Interra Copper Begins Exploration Program at Its Tres Marias Copper Project in Chile

Vancouver, April 17, 2023 - Interra Copper Corp. (CSE: IMCX) (OTCQB: IMIMF) (FSE: 3MX) ("Interra" or the "Company") is pleased to announce its 2023 exploration plans at the Company's Tres Marias Copper Project (the "Project" or "Tres Marias") in the Antofagasta region of Chile. Tres Marias is one of three copper projects that the Company acquired in 2021 from Minera Freeport-McMoRan South America Ltda. The Project is located within the Paleocene Copper Porphyry Belt, about 30 km west of the mining centre of Calama and 30 km north of BHP Chile's Spence Mine.

The planned exploration program consists of 10,500 m of reverse circulation ("RC") drilling across three target areas within the 16,080 ha of contiguous concessions. The objective of the program is to test a number of targets identified in the technical work completed to date, which includes the reprocessed historical airborne ZTEM and 3D inversion of this airborne data, a 504 km UAV high-resolution magnetic survey, and a 29 line-km GDAS 3D induced polarization survey completed by Alto Verde Copper.

Chris Buncic, President & CEO of Interra stated, "We are excited to kick off our drilling campaign at Tres Marias and test the large coherent chargeability and resistivity anomalies that have been identified. Located on the same prolific copper belt that hosts a number of producing mines, including Spence and Sierra Gorda, the early work at Tres Marias shows that it is prospective for copper porphyry mineralization and we are eager to begin the program to better understand the mineralization and geology."

The three target areas of interest are clustered in the Eastern, Central, and Western parts of the property, as highlighted in Figure 1. Historical work on the Project had identified Tres Marias East as a target area, but the reprocessing of historical geophysics and the completion of additional studies identified stronger anomalies in Tres Marias Central and West which the exploration program will also test.

The planned exploration program will be completed in a phased approach, with the first phase of the program comprising 2,100 m of RC drilling in Tres Marias East. Figure 2 below highlights the collar locations. The initial planned drill holes are aimed at testing different geophysical combinations from the ZTEM reprocessing, UAV MAG survey, and IP/Resistivity survey, as well as the geological model due to their proximity to the Guacate Fault, which has likely imparted some structural control on mineralization. The technical team has begun preparations and mobilization for the exploration program is expected in early May 2023.
