Globex of Canada Expands Gem Hills Rare Earth Mineral Rights in the United States to 20 Blocks and Completes Synchrotron Radiation Mineral Analysis

en.Wedoany.com Reported - On November 2, Canadian mining company Globex Mining Enterprises released the latest exploration results for the Gem Hills rare earth project in Nevada, United States. In October, the company expanded its contiguous mineral rights blocks from 8 to 20, covering a total area of 167.22 hectares, and received a mineral analysis report completed by the European Synchrotron Radiation Facility. The analysis results show that the project's rare earth mineralization is closely related to clay minerals formed by hydrothermal alteration, and the company has accordingly proposed a geological model suggesting the possible existence of a new type of hydrothermal ion-adsorption rare earth deposit.

The Gem Hills project is located on the eastern slope of the Clover Mountains in Lincoln County, Nevada, approximately 170 kilometers northeast of Las Vegas. After the addition of 12 new mineral rights blocks, all 20 mineral rights blocks of the project are located on public land managed by the U.S. Bureau of Land Management, with each block covering approximately 8.36 hectares. The company acquired the first 8 mineral rights in 2025 and completed this round of expansion in October 2026.

Of the 34 rock samples previously collected by Globex within the project area, 18 returned total rare earth oxide (TREO) grades ranging from 0.28% to 5.26%, with an average of approximately 1.7%. Heavy rare earth oxides accounted for an average of 8% of total rare earth oxides, reaching a maximum of 19%; dysprosium oxide grades reached a maximum of 0.09%, terbium oxide a maximum of 0.016%, and yttrium oxide a maximum of 0.435%. Neodymium and praseodymium oxides combined accounted for an average of 13.7% of total rare earth oxides, with a maximum combined grade of 1.14%.

This round of mineralogical study selected samples H-07, H-25, and H-29 from trenches E, C, and B, and conducted high-resolution synchrotron radiation X-ray diffraction analysis at the ID31 beamline of the European Synchrotron Radiation Facility (ESRF) in France. The TREO grades of the three samples were 1.889%, 2.281%, and 2.642%, corresponding to sampling lengths of 0.60 meters, 0.95 meters, and 1.75 meters, respectively. Globex received the final analysis report on October 19.

The analysis identified major minerals including nacrite, gibbsite, and nordstrandite, among which nacrite accounted for 26% to 46%, gibbsite for 0.25% to 10%, and nordstrandite for up to 17%. The detection proportion of the independent rare earth mineral bastnäsite was at most only 0.18%. The company therefore infers that more than 90% of the rare earth elements are mainly adsorbed in the aforementioned clay and aluminum hydroxide minerals, with a small amount possibly hosted in fluorite.

Preliminary geochemical testing shows that the project samples contain less than 20 ppm thorium and low uranium content. Globex plans to seek partners with financial and technical capabilities to advance subsequent systematic drilling and laboratory metallurgical testing; the company is also considering self-funding the next phase of work. The project has not yet completed a formal mineral resource estimate, and rare earth leaching recovery rates still require verification through metallurgical testing.
