Key Takeaways
Three states hold two-thirds of U.S. tungsten. Nevada (55),
Colorado (38) and California (27) account for 66% of all
183 mapped features.
Pine Creek is the giant. California's Pine Creek mine delivered
60,125 t W between 1918 and 1990 — 41% of all reported
U.S. mine production.
Resources dwarf production. Reported resources total
817,549 t W — more than 5× recorded output — led by the
Andrew Curtis deposit (215,000 t, Inferred).
