PAY SHOOTS AND LODE STRUCTURE. 
The Cobb, the principal lode in the Moon-Anchor mine, is a zone of Assuring 
along a phonolite dike, the latter being usually less than 2 feet wide. On level 4 
of the Moon-Anchor, which is about 35 feet above level 6 of the Midget, the Cobb 
lode has been sloped for about 200 feet, these stopes being continuous with those 
on the Midget lode. The Midget and Cobb ore bodies are thus in reality parts of 
a single pay shoot, although, as already pointed out, the Cobb phonolite dike, 
accompanied by some Assuring and mineralization, is probably what is known as 
the Intermediate vein in the Midget mine. (See Ag. 28, p. 299.) The Midget- 
Cobb pay shoot pitches northeast at an angle of about 45°. At a depth of about 
400 feet it crosses the provisional or “compromise” line from the Midget into the 
Moon-Anchor ground and at the same time changes from the Midget Assure zone 
with southeasterly dip to the Cobb Assure zone with northwesterly dip. Just 
what takes place at the point of change is difficult to determine in the present state 
of the workings. It is certain that a number of other Assures, including the Lead 
vein, converge toward the debatable ground where the Midget, Cobb, and Inter¬ 
national lodes come together. On the lower levels of the Moon-Anchor the Cobb 
pay shoot is shorter and is usually conAned to the intersection of the Lead and 
Cobb lodes. The ore in such case occurs in the sheeted breccia on one or both 
sides of the sphalerite and galena streak of the Lead vein. The latter, so far as 
known, contains no workable ore. The only ore thus far stoped from the Inter¬ 
mediate lode in the Midget mine occurs just above level 6, northwest of the shaft. 
In the Murray lode, which is the continuation of the Midget lode south of the 
Bonanza King lode, some small pay shoots have been worked just above level 6 of 
the Midget. 
In the Bonanza King lode the ore occurs in two rather irregular pay shoots, 
one mainly in the breccia and one mainly in the gneiss. The ore in the breccia 
lies chieAy to the east of the Midget or Murray lode and has been stoped from the 
surface to level 6. Its maximum length is about 350 feet, but it includes some 
portions of the lode too low in grade to work and might be considered as made up 
of two or more separate pay shoots. 
The western pay shoot, in gneiss, is more compact and irregular. It has been 
stoped from a point above level 5 to level 7, and ore is known also on level 8. This 
pay shoot pitches about 60° SW. and attains its greatest length, 250 feet, near 
level 6. The gneiss along the course of the lode is traversed by numerous small 
irregular Assures which contain the ore. The stopes are occasionally 15 or 20 feet 
wide. In the western part of the workings, near the Protection and Mariposa 
shafts, the Bonanza King lode is crossed by some small Assures striking north- 
northeast. The gneiss in the vicinity of these interstices is traversed by numerous 
small irregular fractures containing pyrite and calaverite, with quartz and Auorite. 
This ore is being stoped between the Midget level 5 and the surface. It forms 
irregular bodies at the intersections of the more prominent Assures and is partly 
oxidized. 
The main pay shoot of the Conundrum lode lies partly in the Midget mine and 
partly in the Conundrum. The pay^ shoot begins near level 1 of the Conundrum
