Rush Rare Metals Corp. announced that it has expanded the claim area at its Boxi property in Quebec to cover areas where additional pegmatites have been observed at surface and to create a further buffer around the mineralized pegmatite dyke that runs through the Property. The Property is now comprised of a total of 141 claims covering approximately 8,824 hectares.

The Company is also pleased to announce preliminary results from its work campaign over the summer. Resources Maxima, on behalf of Rush, has conducted extensive stripping and sampling in the area immediately adjacent to a high sample, returning 26.92% niobium (Nb205), which was taken in 2011. In addition, the dyke was followed and stripped and sampled in smaller sections approximately every 75m into the bush for nearly 1.5km along the dyke, running east from where the original 2011 sample was taken.

Two further samples were taken from an area about 4km west of the original 2011 sample. Photographs showing the original 2011 sample location, the larger stripped and sampled area immediately adjacent to it, as well as one of the smaller stripped and sampled locations to the east. In the 2023 exploration program, a total of 17 new samples were analyzed, with samples returning high niobium (Nb 205) values in 8 of those samples, those being 6.91%, 2.32%, 1.56% 1.4%, 1.0%, 0.96%, 0.74%, and 0.37%.

Three other samples of the 17 taken this past summer returned values over 1000 ppm. These are in addition to 3 of 5 samples taken in 2011 showing high Nb205, returning values of 26.92%, 3.1% and 2.4% respectively. All 22 samples were taken at or very near surface.

To put these numbers into perspective, economic cut off grades for underground niobium mining typically range from 0.2-0.5%, assuming it is found in sufficient quantities. Niobium is considered a critical element in many jurisdictions, and has multiple high-profile uses including: as an additive with iron to create corrosion resistant, high-strength and low-weight steel (then used to build pipelines, railway tracks, supports for bridges and buildings, etc.) as an additive with nickel-iron to create high-strength and heat resistant superalloys (and then used to build jet jet-to-tumum, which was taken in 2011.
