Great Southern Copper commences 2022 Especularita exploration campaign

Published by
Global Mining Review,


Great Southern Copper plc, a company focused on copper-gold exploration in Chile, has commenced systematic on-ground exploration at its Especularita copper-gold (Cu-Au) project located in the coastal metallogenic belt of northern Chile.

The Especularita project comprises 19 076 ha. of exploration and mining concessions, both granted and in the process of being granted, and the company holds option rights to acquire a 100% interest in the project.

The company’s exploration programmes at Especularita, targeting porphyry-epithermal style Cu-Au mineralisation, will comprise regional to prospect-scale mapping, sampling (rock, soil, stream) and geophysics work, designed to identify prospects for targeted drilling campaigns.

Previous reconnaissance exploration by GSC has identified porphyry to epithermal style Cu-Au mineralisation associated with an extensive advanced argillic litho-cap, centrally located at the intersection of major structures and the contact of a large granodiorite intrusion with overlying volcanic rocks. Such litho-cap alteration is characteristic of the tops of porphyry copper systems, including for example Teck’s 50 000 tpy Carmen de Andacollo copper mine, located along trend from Especularita.

Small-scale artisanal workings and mines, targeting high-grade Cu-Au mineralised structures, are prominent around the base of the litho-cap alteration zone. Historical processing plants and tailings dumps provide further evidence in the district of a once active mining culture, which has not benefited from significant modern-style exploration.

San Lorenzo

At the company’s San Lorenzo project, exploration continues on the Phase III trenching programme in conjunction with detailed mapping and sampling of monzonite intrusions. This work is progressing toward defining potential targets for drilling proposed to start in May/June 2022, subject to rig availability and permitting approvals.

Sam Garrett, CEO of Great Southern Copper, said: “We are pleased to begin our exploration campaign at the Especularita project, where previous geological mapping and sampling work has identified multiple large-scale targets and supports evidence of a complete porphyry-epithermal system prospective for copper-gold.”

Charles Bond, Chairman of Great Southern Copper, added: “The Board recently visited Especularita and San Lorenzo and is impressed by the quality of the projects and the opportunity they provide to the company. It is exciting to be actively exploring our two large scale exploration projects in Chile, the largest copper producing country in the world, and we look forward to updating our shareholders as we progress both projects toward drilling stage.”
