Rich Strike in old Kelly Mine.

h hcliy, IN. w., ulspdUCu says uc Tri-Bullon Smelling and Development company, the present principal produc- ing company of the Kelly camp, own ing and operating the old Kelly mine, has made very important ore strike in the Nit workings. In cross, scouting easterly from the 200-foot level of the and one half miles from the town of Kelly, a body of heavy sulphide ore has been encountered. The Nit claim is located north of the Waldo workings of the Ozark Smelling and Mining company, and the ore body cut by the Nit cross.cut will, it is believed, prove the immense deposit of sulphdes open. ed up by the Waldo tunnel.
 The Waldo tunnel, completed by the Ozark company in 1906, cross cuts the formation for a distance of 100 feet, and was driven to facilitate the extrac- tion of the ores of the Graphic mine,
 
 at the base of the Magdalena range, on the west slope, and at the contact of granite porpnyry on the west and carboniferous limestone on the east, the Waldo crosscut tunnel passes through the upper sedimentaries, whose strata dip to the west at an angle of about B degrees and reaches the basal sedimentaries, known locally as the Kelly limestones, at a depth of approximately 200 feet vertically below the 600 foot level of the Graphic work. ingS. AL this depth, in the lower limestonts S, the tunnel cut the same shoot of ore showing in the lowest lev ct Of the Graphic, and by drifting on and crosscutting in the two silver pipe" ore horizons, north and south from the crOsscut tunnel, and upraisiny on the dip of the strata, for connections with the Graphic workings. an im- mense tonnage of ore was exposed and blocked out for extraction at minimum expense through the Waldo tunnel The deposit on the Waldo level proved to be of unusual thickness, extending in places from the east or main silver pipe hor.ZOn to the west silver pipe horizon, distance of nearly 100 feet, and the tonnage blocked out is suffici- ent to keep l00-ton plant in continu ous operation for many years. The ore contains good values. but is very base in character, consisting of very in. innate association of sulphides of zinc, iron, leal anG copper the first two mentioned metals predominating, mak iny the separation of the minerals complex proposition-on the solution of which latter the Ozark company is now engaged.
 The Nit crosscut cuts the lower or basal sedimentaries at depth of ap- proximately 50 feet below the Waldo tunuel level and several hundred feet north of the limit, as defined by north end line of claim, of the Waldo deposit. Air drills are in operation in the Nit crosscut and though the ore strike was made but recently, over 20 feet of ere, similar in character to the Waldo ore. has been passed through, and there are indications that the eastern limit of the shoot IS near. Thus the great importance and benefit of the new strike to not only the Tr-Bullion and Ozark companies but to the camp in general, can be readily appreciated. Kelly camp has held the record for zinc ore production in both quality and quantity in the territory of New Mex ico for many years, and from the many recent developments in the ore line the camp promises to beat that record for the new state.
 The Tri-Bullon mill, com mbination wet-magnetic concentration plant with capacity of about 100 tons per "A hours, continues in daily operation, as it has since early in January, 1910, treating sulphide ores from the lower workings of the Kelly mine. Preparations are being made to treat the sulphide ore recently encountered in the upper, No. 2, workings of the Kelly. This latter ore was exposed by the last lessee, Mr. c. T. Brown, who had two-year lease for the extraction of the oxidized ores above the No. level; during the life of the lease MT. Brown shipped thou sands of tons of zinc carbonate ore,
