Alamos Reports First Quarter 2018 Results

Record Quarter Drives Increase in Full Year Production Guidance

Toronto, Ontario (May 1, 2018) - Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported its financial results for the first quarter ended March 31, 2018 and reviewed its operating, exploration and development activities.

“We delivered another record quarter of production and given the strong start to the year, we’ve increased full year production guidance to a range of 490,000 to 530,000 ounces. The increase was driven by stronger than expected performances from our Mulatos and Island Gold mines, the latter establishing a new record in its first full quarter as part of Alamos. Our financial performance continues to improve with strong free cash flow growth expected from our operations into the second half of the year reflecting higher production and lower costs,” said John A. McCluskey, President and Chief Executive Officer.

First Quarter 2018 Highlights

• Produced a record 128,900 ounces of gold, above budget and 34% higher than the first quarter of 2017 driven by strong performances from Mulatos and Island Gold.This marks the fourth consecutive quarter of record production

• Increased 2018 production guidance at both Mulatos and Island Gold, bringing Company-wide guidance to a range of 490,000 to 530,000 ounces of gold

• Island Gold reported record quarterly gold production of 28,100 ounces, in its first full quarter as part of Alamos. Mine-site all-in sustaining costs¹ of $633 per ounce were well below guidance and the operation generated $9.8 million in mine-site free cash flow¹. As a result of this strong performance, production guidance at Island Gold has been increased to between 95,000 and 105,000 ounces for 2018

• Sold 130,045 ounces of gold at an average realized price of $1,331 per ounce for record revenues of $173.1 million

• Cost of sales of $1,113 per ounce, total cash costs¹ of $789 per ounce and all-in sustaining costs ("AISC")¹ of $935 per ounce were all down from the first quarter of 2017, with total cash costs and AISC decreasing 5% and 8%, respectively

• Reported adjusted net earnings¹ of $12.3 million or $0.03 per share¹, reflecting adjustments for unrealized foreign exchange losses recorded within both deferred taxes and foreign exchange of $10.8 million, as well as other one-time items

• Reported net earnings of $0.6 million, or $0.00 per share

• Generated cash flow from operating activities of $58.8 million ($62.6 million or $0.16 per share, before changes in working capital¹), reflecting record production, lower cash costs and stronger operating margins

• Generated $24.3 million in mine-site free cash flow¹, and $7.3 million of company-wide free-cash flow¹ in the first quarter, both ahead of budget, reflecting a higher realized gold price and stronger production at Mulatos and Island Gold

• Ended the quarter with no debt and $231.8 million in cash and cash equivalents, up from $200.8 million as of December 31, 2017

• Liquidated the Company's equity positions in AuRico Metals and Corex Gold, generating proceeds of $24.9 million and realizing a gain of $14.3 million recorded directly in retained earnings (deficit)

• Announced a semi-annual dividend of $0.01 per share, or $3.9 million, paid to shareholders on April 30, 2018

⁽⁵⁾  Capital guidance at Kirazlı reduced to $25 million from the original budget of $100 million.

The Company continues to deliver on its strategic priorities of increasing cash flow from its operations while advancing its portfolio of low-cost development projects. In 2017, this included reporting record gold production and an 8% reduction in all-in sustaining costs.

This strong operational performance continued into the first quarter of 2018 with production of 128,900 ounces of gold, exceeding budget and setting a new quarterly record. This marks the fourth consecutive quarter of record production. Reflecting the strong start to the year, the Company has increased its 2018 production guidance at both Island Gold and Mulatos by 5,000 ounces, bringing the revised production guidance to a range of 490,000 to 530,000 ounces, representing a 19% increase over 2017 (based on the mid-point of guidance). All-in sustaining costs are expected to average $950 per ounce, supporting increasing operating margins and mine-site free cash flow. Capital spending at the four operating mines is expected to total between $146 and $165 million for the year.

Consistent with budget, production in the second quarter of 2018 is expected to be approximately 125,000 ounces, at slightly higher all-in sustaining costs than the first quarter as a result of additional sustaining capital. The Company expects stronger production from Young-Davidson to offset slightly lower production from Island Gold and Mulatos. In the second half of 2018, the Company anticipates stronger gold production, lower total cash costs and a lower rate of capital spending, all of which is expected to contribute to higher mine-site free cash flow compared to the first half of the year.

