FINAL GROUP
 EXAMINATION 'Of RGnfPO Claims In Dripping
 Springs Range FAVORABLE SIT LAYTON
The Wealth of the Ore and Its Locality All Give Prom ise of a Mine of Which Much More Will be Heard In the Future.

Kelvin. Oct. 22.--(Special Corre- | spondence of The Republican, )--Hav- | ing received numerous inquiries from | people in all parts of the country in | reference to the valuable Renfro group of claims in the Dripping Spring | range of mountains. a special visit was | deemed advisable by the mining re- porter of this locality to submit full | report to the interested public 'on this
 rich property.
 Having arrived at the Renfro camp, located a short distance from Copper Canon, our horses were picketed and Mir. Renfro stated that he was at our 1 services.
 The Renfro consistes of 24 claims | bounded on the north by Copper Can
 on. and running south to the summit of the Dripping Spring range, and
 bordering on Dipping Spring wash on ! the east, running west some 4000 feet.
 This belt os mineral has been traced | through to the valuable Christmas | property. several miles away. The | Pinal mountains are several miles north and are to be plainly seen from | the camp. To the Phoenix and Eastern
 railroad through Troy, 1t is seven miles and a good downhill road the entire distance.
 A POSSIBLE RAILROAD. It might be mentioned here that General Manager Epes Randolph of the Arizona division of the Southern Pacific has in contemplation a railroad
 to be run up Dripping Spring wash from the Phoenix and Eastern railroad on the banks of the Gila river, to the | head of Mineral Creek. thus passing
 within 1000 feet of the Renfro prop erty, thence to Kelvin, thus encircling
 one of the greatest mineral belts in
 the country. Such mines as the Win
 kIeman properties. the London Arizona
 the Two Twins, Christmas. Renfro, ] The Ray Consolidated. Kelvin Calu
 met company, Arizona Hercules and
 many other valuable properties will
 be greatly benefited by it. Plans and
 surveys have been made for this pro-
 ject and in a short time we can look
 for the commencement of this great
 undertaking.
 DESCRIPTION OF THE RENFo. | Coming back to the Renfro property
 it lies in a formation of porphyry, lime, diabase and layers of duartzite and
 the Assures cut through all these
 formations; the sedimentary forma-
 ton being very deep. Locations have
 been made on parallel tissue veins
 about 600 feet apart There are also
 many intervening Assures, thus rib
 ping the entire mountain. These fis-
 sures have been thoroughly and sys- tematically studied by Mir Renfro and he feels safe in saying that they all 1 lead to vast deposit of copper ore in | depth. Bedding planes connect all | these Assures. These bedding planes occur from a solution of copper being | forced up the Assures and escaping in
 a soft sedimentary formation each side of the Assures, consequently forming large bodies of copper. Where
 bedding planes occur near the surface. | they continue on at various depths,
 some of them being but eight feet apart, as may be easily seen on the Roman Eagle claim. These deposits
 of copper occur, one below the other in any place where the solution of cop
 per can find an outlet in the soft sed- | imentary formation and is held in de- pOsit by ribs of a harder formation.
 Faults from 100 to 400 feet displace-
 ment are plainly visible on these fis-
 sures. These faults are the entire 1 length of the veins which proves con- l clusively that they are true Assure veins. The veins average in width | from 4 to 125 feet between walls and are mostly contact veins. From an
 estimate made by a mining engineer water level will occur at 400 below the
 surface and when water is encounter
 ed the oxidized and other different
 characters of ore change to sulphides THE WORK DONE.
 Considerable development work has
 been done on this property. Locations
 have been made on all the Assures as stated above. but the majority of the
 work has been done on the Roman
 Eagle, which is located near the center l of this group and in which a large fault occurs. Tunnels have been run
 in the Roman Eagle 200 feet from the
 surface striking good shipping ore also at 400 feet from surface, striking good | shOwings. The ore in one place is 40 | feet in width on the Roman Eagle
 claim running north from the Assure indefinitely on a hard bedding plane
 of lime. On the dump of the Roman [ Eagle are 30 tons of a good class of | ore that will average about 10 per cent
 also on the dump are 500 tons of ore 1 that will average ? per cent jand in | the mine proper is ten times the l amount of ore before mentioned block | ed out which will average high class. ! Mir Pa~fro has bper working most of
