Solaris Reports 1,029m of 0.73% CuEq From Surface, Expands Warintza Central to +1,100m Strike; Maiden Drilling Set to Commence at Warintza East

VANCOUVER, BC, May 26, 2021 /PRNewswire/ - Solaris Resources Inc. (TSX: SLS) (OTCQB: SLSSF) ("Solaris" or the "Company") is pleased to report assay results from a series of additional holes from the ongoing resource growth and discovery drilling programs at its Warintza Project ("Warintza" or "the Project") in south-eastern 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 and will be updated for the latest results.

Highlights

• Three additional holes at Warintza Central, as detailed below, have extended the drill defined envelope of high-grade mineralization to the east and west over a strike length of over 1,100m and open and to a depth up to 1,200m, with the highest-grade mineralization starting at surface
  
  
• SLS-21 was collared on the eastern side of Warintza Central and drilled into an open volume to the east, returning 1,029m of 0.73% CuEq¹, including 420m of 0.83% CuEq¹ from surface, extending the limits of mineralization to the east, with the hole terminating prematurely in mineralized porphyry
  
  
• SLS-22 was collared on the north-western side of Warintza Central and drilled into an open volume to the west, returning 238m of 0.68% CuEq¹, including 100m of 0.77% CuEq¹, extending the limits of mineralization in this direction
  
  
• SLS-23 was collared on the south-western side of Warintza Central and drilled to the west, returning 548m of 0.42% CuEq¹, including 352m of 0.46% CuEq¹ from surface, extending the limit of mineralization in this direction
  
  
• Maiden drilling is set to commence at Warintza East, which is one of the five main targets within the 5km x 5km cluster of copper porphyries identified on the property and has a similar geochemical and geophysical expression as Warintza Central
  
  
• To date, 31 holes have been drilled at Warintza Central with results reported for 22 of these. Unusually heavy rain in Ecuador has significantly impacted the pace of drilling productivity and platform construction over recent months, however weather conditions are now sporadically improving and the planned ramp-up of drilling activities is expected to resume

Mr. Jorge Fierro, Vice President, Exploration, commented: "Our latest drilling continues to expand Warintza Central towards our goal of defining a large, high-grade, open pit resource supported by a robust dataset. The first-ever drill program set to commence at Warintza East is a major milestone in our exploration program, and we note the similarity of the target to Warintza Central in geochemical and geophysical expression."

Warintza East

Warintza East is located approximately 1km east of Warintza Central at slightly lower elevation with gentler topography. The first hole, SLSE-01, is being collared in weathered porphyry stockwork mineralization uncovered by earthworks during drilling platform construction.

The target is defined by overlapping copper and molybdenum anomalies, measuring approximately 1,200m in diameter, with similar values to Warintza Central. Importantly, the corresponding high-conductivity anomaly extends continuously from Warintza Central through the target to the east (refer to Figure 1).

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.

Qualified Person

The scientific and technical content of this press release and the sampling, analytical and test data underlying the scientific and technical content has been compiled, reviewed, approved, and verified by Donald Taylor, MSc., PG, Director of Solaris who is a "Qualified Person" as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects. Donald Taylor is a Registered Professional Geologist through the SME (registered member #4029597). The data was verified using data validation and quality assurance procedures under high industry standards. ZTEM data quality was validated by a qualified external professional.
