(“the Customer”)

and to refine the material from the Customer’s El Gallo mine in Sinaloa, Mexico referred to in Clause 1 (“the Material”) at the Refiner’s refinery at Salt Lake City, Utah, USA (“the Refinery”) and the Customer agrees to deliver the Material to the Refiner for refining on the terms and conditions of this agreement (“this Agreement”). The Refiner and the Customer are referred to in this Agreement as a “Party” or together as the “Parties”.

1. Material and Quality

1.1. “Material” means gold/silver Doré in the form of bars, having the following approximate assays:

Gold - approximately 50%; in the range of 45-55%

Silver - approximately 50%; in the range of 45-55%

1.2. Each bar shall:

(a) weigh no more than 25 kgs; and

(b) be suitable for direct melting and sampling.

1.3. Customer represents, warrants, and covenants with the Refiner that the Customer shall have the legal right to deliver the Material to the Refiner as provided in this Agreement and to receive delivery of the Recoverable Metals (as defined below) from the Refiner as provided in this Agreement.

1.4. Refiner represents, warrants, and covenants with the Customer that Refiner shall perform the services required to be performed by Refiner pursuant to this Agreement (the “Services”) with reasonable skill and care in accordance with the generally accepted industry standards for refiners providing similar services.

2. Quantity

2.1. The Customer shall deliver to the Refiner for refining all the production of Material from the Customer’s El Gallo Mine (the “Mine”), estimated to be approximately 1,800 ounces of Material, available as one shipment every two weeks throughout the term of this Agreement.

2.2. Each shipment of Material by the Customer to the Refiner under this Agreement (“Shipment”) will consist of no less than 1,000 ounces of Material.

3. Delivery

The Customer shall deliver the Material to the Refinery, free of all charges on the Refiner with full all risks insurance covered by the Customer on a door to door basis. The Material will be securely packaged and sealed, with the unique number of each seal detailed on the bar list that accompanies each shipment. Each bar shall be marked to correspond with the bar list.

Each Shipment will have full and complete documentation to permit correct importation into the United States, including but not limited to a Commercial Invoice and a detailed bar list. The Commercial Invoice shall include the following information with respect to the Shipment: (a) the number of Doré bars, (b) the weight of each Doré bar and of the total Shipment, and (c) the provisional assay for each Doré bar and the total gold and silver content of the Shipment.

4. Risk of Loss

4.1. Risk of loss and damage to the Material shall pass from the Customer to the Refiner upon signature for the Material by the Refiner at the Refinery.

4.2. In the event of the loss of a Shipment prior to sampling by the Refiner, the value of such loss shall be based on the weight and assays provided by the Customer to the Refiner in the Commercial Invoice or bar list included with the Shipment; provided, however, that if the loss occurs after the Refiner has weighed the Material upon arrival in accordance with Appendix 1, Refiner’s weight shall be used.

4.3. In the event of the loss of a Shipment after sampling by the Refiner, the value of such loss shall be based on the average of the assays conducted by each of the Customer and the Refiner.

4.4. The value of each Shipment for insurance purposes shall be as set out in the Commercial Invoice or bar list.

5. Weighing, Sampling and Assaying

Weighing, sampling and assaying will be carried out in accordance with the procedures set out in Appendix 1 to this Agreement.

6. Recoverable Metals

The Refiner shall recover and credit the Customer with the following percentages of the final agreed assayed gold and silver contents of refined Material from each Shipment (“the Recoverable Metals”)

Gold |  | 99.75% of assayed content
Silver |  | 99.00% of assayed content

7. Metal Availability

Delivery of the Recoverable gold and silver from each Shipment will be made as directed by the Customer pursuant to Clause 8 no more than fifteen (15) working days after receipt of the Material by the Refiner at the Refinery if requested in Salt Lake City, and no more than fifteen (15) working days after receipt of the Material by the Refiner at the Refinery if requested in London, subject in each case to the assay results being within the splitting limits set forth in Appendix 1 to this Agreement (“the Metal Availability Date”). If the assay results are submitted to umpire as set forth in Appendix 1 to this Agreement, an initial settlement shall be made on the dates specified in this Clause 7 based on the lower of the two assays, and shall be adjusted based on the umpire’s results within one (1) working day after receipt of the umpire’s assay results.

