CLAIMS FROM MINERA SANDIA

(A)	If Minera Sandia does not make some of the payments set forth in subsection (B) of clause 2 (two) hereof on the respective dates stated therein, Suaqui Grande shall provide to Minera Sandia a written notice indicating that it has 30 (thirty) additional calendar days to make such payments or to prove to Suaqui Grande that it already has made such payments, after which term, in case such payment has not been made or if Minera Sandia does not prove to Suaqui Grande that it actually has made such payment, the Option and this agreement shall be deemed terminated automatically and without legal effects whatsoever, without any further liabilities for Minera Sandia than those agreed to herein.

(B)	If Suaqui Grande considers that Minera Sandia has not complied some of its obligations which it acquires hereunder, other than those set forth in subsection (A) of this clause, Suaqui Grande shall notify Minera Sandia in writing that it has thirty (30) calendar days to begin to remedy the non-compliance or to prove to Suaqui Grande that it has not failed to comply, at the end of which period, if it has not begun to remedy the non-compliance or begun to remedy it, or if Minera Sandia has not proven to Suaqui Grande that it did not fail to comply, then, the Option and this agreement shall be deemed terminated automatically and without legal effects whatsoever, without any further liabilities for Minera Sandia than those agreed to herein. The notice of non-compliance shall include sufficient circumstances, so that Minera Sandia may take the pertinent corrective measures or remedies, according to the nature of the attributed failure to comply.

(D)

Suaqui Grande shall not be entitled to file a complaint against, or take, or petition any other legal measure against Minera Sandia, without previously proceeding as established in the two foregoing paragraphs of this clause, as may be applicable. As of now, the parties agree that the fact that Suaqui Grande exhausts the mechanism established in the two foregoing shall be deemed, for all legal purposes, a necessary assumption as regards the lawfulness of any action or any other type of measure or legal petition which Suaqui Grande intends to inchoate or file against Minera Sandia.

ACT OF GOD OR EVENT OF FORCE MAJEURE

The term for the compliance of the obligations which the parties acquire pursuant hereto, the Term of the Option, and the duration of this agreement shall be suspended and shall be kept so, during the entire duration of the act of God or event of force majeure, without it therefore being deemed that the parties have failed to comply said obligations or that they have decided not to exercise the Option, or that this agreement has been breached. For the purposes of this subsection, the following, by way of illustration, respectively constitute acts of God or events of force majeure: strikes, blockades, closing of or obstacles on roads; lockouts, taking possession of facilities, offices, or other property of Minera Sandia o its contractors or subcontractors thereof; protests, demonstrations, or other types of actions by environmentalist groups or

Mining Agreement
Minera Suaqui Grande S. de X.X. de C.V. and
Minera Sandia, S.A. de C.V.
June 13, 2009

persons or Indian or ethnic groups or persons or non governmental organizations, or neighbors or ejidos or ejido members; expropriations, seizures or taking possession of property ordered and executed or tolerated by any level or jurisdiction of government authorities; laws, regulations; decrees, orders for the suspension of activities or closures, or other types of governmental acts, including, but without being limited to acts of environmental authorities, judgments; not having obtained a license, permit, agreement, authorization, consent, right of access or right of way or delay in obtaining such; prohibition for exporting ores decreed by the Mexican government; decree of ruinous taxes or contributions or non-tariff measures that make producing and exporting ores unprofitable, at the sole opinion of Minera Sandia; unavailability of materials or means of transportation; impossibility or insurmountable difficulty, in Minera Sandía’s sole opinion, to enter and exit the Surface Land, and other events of a similar or analogous nature. The term for the compliance of the obligations that Minera Sandia acquires pursuant hereto, the Term of the Option and the duration hereof shall be deemed automatically extended for a period of time equal to that of the duration of the cause of suspension stipulated in this clause, without prejudice of Minera Sandia’s right to terminate it in advance. No act of God or event of force majeure shall release Minera Sandia from its obligation to pay the mining rights for the Concessions, all during the Term of the Option, unless, any or some of these obligations can not be complied since said rights can not or have not been received by the banks, authorities, institutions, or agencies that should receive them, or for not being able to pay due to any cause, reason or circumstance not attributable to Minera Sandia.

The party which takes this clause as its basis shall take all steps and shall execute all actions reasonably possible to eliminate the act of God or event of force majeure or its effects and, if possible, shall comply with the obligations it acquires hereunder, to the degree in which it is practical. None of the parties shall have the obligation to negotiate or compromise with the persons, groups, organizations, or authorities that give rise to the events set forth in this clause, or the obligation to challenge state, governmental or administrative acts which also constitute events of force majeure pursuant to this clause, or the obligation of complying with what has been agreed to herein, if an event of force majeure or act of God renders such compliance impossible.

The lack of possibility to comply due to an event of force majeure or act of God shall release the parties, while the cause or event of force majeure or act of God persists, except when the act of God is caused by the lack of funds of the party of reference.

The establishment, imposition, registration, continuation, or subsistence of a Lien on any of the Concessions or any of the Lots or part of any of the Lots or any of the Related Agreements or on any of the properties or rights of Suaqui Grande subject to this agreement shall not be deemed an event of force majeure or an act of God and therefore, shall not excuse Suaqui Grande’s failure to comply.

