Vancouver-based GoldHaven Resources Corp. has reached a significant exploration milestone at its Copeçal Project in Brazil's Mato Grosso State. The company announced completion of its fifth diamond drill hole, designated CO-05, representing the first-ever test of the Western Target area following four previous holes at the Eastern Target.
Drilling Progress and Geological Findings
The recently completed hole CO-05 reached a total depth of 140 metres, successfully intersecting a substantial clay-rich saprolite horizon that extended from surface to approximately 60 metres downhole. This weathered zone translates to roughly 50 metres in vertical depth. Below this saprolite layer, drilling encountered competent bedrock consisting of strongly sheared basement gneiss and muscovite schist.
These lithological findings are particularly significant as they match the rock types encountered in previous drilling at the Eastern Target, providing compelling evidence of structural continuity across the entire project area. The hole was specifically positioned to evaluate coincident geochemical and geophysical anomalies interpreted as potential extensions of the mineralized structural corridor observed to the east.
Expanded Exploration Program Underway
GoldHaven's reconnaissance drilling campaign continues with three additional holes planned to systematically evaluate both the Eastern and Western Target areas. This phase of exploration is designed to test anomalous gold-in-soil patterns and coincident very-low-frequency (VLF) electromagnetic anomalies that were previously identified and reported in July 2025.
The ongoing program aims to refine the understanding of subsurface geology, alteration patterns, and structural controls on potential mineralization across the property. By integrating geological, structural, and geochemical data, the company's technical team expects to enhance targeting accuracy along both the East and West anomalies.
Assay Results Anticipated
Investors and stakeholders are awaiting analytical results with considerable interest. Assay results for holes CO-01 and CO-02, drilled earlier at the Eastern Target, are expected within the next two weeks. Results for holes CO-03 through CO-05 will be announced following receipt, validation, and thorough review by GoldHaven's technical team.
The company continues to advance its exploration program over the coming weeks, with assay results from the initial drill holes anticipated in the near term. These findings will be crucial for determining the next steps in GoldHaven's systematic evaluation of the Copeçal Project's mineral potential.
