reopened in 1899. The ore is chiefly galena, with some tetrahedrite, 
the latter being more abundant in the upper tunnel. There is no 
mill at this mine, and the ore was formerly packed out on burros. 
Titusville mine, at the head of Kendall Gulch, although not in Sil- 
ver Lake Basin, may be most appropriately mentioned here as being on 
the same great lode as the Buckeye. This mine was first worked about 
1880. A small mill was subsequently erected in Kendall Gulch, and 
the ore was carried down on a lightly constructed Huson tramway 
about 8,000 feet in length. The mine ceased operating in 1893. It 
was developed on four levels, aggregating about 1,150 feet of drifts. 
The lode is about 30 feet wide. lis general dip is to the northeast at 
about 80°, although ii is locally vertical. It consists of chalcopyrite, 
galena, sphalerite, and pyrite, in a gangue of quartz and rhodochro- 
site. Chalcopyrite is the most abundant ore mineral. The ore is gen- 
erally of low grade, that containing abundant chalcopyrite running 
about $6 per ton. There is a richer streak, however, usually about 14 
inches wide, which may run as high as $30 per ton. Some of this 
richer ore contains very finely crystalline galena scattered through 
the quartz in minute particles. Where this occurs the ore may carry 
from 1 to 3 ounces of gold and CO to 100 ounces of silver per ton, 
the value being associated with the presence of the galena. The 
product of the Titusville mine in L888 was $51,300. 
From this mine the lode can be traced over the slope to the summit 
of Kendall .Mountain, where it appears to divide. It has been pros- 
pected along this distance on the Seymour, Emma, Pyramid, Pompeii, 
and Sal Custer claims, and some ore has been taken out, chiefly 
galena. On the west slope of Kendall Mountain, the Idaho prospect, 
in Silverton Gulch, is apparently on the same fissure or fissure zone, 
although it is here very different in character. The country rock at 
this point is monzonite, part of the great stock of Sultan Mountain. 
The vein liere is usually without gouge and narrow 7 — 18 inches or less. 
It dips southwesterly about 80°. The ore is mostly chalcopyrite and 
pyrite, with pockets of galena in a quartz gangue. The galena usu- 
ally occurs in the middle of the vein, with quartz, chalcopyrite, and 
pyrite on the sides. This prospect has been worked intermittently 
for twenty years and has produced some ore. The development con- 
sists of two tunnels and some small stopes. 
LODES OF HAZELTON MOUNTAIN. 
General. — Hazelton Mountain, as the spur separating Blair and 
Arrastra gulches is called, was the scene of some of the earliest min- 
ing in the quadrangle. In 1874 work was already in progress on the 
Aspen, Prospector, Susquehanna, Mammoth, and other claims, most of 
which were afterwards consolidated as the Aspen mine. 
Aspen mine. — The workings of this mine, which are extensive, are 
shown in plan and longitudinal section in fig. 12. As early as 1875,