Young-Davidson produced 41,000 ounces in the first quarter and is expected to produce between 200,000 and 210,000 ounces for the full year at mine-site all-in sustaining costs of $850 per ounce. Similar to 2017, the Company expects stronger gold production in the second quarter and more notably in the second half of 2018 driven by higher underground grades and mining rates. Combined with lower total cash costs and a reduced rate of capital spending, this will drive stronger mine-site free cash flow in the second half of 2018.

Island Gold produced 28,100 ounces of gold in the first quarter, exceeding its budget and setting a new quarterly record. Given the outperformance in the first quarter, the operation is now expected to produce between 95,000 and 105,000 ounces in 2018, a 5% increase from previously guided levels, at mine-site all-in sustaining costs of $825 per ounce. The Phase I expansion of the Island Gold mill to 1,100 tpd remains on track and is expected to be completed

T R A D I N G S Y M B O L : T S X : A G I N Y S E : A G I

by the end of the third quarter. This is anticipated to drive production growth at lower costs in 2019 and beyond. Accordingly, the Company expects significant free cash flow growth in 2019.

In parallel to the Phase I mill expansion, the Company is pursuing an aggressive exploration program at Island Gold which has been successful in driving nearly a 400% increase in Mineral Reserves and a 60% increase in the Mineral Reserve grade since 2014.

Ongoing exploration success will be incorporated into an evaluation of the most effective and economic approach to a Phase II expansion of the operation beyond 1,100 tpd.

Total production from the Mulatos district (including La Yaqui Phase I) increased to 46,000 ounces in the first quarter, also exceeding budget. As a result, Mulatos is now expected to produce between 155,000 to 165,000 ounces in 2018, a 3% increase from previously guided levels, at mine-site all-in sustaining costs of $900 per ounce.

El Chanate produced 13,800 ounces in the first quarter and is expected to produce 40,000 to 50,000 ounces for the full year. This is down from 2017 reflecting lower mining rates with mining activities expected to cease mid-2018. Given the long leach cycle at El Chanate, the Company expects to benefit from ongoing gold production beyond 2018 through residual leaching. This will be lower cost and higher margin production, with mining activities completed, and is expected to drive higher mine-site free cash flow from the operation.

The Company expects combined annual gold production of at least 500,000 ounces from its existing operations in 2019 and 2020 with low cost production growth from Island Gold replacing production from El Chanate. Consolidated all-in sustaining costs are expected to decrease in 2019 reflecting the completion of the Phase I expansion at Island Gold and end of the 5% royalty at Mulatos, with a further decline expected in 2020 reflecting higher underground mining rates at Young-Davidson. Similarly, capital spending at existing operations is expected to trend lower in 2019 and 2020 reflecting the completion of the Phase I expansion at Island Gold and lower mine infrastructure at Young-Davidson. Increased production combined with declining operating costs is expected to result in strong free cash flow growth over the next three years.

Capital spending on development projects, including capitalized exploration, is dependent on timing of receipt of the GSM (Business Opening and Operation) permit for the Kirazlı project, located in Turkey. On April 18, 2018, a snap election was called in Turkey with early parliamentary and presidential elections scheduled to be held on June 24, 2018. The Company does not anticipate receiving the GSM permit until after the election, which will delay construction activities planned for this year. As a result, the Company is revising its 2018 capital budget for Kirazlı to $25 million, down from $100 million, with spending focused on specific infrastructure projects, notably road, powerline, and water reservoir construction. The Company will update its 2018 capital budget once the GSM permit has been received allowing for the ramp up of full scale construction activities.

In addition to capital spending in Turkey, a total of $46 million is budgeted for development at Cerro Pelon, La Yaqui Grande and Lynn Lake as well as capitalized exploration at all sites. Total exploration spending of $36 million will be focused on Island Gold and Mulatos for the remainder of the year.

The Company is well positioned to fund this growth having significantly de-risked its balance sheet over the past year. The Company is debt free with growing cash flow from its operations and over $630 million of cash and available liquidity under the Company's credit facility.

