Dear Sirs:

	Re: 	
      Exploration License No. 327-68 covering 3,610.6524
      hectares (ha) situated in the California-Vetas Mining
      District, Department of Santander, Republic of Colombia,
      Granted by Ministry of Mines and Energy (“MME”), Resolution
      No. 992013 on March 25, 1998 and modified by MME –
      IGEOMINAS Resolution No. 130 on February 10, 2006
      (“License 327-68”) 

	 	
       

	  	
      Exploration License No. 328-68 covering 99.4686
      hectares (ha) (Sector A – 43.12 ha; Sector B – 43.61 ha,
      Sector C – 11.3886 ha, Sector D – 1.35 ha) situated in
      the California-Vetas Mining District, Department of Santander,
      Republic of Colombia, Granted by MME, Resolution No. 992012 on
      March 25, 1998 (“License 328-68”) 

	 	
       

	  	
      Concession Proposal No. HDB-082 covering 7,000
      hectares (ha) situated in the California-Vetas Mining
      District, Department of Santander, Republic of Colombia,
      filed at IGEOMINAS-Bogota on April 11, 2006 (“Concession
      Proposal HDB-082”) 

We write to confirm our agreement with you, Jon Lehmann and
Allen Ambrose (together, the “Sellers”) for the sale to us, Wildcat Silver
Corporation (“Wildcat”) of a 100% interest in Licence 327-68, Licence 328-68 and
Concession Proposal HDB-082 (together, the “Property”), conditional upon and
subject to, among other things, release of the Sellers from an agreement dated
August 25, 2005 between the Sellers and Augusta Capital Corporation (“Augusta”)
for the purchase and sale of the Property.

It is understood that the purchase of the Property by Wildcat
is part of a series of transactions that includes (i) the transfer by Augusta of
all of the issued and outstanding shares of CVS Explorations Ltda. (“CVS”) owned
by it, to a corporation incorporated under the Business Corporations Act
(British Columbia) for that purpose (“BC Holdco”) and wholly-owned by Augusta;
(ii) the acquisition by Wildcat, though its wholly-owned subsidiary Ventana Gold
Corp. (“Ventana”), of all of the issued and outstanding shares of

	2 	EXECUTION COPY 

BC Holdco (and hence CVS) from Augusta (the “CVS Acquisition”);
(iii) a plan of arrangement between Wildcat and its security holders pursuant to
which all of the shares of Ventana will be distributed by Wildcat to the
shareholders of Wildcat on a one-for-one basis such that at the time of
completion of the Plan of Arrangement all of the outstanding shares of Ventana
will be held by the shareholders of Wildcat (the “Plan of Arrangement”); and
(iv) contemporaneously with completion of the Plan of Arrangement, the listing
of the common shares of Ventana for trading on the CNQ or such other exchange as
is acceptable to the Sellers.

The parties hereto now wish to enter into this Agreement in
order to set out the terms and conditions of the purchase and sale of the
Property and hereby agree as follows:

	1. 	
      Interpretation

	 	 	 	 
	1.1 	
      Capitalized terms used in this Agreement shall have the
      meanings ascribed to them in this Agreement.

	 	 	 	 
	2. 	
      Purchase and Sale

	 	 	 	 
	2.1 	
      Upon and subject to the terms of this Agreement, the
      Sellers agree to sell to Wildcat and Wildcat agrees to purchase from the
      Sellers, all of the Seller’s right, title and interest in and to the
      Property. The parties acknowledge however that the Property will be
      transferred by the Sellers to, and held by, CVS and that as a result CVS
      and BC Holdco shall, prior to or contemporaneously with Closing, become
      bound by this Agreement.

	 	 	 	 
	3. 	
      Purchase Price

	 	 	 	 
	3.1 	
      The purchase price for the Property is as
  follows:

	 	 	 	 
		(a) 	
      the sum of US$20,000, the prior receipt of which is
      acknowledged by the Sellers; and

	 	 	 	 
		(b) 	
      the sum of US$75,000, payable by Wildcat to the Sellers
      on the Closing in the proportion (as between the Sellers) as the Sellers
      may direct Wildcat prior to the Closing (the “Cash Payment”);
and

	 	 	 	 
		(c) 	
      the issuance and delivery as of the date of this
      Agreement by Wildcat of an aggregate of 3,000,000 Class “A” special
      warrants (the “Special Warrants”) on the following basis:

