throughout. Between the north and the south ends are many of the best producers of copper -silver-gold ore in the west.
 While some of the best mining men have been holding back from going into this Yavapai schist ore forma- tion because the depth of the ore de- posits was undetermined, it is now proven beyond question that the ore bodies from Jerome to the Kay mine at least, are permanent and become larger and better in grade with depth and the ore that is mined is of such mineral character that it can be cas- fly handled by the oil flotation pro- cess in the most simple form.
 Jerome and Verde District
 JEROME, Ariz, June 1.-Develop- ment activities in the Verde district continue without abatement and have been given additional stimulus by the strike recently made in the southern end of the district on the holdings of the Verde Squaw Copper Mining Co.
 On Wednesday May 15, word was brought in from that camp that the Barter tunnel had broken into a body of good looking ore. Investigation proved that the tunnel had pene- trated a footwall of diorite into a ledge of schist. monzonite and quartz and that 20 feet had been driven in this formation without any signs Of approach to the hanging wall. Chal- copyrite and bornite can he discerned shot through the ledge matter while about six feet appear to be a we'll mineralized ore shoot from which picked samples assayed as high as thirty three per cent copper, several ounces in silver and a trace in gold. However, the ore body, which runs quite high in silica, for the most part appears to be low grade and future | development only can determine it's area and value.
 Jerome Verde
 Diamond drill operations on the 1045 level of the Columbia shaft work | ings at Jerome Verde are disclosing some very favorable conditions. In 1 bore which was run northerly from the northeast drift, some sixteen feet of well -mineralized ground very heavy in iron sulphides, and through which there coursed many small stringers of quartz, was passed through at a dis tance of 400 feet from the set-up. Although this showing is considered of much importance, it is not such as
 
 It is probable that later on lateral prospecting will be prosecuted in this ground.
 | The connection between the Colum- bia shaft workings and the northwest ground of Jerome Verde was effected the latter part of last week, and, when the grades are made to conform and the raise on the 900 level finished, it will be possible for the company to handle the ore from the Maintop claim via the long shaft and west crosscut and up to the surface through the Columbia shaft.
 Verde Combination
 Speedy progress is being made in the sinking of the shaft at Verde Combination and a depth of 9S2 feet had been attained on Monday, May 20. The formation in the bottom of the shaft is very favorable, being a soft blue schist carrying much iron pyrites and some chalcopyrite.
 When the 1000 level is reached and the station cut, crosscut will be run to intersect the quartz ledge exposed on the TOO level and dipping toward the shaft. This ledge, although show ing some naturalization in the form of copper, was a. leached formation l ally lead to the point where intense naturalization will obtain.
 Pittsburgh Jerome
 Seven headings in all are now be- ing run in Pittsburgh Jerome ground two on the 800 and five on the 900 level. On the 500 they are still look ing for the ledge of ore which was recently cut off by a slip in the for nation. However, Supt. Arata has ordered a stoping machine and wher the same arrives will start raise or the ore at the point where the miner aliZation was more intense and iron which samples assayed as high as seventeen and one-half per cent.
 Calumet & Jerome
 | The long south cross cut at the Calumet and Jerome has now pene- trated a distance of over 1900 fee from the bottom of the 600-foot shat and the face of the heading is in { green schist with stringers of quart; running through it. The ground i: quite soft and shows some oxidization naturalization occurring in the forn of iron pyrites and chalcopyrite.
 The crosscut being driven easterl, toward the north and south fault i still in a muchly sheared zone witt l nation.
 Green Monster
 Development work is being prose cuted at Green Monster only in tn Dorothy May shaft and In the Gorg tunnel. The former has attained depth of 560 feet and is bottomed il a hard diorite. The crosscut from tn bottom of the 100-foot winze in tn Gorge tunnel is in 94 feet, and whil the formation is good looking quart porphyry no naturalization is to b observed.
 Grand Island
 On account of lack of capacity | drill to a greater depth the diamon drill bore was stopped at 90S fec without having cut the ledge whic was exposed on the POS foot leve Another bore will be drilled from F different angle. In the meantime tn compressor has been repaired and , is the intention to at once begin tn deepening of the shaft.
 Dundee Arizona
 The water in the shaft has now re ceded to 30 feet below the 450-fot station. probably due to the drain ! age afforded by the Texas shaft poI tion of the United Verde Extensio f extraction tunnel from which ovt ! 400 gallons of water are being pumpe . per minute. It is possible that whe ? the tunnel reaches a point opposit f the Dundee shaft it will afford con g plete drainage for the same to dept . of 900 feet. In the meantime u Dundee is idle except for a sma f amount of prospecting being done c the reef from which the ore shil I ments have been made inthe past. t Jerome Superior e The large 80 horse power hoist hf t arrived and has been installed so tn; g sinking from now should progre:
