Three-month period ended March 31, 2010

(expressed in Canadian dollars unless otherwise noted)

1	Nature of operations and offer to purchase the company
	Corriente Resources Inc. and its subsidiaries (collectively, “Corriente” or “the company”) are engaged in the exploration and development of mineral properties primarily in Ecuador, South America. The company considers itself to be a development stage enterprise.
	The business of mining and exploring for minerals involves a high degree of risk and there can be no assurance that current exploration and development programs will result in profitable mining operations. The recoverability of amounts shown for mineral properties is dependent upon the discovery of economically recoverable reserves, receipt of necessary permits and regulatory approvals, the ability of the company to obtain financing to complete its development and future profitable operations or sale of the properties. The investment in and expenditures on mineral properties comprise a significant portion of the company’s assets.
	On December 28, 2009, the company announced that it had signed a definitive agreement (the “Support Agreement”) with CRCC-Tongguan Investment Co., Ltd. (the “Offeror”), Tongling Nonferrous Metals Group Holdings Co., Ltd. ("Tongling") and China Railway Construction Corporation Limited ("CRCC"), under which the Offeror has agreed to make an offer to acquire all of the company’s outstanding shares (the “Offer”) for $8.60 per share in cash, equivalent to approximately $679 million on a fully-diluted basis.
	On February 1, 2010, the Offeror’s formal offer and take-over bid circular was mailed to shareholders, together with the company’s directors’ circular (the “Offer Circulars”), which included the unanimous recommendation of Corriente’s Board of Directors that shareholders accept the Offer. On March 24, 2010, the Offeror announced that the initial March 25, 2010 expiry date of the Offer was being extended to April 28, 2010. Subsequently on April 26, 2010, the Offeror announced that the April 28, 2010 expiry date of the Offer was being extended to 5:00 pm (Pacific Time) on May 28, 2010. The Offer is subject to a number of conditions which are set out in the Offer Circulars.
2	Significant accounting policies
	Basis of presentation
	These unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in Canada. They do not include all of the information and disclosures required by Canadian GAAP for audited annual financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included in these financial statements. The unaudited interim consolidated financial statements should be read in conjunction with the company’s audited annual consolidated financial statements including the notes thereto for the year ended December 31, 2009.
	The accounting policies followed by the company are set out in note 2 to the audited annual consolidated financial statements for the year ended December 31, 2009 and have been consistently followed in the preparation of these unaudited interim consolidated financial statements.
3	Mineral properties
	Corriente Copper Belt, Ecuador
	Under various agreements signed and completed with certain Ecuadorian subsidiaries of BHP Billiton Plc ("BHP Billiton"), the company has earned a 100% interest in BHP Billiton’s mineral properties located in the Rio Zamora copper porphyry district (the Corriente Copper Belt) in southeast Ecuador. This required the issue of shares to BHP Billiton and the expenditure of exploration funds under the terms of these agreements. Additionally, these mineral properties are subject to a 2% Net Smelter Royalty (“NSR”) payable to BHP Billiton, though the company has options to reduce the NSR to 1% for the Mirador/Mirador Norte, Panantza and San Carlos mineral properties upon the payment of US$2 million to BHP Billiton for each such option exercised.

Other

The balance comprises the expenditures incurred to March 31, 2010 to develop the La Florida, San Luis, San Marcos, San Miguel and Sutzu copper exploration targets in the Corriente Copper Belt, and the company’s proposed concentrate shipping port facility in Machala, Ecuador.

Measurement uncertainty

On January 29, 2009, a new Mining Law was enacted which, together with the Regulations to the Mining Law signed by the President of Ecuador on November 4, 2009, establishes the new legal framework for mining in Ecuador. However, the terms and conditions of the Exploitation Agreements which will cover the final development and production phases of a mining project have yet to be developed, creating some uncertainty regarding the future of the mining industry in Ecuador.

To date, the company’s discussions with the Ministry of Non-Renewable Natural Resources (“MNNR”, formerly the Ministry of Mining and Petroleum) and legal counsel have not identified any conditions that would result in a determination of a material impairment in the carrying value of the company’s concessions.