⁽⁴⁾  Grams per tonne of gold ("g/t Au").

Young-Davidson produced 41,000 ounces of gold in the first quarter of 2018, higher than the same period of 2017 but lower than the fourth quarter of 2017 due to lower underground mining rates and mined grades. The Company mined 585,060 tonnes of ore from underground in the first quarter, or 6,501 tpd, representing an increase over the prior year period. Underground mining rates were lower in the first quarter than in the fourth quarter of 2017, as a result of temporary constraints related to the paste fill sequence.

In addition, underground grades in the first quarter of 2.35 g/t Au were lower than the previous quarter and the same period of 2017 primarily as a result of mine sequencing. As previously guided, gold production is expected to increase in the second quarter and second half of 2018, with grades and underground mining rates expected to increase through the year.

During the first quarter, 669,287 tonnes, or 7,437 tpd, were processed through the mill with grades averaging 2.22 g/t Au, slightly higher from the prior year period. Mill throughput decreased compared to the fourth quarter of 2017 due to a scheduled liner change in January. Mill recoveries of 90% were in line with expectations and marginally higher than the prior year period.

Financial Review

For the three months ended March 31, 2018, revenues of $59.5 million were $5.9 million higher than the prior-year period, reflecting more ounces sold and a higher realized gold price.

In the first quarter of 2018, cost of sales of $57.0 million were higher than the prior year period reflecting higher tonnes mined and input costs. Cost of sales reflects mining and processing costs, royalties, and amortization expense.

Total cash costs in the first quarter were $824 per ounce, representing a 16% increase from the first quarter of 2017. The increase was attributable to higher gross costs driven by an increase in paste fill, maintenance and labour costs. Underground mining costs were higher than the prior year period due to a combination of increased paste fill activities and a higher allocation of development costs to operating expense, which impacts cost per tonne. The stronger

Canadian dollar had a nominal impact on total cash costs compared to the prior year as the Company has hedged the majority of its Canadian dollar operating and capital costs at budgeted foreign exchange rates for the first half of 2018. Mine-site AISC were $994 per ounce, 17% higher than the prior year period reflecting higher total cash costs and sustaining capital expenditures.

Capital expenditures totaled $22.9 million in the first quarter, 23% higher than the same period of 2017, reflecting the higher proportion of capital expected in the first half of 2018 as outlined in the Company's guidance. Capital spending in the first quarter was focused primarily on lateral development in the upper and lower mines, and lower mine infrastructure. Total capital expenditures in the first quarter included $7.6 million of sustaining capital and $15.3 million of growth capital.

Young-Davidson generated mine-site free cash flow of $4.5 million in the first quarter, lower than in recent quarters as a result of lower production and higher costs. The Company expects mine-site free cash flow to grow in subsequent quarters as production and operating margins increase and capital spending declines.

The first quarter of 2018 was the first full quarter that the Company owned and operated Island Gold. Operating and financial results exceeded budget with record production of 28,100 ounces of gold, an increase of 18% from the prior year period reflecting higher grades mined and milled. Given the strong first quarter performance, the Company is increasing 2018 production guidance to a range of 95,000 to 105,000 ounces.

The Company mined 84,655 tonnes of ore from underground in the first quarter of 2018, or 941 tpd, lower than the prior year period. The Company expects to ramp up mining rates in the second half of 2018 concurrent with the completion of the mill expansion to 1,100 tpd. Underground mining rates are expected to average 1,000 tpd in 2018, consistent with the rates achieved in 2017. Underground grades in the first quarter of 11.06 g/t Au were above budget and higher than the prior year period due to a combination of mine sequencing and a positive grade reconciliation. Grades are expected to be lower throughout the remainder of 2018.

During the first quarter, 82,105 tonnes or 912 tpd were processed through the mill, in line with the prior year period. Milled grades averaged 11.07 g/t Au, higher than the prior year period and previous quarter. Mill throughput is expected to average 980 tpd for the full year with milled grades expected to return to budgeted grades of between 8.3 and 8.9 g/t Au for the remainder of the year. Reflecting the return to budgeted grades, gold production is expected to decrease in the second and third quarters and ramp up in the fourth quarter following completion of the mill expansion.

