Solaris Reports 105m of 0.60% CuEq and 132m of 0.60% CuEq from Near Surface;
Continued Expansion of Warintza East and Warintza Southeast
July 24, 2023 – 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 growing mineral resources
at the Warintza Project (“Warintza” or “the Project”) in southeastern Ecuador. Highlights are listed below,
with a corresponding image in Figure 1 and results in Tables 1-2.
Highlights
Warintza East was discovered in July 2021, with eight drill holes included in the Warintza Central Mineral
Resource Estimate (“MRE”)¹ in April 2022. Subsequent drilling has significantly expanded the dimensions
of the deposit, with drilling targeting further resource growth to the north, northeast, east and southwest.
● SLSE-27 was collared on the eastern limit of the Warintza East drill grid and drilled vertically to
the limit of the KD-200 rig, returning 132m of 0.60% CuEq² from near surface within a broader
interval of 246m of 0.55% CuEq², bottoming in mineralization and remaining open at depth
● SLSE-26 was collared 100m north of SLSE-27 and drilled vertically to the limit of the KD-200 rig,
returning 212m of 0.52% CuEq² within a broader interval of 310m of 0.45% CuEq² from surface,
ending in mineralization and remaining open at depth
● Step-out and deeper drilling is planned with two platforms under construction and a further six
scheduled to extend the drilling grid to the north, northeast, east, and southwest
Warintza Southeast was discovered in May 2023 as a distinct, higher-grade porphyry center to the south
of Warintza East beyond the limit of the MRE and offers potential to add higher-grade mineral resources,
with deeper drilling underway and significant step-outs to the southeast planned.
● These holes follow discovery hole SLSE-28, which returned an open-ended interval of 301m of
0.65% CuEq² in a favourable andesite porphyry host (see press release dated June 1, 2023), and
helps establish the geometry of the upper part of the system and vectors for further drilling
● SLSE-29 was collared east of SLSE-28 and drilled southeast to the limit of the KD-200 rig through
a less receptive intermineral diorite porphyry, returning 175m of 0.50% CuEq² within 289m of
0.40% CuEq² from near surface, with the final 105m averaging 0.60% CuEq² and open to depth
● SLSE-30 was collared west of discovery hole SLSE-28 and drilled southeast to the limit of the KD-
200 rig, returning 30m of 0.53% CuEq² from near surface within a broader interval of 275m of
0.48% CuEq², with the final 41m averaging 0.60% CuEq² and remaining open to depth
● Deeper drilling targeting extensions of higher-grade intervals noted at the end of each hole is
underway and two additional platforms are under construction for step-outs 250m and 500m
to the southeast where XRF³ values of 0.3% to 0.5% Cu in andesite porphyry were recorded

2. 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.

3. X-ray fluorescence ("XRF") is a non-destructive analytical technique used to determine the elemental
composition of materials such as drill core. XRF analyzers determine the chemistry of a sample by
measuring the fluorescent (or secondary) X-ray emitted from a sample when it is excited by a primary
X-ray source. It should be noted that the results only provide an indication of the amount of copper,
molybdenum and gold present. Certified assaying of the core samples is still required to accurately
determine the amount of base metal and precious metal mineralization.
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. XRF is a non-destructive analytical
technique used to determine the elemental composition of materials such as drill core. XRF analyzers
determine the chemistry of a sample by measuring the fluorescent (or secondary) X-ray emitted from a
sample when it is excited by a primary X-ray source. It should be noted that the results only provide an
indication of the amount of copper, molybdenum and gold present. Certified assaying of the core samples
is still required to accurately determine the amount of base metal and precious metal mineralization.

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,

Cautionary Notes and Forward-looking Statements
This document contains certain forward-looking information and forward-looking statements within the meaning of
applicable securities legislation (collectively “forward-looking statements”). The use of the words “will” and
“expected” and similar expressions are intended to identify forward-looking statements. These statements include
statements that subsequent drilling at Warintza East has significantly expanded the dimensions of the deposit, with
drilling targeting further resource growth to the north, northeast, east and southwest where step-out and deeper
drilling is planned with two platforms under construction and a further six in the works to extend the drilling grid to
the north, northeast, east, and southwest, Warintza Southeast offers potential to add higher-grade mineral resources
with deeper drilling targeting extensions of higher-grade intervals noted at the end of each hole is underway and two
additional platforms are under construction for step-outs 250m and 500m to the southeast where XRF values of 0.3%
to 0.5% Cu in andesite porphyry were recorded. Although Solaris believes that the expectations reflected in such
forward-looking statements and/or information are reasonable, readers are cautioned that actual results may vary
from the forward-looking statements. These statements are based on a variety of assumptions including assumptions
made about the Company’s ability to advance exploration efforts at the Warintza Project; the results of such
exploration efforts; and the Company’s ability to achieve its growth objectives. These statements also involve known
and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from
those anticipated in such forward-looking statements, including the risks, uncertainties and other factors identified
in the Solaris Management’s Discussion and Analysis, for the year ended December 31, 2022 available at
www.sedar.com. Furthermore, the forward-looking statements contained in this news release are made as at the
date of this news release and Solaris does not undertake any obligation to publicly update or revise any of these
