Mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "Strategic Minerals Guide for Oregon Prospectors". Unavailable since 1942, this publication offers rare insights into how to identify critical and strategic mineral deposits that are known to exist in the State of Oregon. The guide particularly focuses on aluminum, antimony, chromium, manganese, nickel, quicksilver, tin, tungsten, platinum, titanium, vanadium, cadmium, magnesium, copper, lead, zinc and others.
