Encouraged by recent work on the Bajo de la Alumbrera copper-gold deposit, International Musto Explorations (VSE) anticipates improved project economics for the advanced porphyry deposit in northwestern Argentina.
According to preliminary studies, the project is reported to host 340 million tonnes of minable reserves grading 0.53% copper and 0.07 grams (0.02 oz.) gold per tonne.
A feasibility study is continuing, and Musto reports that results are confirming the accuracy of the assay database as developed by others in the 1980s.
Some 491 core samples representing about 10% of the entire database were reassayed, with results indicating “a trend for a strong upside potential in both copper and gold above nominal cutoffs.” The company intends, however, to be conservative and use the original assay database for current reserve estimate and mine planning work.
