VR discovers Lithium – REE mineralization at Hecla-Kilmer copper-gold project in northern Ontario, stakes new properties and commences gravity survey
VANCOUVER, British Columbia, March 11, 2021 (GLOBE NEWSWIRE) -- VR Resources Ltd. (TSX.V: VRR, FSE: 5VR; OTCQB: VRRCF), the "Company", or “VR”, is pleased to provide an update on compiled and integrated geochemical data from the recent four-hole reconnaissance drill program completed late in 2020 at its Hecla-Kilmer carbonatite property and copper-gold breccia target in northern Ontario (“H-K”). Results include:
- A broad intersection of lithium mineralization discovered in drill hole HK20-002;
- Broad intersections of critical minerals, niobium-thorium-REE (rare earth elements), discovered in drill holes HK20-002 and 004, with corresponding high density profiles confirmed in XRF scanning;
- Detailed ground-based gravity survey is now underway to identify potential high density anomalies related to either copper-sulfide mineralization, and/or niobium-REE concentrations (Figure 1).
Context
As described in the previous news release dated December 17th, 2020, fluorite-rich hydrothermal breccia and iron sulfides were intersected within a high temperature, potassic alteration system which comes to surface and has more than 600 m of continuous vertical extent in two drill holes, HK20-002 and 004. The Company has now received, integrated and interpreted all geochemical assay data and XRF mineral scanning data obtained from the four holes totalling 1,971 metres completed last fall.
Key Results
- Chalcopyrite mineralization is confirmed in veinlets and scattered semi-solid sulfide replacement zones within hydrothermal breccia, with 1m assays of up to
0.12% (1240 ppm) (Photo 1). It occurs with hematite, magnetite, pyrite and apatite in zones of intense fenitization (potassic alteration) around and within phonolite dykes which are themselves elevated in gold, with 15-184 ppb gold over several + 40 metre intervals in drill hole HK20-002. A high density profile of 3.46 g/cm3 is confirmed by XRF specific gravity scanning across the zone of copper mineralization.
Complete geochemical and XRF (X-ray diffraction) analytical datasets demonstrate two significant new aspects to the mineral system at H-K:
- Intersections of critical mineral and REE mineralization span 49 metres starting at 50 m depth in HK20-004 and more than 20 metres at 574m depth in HK20-002 (Figure 2). They contain:
- Up to 0.56 % combined La2O3, Ce2O3, and Y2O3 ;
- Elevated thorium up to 0.15 % ThO2 ;
- Anomalous niobium up to 0.13 % Nb2O5 ;
- As much as 33.7 ppm terbium, a heavy REE.
The mineralization occurs in red-hued hydrothermal breccia with digested clasts of sovite dykes (Photo 3) and intense potassic alteration overprint (Photo 4). The two intersections have anomalous specific gravity profiles of 3.12 g/cc and 3.21 g/cc respectively, and their correlation across two drill holes some 200 m apart implies that the critical metal and REE mineralizing system at H-K has a vertical extent of more than 600 metres (see graphic logs in Figure 2).
- Lithium mineralization occurs in a broad interval of fluorite-carbonate hydrothermal breccia with 0.045 % LiO2 over 19.4 metres in drill hole HK20-002 (Figure 3). Light blue-gray alteration hues in the breccia is attributed to minerals such as spodumene. Fragmented and partially digested sovite-carbonatite dykes are common in these breccia zones (Photo 2). Heavy REE’s such as terbium are also anomalous in this zone alongside the HREE indicator yttrium.
The high density profiles of the niobium – REE mineralization correlate with high phosophate and are therefor attributed to minerals such as pyrochlore, monazite and potentially allanite. Such minerals are favourable for REE recovery and are common within the niobium deposits at Oka in Quebec and Argor in northern Ontario, but they are also present in association with copper-gold mineralization in IOCG deposits such as Palabora in South Africa and Olympic Dam in Australia.
Follow Up
A detailed ground-based gravity survey is now underway. It covers a roughly 3.5 x 1.5 km area over all of the magnetic and EM targets previously outlined, and is focussed on the margins of the syenite intrusion that cores the polyphase carbonatite complex at H-K (Figure 1). The survey will include between 600 to 700 stations on an equant 100m grid, and is anticipated to take two weeks to complete. The company will complete 3D inversion processing and modeling of the data upon completion of the field survey. The goal of the gravity survey is to identify high density copper sulfide or niobium – thorium - REE zones within the iron-sulfide bearing, fluorite hydrothermal breccia system and dyke swarm at H-K.
