 The Lake Superior & Pittsburg mine
 has passed through the splendid ors
 body which was encountered a few
 weeks ago and is now entering an
 other, having penetrated it about ter
 feet. The indications for this prop
 erty are constantly improving. and il is now looking splendidly The ore
 bodies so far opened up in this mine
 as well as in the Calumet & Pitts
 burg are insufficiently explored to
 make any reasonable calculation as to their extent, or the precise connec-
 tion or relation they bear, one to an
 other. Much cross-cutting. sinking
 in the nineralized ground, extension Of drifts and other openings will be re. quired to arrive at a fairly definite knowledge of the ore reserves, But enough has been shown up to give
 a fair idea of what copper mines
 of the Warren district are able to
 demonstrate.
 The ore body through which the L. S. & P. has just passed was en- countere6 in the southern drift from the 1,000-foot level at point 500 feet from No 2shaft The drift passed
 through 130 feet of ore before coming out into he unproductive material again. Of this 130 feet, 115 feet was high grade ore, while the remainder was of a very profitable character. The drift then passed through 50 feet of lime and iron and is TOW into another ore body for a distance of 10 feet. i This alter runs 34 per cent copper In he enter of the 130 feet of ore through which the drift passed a short time ago, a crosscut has been driven east 45 feet and has come out at that point into leached formation. A crosscut is being driven west a couple of sets of timbers, out of the way of transportation through the drift. and from that point winze will be sunk 70 an indefinite depth below the 1.OOO feet level This winze will be about 900 feet from No. shaft.
 Important Geological Development There remains 2,200 feet of unopen- ed ground between the breast of the drift from No. 2 shaft to reach No. 3 ir;f. north ward in No. shaft short time ago at a depCh which corresponds with the 1 l.00O-foot level of No. 2, and a de velopmant which adds much to- the geological knowledge of the district has just occurred therein. This is the opening of a quartzite reef. which is assumed to be identical with the quartzite contact that eucircles DOT tion of the high ground around Bis bee. The nearest point at which this quartzite shows on the surface is about 5000 feet from No. IL. $. & P. and it's course is such as to lead 10 the belief that the newly opened formation at depth is the same one. Some believe that the impenetrable qualities vf this reef are accountable fer the massing of the extremely large and rich ere bodies, of which the ground now being opened by the l.. s. & p. is typical, and that the very highly mineralized ground now being developed by the c. & A. sisterhood will be found to lie within this encom- passing line. This, of course, at best is nothing more than a theory, and can be proved or disproved only be exploration. The likelihood is very strong. nevertheless, that good ore values will continue southward in the l. S. & P. until the quartzite reef is encountered.
 The north drift from the 1000 foot level, going in the direction opposite to that in which the recent good strikes have occurred, is now in 700 feet and a crosscut being driven from that point is in good ore. It is not as favorable as the other drifts, il is true, nor is that to be expected: but it is looking very good. indeed with a profitable percentage of copper.
 No shaft is now sunk to a depth HOO feet, of 100 feet below the level at which ihe extensive and successful drifts ire opening up so favorably. At the 1,1O0-foot level 400 feet of drift ing has been carried forward, 200 fleet north and 200 feet south from the shaft. These drifts are in the most favorable kind of soft formation, with much water, and all indications are
