Goldhaven Resources Corp. Advances Copeçal Gold Project with Initial Drilling and Plans Phase 2 Program At West Target
GoldHaven Resources Corp. provided an exploration update and outlined its forward exploration strategy following completion of the Company’s inaugural diamond drilling program at the Copeçal Gold Project in Mato Grosso State, Brazil. First-ever diamond drilling program completed at Copeçal, marking a major milestone in advancing the project from surface exploration toward subsurface discovery. Gold and copper anomalism intersected in drilling, accompanied by structural features and phyllic alteration consistent with a mineralized hydrothermal system. West Target emerges as the most promising zone, demonstrating widespread gold anomalism within both saprolite and underlying bedrock and forming the focus of planned Phase 2 drilling. Project supported by extensive historical exploration by AngloGold Ashanti, providing a strong technical foundation including geochemical, geophysical, and geological datasets now being integrated with new drilling results. Phase 2 drill program planned for mid-Second Quarter 2026, aimed at expanding mineralization and vectoring toward higher-grade zones at the West Target. The Company completed nine diamond drill holes during the inaugural drill campaign at Copeçal, representing the first-ever drilling program conducted on the property. The program tested two priority exploration areas referred to as the West Target and the East Target. Drilling successfully confirmed the presence of anomalous gold and copper mineralization, as well as structural deformation, quartz veining, and phyllic alteration consistent with hydrothermal mineralizing systems common to the region. These geological indicators support GoldHaven’s working model that the Copeçal Project may host a broader mineralized system and that the initial drilling campaign represents an important first step in vectoring toward higher-grade zones. The Company believes the results from this initial program provide valuable technical information that will significantly refine exploration targeting as the project advances to its next phase. Results from the West Target were the most encouraging from the program, with more consistent and widespread gold anomalism encountered in both saprolite and underlying bedrock. Drill holes targeting this area intersected a substantially thicker saprolite profile extending to approximately 60 metres downhole, which may reflect preferential weathering associated with structurally controlled alteration zones. Within the underlying granodiorite–gneiss host rocks, geological logging identified: Multiple phases of shearing and deformation; Quartz veining and sheeted veinlets; Structural fabrics consistent with potential fluid pathways; Alteration patterns typical of mineralized hydrothermal systems. These features collectively support the interpretation that the West Target may represent a larger mineralized corridor and will be the primary focus of the Company’s planned Phase 2 drill program. At the East Target, drilling intersected coincident gold and copper anomalism accompanied by phyllic alteration and structural features consistent with intrusion-related systems. While encouraging, the geological interpretation suggests that the initial drill holes may have intersected a more distal portion of the mineralized system, indicating that stronger mineralization may occur elsewhere within the broader target area. Further geological interpretation and targeting work is underway to evaluate follow-up exploration opportunities within this zone. GoldHaven has initiated a comprehensive technical review integrating the new drill data with historical exploration datasets generated by AngloGold Ashanti, including geochemical, structural, and geophysical data. This integrated interpretation will focus on refining the geological model and generating additional high-priority drill targets. Key components of the ongoing technical work include: Detailed multi-element geochemical interpretation; Structural analysis of mineralization controls observed in drill core; Alteration mineral characterization; Reinterpretation of historical geophysical datasets; Physical property testing of drill core including resistivity and conductivity measurements. These datasets will be used to refine drill targeting for a Phase 2 drilling program currently anticipated to commence by mid-Second Quarter 2026, with an initial focus on expanding mineralization and testing potential higher-grade zones at the West Target. The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil. The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project. Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization. The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.
