Solaris Reports 1,004m of 0.71% CuEq From Surface, Expands Limits of Warintza Central

VANCOUVER, Nov. 23, 2020 - Solaris Resources Inc. (TSXV: SLS) ("Solaris" or the "Company") is pleased to report assay results from three additional holes from the ongoing 40,000-meter (m) diamond drill program at its Warintza Project ("Warintza" or "the Project") in south-eastern Ecuador.

Highlights from the recent drilling are listed below and summarized in Tables 1 and 2.

Highlights

• Three additional holes, as detailed below, have returned long intervals of high-grade mineralization from surface, well beyond the 200m average depth-extent of historical drilling that the Warintza Central resource estimate is based upon (refer to Images 1-3)
• SLS-04 returned 1,004m of 0.71% CuEq¹ (0.59% Cu, 0.03% Mo, and 0.05 g/t Au) from surface, including 824m of 0.77% CuEq¹ (0.64% Cu, 0.03% Mo, and 0.05 g/t Au), far beyond the 138m length of the corresponding historical hole, and bottoming in mineralization at the depth-capacity of the rig
• SLS-05 returned 918m of 0.50% CuEq¹ (0.43% Cu, 0.01% Mo, and 0.04 g/t Au), including 306m of 0.62% CuEq¹ (0.52% Cu, 0.02% Mo, and 0.04 g/t Au), extending mineralization to the southwest at depth where it entered a zone of stronger mineralization at the bottom of the hole
• SLS-06 returned 884m of 0.62% CuEq¹ (0.50% Cu, 0.03% Mo, and 0.04 g/t Au), significantly extending mineralization to depth
• The first detailed geophysical survey in the history of the Warintza property has been completed, with encouraging early results and final interpretation expected to be completed by year-end

Mr. Daniel Earle, President and CEO, commented: "Warintza Central continues to demonstrate the potential to become a large, high-grade, open pit copper porphyry deposit, with the limits of mineralization yet to be found. We recently completed the first modern geophysical survey in the history of the property to aid targeting within the 5km by 5km Warintza copper porphyry cluster and series of multi-km gold anomalies to the northeast. Preliminary results have revealed new targets, most immediately the possible extension of Warintza Central to the south of our current drilling."

Mr. Jorge Fierro, Vice President, Exploration, commented: "Our drilling continues to demonstrate major extensions of mineralization to depth at Warintza Central and we've added a more powerful rig to test this with capacity of over 1,500m. SLS-05 also extended mineralization to the southwest at depth. This vector may eventually connect to the El Trinche zone, which presents as a 500m by 300m area of stockwork veining at surface with chip samples ranging from 0.2%-0.8% Cu, approximately 400m south of the limit of surface mineralization at Warintza Central."

Warintza Central is presently defined by a pit-optimized Mineral Resource estimate of 124 Million tonnes of Inferred Resources grading 0.70% CuEq² (0.56% Cu, 0.03% Mo and 0.1 g/t Au), based on historic drilling totaling less than 7,000m and averaging less than 200m in depth. The resource is open laterally and at depth and is set within the 5km-long Warintza trend of porphyry mineralization.

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. ALS Labs is independent from Solaris. In addition, selected pulp check samples are sent to Bureau Veritas lab in Lima, Peru. 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.