Financial Review

With the Company acquiring Island Gold in November 2017, financial information prior to the acquisition date has not been included in the comparative table above.

For the three months ended March 31, 2018, Island Gold generated revenues of $36.6 million, on record production and higher realized gold prices. Cost of sales of $27.5 million reflect an ongoing amortization charge related to the

8 | Alamos Gold Inc

T R A D I N G S Y M B O L : T S X : A G I N Y S E : A G I

purchase price of the asset, which increases amortization to approximately $450 per ounce based on current mineral reserves and resources.

Total cash costs of $553 per ounce were below guidance levels of $575 per ounce, reflecting higher grades mined in the quarter. In addition, mine-site AISC of $633 per ounce were well below guidance of $825 per ounce driven primarily by lower sustaining capital spending in the first quarter. Mine-site AISC are expected to be higher for the remainder of 2018.

Capital expenditures totaled $13.9 million in the first quarter, with spending focused primarily on capitalized exploration, lateral development and the mill expansion. Total capital expenditures in the first quarter included $2.2 million of sustaining capital and $11.7 million of growth capital. Island Gold generated mine-site free cash flow of $9.8 million in the first quarter driven by stronger production and operating margins. The Company expects Island Gold to generate sufficient cash flow to fully fund its significant exploration program and the expansion to 1,100 tpd.

Mulatos exceeded budget for the first quarter of 2018 with gold production of 46,000 ounces, including approximately 8,000 ounces from La Yaqui Phase I which achieved initial production in September 2017. Production in the quarter was higher than the prior year period mainly due to the contribution from La Yaqui Phase I, slightly offset by lower grades mined at the main Mulatos pit. As a result of the strong start to the year, and continued underground mining at San Carlos, the Company has increased 2018 production guidance to a range of 155,000 to 165,000 ounces. Consistent with annual guidance, the Company expects production to decrease in the second half of the year following the end of production from San Carlos.

Total crusher throughput averaged a record 19,800 tpd, higher than the same period of 2017 reflecting the addition of La Yaqui Phase I. A total of 1,750,471 tonnes were stacked in the first quarter at a grade of 0.84 g/t Au, consistent with annual guidance. The waste-to-ore ratio of 0.91:1 decreased relative to the prior year period as a result of the addition of La Yaqui Phase I, which has a minimal waste-to-ore ratio.

In the first quarter of 2018, 30,389 tonnes were milled at an average grade of 8.11 g/t Au from San Carlos. Consistent with budget, the tonnes mined during the quarter were lower than the same period of 2017 and the fourth quarter of 2017 as the underground mine nears the end of its life. San Carlos and existing stockpiles had been expected to be depleted by the end of the first quarter, however; the Company has identified additional ore, which is expected to extend the life to mid-2018.

T R A D I N G S Y M B O L : T S X : A G I N Y S E : A G I

The ratio of ounces produced to contained ounces stacked and milled (or recovery ratio) was 83% in the quarter compared to 70% in the prior year period and guidance of 75%. The higher recoveries in the first quarter reflect the recovery of deferred production from the fourth quarter of 2017, as well as stronger than budgeted recoveries at La Yaqui Phase I.

Financial Review

For the three months ended March 31, 2018, revenues of $59.6 million were $12.0 million or 25% higher than the prior-year period reflecting a 15% increase in the number of ounces sold and a 10% higher realized gold price.

Cost of sales in the first quarter of $43.6 million were higher than the prior-year period as gross costs reflected higher tonnes stacked. Cost of sales reflects mining and processing costs, royalties, and amortization expense.

Total cash costs of $786 per ounce in the first quarter were 5% lower than $827 per ounce in the prior year period, reflecting the addition of lower cost La Yaqui Phase I production. Mine-site AISC in the quarter were $842 per ounce, 8% lower than the prior year period reflecting lower total cash costs and lower sustaining capital due to the timing of capital expenditures.

The substantial production and sales growth combined with higher gold prices and lower costs drove another strong quarter of cash flow, with Mulatos generating $8.9 million in mine-site free cash flow. The Mulatos operation is expected to generate strong cash flow in 2018, which will be used to advance the La Yaqui Grande and Cerro Pelon deposits through permitting, as well as funding exploration activities.