	$	2,477	$	2,347

Under the new legislative and regulatory framework which the Government of Ecuador implemented for the mining industry in 2009, the MNNR is responsible for the Environmental Impact Assessment (“EIA”) process. An EIA is required before any single stage of work (e.g., initial exploration, advanced exploration, construction and operation) can proceed for a mining project in Ecuador. The Ministry of Environment of Ecuador (“MAE”) has taken over responsibility for the Environmental Management Plan (“EMP”) component of the EIA, and as a result, the guarantee that is required to secure the obligations of a project’s EIA is now required to be issued in favour of the MAE. The amount of the required guarantee is reviewed annually by the MAE in conjunction with the MAE’s annual audit of the company’s EMP’s.

To secure the company’s project guarantees, which have been issued by a US bank, the company is required to have cash deposits in place, which vary in amount depending upon the related project’s stage of development and the bank’s guarantee deposit requirements.

6	Share capital

a)	Authorized
	Unlimited common shares, without par value
b)	Issued
	See Consolidated Statements of Changes in Shareholders’ Equity.
c)	Stock options
	The company has in place an incentive stock option plan dated November 1996, last amended April 18, 2006 (the “Option Plan”) for directors, officers, employees and consultants to the company and its subsidiaries. The Option Plan provides that the directors of the company may grant options to purchase common shares (“Options”) on terms that the directors may determine, within the limitations of the Option Plan. The number of common shares available for the Options under the Option Plan and all other share compensation arrangements of the company is set at a rolling maximum number that shall not be greater than 10% of the company’s current outstanding number of shares outstanding at any given time. The exercise price of the Option cannot be lower than the closing market price of the shares on the trading day immediately prior to the date of grant of the Option. As at March 31, 2010, Options to purchase a total of 3,572,500 (December 31, 2009 – 3,572,500) shares were outstanding and 2,361,887 (December 31, 2009 – 2,220,939) of the outstanding Options had vested.
	Options granted have the following vesting provisions:

• Options granted to executive officers, directors and other head office personnel vest on the basis of 1/16th of the total each quarter (from grant date), with such vesting being accelerated based on a change in control of Corriente or the attainment of clearly identified milestones, as determined by the company’s Directors.

• Options granted to subsidiary personnel vest on a cumulative basis of 50% of the total granted after 12 months from the grant date, 75% of the total granted after 18 months from the grant date and 100% of the total granted after 24 months from grant date, with such vesting being accelerated based on a change in control of Corriente, as determined by the company’s Directors.

Three-month period ended March 31, 2010

(expressed in Canadian dollars unless otherwise noted)

For the three-month period ended March 31, 2010, the company recognized a stock-based compensation charge of $506,000 (2009 – $617,000), of which $189,000 (2009 – $340,000) is included in salaries, benefits and stock-based compensation, $26,000 (2009 – $Nil) is included in corporate development and shareholder expenses and $291,000 (2009 – $277,000) is capitalized in mineral properties.

There were no Options granted during the three-month period ended March 31, 2010. The weighted average fair value of Options granted during the three-month period ended March 31, 2009 was $2.08 per share, as estimated using the Black-Scholes Option Pricing Model with the following assumptions:

	Three-month periods
	ended March 31,
	2010	2009
Risk-free interest rate	N/A	1.55%
Expected dividend yield	N/A	–
Expected stock price volatility	N/A	68%
Expected option life in years	N/A	4.25

Option pricing models require the input of highly subjective assumptions including expected price volatility. Changes in the subjective input assumptions can materially affect the fair value estimate.

