Solaris Intersects 626m of 0.50% CuEq From Surface in Expansion Drilling at Warintza East and Identifies Second, Higher Grade Porphyry Center Opening Southern Extension Potential
VANCOUVER, British Columbia, April 03, 2023 (GLOBE NEWSWIRE) -- Solaris Resources Inc. (TSX: SLS; OTCQB: SLSSF) (“Solaris” or the “Company”) is pleased to report assay results from a series of holes aimed at growing mineral resources and the identification of a second, higher grade porphyry center opening up extension potential to the south at the Warintza East discovery within its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. Highlights are listed below, with a corresponding image in Figure 1 and results in Tables 1-2.
Highlights
Warintza East was discovered in July 2021, with only eight holes completed prior to the cut-off for inclusion in the Warintza Central Mineral Resource Estimate (“MRE”)¹ in April 2022. Subsequent drilling has significantly expanded the dimensions of the deposit to the north, east and south, where it remains open. Recent drilling has now validated a southern vector toward stronger soil anomalism, identifying a second porphyry center producing higher grade mineralization and opening up further expansion potential in this direction.
- SLSE-23 was collared in the middle of the Warintza East drill grid and drilled north, returning 626m of 0.50% CuEq² from surface within a broader interval of 746m of 0.46% CuEq², expanding the footprint to the north where it remains open
- SLSE-24 was collared at the southeastern limit of the grid and drilled southwest into an open volume, returning 156m of 0.52% CuEq² from near surface within a broader interval of 410m of 0.30% CuEq², extending mineralization to the southwest where it remains open
- SLSE-20 was collared in the middle of the drill grid and drilled east, returning 292m of 0.45% CuEq² from surface within a broader interval of 900m of 0.30% CuEq², expanding the footprint to the east where it remains open
- SLSE-21 was collared at the southeastern limit of the grid and drilled east, returning 198m of 0.40% CuEq² within a broader interval of 1,040m of 0.33% CuEq² from surface, extending mineralization to the east where it remains open
- SLSE-25 was collared from a new central platform and drilled vertically with a small drill rig specifically used for infill purposes, returning 110m of 0.46% CuEq² from 32m depth within a broader interval, upgrading this area with near surface, high-grade mineralization
- Identification of a second porphyry center in SLSE-28, with visual interpretation suggesting potential for some of the strongest grades to date at Warintza East – the new porphyry center is located south of SLSE-22, which exited a weakly mineralized dyke into stronger mineralization over its final 40m, consistent with increased grades observed from SLSE-16 in this area (192m of 0.70% CuEq² from 350m depth within a broader interval of 712m of 0.45% CuEq² - refer to press release dated January 17, 2023)
Mr. Jorge Fierro, Vice President, Exploration, commented: “Drilling to date confirms Warintza East as a significant porphyry deposit that adjoins Warintza Central and remains open for expansion, with a particular direction of focus to the south where extensional and step-out drilling is targeting higher grade mineralization associated with a newly identified southern porphyry center.”

- Copper-equivalence 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.
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. 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. Details on the surface sampling conducted at the Project are set out in the 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 available on the Company’s SEDAR profile and website. The drillhole data has been verified by Jorge Fierro, M.Sc., DIC, PG, using data validation and quality assurance procedures under high industry standards.

Cautionary Notes and Forward-looking Statements
This document contains certain forward-looking information and forward-looking statements within the meaning of applicable securities legislation (collectively “forward-looking statements”). The use of the words “will” and “expected” and similar expressions are intended to identify forward-looking statements. These statements include statements that recent drilling has now validated a southern vector toward stronger soil anomalism, identifying a second porphyry center localizing higher grade mineralization and opening up further expansion potential in this direction, identification of a second porphyry center in SLSE-28, with visual interpretation suggesting potential for some of the strongest grades to date at Warintza East – the new porphyry center is located south of SLSE-22, which exited a weakly mineralized dyke into stronger mineralization over its final 40m, consistent with increased grades observed from SLSE-16 in this area, and drilling to date confirms Warintza East as a significant porphyry deposit that adjoins Warintza Central and remains open for expansion, with a particular direction of focus to the south where extensional and step-out drilling is targeting higher grade mineralization associated with a newly identified southern porphyry center. Although Solaris believes that the expectations reflected in such forward-looking statements and/or information are reasonable, readers are cautioned that actual results may vary from the forward-looking statements. These statements are based on a variety of assumptions including assumptions made about the Company’s ability to advance exploration efforts at the Warintza Project; the results of such exploration efforts; and the Company’s ability to achieve its growth objectives. These statements also involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements, including the risks, uncertainties and other factors identified in the Solaris Management’s Discussion and Analysis, for the year ended December 31, 2022 available at Furthermore, the forward-looking statements contained in this news release are made as at the date of this news release and Solaris does not undertake any obligation to publicly update or revise any of these forward-looking statements except as may be required by applicable securities laws.
