ATICO MINING ANNOUNCES CLOSING OF THE FULLY SUBSCRIBED $3.2M LIFE OFFERING, RAISING $6.5M COMBINED WITH THE RIGHTS OFFERING

Atico Mining Corp. has closed its offering under the listed issuer financing exemption (LIFE), previously disclosed in the company's news releases dated June 9, 2025, June 13, 2025, and July 22, 2025. Under the LIFE offering, Atico sold 29,090,910 units of the company, at a subscription price of 11 cents per LIFE unit, for gross proceeds of $3.2-million. Under the LIFE offering and the company's rights offering that closed on July 22, 2025, the company raised aggregate gross proceeds of $6,487,572.42.

"We are thrilled with the successful completion of our rights and LIFE offerings, which have significantly strengthened our financial foundation. This achievement positions us to advance our strategic goals at both El Roble mine and the La Plata project," said Fernando E. Ganoza, chief executive officer. "I extend my gratitude to our loyal shareholders, new investors and company insiders for their substantial support and trust in our vision. Together, we are poised to steer back the company toward becoming a top mid-tier producer."

Each LIFE unit consisted of one common share of the company and one transferable common share purchase warrant, with each LIFE warrant exercisable into one common share at a price of 18 cents per LIFE warrant share for a period of two years from the issue date.

In connection with the LIFE offering, PowerOne Capital Markets Ltd. acted as finder in connection with a portion of the LIFE offering. The company paid a cash finder's fee of approximately $62,820 and issued 571,091 non-transferable common share purchase warrants to the finder, an arm's-length party to the company. Each finder's warrant is exercisable for one common share at an exercise price of 18 cents for a period of two years following the closing date of the LIFE offering.

The LIFE units were issued pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106, Prospectus Exemptions. Certain LIFE units were also issued in the United States pursuant to exemptions from the registration requirements in Regulation D of the U.S. Securities Act of 1933, as amended.

The company intends to use the net proceeds from the offerings to pay for development of the company's La Plata project in Ecuador, for additional drilling at the company's El Roble mine in Colombia and for general corporate purposes.

Following closing of the LIFE offering, the company has a total of 180,264,117 common shares outstanding.

Certain officers of the company, considered related parties under Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transaction, acquired an aggregate of 590,001 LIFE units under the LIFE offering. Accordingly, the LIFE offering constituted a related party transaction under MI 61-101. The LIFE offering is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 pursuant to sections 5.5(b) and 5.7(1)(a) of MI 61-101, as the company is not listed or quoted on any of the stock exchanges or markets listed in subsection 5.5(b) of MI 61-101, and the fair market value of the securities distributed and the consideration received for the securities under the LIFE offering does not exceed 25 per cent of the company's market capitalization.