El Chanate produced 13,800 ounces of gold in the first quarter of 2018, down from 15,800 ounces in the prior year period reflecting lower stacking rates throughout 2017.

El Chanate is expected to continue to produce at lower than historical rates in 2018 as the mine reaches the end of mining activities by mid-year. Given the long leach cycle at El Chanate, the Company expects to benefit from ongoing gold production at decreasing rates into the second half of 2018 and beyond through residual leaching. This is expected to drive higher mine-site free cash flow the second half of the year.

In 2018 El Chanate continued to demonstrate an industry leading safety performance achieving milestones of over 3 years and 5.2 million hours without a lost time injury by the end of the first quarter.

Financial Review

For the three months ended March 31, 2018, revenue of $17.4 million was $2.4 million lower than the prior year period, reflecting fewer ounces sold, partially offset by higher realized gold prices.

Total cash costs of $1,176 per ounce and mine-site all-in sustaining costs of $1,191 per ounce in the first quarter were similar to the prior year period, reflecting a lower waste-to-ore ratio, and higher grades, offset by higher unit costs.

El Chanate generated positive mine-site free cash flow of $1.1 million in the quarter. This is expected to increase in the second half of the year as the mine transitions to residual leaching. Given El Chanate's higher cost structure, the Company has hedged all of its expected 2018 gold production through gold collar contracts, ensuring a minimum gold price of $1,290 and participation up to a price of $1,458 per ounce.

First Quarter 2018 Development Activities

Mulatos District

La Yaqui Grande and Cerro Pelon

The capital budget for Cerro Pelon in 2018 is $8 million which will be spent on engineering, permitting and early stage construction activities. The Cerro Pelon deposit is located approximately three kilometres from the existing Mulatos operation. Given its proximity to Mulatos’ infrastructure, ore from the Cerro Pelon open pit is expected to be trucked to the existing heap leach circuit for processing. The environmental impact assessment (“MIA”) for Cerro Pelon is expected to be finalized and submitted mid-2018. Following approval, construction and pre-stripping activities are expected to take approximately 18 months with initial production expected in 2020. Recently completed work includes the design of the waste rock dump, haulage road and crushing circuit.

La Yaqui Grande’s capital budget for 2018 is $5 million with spending focused on permitting and project engineering. The MIA is expected to be completed and submitted by the end of 2018 with construction and pre-stripping activities commencing in the latter part of 2019 and production in 2021. Similar to La Yaqui Phase I, La Yaqui Grande will be developed as a standalone, open pit, heap leach operation. La Yaqui Grande exploration activities in 2017 were successful in increasing Mineral Reserves by 28% to 644,000 ounces as at December 31, 2017 (14.3 million tonnes grading 1.4 g/t Au).

During the first quarter, spending on La Yaqui Grande and Cerro Pelon was $2.0 million, which included $1.1 million of capitalized exploration. The Company recently awarded the Engineering, Procurement and Construction Management contract for its Cerro Pelon and La Yaqui Grande projects.

Lynn Lake

The Company owns 100% of the Lynn Lake development project, in Manitoba, Canada. The Company released a positive Feasibility Study on the project in December 2017 outlining average annual production of 143,000 ounces over a 10 year mine life (170,000 ounces over its first six years) at average mine-site all-in sustaining costs of $745 per ounce.

The 2018 capital budget for Lynn Lake is $12 million, comprised of $8 million for development activities and $4 million for exploration. Development spending will be focused on baseline work in support of the Environmental Impact Study (“EIS”) for the project that will be submitted to satisfy federal and provincial environmental assessment requirements. The permitting process is expected to take approximately two years followed by two years of construction.

The Company began evaluating various opportunities to enhance the project’s economics, including modifications to the overall site layout, plant design and water management. During the first quarter, $1.3 million was spent at Lynn Lake mainly on project optimization and exploration activities.

Turkey

The Company has been granted the Environmental Impact Assessment and Forestry Permits for Kirazlı and is awaiting the GSM (Business Opening and Operation) permit, which is granted by the Çanakkale Governorship.

