“NSR Royalty” shall mean royalty that THE ACQUIRER shall be required to pay to THE TRANSFEROR as per section 2.4 of the Agreement and that shall be calculated according to the Net Smelter Returns and as per the Agreement and this Annex. Such royalty will only be payable if Commercial Production has been initiated.

_________________________

¹ This Exhibit is an English translation of Annex 1 to the Peru Purchase Agreement.

It is hereby agreed that payment of the NSR Royalty by THE ACQUIRER to the TRANSFEROR, does not include the Value Added Tax (IGV). In this sense, the amount of such IGV will be added to the NSR Royalty payment to be made by THE ACQUIRER, provided that THE TRANSFEROR will be obliged to deliver to THE ACQUIRER the corresponding invoices, issued in observance with any and all formalities required by law.

“Net Smelter Returns or NSR” shall mean the net amount, including all bonuses and subsidies that a given smelter, refinery or other buyer of Products pays to THE ACQUIRER; and that will result after making the deduction of all costs, expenses and charges paid or incurred in relation to the Products after concentration thereof (regardless of whether those costs had already been deducted by the acquirer of the Products or incurred in by THE ACQUIRER).

The costs referred to in the preceding paragraph include, without the following being limitative but merely referential, smelt, treatment and refining costs (including, without limitation, metal losses, impurity penalties and sampling and arbitration services); commissions for the sale of Products and costs related to their sale.

Such costs further include all types of taxes, royalties and/or customs and tariff duties, with the exception of income or similar taxes that THE ACQUIRER is required to pay for the extraction, treatment, transportation, storage, exportation and/or sale of the Products. They also include the costs incurred for the conversion of leachable solutions into cathodes and other similar goods, in addition to the costs incurred in the storage and transportation of the Products from the PROPERTIES to the smelter, refinery and/or final market where the Products are finally placed, or between any such places; and the costs incurred in buying insurance policies or paying freight associated with the Products during transportation or storage.

“Products” shall mean the ore resources extracted and recovered from the PROPERTIES, and the solutions, concentrates or cathodes obtained through leaching or solution extraction or other treatment of the ores extracted and recovered from the PROPERTIES.

The Products shall not include ores extracted outside the PROPERTIES’ area, neither solutions, concentrates nor cathodes obtained from mineralized material extracted outside the PROPERTIES’ area, whether placed in the PROPERTIES for leaching or other treatment, or conveyed to the PROPERTIES for treatment and/or storage.

Date of payment of NSR Royalties: Upon initiation of Commercial Production, payment of the NSR Royalty will be made by THE ACQUIRER to THE TRANSFEROR on a quarterly basis, within fifteen (15) calendar days following the date of delivery of the NSR Royalty’s payment settlements to which the following paragraph is referred to.

Within the ten (10) calendar days following the beginning of each quarter, THE ACQUIRER shall deliver to THE TRANSFEROR the NSR Royalty’s payment settlements with the calculation of the NSR Royalty determined in accordance with this annex. Attached to the aforesaid settlement, THE ACQUIRER will deliver to THE TRANSFEROR copies of the minerals’ sale settlements that may correspond, as well as any other information supporting the calculation of the NSR Royalties.

Method of payment: Payment of the NSR Royalties shall be made through the delivery of checks issued by THE ACQUIRER to the order of THE BENEFICIARY. The delivery of said checks will be made at the address established for those effects in the Agreement by THE BENEFICIARY. The payment of the NSR Royalties shall be deemed to have occurred upon receipt by THE TRANSFEROR of these checks.

Observations to the NSR Royalty payment: THE TRANSFEROR may observe the royalty’s payment settlements prepared by THE ACQUIRER within fifteen (15) calendar days following their receipt. If THE TRANSFEROR fails to make any observations to the NSR Royalty payment settlements forwarded by THE ACQUIRER within such fifteen (15) calendar days term, such payment settlements shall be deemed to have been accepted and approved.

Audit: If within the fifteen (15) days term referred to in section 4 of this annex, THE TRANSFEROR made any observations to the NSR Royalty payment settlements submitted by THE ACQUIRER, THE TRANSFEROR and THE ACQUIRER shall make their reasonable best efforts to reach an agreement regarding any differences which may have arisen between them.

If THE ACQUIRER and THE TRANSFEROR fail to reach an agreement within fifteen (15) calendar days following the date in which THE TRANSFEROR notifies its observations to THE ACQUIRER, the differences between such parties shall be submitted to a final and conclusive analysis of a titled public accountant experienced in the mining industry and that is acceptable for both parties. The expenses for the hiring of such consultant firm shall be initially assumed by THE TRANSFEROR.

The public accountant referred to in the preceding paragraph shall conduct an audit of all the documents supporting the NSR Royalty payment settlements subject to observations by THE TRANSFEROR, as well as of all such other information and/or documents as are necessary to that effect. The audit shall take place at the place to be designated by THE ACQUIRER for those effects and during the business hours of the latter.

If the audit reveals that the calculation of the NSR Royalties made by THE ACQUIRER is within a 2.5% range of the audit results, the cost of the audit shall be fully borne by THE TRANSFEROR. However, if the audit reveals that the calculation of the NSR Royalties made by THE ACQUIRER exceeds the 2.5% range of the audit results, THE ACQUIRER shall bear the costs thereof.

In any case, THE ACQUIRER shall pay THE TRANSFEROR – as an NSR Royalty payment – any shortfall determined by the audit, in which case the NSR Royalty payment settlements that had been subject to observations, will be amended in accordance to the

results of the audit. Upon completion of the audit and delivery of the results to THE ACQUIRER and THE TRANSFEROR, THE ACQUIRER shall pay, without any interests, any additional NSR Royalties that might have been determined by the audit. Such payment will be made by THE ACQUIRER within fifteen (15) calendar days of receipt of the audit.

However, if the audit determined that THE ACQUIRER paid NSR Royalties in excess of what is was really obliged to make, THE TRANSFEROR shall reimburse THE ACQUIRER the amount paid in excess by it (without interests) within fifteen (15) calendar days of receipt of the audit.

It is hereby expressly agreed that during the term in which the audit is being conducted, the term established in this annex for THE ACQUIRER to pay the NSR Royalties will not be suspended and, in this sense, THE ACQUIRER should continue compliance its payment obligation of the NSR Royalty when and as applicable

Sales to an Affiliate of THE ACQUIRER: Any smelter or refinery owned or controlled by THE ACQUIRER or any Affiliate thereof and/or of the entities controlling THE ACQUIRER, without exception, shall be deemed to be a treatment smelter or refinery for purposes of calculation of the Net Smelter Returns.

Net Smelter Returns on Products acquired by such refinery or smelter shall be calculated and determined in accordance with customary treatment smelting and refining practices, as if sold to such smelter or refinery by third parties. However, the amount of such Net Smelter Returns shall not be less of what THE ACQUIRER would have received if the Products had been sold to a smelter or refinery owned by a third party different from THE ACQUIRER or from of an Affiliate of the latter.

7.	Prudent operations: The ores (even after undergoing some type of treatment) extracted and recovered from the PROPERTIES, may be commingled with ores (even after undergoing some type of treatment) with a similar composition extracted from other mining properties other than the PROPERTIES.

All determinations required for the calculation of the Net Smelter Returns, including, without limitation, the metal grade of ores extracted from the PROPERTIES, and the metal grade or amount of metal recovered from such ores, shall be made by THE ACQUIRER in accordance with prudent engineering, metallurgy and cost accounting practices.
