Particular Attention Has Been Given to
the Gold Mines of Amador
County.
NEUTRALITY-SUSPICIOUS. MINE.

WlLOMAN-M
This is at Suffer Greek. The prop:
erty consists of the Wildmau, Mahoney
or Hector, and Stewart claims, also the
Waechter ranch to the eastward OF
these mines on which new vertical
shaft is being sunk. The development
at present is chiefly confined to the
Wildman and Mahoney claims, which
join and are operated through two in
clined shafts. The Wildman is 1900
feet deep, the MahOney 1000. The 1000
foot level of the MahOney is equivalent
to the 80O-foot level Of the Wildman.
The ore bodies of these mines, both
great and small, appear to be confined
to definite zone lying between two
reefs of Mariposa clay states, although |
these latter appear not to he directly
associated with the ore-bodies them
selves. The zone included between
the clay states consists principally of |
amphibolite schist and tufaceous black |
states. In the southern portion OF the |
Wildman Mine the ore zone is confined |
to narrow limits, but going northward |
it broadens and in the Mahoney claim
the vein splits into two sections, the
east branch going into The Stewart
claim and the west into the Lincoln. |
The idea seems to prevail that the |
mines of the Gold Belt of Amador
County are simple assures. which are
easily followed and are regular and per-
sistent. Just the reverse, however, is
usually the case, a. the ore bodies are
found distributed by faults, and often
cOntorted and displaced in most puZ
zling manuer On the 300-foOt level of
the Mahoney Mine one vein follows a |
gouge feet wide, on the hangingwall |
OF which the ore continues for dis |
lance o. 300 feet; going southwark for
some distance the ore loses its value, |
but undergoes no physical change that
is noteworthy. Noticing that the
gouge contained small masses of good |
ore, from 20 to 400 pounds in weight,
Superin tendent Ross cross-cut into the
IOOG-WdH SOOu OiO III bnC
opposite side This was the only place
known, up to that time, where pay ore1
was found in the gouge. The ore
found on the foot-wall side of the zone
was Is feet wide, but its length has not
been determined. These ore-shoots
are known to overlap % feet at least,
and probably much more. Another
instance of irregularity was noticed in
the Mahoney Mine 80 feet above the
900-foot level, where Is found what ap-
pears to be displacement of banded
vein Is feet in width, which, together
with the inclosed states, is contorted
and cut off abruptly, the sheared end
AUDITING against solid vein Of quartz
20 feet in thickness. The continuation |
of this faulted vein has not, as yet, been
found above. The slaty material found
underneath the banded vein is also
gold bearing in paying quantities. A
stope on the 900-foot level of the
Mahoney follows a well-defned per-
sisteut wall for long distance. This
stope is % feet in width. A assure
crosses the ore-shoot at an angle of IS
degrees, dipping south. Beyond this
was found the above described disturb
ance. On the 10O0-foot level of this
mine, a stope follows what appears to
be the wall above described, with large
ore deposits on either side of the wall.
The wall takes slight fexure to the
west, and the ore follows the wall on
the foot side, while that previously fol-
lowed on the hanging-wall side bears
more to the east, and slate horse
separates them. In the main level,
the drift continues south, and new
ore-shoot comes in from the east or
hanging-wall. A diamond-drill hole
runs west, here passes through 6 feet
of slate and cuts 3 feet of quartz, which
is succeeded by % feet of slate and 6
feet Of ore. This probably represents
the two branches of the divided vein.
