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 800 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.
The scientific and technical content of this news release has been reviewed, approved and verified by Enrique
Garay, MSc P.Geo/FAIG, who is a qualified person under NI 43-101. For additional information regarding the
Project, including key parameters, assumptions and risks associated with its development, see the independent
technical report entitled “NI 43-101 Technical Report on the Feasibility Study for the Fenix Gold Project” (the

43-101”). The Feasibility Study is dated October 16, 2023, with an effective date of October 16, 2023, a copy
