Tombstone Mexico owns Tres Marias zinc-lead-germanium project in Chihuahua, Mexico.

War Eagle president and CEO Thomas Atkins said Tres Marias is a unique deposit in which exploration to date has defined a resource that is unlikely to be able to be developed as a stand-alone operation.

"The transaction with COMSA enables the development of the mineral resource at Tres Marias such that shareholders of War Eagle can realize a return from the prior investment in the property.

"COMSA intends to mobilize mobile equipment that should enable the mining and processing of the mineral resource at Tres Marias to the mutual benefit of both COMSA and War Eagle," Atkins added.
