Sweeping Of Tonopah Sands

This is known locally sweeping the tsings and several
local people engaged in this and profitable occupation
which first into vogue Tonopah of 1912
The history of the origin Of this industry is rather interesting
In the 1909 James Carter who opening small
pect the Gold Roads Arizona accidentally
that thin crust which had formed the Of the tang Dump
carried considerable vues and obtained
that then operating the property and after months
eraons realized such large profits that the purchased
lease for considerable the directors believing
good policy to allow dump ease obtain such excellent results
from the angs might lead the conclusion that the values
in the ore were not being properly saved
One of the working in this mill investigated the
very carefully and found the condition angs
pond Of the Tom Reed mne miles distant but failing
lease there Tonopah and secured the sngs
the mine and proceeded sweep these with
satisfactory results.
The taings Tonopah in three separate
from the Montana End, Tonopah
MacNamara mills for distance of nearly five miles the
where they pond and from the Belmont mill
the east and all of these pon within reasonable distance
from the mills thin the surface which, being
carefully examined found to excellent values
large number of leases have been granted royalty and
operation and the sweepgs frequently give returns from
$50 to $50 a ton.
The condition rather curious when remembered that the
average values Of the med Tonopah about $18
and the meaurgca losses only from 80 cents 81 ton
Hence 1t is at first difficult understand why the sweeping OF
these angs should yield such very high values The explanation
be that the values contained in the cyanide
small escapes when
aings discharged from the MILL This solution becomes
cenated in the tang tangs dry and cracks
formed in them by the heat of the the solution drawn the
surface and spread thin crust small por
on of the bed and easily recognized it's dark color showing
that silver uphdes This crust frequently not
thick and carefully swept gathered
has been discovered that by culvatng
bed the field grain cultivated the action
of the produces recurring crops
Of these tangs have become quite expert in
down the guhes have dug channels for the
the mills built dams and spread the angs over
ground enable the to get better
ton rpon the solutions
that any values could the low val
ues of the tangs discharged from the mills but all
royalty to the company owning
the land on which the tailngs ponds are situated
Several hundred these sands have already been shipped
ont Of the camp from the tangs formed from all the mills in the
camp and as the output mills is we'll maintained the
reoaded as "hardy which will fail long the
Tonopah mills in operation
An interesting point stated in connection with this industry is
that it is only profitable egnding asmng plant is
in operation
It notable that valuable leases situated nearest
the discharge end OF the mills
Other leases are now operation at Mlers the taling
ponds from the Tonopah Mining Company and the old Belmont
mill and these are also producing good results
The sands when shipped to the smeers at Salt
which make an inclusive charge for freight and treatment of
values excess OF soo on gooo ponS
made the royalty has been paid to the company
