GreenRoc Mining identifies ‘significant graphite extensions’ at Kalaaq Deposit

(GROC ) has identified significant graphite extensions from a field programme at the Kalaaq Deposit, part of the Amitsoq Graphite Project undertaken in July and August 2021.
Specifically, substantial zones of mineralisation were both confirmed and extended at the Kalaaq Deposit which is located on the Greenlandic mainland and due south of GreenRoc’s 100% owned Amitsoq Graphite Project, one of the highest-grade graphite projects globally.
The field exploration was conducted to sample mapped graphite horizons that had been identified in previous field campaigns, and to explore the wider area for new discoveries.
Exploration work consisted of field mapping, trenching, channel sampling, grab sampling and electromagnetic (EM) surveys using a portable beep mat. The Company informed investors that beep mat results are still being processed and that they will be reported when received.
New zones of mineralisation were confirmed while the programme also reinforced previously identified zones achieved through channel sampling, grab sampling and beep mat surveys.
The projection of the Upper Graphite Zone (UGZ) that was identified in 2017 was extended 360m to the south and is open along strike while the Lower Graphite Bed was also extended 300m along strike to the north where values of up to 33.1 C(g)% have now been recorded.
The newly discovered Niels Hede Pedersen (NHP) Zone has now extended the identified graphite mineralisation of the BLZ Zone a further 1.3km and again is open on strike.
A potential new area, termed the New Domain Zone (NDZ), with a grab sample grade of 32.1 C(g)%, has been identified 1km to the south-east of the current Exploration Target Boundary and a further 540m along strike from the graphite horizon mapped during the 2017 campaign.
The Company said this sample indicates the potential for an additional mineralised graphite zone outside the primary target zones on the western side of the Kalaaq Deposit.
GreenRoc’s CEO, Kirk Adams, commented: “This summer’s campaign at the Kalaaq Deposit has been highly successful in extending the strike lengths of the known mineralised zones, discovering new zones of mineralisation, and identifying high grade samples outside of the Exploration Target area. The assay values from the sampling programme range from 17.43 to 33.1 C(g)% and this confirms our faith that this is an extensive high-grade graphite area.
“The extensions we have identified outside the current Exploration Target area, which was based on the 2017 geological mapping and sampling programme, are particularly exciting as they indicate significant additional potential. This field campaign gives GreenRoc the platform to design a drilling programme which will target the identification of the third dimension of the mineralised zones that have been now brought into focus by this year’s fieldwork.”
During a recent site visit, GreenRoc said the average grade in the Kalaaq area from channel sampling to date is 25.6% contained graphite. As a result, GreenRoc told investors that it would create a drilling plan with the objective of declaring a maiden resource at Kalaaq.
In addition, GreenRoc said the recent fieldwork at Kalaaq has revealed additional graphite targets, which will be reported on fully in due course, upon receipt of laboratory assays.
Last month, the Company said a recent site visit to the Amitsoq Graphite Project in Southern Greenland had confirmed drill pad locations ahead of the company’s next drilling programme.
GreenRoc, which was created to buy the spun-out assets of Alba Mineral Resources, intends to utilise its assets in Greenland to become a key supplier of critical, high-demand minerals.
Its portfolio of assets in Greenland include a range of 100% owned projects acquired from Alba Mineral Resources including; the Amitsoq graphite project, the Thule Black Sands ilmenite project, the Melville Bay iron project and the Inglefield multi-element project.
During a recent management site visit to Amitsoq, which is considered ‘one of the highest-grade graphite projects globally’, underground mine workings were inspected.
