reserves

The term “non-reserves” refers to mineralized material that is not included in the reserve as it does not meet all of the criteria for adequate demonstration for economic or legal extraction.

exploration stage

An “exploration stage” prospect is one which is not in either the development or production stage.  

development stage

A “development stage” project is one which is undergoing preparation of an established commercially mineable deposit for its extraction but which is not yet in production.  This stage occurs after completion of a feasibility study.  

production stage

A “production stage” project is actively engaged in the process of extraction and beneficiation of mineral reserves to produce a marketable metal or mineral product.  

NI 43-101 DEFINITIONS

mineral resource

The term “mineral resource” refers to a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge.

measured mineral resource

The term “measured mineral resource” refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

indicated mineral resource

The term “indicated mineral resource” refers to that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable

2

exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

inferred mineral resource

The term “inferred mineral resource” refers to that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

qualified person⁽²⁾

The term “qualified person” refers to an individual who is an engineer or geoscientist with at least five years of experience in mineral exploration, mine development, production activities and project assessment, or any combination thereof, including experience relevant to the subject matter of the project or report and is a member in good standing of a self-regulating organization.

_______________________

(1)

This category is substantially equivalent to the combined categories of measured and indicated mineral resources specified in NI 43-101.

(2)

Industry Guide 7 does not require designation of a qualified person.

PART I

ITEM 1.

BUSINESS

General

Mines Management, Inc. (together with its subsidiaries, “MMI,” “Company” or “we”), is engaged in the business of acquiring and exploring, and if exploration is successful, developing mineral properties, primarily those containing silver and associated base and precious metals. The Company was incorporated under the laws of the State of Idaho on February 20, 1947.  The Company has a wholly owned subsidiary, Newhi, Inc.  The subsidiary was incorporated under the laws of the State of Washington on November 3, 1987.  The Company’s executive offices are located at 905 W. Riverside, Suite 311, Spokane, WA 99201.

The Company’s principal mineral property interest is held by its wholly owned subsidiary, Newhi, Inc., and is referred to as the Montanore Project.  The Montanore Project is located in northwestern Montana, and from 1988 to 2002 was owned by Noranda Minerals Corporation.  During that time the project received an approved environmental impact statement and all of its primary environmental permits.  From 1988 to 2002 the Company held royalty rights to a portion of the deposit.  In 2002 Noranda announced that it was abandoning the project, and subsequently transferred to the Company by quitclaim deed the patented and unpatented mining claims that control the mineral rights, and all core and intellectual property including geologic, environmental and engineering studies.

The Company’s properties, including the Montanore property, are currently in the exploration stage.  The Company has commenced re-permitting of the Montanore property and determining its feasibility for development. No property is currently in production.

The Company’s principal focus for 2006 continues to be to update Montanore environmental and engineering studies aimed at determining an economically viable operational design, and re-establish previously issued environmental and mining permits.

The Company continues to hold its Iroquois and Advance zinc-lead properties in Washington on a care and maintenance basis and plans to evaluate these properties in light of the current base metals market in the first half of 2006.  The Company also has a small royalty income from a working interest royalty, acquired more than 40 years ago, for several producing oil wells located in Kansas.

Competition

There is aggressive competition within the minerals industry to discover and acquire properties considered to have commercial potential.  The Company competes for the opportunity to participate in promising exploration projects with other entities, many of which have greater resources than the Company.  In addition, the Company competes with others in efforts to obtain financing to explore and develop mineral properties.

Employees

As of March, the Company had seven full-time employees located in Spokane, Washington. The Company’s employees are not subject to a union labor contract or collective bargaining agreement. Outside consultants are engaged to perform project and permitting tasks that will be used in re-permitting the Montanore Project.  The Company expects to continue to rely on the use of outside services in the immediate future.

6

Regulation

The Company’s activities in the United States are subject to various federal, state, and local laws and regulations governing exploration, labor standards, occupational health and mine safety, control of toxic substances, and other matters involving environmental protection and taxation.  In addition, it is possible that future changes in these laws or regulations could have a significant impact on the Company’s business, causing those activities to be economically reevaluated at that time.

ITEM 1A.

RISK FACTORS

Our business, operations, and financial condition are subject to various risks.  We urge you to consider the following risk factors in addition to the other information contained in, or incorporated by reference into, this Report on Form 10-K.

We have no recent history of production.

We have no recent history of producing silver or other metals.  The development of our Montanore Project will require the construction and operation of mines, processing plants, and related infrastructure.  As a result, we are subject to all of the risks associated with establishing a new mining operation and business enterprise.  There can be no assurance that we will successfully establish mining operations or profitability.

We have a history of losses and we expect losses to continue for at least the next three years.

As an exploration and development company that has no production history, we have incurred losses since our inception and we expect to continue to incur additional losses for at least the next three years.  As of December 31, 2005, we had an accumulated deficit of $9.2 million.  There can be no assurance that we will achieve or sustain profitability in the future.

We have no proven or probable reserves.

We have no proven or probable reserves on any of our properties.  We are currently focused on our Montanore Project.  Substantial additional work, including delineation drilling, will be required in order to determine if any proven or probable reserves exist on our Montanore Project.  The commercial viability of a mineral deposit once discovered is also dependent on a number of factors beyond our control, including particular attributes of the deposit such as size, grade and proximity to infrastructure, as well as metal prices.  In the event commercial quantities of minerals are discovered, the Montanore Project might not be brought into commercial production.

