Solaris Resources Significantly Expands Warintza East Discovery

Solaris Resources Inc. (TSX: SLS) is pleased to report assay results from a series of holes aimed at delineating resources at the Warintza East discovery on its Warintza Project in southeastern Ecuador. In July 2021, Warintza East was discovered, and in April 2022, the Warintza Central Mineral Resource Estimate included eight holes covering the overlapping perimeter. The follow-up drilling results significantly expanded the drilled dimensions of Warintza East to the east and southwest. At the same time, the deposit remained open to strong soil anomalism to the northeast and southeast. 

Jorge Fierro, Exploration Vice President, stated, “According to Mr. Fierro, Warintza East represents a significant resource opportunity since only a small percentage of the area has been drilled. Extensional and step-out drilling will be conducted to the east and southeast, with a 400-meter step-out platform located on the southern edge of the drilling grid targeting strong soil anomalies.”


During the middle of the Warintza East grid, SLSE-15 was collared and drilled east into a partially open volume, returning 204m of 0.60% CuEq within a broader interval of 910m of 0.40% CuEq from the near-surface, extending mineralization to the east where it remains open. On the other hand, SLSE-14 was stepped out roughly 250m from the eastern edge of the grid and drilled northwest into an open volume, returning 292m of 0.50% CuEq within a broader interval of 693m of 0.40% CuEq from the near-surface, extending mineralization in this direction where it remains open. SLSE-12 was collared at the grid’s eastern border and drilled southwest into an open area, returning 48m of 0.53% CuEq within a broader interval of 508m of 0.40% CuEq from the surface, extending mineralization in this direction. SLSE-13 was collared from the same location and drilled into an open area to the southwest, returning 104m of 0.45% CuEq within a broader interval of 618m of 0.29% CuEq from the surface, expanding the footprint to the south where it remains open. In the overlapping area with Warintza Central, SLSE-10 and SLSE-11 were collared and drilled northwest into partially open volumes, returning 282m of 0.53% CuEq and 270m of 0.55% CuEq, respectively, from near-surface intervals. Warintza East has been confirmed as a significant porphyry deposit, with assays pending from a series of extensional holes to the northeast, east, and south. Multiple expansion areas remain open.

Technical Information and Quality Control & Quality Assurance

Quality control/quality assurance (“QA/QC”) programs monitor the accuracy of data and certify reference materials (standards), blanks, and field duplicates as part of the quality control process. A secured Company facility in Quito, Ecuador, collects, logs, and samples the data. After drilling, the sample pulps are securely transported to ALS Labs, where they are analyzed by ALS Labs in Quito and by ALS Labs in Lima, Peru, and Vancouver, Canada. After the core is split in half on site, the sample pulps are sent to ALS Labs in Lima, Peru, and Vancouver, Canada, for analysis. In addition, the Bureau Veritas laboratory in Lima, Peru, analyzed certain pulp check samples. Quality assurance/quality control programs are independent of Solaris, and Solaris is unaware of any drilling, sampling, recovery, or other factors that could significantly affect the accuracy or reliability of the data reported here. The Company did not feel it necessary to have the ZTEM data verified by a Qualified Person, as it was validated by an external specialist using industry-standard data validation processes. The technical report “NI 43-101 Technical Report for the Warintza Project, Ecuador” by Mario E. Rossi, dated April 1, 2022, and available on the Company’s SEDAR page and the website, describes the surface samples collected at the Project. Jorge Fierro, M.Sc., DIC, PG, verified the drill hole data using industry-quality data validation and assurance procedures.
