Solaris Updates Technical Disclosure

VANCOUVER, Aug. 24, 2021 - Solaris Resources Inc. (TSX: SLS) (OTCQB: SLSSF) ("Solaris" or the "Company") announces that as a result of a review by the British Columbia Securities Commission, the Company recently became aware that Mr. Jorge Fierro, Solaris' Vice President, Exploration, was not able to act as a Qualified Person under NI 43-101 standards for select technical disclosure due to Mr. Fierro being an "SME member" and not the required "SME registered member".

Upon becoming aware of the above, Mr. Fierro began rectifying the matter and is in the process of obtaining the required registered member qualification, which is expected to be received shortly. In the interim, the Company's director, Mr. Donald Taylor, a Qualified Person under NI 43-101, has reviewed and approved the scientific and technical information in the Company's news releases and MD&As for which Mr. Fierro previously took responsibility, other than the Company's scientific and technical disclosure related to its La Verde project, which scientific and technical information was based upon the technical report titled "La Verde Copper Project" dated effective June 20, 2018, prepared by independent Qualified Persons Patrick Stephenson, Alan Riles, Mo Molavi, Michael O'Brien, and Phillipe Lebleu, and which has been superseded by the Company's most recent La Verde technical report (see the Company's news release dated July 23, 2021).

Mr. Fierro has over 22 years of exploration experience in South America, including 10 years in various positions with BHP Group, and is the protégé of the late David Lowell, who arguably made more discoveries of greater consequence than anyone in mining history.

The Company looks forward to Mr. Fierro resuming his role as the Company's Qualified Person.

On behalf of the Board of Solaris Resources Inc.
