GoldHaven Confirms Gold Mineralization in Bedrock at Copecal West Target, Including 39m of Mineralization in First-Ever Drilling
Executive Summary
- First-ever confirmation of in‑situ gold mineralization in unweathered granodiorite‑gneiss at the West Target (hole COPE‑PDH‑008), validating the company’s geological model.
- Significant intercepts include 39 m @ 0.11 g/t Au (including 3 m @ 0.30 g/t) in bedrock and high‑grade shoots up to 1.69 g/t Au over 1 m in saprolite.
- All four drill holes intersected gold above background, supporting the prospectivity of the Copeçal West Target and guiding follow‑up drilling plans.
Key Details
- Hole COPE‑PDH‑008 (Bedrock): 39.0 m @ 0.11 g/t Au from 58.0 m depth in fresh granodiorite‑gneiss; includes a 3.0 m interval at 0.30 g/t Au.
- Hole COPE‑PDH‑008 (Saprolite): 1.0 m @ 1.69 g/t Au near surface, indicating a high‑grade structural shoot to the surface.
- Hole COPE‑PDH‑006: 7.0 m @ 0.46 g/t Au from 21.0 m depth; best 1 m interval 1.21 g/t Au in sheeted quartz veins (gneiss, saprolite).
- Hole COPE‑PDH‑007: 28.0 m @ 0.14 g/t Au from 8.0 m depth; best 1 m interval 1.04 g/t Au in gneiss (saprolite).
- Hole COPE‑PDH‑005: 30.0 m @ 0.16 g/t Au from surface; best 1 m interval 0.20 g/t Au over 22 m in sheeted quartz veins (gneiss, saprolite).
All intervals reported as down‑hole lengths; true widths not yet known. Reporting cut‑off applied at 0.10 g/t Au with a minimum 1.0 m width.
Geological Highlights
* Sheeted quartz veining and structural deformation logged throughout fresh rock, consistent with intrusion‑related gold systems of the Juruena Province.
* Enhanced saprolite thickness (~60 m) at West Target suggests preferential weathering over altered/structurally impacted zones linked to underlying mineralization.
Next Steps
1. Physical property measurements (density, resistivity, chargeability) on core from all nine inaugural holes to calibrate IP/resistivity datasets.
2. Comprehensive multi‑element geochemical review and alteration characterization to refine structural model.
3. Structural analysis of foliation and shear zones in COPE‑PDH‑008 to define optimal drill azimuths for targeting sheeted vein shoots.
4. Integration of historic AngloGold Ashanti data (2010‑2016) with new core results to prioritize follow‑up drill corridors within the 6 km surface anomaly.
Notable Quotes
“These latest drill results represent a major milestone for the Copeçal Project… we have confirmed gold anomalism in fresh bedrock beneath the thick saprolite profile… we can now plan follow‑up drilling aimed at vectoring toward the core of what we believe could be a large and significant gold system.” – Rob Birmingham, CEO
“Hole PDH‑008 provides the first evidence that mineralization extends into underlying bedrock… this is a meaningful technical milestone that enhances our understanding of the mineralizing system.” – Jon Hill, Country Manager (Brazil)
