PAY SHOOTS AND LODE STRUCTURE. 
All of the ore in the Anchoria-Leland mine except that in the City View dike 
occurred in typical narrow sheeted zones in breccia. The maximum width of the 
ore appears to have been about 5 feet. In places the sheeted structure is remarkably 
well developed, the rock having been fissured for a total width of a foot or more into 
thin plates a fraction of an inch in thickness. On each side such close sheeting 
passes through more widely spaced Assuring into the ordinary country rock. Such 
highly developed sheeting may be seen in the Chance and Wardel lodes on level 4, 
and less conspicuously in the Matoa lode. The fissures are often fdled or partly 
filled with quartz or quartz and fluorite. In spite of the great regularity exhibited

for short distances by these sheeted zones, they are not as a whole notably persistent. 
They sometimes dwindle to a single indistinct fissure or come to an end upon 
meeting another fissure zone of somewhat different strike and dip. This is well 
illustrated by that part of the Matoa lode within the Anchoria-Leland ground. The 
ore in this lode, as shown in the abandoned stopes, changed repeatedly from one set 
of fissures to another set of divergent dip or strike. 
The most striking fact in connection with the Anchoria-Leland mine is the 
comparatively slight depth to which the ores extended. The Chance lode has, so far 
as known, no ore below level 2, and very little ore below level 1. Practically all the 
ore, in other words, was within 300 feet of the surface. Furthermore, the five or six
