A total of nine holes were drilled in the Phase 3 drill programme with every hole intersecting visible graphite.

Of the nine holes drilled, eight of them intersected significant mineralisation with one hole having 17.37% Cgr over 130.55m with a true thickness of 87.5m, while grades have been returned as high as 33.88%.
Berkwood said the three drill programmes on its Zone 1 graphite body have found intercepts that support an evolving structural model of multiple recumbently folded horizon(s) hosting thicker and more consistent graphitic intervals of high grade and wide true thicknesses that suggests strong continuity in the system.
The graphite lies near surface to open-pit mineable depths similar to the depths drilled by Mason Graphite for its planned open pit development, which is about eight kilometres to the north-east.
"With the 130m intercept near surface and a length-weighted composite grade of 17.37% Cgr, the Phase 3 drill programme represents a success,” said Edward Lyons, a technical advisor to Berkwood.
“The importance of the thinner intersections is that they can mark the edges of thicker beds of graphite. Industry and metallurgical experience in highly metamorphic graphitic rocks has shown that the medium and lower graphite grade material can yield higher percentages of coarse flake graphite recovery, making these units potentially of similar economic value. The true widths and persistence of graphite in almost all of Berkwood's drill holes to date show the potential of the Zone 1 anomaly," he added.
