> Uranium exploration company listed on CSE: STMN, OTCQB: STMXF and FSE: Q7S. Approximately 41,577 hectares across four properties in two Canadian provinces: the Athabasca Basin, Saskatchewan, and North-Central Quebec.

## Company Overview

UraniumX Discovery Corp is a junior uranium exploration company operating in two Canadian jurisdictions: the Athabasca Basin in Saskatchewan, which hosts the world's highest-grade uranium deposits, and North-Central Quebec. The company holds four exploration-stage properties: Dieter Lake (~8,106 ha, 100% owned, Quebec), Murphy Lake (609 ha, earn-in up to 70%), Zoo Bay (19,850 ha, 100% owned) and NeoCore (13,012 ha, 100% owned).

On August 19, 2026 the company completed its acquisition of a 100% interest in the Dieter Lake uranium project from Consolidated Uranium Inc., a wholly owned subsidiary of IsoEnergy Ltd. (TSX: ISO) (NYSE American: ISOU), announced August 20, 2026. Consideration was 18,000,000 UraniumX common shares at a deemed price of $0.10 plus a 2.0% net smelter returns royalty; no cash was payable and no finder's fees were paid. Consolidated Uranium holds those 18,000,000 shares, approximately 15.2% of the issued and outstanding shares on a non-diluted basis, and IsoEnergy is a strategic shareholder of the company. IsoEnergy's shareholding is consideration for the sale of the Dieter Lake project; it is an equity investment and is not an endorsement of any UraniumX exploration result.

## Properties

### Dieter Lake - ~8,106 ha, North-Central Quebec (100% owned)
100% interest acquired from Consolidated Uranium Inc., a wholly owned subsidiary of IsoEnergy Ltd. (TSX: ISO) (NYSE American: ISOU). The acquisition closed effective August 19, 2026 and was announced August 20, 2026. Consideration: 18,000,000 UraniumX shares at a deemed price of $0.10 plus a 2.0% net smelter returns royalty to Consolidated Uranium; no cash was payable and no finder's fees were paid. Consolidated Uranium holds approximately 15.2% of UraniumX on a non-diluted basis, subject to a statutory four-month hold expiring December 20, 2026 and a voluntary lock-up releasing 25% every four months over 16 months. 168 mineral claims in a single contiguous block within the Gayot Lake basin. Stratabound pitchblende mineralization in the Sakami Formation traced over approximately 6 km of strike in four zones (Vivian, Nancy I and II, and Bert's), open to the southwest. The property hosts a historical estimate of 19.3 million tonnes at 0.057% U3O8 (approximately 24.4 million pounds U3O8), dated 2006. A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource, UraniumX is not treating it as current, and it should not be relied upon. UraniumX intends to compile and verify the historical drill database and to undertake confirmation drilling of selected historical holes. An updated NI 43-101 technical report is being prepared by Dahrouge Geological Consulting Ltd. No current mineral resources defined.

### Murphy Lake - 609 ha, NE Athabasca Basin

Key drill result: ML22-006 returned 0.242% U3O8 over 0.5m at 322.5m depth. MLEM ground geophysical survey completed May 2026; preliminary interpretation extended prospective conductor systems by 1.45 km. The F4-operated, UraniumX-funded 2026 drill program was completed July 7, 2026: nine holes totalling 4,092 metres across six target areas, defining the Murphy Lake North Trend (visible pitchblende in ML26-015) and the Murphy Lake South Trend, with anomalous radioactivity in five of six target areas. Radiometric readings are anomalous indicators, not assayed grade. Assays are pending. No mineral resources defined.

## Disclaimers

The Company has not defined any current mineral resources or mineral reserves on any of its properties. The Dieter Lake historical estimate is not a current mineral resource, is not being treated as a current mineral resource, and should not be relied upon. Mineral exploration is inherently speculative and involves significant risk. References to adjacent properties are for geological context only.
