A former Pb-V-Cu-Ag-Mo-Au occurrence/group of 19 unpatented claims/mine located in the SEΒΌ sec. 28 & in the SWΒΌ sec. 27, T4S, R15E, G&SRM, 1.6 km (1.0 mile) SW of Chilito (historical mining town) and 6.2 km (3.8 miles) NNW of Hayden, and extending from Reagan Camp on the W, up Keystone Gulch and Little Chocolate Canyon to the Schneider Group on the E, about 1ΒΎ miles SW of Chilito ghost town. They are bounded on the north by the Seventy-Nine Lead-Copper Co. claims (79 Mine) and approximately on the south by Chocolate Canyon. Early history is not documented. Mr. Lee Reagan acquired them about 1923 and had an active interest in them until circa 1950. Subsequently owned by the Kullman-McCool Company, Kelvin, Arizona (1953 - ?). Operated by Martin Fishback (1953 - ?). NOTE: Accurate coordinates obtained January, 2007 (adit portal).

A "Barking Spider" in American slang is audible flatulence attributed to a mythical creature. A collector at the site ate beans for lunch!

Mineralization is a polymetallic deposit with an ore body at a width of 4.88 meters and a length of 914.4 meters in streaks and pockets hosted in the Naco Limestone. Naco limestone and a large plug of basalt porphyry crop out over most of the claims. The best mineral showing is along the north contact of the basalt porphyry with Naco limestone. This contact, where exposed in Keystone Gulch, dips steeply north. The thin-bedded Naco Limestone shows mineralization up-dip from the porphyry in a few favorable places. Associated rocks include Pennsylvanian diabase (dolerite) and porphyry. Local rocks include Permian to Pennsylvanian sedimentary rocks.

East of the Keystone fault in Little Chocolate Canyon, prospecting in diabase has disclosed several small veins containing lead and copper minerals.

Local geologic structures include the Keystone Fault.

Workings include surface and underground openings on the south side of Keystone Gulch, Β½ mile east of Reagan Camp, comprised of 6 tunnels with over 5 (sic) feet of drifts, 1 winze at 125 feet deep and 1 shaft at 240 feet deep. Several adits and cross-cuts have been driven at different elevations and to an overall depth of 73.15 meters.

Production has been small and very irregular from several scattered prospects and small workings. Several carloads of oxidized Pb ore were produced and shipped to the El Paso, Texas smelter.