For the purposes of calculating Metal Availability Dates, the five Business Days immediately prior to the Refiner’s annual inventory listing date shall be excluded. The Refiner undertakes to provide the Customer with written notice of its annual inventory listing date. The Customer may reorganise the timing of their deliveries to minimise the impact of this period, provided it gives the Refiner two weeks’ notice of its intent to do so.

8. Settlement as Metal Account Credit

8.1 Customer shall instruct the Refiner, in writing prior to receipt of the Shipment concerned, to deliver the Recoverable Metals on or after the Metal Availability Date in accordance with the following options:

8.1.1 Customer may instruct the Refiner to credit the Recoverable Metals to the Customer’s unallocated metal account with the Refiner and to await further instructions from the Customer, or

8.1.2 Customer may instruct the Refiner to transfer the Recoverable Metals to the unallocated loco Salt Lake City account of a third party with an account in good standing, or

8.1.3 Customer may instruct the Refiner to transfer the Recoverable Metals to the unallocated loco London account of the Customer with a member of the London Bullion Market Association, or

8.1.4 Customer may instruct the Refiner to transfer the Recoverable Metals to the unallocated loco London account of a nominated third party held with a member of the London Bullion Market Association.

8.2 In the case of Clauses 8.1.2, 8.1.3 and 8.1.4 above, Customer will have the right, prior to receipt of the Shipment concerned, to give irrevocable instructions, in writing, to the Refiner that the Recoverable Metals are to be so transferred and to request the Refiner to confirm, in writing to the nominated recipient that it is in receipt of such instructions from the Customer and will act irrevocably in accordance with them. For the avoidance of doubt, any such instructions remain subject to the terms of this Agreement, including Section 9.4 hereof.

8.3 Customer will provide fourteen (14) days written notice, prior to receipt of the Shipment concerned, to the Refiner to switch locations for the metal credits. In addition, any changes to the settlement option being used must be notified to the Refiner prior to receipt of the Shipment concerned.

8.4 In the event Customer elects to sell the payable gold and/or silver contents of the Material to the Refiner, it may price these with the Refiner on or after the Metal Availability Date referred to in Clause 7, using a price basis agreed with the Refiner.

8.5 Customer may set off or withhold payment of money due to Refiner until all amounts of money or Recoverable Metals due from Refiner to Customer have been paid or delivered. Interest shall accrue on late payments or deliveries at 3% per annum above the Fed Funds daily rate from time to time from the date of the payment or delivery was due to the date of payment or delivery (before and after judgment). Refiner acknowledges that its business dealings with the Customer constitute a single

continuous transaction, notwithstanding the issuance of separate purchase orders, acknowledgments, or similar documents from time to time.

9. Charges

The Customer shall pay the Refiner’s charges as follows:

9.1. Treatment:

US$0.75 per troy ounce of Material received.

9.2. All charges due to the Refiner in accordance with this Clause 9 shall be invoiced in United States dollars by the Refiner at the time of delivery of the Recoverable Metals as provided in Clause 7, and shall be payable by the Customer within fifteen (15) working days of receipt of the Refiner’s invoice therefore in accordance with the Refiner’s payment instructions.

9.3. The Refiner may setoff or withhold delivery or payment of metal or money due to Customer until all amounts due from Customer to Refiner have been paid. Interest shall accrue on late payments at 3% per annum above the Fed Funds daily rate from time to time from the date of invoice to the date of payment (before and after judgment). Customer acknowledges that its business dealings with Refiner constitute a single continuous transaction, notwithstanding the issuance of separate purchase orders, acknowledgments, or similar documents from time to time.

10. Deleterious Elements

10.1. The Customer shall notify the Refiner in advance of delivery if any Material proposed to be sent to the Refiner contains any of the deleterious elements referred to in this clause. The Customer shall regularly sample the Doré on site and send such sample to the Refiner on occasion to check the levels of deleterious elements in the sampled lot. The Refiner and Customer shall communicate to ensure that each lot has acceptable levels of deleterious elements before leaving the Mine.

