Atacama Copper Provides Trenching Program Update at the El Cofre Copper-Gold Project

May 24, 2022

Vancouver, British Columbia – May 24, 2022 – Atacama Copper Corporation (TSXV: ACOP) ("Atacama Copper" or the "Company") provides an update on its trenching program at its 100% owned El Cofre Copper-Gold Project.  

Highlights:

  • 40% of 3,000m trenching program completed
  • Multiple zones of copper oxide mineralization identified
  • Over 156 samples collected and analyzed by XRF to date
  • Copper-gold mineralization identified across 1 to 5 meter wide mineralized veins over a strike length of 600m, with 800m remaining to be tested
  • Laboratory results expected in early June 2022

Gino Zandonai, CEO of Atacama Copper, said,"We are pleased to announce we are progressing on schedule with the trenching program on the El Cofre copper project, and we have confirmed the presence of copper mineralization along 600 meters strike into a 1.4km length of copper oxides occurrences corridor. This program is the first phase of a more extensive work program on the project. It is designed to gather additional targeting information and increase the knowledge of the type and geometry of the mineralization, which allows for identifying a number of high-priority target zones across the property."

Trenching program is currently 40% completed, including trenching, sampling, and mapping focused on the Viñita area. The overall trenching program is planned to excavate around 3,000 meters over 18 designed trenches and channel sampling lines focused on the northern section of the project area, the Viñita and Gloria areas.  The program is targeting existing mapped mineralized structures and geochemical/geophysical anomalies. The completion of 18 trenches is subject to environmental evaluation and clearance, of which 70% of the planned trenches have already been approved for excavation.

The trench program to date has identified a fault-vein mineralized structure at Viñita, dipping 70° to the west and shows pockets of high-grade mineralization.  In the Viñita South area the mineralised structure has been mapped along a strike length of at least 600 m in length.  This sequence is part of a longer 1.4km long structural corridor of discontinuous mineralisation.  The mapped mineralized fault-vein’s vary between 1 to 5 meters in width with local combined structures up to 15 meters in width.  The mapped veins are observed between 365 and 212 meters of elevation, which infers at least 150 meters of vertical continuity to the mineralization.

The geological mapping has been supported by XRF measurement. Channel and rock chip sampling are taken at one-meter intervals along the open trench. To date, referential XRF measurement (Olympus Delta) has been taken systematically over 156 samples in the company warehouse and by a certified operator to confirm and support the mineralization mapping of black oxides, copper-rich limonite, and copper oxides in general. The results from certified laboratory analysis of the samples are expected in early June 2022.
