Successful Meetings Held with Community and Minister for Mineral Resources
GreenRoc Mining Plc (AIM: GROC), a company focused on the development of critical minerals projects in Greenland, is pleased to announce the results of purification test work carried out by GreenRoc’s technical consultants, ProGraphite GmbH (‘ProGraphite’) on spheronised graphite produced from an Amitsoq graphite sample. The test work achieved purity of 99.97% using alkaline purification, which exceeds the purity required to produce spheronised graphite used in the manufacturing of anodes for electric vehicle (“EV”) batteries.
The Company also reports that a series of positive and successful meetings have taken place in Greenland this week between CEO Stefan Bernstein and various project stakeholders including the local community at Amitsoq, the Minister for Mineral Resources and Justice and the newly established Government body, NunaGreen, which is leading the transition to carbon-neutral energy in Greenland.
Finally, GreenRoc provides a brief update on the status of Thule Black Sands (“TBS”) test work and resource assessment.
· A graphite sample from the Lower Graphite Layer (“LGL”), successfully spheronised last autumn, was subjected to purification tests using sodium hydroxide and reached a purity of 99.97%.
· Amitsoq graphite thereby surpasses the 99.95% purity required for spheronised graphite used in the manufacture of anodes for EV batteries.
· An information meeting in Nanortalik between the local community, GreenRoc’s CEO, Stefan Bernstein, and Niras, (the Company’s specialist sustainability consultant), in preparation of the Amitsog Social Impact Assessment (“SIA”). Meetings were also held with other local stakeholders, including industry representatives, the trade union, hunters’ organisation and representatives from the Municipality of Kujalleq.
· GreenRoc’s CEO, Stefan Bernstein, met in Nuuk with Aqqaluaq B. Egede, Minister for Mineral Resources and Justice and Permanent Secretary Jørgen Hammeken-Holm. The Minister expressed strong support for the Greenland mineral exploration industry in general and specifically for the Amitsoq Graphite Project.
· GreenRoc’s CEO, Stefan Bernstein, also met with representatives of the new Government body NunaGreen to discuss carbon-neutral energy sources to meet the energy needs for commercial operations at Amitsoq.
· Coarser grain fraction (> 1mm) from TBS drill samples to be tested for ilmenite content prior to finalisation of assays and resource assessment. The material larger than 1mm was initially discarded from the analytical work, though potentially containing appreciable amounts of ilmenite.
GreenRoc’s CEO, Stefan Bernstein, commented:
“This confirmation that our spheronised graphite, produced from concentrate from the Lower Graphite Layer at the Amitsoq Island deposit, can be purified to an exceptional 99.97% purity using a preferred alkaline purification route is a very significant milestone for our flagship project. It demonstrates that our graphite is suitable for processing into anode-grade spherical graphite, a key raw material in the manufacturing of batteries for electric vehicles.
“This week I held a series of very constructive meetings in southern Greenland with key Community and Government stakeholders in our Amitsoq Project. I was greatly encouraged by what I felt to be the overwhelmingly positive engagement I was met with, concerning the Amitsoq project. I have high expectations that our Amitsoq project can bring real value to Nanortalik and the Municipality of Kujalleq and I very much look forward to working with all stakeholders over the coming years as we plan the mine reopening, and thereafter.”
Successful Purification Test Results
After the successful micronisation and spheronisation test work conducted on LGL graphite material in the autumn of 2022, which was announced on 8 November 2022, the next step was to assess whether that spheronised graphite could be purified to at least 99.95%, that being the requirement for anode-grade material.
Purification test work had previously been carried out by ProGraphite in 2021, where they ran a series of tests on graphite concentrates and found that a high degree of purification could be reached using hydrofluoric acid, which is the standard method for purification. Because of the toxicity of hydrofluoric acid, ProGraphite also conducted purification tests using sodium hydroxide (an alkali) and found that the required purity could also be achieved with this agent.
These tests were repeated recently by ProGraphite on spheronised graphite material produced from LGL drill core. Several tests were conducted, and it was found that a leaching at a relatively low temperature of 250°C resulted in a purified graphite product containing 99.97% graphite. Levels of unwanted elements such as Fe, Cu and Cr were all at very low levels of 15.4ppm, 0.8ppm and 0.2ppm respectively.
Meetings in Nanortalik
On 17 January 2023, GreenRoc CEO Stefan Bernstein held an information meeting at the Culture House in Nanortalik, South Greenland. Nanortalik is the town closest to Amitsoq, lying only 20km to the south. Specialist consulting firm Niras, which is conducting the Social Impact Assessment for the Company, was represented by Director Gertrud Øllgaard. Stefan Bernstein gave an overview at the meeting of GreenRoc’s activities in 2022 and its plans for Amitsoq in the light of the positive outlook both for the graphite deposit at Amitsoq and the growing global graphite market. There was considerable interest in the Project and many pertinent questions asked, mainly relating to job prospects whether in the development, construction or production phases of the Project.
Meetings were also held with representatives of the Municipality of Kujalleq responsible for youth, recreational and sports activities in Nanortalik, as well as with representatives from the local fishing/hunters’ organisation (KNAPP), the workers’ union (SIP) and with several private service industries. Important viewpoints relating to future mining activity at Amitsoq were expressed and discussed.

Meeting with Ministry of Mineral Resources and Justice
On 16 January 2023, CEO Stefan Bernstein met in Nuuk with Minister for Mineral Resources and Justice, Aqqaluaq B. Egede and Permanent Secretary for same ministry, Jørgen Hammeken-Holm. During a very positive discussion, GreenRoc’s CEO presented the Company’s plans for advancing the Amitsoq graphite project to production and the Minister in turn expressed his views on how the mineral industry could contribute in a positive way to the development of the towns and villages in South Greenland. The Minister stressed that the Naalakkersuisut (Government of Greenland) has a positive attitude towards the exploration and mining industry in general and he expressed strong support specifically to the Amitsoq graphite project. The important subject of renewable energy sources to supply both the mines and the towns in South Greenland was also discussed.
This latter issue was also discussed during a meeting the same day with NunaGreen, which is a newly established Governmental body which seeks to help Greenland transition away from the use of fossil fuels and instead to exploit the country’s formidable hydropower potential in order to underpin Power-to-X plants and possible other energy-intensive plants – some of which could well be in the mineral sector. Other options presented were a combination of smaller hydropower plants supplemented with wind turbines and tidal-water turbines, all of which could be exciting solutions delivering a CO2-neutral mining operation at Amitsoq.

Re-analysis of Thule Black Sands (“TBS”) samples
As announced on 26 September 2022, the drill results from the TBS Ilmenite Project were delayed due to the requirement for additional analytical work to be carried out. An upper screening of 1.0mm had initially been employed, which excluded a significant mass of potentially ilmenite-bearing material, the ilmenite being locked up in a dolerite matrix. This locked-up ilmenite will accordingly be subjected to a grinding, attritioning and a separation test work programme to determine whether it is recoverable to produce and in what grade and quality. This work is anticipated to commence by the end of January 2023, with results to be delivered approximately 6-8 weeks after commencement.
Following the completion of this next round of test work, the Company will be in a position to report final assay results from the drill programme and then proceed with the finalisation of a revised resource assessment for TBS.
Ilmenite is an iron-titanium oxide mineral and is the primary feedstock for the production of titanium metal and titanium dioxide, a widely used pigment.
