Information on the target

Tesoro Gold Limited (ISIN: AU0000077208) is a prominent player in the gold mining sector, particularly noted for its significant developments in the Ternera deposit located in Chile. As of September 18, 2026, the company announced its first ore reserve, marking a pivotal milestone in its operational trajectory. The newly established ore reserve comprises 42.8 million tonnes with an average grade of 0.93 grams of gold per tonne, translating to approximately 1.28 million ounces of gold. This reserve is entirely situated within a planned open-pit mining operation, showcasing the company's commitment to advancing its mining projects.

Previously, Tesoro Gold had identified 1.47 million ounces of "Measured" and "Indicated" resources, successfully converting around 87% of these into reserves. This transition is crucial in the mining industry, as it signifies a shift from merely geological estimates to economically viable and technically feasible mining plans. The Ternera reserve supports a projected mine life exceeding 13 years, with an annual processing capacity of three million tonnes, further solidifying Tesoro's position in the competitive gold market.
