 Copper Co.'S Property BIGGEST MINE IN ARIZONA
At Least the Owners Be lieve it Bids Fair to Be come So. Assays Show 20 Per Cent Copper and 4 1-2 Per Cent Cobalt.

The discovery of cobalt in the Sad- dleback mining district west of Phoe- nix, has put the owners of the Palo Verde Copper company in the best frame of mind it Is possible to con ceive. Convinced before that they had a very valuable copper property. the adding of s1SO per ton tO the values of what appears to be an enormuOs deposit of ore, makes them think they now have the biggest mine in Arizona, in its development possibilities.
 The above information s disclosed by T. Baycroft. the superintendent. who has just received advices from c IF Rowland, the manager, with a re- port of assays made on 800 pounds of ore sent him by Mir. Baycroft to the latter's home in CuyahOga Falls, Ohio. The samples were sent in fifty pound lots and the assay of one shows 2062 per cent copper values and 4i2 per cent cobalt or ninety pounds tO the ton. As the cobalt is worth g. per pound iJ makes the ore return $lS0 per ton in the mineral. while the cop per values alone are sufficient tO sat iSfy the average mining man. Indeed much of the copper of the day is pro Iuced from ore that only carries half that value
 Another Of the samples was of oxide land carbonate rock. which gave an assay return of S1a per cent sulphur and II per cent iron, both valuable fluxes and the first time they have been found together on the property. Mir Rowland writes that a plant can be erected for approximately $150,00D sO that with the alluring prospects the company now has an estimate of the value of the property can hardly be made. He rather intimated in his letter that he had had a pressing fear that somebody might come along and buy it for a copper mine at an under valuation, but now with the cobalt discovery there will be nothing doius fin the selling line until after the owners have more thoroughly deter mined what they have on hand.
 The property has already been pret- tv we'll prospected for copper, and a description of the development work accomplished was published a few weeks ago in The Republican. Mir. BaycrOft says the deepest shaft is 120 feet and there is another 1i2 feet with Ia tunnel in about 13O feet. There are also two shafts of 50 and 40 feet respectively and numerous test pits land cuts. The ore body he says is between 600 and 700 feet wide and is known tO be about 21OO feet long He had always regarded it as a big low grade deposit but with a showing of % per cent copper and $1S0 in cobalt he is inclined to think his former es- inmates were ridiculOusly conservative.
 The samples sent for assay were taken as fairly as they could be. says Mir. Baycroft. who has no desire tO deceive himself concerning values One fifty pound sample was taken at ran dem from the best dumps and another was taken from what was regarded as second grade ore Another was from the pulled ore and another was taken from a shaft just as it came out of the ground without any sorting.
 The property Is located in the Sad dlerOck mountains range lying be- tween the White Tanks and Eagle Tails. both we'll known sections In the region crossed by the boundary line between Maricopa and Yuma counties.
