Josephine County - Greenback Area 115 Equipment: A small ball mill operated by a 2{ h.p. gas motor. Geology: Diorite and greenstone country rock abutting against serpentine on three sides. Gold is mainly in the quartz: although there is some in tho country rock, A small quantity of sulfides occur in the quartz, and a loss amount in the country rock . According to Mr. Reed the big vein will average $3 - $15 per ton for 15 to 40 feet of width. Informant: R. E. Reed, 4/4/40. Report by: Ray C, Troasher. 7 ROGUE RIVER GOLD COMPANY Greenback area Owner: Rogue River Gold Co., D. H. Ferry, Rogue River, Oregon, vice presLdent and manager. Location: On Grave Creek upstream from Leland in secs. 9 & 10, T. 34 s., R. 6 W. History: The dredge was moved from its original location on Foots Creek, and began digging on September 25, 1935. Operation was discontinued in 1939 and later the dredge was dis mantled and moved to Idaho. Equipment: The dredge was a connected bucket type having a daily capacity of 8000 cubic yards. It was powered by 15 motors aggregating 700 h.p. Average daily employment was 40 men. General: An old channel of Grave Creek south of the present stream was dredged, Settling basins were constructed to settle mining mud, Work upstream was halted as bedrock became so deep it was impossible to clean bed rock. Informant: Grants Pass Courier, January 27, 1937. SHOT MINE (gold) Greenback area Also known as Dutch Girl ~: IHll c. Smit)l, Box 421, Grants Pass, Oregon. Location: On St. Peter Mt, in the NW¾- sec. 33, T, 33 s. , R. 5 IY, Surface workings are on the Forest Service King Uountuin road about 7 miles from u. s. Highway No. 99, History: The property has been worked for about 50 years, starting .about the same time as the Greenback Mine. Some of the ore was treated in an arrastra. Recently ore was treated at the Dale Prow mill, Development: There are three tunnels containing underground work as follows: One is 200 feet long oontaining a raise 100 feet in length starting at a point 150 feet from the ~ortal. The second tunnel is 258 feet long containing one raise now caved. The third tunnel is 180 feet long; the portal is now caved, Geology: Country rock is gabbro and quartz diorite. There are three quartz veins roughly parallel included in a distance of 120 feet, One vein averages about 12 inches in width, trends east-west and dips 70° N. It has greenstone footwall and qunrtz diorite hanging wall, both walla showing gouge. This vein is lenticular and ranges up to 2 feet in width. Average •alue is reported to be $40 per ton, Gold is both free nnd in combination with the sulphides galena and pyrite, the latter occurring in small cubes. 0 A north-south vein dipping 40 W, has not yet been explored by underground work. It is ~eported to assay about the same as the east-west vein mentioned above. !!!,tormant: Will C, Smith and Alex ~atts, July 5, 1940. a7 -..a..;;...:b._r: Ray C. Treashor. TABLE 1 .
