Solaris Adds to Near Surface, High-Grade Northeast and Southeast Extensions, Priorities for Further Growth Beyond Mineral Resource

April 4, 2022 Vancouver, B.C. Solaris Resources Inc. (TSX: SLS; OTCQB: SLSSF) (“Solaris” or “the Company”) is pleased to report assay results from a series of additional holes from mineral resource growth drilling at 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. A dynamic 3D model is available on the Company’s website and will be updated to incorporate the most recent results.

Highlights

Additional drilling has expanded the growing northeast extension area, which remains open with follow-up and step-out drilling underway. This zone is characterized by near surface, high-grade mineralization, as detailed below, at the northeastern limit of drilling at Warintza Central and represents a priority target for further growth.

  • SLS-54 was collared at the northeastern limit of the grid and drilled into an open volume near surface, returning 356m of 0.73% CuEq¹ from 50m depth within a broader interval of 1,093m of 0.56% CuEq¹ from surface
  • This follows from near surface, high-grade mineralization previously reported (refer to press releases dated February 28, 2022, December 14, 2021 and October 25 & 12, 2021) from:
    • SLS-49 - 396m of 0.70% CuEq¹ from 50m depth within 817m of 0.60% CuEq¹
    • SLS-48 - 100m of 1.64% CuEq¹ from 50m depth within 852m of 0.56% CuEq¹
    • SLS-42 - 740m of 0.60% CuEq¹ from 52m depth within 906m of 0.53% CuEq¹
    • SLS-38 - 244m of 0.70% CuEq¹ from 58m depth within 822m of 0.35% CuEq¹
    • SLS-34 - 242m of 0.67% CuEq¹ from 52m depth within 660m of 0.47% CuEq¹
    • SLS-32 - 372m of 0.64% CuEq¹ from 46m depth within 618m of 0.48% CuEq¹
  • Follow-up drilling from existing platforms is underway, with a 260m northeast step-out platform recently completed and a second platform stepping out further to the northeast under construction

Additional drilling has expanded the growing southeast extension area, which remains open in near surface, high-grade mineralization.

  • SLS-52 was collared on the eastern side of the grid and drilled southeast into an open volume near surface, returning 482m of 0.62% CuEq¹ from 96m depth, within a broader interval of 977m of 0.45% CuEq¹ from near surface that infilled drilling at depth
  • SLS-53 was collared from a southeastern platform and drilled south into an open volume near surface, returning 176m of 0.78% CuEq¹ from 16m depth, within a broader interval of 957m of 0.46% CuEq¹ from 10m depth that infilled drilling at depth
  • This follows from near surface, high-grade mineralization previously reported (refer to press releases dated February 28, 2022, December 14, 2021 and November 15, 2021) from:
    • SLS-45 - 236m of 0.56% CuEq¹ from 44m depth within 564m of 0.41% CuEq¹
    • SLS-39 - 368m of 0.73% CuEq¹ from 90m depth within 915m of 0.56% CuEq¹
    • SLS-35 - 326m of 0.80% CuEq¹ from 50m depth within 920m of 0.62% CuEq¹
  • Additional platform construction to support follow-up and step-out drilling to test the further southeast extension of near surface, high-grade mineralization is planned, following the release of the updated mineral resource estimate
  • SLS-51 was collared from the south-central portion of the grid and drilled east into an open volume at surface, returning 918m of 0.50% CuEq¹ from 130m depth within a broader interval of 1,012m of 0.47% CuEq¹ from near surface that infilled drilling at depth

Updated Warintza Central Mineral Resource Estimate expected to be issued in April.

To date, 62 holes have been completed at Warintza Central with assays reported for 54 of these.

Mr. Jorge Fierro, Vice President, Exploration, commented: “These final holes expand on two key growth areas with near surface, high-grade mineralization on the edge of resource drilling that remains open. These holes will be included in the forthcoming resource update; further extensions to the northeast and southeast represent priority targets for further growth with step-out drilling commencing shortly.”

(1) No adjustments were made for recovery as the project is an early-stage exploration project and metallurgical data to allow for estimation of recoveries is not yet available. Solaris defines copper equivalent calculation for reporting purposes only. Copper-equivalence calculated as:  CuEq (%) = Cu (%) + 3.33 × Mo (%) + 0.73 × Au (g/t), utilizing metal prices of Cu - US$3.00/lb, Mo - US$10.00/lb and Au - US$1,500/oz.

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. Analytical data for the surface samples collected are from recent interpretations derived from ZTEM data and from previous operators as detailed in the technical report entitled, “Resource Estimate of the Warintza Central Cu-Mo Porphyry Deposit" prepared by Equity Exploration Consultants Inc. with an effective date of December 13, 2019, 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.