The exploration of mineral properties is highly speculative in nature, involves substantial expenditures and is frequently non-productive.

Mineral exploration is highly speculative in nature and is frequently non-productive. Substantial expenditures are required to:

·

establish ore reserves through drilling and metallurgical and other testing techniques;

·

determine metal content and metallurgical recovery processes to extract metal from the ore; and

·

design and construct mining and processing facilities.

If we discover ore, it usually takes several years from the initial phases of exploration until production is possible. During this time, the economic feasibility of production may change. As a result of these uncertainties, there can be no assurance that we will successfully acquire additional mineral rights,

7

or that our exploration programs will result in new proven and probable reserves in sufficient quantities to justify commercial operations in any of our properties.

Our future success is subject to risks inherent in the mining industry.

Our future mining operations, if any, will be subject to all of the hazards and risks normally incident to developing and operating mining properties.  These risks include insufficient ore reserves, fluctuations in metal prices and in production costs that may make mining of reserves uneconomic; significant environmental and other regulatory restrictions; labor disputes; geological problems; failure of underground stopes and/or surface dams; force majeure events; and the risk of injury to persons, property or the environment.

Our future profitability will be affected by changes in the prices of metals.

If we establish reserves and complete a favorable feasibility study for the Montanore Project, our profitability and long-term viability depend, in large part, on the market price of silver and copper.  The market prices for these metals are volatile and are affected by numerous factors beyond our control, including:

·

global or regional consumption patterns;

·

supply of, and demand for, silver and copper;

·

speculative activities;

·

expectations for inflation; and

·

political and economic conditions.

The aggregate effect of these factors on metals prices is impossible for us to predict. Decreases in metals prices have delayed, and could in the future adversely affect our ability to finance, the exploration and development of our properties, which would have a material adverse effect on our financial condition and results of operations and cash flows. There can be no assurance that metals prices will not decline.  During the five-year period ended December 31, 2005, the high and low settlement prices for silver and copper were $9.23 and $4.07 per ounce and $2.28 and $0.66 per ounce, respectively.

We may not be able to obtain permits required for development of the Montanore Project.

In the ordinary course of business, mining companies are required to seek governmental permits for expansion of existing operations or for the commencement of new operations. We will be required to reactivate numerous permits for our Montanore Project. Obtaining the necessary governmental permits is a complex and time-consuming process involving numerous jurisdictions and often involving public hearings and costly undertakings. Obtaining required permits for Montanore Project may be more difficult due to its location within the Cabinet Wilderness Area.  The duration and success of our efforts to re-permit are contingent upon many variables not within our control. Obtaining environmental protection permits, including the approval of reclamation plans, may increase costs and cause delays depending on the nature of the activity to be permitted and the interpretation of applicable requirements implemented by the permitting authority.  There can be no assurance that all necessary permits will be obtained and, if obtained, that the costs involved will not exceed those that had been previously estimated.  It is possible that the costs and delays associated with the compliance with such standards and regulations could become such that we would not proceed with the development or operation of a mine or mines.

8

Changes in mining laws could increase costs and impair our ability to develop its properties.

From time to time the U.S. Congress may consider revisions in its mining and environmental laws. It remains unclear to what extent new legislation may affect existing mining claims or operations.  The effect of any such revisions on our operations cannot be determined conclusively until such revision is enacted; however, such legislation could materially increase costs on properties located on federal lands, and such revision could also impair our ability to develop its mineral projects.

We are subject to environmental risks.

Mining is subject to potential risks and liabilities associated with pollution of the environment and the disposal of waste products occurring as a result of mineral exploration and production.  Insurance against environmental risk (including potential liability for pollution or other hazards as a result of the disposal of waste products occurring from exploration and production) is not generally available to us (or to other companies in the minerals industry) at a reasonable price.  To the extent that we become subject to environmental liabilities, the satisfaction of those liabilities would reduce funds otherwise available to us and could have a material adverse effect on us.  Laws and regulations intended to ensure the protection of the environment are constantly changing, and are generally becoming more restrictive.

The title to some of our properties may be uncertain or defective.

Although the Montanore deposit is held by patented mining claims, a significant portion of our holdings consist of unpatented lode and mill site claims.  Certain of our United States mineral rights consist of “unpatented” mining claims created and maintained in accordance with the U.S. General Mining Law of 1872.  Unpatented mining claims are unique U.S. property interests, and are generally considered to be subject to greater title risk than other real property interests because the validity of unpatented mining claims is often uncertain.  This uncertainty arises, in part, out of the complex federal and state laws and regulations that supplement the General Mining Law.  Also, unpatented mining claims and related rights, including rights to use the surface, are subject to possible challenges by third parties or contests by the federal government.  The validity of an unpatented mining claim, in terms of both its location and its maintenance, is dependent on strict compliance with a complex body of federal and state statutory and decisional law.  In addition, there are few public records that definitively control the issues of validity and ownership of unpatented mining claims.  We have not filed a patent application for any of the unpatented claims that are located on federal public lands in the United States and, under possible future legislation to change the General Mining Law, patents may be difficult to obtain.