On April 18, 2018, a snap election was called in Turkey with early parliamentary and presidential elections scheduled to be held on June 24, 2018. The Company does not anticipate receiving the GSM permit until after the election, which will delay construction activities planned for this year. As a result, the Company is revising its 2018 capital budget for Kirazlı to $25 million, down from $100 million, with spending focused on surrounding infrastructure projects. The Company will update its 2018 capital budget once the GSM permit has been received allowing for the ramp up of full scale construction activities.

Ongoing development activities include power line construction, tree clearing, road relocation and construction of the water reservoir. Approximately 70% of tree clearing and 15% of the road realignment earthworks and have now completed. The Company has awarded several key contracts, including civil works, subject to the receipt of the GSM. For the first quarter, development expenditures at Kirazlı were $5.1 million.

Kirazlı is expected to produce more than 100,000 ounces of gold in its first full year of production at mine-site AISC of less than $400 per ounce. This is expected to drive company-wide production growth, while significantly lowering the Company’s cost profile.

Other

The Company capitalized $0.5 million related to the Esperanza Project and $0.2 million to Quartz Mountain during the quarter.

First Quarter 2018 Exploration Activities

Mulatos District, Mexico

The Company has a large exploration package covering 28,777 hectares with the majority of past exploration efforts focused around the Mulatos mine. Over the last three years, exploration has moved beyond the main Mulatos pit area and focused on prospects throughout the wider district. After significant exploration success at La Yaqui Grande over the past few years, the focus in 2018 has shifted to other parts of the district including El Carricito, El Halcon and El Jaspe.

In the first quarter of 2018, the Company invested $4.5 million in exploration activities within the Mulatos District, of which $1.1 million was capitalized and the remainder expensed. This included 14,792 metres (“m”) of diamond drilling and 1,059 m of reverse circulation drilling focused on both near-mine targets and regional targets including El Halcon and El Jaspe. Additionally, underground exploration of the San Carlos deposit concluded during the quarter.

At El Carricito, mapping and sampling continued during the first quarter with approximately 70% of the concession having been mapped to date. El Carricito will be a key focus of the 2018 exploration program with 10,000 m of scout drilling planned for the second half of this year.

Island Gold, Canada

Delineation drilling at Island Gold in 2017 was successful in increasing mineral reserves by 18%, net of mining depletion. In addition, the 2017 exploration drilling resulted in the addition of new mineral resources. The 2017 exploration program was also successful in outlining additional gold mineralization down plunge to the east. The majority of the exploration drill results in this area are not yet at the required drill spacing to allow for inclusion into the Inferred mineral resource category.

A key focus of the 2018 exploration program is on converting this newly outlined zone of mineralization into the Inferred mineral resource category. Other areas of focus include drilling, both beneath the existing mine infrastructure and to the west.

Surface exploration drilling

Surface exploration drilling totaled 9,187 m during the first quarter of 2018, with 12 holes completed as part of the directional exploration drilling campaign. The directional drilling targeted areas peripheral to the inferred mineral resource blocks below the 1,000 m level, with drill hole spacing ranging from 75 m to 100 m. The area being targeted by the surface directional drill program extends approximately 2,000 m in strike length between the 1,000 m and 1,500 m elevation below surface.

The surface directional drilling programs will continue in 2018 with a focus on defining new inferred mineral resources.

Underground exploration drilling

During the first quarter of 2018, a total of 8,865 m of underground exploration diamond drilling was completed in 44 holes from the 620 and 840 levels. The objective of the underground drilling is to identify new mineral resources close to existing mineral resource or reserve blocks.

Total expenditures across the surface and underground exploration drilling program at Island Gold during the first quarter of 2018 were $3.3 million, with $3.1 million capitalized.

Lynn Lake, Canada

Surface exploration drilling continued at Lynn Lake in the first quarter of 2018 with a total of 4,047 m drilled in nine holes. Exploration drilling was focused in the southern portion of the Lynn Lake Greenstone belt testing for the continuation of structures related to gold mineralization along strike of Burnt Timber and Linkwood, and testing two regional targets in the southern portion of the Lynn Lake Greenstone Belt.

Drilling will continue into the second quarter of 2018, and a regional exploration program will commence focused on refining existing high-priority exploration targets and generating a pipeline of prospective targets across the Lynn Lake Greenstone Belt.

