Pursuant to the Offering:

• a total of 9,990,200 units of the Company (the "Units") were offered at a price of $0.37 per Unit (the "Issue Price") by Clarus Securities Inc. ("Clarus"), as lead agent, on behalf of a syndicate of agents including PI Financial Corp. and Roth Canada, Inc. (collectively, the "Agents") for gross proceeds of $3,696,374 pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 – Prospectus Exemptions (the "Brokered Portion"); and

• a total of 8,928,824 Units were offered directly by the Company at the Issue Price pursuant to a concurrent non-brokered private placement for additional gross proceeds of $3,303,664.88 (the "Non-Brokered Portion").

Each Unit is comprised of one common share in the capital of the Company ("Common Share") and one-half of one Common Share purchase warrant (each whole warrant, a "Warrant"). Each Warrant will entitle the holder to purchase one Common Share for a period of 18 months, at an exercise price of $0.50 for an initial period of six months, after which time the exercise price will increase to $0.70 for the remaining term of the Warrant.

The Company intends to use the net proceeds of the Offering to continue the exploration and development work on its Ana Paula Project in Guerrero, Mexico, as well as general corporate working capital purposes.

The Units issued pursuant to the Brokered Portion are not subject to resale restrictions pursuant to applicable Canadian securities laws. The Units issued pursuant to the Non-Brokered Portion will be subject to the statutory hold period of four months and one day from the date of issuance in accordance with applicable Canadian securities laws. Closing of the Offering is subject to final approval of the TSX Venture Exchange (the "TSXV").

As consideration for their services in connection with the Brokered Portion, the Company paid the Agents a cash commission of $221,782.44 and a corporate finance fee of $30,000 including HST. In addition, the Company issued to the Agents 599,412 non-transferable compensation options (the "Compensation Options"). Each Compensation Option entitles the holder to purchase one Common Share at the Issue Price for a period of 18 months.

The Company also paid a finder's fee to 3L Capital Management, LLC (the "Finder") in connection with a portion of the Non-Brokered Portion, consisting of a cash fee of $41,400.78. In addition, the Company issued the Finder 111,894 non-transferable finder's warrants (the "Finder's Warrants"). Each Finder's Warrant entitles the holder to purchase one Common Share at the Issue Price for a period of 18 months.

Certain insiders of the Company subscribed for an aggregate of 27,100 Units for gross proceeds of $10,027 under the Non-Brokered Portion.

The issuance of securities is exempt from the formal valuation requirements of Section 5.4 of MI 61-101 pursuant to Subsection 5.5(b) of MI 61-101 as the Common Shares are listed on the TSXV. The issuance of securities is also exempt from the minority approval requirements of Section 5.6 of MI 61-101 pursuant to Subsection 5.7(1)(b) of MI 61-101 as the fair market value was less than $2,500,000.
