$METCB Falls 3.6% After Gallium/Germanium MOU
Ramaco Resources (NASDAQ: METC, METCB) said it signed a non-binding memorandum of understanding with Indium Corporation tied to potential gallium and germanium supply from its Brook Mine project — and $METCB fell 3.6% on Aug 18, 2026.
What Ramaco announced
Ramaco said it entered into a non-binding MOU with Indium Corporation relating to the supply of gallium and germanium from Ramaco’s exploratory Brook Mine rare earth and critical-mineral project in Wyoming.
Indium Corporation is described as a global leader in advanced electronic materials and specialty metals, serving end markets like semiconductors, electronics, aerospace, defense, and advanced manufacturing. The company’s capabilities include refining, purification, alloy development, and manufacturing of high-performance materials, including gallium- and germanium-based products used across the semiconductor value chain.
Under the MOU, the two companies agreed to negotiate the potential supply of gallium and germanium from the Brook Mine project. Ramaco emphasized the MOU is non-binding, and any future supply or offtake arrangement would depend on due diligence and the negotiation and execution of definitive agreements.
What it means for Ramaco
In plain English, this is an early-stage “let’s work toward a deal” document — not a firm contract. Still, it could help Ramaco frame Brook Mine as more than an exploration story by linking the project to a potential downstream customer conversation.
If talks progress, a supply relationship with a specialty-metals player like Indium could support the case that Brook Mine’s gallium and germanium outputs may fit real-world industrial demand, particularly in semiconductor-related applications mentioned in the announcement.
But because the MOU is explicitly non-binding, the near-term business impact is uncertain. Any meaningful change would likely hinge on what comes out of due diligence and whether the parties ultimately sign definitive agreements.
