Vancouver, BC - TheNewswire - February 14, 2023 - VR Resources Ltd. (TSXV:VRR) (FSE:5VR) (OTC:VRRCF), the "Company", or “VR”, is pleased to report on the first phase of the mineralogy and metallurgy study of the REE critical metal mineralization at its Hecla-Kilmer (“H-K”) project in northern Ontario.
Highlights
-
Scanning electron microprobe (SEM) confirms PMREO(2) minerals hosted in monazite and parisite, phosphate and fluorocarbonate minerals, respectively.
-
The REE mineralogy is consistent. It does not change through the 461 m vertical intersection of continuous mineralization starting at surface at Pike Zone, and it is the same 2.5 km away at the South Rim Zone.
-
Monazite has proven REE extraction, and it is the focus of new REE facilities in Canada.
Context for New Data
REE critical metal mineralization was discovered at Hecla-Kilmer in the first reconnaissance drill program completed by VR in 2020. The 21 holes completed to date are shown in Figure 1.
The new mineralogy data reported herein are from an electron microprobe (EMPA) equipped with an Energy Dispersive Spectrometer (EDS). The work was completed by Renaud Geological Consulting Ltd. (RGC) based in London, Ontario, who have extensive experience on REE deposits in Canada. The six samples submitted for this study were designed to span the 500 metres of vertical extent of REE mineralization at Pike Zone, and mineralization 2.5 km away at the South Rim Zone.
CEO Comment and Drill Core Photos
From VR’s CEO, Dr. Michael Gunning, “I simply cannot understate the significance of these results towards the advancement of this REE critical metal discovery at Hecla-Kilmer.
First, these new SEM results are entirely consistent with results we have obtained from all of the state-of-the-art technologies we have been able to utilize from the very beginning of our exploration to better understand the REE mineralization. Suffice it to say, the new data on monazite are not surprising:
-
QEMSCAN analyses in 2020 by SGS Canada, Lakefield, which determined the styles of mineralization and alteration, and confirmed the role of monazite and apatite, a phosphate mineral, for hosting PMREO: Figure 2
-
Whole-core XRF scanning on site in 2021 by GeologicAI of Calgary, which improved real-time decision making for drilling, and confirmed the correlation between TREO and P: Figure 3
-
Lithium-borate fusion to optimize REE detection in drill core geochemical samples: Figure 4;
-
Electron microprobeanalyses (EMPA-EDS) in 2023 by RGC in London and reported in this news release to confirm monazite and parisite as the host minerals for the individual Permanent Magnet REO’s, both in apatite veins and in carbonatite breccia cement: Figure 5, Figure 6
This mineralogy is important. Canada is plagued with REE discoveries made during the past 60 years that have never been developed because of the difficulty in extracting and recovering REEs contained in silicate and/or refractory minerals. REE beneficiation from the sulfate mineral monazite is proven however, so the two new REE processing facilities that have been recently built in Saskatoon and in Utah in order to bolster domestic raw material supply for the EV industry in North America are both designed around REE concentrates with monazite mineralogy. As such, it is a significant milestone for the Hecla-Kilmer project that the new EMPA-EDS data confirm that the Permanent Magnet REO minerals are hosted in monazite and parisite.
Finally, the importance of the high proportion of the four PMREOs in REE mineralization at Hecla-Kilmer is worth re-emphasizing. This ratio is important because of the high price of the PMREOs, such as neodymium and terbium, in response to the demand for permanent magnets in electric vehicles and wind turbines. For comparison, published resources for most Canadian LREE deposits in carbonatite typically contain between 12-15% PMREO of TREO, which is roughly 40% lower than the 19-22% proportion at H-K. The graphic below enforces what that means for the value potential of this discovery.
Next Steps Planned for the Hecla-Kilmer Project in 2023:
For Phase 2 of our beneficiation study of the REE mineralization at H-K, VR has completed the scoping for a full metallurgy and mineral extraction study using a bulk sample obtained from drill core spanning a broad intersection of REE mineralization starting at surface at the Pike Zone. This work is planned for the first half of 2023, utilizing the recognized REE expertise at SGS Canada laboratories in Lakefield, Ontario, and building upon our work with SGS for the past two years.
