Lodestar Confirms Significant Rare Earth Mineralization on the Virgin Mountain Property under Option from Globex
Executive Summary
- Globex Mining Enterprises Inc. reports assay results from five chip samples taken by Lodestar Minerals on the Virgin Mountain Rare Earth Property in Arizona.
- All samples returned significant total rare earth oxide (TREO) grades (1.00%–3.73%) with high concentrations of heavy rare earth oxides (HREO 48%–64%).
- Xenotime was confirmed as the dominant REE‑bearing mineral, indicating strong potential for critical HREEs such as dysprosium, terbium and lutetium.
Key Details
- Sample Assay Results (TREO / Contained HREO / Nd / Pr):
- CA050 – 3.73% TREO, 48% HREO, 17% Nd, ? Pr
- CA052 – 1.81% TREO, 58% HREO, 14% Nd, ? Pr
- CA049 – 1.67% TREO, 62% HREO, 13% Nd, ? Pr
- CA053 – 1.41% TREO, 64% HREO, 12% Nd, ? Pr
-
CA051 – 1.00% TREO, 50% HREO, 16% Nd, ? Pr
-
Analytical Methodology: Samples examined by Scanning Electron Microscope (SEM) with Energy‑Dispersive Spectroscopy (EDS) and Electron Backscatter Diffraction (EBSD) at the Centre for Advanced Microscopy, Australian National University.
-
Mineralogy: Xenotime identified as the dominant REE‑bearing mineral, confirming heavy rare earth potential.
-
Geological Context: Samples originate from a mineralized shear zone within a mapped 5 km‑long structural trend hosted by Paleoproterozoic gneiss.
-
Strategic Significance: HREEs (Dy, Tb, Lu) are classified by U.S. agencies as critically undersupplied and essential for EV motors, wind turbines, defense systems, radar, advanced military electronics, and nuclear reactors.
-
Future Plans (per Lodestar): Continued exploration and drilling to delineate the extent of xenotime‑bearing zones; further metallurgical testing to assess extractability of HREEs.
-
Reference Materials:
- Lodestar press release dated March 18 2026 (assay results & significance).
- Globex option agreement for Virgin Mountain Rare Earth property announced September 29 2025.
Notable Quotes
“The identification of xenotime is significant as it contains a high proportion of high‑value HREEs… all three of which have been repeatedly identified by agencies in the USA as critically undersupplied.” – Jack Stoch, P.Geo., Executive Chairman & CEO, Globex Mining Enterprises Inc.
Materiality Assessment: Material – Positive (the disclosed assay results indicate a high‑grade rare earth resource with strategic metals that could materially affect the company’s valuation and development plans).
