important subject, 1t will no doubt be
interesting to mining men in general
and more particularly TO those Operat.
Ing placer groundf:
| The question of closer concentration
| of the silver.lead ores of the South
| Fork 10 one that has been seriously
considered by mine owners'ever since
| the first mill was erected, and 1t is still
| as serious as ever. Millions OF dollars
| worth Of lead and silver have already
gone down the South FORK, and In
spite OF vast improvements tens OF
thousands more go every month.
Probably no mine in the world has
| produced 40 much wealth dur
lug the same time as the
Tiger-Poorman, Hecla, Black Bear,
Helena and Frisco, STANDARD, U Mon,
Milwaukee and Granite have dumped
into Canyon creek along with their
tailiuge. With the crude machinery
OF early days the tailings would some
times assay as high as 20 per cent lead,
with corresponding amount of silver.
Such tailings had they been saved In
some way, as some of the mines around
Murray are doing, would pay hand
somely for remilling.
With Improvements In machinery
and methods and the addition of de-
Vices making a more complies plant,
the per cent lost has beer gradually
lowered until in exceptional cases the
tailings have only yielded ~ per cent
of lead, although the average from
even the best mills is considerably
higher than this. Closer milling can be
done and q larger per cent saved,
but 1t necessitstes the addition OF too
much waste to the concentrates, the
freight and smelter charges on the
waste amounting to more than the
value OF the additional metal saved.
In early days when lead was worth
twice as much as now, aud silver so

borne by mine owners-although 1t
was far from agreeable even thsn-but
