Usha completes extension to Southern Arm survey

Executive Summary

• Usha Resources Ltd. has completed an extended ground induced polarization (IP) survey at its Southern Arm polymetallic volcanogenic massive sulphide (VMS) property in Quebec, aiming to refine drill targets and evaluate three high-potential zones.
• The 2025 survey extended the 2024 program, covering 40.33 line kilometres and integrating with previous data to provide comprehensive geophysical coverage of 9.7 square kilometres.
• The merged dataset identified nine polarizable trends, with six key targets prioritized for immediate follow-up, specifically highlighting high-priority targets IPSA-2 and IPSA-8 associated with the Bapst fault.

Key Details

• Survey Scope: The 2025 IP survey represents a southeastern extension of the 2024 program, designed to cover the full extent of the central northwest-southeast potential strike, including the Bapst fault, zinc zone, and southeast target areas.
• Survey Metrics: The survey encompassed 40.33 line kilometres at a 200-metre line spacing.
• Data Integration: The new data was integrated with 2024 results, providing comprehensive geophysical coverage totaling 9.7 square kilometres.
• Grid Framework: Established using two main baselines (BL 0 and 375N) intersected by three tie lines oriented at N128/N308, supporting 20 exploration profiles oriented at N38/N218, spaced at 200-metre intervals, with lengths ranging from 1.5 to 2.74 kilometres.
• Coordinate System: Georeferenced to UTM17N NAD83-CSRS using Garmin 60/76CSx hand-held receivers.
• Target Identification: The complete merged dataset outlined nine polarizable trends.
• High-Priority Targets (First to Third Priority):
  • IPSA-2 and IPSA-8: Located at Bapst West and Bapst East, these are structurally controlled anomalies directly associated with the Bapst fault.
  • Bapst Fault Significance: A 7.3-kilometre prospective strike length deformation zone suggesting significant opportunity for concentrated mineralization.
  • Historical Context: The Bapst fault hosts multiple peripheral mineralized zones with high-grade potential, including historical assays of 5.6 g/t Ag over 1.4 m and 1.9 g/t Au over 2.5 m.
  • Interpretation: Linear conductive targets adjacent to the Bapst fault are interpreted as exhalative horizons containing significant sulphide-graphite mineralization.
• Secondary Targets (Fourth to Fifth Priority):
  • IPSA-1, 4, 5, and 6: Located in the zinc zone and southeastern area, representing subordinate, lower-contrast induced polarization anomalies.
  • Geological Context: Locally correlated with resistivity fluctuations suggesting disseminated sulphide mineralization remobilized from the Bapst fault.
  • Historical Drilling: Encouraging zinc anomalism with selective intercepts yielding up to 0.4% Zn over 1.5-metre intervals.
• Lower Priority Targets:
  • IPSA-3, IPSA-7, and IPSA-9: Correlated with poorly contrasted geophysical anomalies and strong resistivity evidence.
  • IPSA-9 Specifics: Historical drilling in the vicinity returned low-grade results (up to 0.05% Zn over 1.2 m), suggesting limited economic significance.
• Property Overview:
  • Location: Southern Arm polymetallic VMS property in the metal-rich northwestern Abitibi subprovince of Quebec.
  • Size: 76 contiguous mining claims covering 4,218 hectares.
  • Geology: Dominated by volcanic rocks of the Brouillan-Fenelon group.
  • Nearby Operations: Hosts an approximately 7.3-kilometre conductive copper-gold trend along the regional-scale Bapst fault.
  • Regional Context: Located near the Selbaie mine (produced 56.5 Mt at 0.9% Cu, 1.9% Zn, 0.6 g/t Au, 38 g/t Ag) and the B26 deposit (13.0 Mt indicated at 2.1% CuEq).
