NOTICE OF COMPULSORY ACQUISITION
for all the Outstanding Common Shares of Corriente Resources Inc.

June 4, 2010

To:		Holders of common shares of Corriente Resources Inc. who did not accept the offer dated February 1, 2010, as extended on March 25, 2010 and April 26, 2010, made by CRCC-Tongguan Investment (Canada) Co., Ltd., a wholly-owned direct subsidiary of CRCC-Tongguan Investment Co., Ltd., a jointly-owned direct subsidiary of Tongling Nonferrous Metals Group Holdings Co., Ltd. and China Railway Construction Corporation Limited.

PLEASE REFER TO THE INSTRUCTIONS ATTACHED HERETO

On February 1, 2010, CRCC-Tongguan Investment (Canada) Co., Ltd. (the “Offeror”) made an offer (the “Offer”) to purchase at a price of Cdn.$8.60 per share all of the issued and outstanding common shares (the “Common Shares”) of Corriente Resources Inc. (“Corriente”), including all Common Shares that may become issued and outstanding after the date of the Offer but before the expiry time of the Offer upon the exercise of options issued under Corriente’s stock option plan. The Offer expired at 5:00 p.m. (Vancouver time) on May 28, 2010 (the “Expiry Time”), and the Offeror has taken up and accepted for payment 76,478,495 Common Shares representing approximately 96.9% of the Common Shares on a fully-diluted basis.

The Offer indicated that if, within four months after the making of the Offer, the Offer has been accepted by persons who, in the aggregate hold at least 90% of the outstanding Common Shares as at the Expiry Time, the Offeror will, to the extent possible, acquire the remainder of the Common Shares (the “Remaining Shares”) from those shareholders who have not accepted the Offer (the “Remaining Shareholders”, which includes any person who subsequently acquired any Remaining Shares), pursuant to Section 300 of the Business Corporations Act (British Columbia) (the “BCBCA”), for the same consideration and on the same terms contained in the Offer (the “Compulsory Acquisition”).

The Offeror is hereby exercising its rights under the BCBCA to acquire all of the Remaining Shares and hereby gives notice pursuant to Section 300 of the BCBCA that:

(a)

the Offer was accepted by shareholders of Corriente (the “Accepting Shareholders”) who, in the aggregate, held at least 90% of the Common Shares, other than Common Shares already held at the date of the Offer by, or by a nominee for, the Offeror or its affiliate;

(b)

the Offeror has taken-up and accepted for payment the Common Shares held by the Accepting Shareholders;

(c)

under the BCBCA, upon sending this Notice to a Remaining Shareholder, the Offeror is, subject to paragraph (d) below, entitled and bound to acquire all of the Remaining Shares of such Remaining Shareholder for the same consideration and on the same terms as the Common Shares that were acquired under the Offer; and

(d)

a Remaining Shareholder may, within two months from the date of this Notice, apply to the Supreme Court of British Columbia (the “Court”) for an order setting the price and terms of payment for such Remaining Shareholder’s Remaining Shares and any consequential orders or directions that the Court considers appropriate.

Where the Court has not, on application made by a Remaining Shareholder to whom this Notice was given, ordered otherwise, the Offeror must, no earlier than two months after the date of this Notice or, if an application to the Court by a Remaining Shareholder to whom this Notice was given is then pending, then after that application has been disposed of, send a copy of this Notice to Corriente and pay or transfer to Corriente the cash consideration payable by the Offeror for the Remaining Shares that the Offeror is entitled to acquire. On receiving such notice and cash consideration, Corriente must register the Offeror as a shareholder of Corriente with respect to all the Remaining Shares. The cash consideration received by Corriente from the Offeror will be held by Corriente, or a trustee approved by the Court, in trust for the Remaining Shareholders.

The Offeror intends to transfer the cash consideration for, and become registered as a shareholder with respect to, the Remaining Shares on or about August 4, 2010. In order to prevent a delay in receiving the purchase price for your Remaining Shares, the Offeror recommends that you complete the enclosed Transmittal and return it together with the certificate(s) representing your Remaining Shares to Computershare Investor Services Inc. (the “Depositary”) at the address set forth in the instructions attached hereto, within two months of the date of this Notice. Please note that interest will not be payable, under any circumstances, on amounts representing the purchase price for any Remaining Shares.

If you have already deposited all of your Common Shares under the Offer, no further action is required by you.

Remaining Shareholders are advised to consult their tax advisors to determine the particular tax consequences of the disposition of their Remaining Shares pursuant to the Compulsory Acquisition.

The foregoing is only a summary of the statutory right of Compulsory Acquisition. The summary is not intended to be complete and is qualified in its entirety by the provisions of Section 300 of the BCBCA. Remaining Shareholders should refer to Section 300 of the BCBCA for the full text of the relevant statutory provisions. Section 300 of the BCBCA is complex and requires strict adherence to notice and timing provisions, failing which certain rights available to Remaining Shareholders may be lost or altered. Remaining Shareholders who wish to be better informed about those provisions should consult their own legal advisors.

INSTRUCTIONS TO NOTICE OF COMPULSORY ACQUISITION

Within two months of the date of this Notice, a Remaining Shareholder should:

(A)

to receive the purchase price of Cdn.$8.60 per share for such Remaining Shareholder’s Remaining Shares without delay, complete the enclosed Transmittal and deliver the same to the Depositary at the address specified below together with the certificate(s) representing such Remaining Shareholder’s Remaining Shares; or

(B)

apply to the Court for an order setting the price and terms of payment for such Remaining Shareholder’s Remaining Shares and any consequential orders or directions that the Court considers appropriate.

Questions or requests for assistance may be directed to the Depositary, whose contact details are provided above.

