mill with all the water necessary, which really makes the
pumping item of little expense when tho difficulty of secrr.
ing milling water in some parts of the desert eountrv ara
considered. The work which is being done in the meantime
is on the 300 and 400-foot levels; development work in mart
and IA part improving the physical conditions of the
working.
A body Of ore, which is more than 30 feet in thickness.
and fifteen feet of which gives ear assays of better than
$50 per ton, has been opened up by drifts and crosseu,s i,
the 200, 800 and 40Ofoot levels, this body of oe which hos
been proved up alone being sufficient to keep the mill rur.
ming for six months at a conservative estimate. On the
dump on which the rock from this ore shoot has been
dumped is enough ore to keep the mill running more than
three monthc more. This dump will give values, from gen,
eral grab samples of $50 Per ton, and paintings which
we made on top of the dump Wednesday, and after a series
of heavy rams, showed strong colors of free gold.
Formation Of the Maynower
| sampled the ore shoot freely in the various places
where it is exposed on the 800 level, and the samples almost
without exception showed free gold in abundance = some Of
them with little stringers and lunches of the yellow metal
were most ailuring. The ore is a breceiated, silicifed rhyo
lite, with %porphyry contacts, and the values occur in string
es of quartz, or highly altered and silicifed rhyolite, which
are shot through the rhyolite. In fact, the rhyolite is the

silicifcation.
At the 500foot level, where water has caused a tenn
porary suspension of operations, there seemed to be 70
change in the formation or in the values, and no trace Of
%su1phides, so to our mind the formation holds out much
promise of permanencv at great depth.
The new mill on the property is equipped with five
Hendy stamps; q 30ton cyanide watts, and an ama.gama-
ton plant with which to handle the product from the watts.
The stamps will crush to 30 or 40 mesh, the complete prod
net of the stamps going direct 10 the watts and thence
after potassium cyanide treatment, going through the zinc
boxes. Manager Arlington states that laboratory and re-
duct;on plant tests have shown a saving of over 30 per cent
in values by this process, as the ore is singularly free from
s~ulphides and hematitcs, and he figures that the mill will
make a saving in operation of about So per cent. He states
that the mill is but for the development of the property,
and that the present amount of ore in sight will keep the
plant running for nine months; keep two drills running on
ore extraction and three on development and prospecting
work in the meantime; and that when this has been done,
the company will be in shape to put in a large and COM
plete milling plant without going in debt. This without un.
covering another pound of ore.
From all appearances, the Mayaower is destined to be 4
big, paying mine.
Sunrise Pioneer
The Sunrise Pioneer Leasing company is preparing its
articles of Incorporation and has commenced operations on
a block of ground on the Sunrise No. 2 claim of the May
flower North Extension Mining company's estate. This
property sidelines Bimetallic claim No. 3, its endline being
800 feet from the ground of the Pioneer lease, and its
working shaft $50 feet east of the shaft of the Pioneer
Leasing company.
Work has been prosecuted on this property, which is ia
the westerly edge of the TOWNSHIP, for about two weeks,
and its double compartment working shaft is now down As
feet. The shaft has been cutting through a sedimentary
conglomerate, which carries small values leached from the
mineral veins in the hill above, and solid formation has now
been reached. This is a silieifed rhyolite breccia, soft as
yet, and stained by oxidization of its contained iron hema-
FL. .bo.foto broxvn aolar The rock is becoming
harder and lighter in color, and is of the nature which
ebaracterizes the ore holding and forming stratum of the
district, generally speaking. There is a big qnartzIte dyke
cutting the hill Just above the working shaft, and when
depth is reached, prosecuting will be commenced to reach
the contact zone of the quartzite and rhyolite rocks
Arrangements are being made to secure sufficient funds
to inssall power hoist and needed mine equipment, and to
continue sinking and development to sufficient depth to
penetrate the ore bodies which are believed to lie under
meath this ground, and ascertain their extent and values.
J. r. Bryan, under whose management the Pioneer lease
developcd into a bonanza, is at the head of the company AMI
experimenting its mining operations.
The Town Still Growing
As the last of this article is written, Friday morning,
the sound of the saw and the hammer is heard from an
sides. and gangs of men and teams are still busily engages
ia oradino streets and foundations for future buildings,
Building operations are as extensive as ever, although now
devoted in the main to the building of substantial frame
and corrugated iron structures. This is slower work, anu
does not make for the mushroom, over-night-lIke growth
caused bv stretching of tents and tent houses. One of the
. structures at least, will be built of rough stone, being
the remains of the giant quartgite bouiders which nave pesh
blasted to fragments in the grading operations. Two big
frame hotels will soon be under course of construction, and
there are half a dozen or more good sized frame store and
Office buildings in course of erection.
The town itself does not seem so lively by day as a
week 400. The leasers are scattered through the hills, and
significant of the turn from TOWNSHIP to mining activity was
the organization of a branch of the Miners Union Ihnrs-
dav night. The weather, too, is fine as could be desired
and does not force the prospeeiors and miners to hang
about the town.
