An Exceptionally High-Grade Flake Graphite Project in Southern Greenland

Amitsoq Graphite, Greenland

The Amitsoq Graphite Project is located in the Nanortalik region of southern Greenland and has been confirmed as one of the highest-grade graphite deposits in the world.  The Project is owned and operated by GreenRoc’s wholly owned subsidiary, Obsidian Mining Limited under Mineral Exploration Licence 2013-06.

Successive field seasons have confirmed the presence of two high-grade flake graphite layers on Amitsoq through channel and grab sampling: the Amitsoq Island Deposit to the north, which is the site of a former graphite mine, and the recent mainland Kalaaq Deposit to the south, which has benefitted from extensions to the known surface expressions of graphite layers. In essence, the exploration target areas have yielded high grade data for extensive mineralised zones on surface.

A diamond core drilling programme in summer 2021 enabled GreenRoc to publish a significant maiden JORC resource in early March 2022 of 8.28 million tonnes (Mt) at an average grade of 19.75%, giving a total contained graphite content of 1.63Mt. For context, deposits with compliant resources above 20% contained graphite grade are scarce, with the average global grade of graphite resources being just 8.45% according to S&P Global.  By contrast, the average grade at Amitsoq is 19.75%, and this contains a lower graphite layer which has a JORC resource of 3.67Mt at a grade of 21.19% with 0.775Mt of contained graphite.

The consistency and true widths of the orebodies at the Amitsoq deposit bode well for future mining and processing operations.  Furthermore, it has been shown from previous metallurgical testing that this material can be upgraded to a more than 99.95% pure spherical graphite product, which is the requirement for EV batteries. Global consumption of this type of high purity spherical graphite is forecast to be at least 3 times higher by 2030 and 25 times higher by 2040, with supply shortages predicted in the near to medium term.

GreenRoc is focussed on advancing Amitsoq to the development phase as swiftly as possible and is confident that significant further upside remains. The deposit remains open along strike and down dip and the highly prospective Kalaaq Deposit is yet to be drilled.