In recent years, the U.S. Congress has considered a number of proposed amendments to the General Mining Law.  Although no such legislation has been adopted to date, there can be no assurance that such legislation will not be adopted in the future.  If ever adopted, such legislation could, among other things, impose royalties on silver and copper production from unpatented mining claims located on federal lands or impose fees on production from patented mining claims.  Further, it could have an adverse impact on earnings from our operation, could reduce estimates of our reserves and could curtail our future exploration and development activity on federal lands or patented claims.

While we have no reason to believe that title to any of our properties is in doubt, title to mining properties is subject to potential claims by third parties claiming an interest in them.

The market price of our common shares could experience volatility and could decline significantly.

Our common shares are listed on American Stock Exchange (AMEX) and the Toronto Stock Exchange (TSX.)  Securities of small-cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved.  These factors include macroeconomic developments in North America and globally and market

9

perceptions of the attractiveness of particular industries.  Our share price is also likely to be significantly affected by short-term changes in silver and copper prices or in our financial condition or results of operations as reflected in our quarterly earnings reports.  Other factors unrelated to our performance that could have an effect on the price of our common shares include the following:

·

the extent of analytical coverage available to investors concerning our business is limited because investment banks with research capabilities do not follow our securities;

·

the trading volume and general market interest in our securities could affect an investor’s ability to trade significant numbers of common shares;

·

the relatively small size of the public float will limit the ability of some institutions to invest in our securities; and

·

a substantial decline in our stock price that persists for a significant period of time could cause our securities to be delisted from the AMEX and the TSX, further reducing market liquidity.

As a result of any of these factors, the market price of our common shares at any given point in time might not accurately reflect our long-term value.  Securities class action litigation often has been brought against companies following periods of volatility in the market price of their securities.  We could in the future be the target of similar litigation. Securities litigation could result in substantial costs and damages and divert management’s attention and resources.

ITEM 2.

DESCRIPTION OF PROPERTIES

The significant properties in which the Company has an interest are described below.

Montanore Property

The Montanore Project is located in Sanders and Lincoln Counties in northwestern Montana and consists of two federal patented mining claims and approximately 776 unpatented lode mining claims and mill sites, which cover approximately 1700 acres.  The unpatented lode claims and mill sites are owned by the Company and are held subject to a $125 per claim annual payment to the Federal Government.

The Company’s ownership of the Montanore deposit stems primarily from its ownership of 2 patented mining claims, identified as HR 133 and HR 134, which cover the surface outcrop or “apex” of the gently dipping mineralized beds.  According to US mining law, the holders of claims covering the apex of a dipping, tabular deposit own the minerals to depth, even if the deposit passes from beneath the apex claim.  For the Company’s claims at Montanore these “extralateral rights” have been confirmed by the US Secretaries of Agriculture and Interior and upheld in US District Court.  In addition to the patented apex claims, the Company owns unpatented claims located along the fault which bounds the southwestern margin of the deposit, and which extend outside of the western border of the Cabinet Wilderness Area.

The Montanore Project deposit can be reached from Noxon, the nearest town, by taking State Highway 200 about 2 miles to the east and then north about 5 miles on a secondary graveled road to the junction of the west and east forks of Rock Creek.  From this point it is about a 4 mile hike up a Jeep trail behind a locked U.S. Forest Service gate to the deposit outcrop.  The deposit outcrops near the border of, and lies entirely within the Cabinet Wilderness Area.  Because any future mining of the deposit would take place underground and the Company has access to the deposit from outside the Cabinet Wilderness Area, (our patented mining claims and certain other mineral rights predate the wilderness area designation), we do not believe that any future mining or associated surface activity would impact the wilderness area.  The Company’s holdings for operational access and infrastructure support for the project are located to the east, south of the town of Libby, and are accessed from that major supply point by about 16 miles of secondary road up Libby Creek. There is no plant, equipment, subsurface improvements or

10

equipment other than a 14,000-foot adit, which was plugged and graded by Noranda and is currently in reclamation.  The Company expects to obtain power by extending a Flathead Electric power line from Noxon, Montana, located approximately 18 miles from the Montanore property.  The Company owns water rights associated with the Montanore property which it believes will be sufficient for possible mining activities.

Non-Reserves – Mineralized Material; Measured, Indicated and Inferred Resources

The estimate of mineralized material set forth below was prepared by Mine Development Associates.  The estimate was prepared in accordance with SEC Industry Guide 7 based on silver and copper prices of $6.24 per ounce and $1.26 per pound, respectively, which represent the three year rolling average prices at December 31, 2005.  

Mineralized Material Estimate in Accordance with U.S. SEC Industry Guide 7

	Tons	Silver Grade (Ounces per ton)	Copper Grade	Cutoff (Silver ounces per ton)
Mineralized Material	81,506,000	2.04	0.75%	1.0

In accordance with Canadian National Instrument 43-101, MDA has estimated the resource at Montanore as set forth below.  Steve Ristorcelli, R.P. Geo., C.P.G. and David C. Fitch, C.P.G., are the qualified persons under Canadian National Instrument 43-101 for this resource estimate.

Cautionary Note to US Investors concerning estimates of Measured and Indicated Mineral Resources

This section uses the terms "measured mineral resources" and "indicated mineral resources". We advise US investors that while those terms are recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize them, and describes the equivalent as "Mineralized Material". US Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves.

