Gold
Diamond Drilling Underway At Goldhaven Resources Gold Property In Brazil
GoldHaven Resources And Brazil’s Golden Province
Brazil’s gold rush began in the 1690s in Minas Gerais, making it the world’s top producer by the 18th century. Modern exploration has increased output in the Amazon and Mato Grosso. Today, Brazil remains a key global gold producer with deep historic roots.
Gold was discovered in Brazil’s Mato Grosso in the 18th century, sparking a frontier rush that drew settlers deep into the interior. Modern mining and exploration has expanded the region. Today, Mato Grosso remains a key part of Brazil’s enduring gold story.

2021: ~16.0 t ≈ 514,412 oz

2023: ~20.0 t
(estimate; down from 2022 given national decline) ≈ 643,015 oz. — (ANM national data show an overall fall in 2023; I applied Mato Grosso’s recent share/range to estimate state output). Serviços e Informações do Brasil
2024: ~18.0 t
(estimate; includes formal mine output + a reduced but still-material informal component) ≈ 578,713 oz. — (company 2024 production from Mato Grosso mines is public — e.g., Ero and Aura — while national reports show artisanal (garimpo) recorded output fell in 2024; combined to give a conservative state total).

Highlights
Mato Grosso remains one of Brazil’s largest gold-producing states, accounting for a major share of national output.
Production peaked in 2022 (~23 t) before moderating in 2023–2024.
2024 totals include both industrial mining (Ero, Aura) and artisanal (garimpo) sources, adjusted for recent declines in informal output.
How To Participate in the New Gold Rush
Over the past decade, gold prices have steadily increased, recently reaching a high of $3,900 USD. This trend has resulted in notable returns for some investors. Historically, gold has shown strong long-term performance compared to other asset classes
GOLDHAVEN's tenements cover a total of 9,096 acres (3,681 hectares) in a geologically favourable setting within the Juruena gold province of Brazil.

The drill program will intersect primary bedrock with the targeted gold mineralization beneath the strongest geochemical anomalies. Results from the auger program and ongoing geophysics have significantly de-risked this phase.
Copeçal’s strategic location positions it among a growing cluster of significant gold discoveries and developments in the region. Projects such as G Mining’s multi-million-ounce Tocantinzinho deposit are now in development, while junior explorers including Altamira Gold, Cabral Gold, Keystone Mining, and Jangada Mines are making strides towards potential development decisions, supported by widespread mineralization and improving infrastructure.
The drill program is testing two key targets—Copeçal East and Copeçal West—identified through a combination of soil and auger drilling geochemistry, magnetic, very low frequency electromagnetic (VLF) and induced polarization (IP) surveys. These high-priority targets represent the culmination of systematic and rigorous exploration work carried out on a completely greenfields terrain.

Two large-scale soil anomalies (“East” and “West”), each with 3 km strike lengths, have been delineated. These anomalies align with a major regional scale shear zone, often a hallmark of the orogenic gold systems targeted by the company.
Auger drilling (107 holes), a VLF-EM geophysical survey and historical data generated by prior exploration phases (Boa Gold, AngloGold Ashanti) have confirmed structural controls and helped pinpoint diamond drill locations.
The Company has just completed 2,100 m of Auger drilling for the East and West Targets. This 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.

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 GOLDHAVEN project.

History
Between 2010 and 2016, AngloGold Ashanti conducted extensive exploration work across the GOLDHAVEN (GOH) 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.
AngloGold's exploration confirmed that the GOLDHAVEN project lies at the intersection of two major shear zones, characteristic of other significant gold deposits in the region.
All historical data completed over the Copeçal Project by AngloGold Ashanti, including soil and hand-auger geochemical sampling, drone Magnetic and trial Induced Polarization (IP) geophysical data has been compiled into a 3D project model which is being used by the GoldHaven Geological Team to plan the upcoming exploration phases.
Brazilian Management
Jonathan Victor Hill
Mr. Hill is GoldHaven’s Brazilian Country Manager and Founder & Principal Advisor of Exploration Outcomes Ltda. with +40 years’ experience, leading exploration, project development and mining operations globally. Mr. Hill holds a BSc (Hons) Economic Geology from University of Cape Town, South Africa and a BAppSc. Applied Geology from the Queensland University of Technology, Australia and is a Fellow of the Australian Institute of Mining and Metallurgy. He has been actively involved and/or directed several world-class gold and copper discoveries – greenfield and brownfield projects. Seasoned in governance, exploration strategy and management, he serves as a director on the boards of Royal Road Minerals (TSXV: RYR), Lavras Gold (TSXV: LGC), Avanti Gold (CSE: AGC), Spark Energy (CSE: SPRK) and was involved in Jaguar Mining (TSX: JAG), Sanatana Resources (TSXV: STA) and Australian Mines (ASX: AUZ).
Additionally, he held senior management roles at AngloGold Ashanti (“Anglo”) and spear-headed multi-million-dollar greenfield exploration projects in Brazil and Colombia including oversight of the exploration programs for Anglo on the Copeçal Gold Project now owned by GoldHaven.
During Mr. Hill’s tenure with Anglo between 2010 and 2016, Anglo conducted extensive exploration work across the Copeçal Gold Project and its surrounding tenements, investing in geochemical surveys, geophysics, and drilling.
