Vancouver, BC - TheNewswire - September 28, 2023 - VR Resources Ltd. (TSX.V:VRR) (FSE:5VR) (OTC:VRRCF), the "Company", or “VR”, has received complete results from caustic fusion and mineralogy for all three drill holes completed into the kimberlite breccia pipe complex on its Northway property in Northern Ontario.

Microdiamonds were recovered in 2 separate intervals within drill hole NW23-003, the last of the three first-pass drill holes into the 1.2 km magnetic anomaly at Northway. The intersection spanned 354 metres of kimberlite, for 723 kg of sawn NQ (47.6mm diameter) sample material. There were no microdiamonds in 173 kg from NW23-002. Attributes for all four of the microdiamonds recovered in Hole 003 are the same as the microdiamond in Hole 001:

• transparent, colourless; 

• clear, free of inclusions, and; 

• fragment of a larger diamond. 

A +106 micron microdiamond was recovered at 335 m, with 3 additional +75 micron diamonds found from 488 – 510 m (Table 1). They are hosted in pyroclastic kimberlitic breccia, KPK rock, characterized by:

• Concentrated chrome-diopside xenocrysts (core photographs in Figure 2); 

• Xenoliths of dunite, pyroxenite, and glimmerite (core photographs in Figure 3), and; 

• Autoliths of KPK rock (core photographs in Figure 4).  

 

Importantly, phlogopite xenocrysts and mineral grains within xenoliths plot within the kimberlite field on the Ti-Al plot (Figure 5), and in the kimberlite-orangeite field on the Al-Fe plot, consistent with hole 001. Further, titanium-potassium richterite in magmaclasts indicate an upper mantle source for the kimberlite.

 

Holes 002 and 003 were collared at the same site located approximately 450 m to the northwest of Hole 001 located near the eastern margin of the breccia pipe complex where a microdiamond was recovered in the crater facies of kimberlite mudstone at the top of the pipe (see NR23-18; Sept. 12, 2023).  As such:

• Microdiamonds are present across 600 m of the breccia pipe complex (map in Figure 6), and; 

• Microdiamonds are present over 220 vertical metres, starting at the top (profile in Figure 7).  

 

The boundary conditions for the 1.2 magnetic anomaly at Northway are consistent amongst an array of different plan maps and 3D inversion block models.  That said, the new drilling shows that Northway may be either: a complex of separate, adjacent breccia pipes as implied in Figure 6, or; a single, rooted pipe that fans upwards into complex geometries at the top as implied in the profile in Figure 7.  Regardless:

• Hole 001 transected only 30m of the top of the breccia pipe complex before the drill hole caved and was abandoned; the KPK rock below the maar-facies with microdiamonds is untested, and; 

• A longer intersection of pyroclastic kimberlite breccia was achieved in hole NW23-003 located some 450 m to the northwest, but the breadth of the magnetic center remains untested. 

 

From VR’s CEO, Dr. Michael Gunning, “It’s really quite something; Northway has produced microdiamonds in two of the first three reconnaissance drill holes ever put into the large breccia pipe complex, and more, both holes are arguably yet incomplete in terms of their vertical and lateral transect of the kimberlite.

 

Scale is important.  Fragments of clear, transparent and inclusion-free diamonds occur across some 600m of the breccia pipe complex, and over 220 metres vertically starting from the crater facies at the top.

 

Composition is equally important. Like in Hole 001, the composition of the pyroclastic kimberlite diatreme breccia (KPK) in Hole 003 falls within the kimberlite–orangeite compositional range, with Ti-K richterite grains indicative of an upper mantle origin for the pipe.

 

The results from the first three reconnaissance holes underscores the diamond potential at Northway in relation to the sheer volume of the breccia pipe complex itself, and in relation the number of targets around it, never previously explored or drilled and potentially representing a new field of Devonian-aged, diamondiferous kimberlite pipes in the northern Superior craton in northern Ontario, and located along the Ontario Northern railroad.

Compositional studies for Hole 003.

