Solaris Reports 154m of 0.90% CuEq, within 930m of 0.77% CuEq from Surface;
Increases Strike of Northeast Extension Zone by 200m
May 26, 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 holes aimed at upgrading and growing
mineral resources 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.
Northeast Extension
SLS-57 was collared at the northeastern limit of the Warintza Central grid and drilled northeast into an
entirely open volume, returning 230m of 0.73% CuEq¹ from 56m depth within a broader interval of 926m
of 0.61% CuEq¹ from surface, extending the zone 200m to the northeast where it remains open.
Additional drilling aimed at expanding the zone to the north from this platform and broadening the zone
with holes from the platform located 200m to the west where SLS-48 returned 100m of 1.64% CuEq² from
50m depth within 852m of 0.56% CuEq² have been completed with assays pending.
The Northeast Extension zone is characterized by near surface, high-grade mineralization, and represents
a priority target for growth of the ‘Indicative Starter Pit’ recently estimated at 180 Mt at 0.82% CuEq 1
(Indicated) and 107 Mt at 0.73% CuEq 1 (Inferred) within the Warintza Mineral Resource Estimate³
(“MRE”).
Warintza Central
A limited program of follow-up drilling at Warintza Central within the MRE envelope is aimed at
upgrading targeted volumes that the geological model predicts hold potential for higher grades than
the MRE reflects, as well as increasing the confidence of mineral resources in the Inferred category.
SLS-56 was collared from the southeastern portion of the grid and drilled east, returning 102m of 0.90%
CuEq¹ from 48m depth within a broader interval aimed at adding definition to the southern portion of the
overlap between the Warintza Central and Warintza East deposits.
SLS-60 was collared from the central portion of the grid and drilled south, returning 154m of 0.90% CuEq¹
from 70m depth within a broader interval of 829m of 0.58% CuEq¹ from 44m depth.
SLS-61 was collared from the south-central portion of the grid and drilled southwest, returning 930m of
0.77% CuEq¹ from surface, successfully infilling data in this area.
SLS-58 was collared from the south-central portion of the grid and drilled northeast into an area that the
exploration model predicted could be upgraded, and successfully returned 741m of 0.62% CuEq¹ from
102m depth, improving on the grade modelled in this volume.
SLS-59 was collared from the southwestern portion of the grid and drilled northeast, returning 238m of
0.85% CuEq¹ from near surface within a broader interval of 511m of 0.73% CuEq¹ from surface.
Suite 555 - 999 Canada Pl., Vancouver, BC Canada V6C 3E1
Mr. Jorge Fierro, Vice President, Exploration, commented: “Ongoing follow-up drilling from existing and
newly constructed platforms aims to expand on the Northeast Extension zone and grow the high-grade
indicative starter pit, while also targeting areas within Warintza Central where resource classification can
be upgraded with targeted drilling. In addition, we have completed a considerable amount of drilling from
our recent Warintza East discovery targeting major growth with assays pending.”

Endnotes
1. 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.
2. Refer to press release dated February 28, 2022. Copper-equivalence calculated as: CuEq (%) = Cu
(%) + 3.33 × Mo (%) + 0.73 × Au (g/t), utilizing metal prices of US$3.00/lb Cu, US$10.00/lb Mo, and
US$1,500/oz Au. No adjustments were made for recovery prior to the updated Warintza Mineral
Resource Estimate, as the metallurgical data to allow for estimation of recoveries was not yet
available. Solaris defined CuEq for reporting purposes only.
3. Refer to Solaris press release dated April 18, 2022, stating updated Warintza Mineral Resource
Estimate.
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
