November 15, 2021 – Vancouver, B.C. – Solaris Resources Inc. (TSX: SLS; OTCQB: SLSSF) (“Solaris" or the “Company") is pleased to report assay results from a series of additional holes from ongoing resource growth and discovery drilling programs at its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador.

Highlights are listed below, with corresponding images in Figures 1-3 and detailed results in Tables 1-2. A dynamic 3D model is available on the Company’s website.

Highlights

Two additional holes reported in this press release have extended the dimensions of Warintza Central zone to the south and east, with the highest-grade intervals in each hole starting at or near surface (refer to Figures 1 & 2)

Southern extension drilling in SLS-36 together with northern step-out drilling previously reported on October 12 in SLS-32, which returned 618m of 0.48% CuEq¹ from surface, including 372m of 0.64% CuEq¹ from 46m depth, have widened the Warintza Central zone

SLS-35 was collared at the southeastern limit of the Warintza Central grid and drilled into a partially open volume to the east, returning 920m of 0.62% CuEq¹, including 326m of 0.80% CuEq¹ from 50m depth, extending mineralization to the east where it partially overlaps Warintza East

SLS-36 was collared in the middle of the Warintza Central grid and drilled into an open volume to the southeast, returning 1,080m of 0.41% CuEq¹ from surface, including 290m of 0.81% CuEq¹ from 46m depth, extending mineralization by at least 200m to the south where it remains open

To date, 50 holes have been completed at Warintza Central with assays reported for 36 of these

Mr. Jorge Fierro, Vice President, Exploration, commented: “We are pleased to see the continued growth of the Warintza Central zone, with every hole drilled having hit significant mineralization and the dimensions of the zone open and growing to the east, and broadening to the north and south where additional assays are expected soon. Our drilling fleet has now been fully reoriented to pursue aggressive growth and discovery drilling over the balance of the year and into 2022.”

Technical Information and Quality Control & Quality Assurance

Sample assay results have been independently monitored through a quality control/quality assurance (“QA/QC”) 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 Labs in Quito. Sample pulps are sent to ALS Labs 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 Bureau Veritas lab in Lima, Peru. Both ALS Labs and Bureau Veritas lab 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. ZTEM data quality was validated by a qualified external professional using data validation procedures under high industry standards, and the Company therefore did not deem it necessary to have such ZTEM data verified by a Qualified Person. Analytical data for the surface samples collected are from recent interpretations derived from ZTEM data and from previous operators as detailed in the technical report entitled, “Resource Estimate of the Warintza Central Cu-Mo Porphyry Deposit" prepared by Equity Exploration Consultants Inc. with an effective date of December 13, 2019, and available on the Company’s SEDAR profile and website. The drillhole data has been verified by Jorge Fierro, M.Sc., DIC, PG, using data validation and quality assurance procedures under high industry standards.
