Press Releases

February 13, 2023 – Vancouver, B.C. – Solaris Resources Inc. (TSX: SLS; OTCQB: SLSSF) (“Solaris” or “the Company”) is pleased to report updated geochemical sampling and assay results from follow-up holes at Warintza West within its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. Highlights are listed below, with a corresponding image in Figure 1 and detailed results in Tables 1-2.

Highlights

Warintza West, discovered February 2021, is one of four discoveries made to date within the Warintza porphyry cluster and is located 1km west of and outside the Warintza Mineral Resource Estimate (“MRE”)¹. The initial reconnaissance holes from a centralized platform have outlined a broad zone of porphyry mineralization measuring 1200m x 700m that remains open. Subsequent geochemical sampling has provided vectors toward potential higher-grade mineralization to the north for step-out drilling.

• Recent geochemical sampling has identified a new area of strong overlapping copper and molybdenum anomalies to the north measuring approximately 1000m x 500m with soil samples averaging 600 ppm Cu and 80 ppm Mo – this contrasts with the anomaly surrounding the original platform that is defined by strong Mo values at 65 ppm but weaker Cu below 400 ppm

• This new area of strong soil anomalism represents a potential target for higher-grade mineralization beyond the northern margin of prior exploration drilling (refer to press releases dated Oct 13, 2022 and Feb 16, 2021), including:
  • SLSW-07 (drilled north) returned 686m of 0.46% CuEq²
  • SLSW-04 (drilled northeast) returned 264m of 0.44% CuEq²
  • SLSW-01 (drilled northwest) returned 260m of 0.42% CuEq³

• New drill results returned to the south, include SLSW-13, which was drilled southwest and returned 320m of 0.50% CuEq² from near surface within a broader interval of 496m of 0.40% CuEq², extending mineralization to the south where it remains open, and requires step-out drilling

• This hole expands on previously reported SLSW-10, which was drilled from the same platform to the southwest and returned 220m of 0.41% CuEq² from near surface (refer to press release dated Oct 13, 2022)

Mr. Jorge Fierro, Vice President, Exploration, commented: “First pass reconnaissance drilling at Warintza West outlined a broad zone of porphyry mineralization, with subsequent sampling identifying new potential for higher-grade mineralization to the north for future step-out drilling. The ongoing drill program is targeting MRE growth within the high-grade starter pit at Warintza Central, where results are expected shortly, and expanding the Warintza East discovery which adjoins Warintza Central.”

Endnotes

1. Refer to technical report titled, “NI 43-101 Technical Report for the Warintza Project, Ecuador” with an effective date of April 1, 2022, prepared by Mario E. Rossi and filed on the Company’s SEDAR profile at www.sedar.com.
2. Copper-equivalence for the MRE and drill holes SLSW 2-13 calculated as: CuEq (%) = Cu (%) + 4.0476 × Mo (%) + 0.487 × Au (g/t), utilizing metal prices of US$3.50/lb Cu, US$15.00/lb Mo, and US$1,500/oz Au, and assumes recoveries of 90% Cu, 85% Mo, and 70% Au based on preliminary metallurgical test work.
3. Copper-equivalence calculated as: CuEq (%) = Cu (%) + 3.33 × Mo (%) + 0.73 × Au (g/t), utilizing metal prices of US$3.00/lb Cu, US$10.00/lb Mo, and US$1,500/oz Au. No adjustments were made for recovery prior to the updated MRE, as the metallurgical data to allow for estimation of recoveries was not yet available. Solaris defined CuEq for reporting purposes only.

Technical Information and Quality Control & Quality Assurance

Sample assay, steam sediment, soil and rock 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. In addition, selected pulp check samples are sent to Bureau Veritas lab in Lima, Peru. Both ALS Labs and Bureau Veritas lab are independent of Solaris. 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, and the Company therefore did not deem it necessary to have such ZTEM data verified by a Qualified Person. The technical data has been verified by Jorge Fierro, M.Sc., DIC, PG, using data validation and quality assurance procedures under high industry standards.

Qualified Person
