** The calculation of the foregoing percentage is based on 75,349,893 Common Shares issued and outstanding as of December 28, 2009 as represented in the Support Agreement described in Item 4 hereof.

Item 1. Security and Issuer

This Schedule 13D relates to the common shares, without par value (the “Common Shares”), of Corriente Resources Inc., a corporation incorporated under the laws of the Province of British Columbia, Canada (the “Issuer”). The principal executive offices of the Issuer are located at 520-800 West Pender Street, Vancouver, British Columbia, Canada V6C 2V6.

Item 2. Identity and Background

This Schedule 13D is being jointly filed by Tongling Nonferrous Metals Group Holdings Co., Ltd., a corporation incorporated under the laws of the People’s Republic of China (“Tongling”), China Railway Construction Corporation Limited, a corporation incorporated under the laws of the People’s Republic of China (“CRCC”), and CRCC-Tongguan Investment Co., Ltd., a corporation incorporated under the laws of the People’s Republic of China (the “Offeror” and, together with Tongling and CRCC, the “Reporting Persons”). The agreement among the Reporting Persons relating to the joint filing of this statement is attached as Exhibit 99.1 hereto. The Reporting Persons may be deemed to constitute a “group” within the meaning of Section 13(d)(3) of the Exchange Act with respect to the transactions described in Item 4 hereof. The Reporting Persons expressly disclaim that they have agreed to act as a group except as described herein.

Tongling, a state-owned corporation existing under the laws of the People’s Republic of China, is an integrated mining conglomerate, primarily engaged in copper mining, mineral processing, smelting and refining and copper products processing, as well as trade, scientific research and design, machine building, construction and installation, shaft and drift construction and other businesses. The address of the principal place of business and office of Tongling is Changjiang West Road, Tongling 244001, Anhui Province, People’s Republic of China.

CRCC, a state-owned, public corporation existing under the laws of the People’s Republic of China, is a large integrated construction enterprise, the activities of which comprise construction, survey, design and consultancy, manufacturing, logistics and goods and materials trade, capital investment operations and real estate development, among other things. The address of the principal place of business and office of CRCC is No. 40, Fuxing Road, Beijing 100855, People’s Republic of China.

The Offeror is jointly owned by Tongling and CRCC. Each of Tongling and CRCC directly owns 50% of the Offeror’s equity. The Offeror was incorporated under the laws of the People’s Republic of China on December 10, 2009. The Offeror has not carried on any material business or activity prior to the date hereof other than in connection with matters directly related to the transactions described in Item 4 hereof. The address of the registered and principal office of the Offeror is Economic and Technological Development Zone, Tongling 244000, Anhui Province, People’s Republic of China.

The name, citizenship, occupation and principal business address of each director and executive officer of each Reporting Person are listed in Schedule I hereto (the “Schedule I Persons”).

During the last five years, none of the Reporting Persons, or, to the Reporting Persons’ knowledge, any of the Schedule I Persons, has been (i) convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors) or (ii) party to a civil proceeding of a

Page 5 of 19

judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

As more fully described in Item 4 hereof, the Locked-Up Shareholders (as defined below) have entered into the Lock-Up Agreements (as defined below) to induce the Reporting Persons to enter into the Support Agreement (as defined below) described in Item 4 hereof. The Locked-Up Shareholders together are the record and/or beneficial owners of 9,429,541 Common Shares (including 2,005,000 Common Shares of which the Reporting Persons may acquire beneficial ownership within sixty days of December 28, 2009 through the exercise of options of the Issuer (“Options”) held by the Locked-Up Shareholders). Except as described below, the transactions contemplated by the Lock-Up Agreements (which are the reasons the Reporting Persons may be deemed to be beneficial owners of all such Common Shares) are not expected to require the expenditure of any funds.

As more fully described in Item 4 hereof, the Reporting Persons have entered into the Support Agreement, pursuant to which the Reporting Persons will make the Offer (as defined below). The Reporting Persons estimate that, if the Offeror acquires all of the Common Shares (on a fully-diluted basis), the total cash amount required to acquire such Common Shares will be approximately Cdn$679 million. The Offeror currently intends to use cash on hand and bank financing (to be arranged prior to the expiration of the Offer) to fund the aggregate cost of the acquisition of such Common Shares. CRCC and Tongling will provide financial support to the Offeror and guarantees in connection with such bank financing in proportion to their respective shareholdings in the Offeror.

