Show GOLD SILVER COPPER LEAD AND ZINC MINED IN california SHOWS INCREASE tile the value of tile the gold silver copper lead and zinc produced in california in 1924 as estimated by J M hill of tile the geological survey amounted to an increase of over the value for 1923 tille the increase is due entirely to the much greater production of copper for the output of every other metal was less than in 1923 the gold produced in 1924 is estimated at ounces valued at as compared with ounces valued at in 1923 the production of gold by dredges apparently declined about 25 per cent as compared with 1923 when five more dredges were in operation than in 1924 other forms of placer mining were also les le s productive than usual because of the severe drought in 1024 I 1 the deep mines on the other hand increased their output of gold particularly the mines mines in in am amador d do rN nevada iada and sierra counties the silver produced in 1924 is estimated at fine ounces valued at compared with 3 5 ounces valued at in 1923 the de decrease would hai have C b been cen larger but for the great increase increase in the file mining of copper ore which yields also some silver for the output of silver ore at tile the california rand was restricted for a time and the lead mines which also produce silver were not nearly so active as in 1923 the copper mines of the state which were particularly active in 1924 produced pounds of copper valued at as compared with arounds pr valued at in 1923 the great increase was due largely to the Marn mammoth moth and calaveras talaveras Cala veras copper companies both of which were operated through the whole of 1924 after beginning production late in 1923 the walker mine increased its output considerably but the engels mine was working at a slightly b reduced rate during part of the year on account of development work copper was produced late in 1924 at the bully hill mines which were reopened by the california zinc company primarily as a source of zinc oxide the production of lead in 1924 is estimated at pounds valued at as compared with pounds valued at in 1923 all the lead mines which are in the southern part of the state were working on short power due to the severe drought the output of the tecopa tecola and darwin mines was much less than in 1923 and the slate range did not operate at all lut aut the estelle cerro gordo and santa rosa increased operations and a few smaller operators entered the field california again becal became lle a producer of zinc late in 1924 with the reopening of the bully hill mines at winthrop shasta county the mines were reopened in october and smelting smelling sm elting was begun in november the zinc is recovered as zinc oxide and leaded zinc oxide for use as pigments the zinc content of ore mined in 1924 is estimated at pounds valued at no zinc was produced in california in 1923 |
