What Is Good Ore?


 a mining company in which the fol- lowing statement is made:
 "At an early date it is expected that the mill of the company will begin treating 200 tons daily of ore averag- ing probably 1OOs per ton, which would give gross production of 2O,- OOOS per day, and, on the completion of larger mill of 800 tons daily ca pacity, the lower grades, expected to average sos per ton, will be handled. ["
 Such stuff as this makes the conserv- ative mining man smile. The public's suspicious should be aroused every time such statements are presented to it. Few precious metal mines that the world has known have, for any great length of time, produced ore of such grade.
 The greatest producer of high grade gold ore in the world to-day is the Goldfeld Consolidated. The average value of it's ore milled to date has been around 30S per ton. True, the Hayes Monnette lease produced for about eight months ore averaging over 7OS per ton, but this was for eight months only, and the mine was meantime be- ing gutted of its best ore.
 The average value of the ore pro- duced at Tonopah is about 24s per ton. I icidentally the Tonopah Mining Go. is the greatest producer of silver-gold ores in the West, and one of the great est of dividend payers.
 The Camp Bird average seldow got above 3OS.
 The ores of the great Fl Orc mine, which pays over 10000 OS in net pro- fits yearly, average about SS.
 Homestake ores average about 3.50S per ton, and Alaska Treadwell about 2.30S, and are profitable because min ed and treated on a very large scale.
 The greatest mining companies in the Transvaal are Grown Mines, East Rlnd, Proprietary, Geldenhuis Deep, Robinson and Robinson Deep. In Grown mines the average yield from the ore mined and milled was last year a little above 6S per ton, in East Rand Props 6s, in Geldenhuis Deep about 5s, in Robinson about 1O.5OS and in Robin son Deep about 5S, yet Grown mines earns about 800, ,O0OS per month, East Rand Props over 5OO,OOOS, Geldenhuis Deep lOO.OOOS, Robinson 5,OOOS, and Robinson Deep nearly I5O,OOOS, On 6S are the two great mining companies of the Rand are earning substantially as much as Goldfield Consolidated is on its 30S ore. Grown Mines, however, mills about six times as much ore as Goldfeld Cons. and East Rand Props. about eight times as much. Some of it is hoisted from depth of 4,5OO feet.
 All of which goes to prove that the great mines of the world-the lasting mines-are those which have big bodies of low or medium grade ores. Given favorable conditions for opera tion-good water, plenty of cheap fuel or power, good labor, wide veins with sound walls, and no boUhersome metal lurgical problems-and the profit to be made out of los gold ore will surprise one.
 When mine promoter talks about mountains of sos or 1OOS ore," shun him as you would snake. The great mines are the milling mines whose ores run from 6S to l5S per ton.
 Mines like those of Cobalt, which produce yearly few hundred tons of picture ore worth from 500S to 5,OOOS per ton, are in class apart, and can not be compared with the long-lived, big-vein mines. Mines like Alaska Treadwell and Homestake, which mine and treat an enormous tonnage of very low grade rock, are also sui generis. There are only a few such mines in the world. It takes large sums to develop and equip them and it takes a well-oiled and well-organized machine to make them pay.-New York Mining Age.