Cautionary Note to US Investors concerning estimates of Inferred Mineral Resources

This section uses the term "inferred mineral resources." We advise US investors that while this term is recognized and required by Canadian regulations, the US Securities and Exchange Commission does not recognize it. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. In accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. US investors are cautioned not to assume that part or all of the inferred mineral resource exists, or is economically or legally mineable.

Resource Estimate in Accordance with Canadian National Instrument 43-101

	Tons	Silver Grade (Ounces per ton)	Copper Grade	Cutoff (Silver ounces per ton)
Measured	4,026,000	1.85	0.74%	1.0
Indicated	77,480,000	2.05	0.75%	1.0
Inferred	35,080,000	1.85	0.71%	1.0

Geology

The Montanore deposit occurs within Revett Formation quartzite of the Belt Super Group, Precambrian sedimentary rock that crop out over much of western Montana, northern Idaho, and parts of adjacent British Columbia.

The Montanore deposit has been defined as being at least 12,500 feet long and varies between 500 and 4,000 feet in width.  The long axis of the deposit trends in a northwesterly direction parallel with a regional fault that bounds the mineralization on the southwest.  The deposit dips approximately 12 degrees to the northwest, parallel with its long axis.  Mineralization occurs within two mineralized beds over much of the deposit’s length.  Overall the upper zone averages 29.9 feet in thickness and the lower zone 34.8 feet.  Unmineralized strata between beds varies between 20 and 200 feet thick.  The deposit remains open to the northwest within the Company’s extra-lateral rights.

History

In 1983, U.S. Borax and Chemical Corporation discovered the Montanore silver/copper deposit, which extended in part beneath what is now the Company’s property.  In 1984 a lease for 11 claims was entered into between U.S. Borax and our predecessor, Heidelberg Silver Mining Co., Inc.  U.S. Borax conducted more than 70,000 feet of core drilling from the surface, which outlined the bedded silver/copper mineralization.  In 1988, U.S. Borax and partners sold their interest in the project to a joint venture between Noranda Minerals Corp. and Montana Reserves Co.

Also in 1988, Newhi, Inc., our wholly owned subsidiary, acquired the assets of Heidelberg through a corporate merger.  The assets acquired by Newhi consisted primarily of 34 unpatented mining claims located along the fault that borders the Montanore deposit, and a 4 acre patented mill site.  In 1993, we determined that 18 of the mining claims were immaterial to the maintenance of our interest in the Montanore project and these claims were dropped.  Of the remaining 16 claims, 11 claims were leased to Noranda for an annual payment of $25,000 and a net profits interest.

In late 1989, Noranda began construction of an adit using a conventional tunneling method from a point east of the Cabinet Wilderness Area. The purpose of the program was to more accurately define and develop a portion of the deposit containing approximately 30 million tons.  The proposed work was to include a 3-mile long decline and approximately 2,000 feet of lateral development in the vicinity of the deposit.  Close spaced drilling was planned from these workings and bulk metallurgical samples were to be taken during this phase.  In December 1991, tunneling was stopped at approximately 14,000 feet, or about 2,000 feet short of the deposit, pending the completion of the project’s environmental impact statement (EIS).  Also during the year Noranda completed the process to acquire patents to the two “apex” claims controlling the deposit.  In 1993, the joint venture between Noranda and Montana Reserves was dissolved with Noranda retaining rights to the project.

During 1993, the Montanore EIS was approved and all of the important permits for the mine were granted.  As part of the EIS process, this approval was subject to appeal, and several appeals were made.  In 1994, the US Forest Service denied all appeals.  In 1991, an environmental group brought suit against Noranda and the US Forest Service concerning the validation of Noranda’s apex claims.  In 1993, the US Secretary of Agriculture found that Noranda’s mining claims were valid, and in 1997 the US District Court hearing the case also ruled that Noranda’s claims were valid.  The court decision was appealed and in March, 1999 the U.S. Court of Appeals for the Ninth Circuit upheld the U.S. District Court decision.  In 2001 the U.S. government issued patents for the two claims covering the apex of the deposit and thus assuring Noranda ownership of the Montanore deposit.

12

In 2002, Noranda notified us that it was abandoning its rights to the project.  Under terms of its agreement, Noranda was bound to quitclaim to us any claims that overlapped the original Heidelberg claims.  As the newly patented apex claims were overlapping, Noranda deeded these claims to Newhi in August 2002.  The mineral rights we acquired are subject to a $0.20 per ton royalty, and a 5% net profits royalty which would commence after the operator has recovered all of its exploration and development costs.  In December 2002, Noranda transferred to us 70,000 feet of drill core and all geologic, environmental, and engineering data generated during its 14 year management of the project.

The Company resubmitted its plan of operation and hard rock mine operating permit application for the Montanore project to the U.S. Forest Service (USFS) and Montana Department of Environmental Quality (MDEQ) at the end of December 2004.  The application represents the identical project on public land that each agency reviewed and approved for Noranda in 1993.

The Montanore property is undergoing an extensive optimization review and feasibility study in order to update the mine plan and to determine the optimal rates of production.  We have spent an estimated $4.2 million on the Montanore property since acquiring it, primarily on the re-permitting process and a pre-feasibility study, and an additional $50,000 per year in property holding costs. We estimate expenditures of at least $4.0 million in 2006 in connection with the continued permitting, engineering, and exploration.

