GreenRoc Mining Plc (AIM: GROC), a company focused on the development of critical minerals projects in Greenland, is pleased to announce the first batch of assay results from drill core from the 2022 Phase Two drilling programme at the Company’s flagship Amitsoq Graphite Project in South Greenland (‘Amitsoq’ or the ‘Project’), one of the highest-grade graphite projects in the world.
The Company is also pleased to confirm the appointment of Niras a/s (‘Niras’), an experienced Danish/Greenlandic multi-disciplinary engineering consultancy, to undertake a Social Impact Assessment (“SIA”) at Amitsoq as GreenRoc focuses on fast-tracking the Project to mine development status.
· First assay results, from four of the 19 holes drilled during Phase Two drilling, which concluded in September 2022 at Amitsoq, have returned more world-class graphite grades at the Project.
· Assays of intersections of graphite ore from the main Lower Graphite Layer (‘LGL’) returned graphite grades of between 20.99% and 24.52% by weight (expressed as C(g) below) for mineable widths (larger than 2.0m).
· The Upper Graphite Layer (‘UGL’) varies between 17.29% and 20.92% C(g) for mineable widths (larger than 2.0m).
· The best intersection of a graphite layer was from hole AM_DD_017A, which returned a grade of 23.45% graphite over an intersection of 15.46m of the LGL, corresponding to 11.84m of true thickness.
· Results build on recent successful spheronisation tests, which demonstrated the suitability of Amitsoq graphite as feed material for electric vehicle (“EV”) battery anode production.
· Niras appointed to undertake a Social Impact Assessment at Amitsoq, a key precursor to a Mining Licence application in Greenland.
GreenRoc’s CEO, Stefan Bernstein, commented:
“This first batch of assay results from our Phase Two drill core confirms the continued high graphite content within the Amitsoq ore. To return grades of just under 20% graphite across the UGL and consistently in excess of 20% across the thicker LGL is truly remarkable and continues to showcase Amitsoq as a world-class asset with significant commercial potential. A particular standout result is hole AM_DD_017A, which returned a grade of 23.45% graphite over an intersection of 15.46m, corresponding to 11.84m of true thickness. This is particularly significant as this hole is located to the south-west of the drilled area, and the deposit remains open towards the south, west and north, giving us strong confidence of further upside potential.
“Based on the quality of the results we continue to receive from Amitsoq, we are naturally firmly focused on advancing the asset to development status. In support of this we are delighted to have signed a contract with Niras to undertake the SIA at Amitsoq. The Niras team has extensive experience in Greenland and has conducted several such assessments before. With both the SIA and the Environmental Impact Assessment (“EIA”) underway, we are now working steadily towards the submission of an exploitation licence application to the Greenland government, a key milestone in our road to production.”
Samples from graphite ore intersections of the first four drill holes at Amitsoq were sent from Greenland to the independent laboratory at ALS in Ireland for assays (Table 1 and Figure 1) during the middle of the drilling campaign. Each intersection of UGL and LGL was divided into smaller sample intervals of typically 0.5m length consisting of quarter drill core. The NQ core diameter is nominally 47mm.

The reported analytical values for entire intersections are averages calculated as weighted towards individual sample lengths along the sampled core.
Assay results from the remaining 15 drill holes are expected to be received by mid-December and will be reported when they become available. Crucially, results received to date from Amitsoq continue to confirm the commercial potential of the Project, as evidenced moreover by the recent successful spheronisation results announced on 8 November 2022, which demonstrated the suitability of graphite from the Amitsoq Island deposit as feed material for EV-battery anode production.

Social Impact Assessment
On 9 November 2022, the Company signed a contract with Niras to undertake a full SIA for the Amitsoq Project. Niras has substantial experience in conducting such studies, particularly in Greenland, and is familiar with the requirements of Greenlandic laws, frameworks and guidelines in relation to an SIA. The objective of the SIA, a substantial exercise which is expected to take several months to complete, is to ensure that a mining development maximises its benefits and minimises its potential negative impacts on society and local communities.
The formal approval of an SIA, together with an EIA and JORC resource capable of supporting a mining operation, are the necessary precursors to an application for a Mining (or Exploitation) Licence in Greenland. In respect of the latter, the Project has a Maiden resource of 8.3 million tonnes (Mt) at an average grade of 19.75% Cg with an upgrade in the Project’s resource tonnage expected.
BioApp Greenland, a Danish/Greenlandic-based contractor and environmental expert with extensive operational experience in Greenland, is also in the process of completing the reporting of the second year of baseline environmental studies which were carried out on site this summer. These results will feed into BioApp’s continuing work on the EIA.

C(g)% or Graphitic Carbon: Carbon may be present in rocks in various forms including organic carbon, carbonates or graphitic carbon. Carbon in rocks may be reported as fixed or total carbon (i.e., organic carbon + carbon in carbonate minerals + carbon as graphite) or as graphitic carbon or total graphitic carbon (or TGC) (i.e. total carbon – (organic + carbonate carbon)). In this report, graphite results are indicated as graphitic carbon or % C(g).
