FACTS ON THE WORLDS GREATEST
 GOLD MINES.
How Much They Produce and What it Costs to get the Wealth Being
 WruHS from !cW Grade Ores

consider two important factors, to wit: the present net yield of the mine and it's assured future output.
 The nest productive gold mine in solIdated. at Gold6eld, Nevada, from which the enormous amount of $6,- 296. 476 in gold was extracted.
 The most profitable mine in the world in 1907 was the Robinson mine, near Johannesburg. Transvaal, South Africa, the net earnings being estima- ted at $4. 3OO,OoO.
 | South Africa whose largest mines are in the vicinity of Johannesburg now produces about 30 per cent of the | gold of the world. The South Afri- can mines are conducted strictly along commercial lines and their success is a brilliant tribute to their efficient man | agement.
 The average yield per ton of ore of the larger mines in the vicinity of Jo- hannesburg during 1907 was $8 and the average profits slightly over $3.
 Duripg the year of 1906 the net profits of the Is largest mines in the Transvaal were over $21, 100000, the exact figures are not available.
 The most profitable as we'll as the most productive mine in 1906 was the Esparanza Cat Fl Ora, Mexico). the pro duction of this mine during that year was $7.7Os. sS3 and the profit $4. .664,- 279. The average yield of a ton of ore was S33 "A ard the profit $20 33.
 The Alaska -Treadwell situated on small island a few miles from the mainland of Alaska is one of the most note worthy mines of the world. It las paid in dividends $9, 285 900 on capi talization of $5.OOO,OOO It's produc- 511, ,671. Of all the large mines of the world the Alaska Treadwell stands pre- eminent in that it has been suc- cessful in treating ore of the lowest grade and at the same. time paying large yearly dividends to it's stockhold- CTS. The average yield of a tor of ore at thu Alaska ka-Treadwell is S2 l5, the cost of extraction is $1 34 and the profit is eighty one cents per ton.
 The Homstake mine at Leads South DAkota, is another monumental illus tration of what gold mining along con- servative and commercial lines can ac- compish. To date it has paid in divi- dends disbursed at regular periods, $16,735 $50. This has been done not withstanding it is a very low grade mine. $3 83 is the average yield of a ton of ore and the profit is niuty- seven cents per ton. Much of the ore is ex- tracted from a depth of 600 feet. At the present time the output of the Homestake is S5O0,OOO Der month, of which S2OO,OOO,is net profit.
 The Homesteks operates a greater number of sta mps than any other mine in the world. Oue thousand stamps are laundering away day and night in it's mills crushing the ore. The Alas ka- -Treadwell is equipped with 540 stamps. The Robinson has 300 stamps When the new Eill of the GoldGeld Consolidated is completed 1t will have 12O stamps in operation.
 The Homestake and the Alaska Treadwell are illustrations of the fact that the gold mine that carries high grade ore does not necessarily yield the greatest dividends to the stock holders, in fact in this age, where min ing has been conducted on the same principles as other large commercial enterprises, the low grade mine yields in the end more dividends, than the high grade mine.
 In almost all big low grade mines enormous quantities of ore is blocked out long before 1t is crushed, and the management of the mIne knows in ad- vance that it has ore enough to kee ? bis stamp mill in operation for years to come.
