South Hubbard, Banner, Banner District, San Diego Co., California, USA

A former Au mine located 0. 6 miles S of Banner in NE1/4 SEC 10 T13S R4E SBM.

It was located in 1870 just after the Redman mine and the work started in 1874. It was jointly operated with the North Hubbard, Redman and Ready Relief mine. Together they were one of the largest mining operations in the Julian district.

The workings comprise a crosscutting adit, 300 feet long, striking NW, with 2 drifts 90 feet SW and 400 feet NW, plus a 275 feet shaft connecting to the surface. Due to this shaft the mine was always well vented.
One drift connects to the Ready Relief Mine.
The vein, about 1 feet wide, is about 200 feet below the surface

Remarkable are the rolls of gangue quartz found in this and other mines around Banner. The ore was called blue ribbon quartz. The rocks are highly siliceous mica schist (Julian schist).

The mine entrances are located at N33.06001 W116.55087 (accessible adit) and N33.06131 W116.55187 (inclined shaft).

This mine is home to a colony of rare Townsend’s big-eared bats (Corynorhinus townsendii).

This species is very sensitive to human disturbance and therefore the mine should not be entered during the breeding season from May to September.
