Oreterra Confirms Two Broad Zones of Epithermal Gold Mineralization with Assays to 50.5 g/t Au Overlying Porphyry Targets at the Kinkaid Project, Nevada

Executive Summary

• Oreterra Metals reports highly encouraging assay results from its 2025 field program on the 100 % owned Kinkaid project, highlighting multiple high‑grade gold and copper intercepts in both the Bismark Hill and PM Skarn zones.
• Grab and chip samples returned grades up to 50.5 g/t Au (sericite‑altered pod) and 4.8 % Cu, with additional widespread mineralization indicated by sericite anomalies, quartz‑vein pods, and epithermal style alteration.
• The company plans further detailed chip sampling, expanded soil and mapping work, airborne magnetic/radiometric surveys, and an induced‑polarization (IP) survey later in 2026 to advance targets toward drill‑ready status.

Key Details

• Project Overview: Kinkaid project located in the Walker Lane trend of southwestern Nevada; 100 % owned, road‑accessible.
• Bismark Hill Target – Assay Highlights
• Grab sample from a 20 m wide sericite‑altered zone: 50.5 g/t Au (red, hematite‑stained quartz‑vein pod).
• May 2025 comparable pod: 13.95 g/t Au.
• Chip samples across ~0.6 m and 1.52 m intervals: 23.68 g/t Au and 5.55 g/t Au, respectively.
• Large quartz veins (20–60 cm wide) up‑gradient of the sericite zone assayed 0.17–0.50 g/t Au and 0.20–0.55 % Cu; historic veins in the area have returned up to 36 g/t Au and 4.8 % Cu.

• Felsic volcanic rock with thin quartz±barite veinlets: 0.28 g/t Au over 9.45 m, with localized Sb (up to 25 ppm) and Cu (442 ppm).

• PM Skarn Zone – Assay Highlights

• Quartz‑flooded quartzite outcrop (50 cm wide): 1.36 g/t Au.
• Large chalcedonic boulder pieces (10–15 cm): 6.53 g/t Au and 2.16 g/t Au; a third piece without visible chalcopyrite: 80 ppb Au.
• Historical brecciated quartzite stockpile: 1.7 g/t Au (sample) and 3.2 g/t Au (April 2025 sample).

• Adjacent fractured quartzite chip sample (1.4 m): 0.33 g/t Au.

• Geochemical Indicators

• Elevated trace elements in sampled material: Hg up to 21,798 ppb, Sb up to 786 ppm, Mn up to 4,760 ppm, supporting an epithermal‑porphyry system model.

• Nearby silver‑rich stockpile (historical) assayed 1,725 g/t Ag (61 oz/t), 6.9 % Zn, 0.4 % Cu, 1 % Pb, and notable Hg/Sb levels.

• Planned Exploration Activities

• Detailed chip sampling of the two epithermal zones in spring 2026.
• Expanded soil sampling, mapping of additional sericite anomalies, and a property‑wide airborne magnetic & radiometric survey (2026).

• Follow‑up IP surveys to delineate drill targets after airborne work.

• Quality Assurance

• Samples processed by ISO/IEC 17025:2017 accredited Bureau Veritas labs in Reno, NV and Vancouver, BC.
• QA/QC program employed blanks and Certified Reference Materials every 10th sample; results within acceptable ranges.

Notable Quotes

“The Kinkaid property bears watching for its potential to deliver, within the next two years, a cluster of porphyry discoveries in one of the foremost mining jurisdictions in the world,” – Kevin Keough, CEO.

“The geology… (including up to 21,798 ppb Hg and 786 ppm Sb) is indicative of an epithermal mineralizing system, likely emanating from an intrusive, porphyry‑type centre at depth,” – John Biczok, P.Geo., VP Exploration.
