Solaris Resources Inc. announced the first significant precious metals assays from ongoing regional exploration that has expanded the footprint of epithermal-style mineral alteration from the Caya area into the adjacent Mateo target and now several kilometers further south. Reconnaissance rock-chip sampling in this new southern area returned values of up to 11,570 grams per tonne silver ("g/t Ag") and 12.3 grams per tonne gold ("g/t Au") across 30cm of breccia outcrop discovered as part of this program. Follow-up fieldwork is underway to refine targets for exploration drilling in late Third Quarter/24 or early Fourth Quarter/24.

Highlights: Ongoing regional exploration east of the Warintza cluster has expanded the area of interest for epithermal mineralization from the Caya-Mateo area several kilometres to the south; Epithermal deposits can be genetically related to porphyry systems and host rich concentrations of gold and silver, with this association well documented in southeastern Ecuador; The newly-sampled southern area is affected by minor fault splays off a major regional fault thought to be of Jurassic age, with kilometer-scale displacement across it; This fault separates intrusive-dominated geology to the west hosting the Warintza porphyry cluster from primarily volcanic-sedimentary geology to the east hosting epithermal mineralization; The footwall (western side) of this fault forms the margin of an adjacent north-south pull-apart basin filled with volcanic-sedimentary sequences; Initial reconnaissance rock-chip sampling in this area has returned values of up to 11,570 g/t Ag and 12.3 g/t Au across 30cm of breccia outcrop with exceptionally high concentrations of epithermal pathfinder elements; In addition to the above, sporadic high gold values of between 4 g/t and 9 g/t, with silver values up to 150 g/t, in rock chip sampling have also been returned, with anomalous pathfinder values consistently occurring over an area 1km by 2km; The working exploration concept is that these samples represent high-level expressions of an intermediate sulphidation epithermal system at depth; Detailed mapping and sampling of this area has commenced, with vectors from geochemical data and mineral alteration to be used to refine targets; Separately, recent sampling and spectral mapping in the Caya-Mateo target area have outlined pathfinder element and alteration anomalies at the margins of overlying sandstones; Mateo requires follow-up programs to extend coverage southeast over this large target area and establish metal and alteration zonation to define its core; A series of geotechnical holes previously planned in Caya-Mateo to support Pre-Feasibility technical studies near the epithermal target area, are expected to commence in July and are expected to provide valuable exploration data; Initial exploration drilling at Caya, Mateo and the new southern area will be planned on the basis of the ongoing exploration work and scheduled for late third quarter/2024 ? early fourth quarter/2024.
