As work resumes at Diagras, Margaret Lake Diamonds TSXV:DIA now returns to a second front in its search for Northwest Territories gems. On May 30 the company announced a new geophysics program had begun at Diagras, coinciding with a drill campaign that started earlier this month at the company’s Margaret Lake project.
The Diagras agenda calls for ground gravity, magnetic and EM surveys around known kimberlites, as well as around potential kimberlites suggested by earlier geophysics.
The strategy will employ techniques that weren’t used when De Beers explored the area but have since proven successful elsewhere. Some examples include two other Lac de Gras-region projects, Mountain Province Diamonds’ (TSX:MPVD) Kennady North and Peregrine Diamonds’ (TSX:PGD) Tli-Kwi-Cho DO-27/DO-18 kimberlite complex, Margaret Lake stated.
The company holds a majority interest and acts as operator on the 18,699-hectare Diagras property in a 60/40 joint venture with Arctic Star Exploration TSXV:ADD. The project sits 35 kilometres from Canada’s largest diamond producer, the Diavik mine of Rio Tinto NYSE:RIOand Dominion Diamond Mines.
Margaret Lake’s 100%-held, 23,199-hectare Margaret Lake property lies nine kilometres north of the De Beers/Mountain Province Gahcho Kué diamond mine and two kilometres from Mountain Province’s Kelvin and Faraday deposits.
Last year’s Diagras work found “gravity and EM anomalies proximal to known magnetic kimberlites that constitute compelling drill targets,” Margaret Lake stated. Among areas of special interest is Jack Pine, one of the largest kimberlite complexes in Lac de Gras. Previous drilling has revealed diamonds, while an area of further kimberlite potential has yet to be drilled.
Additionally, gravity anomalies near the property’s Black Spruce kimberlite show similarities to other kimberlites in the region.
Meanwhile Margaret Lake has a rig testing six kimberlite targets on the company’s namesake property. Each target shows a gravity low, bedrock conductor or both. The company interprets those characteristics as potentially representing kimberlite.
Last month Margaret Lake closed a $495,500 first tranche of a private placement offered up to $2.2 million.