	 	 	 	 
			(i) 	
      2,250,000 Special Warrants will be issued to Jon Lehmann,
      or to whom Jon Lehmann may direct, and 750,000 Special Warrants will be
      issued to Allen Ambrose, or to whom Allen Ambrose may direct;

	 	 	 	 
			(ii) 	
      subject to Section 3.1(c)(iii), the Special Warrants will
      be exercisable by the holders thereof, without the payment of any
      additional consideration, for an aggregate of 3,000,000
  common

	3 	EXECUTION COPY 

	 		
      shares of Wildcat (the “Wildcat Warrant Shares”), at any
      time after the Closing Date until May 18, 2007;

	 	 	 
	 	(iii) 	
      Wildcat shall include the Special Warrants in the Plan of
      Arrangement such that upon completion of the Plan of Arrangement, the
      Special Warrants will be effectively exchanged, without the payment of any
      additional consideration by the holders thereof, for an aggregate of
      3,000,000 common shares of Ventana (the shares issuable upon exchange of
      the Special Warrants pursuant to this Section 3.1(c)(iii) are known herein
      as the “Ventana Warrant Shares”); and

	 	 	 
	 	(iv) 	
      the certificates representing the Special Warrants will
      contain the usual provisions as to adjustment for changes in share capital
      and capital reorganizations.

For the avoidance of doubt, Wildcat may
not proceed with the Plan of Arrangement unless Wildcat and Ventana provide
evidence to the Sellers that in connection with the Plan of Arrangement the
common shares of Ventana (including the Ventana Warrant Shares) have been
conditionally accepted for listing on the CNQ, or such other exchange as is
acceptable to the Sellers. 

	3.2 	
      Wildcat hereby grants to the Sellers, a non-transferable
      pre-emptive right (the “Wildcat Pre-Emptive Right”) in respect of every
      issuance of Equity Securities (as defined below) by Wildcat, such that the
      Sellers will have the right to purchase, in the aggregate, up to 10% of
      the Equity Securities issued by Wildcat during the period commencing on
      the date hereof and ending on the five year anniversary of such date (the
      “Pre-Emptive Right Period”) except that if the Special Warrants are
      included in the Plan of Arrangement pursuant to paragraph 3.1(c)(iii)
      above such pre-emptive right shall apply mutatis mutandis, as of
      completion of the Plan of Arrangement, in respect of every issuance of
      Equity Securities by Ventana (the “Ventana Pre-Emptive Right”) and the
      Wildcat Pre- Emptive Right will automatically terminate.

	 	 	 
		
      The Wildcat Pre-Emptive Right and the Ventana Pre-Emptive
      Right are hereinafter together referred to as the “Pre-Emptive Right” and
      for the purposes of this Section 3.2 Wildcat or Ventana, as applicable, is
      referred to as the “Corporation”.

	 	 	 
		
      The Pre-Emptive Right shall have the following terms and
      conditions:

	 	 	 
		(a) 	
      In the event that the Corporation wishes at any time
      during the Pre- Emptive Right Period to issue any Equity Securities from
      its treasury (and for greater certainty, such an issuance does not include
      the issuance of Equity Securities upon the exercise or conversion of any
      option or right issued pursuant to an employee stock option, stock
      appreciation, share purchase or similar plan, the exercise of share
      purchase warrants outstanding as of the date of this Agreement, the
      exercise of the Special

	4 	EXECUTION COPY 

	 		
      Warrants or Finder’s Fee Warrants or the issuance of
      Finder’s Fee Shares), the Corporation will give to the Sellers at least 10
      days’ written notice of such intention to issue Equity
  Securities.

	 	 	 
	 	(b) 	
      Such notice will describe the attributes of the Equity
      Securities being offered, including the total number of Equity Securities
      being offered for allotment and issuance (the “Offered
      Securities”), the subscription price per Offered Security, and the
      expected date of issuance of the Offered Securities.

	 	 	 
	 	(c) 	
      Upon receipt of an offer pursuant to paragraph (b), the
      Sellers will have the right to subscribe for up to an aggregate of 10% of
      the number of Offered Securities subject to such offer, in such proportion
      as between the Sellers as they may determine.

