Koonts. president ana general mana ger
of the Manhattan Big Four, has stated
10 your correspondent In an interview
that the company has just completed tho
instaila tiou OF An electrically driven, tri-
pley, Could station pump, with hoist
ing capacity OF 500. .000 gallons daily
against 7o0-foot head This pump has
been installed Just above the large sta :
ton on the 50o-fool leve;. in order that
the drifts and crosscuts on this level may
constitute i reservoir In the event oi
power interruption or the disabling OF
the pump temporarily from any other
cause,
Machinery for mill Of $50 tons daily
| capacity. EMPLOYING tho amalea mating
process, has been ordered from tne
Joshua. HenGy iron works OF San Fran-
cisco. The plans for the' mill have peeh
submitted and approved and ihe com
pauy will make every effort To have the
plant in full operation before tho end OF
the current year. An abundance OF va :
ter will be avsilab bic at an times, the
mill will be erected on An admlranIe Ia
gravity site and little grading VIII be re-
ouired to prepare fer its erection
Low Cost Estimated.
The compsny's engineers and mill eS-
perts are convinced that with the com.
bina ton OF free milling ore, tho present
advanced stage Of development and an
ample supply OF water direct from the
mine the total cost OF mining ana mil
Ing, eTecting a recovery OF % to 96 per
cent, Will not exceed 80 per ton. =,
With the mill in operation tue ore VII

each, and to the l5o-mesh. then over

each stamp Will have q crushing capacity
OF fifteen tons daily.
The equipment now in use, All oIeT-
s.ted by electricity, includes t"elye-
