CHARACTER OF THE ORE The
q hubnerte occurs in the white q artz in
various sized crystals. many OF which
are 3 inches long and plainly show the
crystalline character. Massive speci-
mems when broken show cleavage planes
from TO four inches loag and / To
inches wide. However much of The
mineral Is IN fine grains and IN irrcgu-
lar bodies. The quartz j. found entire.

era-. besides the hubneriie. scheelte
and quartz, were the only ones found,
unless more careful examination dis
closes the presence of woiiramite mXed
with the hubnerite.
Practically all the ore shipped has
been either hand sorted and c0bbed or
concentrated by the crude methods
outlined above These ores carried an
average of 6s per cent tungstic acid.
One shipment of 1000 pounds gave 60o
pounds of 50 per cent concentrates The
ore was closely tobbed before shipment,

From the ore as exposed in the crop

the opinion OF the writer that the
whole vein matter, IL carefully concen-
trated so as to save both the hubnerlte
Nd the scheelite, would produce 10 per
