Project Overview
Copeçal Property
GoldHaven Resources Corp. is advancing exploration at the Copeçal Gold Project, a promising early-stage gold asset located in the heart of Brazil’s renowned Juruena Mineral Province. Positioned within one of the country’s most historically productive gold belts, the Copeçal Project spans 3,681 hectares in the Alta Floresta region of Mato Grosso State—an area known for significant geological potential and well-developed infrastructure.
Strategic Location with Year-Round Access
Just 60 km from the regional hub of Alta Floresta, the Copeçal Project benefits from excellent infrastructure including road networks, nearby hydropower, and access to skilled labor. The property lies approximately 600 km north of Cuiabá, the state capital, and is accessible year-round via MT-325, a well-maintained all-weather road. The region is mining-friendly and has a strong agricultural and commercial base, ensuring reliable access to support services.
A Rich History of Exploration
Between 2010 and 2016, AngloGold Ashanti conducted extensive exploration work across the GolddHaven’s (GOH) Copeçal project and its surrounding tenements, investing in geochemical surveys, geophysics and drilling. This work led to the identification of multiple gold-bearing anomalies, setting the stage for further exploration.
Stream sediment and soil geochemistry surveys
Rock chip sampling
Mechanized auger and Air core drilling (49 auger holes and 6 Air core holes)
Induced polarization (IP) and magnetic orientation surveys
AngloGold's exploration confirmed that the GoldHaven’s project lies at the intersection of two major shear zones, characteristic of other significant gold deposits in the region. AngloGold’s findings revealed two primary soil anomalies—NE and SW—with gold values up to 334 ppb Au in auger drilling and robust structural controls consistent with mesothermal gold systems.

In 2022, Boa Gold aimed to test mineralization at depth, followed by a high-resolution 216 km drone magnetometry survey in 2023. These initiatives confirmed structural trends linking soil anomalies and enhanced understanding of subsurface geology.
Technical validation of AngloGold’s historical data, along with new geophysical interpretations, has strengthened the geological model. The integration of historic and modern data has highlighted the intersection of major shear zones—ideal conditions for structurally controlled gold deposition.
Situated in the Alta Floresta-Juruena-Tapajós gold corridor, the Copeçal Project lies within Paleoproterozoic magmatic arc rocks known for prolific gold mineralization. The project area exhibits:
High-grade soil anomalies
Ductile to brittle-ductile shear zones
Pinch-and-swell quartz lodes and mylonitic zones
Gold-arsenic-tourmaline geochemical signatures in stream sediments
These features are characteristic of known gold systems in the region, aligning Copeçal with nearby producing and historic mines.
Despite early-stage status, Copeçal exhibits strong potential. The scale and continuity of geochemical anomalies, aligned with confirmed structural corridors, suggest a significant mesothermal gold system at depth. Upcoming exploration programs include:
1
Auger Drilling Soil Program
Specialized drilling technique to excavate soil at depth.
2
Assay Analysis
Send samples from the auger program to the lab for geochemical analysis.
3
Airborne Geophysical Survey
Satellite or drone supported survey conducted over the property.
4
Diamond Drill Program
Conduct 1,000m maiden drill program.
With over USD $1 million in previous exploration investment the Copeçal Gold Project represents a compelling, underexplored opportunity in one of South America’s premier gold provinces.
The Company has completed 2,153m of Auger drilling over the East and West Targets. Over the East Target, drilling uses truck mounted motorized Augers (see figure 2) on a regular grid with holes spaced 50m and 100m apart along lines spaced at 200m intervals along strike. Over the West Target, 15 reconnaissance holes targeting geochemical and structural controls were completed.
A total of 1,325 samples, including QAQC samples, have been shipped to ALS Global Laboratories for analysis. Sample preparation is being undertaken at ALS’s facility in Cuiabá, Brazil, with final low detection fire assay analysis completed via their laboratory in Belo Horizonte, Brazil.
The Auger drilling for both the East and West targets as well as the magnetic VLF survey will allow for the preparation of a full 3D geometrical representation of the gold distribution in the regolith profiles from surface to bedrock and will be the guiding hand for delineation of drill targets.
