Goldhaven Resources begins diamond drilling at Copecal

Executive Summary

• Goldhaven Resources has commenced its first diamond‑core drilling program at the Copecal gold project in Mato Grosso, Brazil.
• The initial hole (COP‑25‑001) has intersected ~30 m of saprolite over strongly sheared, hydrothermally altered basement gneiss with classic alteration minerals (chlorite, sericite, quartz), supporting the company’s exploration model.
• The program targets 1,200 m across five to six angled holes (up to 150 m depth) on east‑ and west‑zone targets; assay results are expected within 4–6 weeks.

Key Details

• Drill Hole COP‑25‑001: Reached planned depth of ~100 m; intersected ~30 m saprolite then entered altered gneiss.
• Alteration Suite: Chlorite, sericite and quartz – indicative of hydrothermal fluid activity linked to gold mineralization in orogenic/intrusion‑related systems.
• Drilling Contractor & Core Size: Ecodrill using NQ‑size diamond core (47.6 mm diameter).
• Program Scope: 1,200 m total planned drilling; five to six angled holes testing east and west zone targets; individual hole depths up to 150 m.
• Assay Timeline: Samples processed by ALS Global (preparation in Cuiabá, assays in Belo Horizonte); results anticipated within four to six weeks after completion of drilling.
• Target Definition – East Zone: Surface gold >100 ppb Au and arsenic anomaly over a 3‑km strike; structural controls identified via VLF electromagnetic and magnetic surveys.
• Geophysical Context: Target lies within the Juruena gold province, an area known for mesothermal shear‑related and intrusion‑related deposits (e.g., Tocantinzinho).
• Historical Work: AngloGold Ashanti conducted extensive exploration 2010‑2016, confirming gold‑arsenic anomalies and structural traps.
• Management Quote: “The start of our maiden drill program marks a transformational milestone… early geological observations validate our targeting model and align with mineralized systems across the Juruena gold province.” – Rob Birmingham, President & CEO.
