Almadex Provides Update on Three Newly Identified

High Sulphidation-Porphyry Cu-Au Prospects in the Western USA, and Confirms Filing of

Arbitration Request with Mexico

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

follow up its press release of April 16 th, 2024 with updates regarding three more of the fourteen prospects

it has staked since early 2023 in the U.S. These three prospects are located in central Nevada and

Colorado, USA, and are prospective for high sulphidation gold and porphyry copper -gold deposits. The

Company is planning initial work programs designed to rapidly provide the exploration dataset to evaluate

whether these targets merit drilling in the summer field season of 2024. The Company has only conducted

preliminary exploration mapping and sampling to date.

RR, Nevada

The RR Prospect covers an area of hydrothermal alteration developed in volcanic rocks adjacent to

carbonate rocks. Alteration mapping at RR has identified a large alteration zone interpreted to be a porphyry

lithocap extending 2.8 km NW-SE and by at least 1 km NE-SW. Mapping also defined a very strong surface

pyrophyllite footprint of 1 km (NW-SE) by 0.5 km (NE-SW). Preliminary rock sampling returned high values

for pathfinder trace elements typically associated with the lithocap alteration identified. The Company has

recently completed a soil sampling survey at the prospect for which analytical results are pending.

Pilot, Nevada

The Pilot prospect in central Nevada covers an ar ea of hydrothermal alteration developed in syn mineral

intrusive rocks and sedimentary country rock. Phyllic alteration has been mapped and is characterised by

white mica and pyrophyllite alteration. Recent field mapping has also identified several outcrops with

evidence of porphyry-style veining. This includes veining interpreted to represent early magnetite, A type,

syntaxial B veins and late stage D type quartz -sericite-pyrite veining. A large mapping, rock sampling and

grid-based soil sampling program is planned in order to define targets for drilling.

KT, Colorado

The KT Prospect located in Colorado covers an area of intense hydrothermal alteration developed in

volcanic rocks cropping out as windows through post mineral basaltic flows. Preliminary mapping has

identified silicification and quartz -alunite alteration over a roughly 3 by 3 km area. The Company plans

follow-up geologic and alteration mapping along with geochemical soil sampling to help direct any further

exploration programs.

J Duane Poliquin, Chairman of Almadex commented, “ We have acquired these projects by staking and it

surprising to continue to find such high quality targets available in the western USA.. We are fortunate to

have sufficient cash and internal resources to advance these prospects during the coming season, and are

optimistic that many of them will merit significant further work. We have a track record of discoveries under

lithocaps, and we feel the varied and exciting projects in our portfolio have the potential to add to that

record.”

About Lithocap Alteration Zones

Lithocaps are extensive areas of hydrothermally altered rocks that occur above or adjacent to intrusive

rocks and related porphyry deposits. The hydrothermal alteration forms when ascending high temperature

magmatic fluids are released from the source intrusion below and alter permeable and reactive rocks

occurring above. Lithocaps can be over 10 by 10 km in surface area and over 1 km thick. The alteration

mineral assemblages vary, usually with distance from the intrusive source. Often more neutral and higher

temperature stable alteration mineral assemblage s are seen at depth, closer to the source intrusion and

potential porphyry deposit. More acidic and lower temperature stable assemblages generally occur higher

and farther away. Mapping of alteration minerals and geochemical analysis using soil and rock samples

can map these changes in mineralogy. This mapping can then provide a vector towards potential underlying

porphyry systems. If large areas of lithocap alteration are well preserved, they can obscure deep unexposed

porphyries and other styles of mineralisation. If no mineralisation is present at surface, drilling based on

geochemical and alteration vectors and aided by geophysical data is the best way to explore for buried

deposits.

In follow -up to its press release of June 11, 2024, to Company confirms that that it has commenced

international arbitration proceedings against the United Mexican States (“Mexico”) under the

Comprehensive and Progressive Agreement for Trans-Pacific Partnership (“CPTPP”).

The Company’s international arbitration claim against Mexico will be prosecuted pursuant to the established

and enforceable legal framework of the International Centre for Settlement of Investment Disputes (“ICSID”)

and relates to the 2.0% NSR royalty held by the Company’ s subsidiary on the mineral concessions

underlying the Ixtaca project. Almadex alleges that Mexico has breached its obligations under the CPTPP

through actions which blocked the development of the Ixtaca project and ultimately retroactively terminated

the Ixtaca project mineral concessions, causing the loss of the Company’s investment in Mexico.

Almadex initiated the six -month consultation period required under the CPTPP on December 13, 2023.

Mexico agreed to hold one consultation meeting, which took place on May 30, 2024, but it did not result in

an amicable resolution of the Company’s investment disput e. The Company filed notice of its intention to

submit a claim to arbitration against Mexico under the CPTPP on March 14, 2024, triggering a 90-day notice

period prior to filing. With this notice period now over, the Company has filed its Request for Arbitration with

ICSID.

As part of the CPTPP requirements, although still at an early stage in the arbitration process, the Company

must submit an initial and preliminary estimate of damages claimed. As noted in the Company’s press

release of March 14, 2024, Almadex is pursuing this arbitration together with Almade n Minerals Ltd., on

behalf of themselves and their Mexican subsidiaries, and based on a preliminary estimate will be seeking

damages of no less than US$200 million, in the aggregate. Almadex would be entitled to damages relating

to its 2.0% NSR royalty on the Ixtaca project, if such damages were to be awarded.

As the arbitration proceeds, the Company expects to appoint a quantum expert who will prepare a

professional damages assessment for review by the arbitration tribunal. The Company will update

shareholders as this process evolves.

The Company has engaged international arbitration counsel at Boies Schiller Flexner to act on its behalf.
