Magnetics surveys commence at Great Southern Copper’s Especularita project

Great Southern Copper, a company focused on copper-gold exploration in Chile, has announced that it has commenced high-resolution aeromagnetic surveys at its Especularita project.

The Company plans to complete two magnetic surveys covering each of its Teresita and Victoria prospects where recent exploration has identified outcropping high-grade Cu-Au mineralisation with reported rock chip sampling results up to 6.7% Cu and 13.1 g/t Au. The surveys are designed to identify and delineate potentially high-grade, vein and breccia type Cu-Au deposits as described in previous announcements, and will also enhance the Company’s understanding of the district geology.

Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “We are very pleased to commence our first magnetic surveys at the Teresita and Victoria prospects. Recent exploration work at the prospects suggests that the alteration associated with the high-grade Cu-Au mineralisation is both non-magnetic and magnetite-destructive whereas the surrounding wall rocks are magnetic. Therefore, we expect that zones of potential mineralisation will be visible in the magnetic data. This will be used to support our drill targeting for the scout drilling programmes planned for later in the year.”

Magnetic Survey GSC has contracted GFDas UAV & Geosciences of Santiago, Chile to collect the magnetic survey data using two drone-mounted magnetometers. The surveys will be flown at an above-ground height of 35 m on 50 m-spaced grid lines covering an area of 29.1 km2 at Victoria (651 line-km) and 22 km2 at Teresita (514 line-km).

The Company anticipates that the survey will be completed within 3 – 4 weeks. Additional processing and interpretation of the data by ExploreGeo of Perth, Australia, is estimated to be completed within a further 4 – 6 weeks subject to availability of consultants.

ESG considerations: The Company is employing the latest in battery-powered drone technology to collect the magnetic data which has the collective benefits of reducing the Company’s on-ground footprint, reducing CO2 emissions and noise pollution compared with using conventional helicopter and plane-mounted systems as well as significantly reducing the time and cost to complete the survey.
