Solaris Resources Inc. announced a preview of its 2024 plans for the company and its Warintza Project in southeastern Ecuador. Mineral Resource Update in second quarter/2024 ­ The company is nearing the completion of its second phase of mineral resource drilling at Warintza, which is expected to nearly double the meterage available for inclusion in the updated mineral resource estimate and deliver major growth through expansion of the deposit in extensional drilling at Warintza Central and Warintza East, and through the inclusion of the recent discovery of Warintza Southeast within a common pit shell. Extension and Infill Drilling: The third phase of drilling at Warintza is set to commence imminently and includes extensional drilling in areas in which the Warintza East and Warintza Southeast deposits are still open, and approximately 30km of infill drilling to further delineate and define mineral resources within the pit shell in advance of studies, with some of these holes doubling to provide technical data for mine design and mine planning purposes.

Warintza Exploration: Plans include following up on the recent Patrimonio discovery, where the first reconnaissance holes intercepted 144m of 0.50% CuEq¹ and 148m of 0.52% CuEq¹, respectively. Notably, these intercepts included skarn mineralization (in addition to porphyry) for which the source has not yet been located. Vectors for this mineralization trend northwest and are untested for over 1km toward Warintza West while the strongest soil geochemical anomalism is untested in the southern part of Patrimonio.

In addition, the company plans to revisit the El Trinche area that forms the southern, low grade margin of Warintza Central where a near surface intercept of high-grade mineralization within a broader low grade interval has been interpreted as a dyke with veinlet orientations and alteration suggesting it may form a high level expression of a potentially deeper, higher grade system that has not yet been located. Regional Exploration: Field investigation is planned to define drill targets at prospective areas identified in the regional exploration program to date, including: Medio Camino: a 3.5km x 1.5km porphyry target defined in soil geochemical data roughly equidistant between the Warintza porphyry cluster to the east and the neighboring San Carlos -Panantza porphyry cluster to the west; Clemente: a series of porphyry targets on trend to the north of the San Carlos - Panantza porphyry cluster; Mateo: a 3km x 1.4km area of copper-molybdenum enrichment in soil samples approximately 5km east of Warintza East that is expressed around the perimeter of an overlapping sandstone unit that may cover a porphyry; Caya: a 5km x 3km gold anomaly in stream sediments 6km northeast of Warintza East, where follow-up sampling has identified an area of 0.7km x 1.3km of anomalous gold, copper and epithermal pathfinder element values, and a concentration of dickite clay and vuggy silica alteration minerals characteristic of high sulphidation epithermal systems. Studies: Studies ­ The company anticipates finalizing and submitting the Environmental Impact Assessment for the Warintza Project for regulatory review and approval in second half/2024, after more than three years of baseline environmental monitoring, data collection and studies from prior permitting efforts. Follow-up programs for metallurgy, geotechnical and hydrogeological drilling, together with detailed access, internal/external infrastructure, and water and power studies will proceed under the direction of Javier Toro, recently appointed as Chief Operating Officer, and run through the end of the year.
