Of the surface inclosure, and of “all veins, lodes, and ledges which lie under the top or apex of such lines, extended downward vertically,” even though they in their descent extend outside the “side-lines of such surface locations.” The right to such outside parts of veins or ledges is confined to all that lies between “vertical planes drawn downward,” as described, so continued that these planes “will intersect” the exterior parts of the said “veins or ledges.” The surface of another’s claim cannot be entered by the locator or possessor of such lode or vein. What Constitutes a Deposit. The word “deposit” has always been construed by the Land Office to be a general term, embracing veins, lodes, ledges, placers, and all other forms in which the valuable metals have ever been discovered. Whatever is recognized as a mineral by standard authorities, where the same is found in quality and quantity sufficient to render the land sought to be patented more valuable on this account than for purposes of agriculture, is treated by the Land Office as coming within the meaning of the act. Lands, therefore, valuable on account of borax, carbonate of soda, nitrate of soda, sulphur, alum, and asphalt, it is held may be patented. The first section of the Act of 1872 says, “all valuable mineral deposits.” The sixth section uses the term “valuable deposits.” Deposits of fire-clay may be patented under the act, and so may iron deposits, which may be patented as vein or placer claims. Lands, more valuable on account of deposits of limestone, marble, kaoline, and mica than for purposes of agriculture, may be patented as mineral lands. Miners’ Form of Notice.
