Wasn't expecting rise today.

One of the ways I make my money for investing is selling ex-library antique & collectible books.
Low and behold last week I received about 50 years of "Minerals Yearbook" from ranging from 1930''s to early 2000's.
(not a request, I get what I get. Before recycling. A sign maybe).
Was looking at tungsten in US 1945. Mentions the Old Riley mines down the road and the government stock piling after the war.

They (Riley) were pulling 0.62 WO3 back then. Pilot Mountain shows 0.31 WO3.
Is this a feasible project with these grades. I'm assuming processing and retrieval have improved?

Thinking of a visit to Nevada.
