Heraldo de Madrid - Rush Confirms Significant Expansion of Copper Mountain Uranium Project Claim Area and Provides Boxi Progress Update

The newly acquired areas include prospects generally known as Railroad, Steffen Hill, Cedar Ridge, Mole, West Mesa, and Lucky Cliff, plus extensions of existing areas such as Fuller, Mint, Midnight, and Knob (see Figure 1 below). Most of the new areas have confirmed significant surface or subsurface uranium mineralisation and may be prospective for other minerals. Some of the newly-acquired areas were previously targeted for uranium mineralisation in sandstone. This is important because sandstone-hosted deposits could be more amenable to in-situ recovery methods, if the conditions are favourable. All of the new areas were acquired by staking.

The expansion of the Copper Mountain Project claim area was largely guided by extensive information from historical exploration data (which includes over 2000 drill holes), mainly completed by Union Pacific during the 1970's, as well as insights from Myriad's 2024 successful maiden drill program.

Peter Smith, Rush's CEO, commented "We are very excited about the recent expansions at Copper Mountain, which adds a great deal of ground to our earn-in agreement with Myriad, creating exciting new value and potential for Rush shareholders. We have an ever-expanding collection of highly prospective zones at Copper Mountain which have all demonstrated great potential for extensive uranium mineralization through historical exploration records. In addition, Myriad's recent successful drill program in just one of these zones, at the Canning zone, has started to not only validate the historical work, but also increase our expectations in terms of the size, depth and grade in some of these mineralized zones. We anxiously await further exploration insights beyond the Canning zone, including for Mint, Bonanza, Fuller, Steffan Hill, Knob, Railroad, Midnight, Hesitation, Cedar Ridge, and others. It certainly appears that Copper Mountain is fast becoming Wyoming's largest and most exciting uranium project."

Boxi Property Update
The Boxi Property is a road accessible property comprised of over 8,000 hectares, located just a short distance from Mont Laurier, Quebec. Boxi was formerly held by Areva S.A. (now Orano), who held the Property based on early samples returning high values for uranium. Orano dropped the Property following the Fukushima incident in 2013, and uranium mining was subsequently suspended in Quebec under a temporary moratorium still in place today. Rush subsequently acquired the Property on the strength of niobium values in samples taken by Orano in 2011.

Niobium is categorized as a critical mineral in Canada and is used to make strong, light weight and corrosion resistant steel, superconductors, and various other highly topical products. There are only three niobium mines of any significance in the world, two of them in Brazil, and the third, the Niobec Mine, just 350km from Boxi in Quebec. Unlike these operating mines, which are hosted within carbonatite intrusions, the Boxi Property stands out by hosting niobium within pegmatite intrusions.

Previous exploration at the Boxi Property was summarized in a Company news release dated July 12, 2024.

We are pleased to report some more recent results from the Boxi Property. In the late fall of 2024, some additional channel samples were taken at various points along the mineralized dyke as shown below on Map 2.

Results from the channel samples are summarized on the following table:

The mineralized dyke at Boxi continues to be highly anomalous for niobium. However, recent results have failed to produce the much higher results often found in earlier prospecting programs. The niobium on the BX-1 showing is hosted in a pegmatite composed of quartz, feldspar, biotite and minor magnetite. The Boxi Property still holds significant untapped potential, particularly along the interpreted highly prospective NE-SW trending zone. This zone, spanning up to 15 km, has been delineated through interpretations from radiometric and magnetic surveys. The BX-1 Showing is located along that trend. Additionally, the presence of other critical-mineral-rich pegmatite occurrences in the area, as documented on the SIGEOM's government website, further underscores the strong exploration potential, both along strike and in other unexplored parts of the property.

In particular, a previously discovered radiometric anomaly at the far east of the Boxi Property along the NE-SW prospective trend should be further investigated. Additionally, the controls on pegmatite distribution and grade variability across the property remain to be fully understood.

Further analysis will be done over the rest of the winter and plans for future exploration work will be announced in due course, which may include geophysics, sub-surface investigation of the dyke and further stripping and sampling in other areas.
