The Warrants are subject to an accelerated expiry if, any time after the date that is 61 days following the Closing Date, the closing price of the common shares of the Company on the TSX Venture Exchange (“TSXV”), or such other market as the common shares may trade from time to time, is or exceeds $0.30 for ten (10) consecutive trading days, in which event the holders of the Warrants may, at the Company’s election, be given notice and the Company will issue a press release announcing that the Warrants will expire five (5) days following the date of such press release. The Warrants may be exercised by the holder of the Warrants during the 5-day period between the date of the press release announcing the accelerated expiry date and the expiration of the Warrants.

Net proceeds raised from the Offering will be used for the exploration of the Company’s Davidson River project and for working capital purposes.

In connection with closing of the Offering, the Company paid a finder’s fee of $54,000 and issued 540,000 non-transferable share purchase warrants (each, a “Finders’ Warrant”) to an arm’s-length party who assisted in introducing subscribers to the Offering.

About Standard Uranium (TSX-V: STND)

We find the fuel to power a clean energy future

Standard Uranium is a uranium exploration company and emerging project generator poised for discovery in the world’s richest uranium district. The Company holds interest in over 235,435 acres (95,277 hectares) in the world-class Athabasca Basin in Saskatchewan, Canada. Since its establishment, Standard Uranium has focused on the identification, acquisition, and exploration of Athabasca-style uranium targets with a view to discovery and future development.

Standard Uranium’s Davidson River Project, in the southwest part of the Athabasca Basin, Saskatchewan, comprises ten mineral claims over 30,737 hectares. Davidson River is highly prospective for basement-hosted uranium deposits due to its location along trend from recent high-grade uranium discoveries. However, owing to the large project size with multiple targets, it remains broadly under-tested by drilling. Recent intersections of wide, structurally deformed and strongly altered shear zones provide significant confidence in the exploration model and future success is expected.

Standard Uranium’s eastern Athabasca projects comprise over 43,185 hectares of prospective land holdings. The eastern basin projects are highly prospective for unconformity related and/or basement hosted uranium deposits based on historical uranium occurrences, recently identified geophysical anomalies, and location along trend from several high-grade uranium discoveries.

Standard Uranium’s Sun Dog project, in the northwest part of the Athabasca Basin, Saskatchewan, is comprised of nine mineral claims over 19,603 hectares. The Sun Dog project is highly prospective for basement and unconformity hosted uranium deposits yet remains largely untested by sufficient drilling despite its location proximal to uranium discoveries in the area.
