Dark Star Minerals Outlines Renewed Focus on Uranium Exploration in Stable

Canadian Jurisdictions and Announces Exploration Program and Share

Consolidation

VANCOUVER, BRITISH COLUMBIA, April 27, 2026: DARK STAR MINERALS INC. (CSE:

BATT) (the “Company” or “Dark Star ”) is pleased to announce a renewed strategic focus on

advancing uranium exploration assets located in stable, established mining jurisdictions, with

an emphasis on Canada’s premier uranium-bearing regions . This approach reflects the

Company’s commitment to operating in jurisdictions with established regulatory frameworks, clear

permitting processes, and a long history of responsible uranium exploration and development.

As part of this strategy, the Company has outlined a focused, phased exploration work program

designed to advance priority uranium targets at the Ghost Lake Uranium Project, with a planned

exploration budget of approximately C$300,000, subject to final program design and funding.

On April 15, 2026, the Company completed a Condition 2 (C2) extension of the Ghost Lake

mineral claims pursuant to the mineral tenure regulations of Newfoundland and Labrador,

maintaining the claims in good standing and allow ing continued exploration activities while

assessment work requirements are satisfied in accordance with provincial guidelines.

In addition, the Company confirms that it has extended its Bleasdell Lake uranium claims in

Saskatchewan, with tenure now secured through April  17, 2027, providing continued claim

validity while the Company evaluates and advances exploration plans on the property.

At Ghost Lake, the planned exploration program will emphasize surface ‑based geological

verification of previously identified radiometric anomalies and prospective lithological contacts.

Work will include detailed geological mapping and prospe cting across multiple priority target

areas, with particular attention paid to zones exhibiting elevated radiometric and gamma ‑ray

responses interpreted from historic datasets and more recent surveys. These areas are

interpreted to be associated with lithological contacts, structural features, and rhyolitic and

volcanoclastic units.

Field activities will incorporate hand-held scin tillometer surveys to refine the distribution and

intensity of radiometric responses on the ground. Where warranted, selective hand trenching may

be undertaken to improve bedrock exposure and evaluate subsurface continuity of anomalous

zones. Channel sampling will be conducted across trenched and naturally exposed bedrock to

support geochemical assessment and assist in defining priority follow-up targets.

The Ghost Lake program is designed to evaluate three principal target areas:

• The southwest portion of the property, where elevated radiometric responses are

associated with interpreted contacts and rhyolitic units;

• A north-central area, centered on the contact between volcanic and volcanoclastic rocks;

and

• A south-central area , where radiometric anomalies may represent extensions of

prospective lithologies identified elsewhere on the property.

Results from the planned exploration work will be used to refine geological interpretations,

prioritize targets, define drill targets and guide subsequent exploration activities.

Share Consolidation

The Company also intends to consolidate the common shares of the Company (each, a “Share”)

on the basis of ten (10) pre-consolidation Shares for one (1) post-consolidation Share

(the “Consolidation”).

The Consolidation will become effective at the opening of the market on May 1, 2026. The symbol

“BATT” will remain the same. The new CUSIP number will be 237234307 and its new ISIN number

will be CA2372343079 for the post-Consolidation Shares. Currently, a total of 91,468,102 Shares

are issued and outstanding. Accordingly, upon the Consolidation becoming effective, a total of

9,146,811 Shares, subject to adjustments for rounding, will be issued and outstanding. Where the

exchange results in a fractional share, the number of Shares will be rounded up to the nearest

whole Share. The exercise or conversion price and/or the number of Shares issuable with respect

to any of the Company's outstanding convertible securities will be proportionately adjusted in

connection with the Consolidation. There is no maximum number of authorized Shares.

Endeavor Trust Corporation (“Endeavor”) has confirmed that it will mail letters of transmittal to

those shareholders holding physical share certificates as of the record date of May 1, 2026

providing instructions on exchanging pre-Consolidation share certificates for post-Consolidation

share certificates. Shareholders are encouraged to send their share certificates, together with

their letter of transmittal, to Endeavor in accordance with the instructions in the letter of transmittal.

Endeavor has also confirmed that the registered shareholders as of the record date on May 1,

2026 who hold shares in DRS will be mailed a new DRS.

The board of directors is proceeding with the Consolidation on the basis that it may provide the

Company with increased flexibility to seek additional financing opportunities to further its

exploration activities. The Consolidation remains subject to the policies of the Canadian Securities

Exchange.