 

Initial results from two out of 13 samples of pelletal, accretionary diatreme breccia from drill hole NW23-003 were obtained by petrology and analysis by an electron microprobe (EMPA) equipped with an Energy Dispersive Spectrometer (EDS) by Renaud Geological Consulting Ltd. (RGC) based in London, Ontario, with extensive experience in kimberlite exploration, geology and mineralogy.  

 

Preliminary observations include:

1. Ti-K richterite, a mantle sourced amphibole, in a glimmerite magmaclast nodule; 

2. Fine grained diopside, a clinopyroxene, containing 0.15 wt% chrome; 

3. Deep crustal glimmerite xenoliths composed of massive phlogopite are common; 

4. Phlogopite xenocrysts and mineral grains in xenoliths plot within kimberlite fields on Ti-Al plots  (Figure 5), and in kimberlite-orangeite field on Al-Fe plots;  

5. Accretionary lapilli are mainly biotite-phlogopite (now illite), surrounded by illite, dolomite-ankerite, F-apatite, and perovskite, and; 

6. Pelletal lapilli are hosted in a groundmass of carbonate, Ti-Ba-biotite-phlogopite including glimmerite nodules, F-apatite, Al-spinel, clinopyroxene, Nb-ilmenite, monazite and perovskite. 

 

Technical Information

 

Summary technical and geological information for the Company’s various exploration properties is available at the Company’s website at www.vrr.ca.

VR submits sawn drill core to the Saskatchewan Research Council through Geoanalytical Laboratories Diamond Services located in Saskatoon Saskatchewan (the “SRC”) in roughly 8 kg aliquot samples for sodium hydroxide dissolution and fusion. Residue and microdiamonds are sieved down to 75 microns, weighed, and assessed for colour, clarity and shape. Analytical results are subject to industry-standard and NI 43-101 compliant QAQC sample procedures, including the systematic insertion of tracer diamonds into each sample ahead of caustic fusion at the laboratory by the SRC. The SRC is an independent mineral processing facility which is accredited to the ISO/IEC 17025:2017 standard by the Standards Council of Canada as a testing laboratory for specific tests.

Technical information for this news release has been prepared in accordance with the Canadian regulatory requirements set out in National Instrument 43-101. Justin Daley, P.Geo., VP Exploration and a non-independent Qualified Person oversees and/or participates in all aspects of the Company’s mineral exploration projects, and the content of this news release has been reviewed on behalf of the Company by the CEO, Dr. Michael Gunning, P.Geo., a non-independent Qualified Person.

About the Northway Property and Project

 

The Northway property is located in northern Ontario. It is approximately 12 km northeast of the Company’s REE critical metal discovery at its Hecla-Kilmer project.

 

Exploration is based out of a camp at the hydroelectric facility at Otter Rapids located about 50 km to the southeast of Northway. Provincial Highway 634 provides road access to Otter Rapids from Smooth Rock Falls, located at the junction of HWY 634 with the Trans-Canada Highway. The property itself is just 15 km west of the Ontario Northern railway (ONR) which provides service to the communities on James Bay.

 

The nearest town is Moosonee, located on tidewater at James Bay some 125 km to the north. Kapuskasing is about the same distance to the southwest, located on the Trans-Canada Highway (Provincial HWY 11).

 

The Northway property consists of 64 contiguous claims in a single, 4 x 7 km block 1,315 ha in size.  It was expanded to a district-scale project by staking directly 284 new claims in 19 additional properties covering magnetic anomalies near Northway and proximal to the ONR line, within an area of 50 x 70 km overall.

 

The properties are owned 100% by VR. There are no underlying payments or interests on the property and no royalty interests because the property was staked by VR directly.

 

Northway is located on crown land in northern Ontario, with mineral rights administered by the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry (“MNDM”). There are no annual payments, but the MNDM requires certain annual exploration expenditures and reporting. The property falls within the traditional territories of the Moose Cree and Taykwa Tagamou First Nations.
