As announced in a press release dated January 13, 2025, the Company recommenced construction

activities at the Fenix Gold Mine in October 2024 after successfully completing a debt and equity

financing for the construction of the mine announced on October 29, 2024.

The projected construction capex for 2025 is estimated to be USD 12 2 M (excluding Chilean VAT tax

which is refundable) with construction expected to be completed in November 2025. First gold

production is currently guided for January 2026.

FENIX GOLD PROJECT

The Fenix Gold Project is one of the largest undeveloped gold oxide, heap leach projects in the

Americas, hosting a Measured and Indicated mineral resource (as such term is defined in National

Instrument 43-101 -Standards of Disclosure for Mineral Projects, “NI 43-101”) of 4.8 million ounces of

gold which the Company believes will make a positive contribution to the Atacama Region and Chile.

The Project is an example of modern gold mining where a full complement of technical,

environmental, and social considerations has been consulted and designed from the outset. The

Project represents a significant investment in the gold mining business in Chile by a junior mining

company of approximately US$235M of initial and sustaining capital, generating employment for at

least 1,200 people during the construction phase and 550 people during the 17-year operations phase.

The mine being contemplated will be a run-of-mine heap leach operation; no crushing or tailings

storage facilities are required, thereby minimizing the overall impact and footprint of the Project.
