MINES BETWEEN ALTMAN AND GOLDFIELD.

pear entirely away from the strong vein systems. The ore is sometimes shipped 
as broken, but often it is found more advantageous to screen it; its grade is low 
compared with some other mines like the Vindicator, averaging between $20 and 
$25. On the other hand, the tonnage is considerable. 
ORE SHOOTS. 
The ore shoots of the Golden Cycle are not more than a few hundred feet long; 
they are either vertical or pitch steeply northward, as, indeed, seems to be the rule 
throughout this part of the district. No cross fissures are present and no structural 
conditions seem to influence the ore shoots, except possibly spurs and branches 
which sometimes have an enriching effect. On the Harrison vein, with the Anna 
spur, a good ore shoot, 10 feet wide in places, went to the surface and was also stoped 
on the tunnel level. On levels 3 and 4 it lengthened to 500 feet and the Anna 
spur proved very productive. Lower down it decreased in length to 300 feet on 
level 7. On levels 8 and 9 the vein is of low grade; it here appears as a narrow 
sheeted zone with a central clay seam from which values of $10 may be obtained. 
The most productive vein is the Legal Tender. Its shoot is said to have been 
poor and short on the highest levels, though it has been stoped on these in Theresa 
ground. The shoot has a decided northward pitch. On level 3 the shoot is 250 
feet long and lies on both sides of the shaft. On level 6 it increases its length to 
400 feet. On level 8 the shoot extends 300 feet northwest from the shaft and has 
been very rich, while the vein breaks up southeast of the pay shoot. Finally, on 
level 9 the shoot is 400 feet long and values are maintained. In the deepest level 
the Legal Tender vein shows 7 to 10 feet wide with entirely oxidized seams in fresh 
pyritic breccia. In stopes between levels 8 and 9 the payable portion is 6 feet 
wide, without well-defined walls. The rock is a fresh breccia cut by a central seam 
and many smaller ones, all brown and oxidized. The Theresa East vein first appears 
on level 7, 35 feet east of the Legal Tender, and much ore was stoped on it between 
levels 7 and 8. On level 8 it dips 60° SW. and joins the Legal Tender 30 feet above 
level 9. The ore extracted from a single raise from level 9 to 8 near the Theresa 
boundary line is said to have yielded $25,000. The vein is 5 feet wide, and shows 
oxidized seams. Screenings often yield 6 ounces per ton. The Middle vein shows 
a good ore shoot on level 8, with a very rich central seam, sometimes containing 
200 ounces per ton. 
An important ore shoot has been mined on the Revenue vein from the surface; 
it is 200 feet long on the tunnel level and 10 feet wide in places. These large stopes 
continue through succeeding levels from 3 to 8, inclusive, and show at least one im¬ 
portant spur vein. 
On the La Bella vein shorter stopes connecting with the Christmas mine were 
carried to the surface from the tunnel level, while on level 3 the vein was small and 
the ore body short. On levels 4 and 5 the shoot was much better and up to 150 
feet long. Ore continues on this vein down to level 9, the deepest yet opened. The 
vein here shows a small central seam carrying a little calaverite, but mostly oxidized. 
Little fluorite is present. The screenings from a width of 3 or 4 feet contain 
about 2 ounces per ton.