Item 4. Purpose of Transaction

On December 28, 2009, the Reporting Persons entered into a Support Agreement (the “Support Agreement”) with the Issuer. Subject to the terms and conditions set forth in the Support Agreement, the Offeror agreed in the Support Agreement to make an offer no later than 11:59 p.m. (Vancouver time) on February 1, 2010 (subject to extension in certain circumstances) to purchase all of the outstanding Common Shares, including Common Shares issuable upon the exercise of Options held by the Locked-Up Shareholders, at a price of Cdn$8.60 in cash per Common Share (the “Offer”). Pursuant to the Support Agreement, Tongling and CRCC have unconditionally and irrevocably covenanted, jointly and severally, to cause the due and punctual performance by the Offeror of each of the Offeror’s obligations arising under the Support Agreement.

The Support Agreement also provides for, among other things, the following:

•

If, within four months after the making of the Offer by the Offeror, 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 of the Offer, the Offeror will, to the extent possible, acquire the remainder of the Common Shares from the Issuer’s shareholders who have not accepted the Offer pursuant to a compulsory acquisition under the laws of British Columbia.

Page 6 of 19

•

If the Offeror takes up and pays for such number of Common Shares under the Offer that, together with the Common Shares held by the Offeror and any of its nominees and affiliates, is equal to at least 66²/3% of the outstanding Common Shares as at the expiry time of the Offer, and a compulsory acquisition under the laws of British Columbia is not available, the Offeror will use its commercially reasonable efforts to acquire the balance of the Common Shares as soon as practicable, and in any event within 120 days of the expiry time of the Offer, by way of a statutory arrangement, amalgamation, amendment to articles, reorganization, consolidation, recapitalization or other type of acquisition transaction or transactions carried out for consideration per Common Share of not less than Cdn$8.60.

•

In the event the Offeror takes up and pays for under the Offer, or otherwise acquires, such number of Common Shares that, together with the Common Shares held by the Offeror and any of its nominees and affiliates, is equal to at least a simple majority of the outstanding Common Shares, the Issuer will assist the Offeror in connection with any proposed compulsory acquisition or subsequent acquisition transaction such that the Offeror may, in its sole discretion, undertake to pursue to acquire the balance of the Common Shares, provided that the consideration per Common Share offered in connection with such transaction is not less than Cdn$8.60.

The Support Agreement does not prohibit the Offeror or any of its affiliates from acquiring, directly or indirectly, additional Common Shares in the open market or in privately negotiated transactions or otherwise in accordance with applicable securities laws. Canadian and U.S. securities laws provide for certain limits on such acquisitions.

The Offeror currently intends to assign its rights and obligations under the Support Agreement to a direct or indirect wholly-owned subsidiary of the Offeror to be incorporated under the laws of British Columbia (the “BC Offeror”). The Offeror intends to satisfy its obligations under the Support Agreement in respect of the making of the Offer and the acquisition of Common Shares by causing the BC Offeror to make the Offer and acquire Common Shares in accordance with the Support Agreement.

The Offer will expire not earlier than 5:00 p.m. (Vancouver time) on the 36^th day after the Offer circular is mailed to all registered holders of Common Shares and Options, unless extended or withdrawn.

After the consummation of all of the transactions contemplated by the Support Agreement (including a compulsory acquisition or subsequent acquisition transaction, as the case may be), the Reporting Persons will beneficially own the entire equity interest in the Issuer and the Issuer will be an indirect wholly-owned subsidiary of the Offeror and a direct wholly-owned subsidiary of the BC Offeror.

Simultaneously with the execution and delivery of the Support Agreement, the Offeror entered into a Lock-Up Agreement (each a “Lock-Up Agreement”, and collectively, the “Lock-Up Agreements”) on December 28, 2009 with each of Daniel Carriere, Richard Clark, Anthony

Page 7 of 19

Holler, Darryl Jones, Ross McDonald, Dale Peniuk, Kenneth Shannon and David Unruh (each a “Locked-Up Shareholder”, and collectively, the “Locked-Up Shareholders”). Each Locked-Up Shareholder executed a Lock-Up Agreement substantially identical to the Form of Lock-Up Agreement attached hereto as Exhibit 99.3. Pursuant to the Lock-Up Agreements, each Locked-Up Shareholder has agreed, among other things, to (a) accept the Offer, (b) validly deposit or cause to be deposited under the Offer, and not withdraw or cause to be withdrawn, subject to certain exceptions, all of the Common Shares currently owned or controlled by such Locked-Up Shareholder, and (c) exercise all of the Options currently owned by such Locked-Up Shareholder and accept the Offer and validly deposit or cause to be deposited under the Offer, and not withdraw or cause to be withdrawn, the Common Shares issued upon the exercise of such Options. The aggregate number of Common Shares covered as of December 28, 2009 by the Lock-Up Agreements, including Common Shares receivable upon exercise of Options held by the Locked-Up Shareholders, is 9,429,541, or approximately 14.8% of the issued outstanding Common Shares.

