SOLARIS REPORTS 54M OF 0.80% CUEQ FROM SURFACE IN NORTHWEST STEP-OUT AT WARINTZA CENTRAL; 268M OF 0.60% CUEQ WITHIN 830M AVERAGING 0.50% CUEQ IN NORTHEAST STEP-OUT

Solaris Resources Inc. has released assay results from a series of holes aimed at growing the indicative starter pit within the Warintza Central zone at its Warintza project in southeastern Ecuador. Highlights are listed herein, with detailed results in an attached table.

Highlights

Mineral resource expansion drilling continues to target growth of the indicative starter pit, an area of near-surface, high-grade mineralization estimated at 180 million tonnes at 0.82 per cent copper equivalent (indicated) and 107 million tonnes at 0.73 per cent CuEq (inferred) in the Warintza mineral resource estimate (MRE). Recent drilling has expanded the northeast extension zone to the north-northeast, where further stepouts are planned, while a 250-metre stepout on the opposite side of Warintza Central has expanded the zone to the northwest and opened up new potential:

• SLS-72 was collared from a newly constructed stepout platform 200 m to the northeast, returning 268 m of 0.60 per cent CuEq within a broader interval of 830 m averaging 0.50 per cent CuEq from 48 m depth, extending the zone to the northeast, where it remains open.
• SLS-71 was collared from the same platform within the northeast extension zone and drilled northwest into a partially open volume, returning 212 m of 0.60 per cent CuEq, including 50 m of 0.87 per cent CuEq, within a broader interval of 494 m of 0.42 per cent CuEq from near surface.
• SLS-73 was collared from another newly constructed stepout platform 250 m to the north, returning 26 m of 0.96 per cent CuEq from near surface and 128 m of 0.60 per cent CuEq within a broader interval, extending the zone to the northeast, where it remains open.
• These three holes expand the northeast extension zone to the east and northeast, where two additional 200 m stepout platforms have been planned for construction to test the potential extension of the zone beneath shallow saprolitic cover.
• On the opposite side of Warintza Central, SLS-74 was collared from a newly constructed platform stepping out 250 m to the northwest of the existing drill grid to test the potential extension of high-grade, near-surface mineralization -- it returned 54 m of 0.80 per cent CuEq from surface within a broader interval of 224 m of 0.41 per cent CuEq.
• SLS-74 includes lower-grade mineralization within a porphyritic granodiorite modelled as the northwestern contact of Warintza Central -- continuing mapping and sampling aim to assess the potential for better-developed mineralization higher up in this intrusive phase in the 700 m gap to Warintza West.
• Additional assays are expected soon from drilling targeting further growth at Warintza East, follow-up drilling at the recent high-grade Warintza Southeast discovery and the new Patrimonio discovery.

Technical information and quality assurance/quality control

Sample assay results have been independently monitored through a quality control/quality assurance program that includes the insertion of blind certified reference materials (standards), blanks and field duplicate samples. Logging and sampling are completed at a secured company facility located in Quito, Ecuador. Drill core is cut in half on site, and samples are securely transported to ALS in Quito. Sample pulps are sent to ALS in Lima, Peru, and Vancouver, Canada, for analysis. Total copper and molybdenum contents are determined by four-acid digestion with AAS finish. Gold is determined by fire assay of a 30-gram charge. In addition, selected pulp check samples are sent to the Bureau Veritas laboratory in Lima, Peru. Both ALS and Bureau Veritas are independent of Solaris. Solaris is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein. The drill hole data have been verified by Jorge Fierro, MSc, DIC, PG, using data validation and quality assurance procedures under high industry standards.
