Highest Grades To Date In Second Porphyry Centre Outside Resource At Warintza East

VANCOUVER - Solaris Resources Inc. announced 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 Estimate (MRE). 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, with assays 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% CuEq from bedrock surface at 8m depth to the end of the hole, with the final 31m averaging 0.76% CuEq. Two new platforms were constructed to the east and west, also outside the MRE, with follow-up drill hole SLSE-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.

Jorge Fierro, Vice President, Exploration, said, “The discovery of a second, significantly higher grade porphyry center at Warintza East is a welcome surprise in our ongoing mineral resource growth drilling program. This new zone offers the potential to rapidly add near surface, high grade mineralization to the deposit that could contribute to future starter pit growth. Moreover, the zone is wide open with step-out and extension drilling coming soon.”
