Rio Salado Parkway, Suite 900, Tempe, AZ USA 85281 (“Big Bear” or the “Company”) whereby GPMUS will grant Big Bear an exclusive option (“Purchase Option”) to purchase one hundred percent (100%) of GPMUS’s interests in the Lewiston properties located in the Lewiston Mining District, Fremont Co., Wyoming and as described more specifically on Attachment A (collectively the “Lewiston Property”), on the terms and conditions set forth below.

Term. This Option Agreement and Purchase Option will become effective as of the last date signed by the parties below (“Effective Date”) and will expire upon the occurrence of: (i) Big Bear’s exercise of its Purchase Option and completion of earn-in deliverables set out in Paragraph 6 below prior to the fourth (4th) anniversary of the Effective Date and GPMUS’s conveyance and assignment of one hundred percent (100%) of its interests in the Lewiston Property to Big Bear; or (ii) Big Bear’s relinquishment of its Purchase Option any time prior to the fourth (4th) anniversary of the Effective Date; or (iii) the fourth (4th) anniversary of the Effective Date if Big Bear has neither exercised nor relinquished its Purchase Option prior to that anniversary.

Option Payment. As full and sufficient consideration for receipt of the Purchase Option, Big Bear shall provide GPMUS with a non-refundable cash deposit of ten thousand dollars (US $10,000) within five (5) business days of receipt of GPMUS’s written execution of this Option Agreement (“Option Payment”).

Due Diligence. Upon delivery of the Option Payment to GPMUS, a forty-five (45) day period (the “Due Diligence Period”) shall commence for Big Bear to conduct normal and customary due diligence at its sole discretion including physical inspection of the Lewiston Property assets. GPMUS will promptly make available to Big Bear, all information pertaining to the Lewiston Property (including without limitation all agreements, leases, drill core, copies of all reports, maps, assay results and other relevant technical data) compiled by, prepared at the direction of, or in the possession of GPMUS with respect to the Lewiston Property and not previously furnished to Big Bear.

Access. During the term of this Option Agreement, to the fullest extent of its rights to do so, GPMUS grants Big Bear full access to the Lewiston Property, including any rights of ingress and egress which GPMUS enjoys through nearby or adjacent properties, as well as the exclusive right to conduct mineral exploration and development activities on and under the Lewiston Property.

5.	Purchase Option Election. Upon Big Bear’s completion of due diligence, Big Bear may proceed, at its sole discretion, either to:

Elect in writing to relinquish its Purchase Option with no further obligation owed to GPMUS except those obligations set forth in that certain Confidentiality Agreement dated December 6, 2010 between the parties (“Confidentiality Agreement”)and remediation of any areas disturbed by Big Bear during its due diligence; or

Elect in writing to exercise its Purchase Option by performing the earn-in deliverables outlined in Paragraph 6 below, in which event the non-refundable ten thousand dollar ($10,000) deposit will be applied towards the initial cash payment due to GPMUS before the first anniversary of the Effective Date under Paragraph 6(a)(i) below

provided that prior to electing to exercise its Purchase Option by performing the earn-in deliverables, the parties shall have received the consents required under the Mining Leases described in Attachment A (the “Underlying Agreements”), as well as confirmation from the lessors that the Underlying Agreements are in good standing. GPMUS will use reasonable commercial efforts to obtain such consents and confirmations prior to the expiry of the Due Diligence Period.

6.	Exercise of Purchase Option. Big Bear’s exercise of its Purchase Option shall consist of performance of the earn-in deliverables set out herein, subject to Big Bear’s right to accelerate its performance of these deliverables at its sole discretion:

Tender to GPMUS a total non-refundable cash payment of two hundred thousand dollars (US $200,000), payable in the following increments: (i) forty thousand dollars ($40,000) consisting of the ten thousand dollar ($10,000) deposit previously paid and an additional thirty thousand dollars ($30,000) payable on or before the first anniversary of the Effective Date; (ii) forty thousand dollars ($40,000) payable on or before each of the second and third anniversaries of the Effective Date; and (iii) the final eighty thousand dollars ($80,000) payable on or before the fourth anniversary of the Effective Date; and

