Solaris Resources Inc. announced assay results confirming the discovery of a second porphyry center featuring the highest grades to date at Warintza East, with strong mineralization starting from bedrock surface extending to the end of the hole. The new zone is open to the east, west, south and at depth, with follow-up drilling already underway at this important new discovery at the Warintza Project in southeastern Ecuador. Warintza East was discovered in July 2021, with eight drill holes included in the Warintza Central Mineral Resource Estimate¹ in April 2022.

Subsequent drilling has significantly expanded the dimensions of the deposit, with ongoing drilling targeting further mineral resource growth. The latest drilling made an important discovery of a second, more intensely-mineralized porphyry center located outside the MRE, approximately 350m south of the original discovery, withassays now confirming the highest grades encountered at Warintza East to date. SLSE-28 was collared to the south of the Warintza East drill grid and drilled vertically to the limit of the KD-200 rig, returning 301m of 0.65% CuEq² from bedrock surface at 8m depth to the end of the hole, with the final 31m averaging 0.76% CuEq².

Two new platforms were constructed to the east and west, also outside the MRE, with follow-up drill holeSLSE-29 testing the southeast extension up to 200m to the east now completed and SLSE-30 in progress testing the potential to the west. SLSE-29 and SLSE-30 were both drilled with KD-200 rigs to allow for the rapid expansion of this emerging zone of near surface, high grade mineralization, with follow-up deeper drilling planned with larger capacity KD-1400 rigs. The new zone is wide open and additional follow-up drilling is planned to test the potential for lateral expansion, focusing on vectors to the south and southeast where new step-out platforms are under construction.
