syenite, like that further north, and the
lodges cut Ii northeast and southwest.
The ledge matter is usually porphyry or
porphyritic quartz. though some lodges OF
pure quartz have recently been discovered.
The principal value IN most cases Is gold
with decreasing silver value as depth Is
attained. but there Is copper in various
forms and often In such high percentages
as 10 make il the principal value. The ore
grows In richness as depth is gained, and.
by sorting. shipments OF high enough
grade to pay well. even under present con-
ditions. could be made from some proper
ties.
The May Earhart Mine.
The mine which gives promise Of be-
coming the first producer is the May Ear
hart group OF three claims. half mile up
Cedar river from the confluence of Bear
creek. the owners being the Robinson Min
ing Company. A prospecting tunnel run
through the cap-rock for eighty-nine feet,
with the ore on the floor, showed an ore
body fully forty feet wide, with no hang
ing wall In sight. A shaft Is down forty
three feet on the footwall. close by the
river bank. and win be extended to a
depth Of sixty feet, TO define the course OF
the ledge. This shows the ledge to have
Strengthened up and 10 carry continually
improving quality OF ore. On and near
the surface the ore was copper and iron
pyrites and gold-bearing hornblend. but as
the shaft was sunk silver and copper
glance and pockets OF bornite began TO
come In, and the mine gives promise OF
great richness. An average of four as

The intention IS. as soon as the strike and
