GOOD COPPER IS SHOWING IN
 kEWEENAW
For Extent of Opening Work Accomplished Few Mines
 in Lake Superior Dist, Have Ever Made Better Showing,

Special Correspondence to Reivew)
 CALUMET, Mich, April 19.-An eA- cellent copper showing is in evidence in the Keweenaw Copper company's No. 1 shaft on the Medora property in Keweenaw county. In fact for the extent of opening work accomplished, few mines in the Lake Superior dis trict have ever made a better show ing. A representative of the Bisbee Daily Review visited the property few days ago and thoroughly ex' amined the workings. The prospects for the development of a large and highly successful mine are bright.
 No. 1 shaft on the Medora prop erty is sinking on a dip of twenty four degrees, the lode being somewhat flat, and is seven by eighteen feet inside of the timbeTs. 1t contains three compartments, two being 6 1-2 by ' feet each, for hoisting, and the other is ? 1-34 by feet, in the center, for the ladderway The shaft is cribbed above the ledge with four teen-inch square timbers. Sinking is now under way below the 500-foot level and the shaft is bottomed in the richest rock thus far opened.
 Main levels are being opened at 2C5 and 375 feet respectively and owing to the flatness of the lode it is planned to open sub-levels at points midway between the main levels. Drifting east on the first main level. <t a depth of 225 feet from surface has progressed 200 feet. At that point the drift broke into an old adit that was driven in a southerly direction geo feet on a Assure vein made years ago, when the property was worked by its former owners. A good current of air is obtained through the old adit, which greatly improve the atmosphere in the shaft and ventilates the connecting work ings.
 The drift on the 225-foot level to the west is in distance of 200 feet. At a point 175 feet from the shaft the lode was thrown out of its regu-, lar course by a Assure vein inter- secting it at that point. It Is plan ned to start drift there, following the direction taken by the lode and it is expected that the formation will return to its normal course at some little distance farther on. Both the east and west drifts show good cop per rock for the greater part of their length.
 At the 3O0-foot level a station has been cut preparatory to the starting of drifts there, this point being a sub level At a depth of 375 feet the se.~
 I,a, 3nlI f.t a1 The east drift is in sixty-five feet and the west drift has progressed seventy feet. Excellent copper rock has been encountered in the openings on each side of the shaft. At depth of 450 feet from surface sub-level has been established and drifting on the lode has progressed twenty-five feet in each direction from the snaIt.
 The 500-foot level, which will form the third main level, was reached only a short time ago and drifting at that point has not been carried for ward very far, but will be well under way in a short time. The lode is we'll impregnated with copper and is richer than where exposed in the openings nearer surface. Captain Thomas Hoatson of Calumet, who is managing director for the Keweenaw company and general manager of its operations, is very enthusiastic over the showing in the deepest openings, and Captain Hoatson is qualified to judge copper rock, having spent the greater part of his life in the Calumet & Hecla mine.
 The Medora lode averages about ten feet wide near the surface but it widened to fifteen feet at the 225- foot level and will probably average fourteen or sixteen feet in width in the bottom workings. It furnishes an excellent stamp rock, the main DOT ton of the lode being a soft, dark brown amygdaloid, with some calcite, quartz and phrenite, fine copper being freely disseminated through it Some mass copper is found in this portion of the lode The formation is es- peciaIly well charged with copper for about two or three feet from the foot wall, where it has darker color, and contains considerable heavy copper or barrel work.
 At point in the shaft 240 feet from the surface, the lode was thrown about eight feet into the hanging by a crossing This brought the richer portion or foct-wall side, into the hanging of the shaft. At greater depth, however. the lode dropped back to it's normal position. The shaft on the Medora property is well equipped, the surface plant compris- ing the following buildings. substaI.- tial1y built combined boiler and en- zine house, shaft house, supply house, dry house, machine shop, blacksmith shop and a powder house The hoist
