July 09, 2024 – Vancouver, B.C. – Solaris Resources Inc. (TSX: SLS; NYSE: SLSR) (“Solaris” or the “Company”) is pleased to report drill results from the ongoing 2024 drilling program at its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. These include the final assays for inclusion in the updated mineral resource estimate which is expected to be released this month. Highlights are listed below with a corresponding image in Figure 1 and results in Tables 1-2.
Highlights
- SLSE-36 was collared at the southeasternmost platform at Warintza Southeast and returned 148m of 0.72% CuEq¹ within a broader interval of 325m of 0.51% CuEq¹ from surface and remains open in strong mineralization, with the final 34m averaging 0.90% CuEq¹
- SLS-77 was collared on the northern boundary of the Northeast Extension of Warintza Central and returned 108m of 0.70% CuEq¹ from near surface within a broader interval of 273m of 0.57% CuEq¹ from surface
- SLS-78 was collared from a new platform 100m to the west and drilled west through leached cap before returning 78m of 0.70% CuEq¹ within a broader interval of 114m of 0.65% CuEq¹ from 72m depth and then entering low grade granodiorite
- SLS-79 was collared from the same platform and drilled west at steep inclination, returning 78m of 0.60% CuEq¹ from near surface within a broader interval of 248m of 0.50% CuEq¹, ending in strong mineralization
- SLST-03 was collared approximately 300m south of Warintza Central at the Trinche platform and drilled northwest into an open volume to convert undefined waste within the expected pit shell, returning 312m of 0.62% CuEq¹ within a broader interval of 1,028m of 0.30% CuEq¹ from surface
- Patrimonio hole 04 consistent with 01 and 02 intersected an approximately 150m thick tabular zone of replacement mineralization dipping shallowly to the west for which the source has not yet been encountered. SLSP-03 was collared at higher elevation and intersected a low grade layer in the host lava sequence before passing into a barren, post-mineral porphyry that intruded and displaced the targeted mineralized layer. Mineral alteration zoning and geochemistry suggests that the core of the mineralized system lies to the south
- 2024 drill program was recently expanded to 60,000m comprising 140 holes from 80 platforms providing significantly improved drilling coverage with 27,000m in 74 holes completed to the end of June, with seven rigs targeting >8km of drilling in July due to improved site logistics from infrastructure development at site
- Ongoing drilling is focused on Patrimonio exploration, resource extension at Warintza Southeast, and infill and technical drilling to support the PFS in H2/25, including geotechnical holes which are expected to fulfill a dual role in providing information to aid in the understanding of the geology of the Caya-Mateo epithermal gold and silver target area

Notes to table: True widths are interpreted to be very close to drilled widths due to the bulk-porphyry style mineralized zones at Warintza.

Endnotes
- 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 on site. 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. 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 (Amended)” 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.
