Forward-Looking and Cautionary Statements
This presentation does not constitute an offering of securities and the information contained herein is subject to the information contained in the Company's continuous disclosure documents. All amounts expressed in
Canadian $ unless otherwise stipulated.
Forward-looking Statements
This presentation includes certain statements that constitute "forward-looking statements", and "forward-looking information" within the meaning of applicable securities laws (collectively, "forward-looking
statements"). All statements, other than statements of historical fact, are forward-looking statements. These statements appear in a number of places in this presentation and include statements made with respect to
anticipated exploration and development activities. When used in this presentation words such as "intends", "expects", "will be", "underway", "targeted", "planned", "objective", "expected", "potential", "continue",
"estimated", "would", "subject to" and similar expressions are intended to identify these forward-looking statements. Forward-looking statements in this presentation include, but are not limited to: the impacts and
benefits of the Warintza Project; future updates to the mineral resource estimates of the Warintza Project; the completion of resource drilling, a pre-feasibility study and permitting at the Warintza Project; the
submission of an Environmental Impact Assessment; the Company’s entrance into an exploitation agreement and expected permitting completion; the expected spin-out of Solaris Exploration; sales of electronic
vehicles; battery prices; and the supply and demand of copper.
Although Solaris Resources Inc. (the "Company") believes that the expectations reflected in such forward-looking statements are reasonable, undue reliance should not be placed on forward-looking statements since
the Company can give no assurance that such expectations will prove to be correct. These statements 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 risks related to the business of the Company; global outbreaks and contagious diseases (including COVID-19); business and economic
conditions in the mining industry generally; the supply and demand for labour and other project inputs; adverse claims made by local communities; changes in commodity prices; unanticipated exploration and
development challenges (including failure of equipment or processes to operate in accordance with specifications or expectations, cost escalation, unavailability of materials and equipment, government action or
delays in the receipt of government approvals, industrial disturbances or other job action, and unanticipated events related to health, safety and environmental matters); adverse weather conditions; political risk and
social unrest; changes in interest and currency exchange rates; and the risks, uncertainties and other factors identified in the Company's periodic filings with Canadian securities regulators.
These forward-looking statements were derived using numerous assumptions, including assumptions regarding general business and economic conditions the Company’s ability to develop and maintain relationships
with local communities (including the local Shuar Centres of Warints and Yawi); commodity prices; anticipated costs and expenditures; the Company’s ability to advance exploration efforts at Warintza and its other
projects; and the results of such exploration efforts. While the Company considers these assumptions to be reasonable based on information currently available, they may prove to be incorrect. Forward-looking
statements speak only as of the date those statements are made. Except as required by applicable law, we assume no obligation to update or to publicly announce the results of any change to any forward-looking
statement contained herein to reflect actual results, future events or developments, changes in assumptions or changes in other factors affecting the forward- looking statements. If we update any forward-looking
statements, no inference should be drawn that we will make additional updates with respect to other forward-looking statements. All forward-looking statements contained in this presentation are expressly qualified in
their entirety by this cautionary statement.
Technical Information
The technical information contained in this document related to the mineral resource estimate at Warintza was approved by, or based upon disclosure prepared by, Mario E. Rossi, FAusIMM,RM-SME, Principal
Geostatistician of Geosystems International Inc., a “Qualified Person” as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects (“43-101”). See the corresponding technical report entitled
"NI 43-101 Technical Report for the Warintza Project, Ecuador (Amended)" with an effective date of April 1, 2022 and available on SEDAR+ under the Company's profile at www.sedarplus.ca. The remaining technical
information contained in this document 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 NI 43-101. Jorge Fierro is a
Registered Professional Geologist through the SME (registered member #4279075).
Cautionary Note to U.S. Investors Concerning Estimates of Mineral Resources
The mineral resource estimates described in this presentation have been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. The terms
"mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in accordance with Canadian National Instrument 43 101— Standards of Disclosure for
Mineral Projects (“NI 43 101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) – CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as
amended. These definitions differ from the definitions in requirements under United States securities laws adopted by the United States Securities and Exchange Commission. Under Canadian rules, estimates of
inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is
economically or legally mineable. An “inferred mineral resource” is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling.
Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and
must not be converted to a mineral reserve. It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Investors are
cautioned not to assume that all or any part of mineral resources determined in accordance with NI 43-101 and CIM standards will qualify as, or be identical to, mineral resources estimated under the standards of the
SEC applicable to U.S. companies. Accordingly, information contained in this presentation may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure
requirements under the United States federal securities laws and the rules and regulations thereunder.

