Ramaco Resources and Indium Corporation have entered into a non-binding memorandum of understanding covering the potential supply of gallium and germanium from Ramaco’s Brook Mine rare earth and critical-mineral project in Wyoming. The gallium and germanium supply deal outlines a proposed relationship between a domestic mining operation and an established downstream materials manufacturer, linking US mineral production with advanced-technology supply chains.
Under the terms of the MOU, the two companies agreed to negotiate the potential supply of gallium and germanium from the Brook Mine project. The agreement is non-binding, and no confirmed volumes, pricing or long-term purchase commitments have been disclosed. The gallium and germanium supply deal represents an early-stage exploration of a commercial supply arrangement rather than a finalised contract.
Ramaco and Indium Agree Gallium and Germanium Supply MOU
Ramaco Resources is developing critical minerals and rare earth elements at Brook Mine, located near Sheridan, Wyoming. The company describes the project as holding what it believes is the nation’s largest unconventional deposit of rare earth elements and critical minerals sourced from coal and carbonaceous ore. Ramaco says Brook Mine is America’s first new rare earth element and critical-mineral mine in more than 70 years.
Full-scale mining is underway at the site, and construction of a pilot processing facility is also in progress. The project is initially focused on the vertically integrated production of commercial oxides.
Ramaco Resources CEO Randall Atkins said the gallium and germanium supply deal demonstrates a promising opportunity to introduce Brook Mine gallium and germanium into established domestic and allied supply chains. “By combining Ramaco’s potential domestic resource base with Indium Corporation’s established presence in advanced technology manufacturing, we believe this proposed relationship could strengthen and diversify the supply of materials that are increasingly critical to the U.S. electronics, semiconductor, and advanced manufacturing industries,” Atkins said.
Brook Mine Advances Critical Mineral Development
Brook Mine sits at the centre of Ramaco Resources’ broader critical minerals strategy. The project’s location near Sheridan, Wyoming, positions it within established mining territory, and the company is building out processing infrastructure alongside its mining operations.
The focus on vertically integrated production of commercial oxides is intended to move the project beyond raw extraction and into processed materials that can feed directly into downstream manufacturing. Gallium and germanium are two of the critical minerals targeted for production at the site.
Deal Links Mining With Advanced Manufacturing Supply Chains
Indium Corporation, headquartered in Clinton, New York, is a global materials refiner, smelter and manufacturer. The company supplies specialised metals, solders and thermal management products used in building electronics, semiconductors, electric vehicles, aerospace and defence systems. Indium specialises in refining, alloy development and manufacture of high-performance materials, including gallium- and germanium-based products used throughout the semiconductor value chain.
The proposed gallium and germanium supply deal between Ramaco Resources and Indium Corporation would connect domestic mineral production at Brook Mine with Indium’s downstream manufacturing capabilities. If the companies reach a binding agreement, it could provide a US-based source of gallium and germanium for products that currently depend heavily on imported materials.
The MOU underscores growing interest in establishing domestic critical-mineral supply chains that link mining operations with advanced manufacturing within the United States and allied nations.
