Roxmore Resources Reports Drill Results From Drill Program at the Converse Project, Battle Mountain - Eureka Trend Nevada

Executive Summary

• Roxmore reported a significant intercept in hole CV25‑007C: 194.5 m averaging 0.71 g/t Au from 190.2 m depth, including higher‑grade zones of 12.5 m at 1.14 g/t Au and 24.1 m at 1.77 g/t Au.
• The core results closely match historic reverse‑circulation (RC) drilling, extending mineralization an additional ~90 m below the RC hole and confirming a true thickness of roughly 150 m.
• Highest individual assay returned 5.39 g/t Au; overall data support continued confidence in the Converse resource model and underpin the upcoming Preliminary Economic Assessment (PEA) slated for Q2 2026.

Key Details

• Hole CV25‑007C – depth 385 m, azimuth 239°, dip ‑87°.
• Primary intercept: 194.5 m @ 0.71 g/t Au from 190.2 m depth.
• High‑grade sub‑intervals:
• 12.5 m @ 1.14 g/t Au (208.5 m)
• 24.1 m @ 1.77 g/t Au (281 m)
• Comparison to historic RC hole NK‑087:
• RC intersected 118.3 m @ 0.63 g/t Au (74.3 g·m).
• Twin core interval returned 104.6 m @ 0.73 g/t Au (76.3 g·m), confirming strong correlation between RC and core results.
• Extension of mineralization: Core hole extended ~89.6 m deeper than the historic RC hole, indicating potential for further resource expansion.
• True thickness estimate: Approximately 150 m based on bedding dip modelling and grade‑shell analysis.
• Peak assay: 5.39 g/t Au (fire assay with gravimetric finish).
• Geological context: Skarn‑related gold mineralization within the Havallah Formation; alteration trends suggest higher grades in retrograde zones.
• Metallurgical note: Gold recoverable by cyanidation across oxidized, transitional, and sulphide zones.
• Upcoming catalysts:
• Q1 2026 – additional drill results from current program.
• Q2 2026 – release of the Converse PEA.
