Constantine Karayannopoulos has joined Greenland Mines’ newly established Strategic Advisory Board, giving the former Neo Performance Materials CEO and upcoming Atlanta conference speaker a formal role advising a company with two flagship projects in Greenland.
Greenland Mines announced the appointment on September 14. The board will support development of the Sarfartoq neodymium and praseodymium rare earth project in southwest Greenland and the Skaergaard palladium, platinum and gold project in southeast Greenland.
Karayannopoulos joins Thomas Abraham-James and Bent Olsvig Jensen. Abraham-James worked directly on Skaergaard during three Greenland field seasons between 2008 and 2010, while Jensen brings extensive experience in Greenlandic mining, logistics, permitting and stakeholder engagement.
The company said Karayannopoulos will advise on rare earth strategy, mineral processing, product development, market positioning, potential offtake agreements and partnerships. His work will also cover government engagement and relationships across North American and European critical mineral supply chains.
Karayannopoulos led Neo when the company pursued and later acquired the Greenland company holding Sarfartoq’s exploration license. Under his leadership, Neo positioned the deposit as a potential source of rare earth feedstock for its European operations.
Greenland Mines completed its $35 million acquisition of the Sarfartoq license holder on September 1, following approval from the Government of Greenland.
The appointment comes shortly before Karayannopoulos is scheduled to make two appearances at the Critical Minerals Expo North America in Atlanta.
He will participate in an October 28 discussion titled “Expert Overview of North America’s Critical Minerals Supply Chain: Where Are We Going?” On October 29, he will join the panel “America’s Race for Rare Earths and China’s November Reckoning,” examining American supply chain vulnerability ahead of two approaching Chinese export control deadlines.
A second September 14 announcement adds industrial context to Sarfartoq’s potential supply chain role. Neo said its rare earth magnet plant in Narva, Estonia, has entered commercial production and delivered its first sintered magnets to an electric vehicle motor customer.
