Solaris Announces Significant New Discovery at Warintza South

Solaris Resources Inc. (TSX: SLS; OTCQB: SLSSF) ("Solaris" or the "Company") is pleased to announce a significant new discovery in maiden drilling of the Warintza South target at its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. Highlights are listed below, with corresponding images in Figures 1-4 and detailed results in Tables 1-2. A dynamic 3D model is available on the Company’s website.

Highlights

• SLSS-01 was the first hole ever drilled at Warintza South, which is an entirely separate porphyry deposit, located approximately 3kms south of the Warintza Central zone that has been the focus of the Company’s resource expansion drilling efforts to date

• SLSS-01 was drilled vertically and returned 606m of 0.41% CuEq¹ of continuous porphyry copper mineralization from near surface, within a broader interval of 755m of 0.36% CuEq¹, marking a significant new discovery on the Project

• Warintza South is reflected by a high conductivity anomaly over twice the size of Warintza Central, illustrating the very broad proportions of this newly discovered porphyry system, with approximate dimensions of 2.5km x 2.0km x 0.7km

• SLSS-01 targeted an exposure of leached capping within this anomaly; an ongoing program of detailed sampling, including an additional 265 soil samples and 131 rock samples, significantly expanded the geochemical anomaly and shifted its core to the northeast (Figure 1)

• Follow-up drilling targeting the interpreted core of the porphyry system is set to commence after additional drill platforms are prepared based on this recent mapping and sampling work refining the target and a dedicated exploration camp is set up to support a ramp-up in activities

• Warintza South marks the fourth major copper discovery within the 7km x 5km Warintza porphyry cluster, with the adjacent Yawi and Caya targets still to be tested, as well as other recently generated targets within the broader land package to be revealed in a forthcoming update

Mr. Jorge Fierro, Vice President, Exploration, commented: “We are delighted to have made a significant new discovery at Warintza South, with the first ever hole returning a long interval of well mineralized copper porphyry. The multi-km dimensions of the target present a large-scale opportunity. Interpretation of the drill core together with recent mapping and sampling provide important vectors for follow-up drilling to be completed once additional access and infrastructure are established.” Figure 1 – Plan View

Notes to Figure 4: SLSS-01 core interval from 377.03 to 379.15m, averaging 0.74% Cu, 0.04% Mo and 0.05g/t Au. Quartz-diorite intermineral dike is cutting andestic volcanics. Alteration and mineralization is mainly composed of early-stage, halo-type associations with quartz, anhydrite, chlorite, biotite, epidote, pyrite, chalcopyrite, and magnetite cut by A- and B-type Mo-bearing quartz veinlets.

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.
