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. 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 communities of Warints and Yawi); commodity prices; anticipated costs and expenditures; the Company’s ability to raise funding; 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 has been reviewed and approved by Jorge Fierro, M.Sc., DIC, PG, Vice President Exploration of Solaris who is a “Qualified Person” under NI 43-101. Unless
otherwise disclosed, all technical information related to Warintza is based on the “Resource Estimate of the Warintza Central Cu-Mo Porphyry Deposit" prepared by Equity Exploration Consultants Inc. with an effective
date of December 13, 2019. All technical information related to La Verde is based on the "Technical Report, La Verde Copper Project" prepared by AMC Mining Consultants (Canada) Ltd. with an effective date of June
20, 2018.
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.

Ecuador| Pro Mining Government
Support for Mining Sector Continues
Through Election
Guillermo Lasso elected President April 11th to
four-year term
Conservative, former banker, supports growth of
private sector, investment in natural resources,
targets oil production doubling and growth of
mineral exports
Recognizes importance of mining sector in growing
economy, employment, infrastructure, particularly
in under-developed regions
Mining accounted for $810M exports (4% of
country total), $430M in corporate taxes (22%),
$374M in foreign direct investment (46%) last year
Demands mining sector employ international best
practices, including community consultations, to
maximize local benefits and protect environment
Lasso committed to visiting Warintza Project and
has spoken in support of socially-inclusive and
environmentally responsible approaches to
development
Our objective is to boost Ecuador’s natural
resource sectors. In the oil sector, we have the opportunity
to double oil production in the medium term. We have minerals,
which we can also exploit under principles that respect nature
and the democratic will of the communities that host them.
Guillermo Lasso,
President of Ecuador
I want to make you a format invitation:
You are invited to make an official visit to the communities of
Warints and Yawi that are partners of Solaris in the Warintza
Project Strategic Alliance to see our model of development.
Vicente Tsakimp,
Indigenous Leader, Warintza Project Strategic Alliance
Once I am elected president of Ecuador, I will visit
your project in the Amazonia region.
Large investments, such as mining projects, boost small and
medium investments in Ecuador.
Guillermo Lasso,
President of Ecuador

Responsible Mining | Warintza, New Model for Mining in Ecuador
Warintza Success Story
World class discovery by David Lowell in 2000, sat
largely dormant since 2001 due to a breakdown in
social acceptance from local communities
Extensive dialogue led to understanding root causes
of conflict, resolution of underlying issues mid-2019;
instituted an informed, innovative CSR program
Government-Sponsored Prior Consultation process
and signed Memorandum of Understanding in 2019,
Impacts and Benefits Agreement in 2020
Warintza Model
Inclusive development model based on transparency,
dialogue, and trust relationship between government,
communities and company with the objective of
sustainable socio-economic development of
community and people together with project
Strategic Alliance governed by Board of Directors from
host Shuar Nations; community development alongside
project, with investments in health, education, training,
infrastructure, environment, entrepreneurship, gender
equality, labor, cultural and human rights and security
Ecuador is a megadiverse
country and we came to PDAC
to show the industry that it is
possible to develop mining
projects in a responsible and
inclusive way.
We are the main guarantee of the
Warintza Project.
Franklin Kuja
Indigenous Leader,
Shuar Nation Warints
The Shuar Nations of Warints and
Yawl have been working with
Solaris for more than three years
in the exploration and study of our
Ancestral Lands.
It has been a partnership, with two-way
learning and knowledge exchange.

Responsible Mining | Socially-Inclusive Approach
I want to acknowledge the efforts made by Solaris aimed
at responsible management. The extent of Its relationship
with the communities of Warints and Yawi has truly impressed
me as they strongly support the Project.
Solaris has carried out all activities in a socially and
environmentally responsible way, generating employment for
citizens respectful of labour rights and regulations. I would like to
highlight the transparent and multiparty actions taken to promote
health and education, and to solve some of the most critical
problems that the Shuar brothers in this area are faced with.

Goldman Sachs Forecasting Record High Prices
Cuts to exploration and early stage project development mean the size
and number of copper projects is substantially lower than a decade ago
Copper projected to trade up to $15,000/t by mid-decade
to mitigate depletion risks
Long-term supply gap implies significant
further upside to copper prices
Long-term copper price near $10,000/t is needed to incentivize to
enough approvals to mitigate the record LT gap

and early stage entry in early-stage
resources in Canada, Mexico and
Ecuador’
- BHP Group CEO, Mike Henry
‘Copper is our preference. A bit like BHP,
we’d love a Tier 1, large-scale and low-cost
asset. Ideally, shallow and near the coast,
with good infrastructure would be ideal’
