The Company will grant to Red Cloud an option, exercisable up to 48 hours prior to the Closing Date, to purchase for resale up to an additional 3,846,154 Units at the Offering Price for additional gross proceeds of up to approximately C$1,000,000 (the "Over-Allotment Option"). The Underwritten Offering and the securities issuable upon exercise of the Over-Allotment Option shall be collectively referred to as the "Offering".

The Company intends to use the net proceeds from the Offering for the advancement of the Company's Rio Grande Project in the Salta Province of Argentina, as well as for general corporate purposes and working capital.

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 - Prospectus Exemptions ("NI 45-106"), the Units will be offered: (a) by way of a private placement to purchasers resident in the provinces of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario (and, with the consent of the Company, in Québec) pursuant to the listed issuer financing exemption under Part 5A of NI 45-106, as amended by Coordinated Blanket Order 45-935 - Exemptions from Certain Conditions of the Listed Issuer Financing Exemption; (b) in the United States or to, or for the account or benefit of, U.S. persons, by way of private placement pursuant to the exemptions from the registration requirements provided for under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"); and (c) in jurisdictions outside of Canada and the United States on a private placement or equivalent basis, in each case in accordance with all applicable laws, provided that no prospectus, registration statement or other similar document is required to be filed in such jurisdiction.
