Amitsoq Graphite Project Update

Grant of Additional Exploration Licence

GreenRoc Mining Plc (AIM: GROC), a company focused on the development of critical minerals projects in Greenland, is pleased to announce that the Government of Greenland has granted exclusive Mineral Exploration Licence ("MEL") 2022-03 to the Company. The granted licence area encompasses a potential southerly extension to the Kalaaq deposit as well as several known graphite showings which are separate from both the Amitsoq Island and Kalaaq deposits.

GreenRoc's Amitsoq Graphite Project in southern Greenland ("Amitsoq") is one of the highest-grade graphite projects in the world.

Stefan Bernstein, GreenRoc's CEO, commented : "The grant of this licence allows us to consolidate our landholding around the Kalaaq deposit, including the area immediately south of the known Kalaaq graphite discovery, in addition to securing new zones which contain graphite-rich showings. These areas have not been subject to modern exploration techniques and only a few have been sporadically sampled in the past. As such, they offer GreenRoc the potential to reveal new graphite discoveries contiguous to Amitsoq, proven to be one of the highest-grade graphite projects in the world.

"With this additional ground now included in GreenRoc's new Exploration Licence, the team and I are excited about the future potential for identifying an additional mineralised graphite zone outside the primary target zones to the south of the Kalaaq Deposit. In my view, this provides further evidence that the Amitsoq Project has the potential to be one of the most strategically valuable graphite assets globally.

We look forward to providing further news flow from Amitsoq during this summer as we seek an upgrade and increase of the existing Mineral Resource there."


The new exploration licence, MEL 2022-03 (Figure 1), covers a total of 68km(2) and extends the current exploration licence areas held by GreenRoc to encompass both the ground in the most northerly section of Amitsoq Island as well as ground to the south of the Kalaaq graphite discovery. The southern portion of the new licence area includes several known graphite showings and one old graphite working, Sissarissoq, and is within the vicinity of the town of Nanortalik, Greenland's southernmost town.

NDZ and NHP Target Zones

As detailed in the RNS of 9 November 2021, a potential new area, termed the New Domain Zone ('NDZ'), with a grab sample grade of 32.1 C(g)%, was identified in the Company's 2021 field work, 1km to the south-east of the current Exploration Target Boundary (see Figure 2) and a further 540m along strike from the graphite horizon mapped during the 2017 campaign.

Further, the NHP Zone (see Figure 2) is a new discovery which was identified during the 2021 field programme. It extends the graphite mineralisation for a strike distance of 1.3km southwards and thus expands the previously reported exploration target zone. The NHP Zone is exposed over an area 50m wide and 200m long. The 4-metre horizon which was trenched and sampled graded 17.43 C(g)%. The NHP Zone is a primary target for further trenching and channel sampling during the 2022 field season.

Both the NDZ and NHP targets indicate the potential for additional mineralised graphite zones outside the primary target zones to the south of the Kalaaq Deposit. The ground south of the NDZ and NHP Zones is now fully encompassed within MEL 2022-03.

Nanortalik Island (Sissarissoq) Prospects

Two occurrences have been reported historically, approximately 200m apart, on Nanortalik Island 2.5km southwest of Nanortalik town (see Figure 3). The southern occurrence consists of two outcrops about 100 m from the coast. Historical trenching and sampling here recorded 280m(2) of mapped exposure, with less than 0.5m of overburden and a 1.5m thick band outcropping for 30m. A single analysed sample graded 24% graphite.

The northern occurrence is about 200-300m inland and is reported to host four types of graphite: breccia type; disseminated graphite in sulphide-rich schist; conglomerate with clasts of granite and a graphite-rich matrix of iron-oxides massive and amorphous graphite with fractured zones. Testwork and petrological assessment of five samples from this occurrence are reported to have returned 11-17% graphite.

With this new exploration licence, GreenRoc has expanded its landholding to encompass several, largely untested graphite occurrences which have been shown by earlier studies to contain high-grade graphite ore. As part of the Company's 2022 field campaign, a number of these occurrences will be sampled and studied to test their graphite quality and determine the potential size of the deposits.

As announced in the RNS dated 6 July 2022, GreenRoc has commenced its drilling programme at the Amitsoq Island deposit with the aim of further defining and significantly expanding the graphite resource there.