The Locked-Up Shareholders have agreed not to withdraw their deposited Common Shares from the Offer during the term of the Lock-Up Agreement other than pursuant to the termination provisions of the Lock-Up Agreement described below, which include the right of Locked-Up Shareholders to terminate the Lock-Up Agreement in the event that the Support Agreement is terminated in accordance with its terms by the Issuer.

Each Locked-Up Shareholder has agreed, among other things, that it will (a) immediately cease and cause to be terminated any existing solicitation, discussion or negotiation, if any, with any person (other than the Offeror or its affiliates or representatives) with respect to any Acquisition Proposal (as defined below) or potential Acquisition Proposal, whether or not initiated by such Locked-Up Shareholder; (b) not, directly or indirectly, make, solicit, assist, initiate, encourage or otherwise facilitate any inquiry, proposal or offer regarding any Acquisition Proposal, engage in any discussions or negotiations regarding, or provide any information with respect to, or otherwise cooperate in any way with, or assist or participate in, facilitate or encourage, any effort or attempt by any person (other than the Offeror or its affiliates or representatives) to make or complete any Acquisition Proposal or accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking related to any Acquisition Proposal; (c) not option, sell, transfer, pledge, encumber, grant a security interest in, hypothecate or otherwise convey or enter into any forward sale, repurchase agreement or other monetization transaction with respect to any of the Common Shares currently owned or controlled by such Locked-Up Shareholder or issuable upon exercise of Options by such Locked-Up Shareholder, or any right or interest in such Common Shares; (d) not grant or agree to grant any proxy, power of attorney or other right to vote the Common Shares currently owned or controlled by such Locked-Up Shareholder or issuable upon exercise of Options by such Locked-Up Shareholder, or enter into any voting agreement, voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of securityholders or give consents or approval of any kind with respect to any of the Common Shares currently owned or controlled by such Locked-Up Shareholder or issuable upon exercise of Options by such Locked-Up Shareholder; and (e) not do indirectly that which it may not do directly by the terms of the Lock-Up Agreement or take any other action of any kind, directly or indirectly, which might reasonably be regarded as likely to reduce the success of, or delay or interfere with the completion of the Offer.

Page 8 of 19

“Acquisition Proposal” means, other than the transactions contemplated by the Support Agreement, any offer, proposal, expression of interest, or inquiry from any person (other than the Offeror or any of its affiliates) made after December 28, 2009 relating to: (a) any acquisition or sale, direct or indirect, of: (i) the assets of the Issuer and/or one or more of its subsidiaries that, individually or in the aggregate, constitute 20% or more of the fair market value of the consolidated assets of the Issuer and its subsidiaries taken as a whole; or (ii) 20% or more of any voting or equity securities of the Issuer or any of the subsidiaries of the Issuer whose assets, individually or in the aggregate, constitute 20% or more of the fair market value of the consolidated assets of the Issuer and its subsidiaries; (b) any take-over bid, tender offer or exchange offer for any class of voting or equity securities of the Issuer; or (c) a plan of arrangement, merger, amalgamation, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the Issuer or any of the subsidiaries of the Issuer whose assets, individually or in the aggregate, constitute 20% or more of the fair market value of the consolidated assets of the Issuer and its subsidiaries.

In addition to the foregoing covenants, each Locked-Up Shareholder has agreed that it will (a) promptly notify the Offeror of any proposal, inquiry, offer or request (or any amendment thereto) constituting, relating to or which could reasonably be expected to lead to an Acquisition Proposal, any request that it receives for discussions or negotiations relating to or which could reasonably be expected to lead to an Acquisition Proposal, any request that it receives for non-public information relating to the Issuer, any subsidiary of the Issuer or any mineral right or property of the Issuer or any request for access to properties, books and records of the Issuer or any subsidiary of the Issuer or for a list of the shareholders of the Issuer; and (b) not requisition or join in any requisition of any meeting of securityholders without the prior written consent of the Offeror, or vote or cause to be voted any of the Common Shares currently owned or controlled by such Locked-Up Shareholder or issuable upon exercise of Options by such Locked-Up Shareholder in respect of any proposed action by the Issuer or its shareholders or affiliates or any other person or group in a manner which might reasonably be regarded as likely to prevent or delay the completion of the Offer or have a material adverse effect in respect of the Issuer.