	 	 	 
	 	(d) 	
      Upon accepting the Corporation’s offer to subscribe for
      any Offered Securities, such accepting Seller will purchase the Offered
      Securities subscribed for at the subscription price for such Offered
      Securities as was set out in the notice, at the time of issuance of such
      Offered Securities by the Corporation.

	 	 	 
	 	(e) 	
      If the Sellers fail to give notice within the 10 days
      that they intend to purchase any or all of the Offered Securities which
      they are entitled to purchase pursuant to this Pre-Emptive Right, the
      Corporation will be entitle to issue all of the Offered Securities to any
      other party on the same terms or on terms no less favorable to the
      Corporation.

	 	 	 
	 	(f) 	
      This Pre-Emptive Right will not terminate as a result of
      the Sellers failing to exercise, at any time, this Pre-Emptive
    Right.

	 	 	 
	 	(g) 	
      For the purposes of this Section 3.2 “Equity Securities”
      means any security of any class of the Corporation and any rights,
      warrants, options or other instruments, entitling the holder, whether or
      not on a contingency, to acquire shares from the Corporation and any
      instruments convertible or exchangeable, whether or not on a contingency,
      into any of the foregoing.

	3.3 	
      In respect of the period ending on the two year
      anniversary of the Closing Date, Wildcat agrees to provide each of the
      Sellers with as much advance notice as is commercially reasonable of it:
      (i) ceasing to be a “foreign private issuer” for United States securities
      laws purposes; or (ii) ceasing to have its securities listed or posted on
      an exchange or market in Canada (including in particular the CNQ, the TSXV
      or the TSX). If the Special Warrants are included in the Plan of
      Arrangement pursuant to paragraph 3.1(c)(iii) above such covenant of
      Wildcat shall apply mutatis mutandis, as of completion of the Plan
      of Arrangement to Ventana and Wildcat will automatically cease to be bound
      by this Section 3.3.

	 	 
	3.4 	
      The Sellers acknowledge that Wildcat and/or Ventana may
      from time to time request that the references in this Agreement to
      December 15, 2006 be replaced

	5 	EXECUTION COPY 

with a later date. The Sellers hereby
agree that consent to such amendment shall not be unreasonably withheld or
delayed. Notwithstanding the foregoing the parties hereby agree that the Sellers
shall be under no obligation to consent to, and will not be considered
unreasonable to withhold consent to, any request by Ventana and/or Wildcat for
an extension beyond February 15, 2007.

      days of, completion of an Acquisition Ventana shall provide notice to the

      such agreement by entering into a voluntary pooling agreement in respect
      of the shares that are to be transferred on the same terms as are

This Agreement is made as of October 16, 2006, 

AMONG: 

JON LEHMANN, a businessman with
an office at 5712 East 25th

(the “Trustee”) 

AND: 

CVS EXPLORATIONS LTDA., a
Colombia corporation 

(“CVS”) 

AND: 

WILDCAT SILVER CORPORATION, a
British Columbia corporation 

(“Wildcat”) 

WHEREAS: 

	A. 	
      Pursuant to a letter agreement dated May 18, 2006 between
      Ventana Gold Corp. (“Ventana”), Wildcat Silver Corporation (“Wildcat”),
      the Trustee and Allen Ambrose and an agreement to be bound dated the date
      hereof among Ventana, Wildcat, CVS and 688287 B.C. Ltd. (together the
      “Acquisition Agreement”), the Trustee and Allen Ambrose (collectively, the
      “Sellers”) agreed to sell to Wildcat ((on the business that CVS will hold)
      and Wildcat agreed to purchase, all of the Sellers’ right, title and
      interest in and to License 327-68, License 328-68, and Concession Proposal
      HDB-082 (collectively, the “Property”);

	 	 
	B. 	
      Concurrently with the execution of this Agreement, the
      Trustee has submitted for registration with the Colombian Mining Registry,
      the documentation to effect the registration of the transfer of legal
      title to License 327-68 and License 328-68 from the Trustee to CVS, which
      transfer has not, as of the date hereof, been completed;

	 	 
	C. 	
      CVS and Wildcat have acknowledged that the Sellers have
      been advised by the Ministry of Mines (Colombia) that other applications
      for the granting of mineral rights associated with Concession Proposal
      HDB-082 have been filed (the “Prior Filings”) and although the Sellers are
      challenging such applications there can be no assurance that the Sellers
      will be successful and be awarded mineral rights associated with
      Concession Proposal HDB-082;

