• SLS-15 reported 1,002m of 0.60% CuEq from surface, showing broad intervals of copper and molybdenum.
• SLS-16 yielded 958m of 0.77% CuEq from near surface, indicating significant mineralization continuity.

Negative

• None.

VANCOUVER, BC, March 22, 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 diamond drilling program at its Warintza Project ("Warintza" or "the Project") in south-eastern Ecuador. 

Highlights are listed below, with corresponding images in Figures 1-2 and detailed results in Tables 1-2. An updated dynamic 3D model is available on the Company's website.

Highlights

• Three additional holes at Warintza Central, as detailed below, have returned long intervals of high-grade mineralization, with the highest grades starting from surface, and extending mineralization between the eastern and western drilling and stepping out to the southwest.
  
  
• SLS-14 was collared on the western side of Warintza Central and drilled into an open volume to the east, returning 922m of 0.94% CuEq¹ (0.79% Cu, 0.03% Mo, and 0.08 g/t Au) from surface, including 850m of 0.98% CuEq¹ (0.82% Cu, 0.03% Mo, and 0.08 g/t Au), significantly extending the limits of mineralization
  
  
• SLS-15 returned 1,002m of 0.60% CuEq¹ (0.52% Cu, 0.01% Mo, and 0.04 g/t Au) from surface, including 694m of 0.67% CuEq¹ (0.57% Cu, 0.02% Mo, and 0.05 g/t Au) within a broader interval of 1,229m of 0.56% CuEq¹ (0.48% Cu, 0.01% Mo, and 0.04 g/t Au), stepping out to the southeast and extending mineralization to depth
  
  
• SLS-16 returned 958m of 0.77% CuEq¹ (0.63% Cu, 0.03% Mo, and 0.06 g/t Au) from near surface, including 486m of 0.84% CuEq¹ (0.70% Cu, 0.03% Mo, and 0.07 g/t Au), extending mineralization between the eastern and western drilling at Warintza Central
  
  
• To date, 20,200 metres have been drilled at Warintza Central in 25 holes of which results have been reported for 16; drilling is ongoing with six rigs currently operating and increasing to 12 by mid-year

Mr. Jorge Fierro, Vice President, Exploration, commented: "Our drilling continues to demonstrate significant extensions of mineralization at Warintza Central with the latest results suggesting the continuity of high-grade mineralization between the eastern and western areas and extending the mineralized envelope to the southeast. Our exploration drilling recently resulted in a new discovery at Warintza West, with maiden drilling targeting new discoveries at Warintza East and South commencing in the second quarter."

(1) No adjustments were made for recovery as the project is an early-stage exploration project and metallurgical data to allow for estimation of recoveries is not yet available. Solaris defines copper equivalent calculation for reporting purposes only. Copper-equivalence calculated as:  CuEq (%) = Cu (%) + 3.33 × Mo (%) + 0.73 × Au (g/t), utilizing metal prices of Cu - US$3.00/lb, Mo - US$10.00/lb and Au - US$1,500/oz.

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.
