Solaris Reports 1,000m of 0.60% CuEq From Surface, Extending Warintza Central to 1,250m Strike Length

VANCOUVER, BC, July 7, 2021 /PRNewswire/ - 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 and will be updated to incorporate the most recent results.

Highlights

• Additional drill holes have extended the strike length of Warintza Central to 1,250m, exceeding the original scope of planned resource drilling across 1,000m of strike length
  
  
• Warintza Central remains open, with the most recent holes extending mineralization to the east returning some of the strongest intervals reported to date, including SLS-21 (1,029m of 0.73% CuEq¹ from surface, as previously released on May 26, 2021) and SLS-26 reported below
  
  
• Drilling has consistently shown the highest-grade mineralization at Warintza occurs at or near surface, which lends itself to establishing a robust mine plan with elevated grades benefitting the early years of mine life
  
  
• SLS-24 was collared at the southeastern limit of the Warintza Central grid and drilled into an entirely open area due east, returning 952m of 0.62% CuEq¹, including 502m of 0.67% CuEq¹ from 10m depth, expanding mineralization into this area
  
  
• SLS-25 was collared on the western limit of the grid and drilled into a partially-open volume to the southwest, returning 382m of 0.77% CuEq¹, including 230m of 1.06% CuEq¹, infilling and extending mineralization in this area
  
  
• SLS-26 was collared on the eastern side of the grid and drilled to the northeast, returning 1,000m of 0.60% CuEq¹, including 786m of 0.67% CuEq¹ from surface, extending the limits of mineralization more than 150m in this direction
  
  
• To date, 36 holes have been completed at Warintza Central with full assay results reported for 26. Weather conditions have continued to improve at site supporting the continued ramp-up of drilling activities, with increased productivity expected through the third quarter 

Mr. Jorge Fierro, Vice President, Exploration, commented: "Our latest drilling has continued to expand the footprint of Warintza Central toward our goal of defining a large, high-grade, open pit resource. With these holes, the drilled strike length has grown to the east beyond the original limits of planned resource drilling and remains open toward Warintza East, where results of maiden drilling are expected soon."

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. 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.
