$WFEMFTungsten is on Warren Buffett's list. It's no secret that he considers it more valuable then gold. Tungsten is a valuable rare earth critical resource. I think Warren Buffett wants to protect himself and Berkshire Hathaway from the $85 billion dollars per month in new currency printing by the United States Federal Reserve. Which explains why Buffett's company IMC a Berkshire Hathaway subsidiary is interested in the Woulfe Mining tungsten assets.
