IRRITABLE BASIN
 OF COPPER.
Copper Basin Gives Fair Prom ise of Demonstrating That It Richly Deserves the Name Heretofore Given to It.
The Solution of 8 Mineral Problem Ap- psrentIy Found, the Key to It Being in Mammoth uIphide Dyke, Rich in Gold and Copper.

Copper Basin has for years been { puzzle to mining men. Every ont who has visited that section, and who has made a study of it has come away impressed with the fact that a big mine would some day be discov. cred there. The basin proper, or the lowest part of the immense area of country surrounded by high noun tains is stained with copper, while de- posits of conglomerate rich in copper have also been found and worked.
 Several years ago the Commercial Mining Co. spent probably a quarter of a million dollars in developing some of these deposits and in building an immense smelling plant, which was afterwards burned down, when they abandoned the field. They en- countered rich ore or deposits of rich copper bearing rocks, but experienced difficulty in treatment which partial ly influenced them in not resuming operations after the fire. The ore taken out by them was found lying in sort of blanket form and not in well defined lodges, and all indica- tions are that it was the result of a flow from some other point rather than the formation of ledge matter in place. The puzzle to mining men has been to learn where this flow of copper which so thoroughly impreg- mated the conglomerate came from. The only reasonable answer to the problem was that an immense dyke pr ledge must exist somewhere in the vicinity from which it came.
 After several weeks of the most systematic prospecting of the noun tain sides and gulches, higher up in the basin, by W. W. Munds, Thomas w. Kyle and Geo. A. Beach, they dis covered what they consider the solu- ton of the problem, in an immense sulphide dyke, running in northerly and southerly direction. This dyke varies in width from 100 to 300 feet. One wall is granite and the other DOT phyry and the capping is of iron, burned in many places, by a combina- ton of chemicals or from some other agency. The dyke contains no prom inent outcroppings, and at such places as these do occur, there is nothing to indicate the existence of mineral bearing rock to an inexperi- enced eye, and even an ordinarily ex- perienced prospector, would pass it by unnoticed. MT. Munds has had twenty-five years practical experience in mining and prospecting and has also made a study of the subject theoretically, through extensive read ing on geological formations, so far as it pertains to mining, and as stated, after weeks of thorough investigation was able to locate the boundaries of this dyke, a very difficult task, as will be seen by any one looking over the ground, on account of its being cover ed in most places, both by d thick layer of earth as well as by dense growth of brush. A gulch in one place cuts across it and exposes both walls very plainly, as well as expos ing the contents lying between its walls.
 At every point in this gulch, be- tween the well defined walls of the dyke, copper and iron sulphides ex- ist which give fair value in copper and gold, and at different points along the banks of the gulch small openings have been made. from which remarkably rich ore has been taken.
 In prospecting the country on either side of this dyke Messrs. Munds, Kyle and Beach discovered a number of lodges, all of which point ed not only into the dyke, but to a cer- tain central point in it, the lodges so far discovered forming sort of spokes to an immense mineral bearing wheel. The celebrated old U. s. ledge, which has become historical, and which has been yielding such rich ore recently, has been traced clear to this dyke, and Messrs. Munds, Kyle and Beach have located three claims on it be- tween the U. $. claim and the appar- ent center of gravity of the dyke. Other lodges running into the dyke have also been located by them, as well as a number of claims on the dyke itself the number of their loca- tions being sixteen claims in all.
 A company has been incorporated to work the claims, capitalized for Sl, 100000, of which S400,000 has been placed in the treasury for develop, ment purposes. The officers of the company are composed of the follow
 ing well known citizens: w w
