Solaris Reports 475m of 1.03% CuEq from Surface in New Drilling as Further Productivity Gains Drive Record 10km Drilled in August

September 19, 2024 Quito, Ecuador Solaris Resources Inc. (TSX: SLS; NYSE: SLSR) (“Solaris” or the “Company”) is pleased to report assay results from its ongoing 60,000m 2024 drilling program that aims to target open extensions of mineralization while upgrading mineral resources and converting waste at its Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. Highlights are listed below with detailed results in Figure 1 and Tables 1-2.

Highlights

Drill results continue to build on the 2024 Mineral Resource Estimate¹ (“MRE”), with this release highlighted by intercepts of high-grade mineralization outside of the MRE in the northwest and southeast sectors. Some of these holes also significantly improve upon modelled grades in sparsely drilled areas.

Northwest Sector:

  • SLS-100 (drilled southeast): 427m of 1.11% CuEq² within 475m of 1.03% CuEq² from surface
  • SLS-99 (drilled southwest): 105m of 1.00% CuEq² within 246m of 0.75% CuEq² from surface
  • SLS-96 (drilled southeast): 78m of 0.71% CuEq² within 288m of 0.47% CuEq² from surface
  • SLS-97 (drilled west): 75m of 0.60% CuEq² within 308m of 0.36% CuEq² from surface

Holes SLS-96, SLS-97 and SLS-99 added new high-grade mineralization partially outside of the MRE while SLS-100 improved upon the modelled grade in its vicinity. These holes were located in the northwest sector where mineralization has now been extended to the contact with a tabular granodiorite that shapes the northwestern pit wall. Step-out exploration drilling is now testing the potential for mineralization within a large area of undrilled soil anomaly on the far side of this body.

Southeast Sector:

  • SLSE-50 (southwest): 84m of 0.70% CuEq² within 445m of 0.53% CuEq² from surface
  • SLSE-45 (drilled east): 285m of 0.63% CuEq² within 399m of 0.58% CuEq² from surface
  • SLSE-47 (drilled southwest): 210m of 0.58% CuEq² within 399m of 0.42% CuEq² from surface
  • SLSE-46 (drilled south): 75m of 0.73% CuEq² within 400m of 0.34% CuEq² from surface

Holes SLSE-45, SLSE-46, SLSE-47, and SLSE-50 added new high-grade mineralization partially outside of the MRE while SLSE-45 and SLSE-46 improved upon modelled grades in their vicinity. Mineralization remains open to the southeast for approximately 600m within a large 0.8km x 0.8km soil anomaly that defines the target opportunity in this direction.

New Drilling Record:

Warintza continues to see gains from significant infrastructure investment at site, with the next phase of construction underway. These improvements have supported the Project team achieving a new monthly drilling record of 10km (8 rigs) in August – well above the prior monthly peak of 8km (12 rigs) set in 2021. The Company is now well positioned to exceed the 60,000m of drilling planned this year.

  2. Copper-equivalence grade calculation for reporting assumes metal prices of US$4.00/lb Cu, US$20.00/lb Mo, and US$1,850/oz Au, and recoveries of 90% Cu, 85% Mo, and 70% Au based on preliminary metallurgical testwork. CuEq formula: CuEq (%) = Cu (%) + 5.604 × Mo (%) + 0.623 × Au (g/t).

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 secure 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. Heliborne magnetic, LIDAR and other layers of data quality for Warintza district exploration were validated by a qualified external professional using data validation procedures under high industry standards and the Company therefore did not require such data to be further verified by a “Qualified Person” as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects. The remaining scientific and technical information, including the drillhole data, has been verified by Jorge Fierro, M.Sc., DIC, PG, using data validation and quality assurance procedures under high industry standards. The verification activities included a search for factual errors, completeness of the lithological and assay data, and suitability of the primary data. As part of the database verification activities, the assay information and certificates obtained directly from the analytical laboratory have been examined as well.

Qualified Person

The scientific and technical content of this press release has been reviewed and approved by Jorge Fierro, M.Sc., DIC, PG, Vice President Exploration of Solaris who is a “Qualified Person” as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects.  Jorge Fierro is a Registered Professional Geologist through the SME (registered member #4279075).