Engineering

McIntosh Engineering and Hatch Ltd. continue work on project engineering, including optimization, trade-off, design revisions, and other key evaluations for the Montanore project.  The engineering effort has advanced mine planning, mine and mill designs, operational criteria, and other key aspects of project planning and cost estimates.  Preliminary mine plans and costs were completed late in the fourth quarter of 2005.  We are currently completing an internal review and are working with McIntosh and Hatch to finalize the report and refine the plans and designs.  This detailed engineering work by McIntosh and Hatch is expected to be completed in the second quarter of 2006.  The results from these studies will provide the direction and planning necessary to move to the next stage of project development.

Mine planning information developed by McIntosh during this stage of the engineering evaluation used Vulcan mine planning software.  Mines Management has purchased the software and is initiating advancement of the McIntosh mine plan design in the first quarter of 2006.  In addition, this computer model will assist in developing a preliminary underground drilling program to be implemented when access to the Libby adit is obtained.

Smelting

Mines Management has initiated discussions with smelters and expects discussions to continue as part of the detailed design and engineering cost efforts throughout 2006.  This information will be important in mine planning and operational cost considerations for the project.  Defining smelting costs and terms are considered in the economic parameters for grade cut-off considerations in the mine plan.

Permitting and Environmental

During 2005, we continued to advance the permitting and optimization review of the Montanore project.  The U.S. Forest Service (the “USFS”) and the Montana Department of Environmental Quality (the “Montana DEQ”) have been actively engaged in reviewing company reports and applications.  During August 2005 public scoping meetings were held in Libby and Trout Creek, Montana, and Bonners Ferry, Idaho, out of which limited comments were received concerning the Montanore project.  All comments were documented by the USFS and Montana DEQ and will be addressed in the final EIS.  The

13

public comment period for the Montanore Project closed in September 2005.  The U.S. Forest Service and Montana DEQ have compiled a list of comments and issues that will be incorporated into the EIS.  ERO, a Denver based EIS contractor, was retained and initiated a review of the transmission line and mine water permit applications in an effort to assist agency staff in the review process.  We and our consultants are working with the agencies and the EIS contractors to address design and operational plans as part of the overall permitting process.

We have initiated field work and technical efforts focused on fisheries habitat evaluation, fisheries population, wildlife, vegetation, threatened and endangered species, visual assessments, and other key environmental elements.  At the request of the MDEQ the Company recently completed a water sampling program for the neighboring wilderness lakes to establish current lake and stream baseline conditions.  This information was used to support a regional and local hydrologic report update for the project area.

We submitted the 230 kv power transmission line permit application during the second quarter of 2005.  Montana DEQ/ERO has reviewed the initial permit transmission line application and has provided comments to us.  We are actively working on providing supplemental information to support the transmission line application.  We expect to submit the supplemental transmission line application in the first half of 2006.

A Montana Pollution Discharge Elimination System draft application was submitted to the Montana DEQ in the third quarter 2005.  Preliminary comments from the agency were received and a final permit application was submitted in the fourth quarter 2005.  This permit application is necessary for the project and will authorize the proposed management of water during operations.

Montana permitting regulations require the Company to submit a Hard Rock Mine Impact Analysis to local forms of government.  This report assesses potential economic benefits and impacts to local government services.  Mines Management submitted and presented this Impact Analysis to the Lincoln County and City of Libby governmental officials, who are currently reviewing it.  Once the Analysis and report are approved, the document will be submitted to the State for review and referred to the Hard Rock Mining Impact Board for approval.

In the third quarter of 2005 the Company held consultation meetings with local tribal organizations which included a site visit to Montanore.  This is the first of several steps required in the approval process.

Advance and Iroquois Properties

The Company owns the Advance and Iroquois zinc-lead exploration properties located in northeastern Washington State, approximately 6 miles south of the Canadian border.  The properties are situated 5 miles apart along a belt of Cambrian carbonate sediments that have acted as host rocks for several former mines.  Both properties are easily accessible on secondary graveled roads by two wheel drive vehicles.  A large zinc smelter and refinery is located at Trail, British Columbia, Canada, approximately 17 miles distance, over excellent roads.

The Company was originally formed in 1947 to explore the Advance and Iroquois properties.  Since that time, Mines Management has leased its holdings to major companies including: Rare Metals, Inc. (El Paso Natural Gas) (1959-65), The Bunker Hill Company (1962-65), Cominco American, Inc. (1966-67 and 1974-75), Brinco, Ltd. (RTZ Group) (1977-78), and Equinox Resources Ltd.  (1989-91). Total expenditures on the properties to date are estimated to be at least $1,500,000.

The Advance and Iroquois properties are located along the Deep Lake Trend, a northeast-striking belt of Cambrian carbonate rocks collectively designated as the Metaline Limestone.  Rocks of the Deep Lake Trend have been strongly folded and faulted by numerous high-angle as well as thrust faults.  As a result the Metaline Limestone has a complex outcrop pattern, with steeply overturned bedding.

Zones of brecciation are found throughout the Metaline Limestone and are often, but not always, the location of zinc and lead sulfide mineralization.  These features are predominantly stratabound and have gradational, often irregular borders.  Individual breccia bodies are crudely lensoid in cross section and have third dimensions that attain considerable length.  The zones often occur in an enechelon, and sometimes interconnected, pattern.  A variety of evidence suggests that the breccia bodies are solution collapse features controlled by favorable stratigraphy or lithologic facies.

