The project which is in Cote-Nord, covers 19,884 hectares, and directly borders Mason Graphite's advanced Lac Gueret project to the south.
Berkwood is targeting airborne and ground conductive anomalies at the South's Zone 1 location as part of this initial programme, where two distinct electromagnetic conductors appear to occur over a 2km strike length.
"I am pleased to provide confirmation that we have intersected graphite in all of the thirteen holes in our first drill program," Tom Yingling, the group's president and chief executive, told investors.
"The electromagnetic conductors have proven very effective in identifying mineralized targets for drilling," he added, also thanking the discovery team.
"I look forward to moving the drill over to our Zone 2 target and commencing drilling on it. In addition I look forward to our team developing an effective exploration strategy on Berkwood's recently acquired vanadium property as well as continuing work on our cobalt and lithium projects as well."
The firm also has well developed targets at Lac Gueret South's Zone 2, immediately south of the Mason Graphite claim boundary and along strike from the graphite zones of Mason Graphite.
Zone 2 has not been drilled yet but is fully permitted and drilling is planned for the upcoming phase 2 drill programme.
Berkwood said it had now submitted 381 samples to MS Analytical Laboratories in Langley, British Columbia.
It's been a busy period for the high tech minerals group. Yesterday, it told investors it had acquired the Roscoe vanadium property in Quebec, which consists of 40 claims totalling 21.89 sq km in an area of known iron-titanium-vanadium mineralization.
It was the site of historic work and more recent airborne surveys.
Berkwood is paying C$15,000 and 1.5mln shares to 1129961 B.C. Ltd to buy the project and will own 100% with no royalties attached.
Shares gained 7.94% in Toronto to stand at C$0.34.