Tender to GPMUS shares of Big Bear stock totaling one million one hundred thousand (1,100,000), delivered per the following schedule: (i) five hundred thousand (500,000) shares at the end of the forty-five (45) day due diligence period; and (ii) two hundred thousand (200,000) shares on each of the first, second, and third anniversaries of the Effective Date with such shares being subject to a six month trading restriction and applicable stock exchange rules, provided that if GPMUS cannot sell any of the shares due to Big Bear ceasing to make timely reports required by the US Securities and Exchange Commission, it shall be a condition to the exercise of the option that Big Bear repurchase the Shares not capable of being sold from GPMUS for $0.15 per share; and

Incur exploration expenditures on the Lewiston Property totaling one million dollars (US $1,000,000), including evaluation and delineation of gold resources, but exclusive of (A) any charges for overhead, (B) reclamation costs, (C) land holding costs and (D) any other costs not directly related to exploration and development of the Lewiston Property (“Work”) with such expenditures estimated to be broken out as follows: (i) one hundred thousand dollars ($100,000) before the first anniversary of the Effective Date; (ii) an additional two hundred thousand dollars ($200,000) before the second anniversary of the Effective Date; (iii) an additional five hundred thousand dollars ($500,000) before the third anniversary of the Effective Date; and (iv) the final two hundred thousand dollars ($200,000) before the fourth anniversary of the Effective Date. In the event that the GPMUS disputes any exploration expenditures, GPMUS may notify Big Bear in writing and Big Bear shall provide GPMUS with reasonable access to its books and records relating to the disputed exploration expenditures for the purpose of conducting an audit of same, which shall be performed at the expense of GPMUS by a recognized CPA. In the event that the amount of exploration expenditures reported by the auditor are less than those reported by Big Bear, the exploration expenditures shall be deemed to be that lower figure and, if (but only if) the discrepancy is greater than 10%, Big Bear shall be responsible for paying the costs of such report. In the event that Big Bear spends, in any period, more than the specified sum, the excess shall be carried forward and applied to the exploration expenditures to be incurred in the succeeding period; and

Make all payments to the lessors required by the Underlying Agreements, pay all taxes, fees and other charges required to maintain the Lewiston Property in good standing from the Effective Date to the earlier of (i) the relinquishment and forfeiture of the Purchase Option as describe in Paragraph 10, or (ii) the exercise of the Purchase Option in compliance with this Paragraph 6.

If, at any point, Big Bear fails to fund the amount of exploration expenditure for that period required under Section 6(c), Big Bear will nevertheless be deemed to have satisfied Section 6(c), if Big Bear, on or before the expiry of that period, pays GPMUS an amount which is equal to the difference between the sum of the actual exploration expenditure funded by Big Bear in that period and the exploration expenditure set out in Section 6(c) that ought to have been funded by Big Bear in that period.

Performance of the Work. Big Bear initially plans to undertake a drilling program, and may also undertake a geophysical program, to evaluate target areas within the Lewiston Property. However, throughout the term of this Agreement, the scope and details of the Work and scheduling will be at Big Bear’s sole discretion.

Consents; No Shop. GPMUS covenants and represents that except for the consents required under the Underlying Agreements and any necessary approvals or consents of governmental entities having jurisdiction over the Lewiston Property, as of the Effective Date there are no, and throughout the term of this Option Agreement there are shall not be, any third party rights of refusal, consent or encumbrances burdening the Lewiston Property (save those previously disclosed to Big Bear), other than encumbrances of record as of the Effective Date including easements and rights of way, all rights of taxation and in all cases the paramount jurisdiction of the United States. Upon its execution of this Option Agreement and receipt of the Option Payment, and for so long as Big Bear is not in default of its obligations under this Agreement GPMUS agrees (i) to suspend any and all negotiations in which GPMUS may be currently involved with other persons or entities with regard to the sale of all or any part of the Lewiston Property; and (ii) neither solicit, nor entertain bids or other expressions of interest from third parties concerning the Lewiston Property

9.	Sale and Conveyance. Upon Big Bear’s completion of the earn-in deliverables set out in Paragraph 6 above prior to the fourth (4th) anniversary of the Effective Date:

b.	Within or concurrent with such conveyances, GPMUS will reserve unto itself an additional sliding scale royalty for net smelter returns (“NSR”) production royalty in mineral products produced from the Lewiston Property as more specifically described on Attachment B to this Option Agreement.

