Margaret Lake Diamonds/Arctic Star Exploration move Lac de Gras project to drill-ready status

by Greg Klein | May 6, 2019

Three seasons of state-of-the-art techniques have a Northwest Territories diamond project ready for the rig. The Diagras joint venture of Margaret Lake Diamonds TSXV:DIA and Arctic Star Exploration TSXV:ADD has now undergone geophysical strategies that weren’t used by previous operators but proved successful at Kennady Diamonds’ (TSXV:KDI) Kennady North, another project in the prolific Lac de Gras diamond field. With a permit already in hand, the JV has drilling planned for spring 2020.

Margaret Lake holds the majority share of the 60/40 JV and acts as project operator.

Analysis of ground gravity, magnetic and electromagnetic surveys found compelling targets among 23 known kimberlites on the 22,595-hectare property. Among the examples are Black Spruce, where three distinct signatures from magnetic, gravity and EM data might represent different phases of the same kimberlite complex that could host different diamond grades and populations.

Jack Pine, one of Lac de Gras’ largest kimberlite complexes, revealed “a new kimberlite-like geophysical expression believed to have not yet been evaluated by drilling according to available public domain records,” the companies stated. Previous drilling at Jack Pine showed it’s “significantly diamond-bearing.”

The Suzanne kimberlite shows gravity and EM anomalies that likely weren’t adequately tested by a previous operator’s drill hole, therefore warranting further drilling.

Surveys over the HL02 kimberlite suggest “an untested gravity and EM target that breaks a diabase dyke,” the JV explained. “This is a classic compelling kimberlite drill target.”

EM anomalies at the Kong and Penelope kimberlites could represent untested kimberlites or kimberlite phases. Several other known kimberlites have yet to undergo modern geophysics, but remain open for surveys while next year’s drilling takes place.

Margaret Lake also has drilling planned for its recently optioned Kiyuk Lake gold property in Nunavut, just north of the Manitoba border. With analysis of detailed ground geophysics underway, the company plans a 5,000-metre program focusing largely on the property’s Rusty zone. Some historic, non-43-101 results from 2017 showed 26.48 g/t gold over 8 metres, 1.16 g/t over 38 metres, and 1.82 g/t over 122 metres. Margaret Lake may earn up to 80% of the 59,000-hectare property.

The company also holds a 100% interest in the eponymous Margaret Lake property, another Lac de Gras diamond project.
