15.0 SURRENDER AND ACQUISITION OF PROPERTY

INTERESTS BEFORE TERMINATION OF AGREEMENT

15.1 Evanachan may at any time during the Option Period, elect to have any one or more of the mineral claims comprised in the Property excluded from the Property (an “Abandoned Area”) by giving notice to Rimfire of such intention.

-21-

15.2 For greater certainty, the aggregate Expenditures of US$4,800,000 as set out in Section 4.2 shall not be reduced as a result of any one or more Abandoned Areas being excluded from the Property pursuant to Section 15.1.

15.3 In the event Evanachan does not incur the minimum amount of Expenditures set out in Section 4.5 for any one or more of the four claim blocks that comprise the Property, those claims upon which minimum Expenditures have not been incurred shall be deemed to be Abandoned Areas upon the expiration of the First Option Period.

15.4 The mineral claims comprising any one or more Abandoned Areas pursuant to Sections 15.1 or 15.3 will, for all purposes of this Agreement, cease to form part of the Property.

15.5 Any claims comprising one or more Abandoned Areas shall be in good standing under the applicable laws of Alaska for at least 90 days from the earlier of the date of:

(a)

delivery to Rimfire of the notice contemplated in Section 15.1; or

(b)

actual delivery to Rimfire of notice confirming a deemed abandonment pursuant to Section 15.3.

15.6 Where any or all mineral claims comprising an Abandoned Area are held by Evanachan, Rimfire may at any time during the 90 day notice period set out in Section 15.5, deliver notice to Evanachan requesting the transfer of said mineral claims to Rimfire. Upon receipt of such notice, Evanachan will deliver to Rimfire a xxxx of sale or other appropriate deed or assurance in registerable form transferring such mineral claims to Rimfire.

15.7 If Rimfire fails to make request for the transfer of any mineral claims as set out in Section 15.5 within such 90 day period, Evanachan may then abandon such mineral claim without further notice to Rimfire.

16.0 FORCE MAJEURE

16.1 No party shall be liable to any other party hereto and no party shall be deemed in default hereunder for any failure to perform or delay in performing any of its covenants and agreements or in incurring Expenditures caused by or arising out of any event (a “force majeure event”) beyond the reasonable control of such party, excluding lack of funds but including, without limitation, lack of rights or permission by indigenous peoples’ groups to enter upon the

-22-

Property to conduct exploration, development and mining operations thereon, or war conditions, actual or potential, earthquake, fire, storm, flood, explosion, strike, labour trouble, accident, riot, unavoidable casualty, act of restraint, present or future, of any lawful authority, act of God, protest or demonstrations by environmental lobbyists or indigenous peoples’ groups, act of the public enemy, delays in transportation, breakdown of machinery, inability to obtain necessary materials in the open market or unavailability of equipment. No right of a party shall be affected for failure or delay of a party to perform any of its covenants and agreements hereunder or to incur Expenditures if the failure or delay is caused by one of the events referred to above. All times provided for in this Agreement shall be extended for the period commensurate with the period of delay and, so far as possible, the party affected shall take all reasonable steps to remedy the cause of the delay attributable to the events referred to above; provided, however, that nothing contained in this section shall require any party to settle any labour dispute, protest or demonstration, or to question or test the validity of any governmental order, regulation, or law or claim of right by indigenous peoples’ groups. Notwithstanding the foregoing, a force majeure event will not discharge Evanachan from its obligations under Section 11.1(a).

16.2 The party affected by a force majeure event will within five days give notice to the other party of each force majeure event under Section 16.1 and upon cessation of such event will furnish to the other party with notice to that effect together with particulars of the number of days by which the obligations of the affected party hereunder have been extended by virtue of such event of force majeure and all preceding events of force majeure.