The parties hereby stipulate that Big Bear’s completion of the deliverables set out in Paragraph 6 together with accepting the Lewiston Property burdened with the NSR royalties described in Attachments A and B shall be full and sufficient purchase consideration for the Lewiston Property, including any interests acquired by GPMUS after the Effective Date.

d.	The confidentiality obligations set forth in this Option Agreement shall supersede and replace in its entirety the Confidentiality Agreement.

10.

Relinquishment and Forfeiture. At any time prior to the fourth (4th) anniversary of the Effective Date, upon written notice to GPMUS, Big Bear may relinquish, at its sole discretion, its Purchase Option, without further obligation or liability owed to GPMUS except for those obligations set forth herein. By relinquishment, Big Bear shall forfeit to GPMUS all cash payments and shares delivered, and Work expended, prior to notification of relinquishment; however, Big Bear shall have no further duty to complete the deliverables set out in Paragraph 6 and shall not owe GPMUS any further cash payments, shares, or Work.

For example if the royalty burden on a claim is three and three quarters percent (3.75%) on the Effective Date, GPMUS may further burden that claim by retaining an additional sliding scale royalty interest that will fluctuate, in accordance with the values described above, with the price of gold from a maximum of two percent (2%) interest in net smelter returns when the price of gold is equal to or greater than two thousand dollars ($2000) per ounce to a minimum of three percent interest in net smelter returns when the price of gold is less than five hundred dollars ($500) per ounce. The price of gold shall be determined by the gross spot price of gold on the London Bullion market or other mutually agreeable price source or index on the day the smelter or other recipient of such production credits the account of Big Bear.

The Royalty will run with the land and not be merely contractual in nature. To this end Big Bear will cooperate with GPMUS in recording the Royalty on title to the claims.

1) Definitions. The terms defined in the instrument to which this Exhibit is attached and made part of shall have the same meanings in this Exhibit. The following definitions shall apply to this Exhibit.

a) "Gold Production" means the quantity of refined gold outturned to Payor's account by an independent third party refinery for gold produced from the Property during the quarter on either a provisional or final settlement basis.

b) "Gross Value" shall be determined on a quarterly basis and have the following meanings with respect to the following Minerals:

i) Gold

(a) If Payor sells gold concentrates, dore or ore, then Gross Value shall be the value of the gold contained in the gold concentrates, dore and ore determined by utilizing: (1) the mine weights and assays for such gold concentrates, dore and ore; (2) a reasonable recovery rate for the refined gold recoverable from such gold concentrates, dore and ore (which shall be adjusted annually to reflect the actual recovery rate of refined metal from such gold concentrates, dore and ore); and (3) the Quarterly Average Gold Price for the quarter in which the gold concentrates, dore and ore were sold.

(b) If Payor produces refined gold (meeting the specifications of the London Bullion Market Association, and if the London Bullion Market Association no longer prescribes specifications, the specifications of such other association generally accepted and recognized in the mining industry) from Minerals, and if Section 1.2.1(a) above is not applicable, then for purposes of determining Gross Value, the refined gold shall be deemed to have been sold at the Quarterly Average Gold Price for the quarter in which it was refined. The Gross Value shall be determined by multiplying Gold Production during the quarter by the Quarterly Average Gold Price.

ii) Silver.

(a) If Payor sells silver concentrates, dore or ore, then Gross Value shall be the value of the silver contained in the silver concentrates, dore and ore determined by utilizing: (1) the mine weights and assays for such silver concentrates, dore and ore; (2) a reasonable recovery rate for the refined silver recoverable from such silver concentrates, dore and ore (which shall be adjusted annually to reflect the actual recovery rate of refined metal from such silver concentrates, dore and ore); and (3) the Quarterly Average Silver Price for the quarter in which the silver concentrates, dore and ore were sold.

