Fueling the future with copper

SRHI’s Minera Tres Valles (MTV) copper mine is peppered with potential. Already producing 99.999% pure copper cathodes from its reserves, MTV has over 46,000 hectares of land to explore with over 100 copper occurrences mapped and 70 artisanal exploitation points registered having geological characteristics similar to that of its identified orebodies.


In an attractive mining jurisdiction, MTV’s neighborhood boasts a number of successful Chilean operating copper mines. An opportunity to grow, is just around the corner
