 Depth of B,.tter Than 1925 Feet.
 At the Calumet office of the Calumet & Arizona Mining company, samples of the copper glance encountered re- gently in the 750-foot level of the Irish Mag shaft have been received. Their appearance indicates a highly favora- ble condition in the development of this shaft. Copper glance, as is gen .erally known, runs from 75 to so per cent refined copper. The association Of a small amount of oxidiZed copper ore in the form of carbonates with the copper glance now being developed on the 750-foot level of the Irish Mag, will prevent it's running above proba- bly 75 per cent.
 The latest aoyices from the proper ty state that the copper glance ore body has been penetrated for a dis cal explorations have been made, and the end of the deposit is entirely un- known beyond the 3O-foot drift which has been driven into it. Practically the same character of ore. with a sprinkling of oxidized material. has prevailed throughout the entire dis tance so far opened.
 The same character of ore, and very probably the same body. was disclos- ed in the S50-fOOt level at a depth be- low the present development. but at that point the deposit showed only about four feet in width. It was sur rounded. however. by an extensive body of good oxid.zed ore. of a lower grade than the copper glance but car rying very good copper values. Before entering the body of copper glance ore on the 750-foot level, a quantity of this OXiCized ore was encountered. though Of less volume than at the point 100 feet deeper. The new development on the 750-foot level of the Irish Mag is of great importance to the Calumet & AriZona property.
 In the Oliver shat of the Calumet & AT.ZOna, the sulphide ore body. which was reported in The Mining Gazette three weeks ago as having been en- countered on the 1.OOO-foot level. con- tinues as development is being ex- tended. It has now been penetrate5 for a distance of about 35 feet and av- erases 16 per cent or better in copper. This deposit IS in the Senator claim.
 NICE GROUND IN p. & D.
 Some nice looking ground has been encountered from the No. 25 ccosscut of the Pttsburg & Duluth property. This is at depth corresponding to the S50foot level of the hIsh Mag shaft The development has been in a leached ore of very promising char actsr. The strike was mace in a winze which was being sunk from No. 9 cTosscut.
 The Pittsburg & Duluth has started d drift from the bottom of it's shaft which corresponds in depth 10 the 1, 050-fOot level of the Irish Mag shaft. This drift will connect with No. ? .crosscut running toward the shaft from the 1,00-foot level of the Lake Superior & Pittsburg The Pittsburg & Duluth continues to open ground on the crift running from the 1.OOO-foot level Of No. shaft from the Lake Superior & Pittsburg. There are no new developments to be announced, however.
 The Lake Superior & Pittsburg is still engaged in stripping down No. 2 shaft. and enlarging it to dimensions which will make it fit for permanent operation. This will consume proba- bly four or five months more. The Su- peIlcr x Pittsburg, has for the present pf <g of it's opening into new ground. Its underground operations now consist for the most part of openings of points from which the permanent operations that are planned for the coming year may be conducted more advantageous ly. In short, it is conducting those preliminary operations which are nee essary for the economical winning of the ore when regular production be- gins. This work is all being carried on through No shaft. on account of the enlarging which is under way in No. ? shaft
 The Calumet 6 Pittsburg continues pumping and sinking. It has now at tained a depth of 1925 feet. The water is very heavy in this shaft but the pumps now in operation have the ca pacity to keep it out of the way sui ficiently to allow sinking to progrss. The work is rather slow but it is be- ing carried forward as rapidly as pos sible. The Junction is installing Q pump in order to meet the water prob lem, which for the present. is absorb ing all the attention on this property. The pump will be in operation p1oba- bIv within a unonfh -Iiniro Caze4fa
