Mountain Province Diamonds Returns 40-Metre Kimberlite Intercept, 40 metres from known Tuzo Resource

12.06.2023 | 23:01 Uhr | CNW
Positive Drilling Results from the Hearne Kimberlite at the Gahcho Kué Mine

TORONTO, June 12, 2023 - Mountain Province Diamonds Inc. ("Mountain Province", the "Company") (TSX: MPVD) announces the discovery of additional kimberlite, approximately 40 metres to the northeast of the modeled Tuzo kimberlite. In addition, the drilling of the Hearne Deep and the Northwest Extension has seen multiple intercepts of up to 287 metres of kimberlite.

The Hearne Northwest Extension was identified in late 2021 when a kimberlite exposure (25 meters across) was encountered in a lower bench face during routine mining operations. Drilling programs in 2022 indicated that a significant volume of previously unknown kimberlite could exist, with ten of sixteen drillholes reported kimberlite intersections up to 114 meters in the extension (see news releases, July 18 and November 30, 2022). In the 2023 program ten of eleven drillholes collared within and outside of the Hearne pit have intersected kimberlite with the longest intersection being 287 meters.

Mark Wall, the Company's President and Chief Executive Officer commented:

"These latest results at Hearne confirm that a significant volume of kimberlite exists in the Northwest Extension. Combined with our earlier results, we now have 21 drillholes that define the extension below the final pit and to the northwest. We are actively engaged with our operating partner De Beers to look at ways to recover this deeper kimberlite by underground mining."

In the present program, seven drillholes were collared outside of the pit and four were collared on kimberlite within the pit to test the width and depth of the extension respectively. A summary of the latest drilling results is provided below.

(HK = hypabyssal kimberlite; TK = fragmental kimberlite; HKt = hypabyssal kimberlite transitional to TK; TKt = fragmental kimberlite transitional to HK.)

The drillhole locations and traces for this phase of drilling are shown as red lines in the images below, with previous drill traces shown as gray lines. Drillholes within the pit are shown as red circles. Insets show the shape of Hearne prior to discovery of the extension. The internal geology of Hearne is shown with blue indicating hypabyssal kimberlite (HK/HKt) and yellow and green indicating fragmental kimberlite (TK/TKt). The modeled outer contacts and internal geology for the Northwest Extension are speculative at this time and will be adjusted as the results of detailed logging and analysis are received.

Following on the discovery and delineation of the Hearne Northwest Extension, drilling to look for a similar extension has been started at Tuzo. Limited historical drilling at Tuzo has confirmed kimberlite to a vertical depth of over 700 meters.

Based on the northeast-directed downward ramping of the 5034 kimberlite and its proximity to Tuzo, a single drillhole was collared east of Tuzo to test for a northeast extension. The image below shows the relationship of drillhole MPV-23-632C to the 5034, Tuzo and Wilson kimberlites.

Drillhole MPV-23-632C intersected TKt/HKt kimberlite from 669.77-710.00 meters, and is located roughly 40 meters northeast of the Tuzo kimberlite. The kimberlite phase in Tuzo that is nearest to the intersect is modeled also as TKt (shown in yellow in the image). Logging and mineral chemistry of the drill core is underway to confirm whether it is similar in detail to Tuzo.

Mark Wall, the Company's President and Chief Executive Officer commented:

"While the drilling for Tuzo is early stage and is still underway, we are encouraged by the width of the kimberlite intersection and its similarities to Tuzo based on initial logging. We and our partner De Beers will consider further drilling if the detailed work on this hole continues to return positive results."

About the Company

Mountain Province Diamonds is a 49% participant with De Beers Canada in the Gahcho Kué diamond mine located in Canada's Northwest Territories. The Gahcho Kué Joint Venture consists of several kimberlites that are actively being mined, developed, and explored for future development. The Company also controls over 113,000 hectares of highly prospective mineral claims and leases surrounding the Gahcho Kué Mine that include an Indicated mineral resource for the Kelvin kimberlite and Inferred mineral resources for the Faraday kimberlites. Kelvin is estimated to contain 13.62 million carats (Mct) in 8.50 million tonnes (Mt) at a grade of 1.60 carats/tonne and value of US$63/carat. Faraday 2 is estimated to contain 5.45Mct in 2.07Mt at a grade of 2.63 carats/tonne and value of US$140/ct. Faraday 1-3 is estimated to contain 1.90Mct in 1.87Mt at a grade of 1.04 carats/tonne and value of US$75/carat. All resource estimations are based on a 1mm diamond size bottom cut-off.
