SnapshotAmitsoq is one of the highest-grade graphite deposits in the world.

PEA 2023 assumes mining and mineral processing of ore with a production of graphitic concentrate.

Mine plan assumes mining from the Lower Graphite Layer (LGL) only, leaving considerable resources from the Upper Graphite Layer (UGL) available for future production expansion or extension to the LOM.

Feasibility Study 2024 (FS) assumes the establishment of a downstream processing plant to produce graphite active anode material from graphite concentrate. FS has assumed that the anode plant operation will purchase the key input raw material, graphite concentrate.

On 9 December, 2025, the Government of Greenland has granted a 30-year Exploitation Licence for the Amitsoq Graphite Project.

Following the approval of the EIA and SIA reports by the Government of Greenland, Greenland Graphite (GreenRoc's subsidiary) will have until 31 December 2028 to submit a mining and decommissioning plan.

Summary:

Amitsoq is one of the highest-grade graphite deposits in the world with a combined Measured, Indicated and Inferred Resource, sufficient to sustain several decades of mining.

Significant further resource upside exists at Amitsoq as the Amitsoq Island Deposit is open in at least two directions, with potential for considerable further expansion via the similarly high-grade Kalaaq Mainland Deposit as well as a series of other high-grade targets within GreenRoc's licence package.

Amitsoq has two main orebodies: Upper Graphite Layer (UGL) and Lower Graphite Layer (LGL).

Historic graphite occurrences have also been confirmed in four new zones of interest, broadly forming a north-south tract some 30km long. The four zones comprise Nanortalik Island, Tusardluarnaq North and Thomsen’s Island, which sit within the southern portion of the licence, and Amitsoq Valley Bed, which lies ~7km NE of the established Amitsoq Island deposit.

On Nanortalik Island, graphitic grades of 23.4% C(g) to 32.5% C(g) have been reported from eight samples over a strike length of ~800m and the graphite bodies remain open along strike to the north and south. At Amitsoq Valley Bed, a new 1km long zone of graphite-bearing rocks with values up to 24.9% C(g) has been identified.

Consistently high-grade graphite intersections have been confirmed with significant mineable widths (more than 2.0m true thickness) present within graphite layers, consisting of the Lower Graphite Layer (‘LGL’) and Upper Graphite Layer (‘UGL’). The LGL has a maximum minable thickness of >20.77m running at 23.32% graphite (drill hole AM_DD_035).

The consistency of the very high graphite grades in both of the LGL and UGL ore bodies show that Amitsoq has the potential to be a significant graphite producer. Crucially, the UGL orebody remains open towards the west and south, while the LGL remains open towards the south, west and north, providing significant further upside opportunity.
