 J. M. Kirkpatrick, owner of the Ragns
 rock property. MT. Kirkpatrick is like
 wise owner of 6 group of claims near sh
 Mexican boundary. He did not locst
 them till certain that they were in Ari2
 ora-after the boundary was establishe'
 last year.
 Years age Mir. Fitzpatrick found in
 house he had purchased, in cavity, sl
 overall pocket with several pieces o
 rich and peculiar ore. He took assyl
 and found them running in value int
 the hundreds of dollar a ton. He sub
 sequently learned that they werI
 brought there by Mexican who hsc
 found them as float, but could noI
 find the leads. For years in going ovel
 the hills Mr. Kirkpatrick sought ort
 similar in nature to the pieces found

 near the border. On the establishment of the border, he located them.
 Some development has been done, but only so far as development shows does he value it. He ard his partner. George Stevens, are getting on in years, and dc not care to work at development ae they would if younger. The ore of the mine is good enough to steal, and the owners | do not care to get it out to be carried away. They have lost some of the rich. est by theft. The assays given in the following run high, but Mr. Kirkpatrick makes the statement that on @ practical working average he believes it would run S25 in gold and 9 ounces in silver. This, If borne out, is very good propos- ition. The following data is furnished by the owner.
 The Last Chance and Boundary Line claims are located on the same vein of mineral bearing quartz, commencing within fifty feet of the boundary line and running northerIy 300 feet. The vein is quite large and we'll defined, run. ming from 2 to 20 feet in width with a dip to the east of about 70 degrees. The formation through which this vein runs is chloride granite with occasion. ally streaks of birdseye porphyry. About 400 feet north of the Sonora line the owHers have sunk a shaft 50 feet deep, commencing on about 3 feet of quartz which has widened out to over eight at the depth of 50 feet. The ore at this point is principally smelting and con- centrating proposition. Assays of over 50 samples from this shaft gives 61 50 ounces in silver ssd s44.10 in gold with 31 per cent lead.
 About 700 feet north of this shaft at point where the vein is cut by canyon at depth of l50 feet from the crop pings on the hills between the shaft and the bottom of the canyon a tunnel was started in the direction of the shaft end nearly on 8 level with the bottom of the canyon. At this point the ore is en- tirely different from the ore in the shaft, and of very high grade. The last shot in the face Of the drift threw out nearly 100 pounds of ore. Three samples of this ore assayed, No. 1 gave silver, 249.10 ounces; gold, s62SOl. No. 7 gave 364.5S ounces silver ano s1004. .86 in gold. No. 3 gave 376.63 ounces silver and slOO486 in gold per ton. The ore at this point is perfectly free milling, horn silver and gold visible to the naked eye all through the ore. 1000 feet further north on the same vein con- siderable work has been done and about 30 tons of ore are piled up. Six samples of ore from this pile of every class gave by assay: No. l gave 28O.50 ounces sllver and s25O.16 gold; No. 2. heavy car bonate, gave 286.8O ounces silver and sl25.6S gold; No. 8 gave s279 ounces silver and s5023 in gold No. 4 gave 1923 ounces silver and S25.11 gold; No. 5, highly sulphuret ore, gave 1855. .94 ounces silver and S125.6S gold; No. 6 gave 82.64 ounces silver and S50.23 gold, all per ton.
 About 600 yards east of the Last Chance mine IS located the 133 mine, 90 named from boundary line monument 133 near which this claim commences, and courses in a no-tharly direction. This vein crops out continually for nearly 800 feet. About 500 feet from the southwest end of this claim an opep- ing has been made and shaft sunk IS feet deep. At this point the vein is split by horse. The ore exposed is 2 | feet wide and there is here 70 tons of ore | on the dump. Twenty samples of all | kinds of ore from this mine gave an av- craze assay of 61.50 ounces in silver and | S66. 80 in gold per ton. There has not | been enough development work done on | his group of mines to determine their | value, but ss prospects they are No. l.