Mineralization consists of irregular bands, lenses, and fine disseminations of sphalerite and galena accompanied by varying amounts of pyrite.  The mineralization is considered to have been localized by permeable zones within and peripheral to breccia bodies created by solution collapse. The sulfide minerals are found in white dolomite that makes up the breccia matrix and fills other voids, and also as selective replacements of the host carbonate rocks.  Individual deposits have irregular gradational borders and are crudely lensoidal to oval in outline. Their elongated third dimension parallels the regional strike of the host rocks, and often plunge at low angles.  Cross sectional widths up to 80 feet and heights of as much as 150 feet have been noted in the more prominent zones.  Lengths of mineralization vary up to 650 feet.  The deposits have a tendency to occur together in an enechelon pattern over a stratigraphic interval of as much as 300 feet.  Such groupings of deposits may be more or less interconnected and have composite lengths of as much as 5000 feet.  Metal values generally decrease outward thus necessitating a border to be established by economic consideration.  Although individual sample values within a deposit may be as high as 20% zinc, average values for a deposit will usually range up to 7% zinc and 1% lead depending upon the “assay border” selected.

The Advance property consists of 720 acres of patented mineral rights, located approximately 5 miles east of the town of Northport.  The property is reached from Northport, the nearest town, by taking the paved Deep Lake road south for 4 miles to the graveled Black Canyon road and thence north for 3 miles. The Metaline Formation is the principal rock unit to crop out on the Advance property.  Exploration consisting of soil sampling, drilling, trenching, and tunneling has shown that several zones of low-grade, disseminated zinc mineralization occur on the property.  The Advance property is without known reserves, is considered to be of an exploratory nature, and is held by the Company on a maintenance basis.

16

The Iroquois property consists of 62 acres of patented mineral and surface rights, and 15 unpatented mining claims containing about 300 acres.  The property is reached from Northport, the nearest town, by taking the paved Deep Lake road south and east for 19 miles to the graveled road marked Iroquois Mine Road, and thence northeast for three miles.  The unpatented mining claims are held subject to a $100 per claim annual payment to the Federal government.  More than 25,000 feet of drilling and approximately 2,600 feet of tunneling have shown low-grade mineralization to occur in multiple zones, extending for the entire 5,000 foot length of the property.  Most of the exploration has been concentrated in one area where a mineralized zone of disseminated zinc with associated lead values has been outlined over approximately 900 feet in length and within 300 feet of the surface.  The Iroquois property is without known reserves, is considered to be of an exploratory nature and is held by the Company on a maintenance basis.

Oil Interests

The Company receives income from a 10.16% working interest in 4 oil wells on the Clark lease in Sumner County, Kansas.  Although the lease has now produced for more than 40 years, independent consultants calculated the Company’s 1981 share of the remaining reserves available through primary and secondary recovery to be at least 20,000 barrels.  Production since 1981 has totaled approximately 9600 barrels to the Company’s account.  The Company does not engage in oil and gas exploration or production activities.

ITEM 3.

LEGAL PROCEEDINGS

On August 11, 2005, Mines Management was named as a co-defendant in a lawsuit filed by Montana Reserves Company (“MRC”) in the Superior Court of the State of Washington in Spokane County, Washington. Named as co-defendants are Noranda Minerals, Normin Corp., Mines Management and Newhi, Inc. The action seeks damages in connection with the conveyance of the Montanore property from Noranda to Newhi, and challenges the computation of a net proceeds royalty payable to MRC pursuant to a Royalty Agreement between Noranda and MRC in respect of the Montanore property. Management does not believe that the outcome of this lawsuit will have a material adverse effect on the Company.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

The following Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand Mines Management, Inc.  The MD&A is provided as a supplement to, and should be read in conjunction with, our financial statements and the accompanying notes (“Notes”).

Overview

Management’s discussion and analysis (MD&A) for the year ending December 31, 2005 focuses on the significant progress made and other items that affected Mines Management’s performance and such factors that may affect its performance in the future.  The MD&A should be read in conjunction with the audited financial statements included in this Report on Form 10-K.  In 2006, the Company plans to focus on additional exploration and implementation of an underground drilling program at Montanore, as well as engineering and optimization studies.  The Company intends to continue its emphasis on the re-permitting applications and commencement of a phased financing plan for the Montanore project.

2005 Highlights

·

In 2005 submitted application to list on TSX, listed effective January 10, 2006

·

Maintained strong cash and investment position

·

Advanced the engineering cost studies for mining and milling operations

·

Continued re-permitting work with state and federal permitting agencies, including updating and collecting baseline data to support the agency review effort

·

Initiated the  preliminary Environmental Impact Statement (“EIS”) process

Financial and Operating Results

Mines Management, Inc. reported a net loss for the year ended December 31, 2005 of $5.2 million or $0.45 per share versus a loss of $2.5 million or $0.26 per share and $1.3 million or $0.18 per share for the years ending December 31, 2004 and 2003 respectively.  The 2005 increase in net loss versus 2004 of $2.7 million, and the 2004 net loss increase versus 2003 of $1.2 million, were primarily due to increased expenditures in the following major areas:

-

The major area for additional spending for 2005 over 2004 was the increased activity on the Montanore Project, primarily as a result of payments to consultants for permitting activities, collecting additional environmental baseline data, mineralized material and resource studies, and mine engineering and optimization.  Montanore project expense includes exploration, fees, filing and licenses, environmental, engineering and permitting expense.  Administrative expense, which includes general overhead and office expense, legal, accounting, compensation, rent, taxes, and investor relations expense, doubled in 2005 over 2004 as we commenced an investor relations program targeted at increasing liquidity, hired additional employees for the Montanore Project, and leased additional office space in January 2005 to accommodate our expanded staff.  Stock option expense, which includes stock options granted to officers, employees and consultants, decreased from 2004 to 2005 due to fewer options being granted and no previously issued options vesting in 2005.