Follow-up drilling is planned for the spring of 2023. It will focus on supporting the afore-mentioned advanced-stage studies at the Pike Zone, in addition to completing additional exploration drill holes targeting other areas of known mineralization discovered to-date.
Overall, the path forward for this emerging discovery is strengthened by its location, just 23 km to the northwest of the provincial hydroelectric dam at Otter Rapids, with supporting and active Ontario Northern railroad and Highway 634 infrastructure.

Figure 1. Locations and key REE intersections for the 21 drill holes completed to date at Hecla-Kilmer, plotted on a contoured RTP magnetic base map with superimposed 3D iso-shells from the MVI inversion. The new SEM mineral data reported herein are from Hole 13 at the Pike Zone, and Hole 15 at the South Rim Zone.
Figure 2. Drill core photograph above QEMSCAN imagery and element data from SGS Lakefield Research below, from bedrock surface at the top of Drill Hole HK20-004, showing the relationship between REE minerals and apatite, a phosphate mineral. Calcite inclusions in the apatite vein matrix contain REE-bearing monazite ((Nd,Pr,Dy,Tb)PO4) and parisite, and occur near altered magnetite needles with reaction rims of pyrite–iron carbonate (LREE)–pyrochlore (Na,Ca)2Nb2O6(OH,F). See Figure 1 for Hole 004 location, at the same collar as Hole 13 with 361 m @ 1% TREO.
Figure 3. Whole-core XRF and SWIR scanning on-site at the exploration drill camp at Otter Rapids in 2021, using technology by GeologicAI, Calgary. The scanning improved real-time decision making for drilling using down-hole geochemical and mineralogical plots generated in the field, such as the graphic log shown on the right. The correlation between TREO and P2O5 evident in the REE mineralization at surface in Drill Hole 004 is consistent with the correlation evident in drill core geochemical data shown in Figure 4. This correlation is also consistent with the apatite-monazite phosphate mineralogy for the PMREOs at Hecla-Kilmer as identified by both QEMSCAN (Figure 2) and SEM (Figures 5 & 6).
Figure 4. Geochemical plot of P2O5 vs. PMREO (the permanent magnet REOs) based on a robust data set derived from approximately 4,600 samples from the first 17 drill holes completed at Hecla-Kilmer. The correlation coefficient is nearly 1:1, and it reinforces the same correlation evident in XRF data for Hole 004 as shown in Figure 3. This correlation is consistent with the apatite-monazite phosphate mineralogy for the PMREOs at Hecla-Kilmer as identified by both QEMSCAN (Figure 2) and the SEM (Figures 5 & 6).
Figure 5. Upper: photograph of drill core at 173m depth with 2.8% TREO in drill hole HK22-013 from the Pike Zone at Hecla-Kilmer. The pink and green areas are high temperature, potassic alteration which displays elongate, quenched magnetite and biotite crystals in a matrix of fluorapatite and carbonate. Lower: scanning electron microprobe image at 175m depth in HK22-013 of a zoned apatite crystal; the areas of blue, pink and red pixels are REE-bearing monazite inclusions with Nd, Pr, Tb and Dy. The monazite occurs both as inclusions within apatite in veins, and in the carbonatite vein breccia cement.
Figure 6. Backscatter electron microprobe image from 111m depth in Hole 15 at the South Rim Zone. The abundant areas of bright white reflectance are inclusions of REE-bearing monazite, parisite and britholite within larger, zoned crystals of apatite. This style of REE mineralization, with Nd, Pr, Tb and Dy contained in monazite and parisite as both inclusions within apatite and as isolated crystals in carbonatite breccia cement is consistent across Hecla-Kilmer, from the South Rim to the Pike Zone located 2.5 km to the north (Figure 5).