Immediate Action
The Company has staked two additional properties totalling 89 claims based on the newly recognized strategic metal mineralization evident in the integrated data sets from the drill program last fall. The properties are approximately 15 km to the northeast and 5 km southeast of H-K, respectively. The targets are derived from a regional GIS workspace compiled and refined by VR during the past two years, since starting on the Ranoke copper-gold generative project in 2018.
Comment
From VR’s CEO Dr. Michael Gunning “Our goal at Hecla-Kilmer is to pursue the discovery potential for a new, large-scale copper-gold hydrothermal breccia mineral deposit in Canada. But the point of this news release is to confirm that the potential for discovery of a copper-gold breccia deposit at H-K is now expanded to include the discovery potential of strategic rare earth elements (REE’s) and critical battery metals such as lithium. Importantly, the La, Ce, Y and P signature now evident in our fully integrated geochemical data sets confirm the IOCG-affinity of the hydrothermal breccia system at H-K.
The strong correlation between density and critical metal mineralization that we can also now see in our integrated XRF and geochemical assay data sets reinforces our conviction for the ability of the current ground gravity survey to improve our targeting for the follow-up drilling that is planned for H-K based on these new results from the maiden drill program last fall.”
H-K has scale, both the overall complex itself, and the hydrothermal breccia system discovered within it, and it is that scale which I encourage our shareholders to appreciate when considering the potential significance and value of the newly recognized strategic minerals. The REE oxide concentrations in assay approach those in known deposits, but what is most significant is the scale, that is, their occurrence in hydrothermal breccia which dominates through two drill intersections each spanning more than 600 vertical metres and located 200 metres apart within the core of a polyphase complex some 5 km’s across for which our reconnaissance drilling for copper and gold has only just begun to test.
We have a high degree of confidence in this lithium and REE discovery because of the correlation between independent XRF and geochemical assay data, as exemplified by yttrium, terbium and thorium. To further our understanding of this discovery, VR has initiated a second round of geochemical analyses to focus on full-suite REE detection, above and beyond the trace element indicator data currently in hand.
As with the drill program completed this past fall, VR will work continuously with the helicopter and geophysical companies now on site at H-K to ensure for the safety of all workers during the current gravity survey with regard to the evolving and ongoing COVID-19 global pandemic.
We look forward to providing future updates as we continue to advance our exploration at H-K.”

About Hecla-Kilmer
The Hecla-Kilmer complex is located 35 kms southwest of the Company’s Ranoke property in northern Ontario. It is located 23 km’s northwest of the Ontario hydro-electric facility at Otter Rapids, the Ontario Northland Railway, and the northern terminus of Highway 634 which links the region to the towns of Cochrane and Kapuskasing along the northern Trans-Canada Highway located some 100 km’s to the south.
The H-K property is large. It consists of 224 mineral claims in one contiguous block approximately 6 x 7 km’s in size and covering 4,617 hectares. The property is owned
Like the Ranoke property, H-K is located on provincial crown land, with mineral rights administered by the provincial Ontario Ministry of Energy, Northern Development and Mines (MENDM). There are no annual payments, but the MENDM requires certain annual exploration expenditures and reporting. The property falls within the Moose Cree and Taykwa Tagamou First Nations traditional territories.
Hecla-Kilmer (“H-K”) is a polyphase alkaline intrusive complex with carbonatite 4 – 6 km’s across, emplaced along the western margin of the crustal-scale Kapuskasing structural zone which bisects the Archean Superior Craton in northern Ontario. The opportunity for VR is to apply modern IOCG and carbonatite mineral deposit models and exploration technologies to H-K for the first time, ever. A shallow, six-hole diamond drill program was completed in 1970 as part of a regional base metal exploration program by Ashland Oil and Elgin Petroleum. One hole was abandoned, and only 854 m were completed in total in 5 holes, all on magnetic highs in the outer concentric zones of the complex. Selco Exploration Company completed two drill holes in 1981 on peripheral magnetic highs as part of a regional diamond exploration program, and intersected ultra-basic rocks and breccias in the outer, concentric zones of the polyphase H-K complex. A high resolution airborne magnetic survey was completed in the region for diamond exploration in 1993, after the afore-mentioned drilling.