(b) If Payor produces refined silver (meeting the specifications for refined silver subject to the New York Silver Price published by Handy & Harmon, and if Handy & Harmon no longer publishes such specifications, the specifications of such other association or entity generally accepted and recognized in the mining industry) from Minerals, and if Section 1.2.2(a) above is not applicable, the refined silver shall be deemed to have been sold at the Quarterly Average Silver Price for the quarter in which it was refined. The Gross Value shall be determined by multiplying Silver Production during the quarter by the Quarterly Average Silver Price.

iii) All Other Minerals.

(a) If Payor sells any concentrates, dore or ore of Minerals other than gold or silver, then Gross Value shall be the value of such Minerals determined by utilizing: (1) the mine weights and assays for such Minerals; (2) a reasonable recovery rate for the Minerals (which shall be adjusted annually to reflect the actual recovery rate of recovered or refined metal or product from such Minerals); and (3) the quarterly average price for the Minerals or product of the Minerals for the quarter in which the concentrates, dore or ore was sold. The quarterly average price shall be determined by reference to the market for such Minerals or product which is recognized in the mining industry as authoritative and reflective of the market for such Minerals or product.

(b) If Payor produces refined or processed metals from Minerals other than refined gold or refined silver, and if Section 1.2.3(a) above is not applicable, then Gross Value shall be equal to the amount of the proceeds received by Payor during the quarter from the sale of such refined or processed metals. Payor shall have the right to sell such refined or processed metals to an affiliated party, provided that such sales shall be considered, solely for purposes of determining Gross Value, to have been sold at prices and on terms no less favorable than those that would be obtained from an unaffiliated third party in similar quantities and under similar circumstances.

c) "Minerals" means gold, silver, platinum, antimony, mercury, copper, lead, zinc, and all other mineral elements and mineral compounds, but not geothermal resources, which are contemplated to exist on the Property or which are after the Effective Date discovered on the Property and which can be extracted, mined or processed by any method presently known or developed or invented after the Effective Date.

d) "Quarterly Average Gold Price" means the average London Bullion Market Association Afternoon Gold Fix, calculated by dividing the sum of all such prices reported for the quarter by the number of days for which such prices were reported during that quarter. If the London Bullion Market Association Afternoon Gold Fix ceases to be published, all such references shall be replaced with references to prices of gold for immediate sale in another established marked selected by Payor, as such prices are published in Metals Week magazine, and if Metals Week magazine no longer publishes such prices, the prices of such other association or entity generally accepted and recognized in the mining industry.

e) "Quarterly Average Silver Price" means the average New York Silver Price as published daily by Handy & Harmon, calculated by dividing the sum of all such prices reported for the quarter by the number of days in such quarter for which such prices were reported. If the Handy & Harmon quotations cease to be published, all such references shall be replaced with references to prices of silver for immediate sale in another established market selected by Payor as published in Metals Week magazine, and if Metals Week magazine no longer publishes such prices, the prices of such other association or entity generally accepted and recognized in the mining industry.

f) "Net Smelter Returns" means the Gross Value of all Minerals, less the following costs, charges and expenses paid or incurred by Payor with respect to the refining and smelting of such Minerals:

i) Charges for smelting and refining (including sampling, assaying and penalty charges), but not any charges or costs of agglomeration, beneficiation, crushing, extraction, milling, mining or other processing; and

ii) Actual costs of transportation (including freight, insurance, security, transaction taxes, handling, port, demurrage, delay and forwarding expenses incurred by reason of or in the course of such transportation) of concentrates or dore metal from the Property to the smelter or refinery, but not any charges or costs of transportation of Minerals or ores from any mine on the Property to an autoclave, concentrator, crusher, heap or other leach process, mill or plant.

g) "Property" means the real property described in the instrument to which these Net Smelter Returns provisions are attached and made a part.

h) "Silver Production" means the quantity of refined silver outturned to Payor's account by an independent third-party refinery for silver produced from the Property during the quarter on either a provisional or final settlement basis.

