Bisbee daily review., 1911-07-23

What appears to be a big deposit of to per cent concentrating ore is being opened up. and the remarkable thing about it is that 1 it looks like granite-porphyry
 sulphids Ore.
 All of the development work done on the 10th level has been in sul- | rhide ores. The central ore shoot | makes somewhat disappointing 1 showing On the bottom level as it did also on some of those above; but both Of the others. east and 1 west. are opening up splendidly.
 The belief held by some that as the old Dominion has six furnaces and is operating only two Of them, it is in a position to increase its production to three times it's pres ent volume is in error Several years ago when the company was ! buying large amounts of sulphide and iron ores for flux the furnace capacity of the shelter was in creased far beyond the capacity ot its own mines.
 The shelter is twice as big as the old Dominion will need for many years: but as the development of this district goes on it may eventually be used profitably for custom work T. is one of the best plants in the country.
 The reason Old Dominion did not remodel its plant and arrange to smelt the Miami concentrates vas lack of sulphur. It seems that l these concentrates do not carry quite enough sulphur to matte them. | Within a year or two Old Dominion may be in a position 10 handle concentrates from the Miami dis trict profitably, however.
 What old Dominion is beginning to feel the need of now is more concentrating capacity. Its mill was built 10 handle 500 tons daily. but it's capacity seems to be nearer 500 tons. Plans for an addition to the concenuator are now being worked out by a concentration spe ciaiist.
 For perhaps the first time in its career the Old Dominion has Q three years supply Of ore blocked out in advance. at the present rate of production. Beyond this the future of the property depends upon deveI Opments at greater depth. The worl,
 of sinking the shaft will be re
 sumed very soon.
 Prospects Now Fine.
 There never was a time in Old
 Dominion's past history when its prospects. the condition of its property and is cost were as sat | isiactory as they are now. More 2 copper could be produced; but ar increase or a decrease in its out
 put would raise the cost per pound [, The management expects to produce
 25.000 pounds of copper at @ cOs' , Of slightly less than nine cents . I, pound this year, from old Domin ion and United Globe ores. On . . 15-cent metal market this would giy, r the company net earnings Of S : f share annually for it's stock. I
 should earn nearly S a share thi! q year.
 9 Incidentally it may be mentioned {, that Old Dominion is now buyinl l, only about GO tons Of sulphide ore I daily. These come from tho Coppe '. Queen. It is selling almost enousl |. water to the Miami for concentra = ton purposes to pay its pumpini . expenses, and it may sell nor
 Of it's water soon. About 5000. co
 gallons is being pumped daily. ol Old Dominion has increased it !. land holdings. on the west side O = Final creek. very considerably. It V westmost workings are still 2O . feet east of the creek. There is !. very good prospect that the yer :, rich ores in the west end of tn
 mine will be found to extend ia !, beyond the creek. under the be .r of congiomerate that has preyente ~ surface exploration there.
 High Graded in Past. For the benefit of those who ar V not familiar with Old Dominion -+ history it may be mentioned tha 'j from the beginning of operation
 it has been one of the richest cOI '. per mines in the world. In eaTi .I days when it was controlled D ,l Baltimore interests, it was "higl 5 graded and it's small smelter Ol
 erated continuously on 9 per cen a ores. As recently as 12 or !, years ago the ores smelted average ' 16 per cent. There are very fe1 '5 if any other big ~producers9 treatin e both concentrating and .smeltin ;g ores at present whose average .e ever 100 pounds of copper to th
 ton.
 Old Dominion could recover 20 and perhaps 300 pounds Of coppe a to the ton Of ore now if the maI
 aeement chose tO leave ati T5e lO' !, grade ores in the mine: but il
 stead of this it is mining and trea IT ing everything that contains 9 pc
 cent and some ore that runs as lo' .. as 2 per cent copper Every to 7. of the slag made in the old days ( = 'high-grading" has been resmeltei '5 Now that the sulphide zone ha
 been reached an increasing peroen
 age Of its ores will be concenTate' | The result will be a much highe | grade smelter charge, reduce i amount Of fuxes and a lower col
 per cost I believe old Dominion
 entering upon a career of gre' | prosperity and that within a fe years 1t vii be paying big di l idends.
