Show CALI FORNIAS MINERAL PRODUCT IS ESTIMATED AT the total value of Cali fornias mineral production for the year 1926 as shown in the estimates of lloyd L roo t state mineralogist was in the bureau of mines estimate prepared by J M hill and published by the review two weeks ago only gold silver copper lead and zinc were figured the fig figures ures given on those metals varied but little from tho those se contained in the state fists compilation but the latter goes much farther afield for his figures though he has only been able to report on the value of fifteen or sixteen mineral products of the states sixty five or more to obtain the totals he presents herewith the main items in the lloyd report without considering the output of gold silver copper lead and zinc embrace petrol petroleum eurn natural gas cement and gravel but let mr lloyd tell it petroleum is states chief mineral product the estimated total of is an increase of approximately over the 1925 production which in turn surpassed the previous record value of the year 1924 this increase is due mainly to petroleum and in part also to fo cement and other strut structural tural materials although there was a decrease of approximately barrels in the quantity of crude oil the total value is higher by around owing to an advance in in prices effective from march il 11 1925 and continuing throughout the yearn year approximately 85 per cent oi of the crude oil at present produced in california is above 20 baume some of it testing as high as 50 B while grade oil ranges down to 90 9 B current prices range from per barrel for 14 20 crude in the san joaquin valley field to for 43 crude in the athens rosecrans dominguez domingue group receipts of bullion at the mint and smelters shelters sm elters show a decrease in gold yield of about compared with 1925 the drop being chargeable to both lode mines and placers except dredges which mainwal maintal maintained ned practically their same level the drop in silver was wa s due to closing the california rand silver mine and to decreased copper ore shipments the lesser copper output was due to shasta county mainly but in part to plumas county there was a slight increase in leadore lead ore shipments and about 50 per cent increase in zinc the latter including shasta county and santa catalina island although quicksilver prices advanced materially teri ally during 1926 closing the year at 99 per flask there was a decrease in the quantity produced owing to closing down of the new almaden and cloverdale mines cement and gravel important features As building continued active throughout 1926 nearly all items of the structural group will show increased quan titles and total values especially cement crushed rock sand and gravel shipments decreased due partly to there I here and lower prices 1 maintenance of foreign importations were ere no notable changes reported in the general status of the miscellaneous industrial group nor among the salines the estimated quantities a and nd value for 1926 are a as I 1 follows J gold silver fine oz copper lb ib lead ib zinc lb ib quicksilver flasks flacks platinum fine oz i other metals including antimony iron manganese tungsten petroleum bbl abbl natural gas M cu ft cement bbl abbl crushed rock sand and gravel brick and hollow building tile file tons crude other structural materials including granite et al 1 miscellaneous industrial minerals salines including borates potash salt sait et al total value |