A total of $4 million and 10,000 m of drilling is budgeted at the Lynn Lake project for 2018. Spending in the first quarter totaled $0.8 million.

Review of First Quarter Financial Results

During the first quarter of 2018, the Company sold 130,045 ounces of gold for total revenue of $173.1 million, a 43% increase compared to the prior year period. This was primarily driven by the Island Gold acquisition, which contributed 27,503 ounces, or $36.6 million in sales for the quarter, and a higher realized price of $1,331 per ounce compared to $1,225 per ounce in the prior year period (a $10.5 million benefit). The Company's realized gold price in the first quarter was $1,331 per ounce, above the average London PM fix of $1,329 per ounce.

For the first quarter of 2018, cost of sales were $144.7 million, compared to $110.1 million in the prior-year period.

Mining and processing costs were $96.9 million compared to $77.9 million in the prior-year period. The increased costs were mainly the result of the addition of Island Gold, which added $13.6 million of mining and processing costs in the period.

Consolidated total cash costs for the quarter were $789 per ounce, compared to $827 in the prior year period. The decrease in total cash costs is attributable to the addition of lower cost ounces from Island Gold and improved cost profile at Mulatos, partially offset by higher costs at Young-Davidson.

In the first quarter, AISC per ounce decreased to $935 from $1,014 in the prior year period. This was primarily driven by the addition of lower cost ounces from Island Gold, and lower sustaining capital expenditures.

Royalty expense was higher in the first quarter at $5.7 million, compared to $3.8 million in the prior year period, primarily due to the addition of Island Gold, and higher ounces sold at Mulatos.

Amortization of $42.1 million in the quarter was higher than the prior year period expense of $28.4 million. Amortization was $324 per ounce, up from $289 per ounce in the prior year period, though consistent with the fourth quarter of 2017. This reflected higher amortization at all operating sites and the addition of Island Gold which carries a higher amortization per ounce charge.

The Company recognized earnings from operations of $18.5 million in the quarter, compared to $2.2 million in the same period of 2017, driven by record production and gold sales and stronger operating margins at Mulatos and Island Gold.

The Company reported a net earnings of $0.6 million in the quarter, compared to net earnings of $0.1 million in the same period of 2017. Net earnings in the period were significantly impacted by foreign exchange movements, as the Company recorded a foreign exchange loss of $1.3 million, in addition to foreign exchange losses recorded within deferred income taxes. Reflecting these foreign exchange adjustments, the Company recorded adjusted net earnings¹ of $12.3 million or $0.03 per share.

Cautionary Note to U.S. Investors Concerning Measured, Indicated and Inferred Resources

The Company is required to prepare its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are materially different from the standards generally permitted in reports filed with the United States Securities and Exchange Commission. When describing resources we use the terms "measured", "indicated" or "inferred” resources which are not recognized by the United States Securities and Exchange Commission.  The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically or legally mineable proven or probable reserves. The estimation of inferred resources may not form the basis of a feasibility or other economic studies and involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources.

Non-GAAP Measures and Additional GAAP Measures

The Company has included certain non-GAAP financial measures to supplement its Consolidated Financial Statements, which are presented in accordance with IFRS, including the following:

• adjusted net earnings and adjusted earnings per share;

• cash flow from operating activities before changes in working capital and taxes received;

• company-wide free cash flow;

• total mine-site free cash flow;

• mine-site free cash flow;

17 | Alamos Gold Inc

T R A D I N G S Y M B O L : T S X : A G I N Y S E : A G I

• total cash cost per ounce of gold sold;

• all-in sustaining cost ("AISC") per ounce of gold sold;

• mine-site all-in sustaining cost ("Mine-site AISC") per ounce of gold sold;

• sustaining and non-sustaining capital expenditures; and

• earnings before interest, taxes, depreciation, and amortization

The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-GAAP financial measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Management's determination of the components of non-GAAP and additional measures are evaluated on a periodic basis influenced by new items and transactions, a review of investor uses and new regulations as applicable. Any changes in to the measures are dully noted and retrospectively applied as applicable.