The Offeror has confirmed in the Lock-Up Agreements that it will make the Offer, or will cause the Offer to be made, in accordance with the terms and subject to the conditions in the Support Agreement. The Lock-Up Agreement may be terminated in respect of a Locked-Up Shareholder by written agreement of the Offeror and such Locked-Up Shareholder. The Lock-Up Agreement may also be terminated by the Offeror in respect of a Locked-Up Shareholder, subject to certain conditions, upon written notice if: (a) any Locked-Up Shareholder has not complied in any material respect with its covenants contained in the Lock-Up Agreement and such non-compliance is not curable or, if curable, is not cured by the earlier of the date that is five business days from the date of written notice of such breach and the business day prior to the expiry date of the Offer; (b) any representation or warranty of any Locked-Up Shareholder under the Lock-Up Agreement is untrue or incorrect in any material respect; (c) the Support Agreement has been terminated in accordance with its terms; or (d) any condition of the Offer is not satisfied or waived by the Offeror at or prior to the expiry time of the Offer.

The Lock-Up Agreement may be terminated by a Locked-Up Shareholder, subject to certain conditions, upon written notice if: (a) the Offeror has not made the Offer by 11:59 p.m. (Vancouver time) on February 1, 2010 (subject to extension in certain circumstances); (b) the

Page 9 of 19

Offer shall have expired or shall have been withdrawn in accordance with its terms; (c) the Offeror has not complied in any material respect with any covenant contained in the Lock-Up Agreement or if any representation or warranty of the Offeror herein is untrue or incorrect in any material respect and, in each case, such non-compliance or inaccuracy would reasonably be expected to prevent the completion of the Offer and is not curable or, if curable, is not cured by the earlier of the date that is five business days from the date of written notice of such breach and the business day prior to the expiry date of the Offer; (d) the Offer has been made and the Offeror has not taken up and paid for all Common Shares deposited under the Offer when required to do so in accordance with applicable law; or (e) the Support Agreement is terminated in accordance with its terms. Any termination of a Lock-Up Agreement by a Locked-Up Shareholder will only be effective with respect to such Locked-Up Shareholder.

Each Reporting Person reserves the right to change its plans and intentions at any time, as it deems appropriate. In particular, each Reporting Person may at any time and from time to time acquire Common Shares or securities convertible or exchangeable for Common Shares, dispose of Common Shares which it has acquired. Any such transactions may be effected at any time and from time to time subject to any applicable limitations of the Securities Act of 1933, as amended. Except as described herein, neither the Reporting Persons, nor, to the Reporting Persons’ knowledge, any of the Schedule I Persons has any present plans or proposals that relate to or would result in any of the actions described in Items 4(a) through (j) of Schedule 13D under Rule 13d-1(a). To the Reporting Persons’ knowledge, any of the Schedule I Persons may make the same evaluation and reserve the same rights.

The foregoing summaries of the Support Agreement, the Offer and the Lock-Up Agreements do not purport to be complete and are qualified in their entirety by reference to the complete text of the Support Agreement and the Form of Lock-Up Agreement attached hereto as Exhibit 99.2 and Exhibit 99.3, respectively, which are incorporated herein by reference.

Item 5. Interest in Securities of the Issuer

(a) and (b)

As of January 7, 2010, the Reporting Persons did not own any Common Shares. However, as of January 7, 2010, under the definition of “beneficial ownership” as set forth in Rule 13d-3 under the Exchange Act, the Reporting Persons may be deemed to have shared power to vote, direct the vote, dispose of or direct the disposition of (and therefore beneficially own), 9,429,541 Common Shares (including 2,005,000 Common Shares of which the Reporting Persons may acquire beneficial ownership within sixty days of December 28, 2009 through the exercise of Options held by the Locked-Up Shareholders), representing approximately 14.8% of the outstanding Common Shares as represented in the Support Agreement. Accordingly, the percentage of issued outstanding Common Shares that may be beneficially owned by the Reporting Persons is approximately 14.8%. The beneficial ownership of the 9,429,541 Common Shares referred to above that are subject to the Lock-Up Agreements is expressly disclaimed by each of the Reporting Persons.

(d)

Other than the Locked-Up Shareholders identified in Item 4 pursuant to the Lock-Up Agreements, to the best of Reporting Persons’ knowledge as of the date hereof, none of the Reporting Persons nor, to the Reporting Persons’ knowledge, any of the Schedule I Persons, has or knows any other person who has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of Common Shares referred to in this Item 5.