Any cheque(s) mailed in accordance with the Notice of Compulsory Acquisition and this Transmittal will be deemed to be delivered at the time of mailing.

6.		Substitute Form W-9 for U.S. Shareholders Only

     United States federal income tax law generally requires a U.S. Shareholder who receives cash in exchange for Common Shares to provide the Depositary with its correct Taxpayer Identification Number (“TIN”), which, in the case of a Shareholder who is an individual, is generally the individual’s social security number. If the Depositary is not provided with the correct TIN or an adequate basis for an exemption, such holder may be subject to penalties imposed by the Internal Revenue Service and backup withholding in an amount equal to 28% of the gross proceeds of any payment received hereunder. If withholding results in an overpayment of taxes, a refund may be obtained by filing a U.S. tax return.

     To prevent backup withholding, each U.S. Shareholder must provide its correct TIN by completing the “Substitute Form W-9” set forth in this document, which requires the Shareholder to certify under penalties of perjury, (1) that the TIN provided is correct (or that such holder is awaiting a TIN), (2) that the holder is not subject to backup withholding because of an exemption and has either not been notified by the IRS that its is subject to backup withholding as a result of a failure to report all interest or dividends or has been notified by the IRS that it is no longer subject to backup withholding, and (3) that the holder is a U.S. citizen or other U.S. person. For this purpose, you are considered a U.S. person if you are an individual who is a U.S. citizen or U.S. resident alien, a partnership, corporation, company, or association created or organized in the United States or under the laws of the United States, an estate (other than a foreign estate), or a domestic trust (as defined in Regulations section 301.7701-7).

     Exempt holders (including, among others, all corporations) are not subject to backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt holder must enter its correct TIN in Part 1 of Substitute Form W-9, write “Exempt” in Part 2 of such form, and sign and date the form. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W‑9 (the “W-9 Guidelines”) for additional instructions.

     If Common Shares are held in more than one name or are not in the name of the actual owner, consult the enclosed W-9 Guidelines for information on which TIN to report.

     If a U.S. Shareholder does not have a TIN, such holder should: (i) consult the enclosed W-9 Guidelines for instructions on applying for a TIN, (ii) write “Applied For” in the space for the TIN in Part 1 of the Substitute Form W-9, and (iii) sign and date the Substitute Form W-9 and the Certificate of Awaiting Taxpayer Identification Number set forth in this document. In such case, the Depositary

may withhold 28% of the gross proceeds of any payment made to such holder prior to the time a properly certified TIN is provided to the Depositary, and if the Depositary is not provided with a TIN within sixty (60) days, such amounts will be paid over to the Internal Revenue Service.

     If a Shareholder has a U.S. address, but is not a U.S. Shareholder, such holder is required to submit an appropriate and properly completed IRS Form W-8 Certificate of Foreign Status, signed under penalties of perjury. Such appropriate IRS Form W-8 may be obtained from the Depositary.

     A SHAREHOLDER WHO FAILS TO PROPERLY COMPLETE THE SUBSTITUTE FORM W-9 SET FORTH IN THIS TRANSMITTAL OR, IF APPLICABLE, THE APPROPRIATE IRS FORM W-8 MAY BE SUBJECT TO BACKUP WITHHOLDING OF 28% OF THE GROSS PROCEEDS OF ANY PAYMENTS MADE TO SUCH HOLDER PURSUANT TO THE COMPULSORY ACQUISITION.

7.		Currency of Payment

     All amounts payable pursuant to the Compulsory Acquisition will be paid in Canadian dollars.

8.		Failure to Submit Properly Completed Transmittal

     If a Shareholder fails to submit a properly completed Transmittal or does not submit a Transmittal with the certificate(s) representing Common Shares, then the cheque representing payment for such Common Shares will be mailed to the address of the Shareholder as it appears on the securities register maintained by or on behalf of the Company.

9.		Miscellaneous

(a)

If the space in the box in this Transmittal entitled “Common Shares of the Company” is insufficient to list all certificates for Common Shares, additional certificate numbers and number of Common Shares may be included on a separate signed list affixed to this Transmittal.

(b)

If the Common Shares are registered in different forms (e.g. “John Doe” and “J. Doe”), a separate Transmittal should be signed for each different registration.

(c)

Before completing this Transmittal, you are urged to read the accompanying Notice of Compulsory Acquisition.

(d)

Additional copies of the Notice of Compulsory Acquisition and this Transmittal may be obtained without charge on request from the Depositary at its address provided on the back page of this Transmittal.

10.		Lost Certificates

     If a share certificate has been lost or destroyed, this Transmittal should be completed as fully as possible and forwarded, together with a letter describing the loss, to the Depositary at the address provided on the back of this Transmittal. The Depositary will forward such letter to the Company’s registrar and transfer agent so that the registrar and transfer agent may provide replacement instructions. If your certificate has been lost or destroyed, you may be required to provide proof that the certificate was lost or destroyed, an indemnity, or any other reasonable document or action at the request of the Company.

11.		Assistance

     Questions or requests for assistance in completing this Transmittal and depositing Common Shares with the Depositary may be directed to the Depositary, whose contact details are provided at the end of this document. Shareholders whose Common Shares are registered in the name of an investment advisor, stockbroker, bank, trust company or other nominee should immediately contact such nominee for assistance in depositing their Common Shares pursuant to the Compulsory Acquisition.

Certain penalties may also apply.

Penalties

Civil Penalty for False Information With Respect to Withholding. — If you make a false statement with no reasonable basis that results in no backup withholding, you may be subject to a U.S. $500 penalty.

(3)

Criminal Penalty for Falsifying Information. — Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
