 Concerning the development of the | ere deposits of the Bradshaw Mountain Copper Mining & Smelling Co. near the Bradshaw Mountain railroad and the methods of ore handling employed, the Prescott Journal Miner says:
 One of the things done by G. W. Middleton, the manager, was to drive a big cross cut tunnel into the side Of the mountain to cut the ledge at a depth of about 1900 feet from the apex of the mountain. This tunnel is wide enough for e double track mining raii- road and its length Is about 1100 feet.
 At a distance of HOO feet in a drift was run and an ore body encountered. into which they have already run q distance of sixty feet while it is known to be sixty feet wide at this point with out having encountered one Of the walls.
 Five hundred feet above this or abo1t 800 feet lower than the apex of the mountain, ore was struck some time ago iI tunnel. A winZe 200 feet deep was sunk in this ore body and then a cross cut was run at this point d distance of fifty-siX feet, showing the ore body at that place to be of that width
 This upper tunnel is known as the Copper Link tunnel to distinguish it from the big tunnel which is known as the Hot Number tunnel being rn a claim of that name. This tunnel, while run parallel with the ledge, was run for some distance on barren rock. In a cross cut run from it a body of ore was encountered which apparently
 demonstrated the great magnitude of
 the mine but nothing was said about it, MT. Middleton preferring to prove the extent of the ore body before mak- ing any rash announcements. Work was pushed in the development of this
 ore body until at the present time they
 have drifted on it for sixty feet and
 have extended the cross cut for nearly
 sixty feet without finding the wall of the vein.
 This immense ore body is directly over the one in the Hot Number tun-
 mel and the ore in the 2O0-foot winze
 sunk from the Copper Link tunnel. In
 tunnnel still nearer the surface the same ore body has also been encount- cred, the character of the ore being diff 1 ferent and the extent of the ore body | not having been yet determined. The width of this ore body has been prac- | Jically determined by the various cross
 cuts to be at least sixty feet while the | face of the drifts in both the Copper Link and Hot Number tunnels are still i in it so that the length of the ore body has not yet been determined. The depth of it cannot be approximated be- | yOnd the 1860 foot level from the sur | face where it has been opened up in the Hot Number tunnel.
 This ore body, however, at it's pres ent known size together with others which have been opened up in the property, is sufficient to class it among | the big mines of the territory and it | carries good values in both copper and | gold with a percentage of silver.
 On the surface over this ore body are immense croppings from which the
 ore has been leached leaving only the barren rocks sticking up, but sticking ! there as evidence of once having been
 a part of this ore body. Just across
 the gulch from the Copper Link claim
 on what is known as Mckinley noun | tain. and on a claim of the same name, | rocks of this same character outCrop | to even a larger extent and more prom | inently and by a logical process of req sOning. it is believed these outcrOp- | pings are where the largest and rich
 est ore bodies may be expected.
 Remarkably good progress has been | made in the development of the prop e-ty and the output of the mine is
 only limited by the capacity of the
 shelter in it's treatments. the, ship
 ments being from three to four car | loads per day and all being secured | from development work.
 | The aerial tramway constructed for
 carrying the ore from the mine to the
 railroad is a marvellous piece of ma | chinery and from the time it was first | started up to the present has not given | the least trouble. Buckets with ca
 pacity of about 1,200 pounds each of ore
 are strung on a stationary cable by
 means of pulleys and then by means
 of a clamp each bucket is fastened to
 a. smaller moving cable, and in these | transported between the mine and
 railroad a distance of 40OO feet. The
 cables are supported on immense wood
 en derrick shaped towers erected at | short distances apart, and with only | a moderate rate of speed sixty tons of
 ore per hour can be carried. The
 tramway is run solely by gravity, the
