Almadex Provides New Hope Drilling, Big Sky Project and General Exploration Update

VANCOUVER, B.C. Almadex Minerals Ltd. ("Almadex" or the "Company") (TSX-V: “DEX”) is pleased to

discuss the Company’s 2026 exploration program progress. Details are provided below.

Highlights

• Assays received from the initial hole of the New Hope porphyry copper-gold Project, Arizona,

first pass drilling program with phyllic alteration and high level veining encountered to 384

meters. Drilling complete on second hole;

• Magnetics and mapping suggest that the New Hope drilling to date is on the western edge of

a 2.5 km x 0.75 km area of mapped phyllic and remnant lithocap porphyry alteration;

• Surface sampling at the Big Sky epithermal gold -silver Project, New Mexico, returns further

significant results;

• Induced Polarisation (IP) Geophysical survey to commence at the Rattlesnake porphyry-

epithermal Project, Arizona;

• Drone magnetics completed at the New Hope, King and Rattlesnake Projects;

• Regional generative exploration program ongoing.

J Duane Poliquin, Chairman of Almadex commented, “ We are conducting a large and aggressive

early-stage generative exploration in the western USA. At the same time , we have begun first pass

drill testing of our new project portfolio. The results from the first ever Almadex drill hole on the

property confirm a large alteration system. We look forward to planning the next steps at New Hope

and a year focussed on generative exploration and advancing our exciting new portfolio of early-stage

porphyry and epithermal targets in the western USA.”

The Company has received further rock chip sampling results from the Big Sky epithermal gold-silver

Project, New Mexico, as discussed in more detail below. Drone based magnetic surveys have been

completed at the Company’s King, New Hope and Rattlesnake porphyry copper-gold prospects. The

data is being analysed and compiled with other datasets. An IP geophysical survey will commence

shortly at the Rattlesnake Project, Arizona.

New Hope Project Assay Results and Hole 1 Observations

The New Hope project covers a large (2.5 by 0.75 km) area of mapped phyllic and remnant

lithocap porphyry alteration. Recent drone-based magnetics suggest that the drilling to date

is on the western edge of the alteration zone and a broad magnetics low associated with this

alteration zone (see map attached). Assay results have been received from the first hole of

the current drill program at New Hope. Drilling of a second hole is now complete. The first

hole intersected andesite porphyry affected by moderate to strong phyllic alteration and

zones of quartz veining to 384 meters when, after a zone of faulting and brecciation, propylitic

to potassic alteration was encountered. Within the phyllic alteration, pyrite contents were up

to an estimated 7%. Quartz veining occurs largely as hairlines with pyrite, with some that

resemble the high level veining seen at surface above the hole, and others with banded

textures and fine pyrite. These latter veins are interpreted to be those typically seen in

shallowly emplaced porphyry systems , formed by the flashing of high temperature fluids

potentially above the level of copper mineralisation. The propylitic alteration encountered at

depth is associated with pyrite , magnetite and some pyrite -base metal veins with potassic

selvages. Anomalous gold was encountered in several short sections of veining within the

phyllic altered zone . While no significant copper mineralisation was encountered, the first

hole has confirmed a large porphyry alteration system is present. The second hole of the

program is complete and was drilled on the same section as the first (see attached map) .

Once assays are received and compiled from the second hole , next steps will be planned.

Further ind uced polarisation (“IP”) geophysics is planned in the near term to explore for

chargeability and resistivity responses to the east and northeast of the first two drillholes.

Big Sky Epithermal Gold-Silver Project, New Mexico

The Big Sky high sulphidation epithermal gold-silver project is located in western New Mexico

and covers an area of advanced argillic alteration and silicification hosted in rhyolite

volcanics and limestone. In 2025 Almadex announced (see Almadex release of April 9th, 2025)

the results from 57 grab rock samples taken from outcrop and subcrop ( grab samples are

selected samples and may not represent true underlying mineralisation) . These preliminary

results were very encouraging as 19 of these samples returned over 0.1 g/t gold with 4

returning more than 1 g/t gold (up to 3.5 g/t gold and averaging 0.26 g/t gold for all 57). The

better values were returned from zones of brecciation that are part of several parallel silicified

ridges that have been identified in the preliminary work. Soil sampling showed elevated gold

and epithermal suite elements in proximity to the gold in rock results. Together these results

helped define a broad area of prospectivity surrounding the outcrops mapped to date .

Further prospecting to the northeast was recently carried out and an additional 87 rock chip

samples from outcrop were taken returning up to 1.8 g/t gold and averaging 0.1 for all 87

(ranging from below detection to 1.8 g/t ). These new samples expand the area of potential,

and the Company is now planning to conduct further IP geophysical surveying to help define

drill targets.

The Company looks forward to reporting further results from this year’s work plan as it progresses

throughout 2026.

Qualified Persons

Morgan J Poliquin, PhD, PEng, the President and CEO of Almadex and a Qualified Person (“QP”) as

technical contents of this news release. Daniel Santamaria, P .Geo. and a Qualified Person as defined

by NI 43-101 is the QP for the New Hope drilling project, Arizona and the Big Sky project, New Mexico,

and has reviewed and approved the contents of this news release.

Blanks, field duplicates and certified standards were inserted into the sample stream as part of

Almaden’s quality assurance and control program. The grab samples reported in this news release

were taken from outcrop and subcrop. Grab samples are selected samples and may not represent

true underlying mineralisation. The analyses reported were carried out at ALS Chemex Laboratories

of Reno, Tucson and North Vancouver using industry standard analytical techniques. For gold ,

samples are first analysed by fire assay and atomic absorption spectroscopy (“AAS”). Samples that

return values greater than 10 g/t gold using this technique are then re analysed by fire assay but with

a gravimetric finish.

projects and NSR royalties in Canada, the U.S., and Mexico. This portfolio is the direct result of many

years of prospecting and deal-making by Almadex's management team. The Company owns several

portable diamond drill rigs, enabling it to conduct cost effective first pass exploration drilling in

house.
