Year: 1875

indubitably deserves, a very complete deyelop-
ment. The frequent show of ore that leads the
miner onward seems never wanting here if the
rule have endeavored to explain is adhered to.
and th remembrance of what the place yielded


in it's upper levels should be sufficient stimulous
to foster continued exploration. The other
mines of the company consist of the Iceberg


Jefferson, East Idaho and small portion of the
Colfax. There is nothing being done either with
or without them, excepting from the first
named ; and believing that all the effort the
company is capable of making should be spent
in endeavoring co learn what the hill con-
tains in depth, recommend their being left to
abide time when more is known about the
ground Tunnel below Treasure Hill This
emanaied from Capt. Drake, and was writ
ten about in his report of list of February 1875


1t is d bold scheme, which, if fortunate in find
ing ore as it cuts throughthe ledges at the depth
it would penetrate the mountain, would materi-
ally change the feature of the company's pros
poets by wlplng away many causes of expense
that now bear heavily upon the work, and by
giving assurance of comparative perpetuity to
the company's existence. There are two direc-
tiOns that can be chosen for getting into the
mountain at a level of 800 feet below the ex-
treme highest point of Treasure Hill known as
Treasure Peak. For elucidation of the subject


l beg to ask you to inspect Typographical map
of Treasure Hill. drawn and published by
Messrs. Hall and Dickins, in 1869, engraved by
Linton, of Philadelphia, copy of which is said
to be in London. 1t is perfect survey as
could be made by the Ordnance Department of
England and gives the exact levels at every
twenty feet OF ground below the summit alluded
to, to the distance of from three to five miles
radius. One entrance that might be selected for
the tunnel will be found on the east side, about
half an inch west of the line which marks
Browns survey; from that pc mt straight line
measures $500 feet to spot vertically below the
various chambers of the North Aurora allowing
for a continued dip of As deg. the north and
south wall should be intersected by such tun-
mel after it had been driven 2 534 feet An avail
able entrance for the other tunnel is in the linn
its OF piece of land marked out on the same
map to the south southwest OF Treasure Peak


and called 'Thomas's Survey Near the south
east corner of that survey is the number 098
and that is on the 1,500-feet level line. From
that point to another east of Eberhardt (which
should be passed on the east side, SO that the
tunnel might run under the Aurora properties)


is 5000 feet, and this reduced to catch uniform


dip of IS deg. from surface gives about 4500
feet for the point of intersection. But as the
tunnel should not be designed to reach the Eb-
erhardt only, the deduction for the dip does not
enter into the calculation. nor in fact, need such
deduction be allowed element of the other.


Both tunnels, if successful, would have to be
driven to at least their extreme vertical dis
tances, which may be fairly laid down at 1000
feet if the first, the Applegarth canyon one is
taken; and $500 feet if the choice falls on pen
etrating the hill from the south, from a
canyon called the d" Mahogany" and it is driven
past the Eberhardt wall under the Aurora mines


endorse Capt. brakes original estimate that 81


per Hneal foot is none too mnch for either job if
it be carried through; shorter distance might


proportionate less. The object to be gained by
tunneling is to give the mountain mines more
determinate trial in the briefest manner and


looking at the very vast Importance of carrying
out something of the kind think the field you
are laboring deserves such exploration. The
company has in its mines two guide stones,
which so far as they have been kept to yet, have
proved unerring and l frankly say that | be-
lieve the time is rapidly approaching when it
will be the duty of those entrusted with its in
terests to call for decision from the share
holders on the respective merits of those two
counsellors, or as l believe them, g Guardians


the north and south, or the east and west walls.
Such an undertaking in the present condition of


matters may appear chemerical to many. but it
will not be so, l confidently hope, for long, for
on the very earliest discovery Of an important
body of ore in the deep workings of the North
Aurora or the Eberhardt, the matter should in
my opinion, be pressed Oh the consideration
OF all concerned for sanction and support. 1t is
now necessary to revert to the Eberhardt, which
have hitherto only described. A small trial of
about weeks duration was consented to by
Capt. Drake since have been upon the ground,
and the existence of north and south wall
shown by it, but whether continuation of the
wall with the same bearings in the North Aurora
cannot yet be decided. This trial was on the
lowest 1921 fathom) level, and the north and
south wall there gets lost before it arrives at the
east and west. Now, it is important to learn
which Of these walls is master of the position
lower down, and / hope that the sinking of the
winze (which have noted as having been aban-
doned at fathoms), until it comes into contact
with the north and south wall lower down, is
not work you will object to, although now to
be undertaken without permission. 1t has 80
feet to 60 before it can reach that destination,
so that | shall be in all PROBABILITY in England,
and able to discuss what further think neces-
sary to complete the dead work of the trial.
which is the following of the wall north until it
is either lost (as it was above, intersects the
east and west. In the possibility OF full con-
sideration Of the tunnel question: it is essential
that the Eberhardt should be more on an equal
ity with its sister mine the North Aurora, by ex-
plorations in depth, for there are many reasons
tcaeteris parbus in the mining prospects) why the
Eberhardt tunnel should be selected Its mouth
would have a greater proximity to your mill


"A, 500 feet), towards which the tunnel debris
could be used to grade double line automatic
tramway; /; and what is more to the purpose, it
would first intersect the unworked patent have
already alluded to when speaking of your own
stray mines. finish this subject by venturing
to hope that the Eberhardt and Aurora might not
go altogether single-handed to the work. You
have neighbor as much concerned in the pros
perity of such an enterprise as yourselves, and
there is no way equal to it in mining prospects,
in which any means they may have at disposal
could be diverted. The mill The completion
OF tnat construction at the cost which IS
charged against it in the balance sheet re-
bounds to the ingenuity and care of your Super
tendent. 1t works smoothly and with precis-
ion, but If in the future it should happen that it
required more stoppages than are customary,


trust it will be borne in mind that it's machn-
cry is Phoenix from the fire, which inflicted on


the company, imagine, much greater loss
than the insurance company allowed for. From
what understand was the deplorable condition


OF the engines when rescued, it is surprising to


me that the one in use could have been restored


as it is, in machine shop of such limited ca
paclty as exists at Eberhardt. 1t requires study
to become an fat with mill work and prevent
waste. Its power of thirty stamps is for the
present quite sufficient for the places purpose
Inc water This subject brings up the White
Fine Water Works, the acquisition of which
consider from the knowledge I have gained of


the LOCALITY might have been avoided, even with


the prospect which the company had then before
IL, OF working continuously sixty stamp mill.


The weight OF bad bargain is now felt heavily
IN the general costs, and perceive no method


OF betterlng the position. Greater economy
cannot be practiced unless at the risk of damag-
ing the plant, which is intrinsically worth more,
in these parts, than the company gave for it. If
the day again arrives that population and wealth


will be attracted back to the many town sites
around and upon 6 Treasure HILL" the posses
sion OF these works may become lucrative bust
ness; and as it appears to me that such well
come advent is by no means beyond the posi-
bilities of year or two, I recommend the prac-
tice which | notice has never yet been relin-
quished, of still securing natural springs, and
water locations in the vicinity of your works.