(B)	Suaqui Grande shall only be entitled to assign, promise to assign, lien, option, or enter into contracts and agreements in relation to some or all of the rights and obligations resulting hereunder or in relation to any of the mining concessions, agreements, permits, properties, or rights object hereof (prior to these being acquired by Minera Sandia) or to provide as security or to create or impose a Lien on any of said rights or obligations, or mining concessions, agreements, permits, properties or rights object hereof (prior to these being acquired by Minera Sandia), if it has Minera Sandia’s previous, express and written agreement and none of these acts shall be opposable to Minera Sandia if the latter did not consent to them as agreed to in this section.

(C)	Minera Sandia may provide this agreement and the rights resulting hereunder as security and any further or additional consent or agreement from Suaqui Grande shall not be required for such purpose and hereby, Suaqui Grande irrevocably grants its agreement and consent thereto.

(B)	Within a 180 (one hundred eighty) calendar day term following the effective date of termination of the Option and this agreement by the up-date of any of the hypotheses set forth in paragraph (A), subsections (i) one and (ii) (two) of this clause, Minera Sandia may and shall remove all the facilities, machinery, equipment, and other properties owned by Minera Sandia and by whoever has worked for the latter, which are still on any of the Lots, except for those facilities that should remain thereon pursuant to the Mining Law and its Regulation. The properties which Minera Sandia does not remove from the Lots within the term set forth in this paragraph shall become Suaqui Grande’s property and the latter shall not have to pay Minera Sandia for them, unless Minera Sandia has been unable to remove them due to acts of God or events of force majeure or acts, omissions, liabilities, or obligations attributable to Suaqui Grande or which are Suaqui Grande’s or attributable to persons acting on behalf or by instructions, or to the benefit of Suaqui Grande.

(C)

If this agreement is terminated due to any of the hypotheses set forth in paragraph (A), subsections (i) (one) and (ii) (two) of this clause, Minera Sandia shall deliver to Suaqui Grande within a 90 (ninety) calendar day term following the date in which Suaqui Grande may request it in writing, a report describing all the works performed on the Lots, limited to matters of fact, exclusively together with copies of maps showing the location of samples, a copy of the drill assay logbook, a copy of the assay results, and other technical data compiled by Minera Sandia in relation to the Lots, but without any guaranty that the reports, maps, assays and technical data shall be appropriate for any end or purpose whatsoever and without any guaranty as regards their accurateness and completeness.

ESTABLISHMENT OF COLLATERAL

(A)	If Minera Sandia decides to exercise the Option and on the date on which the Final Agreement shall be formalized and delivered, any of the Concessions, any of the Related Agreements, or any of the Permits are subject to any Lien or any debt resulting from Suaqui Grande’s acts, omissions, liabilities, or obligations, Minera Sandia may pay the amounts or comply with the obligations or satisfy the liabilities that have given place to the Liens or the debts of reference, which shall be charged to the amounts set forth in paragraph (B) of clause 2 (two) which still have not been paid to Suaqui Grande and, in a given case, pay the amounts owed or comply with the obligations or satisfy the liabilities that must be paid, complied or satisfied in excess of said amounts set forth in paragraph (B) of clause 2 (two) that still have not been paid to Suaqui Grande, and in a given case, to pay the amounts owned or to comply with the obligations or to satisfy the liabilities that should be paid, complied or satisfied in excess of said amounts set forth in paragraph (B) of clause 2 (two), in which case, the Option shall be deemed exercised and Suaqui Grande shall pay or reimburse Minera Sandia what it had paid or complied or satisfied in excess of said amounts set forth in paragraph (B) of clause 2 (two), plus lawful interests. The expenses or disbursements that Minera Sandia would cause to pay, comply, or satisfy Suaqui Grande’s amounts, obligations, or liabilities under the circumstances set forth in this subsection, plus lawful interests shall also be borne by Suaqui Grande, and charged to the amounts set forth in paragraph (B) of clause 2 (two).

(B)	Suaqui Grande commits to reimburse Minera Sandia for the amounts it already had paid Suaqui Grande from among those set forth in paragraph (B) of clause 2 (two) hereof, plus lawful interests, if, on the date on which the Final Agreement should be formalized and delivered, any of the Concessions or any of the Related Agreements or any of the Permits are subject to any Lien or debt resulting from Suaqui Grande’s acts, omissions, liabilities, or obligations and therefore, Minera Sandia decides not to formalize and deliver the Final Agreement, in which case, the Option shall be deemed not exercised. Suaqui Grande shall also pay to Minera Sandia the expenses or disbursements, plus lawful interests, made by Minera Sandia to document, notarize, and notify its decision of not formalizing and delivering the Final Agreement under the circumstances set forth in this paragraph.

(C)	To assure the compliance of the obligations it acquires under paragraphs (A) and (B) of this clause, irrevocably Suaqui Grande establishes in favor of Minera Sandia, first collateral on the titles of the Concessions and the Related Agreements that qualify as personal property pursuant to the law. This collateral
