                    TITLE 43--PUBLIC LANDS: INTERIOR
 
    CHAPTER II--BUREAU OF LAND MANAGEMENT, DEPARTMENT OF THE INTERIOR
 
PART 3840--NATURE AND CLASSES OF MINING CLAIMS--Table of Contents
 
                        Subpart 3841--Lode Claims
 
Sec. 3841.4-3  Extent of surface ground.

    With regard to the extent of surface ground adjoining a vein or 
lode, and claimed for the convenient working thereof, the Act of May 10, 
1872, provides that the lateral extent of locations of veins or lodes 
made after said date shall in no case exceed 300 feet on each side of 
the middle of the vein at the surface, and that no such surface rights 
shall be limited by any mining regulations to less than 25 feet on each 
side of the middle of the vein at the surface, except where adverse 
rights existing on May 10, 1872, may render such limitation necessary; 
the end lines of such claims to be in all cases parallel to each other. 
Said lateral measurements cannot extend beyond 300 feet on either side 
of the middle of the vein at the surface, or such distance as is allowed 
by local laws. For example: 400 feet cannot be taken on one side and 200 
feet on the other. If, however, 300 feet on each side are allowed, and 
by reason of prior claims but 100 feet can be taken on one side, the 
locator will not be restricted to less than 300 feet on the other side; 
and when the locator does not determine by exploration where the middle 
of the vein at the surface is, his discovery shaft must be assumed to 
mark such point.
