Rush Rare Metals Corp. provided the following updates after completion of its spring 2024 exploration program at its Boxi property in Quebec and further updates respecting its Copper Mountain Property in Wyoming. Boxi is a road accessible property comprised of over 8,000 hectares a short distance from Mont Laurier.

Boxi was formerly held by Areva S.A. (now Orano), who held the Property based on early samples returning high values for Uranium. At Niobec, mining occurs at between 90 and 450 meters, and Niobium grades are between 0.4 and 0.5% (based on previous disclosures made by Niobec's operator). Given the limited number of Niobium mines world-wide, and the multiple and increasing uses for Niobium, there has been a surge of market interest in Niobium projects recently.

For example, on the strength of a new Niobium discovery in Australia, WA1 Resources Ltd. has climbed from a price of $0.14 per share in October 2022, to a current price of over $17 per share (and a market capitalization of approximately $1B AUD) as of July 11, 2024. The spring 2024 exploration program expands on a similar program conducted in 2023, both revolving around a mineralized dyke that runs along the surface through the Boxi Property and for a distance of as much as 15km or more. In addition to completing the spring 2024 program, some additional data was discovered on SIGEOM (a government sponsored interactive map containing geoscientific data collected within Quebec over the past 150 years) surrounding past exploration at Boxi - 15 additional samples taken along the dyke in 2011 that have not previously been reported.

Moreover, there are additional unexplored sections of the dyke which the Company plans to investigate, including a section in the Northeast area of the dyke which is identified as an anomalous zone on SIGEOM from a previously conducted airborne radiometric survey in 1969, and which happen to occur right along the projected path of the dyke. Copper Mountain Update: The Copper Mountain claim area is over 4,200 acres, located near Shoshoni in Wyoming, USA, and hosts several known Uranium deposits and historic Uranium mines, including the Arrowhead Mine which produced 500,000 lbs of eU3O8. Copper Mountain saw extensive drilling and development by Union Pacific, which developed a mine plan and built a leach pad for one of the deposits at Copper Mountain.

Operations ceased in 1980 before mining could commence due to falling Uranium prices. Approximately 2,000 boreholes have been drilled at Copper Mountain and the project area has significant exploration upside. Union Pacific is estimated to have spent CAD 117 million (2023 dollars) exploring and developing Copper Mountain.

On October 18, 2023, Rush signed a property option agreement with Myriad Uranium Corp. ("Myriad") pursuant to which Myriad has the option to earn up to a 75% interest in and to Rush's Copper Mountain Project, now covering over 4,000 acres near Riverton, Wyoming. Before Myriad earns a full 75%, here are requirements for Myriad to make expenditures on the property and to make share payments to Rush, and in addition Rush retains a favourable split on early production.
