Oliver Frisen, CEO of Guardian Metal Resources, joins to discuss their upsized U.S. IPO and the two tungsten mines they’re looking to create in the U.S. within the next three years. China, Russia, and North Korea make up about 90% of tungsten mining right now. The metal is used for autos, in the aerospace sector, and many other critical areas. He warns that a lot of manufacturing could have to stop due to the lack of the mineral if the U.S. can’t find its own domestic supply quickly.
