district has been Assured, tdulted and crushed so frequently in its geological history that sulphides are sometimes found on top of this leached ground. with oxides between and in almost all other conceivable positions. As a re- suit. the search for ore is one that must be kept up constantly and no area can safely be left uneXplored.
 Calumet 6 Pittsburg's property has been opened less extensively than any of the others. Its shafts developed a tremendous flow of water which pre- vented the immediate extension of drifts. big pumps were installed and what was apparently a sort of under ground lake or drainage basin has now been pumped nearly dry. The flow of water is much smaller than iJ was while ago, and exploratory work is un- derway. The Briggs SlafC IS 1,I50 and the HCatson 1,1FG feet deep. Drifts from the 975 and 1.09O-fUot levels of the former have developed good bunch Of ore. This shalt is connected through to the Junction wOTkip Ss. Drifts from the 900 and i,00lfC0t ley els of the Junction into the Calumet & PittsGurg territory haze also doVGl- oped some ore in the CTmOni claim.
 It seems to De th1 COncsnSus of opinion among the gcologIsGs who have made Q study Uf the diStric- that the Calumet x Pittsburg's property is exceptionally well located. This ol .n~ ion is gaining strong confirmation in tSe recent development work. On my last visit to the proDerEy it's waste piles showed as mucn and as deeply colored leached material as those around the most productive shafts of the Calumet & AriE0la and Copper Queen, and assays indicated that an other CTe body. her )fre undiscov"rC :, was being approached.
 Lake Superior & Pitsbrrg's eXtcn- sive property IS i:l part located tS.! ther away from Sacramento Hill tDdn the others in this group. As this hill is commonly understood to be the source of naturalization, the develop ments in the extreme portion of the property will be watched with interest. Included in the Lake Superior & Pitts burg holdings IS the old South Bisbee property which was worked many years ago, carbonate ores being taken from a surface cropping. This and the scene of the Copper Queens original workings were the only outcrops in the entire district.
 NO Bt DOulco Ol OIc NnO smaller ones have been developed in the Lake Superior & Ptttsburg. Its north ore body is opened 125 feet long and 50 fet wide in beautiful car bonates and oxides running from 5 per cent to. 30 per cent copper and averaging l5 per cent to IS per cent. Crushing ground has temporarily cut down the production from this source. Its south ore body is 300 feet long and equally wide, but more or less waste and lime boulders are iptermixed with it. The richest showing Is on the 1,100-foot level. A drift 400 feet long, driven from a raise, is also mostly in ore. This body is in the South Bisbee and Iron Cap claims. It yields s per cent to If per cent ore. There are also two very god ore bodies in the Jessie and Glencairn claims. AS large pro portion of all its drifts are in leached ground, it is to be expected that other ore bodies will soon be developed.
 The company's two principal shafts, the Cole and No. 3, are 1000 and 1,200 feet deep. It has a third shaft which is idle. About 200 tons of its ores are going to the Calumet & Arizona smelt- CT daily for treatment and it's opera tions are already returning a fair net profit.
 Pittsburg 6 Duluth's shaft is down 1850 feet, nearly all its development work has been confined to the Sunny side claim. It has a large body of sulrhide ore on the 1,350-foot level, ard has developed some oxides in a raise to and drift on the 1270-foot level. This ore body, altogether, is 250 feet long, 250 feet wide and 150 feet in thickness, or depth. What is a branch of the same or another ore body has been encountered in a drift about 1H0 feet distant. The develop ment work shows it to be 125 feet long.
 The company is putting out about 106 tons of suiphide ore daily now through the Lake Superior 6 Pitts burg's shaft. Its ore is comparative ly low grade, yielding an average of about 2 per cent copper. Because of it's excess of iron and sulphur, how ever, the company receives premium on this ore and Is said to be making good net earnings.
 There is reason for the belief that the exploratory work of the PittsbuTg & Duluth has been conducted at too great a depth and that the drifts are below the ere horizon. IL is probable that the drifts will be extended from higher levels soon, and that the prop teTJy will be extensively explored. There are surface and other indica- tions which eicourage the belief that some Of inc claims will develop big and rich ore bodies.