	- 2 - 	EXECUTION COPY 

	D. 	
      CVS and Wildcat have also acknowledged and agreed that
      Concession Proposal HDB-082 cannot be transferred until a determination of
      free area is made, said free area is granted and if and until the Prior
      Filings are discharged; and

	 	 
	E. 	
      Wildcat and the Trustee have agreed under the Acquisition
      Agreement, that if the Trustee shall hold any legal title to any of the
      Property after Closing other than, until and unless the Prior Filings are
      discharged, Concession Proposal HDB-082, he shall hold that interest in
      trust as bare trustee, for the benefit of CVS pursuant to the terms of
      this Agreement.

NOW THEREFORE THIS AGREEMENT WITNESSES that, in consideration
of the respective covenants and agreements contained herein, the consideration
provided for in the Purchase Agreement and for other good and valuable
consideration, the sufficiency and receipt of all of which are acknowledged, the
parties hereto agree as follows

      not otherwise defined herein shall have the meanings assigned thereto in
      the Acquisition Agreement.

	 	 	 
	2. 	
      Appointment. CVS hereby appoints the Trustee as
      its nominee, agent and bare trustee to hold legal title to License 327-68
      and License 328-68, and if and when the Prior Filings are discharged and
      any mineral rights associated with Concession Proposal HDB-082 are awarded
      to the Trustee (“Acquired Rights”) any Acquired Rights, for and on
      behalf of CVS in accordance with this Agreement, with the full power to
      manage and deal with License 327-68 and License 328-68, and any Acquired
      Rights, and to execute any instrument, document or encumbrance in respect
      of License 327-68 and License 328-68, and any Acquired Rights, for the
      sole benefit and account of CVS, all at the direction of CVS as principal
      and beneficial owner and in accordance with this Agreement and the Trustee
      hereby accepts such appointment.

	 	 	 
	3. 	
      The Trustee’s Agreements. The parties hereby
      acknowledge and agree that:

	 	 	 
		3.1 	
      the Trustee will hold the legal title to License 327-68
      and License 328-68, and any Acquired Rights, as nominee, agent and bare
      trustee for the sole benefit and account of CVS as principal and
      beneficial owner and the Trustee will have no equitable or beneficial
      interest in License 327-68 and License 328-68, and any Acquired Rights,
      and the equitable and beneficial interest in License 327-68 and License
      328-68, and any Acquired Rights, will be vested solely and exclusively in
      CVS;

	 	 	 
		3.2 	
      the Trustee will hold the legal title to License 327-68
      and License 328-68, and any Acquired Rights, as nominee, agent and bare
      trustee for the sole benefit and account of CVS as principal and
      beneficial owner, subject to and in accordance with the Acquisition
      Agreement, this Agreement and subject to the terms and conditions of any
      transfer, deed, lease, sublease, mortgage, debenture, security agreement,
      easement, right of way, licence, restrictive covenant or other instrument,
      document or encumbrances pertaining to the Property or any Acquired
      Rights;

	- 3 - 	EXECUTION COPY 

	 	3.3 	
      the Trustee will, upon the direction of CVS, deal with
      License 327-68 and License 328-68, and any Acquired Rights, and do all
      acts and things in respect of License 327-68 and License 328-68, and any
      Acquired Rights, at the expense of and as directed by CVS from time to
      time, but only to the extent that such directions do not conflict with the
      terms of License 327-68, License 328-68 and/or any Acquired Rights or any
      applicable laws.

	4. 	
      Reimbursement of Expenses. Any payments or
      disbursements made by the Trustee in respect of the Property or any
      Acquired Rights in accordance with this Agreement will be made as the
      agent of and for the account of CVS, as principal, and CVS will reimburse
      the Trustee for any amount reasonably expended by the Trustee in
      connection with the Property or any Acquired Rights. All mortgages,
      debentures or security agreements in respect thereof, are the liabilities
      of CVS as principal and the Trustee in incurring or granting the same is
      acting only as agent for CVS. The Trustee will not be entitled to any
      remuneration or any revenue or profit in respect of the Property or any
      Acquired Rights for acting as nominee, agent and bare trustee under this
      Agreement.

