This is the name of the principal mine in the district. It was located
and worked many years since by Mexicans, but has during the past eight
or ten years been in the hands of Americans. The vein strikes northwest
and southeast, dipping to the southwest at an angle of 50° from the
horizon. The rock is a white, fine-grained, saccharoidal quartz, showing
in places bluish bands. It contains free gold in variable amount, with
some iron sulphuret. A very large amount of quartz has been stoped from
the vein and crushed in various mills.
The Red Rover is quite extensively developed, the new vertical shaft
being down over 400 feet. The old inclined shaft, which is sunk on the
vein, is down 220 feet. Several levels are run out from both these
shafts, which are 200 feet apart. The new shaft was sunk between the
main vein and a spur which branches from it. A crosscut was run out
toward the spur, which is opened on the surface, but it was found it did
not go down. A crosscut was then run toward the main vein, which was
found intact, and a drift was carried in 60 feet on the vein.
The country rock is mostly massive metamorphic, very much broken and
faulted. Nearly every mine in the district has been displaced more or
less by these faults. For some reason the Red Rover has been shut down
for some months past. It is understood that operations are to be
resumed.