Adjusted Net Earnings and Adjusted Earnings per Share

“Adjusted net earnings” and “adjusted earnings per share” are non-GAAP financial measures with no standard meaning under IFRS which exclude the following from net earnings:

• Foreign exchange gain (loss)

• Items included in Other loss

• Certain non-reoccurring items

• Foreign exchange gain (loss) recorded in deferred tax expense

Net earnings have been adjusted, including the associated tax impact, for the group of costs in “Other loss” on the consolidated statement of comprehensive income. Transactions within this grouping are: the fair value changes on non-hedged derivatives; the renunciation of flow-through exploration expenditures; and loss on disposal of assets. The adjusted entries are also impacted for tax to the extent that the underlying entries are impacted for tax in the unadjusted net earnings.

The Company uses adjusted net earnings for its own internal purposes. Management’s internal budgets and forecasts and public guidance do not reflect the items which have been excluded from the determination of adjusted net earnings. Consequently, the presentation of adjusted net earnings enables shareholders to better understand the underlying operating performance of the core mining business through the eyes of management. Management periodically evaluates the components of adjusted net earnings based on an internal assessment of performance measures that are useful for evaluating the operating performance of our business and a review of the non-GAAP measures used by mining industry analysts and other mining companies.

Adjusted net earnings is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The measure is not necessarily indicative of operating profit or cash flows from operations as determined under IFRS. The following table reconciles this non-GAAP measure to the most directly comparable IFRS measure.

Cash Flow from Operating Activities before Changes in Working Capital and Cash Taxes

“Cash flow from operating activities before changes in working capital and cash taxes” is a non-GAAP performance measure that could provide an indication of the Company’s ability to generate cash flows from operations, and is calculated by adding back the change in working capital and taxes received to “Cash provided by (used in) operating activities” as presented on the Company’s consolidated statements of cash flows. “Cash flow from operating activities before changes in working capital” is a non-GAAP financial measure with no standard meaning under IFRS.

The following table reconciles the non-GAAP measure to the consolidated statements of cash flows.

Company-wide Free Cash Flow

“Company-wide free cash flow" is a non-GAAP performance measure calculated from the consolidated operating cash flow, less consolidated mineral property, plant and equipment expenditures. The Company believes this to be a useful indicator of our ability to operate without reliance on additional borrowing or usage of existing cash company-wide. Company-wide free cash flow is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures of performance presented by other mining companies. Company-wide free cash flow should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Total Cash Costs per ounce

Total cash costs per ounce is a non-GAAP term typically used by gold mining companies to assess the level of gross margin available to the Company by subtracting these costs from the unit price realized during the period. This non-GAAP term is also used to assess the ability of a mining company to generate cash flow from operations. Total cash costs per ounce includes mining and processing costs plus applicable royalties, and net of by-product revenue and net realizable value adjustments. Total cash costs per ounce is exclusive of exploration costs.

Total cash costs per ounce is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The measure is not necessarily indicative of cash flow from operations under IFRS or operating costs presented under IFRS.

All-in Sustaining Costs per ounce and Mine-site All-in Sustaining Costs

The Company adopted an “all-in sustaining costs per ounce” non-GAAP performance measure in accordance with the World Gold Council published in June 2013. The Company believes the measure more fully defines the total costs associated with producing gold; however, this performance measure has no standardized meaning. Accordingly, there may be some variation in the method of computation of “all-in sustaining costs per ounce” as determined by the Company compared with other mining companies. In this context, “all-in sustaining costs per ounce” for the consolidated Company reflects total mining and processing costs, corporate and administrative costs, share-based compensation, exploration costs, sustaining capital, and other operating costs.

For the purposes of calculating "mine-site all-in sustaining costs" at the individual mine-sites, the Company does not include an allocation of corporate and administrative costs and share-based compensation, as detailed in the reconciliations below.

Sustaining capital expenditures are expenditures that do not increase annual gold ounce production at a mine site and excludes all expenditures at the Company’s development projects as well as certain expenditures at the Company’s operating sites that are deemed expansionary in nature. For each mine-site reconciliation, corporate and administrative costs, and non-site specific costs are not included in the all-in sustaining cost per ounce calculation.

All-in sustaining costs per gold ounce is intended to provide additional information only and does not have any standardized meaning under IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
