Ecuador's Mining Reset Is Opening Doors. Salazar Resources Is Walking Through All of Them

Ero Copper Corp. (ERO) released an exploration update on June 10, 2026, detailing progress at its Furnas Copper-Gold Project in Brazil. The company completed 24,000 meters of additional drilling, bringing the cumulative total to more than 75,000 meters. Assay results revealed significant step-out intercepts in the SE and Central zones, extending mineralization down-dip and along strike.

Key highlights include a 90m intercept grading 0.74% Cu and 0.50 g/t Au (1.13% CuEq), which extends the SE zone approximately 115m down-dip. Additional results included 45m @ 0.98% Cu, 0.36 g/t Au (1.25% CuEq) beyond the inferred resource limit, and a 41m intercept located 1.1 km west of the SE zone in the Central zone. Infill drilling in the SE and NW zones confirmed high-grade continuity, such as an 88m intercept grading 1.29% CuEq.

Ero Copper is meeting earn-in milestones two years ahead of schedule. A Pre-Feasibility Study is targeted for 2027, with engineering contracts expected to be awarded in mid-2026.

Ero Copper Corp. (ERO) released results confirming that the Furnas deposit remains large, high-grade, and expanding. This pattern of strong drill results has been recurring since Phase 1, with the Preliminary Economic Assessment (PEA) already capturing much of the expected scale. While these recent step-outs expand the deposit's footprint, they do not yet re-rate the resource or economics.

The stock price on June 10, 2026, was $35.91, only modestly above the prior session’s $36.50, and had declined from recent highs. This movement indicates the market had largely priced in the exploration success. Consequently, the news is positive but not material in the context of the previous PEA and resource delineation.

Ero Copper Corp. operates as a mid-tier copper-gold producer with assets located in Brazil. The company’s Caraíba Operations in the Curaçá Valley consist of an underground copper mine and mill, with production guided to reach 35,000‑40,000 t Cu in 2026 and rise toward 45,000‑50,000 t by 2028 following the completion of the Pilar shaft. The Tucumã Operation, an open-pit copper mine that began commercial production in July 2025, has 2026 guidance set at 32,500‑37,500 t Cu. Additionally, the Xavantina Operations feature an underground gold mine characterized by high-grade, narrow-vein deposits, with 2026 guidance for 40,000‑50,000 oz Au and the addition of gold concentrate sales from stockpiles. The company also holds a 60% earn-in interest in the Furnas Copper-Gold Project alongside Vale Base Metals, a large-scale, long-life porphyry-skarn deposit for which a 2026 PEA outlines a 24-year mine life and production of 108 kt CuEq/yr. All assets are situated in favorable Brazilian mining jurisdictions.
