Solaris Resources Inc. reported additional drill results as its 2024 drilling program ramps up and a major expansion of planned meterage from 30km to 60km in this program. Latest drilling results include SLSE-33, collared on the southern margin of Warintza Southeast and drilled at a steep inclination northeast, returning 81m of 0.73% CuEq from near surface within a broader interval of 5 millionm of 0.50% CuEq from surface and bottoming in mineralization. SLSE-35 was collared from a central platform at Warintza East and drilled east, returning 189m of 0.50%CuEq from surface within a broader interval of 580m of 0.42% CuEq and remaining open in mineralization, with the last 10m averaging 0.41% CuEq.

Major expansion of 2024 drilling program from 30km to 60km supported by the proceeds of the recently closed financing and significant productivity improvements to target open lateral extensions of mineralization beyond the pit, including into the Patrimonio target area, improve drilling density and support technical studies. Continued drilling ramp up with six rigs completing 7.7 km in May and a seventh rig expected soon to challenge the prior peak drilling rate achieved with 12 rigs in 2021 primarily as a result of improved logistics from infrastructure investments, construction of on-site facilities and trail networks connecting new drilling platform locations together with process optimization. Updated mineral resource estimate on track for release early July.

Ongoing regional exploration efforts have expanded the footprint of epithermal-style mineral alteration from the Caya area into the adjacent Mateo porphyry target 6km east of the Warintza cluster, while field crews have also been active on the newly-acquired adjacent claims. Details on the surface sampling conducted at the Project are set out in the technical report titled, NI 43-101 Technical Report for the Warintza Project, Ecuador (Amended)" with an effective date of April 1, 2022, prepared by Mario E. Rossi and available on the Company's SEDAR+ profile and website. These statements include statements that SLSE-35 remains open in mineralization, a major expansion of 2024 drilling program from30km to 60km to target open lateral extensions of Mineralization, a major expansion of 2022 drilling program from 30km to60km to target open lateral extensions.
