Gold Hart Copper to Recommence Drilling at Tolita Gold-Copper-Molybdenum Asset in Vicuna District of Chile

Executive Summary

• Gold Hart Copper Corp. announced the commencement of Phase 3 drilling at its Tolita gold‑copper‑molybdenum project in Chile, using a Boart Longyear LF 90D diamond rig capable of up to 1,193 m depth.
• The company plans to drill ~700–900 m per month, targeting depths near 1,200 m – roughly double the depth achieved in its recent 600 m holes.
• Prior drilling (two 600 m diamond holes) intersected continuous porphyry‑style gold, copper and molybdenum mineralization; detailed intercept grades are disclosed.

Key Details

• Rig & Capacity: Boart Longyear LF 90D diamond drill rig secured; maximum rated depth = 1,193 m.
• Mobilisation Timeline: Rig to be mobilised within one week of release; drilling to restart a week after mobilisation.
• Planned Drilling Rate: Approximately 700–900 m of core per month.
• Historical Context:
• Late‑1990s RC drilling (≈200 m) intersected gold & copper in all three holes.
• Earlier 2025 diamond drilling achieved two ~600 m holes, both encountering porphyry‑style mineralization.
• Phase 3 Objective: Potentially double the 600 m depth to approach ~1,200 m, testing deeper extensions of the system.
• Geophysical Survey: Company may conduct an additional chargeability survey after drilling commences; focus remains on existing priority target east of fault (DDHTOL01).
• Key Intercepts from Prior Diamond Holes:
• DDHTOL02 – 203.5 m @ 0.25 g/t Au‑eq from 137.5 m (incl. 67 m @ 0.38 g/t); additional 118 m @ 0.24 g/t (incl. 45.5 m @ 0.30 g/t).
• DDHTOL05 – 10 m @ 0.62 g/t Au‑eq (highlight: 0.60 g/t Au, 0.34 % Cu, 20 g/t Mo → 0.97 g/t Au‑eq) within a 42 m intercept; below fault 22 m @ 0.40 g/t Au‑eq within 63 m mineralized zone.
• Assay Basis: Gold $3,340/oz, Copper $11,180/tonne, Molybdenum $61,917/tonne; equal recovery assumed.
• Funding: Drilling campaign is fully funded.

Notable Quotes

“We truly believe we've barely scratched the surface at Tolita relative to its potential… our rig can drill 4× deeper than historic RC holes and 2× deeper than recent diamond holes,” – Isaac B. Maresky, Co‑founder & CEO.
