Search 30 U.S.C. § 23 : US Code - Section 23: Length of claims on veins or lodes

Mining claims upon veins or lodes of quartz or other rock in
place bearing gold, silver, cinnabar, lead, tin, copper, or other
valuable deposits, located prior to May 10, 1872, shall be governed
as to length along the vein or lode by the customs, regulations,
and laws in force at the date of their location. A mining claim
located after the 10th day of May 1872, whether located by one or
more persons, may equal, but shall not exceed, one thousand five
hundred feet in length along the vein or lode; but no location of a
mining claim shall be made until the discovery of the vein or lode
within the limits of the claim located. No claim shall extend more
than three hundred feet on each side of the middle of the vein at
the surface, nor shall any claim be limited by any mining
regulation to less than twenty-five feet on each side of the middle
of the vein at the surface, except where adverse rights existing on
the 10th day of May 1872 render such limitation necessary. The end
lines of each claim shall be parallel to each other.
