September 28, 2020 – Vancouver, B.C. – Solaris Resources Inc. (TSXV: SLS) ("Solaris" or the "Company") is pleased to report assay results for the second and third drill holes from the ongoing 40,000 metre (m) diamond drill program at its Warintza Project (“Warintza” or “the Project”) in south-eastern Ecuador. The drill program aims to expand the lateral footprint and depth extent of the high-grade Warintza Central zone, discovered by the late David Lowell in 2000.

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

Highlights

SLS-02 returned a consistent, high grade interval from surface of 660m of 0.97% CuEq¹ (0.79% Cu, 0.03% Mo, and 0.1 g/t Au), confirming the significant extension of mineralization relative to historical drilling first reported in SLS-01 (see August 10, 2020 Press Release)
SLS-03 returned a much longer and open interval of high-grade mineralization from surface to the depth capacity of the drill rig: 1,010m of 0.71% CuEq¹ (0.59% Cu, 0.02% Mo, and 0.1 g/t Au), including 716m of 0.75% CuEq¹ (0.63% Cu, 0.02% Mo, and 0.1 g/t Au)
SLS-03 was collared approximately 426m east of the first two holes and greatly improves upon the depth extent of known mineralization, with historical drilling averaging less than 200m in depth (see Images 1 & 2)
Geological interpretation suggests that the mineralization encountered to date is representative of the ‘outer halo’ of the porphyry system, with the higher-grade core to be vectored toward with future drilling locations
The first three holes were drilled with one rig; drilling is now ongoing with two rigs and a third rig with greater drilling capacity is due imminently
Mr. Jorge Fierro, Vice President, Exploration, commented, “The third hole stepped out over 400m to the east of the first drilling location within Warintza Central (see Image 3) and provided further evidence of the depth extent of the system, which still remains open. In addition, the results continue to support our interpretation that our drilling is confined to the ‘outer halo’ of the porphyry system. Additional drilling locations will be required to triangulate the high-grade core.”

Mr. Richard Warke, Executive Chairman, commented, “Warintza Central continues to demonstrate the potential to become a large, high-grade open pit copper porphyry deposit, which is a rarity in the modern context of the industry. As strong as results are, what’s extremely exciting is that we are at a very early stage of exploration on the property and drilling has only occurred at Warintza Central. The trend is 5km long and includes Warintza East, West and South, all of which are approximately of equal footprint and West and South have yielded higher soil and chip samples.”

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 entirely open laterally and at depth and is set within the 5 km-long Warintza trend of porphyry mineralization. There has been no drilling outside of the Warintza Central area.

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.
