Rush Rare Metals Samples up to 6.9% Niobium and Expands Claim Area at Boxi Property in Quebec – Also Encounters Significant Uranium

Highlights:

  • Rush adds over 50 claims to cover additional areas where surface mineralization has been observed and provide further buffer around a large, mineralized dyke running east to west through the Boxi property at surface.
  • Photos of newly stripped portions of the dyke show dramatic visual evidence of intrusion and mineralization, potentially running for as far as 14km or more at surface through the Boxi property.
  • High niobium (Nb205) values have been found in new samples taken along the dyke, including as high as 6.9%, 2.32%, 1.56% 1.4% and 1.0% – these to be added to values of 26.92%, 3.09% and 2.41% previously returned from 2011 samples (also taken along the dyke).
  • High uranium (U308) values have also been found in new samples along the dyke, including as high as 3.46%, 1.33% and 7 other samples all over 0.1% – these to be added to values of 12.9% and 1.36% previously returned from 2011 samples (also taken along the dyke).

VANCOUVER, BC / ACCESSWIRE / October 16, 2023 / Rush Rare Metals Corp. (“Rush” or the “Company“) is pleased to announce that it has expanded the claim area at its Boxi property in Quebec (“Boxi” or the “Property”) 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 length of the Property. Figure 1, below, shows the new claims added. 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 (sample number 18 reported in Table 1 and Figure 3 below). 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, are included below.

Photograph 2 – Larger stripped and sampled area along pegmatite dyke immediately adjacent to 2011 sample.
Photograph 3 – Smaller stripped and sampled section farther along the dyke to the east.

In the 2023 exploration program, a total of 17 new samples were analyzed, with samples returning high niobium (Nb205) 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 engines, gas turbines, etc.)
  • as an additive with titanium or tin to create superconductive magnetic coils (which, in turn, are used in electronic vehicles, MRI scanners, particle accelerators, etc.)

There are currently only a very small number of niobium producers in the world. One of these, the highly successful Niobec Mine is only about 350km from the Boxi Property (in a straight line) and may provide an interesting off-take option for niobium-rich ore in the future.

Figure 2, showing the approximate location of the dyke and indicating the area where some stripping and sampling has occurred along it thus far is produced below.

Grades for uranium (U308) in many of the samples (both from 2011 and 2023) are also very interesting, including grades of 11.9%, 3.46%, 1.36%, 1.33%, and 7 other samples returning grades of 0.1% or higher. While there is currently a temporary moratorium on uranium mining and exploration in Quebec, and the Company is currently focused on the niobium potential at Boxi, it is certainly possible that Boxi could also hold strong uranium potential should the temporary moratorium ever be lifted. Note that the temporary moratorium was put in place in 2013, shortly following the Fukushima accident in Japan, and more recently some jurisdictions have considered a reversal of similar moratoriums (for example, Sweden lifted their ban on uranium mining in 2023 – https://www.mining.com/sweden-to-lift-ban-on-uranium-mining/).

Rush’s CEO, Peter Smith, said “We are very excited about these early results, and that they may be the start of confirming high levels of niobium occurrence right at surface throughout this pegmatite dyke for up to 14km or more across the Property.This, in addition to many other areas of high interest at Boxi, creates a highly encouraging scenario that demands further investigation. Further prospecting and investigation into key areas along the dyke, as well as the implementation of detailed geophysics, will help us to better understand just how large this system is. The fact that we are encountering such high grades right at surface makes the dyke enormously interesting from an economic perspective.”

Work at Boxi is ongoing. Additional areas along the dyke have already been fully exposed and sampled (with an additional 12 samples currently in lab for processing), and determinations surrounding the best geophysical approach to accurately measure the dyke’s size and depth are underway. We expect to be able to report on further developments in the coming weeks, and a more comprehensive geological report outlining all new work and its implications toward future work programs will be drafted as soon as is practical.
