GoldHaven Resources (CSE: GOH | OTCQB: GHVNF | Frankfurt: 4QS) has provided an update on its ongoing exploration campaign at the 100%-owned Copeçal Project in Brazil, where the company continues to advance a 1,200-metre diamond drilling program aimed at testing key gold-in-soil and geophysical anomalies.

Rob Birmingham, CEO of GoldHaven Resources, commented in a press release: “We are very encouraged by the early geological observations from Copeçal. The alteration styles and structural features we’re seeing are consistent with a robust hydrothermal gold system. With drilling now underway at the West Anomaly, we’re testing a brand-new target area that has strong potential to deliver meaningful results for our shareholders. We look forward to providing assay updates as they become available.”

Four diamond drill holes totaling approximately 420 metres have been completed so far along a 200-metre strike length of the East Anomaly, one of several high-priority gold targets at the property. The company began drilling its fifth hole this week, which marks a significant milestone as it represents the first-ever test of the West Anomaly—a large gold-in-soil and auger anomaly that coincides with a strong very low frequency (VLF) conductive feature outlined in previous surveys.

Ongoing Drilling and Geological Observations

The drilling campaign has intersected a sequence of sheared quartz–sericite schists and gneissic basement rocks displaying strong hydrothermal alteration. These include zones of intense silicification and chlorite–sericite alteration. GoldHaven reports that intervals of geological interest, where structural deformation and alteration are most intense, have been observed over drilled thicknesses of approximately 10 to 15 metres (estimated true width). These zones are interpreted to represent structurally controlled corridors with potential for gold enrichment.

Sampling from the first two completed holes, CPDDH001 and CPDDH002, has been completed. Samples from CPDDH001 have been delivered to ALS Laboratory for analysis, while samples from CPDDH002 are being shipped to ALS’s sample preparation facility in Cuiabá, Brazil. Sampling of the next two holes, CPDDH003 and CPDDH004, is currently underway, and results will be released once available.

GoldHaven plans to continue advancing the drill program in the coming weeks, integrating geological, structural, and geochemical data to refine targeting along both the East and West anomalies. The company expects assay results from the initial drill holes in the near term.

Location and Geological Context

The Copeçal Gold Project lies within the Alta Floresta Gold Province, a historically productive area that has generated numerous gold discoveries since the late 1970s. GoldHaven’s tenements span approximately 3,681 hectares in a geologically favourable portion of Brazil’s Juruena Gold Province.

Also known as the Juruena Magmatic Arc, this orogenic belt is recognized as highly prospective for mesothermal shear-related and intrusion-related gold deposits. The province hosts several established deposits and active projects, including G-Mining’s Tocantinzinho deposit. The region also contains porphyry-style systems such as Serabi and Jaca, along with epithermal-style deposits like X1 and Aura. The coexistence of multiple deposit styles underscores the exploration potential across the Juruena Gold Province, and by extension, the Copeçal Project.

Historical and Regional Exploration

Prior to GoldHaven’s acquisition, the Copeçal property benefited from significant historical exploration by AngloGold Ashanti between 2010 and 2016. During that time, AngloGold conducted auger and air-core drilling, geophysical surveys, and geochemical sampling that identified multiple zones of anomalous gold mineralization. The company’s systematic work outlined soil grids and auger drilling areas that revealed consistent gold and arsenic anomalies—geochemical indicators of significant mineralizing systems.

In addition to this historical dataset, GoldHaven has carried out recent geochemical soil sampling, drone-mounted magnetometry surveys, and reinterpretation of earlier drilling data. Together, these efforts have delineated multiple gold-bearing structures and high-priority targets that guided the design of the ongoing drill program.

GoldHaven’s current focus remains on advancing its 1,200-metre diamond drilling campaign and refining its geological model of the Copeçal Project. Data integration from ongoing sampling, mapping, and geophysical interpretation is expected to inform future drill targeting. The company indicated that assay results from the first phase of drilling will be reported once received, potentially providing the first indication of subsurface gold mineralization continuity along the East and West anomalies.

Located in one of Brazil’s most historically productive gold belts, the Copeçal Project continues to draw interest for its combination of favourable geology, extensive historical data, and multiple untested targets. As drilling progresses, GoldHaven Resources aims to determine the scale and nature of mineralization within this underexplored section of the Juruena Gold Province.
