Rush announces name change to Rush Rare Metals Corp., as well as new exploration work to commence in the spring on its rare earths property in Quebec

 In News

Vancouver, B.C. – March 16, 2023 – RUSH URANIUM CORP. (“Rush” or the “Company”) announces that it is changing its name to “Rush Rare Metals Corp.” The Canadian Securities Exchange will publish a bulletin announcing that the Company’s common shares will commence trading under the new name on or about March 21, 2023. The Company’s stock symbol of ‘RSH’ will not change. Shareholders are not required to exchange their existing share certificates for new certificates bearing the Company’s new name and Company shares held electronically in Direct Registration System will be booked automatically.

The Company still maintains its wholly-owned subsidiary, Rush Uranium Wyoming LLC, domiciled in Wyoming, which holds the Company’s interest in its Copper Mountain Property, comprised of 110 claims and which includes the historic Arrowhead Uranium Mine, a previously explored area known as the North Canning Deposit, as well as some other historically documented uranium occurrences.

The Company is also pleased to announce that it has secured the services of Resources Maxima Inc., a Quebec based exploration services company, to conduct further exploration activities at the Company’s Quebec rare earths property, known as the Boxi Property, as soon as there is reasonable weather access to the site in the spring.

Boxi Property Summary

The Boxi Property is comprised of over 2,500 hectares located about 70 km North of Mont Laurier, Quebec, in a district well known for rare earth and lithium prospects.

Previous work at Boxi has revealed an at least 8.5 km mineralized dyke, possibly as long as 14km, near surface, and which has visible white pegmatite and highly-elevated radiation levels. Minimal sampling along exposed mineralized sections of the dyke has provided very promising results – with only five cut samples having been taken and lab analyzed, and two of those samples returning niobium levels of 26.9% and 3.1%, respectively. It is noteworthy that the sample returning 26.9% niobium also contained 11.9% uranium.

Diagrams showing the claim location area, results from a 2021 spectrometer survey, as well as a picture of one of the exposed mineralized sections of the dyke are provided below:

Upcoming Work at Boxi

Depending on the local weather over the coming weeks, Rush expects new exploration work at Boxi to commence on or around May 15th.

Resources Maxima Inc., which also conducted earlier work at Boxi, plans to complete more detailed mapping and sampling all along the at-surface or near-surface mineralized dyke, which is expected to give us a better idea of the continuity and scale of mineralization throughout the 8.5 km (and potentially as long as 14km) occurrence. Moreover, additional prospecting will be done to investigate the possibility that other mineralized dykes, yet undetected, may be present. Finally, any samples taken from the identified system and/or new occurrences will also be analyzed for lithium, which was not one of the elements previously tested for.

It is expected that this preliminary work can be completed within 15-30 days once weather allows access to the area, at which point information obtained will be analyzed and used to devise a more detailed work program for the summer. This program will also be largely based on the recommendations within the NI 43-101 report completed for the Company, and as detailed in our recent prospectus dated December 13, 2022 and available on SEDAR.

Copper Mountain Summary

Through its Wyoming subsidiary, Rush Uranium Wyoming LLC, the Company holds 110 claims in what is known as the Copper Mountain area, near Riverton, Wyoming.

The Copper Mountain claims include the historic Arrowhead Uranium Mine, a previously explored area known as the North Canning Deposit, as well as some other historically documented uranium occurrences.

Rush has secured the services of BRS Engineering in Riverton, Wyoming, to complete an NI 43-101 report respecting the Copper Mountain Property, which we expect to be completed in March of 2023. We expect to provide more information about Copper Mountain, previous uranium mining and exploration within the claim area, as well as more detailed plans for Copper Mountain, in coming weeks.

Rush’s CEO, Pete Smith, commented generally about what’s coming for Rush over the coming exploration season: “We are very fortunate to have our flagship project, Boxi, in the mining friendly jurisdiction of Quebec, as well as in an area well-known for having great rare earth prospects. Although the exploration history at Boxi is limited, early results have been very promising. We appear to have a highly identifiable
and accessible system, near surface, which has returned very high levels of Niobium in two of the five samples taken. This is an outstanding start for us at Boxi, and further work is expected to further define this prospect efficiently, given that our initial area of interest is right at surface and has been well-identified by our 2021 spectrometer survey. It’s also tremendously exciting that none of the previous work focused on the potential for lithium at Boxi, given the presence of visible pegmatites and that there are other lithium projects in the area. At the same time, we have an enormous potential opportunity at Copper Mountain with uranium, with a claim area encompassing a past producing uranium mine and again, in one of the more favorable mining jurisdictions we could hope for in Wyoming. We look forward to having more to say about Copper Mountain once the upcoming NI 43-101 report is finalized.”
