About us

GreenRoc is focused on fast-tracking the development of its flagship Amitsoq Graphite Project to develop a new, responsibly mined, source of high-quality graphite that can support the rapidly growing EV battery market.

GreenRoc is further aiming to build capability to process Amitsoq graphite into anode ready material.

Graphite is projected to be in severe deficit before the end of this decade (Source: BMI, 2023).

Graphite is considered a critical mineral by the USGS and a strategic critic mineral by the EU.

Graphite is essential for the energy transition as it makes up the active component in Li-ion battery anodes, with an electric car battery containing 40-80 kg of purified, coated, spherical graphite (cSPG).

As a result, demand for graphite is rapidly growing as countries phase out internal combustion engine vehicles to meet climate targets, and Benchmark Mineral Intelligence now forecasts that graphite will be in supply deficit from 2027.

Today, China dominates the global graphite supply chain and, in December 2023, has introduced export restrictions on battery grade graphite products.

GreenRoc is therefore working to create a secure European supply of coated, purified graphite anode material using graphite from its Amitsoq deposit to support the green transition.

The Amitsoq mine and concentration facility will be located in the south of mining-supportive Greenland, only few days by ship from European ports.

GreenRoc plans to locate an active anode processing plant near a European port with access to abundant CO2-neutral energy and is currently conducting a feasibility study in this regard. The feasibility study is being part funded by a £260.000 grant from the UK Government’s Advanced Propulsion Centre and its outcome will guide GreenRoc’s decision on building a pilot plant during 2024-25.

Chief Executive Officer

As a Danish geologist with over 30 years’ experience in Greenland’s mining sector, Dr. Bernstein brings a very strong knowledge and understanding of the country and its mineral wealth, with his experience spanning both corporate and governmental advisory roles.

Prior to GreenRoc he was the Head of the Mapping and Mineral Resources Department at GEUS, the Danish and Greenlandic Geological Survey responsible for supporting the sustainable exploitation of raw materials in Greenland. In this capacity, he focused on developing Greenland’s known geology through integrated programmes in collaboration with the Ministry of Mineral Resources in Greenland.

Before that, among other roles, he was Exploration Director, and latterly CEO, of Avannaa Resources Ltd, a Greenland-focused mineral exploration company which he co-founded in 2007 and which executed over 25 exploration programmes, discovering the Karrat REE deposit and the Disko Bay diamond province in West Greenland and securing two joint venture agreements with major mining companies Anglo American and Boliden. He has earlier been involved in other deposit discoveries in Greenland, including the Platinova palladium-gold Reef in the Skaergaard Intrusion, stratabound PGE mineralisation at the Kap Edvard Holm Complex, and the Citronen Fjord Pb-Zn deposit.

George Frangeskides
Non-Executive Chairman

Mr Frangeskides has a broad range of experience gained from over 25 years in the mining, legal and corporate advisory sectors in Australia and the United Kingdom and an extensive network of contacts across the mining and investment sectors across the world.

Mr Frangeskides, who is also the Executive Chairman of Alba, initiated Alba’s move into Greenland in 2015 with the farm-in and acquisition of the Amitsoq Project. Subsequently, he led Alba’s strategy of adding other assets to its Greenland portfolio, firstly with the Thule Black Sands Project and then with Melville Bay and Inglefield.

Non-Executive Director

Mr. Panteli is a seasoned finance professional with over 25 years’ experience in the alternative investments industry. He has held a range of senior positions, including at ThomasLloyd Global Asset Management, Bank of America Securities, Dresdner Kleinwort Wasserstein and BNP Paribas Asset Management, and has extensive experience in investment management, research, risk, operations, structuring, allocating capital, due diligence, business development and management.

Mark Austin
Non-Executive Director

Mr Austin, who is Alba’s Chief Operating Officer and Senior Geologist, has significant management and operational experience in a career spanning four decades across a range of commodities. Mr Austin’s experience includes being a Non-Executive Director at Central Rand Gold (2016-2017), being Group Geologist and CEO of Kilimapesa Gold (Kenya) for Goldplat plc (2007-2013), being Vice President Exploration for Mano River Resources plc (2006-2007) and being Senior Exploration Geologist for
Placer Dome Exploration (Africa-Eurasia) Ltd (2005-2006).

Mr Austin was responsible for overseeing the detailed design and planning of the forthcoming drilling programmes at the Amitsoq and TBS Projects.

Lars Brunner
Independent Non-Executive Director

Mr Brünner has been an Environmental Consultant for more than 30 years, during which time he has conducted Environmental
and Social Impact Assessments for a broad range of projects and developed a wide-ranging expertise in environmental matters. From 2014 until May 2020, he was the Arctic Mining and Environment, Business Development Leader for Golder Associates A/S (“Golder”), a leading international mining and environmental consultancy firm, and led the environmental field team at Golder which undertook the first-year environmental baseline studies at the TBS Project in 2018.

Mr Brünner brings with him an in-depth knowledge of Greenlandic law, culture, environment and language, having worked in Greenland for many years. He has established strong relationships with a range of key stakeholders in Greenland and offers invaluable support and advice to the Company’s technical team.

Mark Rachovides
Independent Non-Executive Director

Mr Rachovides is President of the European Association of Mining Industries, Metal Ores & Industrial Minerals (“Euromines”), the recognised representative of the European Metals and Minerals Industry. Euromines’ main objective is to promote the industry and its relations with European institutions at all levels. He is also a Consultant to Dundee Precious Metals Inc.

Mr Rachovides has held numerous board positions in natural resources companies active in Europe and elsewhere over the last twenty years. He was formerly an Executive Director of European Goldfields Limited which was acquired by Eldorado Gold Corporation in 2012. Previously he was Vice President, Europe at Dundee Resources Limited after spending 11 years at the European Bank for Reconstruction and Development (EBRD).

Thule Black Sands,

High-Grade Ilmenite Project on the Coastline of North-West Greenland

GreenRoc’s wholly-owned Thule Black Sands (TBS) Project is a heavy mineral sands project located on the Steensby Land peninsular in north-west Greenland.

The Geological Survey of Denmark and Greenland, GEUS, has estimated that 10 billion tonnes of ilmenite exist in the original rock within the entire Thule region, with a further 7 billion tonnes of ilmenite present in the form of placer ilmenite.

An extensive surface drilling campaign in 2018 led to the declaration of a maiden Mineral Resource for Thule Black Sands.

Extensive follow-up drilling was completed in the summer of 2021, with the aim of substantially increasing and upgrading the existing Mineral Resource at TBS.

Amitsoq Graphite,

An Exceptionally High-Grade Flake Graphite Project in Southern Greenland



 The Amitsoq Graphite Project is located in the Nanortalik region of southern Greenland and is one of the highest-grade graphite deposits in the world, with a total inferred, indicated and measured JORC Resource of 23.05 million tonnes at an average grade of 20.41% Graphitic Carbon, giving a total graphite content of 4.71 Mt. The Resource contains a lower graphite layer that has a JORC resource of 16.88Mt at a grade of 21.51% with 3.634Mt of contained graphite.


Amitsoq and Kalaaq are two of the highest-graded graphite projects in the world.
