Mirasol has rapidly established itself as an aggressive exploration company in Chile, building a large portfolio of 100% owned exploration claims in the Atacama Puna generative region of northern Chile and Argentina. The Atacama Puna region is a 1,700 km-long segment of prolifically mineralized Tertiary-aged volcanic arcs which host many world-class gold, silver and copper mines and deposits. Mirasol is actively focused on three mineral belts, targeting areas for discovery of high value mineral deposits.
The Atacama Puna program encompasses one of the world’s premier mining regions, hosting many operating large-scale to giant porphyry copper and gold mines, operated by the major mining companies. Despite a long mining history, the application of leading-edge exploration technologies and new mineral deposit models has, in recent years, delivered several new world-class gold and copper discoveries in the region.
Mirasol is applying its innovative target generation approach and our expert knowledge of High Sulfidation Epithermal (HSE) and Porphyry mineralization, to explore for these large high value deposits. During the recent challenging times in the resource industry, Mirasol has made a countercyclical commitment to expand its project generation efforts, giving the company a competitive advantage. Mirasol now has a full pipeline of exploration projects that are ready to be joint ventured to leading mining companies for drill testing.
The Atacama Puna program is focused on three highly productive mineral belts where Mirasol is applying its mineral deposit knowledge to target large-scale high-value gold, silver and copper deposit classes.
Mineral Belt Deposit Class
Miocene to Pliocene High-sulfidation epithermal (“HSE”) Au+Ag Middle Eocene to Early Oligocene Porphyry Cu+Mo Paleocene to Early Eocene Low- to intermediate-sulphidation epithermal Au+Ag and Porphyry Cu+Mo
The Miocene belt has been the focus of recent exploration due to the discoveries of the multi-million-ounce Alturas and Salares Norte HSE oxide gold deposits. These deposits are near-surface large-tonnage, oxide gold resources which are believed to be bulk-minable. Both are largely concealed beneath geochemically barren, but altered, cap rocks (the “steam heated cap”) which obscured recognition of these deposits. Mirasol is actively exploring for this type of gold deposit at its Atlas and Titan projects in the Gorbea Belt projects and at its other new pipeline projects in its Mio-Pliocene portfolio.
The Oligocene belt hosts many giant porphyry copper mines such as the super giant Escondida, Chuquicamata and Collahuasi mines. This copper belt is considered a “mature exploration terrain” but it is also recognized as prospective for further copper discoveries. This is due to its extensive post-mineral cover, and in some cases its “geochemically barren” alteration caps concealing a substantial proportion of the most productive and logistically accessible segments of the belt.

The Paleocene belt hosts significant mines including BHP’s porphyry Cu-Mo Spence mine and Yamana Gold’s high-grade low sulphidation epithermal (LSE) Au-Ag El Peñón mine. In this belt, Mirasol is targeting large multi-million-ounce epithermal gold and silver and large porphyry deposits.
