northeast of the town of Gold Hill, south of the main road from Boulder to Gold
Hill, and at the western edge of Horefal Flat. Zhe altitude of the millsite is
between 8,575 and 8,590 feet, with the Cash mine shaft at 8,200 feet, and the
Who Do mine shaft at 8,190 feet elevation. Access to the property can be
gained by two private roads, which traverse the area south of County Road No.
52 (see Map A).
Since one of the principle purposes of concentration is to reduce the espenee of
delivering a mine's product tq a smelter, this concentrating mill is situated as
close as is practicable to the source of rte ore supply. 'The proposed gravity and
flotation concentration mill is constructed approximately one-fourth of a mile
from the Cash and Who Do mines (see Map A). Water for the mill will be
drawn from Left Hand Creek, and pumped up a pipeline in Aikens (Lick Skillet)
Gulch to the millsite, where it is stored in underground mine workings. 'Three
phase power for the milling facility is obtained from the Public Service Com-
pany of Colorado, which extends this power another 640 feet along an existing
line, and installed 3 transformers near the southwest comer of the proposed
mill building.
Perhaps the major reason for the final selection of the Horafal Flat site, was its
suitability for the safe, efficient, and environmentally acceptable disposition of
the tailings that result fi•cm the milling process. Other mountain sites that
were examined did not afford the opportunity to construct a hillside tailings
structure, with a limited upstream drainage area. Finally, constructing a tail-
ings embankment northeast of the proposed mill building had less visual effect
on the landscape than any of the other possible mountain sites.
Water rights for the mill have been obtained by the purchase of 20 share of
stock in the Left Hand Ditch Company, which entitles C.O.M. Inc. to a pro-
rata share of the water available from Left Hand Creek. Based upon the

vert the water associated with these shares from a point of diversion located
on the south bank of Left Hand Creek, on property which it bought for this
purpose. 'I$ese diversions were made at a maximum rate of 50 gallons per
minute during the irrigation season, which extends fim April 1 to October 31.
A continuous measuring device was installed at the point of diversion. Access
was granted to the Left Hand Ditch Company's representatives, and to the
State of Colorado a water officials, to enable them to monitor the amount of
water being diverted for milling operations.
From the point of diversion, the water ie pumped 3,900 feet up Akins Gulch in
a 1 inch diameter pipeline, that is situated on property purchased by C.O.M.
Inc. At a location 45 feet below County Road No. 52, the water line enters the
portal of the 'ilme mine's adit, which passes beneath the county road and ex-
tends 395 feet in a southeasterly direction. The'I'rme mine is connected with
the first level of the Wynona mine by way of a 50 foot deep winze. By con-
