ATEX Provides Update on Resumption of

Operations at Valeriano

Toronto, Ontario--(Newsfile Corp. - April 20, 2026) -

ATEX Resources Inc. (TSXV: ATX) (OTCQB:

ATXRF)

("

ATEX

" or the "

Company

") provides an update, further to its news release dated April 15,

2026, regarding a contractor fatality connected to the Valeriano Copper-Gold Project in the Atacama

Region of Chile (the "

Project

").

The Company confirms that, following a review by the appropriate Chilean authorities, the temporary

suspension of activities at the Project were lifted on April 16, 2026. ATEX has since completed its

operational readiness review and will commence a phased return to work beginning on Monday, April

20, 2026.

The Company took additional time, prior to restarting activities, to allow employees and contractors to

support one another and their local community. ATEX appreciates the understanding and cooperation of

its workforce and community partners.

ATEX's highest priority remains the health, safety and well-being of its employees, contractors and the

communities in which it operates. The Company has maintained enhanced support and counselling

services for personnel and contractors and has reinforced critical risk controls across logistics and

drilling activities. Field activities will be reintroduced in a measured and coordinated manner. The

Company will provide further updates as appropriate.

As previously disclosed on April 15, 2026, the incident involved a contractor transporting road

maintenance materials approximately 32 kilometres from the Valeriano Project. Activities at the Project

were temporarily suspended in accordance with local regulatory requirements while authorities

commenced their review. The Company again extends its deepest condolences to the family, friends

and colleagues of the deceased and acknowledges the support and efforts of employees, contractors

and first responders during this difficult time.
