MINING INTELLIGENCE.
A visit to n Couple OF Prominent
Mines.

Yesterday we set out at an early hour to
visit the mines on Prospect Mountain.
Several unfortunate detentions belated us
80 much that We could only crafty our
selves by visiting two OF the mines; We,
however, promise ourselves mother trip in
a few days, and hope to see and learn more
Of the great mineral belt Of this district.
AT THE HAMBURG NINE.
Upon walking into the hosting works of
this mine, we were met by Mr.. Powell. the
Superintendent; Mr.. Read, the Surveyor,
and Mr.. Kermeen, the Manager. We were
very kindly invited to join the party. who
were going below, as Mr.. Read had come
up to the mine for the purpose Of making
surveys for connecting a drift on the 600
foot level with one on the 450-foot level.
Here we may say that the first time we had
an opportunity of witnessing one o those
feats performed by mining engineers.
when they find it necessary to make a leap
through space. Mr.. Reads performance
was most creditable and successful; he
made the journey by clinging to q rope,
and was lowered down 40 feet into a wiuze.
Messrs. Powell and Read soon after left for
Eureka. and Mr.. Kermeen very kindly
conducted US through the mine. We were
particularly struck with the manner in
which the mining here is conducted. The
work is being done with a view to thor.
oughly open up the ore bodies ut the least
expense. Fortunately for the owners Of
this property, the territory in which they
are mining IL very easily worked, aud re-

found in a limestone formation. which lies
between a blue shale on the south, aud
quartzose on the north. The ore body,
which is very distinctly traced, runs north
and south. and pitching northe asst. The
shaft is down 600 feet, having been sunk
in the shale, which constitutes the hanging
wall. The limestone, or ore-bearing rock.
is $40 feet wide at the 400-foot level. From
the 250-foot level we went through the
slopes above, aid then proceeded down
through Slopes to the 400-foot level. We
were much pleased with the show Of ore in
this mine, and the manner in which it Is
being worked out. There are 80 men en-
ployed here, and an average of 40 tons Of
ore are shipped daily to the Atlas furnace.
The hosting works are in admirable con-
dition, spacious and well arranged, and the
machinery works like a charm. At the
CONNOLLY NINE
We found Mr.. Thomas Robinson. who
lost no time in taking MS back $50 feet
under the mountain, through q drift, to
the ~engine-room. The location OF the ma
chincry is LAG feet below tho surface, and
this, as a point Of economy in fuel alone,
must be very considerable. The machinery
was in first-rate order, and did its work to
perfection. This mine is being worked by
means OF an incline, at an argyle Of 81
degrees. We were lowered to the 2i6-foot
level, and landing there, procsedcd back
l04 feet to the ore-bearing formation,

lying between q gray lime and quartzose
matter. the lime constituting the foot wall,
and the quartzosc rock, the hanging wall.
There is y very large body of low grade ore
averaging 20 feet in width, and extending
back ON either side Of this drift for 200
feet. This ore will average S25 per ton.
and as the Connolly ores arc SO admirably
adapted for using as a iux for the basic
ores found in this camp. in such large
amounts, the time must not he very FAR
distant when this body will BE- mined at 4
profit. A VINO from this level, pitching
at an angle Of AZ degrees, has been sunk 90
feet. and is now piercing a body Of high
grade ore, which promises to develop into
something handsome; this Wine is to con-
meet the 2iG-foot and the 31G-foot levels.
On the 3lG-foot level the drift is in 146
feet; this is being extended, and it is cal
culated that il will pierce the ore body at
about ITS feet from the main incline.
