About Quark uranium claims

The Quark uranium property consists of eight mineral claims totalling approximately 28,746 hectares (approximately 71,030 acres) located in the province of Saskatchewan, Canada, within the Athabasca basin region.

The property is situated within a well-established uranium-producing district in Northern Saskatchewan that has historically accounted for a significant portion of global uranium production. All of Canada's currently operating uranium mines and many of its known uranium deposits are located within the Western Wollaston domain and the Wollaston-Mudjatik transition zone. The Quark uranium property comprises a contiguous land position in this region and is in proximity to projects operated by established uranium exploration and mining companies, including Orano Canada and Fission Uranium Corp.

The properties are at an early stage of exploration and do not contain any known mineral resources or mineral reserves. While the company considers the property prospective based on its regional geological setting, there can be no assurance that further exploration will result in the discovery of economically recoverable mineralization.

Mineralization on adjacent or nearby properties is not necessarily indicative of mineralization on the Quark uranium property.
