Goldhaven Advances Drilling at Copecal GOLD Project; East Anomaly Phase Completed
GOLDHAVEN ADVANCES DRILLING AT COPECAL GOLD PROJECT; EAST ANOMALY
PHASE COMPLETED
Vancouver, BC – October 29th, 2025 – GoldHaven Resources Corp. (CSE: GOH | OTCQB:
GHVNF | Frankfurt: 4QS) (“GoldHaven” or the “Company”) is pleased to provide an update
on ongoing exploration activities at its 100% -owned Copeçal Project in Brazil, where the
Company is advancing a 1,200-metre diamond drilling program designed to test key gold-in-
soil and geophysical anomalies.
Program Highlights
• Four diamond drill holes completed totaling ~420 metres at the East Anomaly
• Fifth hole collared, marking the first-ever drill test of the West Anomaly
• Strong structural deformation and hydrothermal alteration intersected in multiple
holes in the East
• Initial assay results expected shortly
To date, four diamond drill holes totaling approximately 420 metres have been completed
along a 200-metre strike length of the East Anomaly, one of several high-priority gold targets
at Copeçal. The fifth hole of the program was collared today, marking a key milestone for the
project as it represents the first-ever drill test of the West Anomaly—a large gold-in-soil and
auger anomaly spatially associated with a strong VLF conductive feature previously outlined
by the Company.

Drilling has intersected a sequence of sheared quartz –sericite schists and gneissic
basement rocks displaying strong hydrothermal alteration, including zones of intense
silicification and chlorite –sericite alteration. Intervals of geological interest, where
structural deformation and alteration intensity are most pronounced, were encountered
over drilled thicknesses of approximately 10 to 15 metres (estimated true width) and are
interpreted to represent structurally controlled zones with potential for gold enrichment.
Sampling from the first two holes has been completed: CPDDH001 samples have been
delivered to ALS Laboratory for analysis, and CPDDH002 samples are currently en route to
the ALS sample preparation facility in Cuiabá, Brazil. Sampling of holes CPDDH003 and
CPDDH004 is underway, with results to be released as they become available.

GoldHaven will continue advancing the program over the coming weeks, integrating
geological, structural, and geochemical data to refine targeting along both the East and
West anomalies. Assay results from the initial drill holes are expected in the near term.

Rob Birmingham, CEO of GoldHaven Resources, commented:
“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 mean ingful results for our shareholders. We look
forward to providing assay updates as they become available.”
About the Copeçal Gold Project: A Brief History
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 i dentified 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.
