Show MONTANA BINGHAM MINE HAS BIG TONNAGE f 1 Werner Wemer Lawson California i Expert Makes F Favorable a v able Report on Property Ii Developments to date have hav not begun to disclose the sizo size of oC the remarkable block Pf ore lying between en the No 7 and 10 raises from which tho the company Is now its Us milling ore according to A. A Werner Verner Lawson an eminent mining engineer engineer engineer en en- of California who has just completed completed com corn examination of oC the exhaustive an n Montana BIngham Con Consolidated Mining properties He has submitted his hs report to the board of oC directors of oC the company The report according to tho board Is highly favorable showing that the company has already vast tonnages ton ton- nages naJe's of oC copper ore blocked out In discussing tho the block of oC ore In the Fortuna lying between No 7 and ana No 10 raises from which the company Is 15 now mining a P. large portion of Its milling ore Mr Lawson says sars Existing development does not begin to disclose its limits but a portion of it has pointed out between chutes No 1 and No 10 as aa Quite fully developed This block Is feet Ceet In length and Is de developed de- de eloped by No 9 ral raIo e to a height of feet by No 2 raise t to a 3 height of over leo lcD feet and by other raises to a a. height of oC over sixty feet above the tunnel level Basing my estimate of the value alue of the theore theore theore ore ore in this block upon the tho average mill heads of ot all aU the tho ore broken in the dei development development de- de i and upon my own sampling j klch checks this very closely the avert aver fige minimum value alue of ot this ore is taken at ati i pr lier cent copper content j I THIRTY HIRTY FEET OF OREAs ORE e As exposed in the Mayflower r drift ore ranges from six to thirty five feet Un width it might be stated here that one crosscut has shown a width of oC et and In none of oC the crosscuts has ato foot wall yet been reached at right I Angles to the bedding In No 1 raise a ai i thickness of ot over twenty feet was broken In the new crosscuts opposite In No 13 la 3 raisa a thickness of oC over thirty feet Is exposed with ore in the foot Coot wall All AU f gf the slopes and md raises are driven on onre ore f-ore ore re with a thickness ranging from sIx sir to toI I ten feet and all have ore In Jn the foot toot wall walland and nd hanging wall In all the tile drifts drIfts' a j thickness of ot at least six sic feet Is exposed 1 WIth ore continuing on in the foot wallIn wall In addition to the tonnages of milling ore bre re as s Just outlined there occurs throughout through- through out ont the tha workings of oC the Fortuna mine on onI I nil all its levels and on all the veins occurring occur- occur f iring ring in It it an aggregate of very consid- consid erable tonnages of the heavy p I t ores to the railroad large tonnages ton- ton 1 nages of this material can be shipped and very fair profit netted from Crom it in view Fox I of the fact that the smelters are ex- ex f. f desirous of obtaining this ore and I the smelting charges on these ores with their high ore content Is practically nothing MILL WORKING WELLin WELL in In discussing the the- mill mm on the Fortuna eide Ide of the property Mr l Lawson says At tho the present time tima a concentrating t mill o of ton capacity is rapidly near- near i r i ing ig g completion For the past five weeks It has been in operation on a limited scale and teat treating ng fifty tons dally daily The result r of or this work has been very gratifying and I t 1 recoveries have been very W-o W t. A- A rough estimate made at this time I fit the mining and milling cost to be Approximately 3 per ton and on 2 per percent cent nt tore ore at the present price of ot copper P ct profit of oC at least 5 is realized on ton of ot ore treated The treatment costs will be very greatly reduced as soon c the is s running to capacity for It j I costs just as much now to operate the thel ji l 1 on a ton fifty-ton dally daily capacity as it I be on a ton capacity Also with C the further opening opening- up of ot the mine the ther r f costs will ill likewise be reduced j- j It It might be stated with relation to Mr t- t statement concerning the mill tl that the company expects to have the mill eted to a ton capacity by the I Math th of the coming month I |