A summary of changes to the Options outstanding and exercisable during the three-month periods ended March 31, 2010 and 2009 is as follows:

	2010			2009
			Weighted				Weighted
			average				average
	Number of		exercise	Number of			exercise
	options		price	options			price
Options outstanding – beginning of period	3,572,500	$	4.98	2,910,000		$	4.52
Granted	–		–	300,000			3.89
Exercised	–		–	–			–
Forfeited	–		–	(115,000	)		4.68
Options outstanding – end of period	3,572,500	$	4.98	3,095,000		$	4.45
Options exercisable – end of period	2,361,887	$	4.54	1,612,508		$	4.32

In accordance with the terms of the Option Plan, all unvested Options will be vested prior to the expiry of the Offer (note 1) in order to allow their holders to conditionally exercise the Options and tender the shares issued on exercise to the Offer (the “Option Shares”).

Although Options may be exercised conditional on the Offeror taking up the shares deposited under the Offer, the Optionholder must pay in full the exercise price of the Options before the Option Shares can be issued and deposited under the Offer. In order to facilitate the exercise of the Options, the company will make available to the Optionholders an optional short-term loan facility (the “Loan Facility”) intended to bridge the gap between an Optionholder’s payment to the company of the exercise price for their Option Shares, and their receipt of the purchase price for the Option Shares tendered to the Offer.

Should the Offer not close, the exercise of these Options would be reversed, any Loan Facility obligation cancelled and the Options would all be fully vested.

7	Related party transactions and balances
	In June 2007, the company completed the spin-off of its Caya 36 and Piedra Liza gold target assets to Q2 Gold Resources Inc. (“Q2 Gold”) by means of a Plan of Arrangement (the “Arrangement”). Q2 Gold has common officers and a common Board of Directors, except that Q2 Gold has one additional director who is independent of Corriente.
	In connection with the Arrangement and to assist Q2 Gold with its business objectives, Corriente and Q2 Gold entered into a collateralized, interest-bearing convertible loan agreement dated April 23, 2007, pursuant to which Corriente agreed to lend Q2 Gold up to $750,000 including accrued interest, to be advanced in instalments (the “Convertible Loan”). By amendments dated September 25, 2008 and December 3, 2009, the maximum facility amount of the Convertible Loan was increased from $750,000 to $1,500,000 and the maturity date ultimately extended to December 31, 2010. No payments were made to the company by Q2 Gold in exchange for the extensions.
	The Convertible Loan principal and unpaid interest are due on the earlier of December 31, 2010 and the first date on which Q2 Gold obtains a prospectus filing receipt with respect to any of its securities in any province of Canada. At any time prior to maturity, Corriente can require Q2 Gold to convert, in whole or in part, the principal amount outstanding and accrued interest of the Loan into Q2 Gold Shares at a conversion price equal to $0.10 per share. Q2 Gold can repay any portion of the outstanding Loan at any time prior to maturity or conversion. The company believes the conversion feature of the Convertible Loan is not material, therefore recognition and measurement of the embedded derivative is not being presented.
	The current state of financial markets and the early-stage nature of Q2 Gold’s exploration assets makes it uncertain that Q2 Gold will be able to raise the necessary debt or equity capital to repay the Convertible Loan prior to maturity. In the event of any default in the repayment of the Convertible Loan, the Q2 Gold assets which collateralize the Convertible Loan would become property of the company in accordance with the terms of the agreement. Management believes that the Q2 Gold assets would have a fair value greater than or equal to the current carrying value of the Convertible Loan. Significant changes in the fair value of the underlying assets could have an impact on the company up to a maximum of the carrying value of the Convertible Loan.

	Corriente also provides certain non-technical management services to Q2 Gold which include, but are not limited to, office, general accounting, administrative and shareholder services, pursuant to a management services agreement (the “Agreement”). The Agreement provides for a fee of $10,000 per month for such services, which is accrued pursuant to the Convertible Loan.
	For the three-month period ended March 31, 2010, the company accrued $30,000 (2009 – $30,000) and $19,000 (2009 – $14,000) in respect of administrative services and accrued interest on the Convertible Loan, respectively.
	The foregoing related party transactions are recorded at the exchange amount, which is the amount of consideration paid or received as established and agreed to between the parties.
	At March 31, 2010, the balance of the Convertible Loan receivable from Q2 Gold, including management fees and accrued interest, was $1,420,000 (December 31, 2009– $1,292,000).
