Goldhaven Advances Drilling at Copecal GOLD Project; East Anomaly Phase Completed

Exploration Programs

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.
