US coking coal producer and rare earth developer Ramaco Resources has signed a non-binding memorandum of understanding (MOU) to potentially supply gallium (Ga) and germanium (Ge) to US-based metals refiner and manufacturer Indium Corporation.
Ramaco's supply would come from its Brook Mine project in Wyoming, which the company broke ground on in July of last year.
The project is set to begin production in 2027, followed by two years of optimization before reaching full steady-state operation, the company previously said.
The deposit contains 40pc primary magnetic rare earth elements oxides — neodymium, praseodymium, dysprosium, and terbium — as well as three critical minerals: gallium, scandium, and germanium.
Ramaco announced plans in October to establish a stockpile of rare earth elements and critical minerals at the project site.
Indium Corporation refines metals and manufactures materials, including gallium and germanium-based products, for the semiconductor and electronics markets, among others.
