miles of quartz claims have been located,
and probably more than one third of the
gold product of the county is from claims
struck within two years. Times are better
now in this county than they have been for
number of years, and the prospect for the
future is bright. Prospectors are confident
OF the great mineral resources Of the county,
and for several years to come prospecting
will be continued with unaba,ed zeal
Look TO YOUR BLACK SANp.-The black
sand from placer tailings, sometimes contains
gold (auriterous sulphurets). 1t would be
we'll for miners to ascertain if they have
such sand in their tailings. A mining com
pany at North San Juan, Nevada county, are
saving the black sand having ascerlained
that it contains about half the gold in their
claim. They have now put up pans for
grinding and amalgamating the sand, and
expect to save all the gold.

According to the Flag, this roe assays a
the rate of $4,000 per ton The company
owning this mine have spent upwards o

Empire mill, at this place. has lately added a
number Of the Baux q Guiod pans to the
machinery for saving gold, and within day
or two has made careful experiment to les,
their value. Heretofore they have concen
trated the sulphurets and sold them to be

weighing 2,7O0 pounds; and after saving the
gold by the usual process, the taiIings were
run through the pans instead of separating
the suphorets. The amalgam cleaned up in
the pans amounted to fifty two ounces, which
retorted $685. 1t is estimated that the tail.
