This is a small district in southeastern Fresno County in the vicinity of the town of Dunlap about 40 miles east of Fresno. Superficial placer mining was done in Mill Creek and other streams during the early days. Small-scale lode mining was done from the 1880s through the 1900s, but little or nothing has been done since.
The area is underlain by granodiorite and related rocks with narrow slate belts. Some limestone lenses and schist are present. A few shallow north-trending veins a few feet thick contain free gold and varying amounts of sulfides. The veins usually are at or near granite-schist contacts. Most of the output has come from the Dixie Queen and White Cross mmes.
