THE KENDALL GOLD MINES
The Kendall mine is located about twenty miles north of Lewistown in the South Moccasin
Mountains. The town is a relic of an old frontier town. lt has only one street and most of the
buildings, formerly a saloon, are closed. The whole town has run down appearance and
probably shows that it has seen better days.
The mine is located at the upper end of the street. lt is not a large mine, and has the camps
elected appearance as the town. lt has two parallel streets, running to depth of about five
hundred feet. Everyone hundred feet a station is dug and from here tunnels, or levels are run in
all directions, alloying the veins of ore. On each level, stopes are dug. These have the
appearance of large vaulted rooms with numerous supports. The men mine upward saving the
ore and letting the waste fill in below.
The ore at first is partly rock and partly powder form and is the color of clay. lt is brought to the
surface, put into cars and hauled to the mill. Here it is run through a crusher, grinding it to a
powderform. lt falls out on the crusher into an endless belt and is carried to the upper part of
the mill. Large vats receive this ore. There are eighteen of these arranged in three tiers, six
tanks in each tier. They are twenty feet in diameter and eight feet high.
To extract the gold from the ore, a weak solution of water and cyanide is made. This is allowed
to soak through the ore in the vats for three days. The cyanide is then drained off, taking a very
large percentage of gold with it.
This method of extracting the gold from the ore is called "The Cyanide Process." lt is used
where low grades of ore, which contain from two to ten dollars worth of gold in each ton, is
mined. lt is a rather recent discovery and is used chiefly in the Transvaal gold mines.
This mixture of cyanide, water and gold is treated with zinc filings. The zinc is placed in
rectangle boxes and the mixture is allowed to run through it. The zinc attracts the gold,
separating it from the cyanide. lt is then treated with sulphuric acid and washed many times to
remove the zinc sulphate. The last process is when it is smelted down into gold bricks worth
S25,000 apiece.
