Solaris Resources Inc. reported an In-Pit Mineral Resources Estimate for its Warintza Project in southeastern Ecuador. Ongoing mineral resource drilling includes over 30,000m in H2/24 targeting open extensions and upgrading mineral resources to support the Pre-Feasibility Study in H2/25. In-Pit Mineral Resources - 232 million tonnes ("Mt") at 0.64% copper equivalent1 ("CuEq") (Measured) and 677 Mt at 0.49% CuEq1 (Indicated) for 909 Mt at 0.53% CuEq1 (Measured & Indicated) and an additional 1,426 Mt at 0.37% CuEq1 (Inferred) at a base case 0.25% CuEq1 cut-off grade; Includes 157 Mt at 0.76% CuEq1 (Measured) and 269 Mt at 0.69% CuEq1 (Indicated) for 427 Mt at 0.71% CuEq1 (measured & Indicated) and a additional 177 Mt at 0.62% CuEq1 (Inferred) at a higher cut-off grade of 0.50% CuEq1 which reflects the at or near surface supergene and higher-grade hypogene mineralization.

Structural Advantages - Warintza is set at low elevation within the southeast Ecuador mining district that is serviced by direct connection from highway to Pacific ports, low-cost hydroelectric grid power with further development potential at the adjoining Santiago G8 project, and has seen sweeping socioeconomic improvement from mining exploration, development over the last decade. Resource Drilling Continues - 2024 drill program of 60,000m (over 30,000m in H 2/24) in 140 holes from 80 platforms to provide improved drilling coverage targeting open lateral extensions, upgrading mineral resources and converting remaining unc categorized blocks within the pit shell to support the PFS in H2/25; metallurgical, geotechnical and hydrogeological drilling is ongoing, complementary district exploration efforts are targeting complementary discoveries from an expanded portfolio of epithermal gold/silver and porphyry copper targets, 2024 drill program of 60,000m (over 30.000m in H2/24) in 140 holes from 80 platform to provide improved drilling coverage targeting Open lateral extensions, upgrading mineral resources, upgrading mineral resources and converting remain unc categorized blocks within the Pit shell to support the PFS In H2/25; met allurgical, geotechnical, geotechnical and Hydrogeological drilling is ongoing, complementary district exploration efforts are ongoing, complementary district exploration efforts.
