According to Anacortes, Tres Cruces ranks among the highest-grade gold oxide development projects globally, with 9.6 million indicated tonnes grading 1.37 grams gold per tonne for 425,000 contained oz. of gold in oxide material. The project also hosts an additional indicated resource of 31 million tonnes at 1.84 grams gold for 1.8 million oz. of gold in leachable sulphides.
Mineral resources for Tres Cruces currently stand at 46.5 million indicated tonnes grading 1.65 grams gold per tonne for 2.5 million oz. contained gold and 2.6 million inferred tonnes of 1.26 grams gold for 104,000 oz. gold.
In March, the company released an initial preliminary economic assessment for the project.
The early-stage study envisions an open pit heap-leach mining operation producing 68,000 oz. of gold annually over an initial oxide mine life of seven years, with peak production of 81,000 oz. in the…
