Interra Copper Corp. provided an update on its exploration activities at its Tres Marias Copper Project (the "Project"), located approximately 40 km southwest of the city of Calama in the Antofagasta Region of Chile. Phase 1 of the drilling program at Tres Marias which began on May 24, 2023 is complete.

In total, six RC holes totaling 1,896 m were drilled. Samples were sent to ALS Global in Santiago for analysis and results are expected in early August. Sociedad Perforaciones E Inginieria Chile Limitada ("PerfoChile"), a local business and experienced drilling contractor that services many of the large producing mines in Chile, completed the first phase of the Reverse-Circulation ("RC") drilling campaign.

PerfoChile has now demobilized and the project site has been rehabilitated.
