Comments

Comment (Deposit): Deposit consists of reworked residuum derived from underlying ophiolite complex and Swauk Formation

Comment (Geology): Ingalls Complex is an accreted ophiolite terrane

Comment (Workings): Adit and several open cuts

Comment (Reserve-Resource): Broughton (1943, p. 16-19) reports 59,850 tons of exposed, 45,720 tons of probable, and 435,850 tons of possible resources.

Comment (Geology): Some of the laterites were reworked prior to deposition of the Eocen Swauk Formation. Lamey (1950, p.) tentatively