2) Payment Procedures.

a) Accrual of Obligation. Payor's obligation to pay the royalty shall accrue and become due and payable upon the sale or shipment from the Property of unrefined metals, dore metal, concentrates, ores or other Minerals or Minerals products or, if refined metals are produced, upon the outturn of refined metals meeting the requirements of the specified published price to Payor's account.

b) Futures or Forward Sales, Etc.. Except as provided in Sections 1.2.1(a), 1.2.2(a) and 1.2.3 (a) (regarding sales of unprocessed gold and silver and sales of Minerals other than gold and silver), Gross Value shall be determined irrespective of any actual arrangements for the sale or other disposition of Minerals by Payor, specifically including but not limited to forward sales, futures trading or commodities options trading, and any other price hedging, price protection, and speculative arrangements that may involve the possible delivery of gold, silver or other metals produced from Minerals.

c) Quarterly Calculations and Payments. Net Smelter Returns royalties shall be determined on a quarterly basis. Payor shall pay Payor each quarterly royalty payment on or before the last business day of the quarter immediately following the quarter in which the royalty payment obligation accrued. Payor acknowledges that late payment by Payor to Recipient of royalty payments will cause Recipient to incur costs, the exact amount of which will be difficult to ascertain. Accordingly, if any amount due and payable by Payor is not received by Recipient within ten (10) days after such amount is due, then Payor shall pay to Recipient a late charge equal to 10 percent (10%) of such overdue amount. Recipient’s acceptance of such late charge shall not constitute a waiver of Payor’s default with respect to such overdue amount, nor prevent Recipient from exercising any of Recipient’s other rights and remedies. If any amount payable by Payor remains delinquent for a period in excess of thirty (30) days, Payor shall pay to Recipient, in addition to the late payment, interest from and after the due date at the statutory interest rate.

d) Statements. At the time of payment of the royalty, Payor shall accompany such payment with a statement which shows in detail the quantities and grades of refined gold, silver or other metals or dore, concentrates or ores produced and sold or deemed sold by Payor in the preceding quarter; the Quarterly Average Gold Price and Quarterly Average Silver Price, as applicable; costs and other deductions, and other pertinent information in detail to explain the calculation of the payment with respect to such quarter. Payment shall be made to the address provided in the agreement or instrument to which this Exhibit is attached for purposes of notices or by wire transfer to an account which Recipient designates.

e) Inventories and Stockpiles. Payor shall include in all quarterly statements a description of the quantity and quality of any gold or silver dore that has been retained as inventory for more than ninety (90) days. Recipient shall have thirty (30) days after receipt of the statement to either: (a) elect that the dore be deemed sold, with Gross Value to be determined as provided in Sections 1.2.1 (b), with respect to gold, and 1.2.2(b), with respect to silver, as of such thirtieth (30th) day utilizing the mine weights and assays for such dore and utilizing a reasonable recovery rate for refined metal and reasonable deemed charges for all deductions which Payor is authorized to take, or (b) elect to wait until such time as the royalty payment otherwise would become payable pursuant to Sections 1.2.1(b) and 1.2.2(b). The Payor’s failure to respond within such time shall be deemed to be an election to use the methods described in Sections 1.2.1(b) and 1.2.2(b).

f) Audit. Upon reasonable notice and at a reasonable time, the Recipient shall have the right to audit and examine the Payor’s accounts and records relating to the calculation of the Net Smelter Returns royalty payments. If such audit determines that there has been a deficiency or an excess in the payment made to Recipient, such deficiency or excess shall be resolved by adjusting the next quarterly royalty payment due Recipient. Recipient shall pay all costs of such audit unless a deficiency of three percent (3%) or more of the royalty payment due for the calendar quarter in question is determined to exist. All books and records used by Payor to calculate the royalty payments shall be kept in accordance with generally accepted accounting principles applicable to the mining industry.

3) Sampling and Commingling. Payor shall have the right to commingle Minerals and ores from the Property and materials from other properties, provided, that Payor first informs Recipient, in writing, of Payor’s intention to commingle and delivers to Recipient a detailed written description of Payor’s commingling plan. Recipient shall have ninety (90) days during which to review and comment on Payor’s proposed commingling plan. In any and all events, all Minerals and ores shall be measured and sampled by Payor in accordance with sound mining and metallurgical practices for metal and mineral content before commingling of any such Minerals or ores with materials from any other property. Representative samples of materials from the Property intended to be commingled shall be retained by Payor, and assays of these samples shall be made before commingling to determine the metal content of each ore. Detailed records shall be kept by Recipient showing measurements, assays of metal content and gross metal content of the materials from the Property are commingled.
