Almadex Commences Drilling

at the King Copper-Gold Porphyry Exploration Target, Colorado

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

announce that it has commenced drilling on its King project in south -central Colorado. The King

project covers an area of intense porphyry lithocap and high sulphidation alteration developed in

volcanic rocks. This area has also seen historic mining for turquoise. In 2024 geologic and alteration

mapping was conducted as well as rock and soil sampling programs. The mapping identified

silicification and quartz-alunite alteration over a roughly 3 by 3 km area within which several str ong

Mo-Cu-Au anomalies were defined. The Company has since carried out induced polarisation (“IP”)

and magnetics geophysical surveys along with further mapping. The IP survey in particular helped

define drill targets and highlighted a large chargeability feature generally coincident with the area of

anomalous geochemistry. This first pass program will commence with an initial hole designed to

orient and allow better planning for possible additional drilling to be carried out.

J Duane Poliquin, Chairman of Almadex commented, “ We are very excited to have commenced

testing this new project in our portfolio which has gone from concept to first pass drilling in two

years.”

Technical Information and Qualified Persons

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

defined by National Instrument 43 -101 ("NI 43-101"), has reviewed and approved the scientific and

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 King drilling project and has reviewed and approved the contents of

this news release. The drilling program and core sampling will be carried out under his supervision.

The IP geophysical survey described was carried out using the Company’s in-house equipment, a 5

kW GDD transmitter and Iris Elrec -6 receivers. Pseudo sections were prepared and the data was

inverted using RES2DINV software. The magnetics survey was conducted by a third-party contractor

using a Geometrics MagArrow Cesium Magnetometer flown under an ArcSky X55 quadcopter. The

MagArrow sensor takes 1000 readings per second and is flown at a maximum speed of 8m/second.

The sensor is suspended on a 3m lanyard to remove it from the electromagnetic noise of the UAV .

Data is down sampled after collection to 10Hz. The MagArrow readings are diurnally corrected via a

geometrics G-862RBS Magnetometer, cycling at 10Hz. Geophysical surveys are not definitive, and

the results are still at an early stage of interpretation, with no guarantee of a mineral discovery.
