GreenRoc Mining plc announced it had doubled the drilled graphite deposit at the Amitsoq project in southern Greenland.
PHASE II
Phase II drilling began on 2 July 2022 with the aim of testing the extension of the known graphite layers before establishing a revised and higher category resource.
As at 14 August 2022, the company had completed nine holes for 1,360m.
EXTENSIONS
All the holes reached target depths and intersected the targeted graphite layers.
The drilled extent of the deposit footprint has doubled and remains open towards the northwest, west and southwest, said GreenRoc.
The company reported an extension to the west by some 100m and to the northwest by 150m “essentially doubling the deposit footprint”.
The deposit remains open towards the northwest, west and southwest.
THICKNESS
The company added that several intersections were at least as good as those obtained in the 2021 Phase I drill programme, confirming the “significant thickness of both the upper graphite layer (UGL) and lower graphite layer (LGL)”.
Phase I results returned up to 23.01% C(g) in the LGL and up to 19.83% C(g) in the UGL.
To date, GreenRoc has drilled 16 intersections of UGL and LGL greater than 3m each.
All holes have at least one mineable graphite layer intersection greater than 5.25m.
GreenRoc said that drilling to date gave “strong confidence” that the company could establish a higher-tonnage and higher-category resource ahead of a feasibility study.
The drilling programme is due for completion by the end of September.
SUBSTANTIAL
Chief executive Stefan Bernstein described the results as highly encouraging.
“These preliminary drill results are particularly exciting as most of the holes are placed further west of the holes drilled in 2021, suggesting a substantial extension to the graphite layers and indicating that the deposits are still open down-dip and to the northwest, west and southwest.
“Alongside this, we are currently drill testing the northern extension of the graphite layers, the results from which we look forward to sharing in due course.
“One final but very positive point is that the core is mostly very solid, which bodes well for stable mine construction as we look to advance Amitsoq to development status.”
