MARCH OUTPUT OF REFINED
LEAD HIGHEST IN TWO YEARS
pRODUCTION of refined lead in the
United States during March was the
highest since April, 1942, according to
the American Bureau of Metal Statistics.
Total refined production went up to 65,-
324 tons, of which 47,294 tons were from
domestic ores and 8,030 tons were from
secondary and foreign material. This
brought the total for the first quarter of
this year to 153,394 tons, as compared
with 137,250 tons in the corresponding
quarter of 1943.
Shipments of domestic refined lead in
March were 55,449 net tons as against
61,367 net tons during the preceding
month. The March figure' represented a
new high for the current year as well as
the highest shipment total since August
1942. These figures do not include foreign
lead which is shipped monthly out of stocks
owned by Metals Reserve Company.
Total shipments of domestic refined
lead for the first three months of 1944
amounted to 152,074 net tons as compared
with 137,071 tons for the first quarter of
1943. Increased shipments to cable manufacturers
and battery manufacturers were
largely responsible for the advance.
At the close of March, refined stock
of lead in the hands of producers totaled
34,379 tons, a slight decline of 139 tons
from the February figure. This does not
include the huge stockpile of foreign refined
lead currently held by Metals Reserve
Company.

HYDRAULIC MINERS DISCUSS
CALIFORNIA DAM PROJECT
ROBERT C. HUNTER, district engineer
of the U. S. Engineers and secretary
of the California Debris Commission, discussed
the proposed federal darn project
at Bidwell Bar, California, at a joint meeting
of the California Hydraulic Mining
Association and the Oroville Chamber of
Commerce, held last month at Oroville,
California.
The proposed dam, Hunter estimated,
would cost about $43,875,000 and would
store 1,200,000 acre feet of water. The
new structure would be erected on the
Middle Fork of the Feather River, about
eight miles above Oroville, and would
drain an area of 1,338 square miles. The
reservoir plans call for concrete gravity
or arch type construction, and the dam
would be 696 feet high, with a normal
pool area of 5,900 acres.
Warren T. Hannum, newly elected director
of natural resources in California,
also addressed the meeting. He stated
that, if the four debris dams authorized
under the Englebright Bill are completed
and successful, there should be no· reason
why Congress should not authorize expenditures
for dams in other districts
where hydraulic mining can be conducted.
He said that the water could be used for
multiple purposes, including storage and
hydraulic mining.
George W. Hallock, Alleghany, California,
is president of the California
Hydraulic Mining Association.
DAM PROJECT FOR MEXICAN
MERCURY AREA IS APPROVED
RESIDENT A VILO CAMACHO re­
P cently approved a project for the construction
of a dam at Mitzuco, Guerrero,
Mexico, and work will be started immediately.
The cost is estimated at 1,000,000
pesos, and when completed the new dam
will supply water for 10,000 hectares. The
construction work will be pushed as rapidly
as possible, it is reported, because
operations of mercury mines in the district
have been suspended as a result of
the insufficient water supply.
