Solaris Resources Inc. reported assay results from a series of holes aimed at growing mineral resources at the Warintza East discovery within its Warintza Project in southeastern Ecuador. Warintza East was discovered in July 2021, with eight holes covering the overlapping periphery included in the Warintza Central Mineral Resource Estimate (“MRE”)¹ in April 2022. These follow-up drill results significantly expand the drilled dimensions of the Warintza East footprint to the northeast, east and south, with the deposit remaining open in these directions, most importantly towards strong soil anomalism to the south.

SLSE-16 was collared at the eastern limit of the grid and drilled southwest into an open volume, returning 108m of 0.57% CuEq² within a broader interval of 712m of 0.45% CuEq² from surface, extending mineralization to the south and southeast where it remains open; This hole was collared approximately 250m to the southeast of SLSE-13, which previously returned 104m of 0.45% CuEq² from surface within a broader interval of 618m of 0.29% CuEq²; SLSE-17 was collared in the middle of the Warintza East drill grid and drilled southeast into an open volume, returning 144m of 0.52% CuEq² from surface within a broader interval of 914m of 0.40% CuEq², extending mineralization to the east where it remains open; This hole extends the drilled dimensions further to the east beyond SLSE-14, which previously returned 292m of 0.50% CuEq² from near surface within a broader interval of 694m of 0.40% CuEq²; SLSE-19 was collared in the middle of the Warintza East drill grid and drilled northeast into an open volume, returning 270m of 0.40% CuEq² from surface within a broader interval of 580m of 0.31% CuEq², expanding the footprint to the northeast where it remains open; Drilling to date confirms Warintza East as a significant porphyry deposit that adjoins Warintza Central and remains open for expansion, with assays pending from a series of extensional holes to the north, east, south and southeast.
