“Mineral Lands” as used in Rev. St. U.S. section 2302

[Assembler]

Below is some information about "Mineral Lands":

The term “Mineral Lands” as used in Rev. St. U.S. section 2302 is one of broader significance than “Known Mines”. It refers to a class of lands, rather than specific tracts easily ascertainable, not only by the Land Department, but by the applicants themselves. Old Dominion Copper Mining and Smelting Co. v. Haverly, 90 Pac. 333, 338, 11 Ariz. 241.

"Values"

It appears that "Blocking out ore" and doing enough "Fire Assaying tests with or without Amalgamation and Chlorination tests" is one way of proving "actual production values".
Some of the actual steps are in "Manual of Assaying by Alfred Stanley Miller, Professor of Mining and Metallurgy, University of Idaho". This one just bought a 1905 copy. Way over this one head however gives a good idea thereof values per ton.
