The work is aimed at improving the understanding of how the graphite mineralization at its Lac Gueret zone 1 discovery is distributed, and to help in extending the existing geological model, ahead of informing targets for a drill campaign.
MALM is an older electromagnetic technique that operates by placing a DC current electrode in a known, readily chargeable horizon from a downhole location and tracing the electric current distribution via either on-surface or in-drill-hole placed receivers.
"I am very pleased to have mobilizing the MALM survey: This application of geophysics is targeted specifically to inform what we hope is the next drill program required for the company to prepare a resource model that will enable the Berkwood to undertake a preliminary economic assessment of Lac Gueret," said Tom Yingling, president and chief executive officer.
"We are focused on advancing the zone 1 discovery with maximum efficiency, and the MALM survey is a key tool in our quest to most effectively model the mineralization."
Lac Gueret South lies in Cote Nord, which is a three-hour drive from Baie-Comeau in an area of very good infrastructure, such that the property is accessible by road year-round.
The project lies directly south of Mason Graphite's advanced Lac Gueret project.
At Lac Gueret South's zone 1, two distinct electromagnetic conductors appear over a 2km length and 50 metres to 600 metres in width as defined by airborne electromagnetic geophysics.
Three separate drill programs have been carried out on Berkwood's zone 1 graphite body for a total of over 4,000 metres.
All 27 holes have mineralization and 26 holes of these have intersected significant graphite.
On the company's airborne EM anomaly, it has drilled an area about 300 m by 300 m, leaving a large anomalous area that is as yet untested by drilling.
