TORONTO, Nov. 18, 2021 (GLOBE NEWSWIRE) — Churchill Resources Inc. (“Churchill” or the “Company”) (TSXV: CRI) is pleased to announce that its Phase 1 Exploration Program at Taylor Brook in western Newfoundland has proceeded well and has identified and started to evaluate a magmatic Ni-Cu system on the property which appears to have significant scale.
- Historic drilling of the Layden Showing in 2008 returned 4.25 m of 1.63% Ni, 0.36% Cu and 0.027% Co in hole 08-TB-17
- Recent Churchill drilling and mapping indicate that Layden may be part of a much larger mineralized magmatic system of sulphide breccia structures within a gabbroic intrusive
- Sulphide-cemented breccia structures have been intersected in several locations over ~100m along the overall gabbroic intrusive thus far, at depths from surface to ~-200m.
- mineralized breccia structures appear to range from 5-15m wide with sulphide contents up to 40% (pyrrotite-pendlandite-chalcopyrite) locally over 10-20cm
- Assay results are expected from Churchill’s 2,477m Phase 1 drilling program towards the end of the year
Paul Sobie, Chief Executive Officer of Churchill remarked, “We are really excited by the drilling and surface mineralization at Taylor Brook, which indicate that we are intersecting lithologies and textures related to magmatic Ni-Cu deposits. We look forward to continuing to evaluate this magmatic system and potentially locating more massive styles of mineralization, as well as any other systems we may discover on the overall property.”
Taylor Brook Project
To date 13 core holes totalling 2,477m have been drilled as the Phase 1 program, of which several holes were positioned geologically to define the emerging magmatic system. Others were targeted on VTEM conductor plates, all of which have helped to establish a preliminary model for this portion of the overall property, as per this figure which shows current and historical drilling over unprocessed recently collected total field ground magnetics.
Drilling, mapping and geophysical surveys indicate that the mineralized outcrop at the original Layden Showing appears to be part of a much larger intrusive magmatic Ni-Cu system striking east-southeast and plunging to the southeast with significant thicknesses based on drill intersections. The Layden magmatic system is hosted by a discrete, magnetic, meta-gabbroic to meta-pyroxenitic intrusion within basement gneisses with the Ni-Cu mineralization taking the form of pods, thin horizons and blebs of pyrrhotite, pentlandite and chalcopyrite that brecciate the pyroxenite.
The sulphide-cemented breccia structures have been intersected in several locations over ~100m along the overall gabbroic intrusive at depths from surface to ~-200m. The mineralized breccia structures appear to range from 5-15m wide with sulphide contents up to 40% locally over 10-20cm with several separate zones of breccia within the Layden intrusion.
Bore Hole Electromagnetic (BHEM) surveys on all holes are being conducted to assist in planning deeper Phase 2 drilling. Logging and sampling of Phase 1 holes is nearing completion as well, a large suite of samples has been selected for geochemical analysis, petrography and in some cases, radiometric age dating to aid in understanding the host and intrusive rocks and mineralization event.
A heavy minerals sampling program along the western margin of the very large Taylor Brook Gabbro Complex which outcrops less than a kilometre east of the mineralized magmatic intrusive at Layden is currently underway. Drilling results are expected toward the end of 2021.
Florence Lake Project
A helicopter-borne VTEM and Horizontal Gradiometer Geophysical Survey is commencing at the Florence Lake Project in Labrador.
The Florence Lake Property contains Raglan-type ultramafic volcanic-hosted massive and disseminated sulphide nickel showings, and was last explored by Falconbridge and JV partners between 1990-1997 during which time approximately 6,250m of drilling was completed in 45 shallow holes. 1996 drill core is located on the property for relogging and sampling, whereas 1992-3, partly sampled core, is stored at NL Government core library in Happy Valley – Goose Bay. Highlights of that work included drill testing of the high-grade Baikie Showing where shallow drilling (<-100m depths) returned:
DDH FLK-92-02: 2.19% Ni, 0.22% Cu, 0.16% Co over 11.32 metres from 44.7 to 56m
DDH FLK-92-12: 1.33% Ni, 0.05% Cu over 13.5 metres from 83.0 to 96.5m
The Baikie Showing has demonstrated mineralized continuity over 110m of strike length from twelve drillhole intercepts and mapping, and is interpreted as a near vertically plunging subzone of disseminated, semi-massive and massive sulphide mineralization, possibly similar to the Raglan or Kambalda style of nickel deposits. Other showings along strike have generated +1.0% nickel grab samples or short drill intersections and need modern exploration work along with Baikie.
Churchill announced positive results of due-diligence resampling of the historical core in a news release dated October 7, 2021.
The technical and scientific information in this news release has been reviewed and approved by Dr. Derek H.C Wilton, P.Geo., FGC, who is a “qualified person” as defined under National Instrument 43-101 – Standards of Disclosure for Mineral Projects and independent of the Company. The Churchill drill core samples are half core samples laid out and split by qualified geologists and technicians under the direction of Senior Project Consultant Dawn Evans-Lamswood, P.Geo. at the Company’s drill camp near the property. The samples were placed in labelled, sealed plastic bags and periodically batches are delivered to Eastern Analytical for analysis. Standard OREAS 13b and blanks were inserted in the assay batches.
About Churchill Resources Inc.
Churchill is managed by career mining industry professionals and currently holds four exploration projects, namely Taylor Brook in Newfoundland, Florence Lake in Labrador, Pelly Bay in Nunavut and White River in Ontario. All projects are at the evaluation stage, with known mineralized Ni-Cu-Co showings at Taylor Brook, Florence Lake and Pelly Bay, and diamondiferous kimberlitic intrusives at White River and Pelly Bay. The primary focus of Churchill is on the continued exploration and development of the Taylor Brook and Florence Lake Nickel Projects.
