 The Mineral Creek district is known to have had copper since twenty-two years, but has never been successfully worked. The previous owners of tue presentRay company's ground erected mill on Mineral Creek in order te separate the copper out of the second ary deposits, and tried to concentrate the oxide ores found in the diorite formation. They also erected . smelter at Riverside, but both
 dertakings proved of no commercial success. The difficulty was not only treating the oris, but it is proven that experts were sent out who condemned the ground, being paid by other com panies, in order to recommend their ground. This is proven fact, and perhaps the only factor why Mineral Creek is not an active producer to-day.
 The present Ray Company gave some six months ago a bond to the Globe Mineral Exploration Company, of London, which put force of men on the ground. Considerable explora- tion work has been done, and MT. Hill, the manager of the Exploration com pany, is well satisfied with the results. l As soon as the bond is paid up the Ex- ploration company is going to spend about $l,000,000 in opening up the mines, erecting concentrators, teaching plant and shelter.
 The Exploration company is the same company which opened up the l Iron Mountain mines in Kesnick, Cali fornia, which have paid up to date l $2, ,000 in dividends. The Ray Company owns twenty-seven claims and fourteen claims are patented. On the Ray mine forty-five feet of drift ing into the quartz-porphyry showed 4.6 per cent. concentrating ore in form of sulphides, and the mineralized zone 1 is supposed to be several hundred feet wide. Occasional rich streaks of high grade copper glance are found, ayerag- ing from sixty to seventy per cent. copper. As there is very little iron in the ore the concentrates will run as high as thirty and thirty-fve per cent. copper On the Tribunal claim, tyven- | ty fe ct from the surface, rich sufphio3 ore was encountered. This claim lies about in the center of the district and the showing is remarkable for the 1 little work done. The tunnel is all in ore, and how wide the ore body is pretty hard telling, as there are no cross cuts driven so far to show up the width of the zone.
 About one-fourth of 8 mile north of the Tribunal claim are the claims of Innes' Company, which have sunk 1 on one claim a vertical shaft 4x6, to a depth of 105 feet. With twenty feet depth the ore zone was reached and an average assay was about 4.5 per cent. copper, and with depth the ore has steadily increased in value. At the bottom of the shaft the average ore was 8.5 per cent. copper, with streaks of frst-class ore averaging sixty to seventy per cent. copper. The ore zone on this claim has strong dip towards east, so that the shaft cross cuts the zone with every foot of depth The ore so far is cut for width of l fifty feet, and Mir. Innes is going to sink to 200 feet depth and cross the zone, which seems to have, according to surface showings, width of 400 feet. Above the shaft on the surface the outcroppings are copper stained and show the action of copper sulphate solution. The lower part of country north of Innes' ground shows remark able flow of copper. The whole sur face for depth of ten feet is cemented with copper sulphate solution which was afterwards converted into oxides of copper. Near Mineral Creek, be- tween Innes Company and Ray Com. yany, are located the claims of Chas, Taylor, covering big porphyry zones running from Mineral Creek towards Tribunal claim. The Taylor claims show large quantities of oxide ores and native copper between the claims ric copper flows cover the lower ground between the zones of porphyry. The presence of sulphates can be seen in several shafts sunk on the Monarch claim, but the porphyry seems to have been thoroughly leached so that shafts have to be sunk below water level il order to find the sulphides. A pecu' liar fact was discovered in the bottom of the Ray shaft. Gravel beds found showing that the water level was oncs lower and through erosion the differ. ent crevices were filled up and tht water level was raised.
 \ It is reported that the Taylor proper. ty is under bond to the Globe Mineral Exploration Company. This ground is extremely valuable to 8 big company as it has, besides fine showing of ore, almost the only open place for mil and smelter site. MT. Taylor has done assessment work on his claims for thu last sixteen years and deserves greai
