Solaris Reports 1,000m of 0.81% CuEq From Surface; Broadens Width of Warintza Central to North in 165m Step Out Hole

VANCOUVER, Oct. 12, 2021 - Solaris Resources Inc. (TSX: SLS) (OTCQB: SLSSF) ("Solaris" or the "Company") is pleased to report the latest assay results from ongoing resource expansion drilling 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

• Three additional holes at Warintza Central, as detailed below, have extended the drill defined envelope of high-grade mineralization to the north, northeast and south, with the highest-grade mineralization encountered in all holes starting at or near surface (refer to Figures 1 & 2)

• SLS-30 was collared in the western portion of the Warintza Central grid and drilled into a partially open volume to the north, returning 372m of 0.82% CuEq¹ from surface, including 264m of 0.97% CuEq¹ from 42m depth, extending mineralization in this direction

• SLS-31 was collared in the middle of Warintza Central and drilled into an entirely open volume to the southeast, returning 1,000m of 0.81% CuEq¹ from near surface, including 768m of 0.90% CuEq¹ from 44m depth, extending mineralization to the south in this area

• SLS-32, stepped out approximately 165m northeast beyond the northern limit of drilling and drilled vertically into an open volume, returning 618m of 0.48% CuEq¹ from surface, including 372m of 0.64% CuEq¹ from 46m depth, broadening the width of the zone to the north

• To date, 44 holes have been completed at Warintza Central with assays reported for 32 of these

Mr. Jorge Fierro, Vice President, Exploration, commented: "Warintza Central continues to expand, with the limits of the zone to the north, south and east yet to be found. Drilling planned over the coming months is focused on further extensional and step-out drilling, including establishing the potential link to the recently-discovered Warintza East zone, and discovery drilling at the other well-defined targets within the 7km x 5km Warintza cluster of porphyries."

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. 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.
