NEW YORK — US Tungsten Corp. has named Michael Olsher its chief executive officer, as the company continues to search for a domestic tungsten source.

Olsher will replace Matthew Markin, who had served as interim chief executive officer.

Olsher comes to the position having worked as a self-employed raw materials consultant for MetMin Trade and Finance LLC since 2010. He has also worked as a division head for companies including Considar Inc. which is now part of Traxys Inc.).

US Tungsten is focused on finding a domestic tungsten source “through aggressive prospecting and staking across the western United States”, the Henderson, Nev.-based company said.

In October, US Tungsten acquired property near the site of a former tungsten mine in southwestern Montana, in what Olsher said “will hopefully be the United States’ first tungsten mine in some several decades.”
