Los Angeles herald., 1905-11-06

company has issued it's annual report
showing that $9,472,015 was the gross
value of copped produced. The opening
expenses were $6,666, ,62S, leaving a net
profit of $2,S05,3 3S7. The construction
account absorbed $S32,000. leaving a
balance of $1,974,3S7, of which $1,900,S00
was paid out in dividends and $73,3S7
carried to the surplus account. A total
of 62.S3S,S S12 pounds of copper were pro.
duced at a cost of 1916 cents per pound.
Adding construction, the copper cost
was 11.9 cents and the price averaged
14A cents.
| In Montana the output of copper for
the first nine months of this year would
Indicate a yield for the year of 335,0OO,-
900 pounds, against 267, ,500,00 in 1904,
an increase of no less than 25 per cent.
Much of this large increase is due to
the North Butte, which has thus far
in 1905 produced 13,743,750 pounds of
copper, against a nominal output a
year ago. The noteworthy feature of
the Montana figures is the drop in the
production of the Amalgamated proper
ties, which show for September the
smallest months total of the year-an
amount which is over 100000 pounds
less than in January last.
San Diego Company
The San Diego Mining and Develop
ment company has been organized for
the purpose of acquiring lands, mining
claims, etc. particularly in the repub-
lie of Mexico to build ore smelters
and conduct other business necessary
to mining The directors are George
p Bauerline, William II. Wright, ]. G.
Mcknight, A. ]. Bradley, E. T. Huff
and j. II. Richey, all of San Diego.
The capital stock is $500 in shares of
81 each, of which $500 has been sub
scribed, each of the following taking
forty-one shares: George p. Bauer

Concerning Deep Mines
Payable ore is still found in the
deepest gold mines of the world-those
of Colorado, California and Victoria,
Australia, says the Mining and Scien-
tiic Press. The latter are down 1000
feet, with pay ore still in sight The
deepest California mine is down about
2S00 feet. with good ore in the lowest
level. Some Colorado shafts have PEN
etrated below the 1000 level, and the
mines Still are prosperous. At what
level may we expect them to become
barren? Deep mines may become un-
profitable because of increased ex-
pense, while the value of the ore re-
mains the same as above. On the
Rand, in the TransVaal, for instance,
the collaborating blanket continues to
produce nearly the same average val
ues as above, while the expense of
mining increases as the levels are car
ried to deeper and still deeper levels,
this being due entirely to economic
and not geological conditions.
A careful review of all that is known
of the genesis of ore deposits, and par
ticularly of secondary enrichment
leads to the inevitable conclusion that
there still remains much to learn about
both original and secondary ore de-
posits. At one time secondary enrich
ment was not recognized as an Inn
portant factor In mining. but a study
of the remarkable phenomena of the
ore deposits of Butte. Mont, forced
the conclusion upon the observing en-
gineers that the rich ore bodies OF some
OF the great mines OF the district were
due wholly to secondary enrichment
No one now doubts that the phe-
nomenally rich ore OF Fryer Hill, at
LeadVille, Colo, Treasure Hill White
Pine, a score of places in Arizona and
Nevada and elsewhere, were due TO
similar causes. The gold mines of
California owe their surface richness
10 the same cause. The notably rich
deposits at Goldheld. New. must be
ascribed to this secondary enrichment,
as must almost every other occur
