Great Southern Copper PLC (LON: GSCU) CEO Sam Garrett spoke with Andrew Scott about the company’s initial assay results from phase one drilling at the Mostaza mine. Garrett emphasised the outstanding findings, including a remarkable sixfold increase in copper grade compared to historical data.
The drilling focused on hole EDH25, which had previously recorded 25 meters at 0.53% copper. Garrett stated, “These results, obtained just a few meters away, effectively reflect a 600% increase in copper grade.” This indicates that historical grades may have been underestimated, presenting new opportunities for the company.
Great Southern Copper is preparing for the next phase of drilling, with results from eight additional holes anticipated in the coming weeks. The company plans to expand its resource drilling within the mine and investigate mineralization trends to the south, where encouraging indicators have been observed.
Sam Garrett, Chief Executive Officer of Great Southern Copper, said: “This is a tremendously significant result for both copper and silver. These exceptional and exciting assay grades demonstrate that the former Mostaza mine has the potential to be a high-grade high-value Cu-Ag deposit.
Drill hole CNG25 DD001 was designed specifically to verify the width and grade of mineralisation reported in historical drill hole EDH25, which reported 25.33m of 0.53% Cu. Drill samples for EDH25 were assayed at uncertified local facilities in the early 1980’s so it was important to confirm the veracity of these results from the outset. Assay grades for CNG25 DD001 are significantly higher than the historically reported EDH25 results and if this is confirmed in other GSC drillholes, it could have a positive impact on the potential economics of the Mostaza resource.
We are hopeful that the remaining GSC holes at Mostaza will return further exciting results and look forward to updating the market. Planning for the next phase of drilling plus metallurgical test work is already underway.”

About Great Southern Copper
Great Southern Copper PLC is a UK-listed mineral exploration company focused on the discovery of copper-gold and lithium deposits in Chile. The Company has the option to acquire rights to 100% of two projects in the under-explored coastal belt of Chile that are prospective for large scale copper-gold deposits. In addition, the Company has the option to acquire rights to 100% of a lithium project located in the Salar de Atacama district of Chile. Chile is a globally significant mining jurisdiction being the world’s largest copper producer and the second-largest producer of lithium.
The two, early-stage Cu-Au projects comprise the San Lorenzo and Especularita Projects, both located in the coastal metallogenic belt of Chile which hosts significant copper mines and deposits, including Teck’s Carmen de Andacollo copper mine, and boasts excellent access to infrastructure such as roads, power and ports. Significant historical small-scale and artisanal workings for both copper and gold are readily evident in both exploration project areas.
The Company’s Monti Lithium project is strategically located in the pre-Andean region of Salar de Atacama which is Chile’s premier lithium-producing region with well-established lithium mining operations and infrastructure.
Great Southern Copper is strategically positioned to support the global market for copper and lithium – both critical battery metals in the clean energy transition around the world. The Company is actively engaged in exploration and evaluation work programmes targeting both large tonnage, low to medium grade Cu-Au and Li deposits as well as high-grade Cu-Au deposits.
