SOLARIS COMPLETES SOCIALIZATION OF INITIAL DISTRICT EXPLORATION PROGRAMS

Solaris Resources Inc. has completed joint socialization programs with government entities and local communities to support the initial exploration activities of its district exploration programs at its Warintza project in southeastern Ecuador. The success of this socialization provides a template for broader ambitions in the northern Zamora belt for which the company intends to secure a joint venture partner.

Geotechnical drilling has now commenced in the Caya-Mateo target which is expected to provide important geological information to aid in more focused targeting efforts and subsequent discovery drilling. Meanwhile, fieldwork continues in the emerging Celestina epithermal gold/silver area where prior sampling returned values of up to 11,570 grams per tonne (g/t) silver and 12.3 g/t gold across 30 centimetres (cm) of breccia outcrop, with the next batch of results expected soon.

Socialization programs were attended by members of local communities, canton and provincial governments, and key ministries of the national government. The company presented its proposed initial exploration activities, including commitments for local hiring and contracting, undertaking education, technical training and capacity building, and community relations and environmental management programs.

Rene Cuesta, delegate of the Ministry of Energy and Mines, commented: "These types of meetings show us that it is possible to do mineral exploration in a united way: society, community, company and government. I congratulate the company and communities because communicating ratifies work in mutual harmony without discrepancies. This shows that the company works for the development of the communities and for the good of Limon Indanza canton, Morona Santiago province and Ecuador."

Cristian Leon, delegate of the Ministry of the Environment, commented: "We see that the process of socialization has been carried out with total transparency, complying with the previous processes of call and information. It is gratifying to see that the community, cantonal and provincial authorities all participated enthusiastically in this socialization. This is a demonstration of responsibility and commitment on all sides."

Jorge Valverde, political head of the Limon Indanza canton, commented: "Socialization with the communities is very important since all the work that will be carried out by the company is informed by their input. The communities have to understand what the processes are, the way of working and how the hiring will be carried out. I am representing the governor and I am very satisfied to see that people are accepting this information provided by the company."

Federico Velasquez, president, Latin America, of Solaris, commented: "Engaging with local communities ensures their concerns are central to our planning and enhances the benefits of our activities. Our exploration creates economic opportunities, supports local businesses, and advances community development. This approach aligns with community values, promotes sustainable growth and demonstrates our commitment to responsible mining."

Technical information and quality control and quality assurance

Sample assay, soil and rock 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 on site. Sample pulps are sent to ALS Labs in Lima, Peru, and Vancouver, Canada, for analysis. Total copper and silver contents are determined by four-acid digestion with AAS (atomic absorption spectrometry) 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. 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. The technical data have been verified by Jorge Fierro, MSc, DIC, PG, using data validation and quality assurance procedures under high industry standards.