10.2. Unless prior written agreement is given the Refiner may reject any Material containing in excess of the maximum limits of deleterious elements set out herein (defined, for each element, as the level just below the level that is “to be agreed prior to shipment”). The Refiner shall have no liability for such rejection. The Customer shall, at its expense, remove any rejected Material from the Refinery.

10.3. The Refiner may make additional charges as set out in Clause 10.4 if the free limit in respect of any element referred to below is exceeded. The Refiner will notify the Customer of such additional charges when the nature and proportion of any such element is determined.

Appendix 1

WEIGHING AND SAMPLING PROCEDURE FOR

GOLD AND SILVER DORÉ

1, General

Weighing and sampling will be carried out at Johnson Matthey Inc., Salt Lake City, USA works. The sampling will be final for all contractual purposes.

The Customer has the right to be represented at these operations at its own expense, either by use of an agreed independent representative company or an employee of the Customer.

2. Weighing

2.1 On arrival of the Material, visual inspection of the seals will take place and the gross weight of the Material and packing will be determined and compared with the advised gross weight. Any difference in excess of 1% (one percent) of the gross weight as stated in the Commercial Invoice between the gross weight as stated in the Commercial Invoice and the gross weight determined by the Refiner, or the detection of damaged packaging, will be reported to the Customer or its representative immediately.

In the case of a representative not being present, the Material will be placed in a secure vault pending arrival of the representative, or a decision to proceed or otherwise, in writing, from the Customer.

2.2 The net weight of the Material shall be determined by removing the Material from the packing and individually weighing each Dore bar on a Class II balance having a tolerance of +/-1 (one) gram.

In the case of a difference greater than 0.2% of the net weight of any Dore bar as stated in the Commercial Invoice between the net weight of such Dore bar as stated in the Commercial Invoice and as determined by the Refiner, such Dore bar will be held in a secure vault pending advice from the Customer to proceed or otherwise, in writing.

3. Melting

3.1 Melts of up to 3,000 ounces troy will be covered with charcoal/borax to prevent oxidation and raised to a temperature of 100 o C above the melt point of the material.

3.2 When the melt is completely molten and has been allowed to stir vigorously by the induced current, the flux cover will be removed and reserved.

3.3 Pin samples will be taken from the molten mass, by use of a vacuum tube, as follows:

2 samples for the Refiner to analyse,

2 samples to be held by the Refiner in case of a reserve analysis or recourse to an independent third party, and

1 sample for the Customer or its representative.

3.4 The agreed net weight will be arrived at by adding the weight of the after melt bars together with any samples retained by the Refiner. This will be the final after melt weight. Any samples that the Customer or its representative takes will not constitute payable settlement weight.

4. Slag Sampling

The slags and pot scrapings will be remelted and any grain bars produced during this operation will be weighed and added to the final after melt weight. Any grain bars weighing in excess of 5 troy ounces will be assayed separately. All slags will be kept until agreement of assays and then disposed of.

5. Assaying and Settlement Procedure

Assaying will be by the classical fire assay method.

5.1 The Refiner and the Customer will exchange assays by registered mail, on a date agreed in advance. The day after the date on which the Parties have agreed to make the exchange, the Refiner and the Customer will exchange said assays by e-mail, telephone or fax.

The splitting limit for gold shall be 0.05%

The splitting limit for silver shall be 0.20%.

If the assay results exchanged are within the splitting limits described, the arithmetic mean of the results will be the settlement assay

If the exchange assays are outside the splitting limits and agreement cannot be reached, either Party may request umpire analysis by one of the independent assayers listed in Appendix 2 to this Agreement. The independent assayers shall act as an expert and not an arbitrator. The Party whose assay is closer to the umpire shall be the final assay. The cost of the umpire assay shall be borne by the Party whose assay is further from the umpire assay.

In the event that the umpire assay equals the arithmetic mean of the assays, the umpire assay shall be the final assay and the cost of such umpire assay shall be borne equally by the Parties.