	 	 	 
	5. 	
      Indemnity by Wildcat. Wildcat agrees to indemnify
      and save harmless the Trustee against any and all liability, loss, cost,
      action, claim or expense which he may suffer or incur or which may be made
      against him by any person, firm, corporation, or any governmental
      authority, arising out of or in any way connected to or resulting from the
      Trustee’s holding of title to or dealing with the Property or any Acquired
      Rights including any failure by CVS to reimburse and pay the Trustee under
      section 4 hereof.

	 	 	 
	6. 	
      Time Limitation. The powers herein conferred on
      the Trustee will not extend beyond the expiration of 80 years from the
      date of execution and delivery of this Agreement, unless
renewed.

	 	 	 
	7. 

	
      Term. The term of this Agreement shall commence on
      the date first written above and shall continue until the earlier of (a)
      the date that title to each of Licenses 327-68 and 328-68 and any mining
      rights that may be derived from Concession Proposal HDB-82 have been
      transferred to CVS and inscribed in the National Mining Registry or, in
      the case of Concession Proposal HDB-82, such transfer has “failed”; and
      (b) the five year anniversary of the date hereof. For the purposes of this
      section the transfer of any mining rights that may be derived from
      Concession Proposal HDB-82 will be deemed to have “failed” upon the
      earlier of (i) the expiration of the time prescribed by applicable
      Colombian law for appealing a refusal by the National Mining Registry to
      register the requested transfer, without the making of any appeal; (ii)
      the exhaustion of all appeals of such refusal by the National Mining
      Registry to register the requested transfer; or (iii) the agreement of the
      Trustee and CVS (in writing) that further legal proceedings are unlikely
      to have a positive outcome and no further efforts are warranted.
      Notwithstanding the foregoing, the parties agree that prior to any
      termination of this Agreement pursuant to subparagraph (b) hereof, the
      parties shall discuss with each other the effect of such termination on
      the ownership of

	- 4 - 	EXECUTION COPY 

		
      the Property with a view to arriving at an alternative
      arrangement regarding legal and beneficial ownership thereof that reflects
      the intent of the Acquisition Agreement.

	 	 
	8. 	
      Notices. Any notice given pursuant to or in
      connection with this Agreement will be in writing and delivered personally
      to the party for whom it is intended to be addressed at the address of
      such party last known to the other party.

	 	 
	9. 	
      Further Assurances. The Trustee will perform all
      such other acts and things and execute all such other documents as are
      necessary or desirable in the reasonable opinion of CVS and Wildcat to
      evidence or carry out the terms of this Agreement.

	 	 
	10. 	
      Governing Law. This Agreement and all matters
      arising under it will be governed by and construed in accordance with the
      laws of British Columbia which will be deemed to be the proper law of this
      Agreement and the courts of British Columbia will have the non-exclusive
      jurisdiction to entertain and determine all claims and disputes arising
      out of or in any way connected with this Agreement and the validity,
      existence and enforceability of this Agreement.

	 	 
	11. 	
      No waiver. No failure or delay on the part of
      either party in exercising any right, power, or privilege under this
      Agreement will operate as a waiver thereof, nor will any single or partial
      exercise of any right, power or privilege preclude any other or further
      exercise thereof or the exercise of any other right, power or privilege.
      Except as may be limited by this Agreement, any party may, in its sole
      discretion, exercise any and all rights power remedies and recourses
      available to it under this Agreement or any other remedy available to it
      and such rights, powers, remedies and recourses may be exercised
      concurrently or individually without the necessity of making any
      election.

	 	 
	12. 	
      No Derogation. This Agreement shall in no way
      limit or derogate from, shall not merge with and is without prejudice to
      the covenants, agreements, representations, warranties, indemnities and
      obligations of the parties hereto contained in the Acquisition Agreement,
      all of which shall continue in full force and effect in accordance with
      the terms thereof. In the event of any conflict or inconsistency between
      this Agreement and the Acquisition Agreement, the Acquisition Agreement
      shall prevail.

	 	 
	13. 	
      Amendment. This Agreement may be altered or
      amended only by an agreement in writing signed by the parties
    hereto.

	 	 
	14. 	
      Enurement. This Agreement shall enure to the
      benefit of and be binding upon the parties and their respective heirs,
      representatives, successors and assigns.

IN WITNESS WHEREOF this Agreement has been executed the day and