The increased expenses in 2004 from 2003 were largely attributable to the start of our initial work on the Montanore Project.  The increase in administrative expense reflects primarily the addition of two executives, a full year of compensation for a new President and Chief Executive Officer, and a full year of severance payments to the previous President and Chief Executive Officer. The increase in stock option expense was due to the granting of options to executives hired in 2004 and the vesting of options granted in 2003 to the Company’s President and Chief Executive Officer, and issuance of employee and director non cash stock options.

Liquidity

At December 31, 2005, our aggregate cash, short term investments, and long term investments totaled $8.9 million compared to $6.5 million at December 31, 2004.  In 2005, we raised $6.1 million gross net proceeds in a private placement and $0.6 million from the exercise of warrants and exercise of stock options.  The net cash used for operating activities was $4.2 million, which consisted primarily of permitting, environmental and engineering expenses for the Montanore project and administrative expenses.  The net increase in cash and cash equivalents for the year ending December 31, 2005 was $2.2 million.

The Company anticipates spending approximately $1.0 million each quarter in 2006.  The Company has sufficient cash and cash equivalents to fund its 2006 expenditures.  

Off Balance Sheet Arrangements

We have no off balance sheet arrangements.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

All of our cash balances are held in U.S. dollars and our long term investment certificates of deposit are denominated in U.S. dollars and held in local and national banking institutions.  We manage the timing of cash required for the re-permitting, review of the Montanore deposit, and engineering of the Montanore project and for general corporate purposes by utilizing our money market account.  We invest funds not immediately required in investments, currently in certificates of deposit, with varying maturities and fixed early retirement costs equal to three months interest.  Our policy is to invest only in government and corporate grade securities rated “investment grade” or better.

The market prices of base and precious metals such as copper and silver fluctuate widely and are affected by numerous factors beyond the control of any mining company.  These factors include expectations with regard to the rate of inflation, the exchange rates of the dollar and other currencies, interest rates, global or regional political, economic or banking crises, and a number of other factors.  If the market price of silver or copper should drop dramatically, the value of the Company’s Montanore project could drop and the Company might not be able to recover its investment in that project.  The decision to develop or construct a mine would be made several years before the first revenues from production would be received.  Price fluctuations between the time that such decision is made and the commencement of production could affect the economics of the mine.

Notes to Consolidated Financial Statements

____________________________________________________________________________________________________

NOTE 1 — ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Organization:

Mines Management, Inc. (the Company) is a publicly held Idaho corporation incorporated in 1947.  The Company acquires, explores, and develops mineral properties principally in North America.  The Company performed exploration activities in South America in 2002.

Summary of Significant Accounting Policies:

a.

The accompanying consolidated financial statements include the accounts of Mines Management, Inc., and its wholly-owned subsidiary, Newhi, Inc.  Intercompany balances and transactions have been eliminated.  Newhi, Inc., was formed by the Company for the purpose of merger with Heidelberg Silver Mining Company, Inc.  In the merger, completed on April 15, 1988, Heidelberg Silver Mining Company, Inc., was merged into Newhi, Inc.  To effect the merger, the Company issued 367,844 shares of its previously unissued common stock.  Also in connection with this merger, the Company issued 11,117 shares of common stock and paid $4,446 as a finder’s fee.  

b.

All exploration expenditures are expensed as incurred.  Significant property acquisition payments for active exploration properties are capitalized.  If no minable ore body is discovered, previously capitalized costs are expensed in the period the property is abandoned.  Once a feasibility study has been completed, approved by management, and a decision is made to put the ore body into production, expenditures to develop new mines, to define further mineralization in existing ore bodies and to expand the capacity of operating mines, are capitalized and amortized on a units of production basis over proven and probable reserves.  Should a property be abandoned, its capitalized costs are charged to operations.  The Company charges to operations the allocable portion of capitalized costs attributable to properties sold.  Capitalized costs are allocated to properties sold based on the proportion of claims sold to the claims remaining within the project area.

c.

The Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amount may not be recoverable.  If the sum of estimated future net cash flows on an undiscounted basis is less than the carrying amount of the related asset grouping, an asset impairment is considered to exist.  The related impairment loss is measured by comparing estimated future net cash flows on a discounted basis to the carrying amount of the asset.  Changes in significant assumptions underlying future cash flow estimates may have a material effect on the Company’s financial position and results of operations.  To date no such impairments have been identified.

d.

Property and equipment are stated at cost.  Buildings and leasehold improvements are depreciated on the straight-line basis over an estimated useful life of 39 years.  Machinery and furniture are generally being depreciated using accelerated methods over estimated useful lives ranging from 5 to 10 years.

e.

