RE: Tarsis Resources Ltd. (“Tarsis” or the “Company”) – Notification of Transaction

Dear Sir / Madam:

Pursuant to National Instrument NI 51-102 Continuous Disclosure Requirement, Section 4.8 Change of Year-End:

1.

The reporting issuer, Tarsis, has decided to change its year-end.

2.

Tarsis’ old financial year-end is October 31.

3.

Tarsis’ new financial year-end is September 30.

4.

The reason for the change is for Tarsis’ year end to be coterminous with its wholly owned subsidiary in Mexico, Minera Tarsis, S.A. de C.V. which has a December 31 year-end. In addition, the change in Tarsis’ year-end will expedite Tarsis reporting the equity interest that Almaden Minerals Inc. (“Almaden”) has in the Company as Almaden also has a December 31 year­end.

5.

With respect to the comparative periods and the statements required during the transition and the first year after the transition, the Company will file:
