Solaris Reports First Drill Hole Intersection: 567m of 1.0% CuEq From Surface, Expands Warintza Central

Drill Results

(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.

Solaris Reports First Drill Hole Intersection: 567m of 1.0% CuEq From Surface,

Expands Warintza Central

August 10, 2020 – Vancouver, B.C. – Solaris Resources Inc . (TSXV: SLS) ("Solaris" or the "Company") is

pleased to report assay results for the first hole from the ongoing 40,000 metre (m) diamond drill program

at its Warintza Project (“Warintza” or “the Project”) in south-eastern Ecuador. This is the first drill program

made possible in nearly 20 years at Warintza and aims to expand the lateral footprint and depth extent

of the high-grade Warintza Central zone, discovered by the late David Lowell in 2000.

Highlights from the recent drilling are listed below and summarized in Table 1 and 2.

Highlights

 The first hole, SLS-01, returned a consistent, high grade interval starting from surface of

567m of 0.80% Cu, 0.04% Mo, and 0.1 g/t Au (1.00% CuEq) (1) and terminated in a barren dyke

(true width cannot be determined with the data and information currently available)

 SLS-01 greatly extends mineralization to depth and improves upon the grade of Warintza

Central in which historical drilling averaged less than 200m depth

 Geological interpretation places this interval in the ‘outer halo’ of the porphyry system, with the

higher-grade core to be vectored toward with additional drilling

 An advanced airborne geophysical survey commencing next week is expected to aid in targeting

at Warintza Central and within the broader 5km-long Warintza trend

 A secondary objective of the geophysical survey is to refine the series of three multi-km gold-in-

soil anomalies located northeast of Warintza and generated by soil sampling last year

 Additional drill results are expected by early September, with more frequent results expected as

drilling ramps up thereafter

Mr. Jorge Fierro, Vice President, Exploration, commented, “We are very pleased to have intersected a

long interval of consistent, high grade porphyry mineralization from surface on the first-ever deep hole

drilled on this property. The hole was collared within the footprint of Warintza Central, but greatly extends

mineralization to depth before terminating in a barren dyke. As expected, no significant values of

deleterious elements were detected in assaying.”

Mr. Daniel Earle, President & CEO, commented, “We are delighted to report the results of the first drill

hole completed on the Warintza Project in nearly 20 years, an achievement made possible through the

Strategic Alliance with the Warints and Yawi indigenous communities that forms the foundation of social

support for this project. With this result, we have begun to write a fitting epilogue to David Lowell’s

legendary career.”

(2) The Warintza Mineral Resource estimate was reported in the “Resource Estimate Of The Warintza Central Cu-Mo Porphyry Deposit" prepared

by Equity Exploration Consultants Ltd. with an effective date of December 13, 2019. The Warintza Central Mineral Resource statement has been

prepared by Trevor Rabb, PGeo who is a qualified person as defined by NI 43-101. The resource is reported using a cut-off of 0.2% copper. 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. Mineral Resources are not Mineral Reserves and do

not have demonstrated economic viability.

(3) 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.

Warintza Central is presently defined by a pit-optimized Mineral Resource estimate of 124 Million tonnes

of Inferred Resources grading 0.56% Cu, 0.03% Mo and 0.1 g/t Au (0.70% CuEq)(2), based on historic drilling

totaling less than 7,000m and averaging less than 200m in depth. The resource is entirely open laterally

and at depth and is set within the 5 km-long Warintza trend of porphyry mineralization. There has been

no drilling outside of the Warintza Central area.

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. ALS Labs is independent from Solaris. In addition, selected pulp check samples

are sent to Bureau Veritas lab in Lima, Peru. 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.