Basic and diluted loss per share is computed using the weighted average number of shares outstanding during the periods (11,461,043, 9,745,097 and 7,234,703 in the years ended December 31, 2005, 2004, and 2003 respectively).  Stock options and warrants outstanding are antidilutive and are not considered in the computation.

NOTE 1 — ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Summary of Significant Accounting Policies (continued):

f.

Cash and cash equivalents include cash on hand, cash in banks, investments in certificates of deposit with original maturities of 90 days or less, and money market funds.

g.

The Company’s financial instruments as defined by Statement of Financial Accounting Standards (SFAS) No. 107, Disclosures about Fair Value of Financial Instruments, include cash.  All instruments are accounted for on a historical cost basis, which, due to the short maturity of these financial instruments, approximates fair value at December 31, 2005.

h.

Deferred income tax is provided for differences between the bases of assets and liabilities for financial and income tax reporting.  A deferred tax asset, subject to a valuation allowance, is recognized for estimated future tax benefits of tax-basis operating losses being carried forward.

i.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results may differ from those estimates.

j.

The Company has adopted SFAS No. 143, Accounting for Asset Retirement Obligations, which establishes a uniform methodology for accounting for estimated reclamation and abandonment costs.  According to SFAS No. 143, the fair value of a liability for an asset retirement obligation (ARO) will be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made.  The ARO is capitalized as part of the carrying value of the assets to which it is associated, and depreciated over the useful life of the asset.

In March 2005, the Financial Accounting Standards Board (“FASB”) issued Interpretation (FIN) No. 47, Accounting for Conditional Asset Retirement Obligations, which clarifies that the term conditional asset retirement obligation, as used in SFAS No. 143 refers to a legal obligation to perform an asset retirement activity where the timing or method of settlement are conditional on a future event.  Where the obligation to perform the asset retirement activity is unconditional, even though uncertainty exists about the timing or method of settlement, the entity is required to recognize a liability for the fair value of the conditional retirement obligation if reasonably estimable.  FIN No. 47 also clarifies when an entity would have sufficient information to reasonably estimate fair value.  At December 31, 2005, no asset retirement liabilities have been recorded by the Company.

k.

Certain amounts in the prior-period financial statements have been reclassified for comparative purposes to  conform to current period presentation with no effect on previously reported net loss.

NOTE 1 — ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Summary of Significant Accounting Policies (continued):

l.

In December 2004, FASB issued SFAS No. 123R, Share-Based Payment, which revised SFAS No. 123 and superseded APB No. 25 and its related implementation guidance.  SFAS No. 123R requires measurement and recording to the financial statements of the costs of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award, recognized over the period during which an employee is required to provide services in exchange for such award.  Effective January 1, 2003, the Company adopted SFAS No. 123R, as amended by SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure.  The Company recognized stock-based compensation of $1,004,349 (of which $560,569 was for services performed by outside parties), $1,417,291 (of which $-0- was for services performed by outside parties), and $560,800 (of which $-0- was for services performed by outside parties) for the years ended December 31, 2005, 2004, and 2003, respectively.

For purposes of calculating the fair value of options, volatility for the three years presented is based on the historical volatility of the Company’s Ordinary Shares over its public trading life.  The Company currently does not foresee the payment of dividends in the near term.  The fair value for these options was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions:

The Montanore property (formerly the Noxon property) located in northwestern Montana includes 18 mining claims covering 355 acres plus one 5-acre patented mill site.  In August 2002, the Company acquired a controlling interest in the Montanore silver and copper deposit in Sanders County, Montana.  The Company received a quitclaim deed from Noranda Mineral Corp. (“Noranda”) when Noranda elected to withdraw from the project.  The mineral rights acquired by the Company are subject to a $0.20 per ton royalty, and a 5% net profits royalty which would commence after the operator has recovered all of its exploration and development costs.  In December 2002, the Company received a quitclaim deed to all intellectual property connected with studies that Noranda carried out on the project.

The Advance property consists of 720 acres of patented mineral rights.  Although the Company does not own the overlying surface rights to its patented mineral rights, it does have right of access to explore and mine.

The Iroquois property consists of 64 acres of patented mineral and surface rights and 15 unpatented mining claims containing 300 acres.

For the periods presented, the effective income tax rate differed from the expected rate because of the effects of annual changes in the deferred tax asset valuation allowance.  Changes in the deferred tax asset valuation allowance for the years ended December 31, 2005, 2004, and 2003, relate only to corresponding changes in deferred tax assets for those periods.

At December 31, 2005, the Company had federal tax-basis net operating loss carryforwards totaling approximately $6,800,000, which will expire in various amounts from 2005 through 2024.

NOTE 9 — COMMITMENTS:

On August 11, 2005, Mines Management was named as a co-defendant in a lawsuit filed by Montana Reserves Company (“MRC”) in the Superior Court of the State of Washington in Spokane County, Washington. Named as co-defendants are Noranda Minerals, Normin Corp., Mines Management and Newhi, Inc. The action seeks damages in connection with the conveyance of the Montanore property from Noranda to Newhi, and challenges the computation of a net proceeds royalty payable to MRC pursuant to a Royalty Agreement between Noranda and MRC in respect to the Montanore property.  Management does not believe that the outcome of this lawsuit will have a material adverse effect.
