SIGNIFICANCE OF WORK,


SIGNIFICANCE OF WORK.
The significance of this work is
best shown by the geology of the
camp. The early mining in Phoebe
was along the north side of a range
Of mountains which run in a north
westerly and southeasterly direc-
ton. On the north side of this
range, owing to faulting and erosion,
the quartzite is exposed. In this the
| famous assures In the early '70s pro-
duced high-grade silver-gold-lead
ore which yielded $40, 100000. The
ore was oxidized and the chief silver
values were in the chlorides and
/ bromides.
Along each side of this range Of
mountains there is series of fissur-
ing which runs more or less parallel
with the range. On the north side
it is believed that the famous Yuba
dixie, an intrusive porphyry, has
been the mineralizing agent. On
this side there is only small por-
ton of lime exposed, erosion having
taken place down to the quartzite
In the one place where the lime
shows on this side the assures ap-
parently have not cut through it.
The Prince mine is located across
the ridge, mile and a half south
west of Phoebe. Here there is lime
and shale series everything the
quartZite and the fissures have cut
through this to the surface, showing
that the fracturing was stronger on
this side. The exploration of these
assures to the quartzite has attraet-
ed attention in this section of the
camp for years