dozen major discoveries, including the largest copper
mine in the world, La Escondida, which produced
~$10B of copper last year.
Assembled our pipeline of grassroots exploration
projects targeting future discoveries; programs led by
his protégé, Jorge Fierro, VP, Exploration.
Co-defined porphyry copper deposit model in 1970.
Direct application led to first discoveries (exposed
deposits); evolved technique for second wave
discoveries (obscured deposits); final evolution
targets blind discoveries.

Notes:
1. Mineral Resources have an effective date of April 1, 2022.
2. The mineral resource estimates are reported in accordance with the CIM Definition Standards for Mineral Resources & Mineral Reserves.
3. Reasonable prospects for eventual economic extraction assume open-pit mining with conventional flotation processing and were tested
using NPV Scheduler pit optimization software with the following assumptions: metal prices of US$3.50/lb Cu, US$15.00/lb Mo, and
US$1,500/oz Au; operating costs of US$1.50/t + US$0.02/t per bench for mining, US$4.50/t milling, US$0.90/t G&A; recoveries of 90% Cu,
85% Mo, and 70% Au.
4. Cut-off grade of 0.3% CuEq. Resource includes grade capping and internal dilution. Grade was interpolated by ordinary kriging populating
a block model with block dimensions of 25m x 25m x 15m.
5. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
6. Copper equivalent assumes recoveries of 90% Cu, 85% Mo, and 70% Au based on preliminary metallurgical test work, and metal prices
of US$3.50/lb Cu, US$15.00/lb Mo, and US$1,500/oz Au. CuEq formula: CuEq (%) = Cu (%) + 4.0476 × Mo (%) + 0.487 × Au (g/t).
7. Qualified Person is Mario E. Rossi, FAusIMM,RM-SME, Principal Geostatistician of Geosystems International Inc.
8. All figures are rounded to reflect the relative accuracy of the estimate.

Citi: Cautious for 2H’23, Extremely Bullish Once Growth Fears Subside
Amount of capital it takes for speculative capital to offset a physical surplus
equal to 1% of consumption is only ~$2bn in copper,
compared to $27bn in oil
Source: Citi Research, Commodities Strategy, Copper Book 2023 Update –The Energy Transition Bull Trade, July 24, 2023
Copper spec volatility relative to market size is 10-15x oil!
Copper positioning – cyclical plus decarbonisation-related could see
copper rise to ~4 Mt in 2025, double their prior highs
Potential scale of increase in positioning would dwarf the physical market
balances and could easily see prices reach $12-15k/t during 2025

Record Size Structural Deficits Fast Approaching

2. S&P Global, The Future of Copper, July 2022
Projected deficit:
2030: 7.6 Mt¹
2035: 9.9 Mt²
New discoveries now would not reach
production until mid-2030s; lead times
for projects lengthening due to social
and regulatory risks
Peak copper supply in 2024 as top 10 global mega
mines (25% supply) begin terminal decline due to
grades, depletion, water, and other constraints
S&P estimates copper demand will
double to over 50 Mt by 2050

Rapid growth from copper-intensive energy transition applications
(power grid, renewables, EVs, charging network, batteries) on top
of steady 2.4% p.a. growth from traditional end uses
