Hallsted Gold Lode Mines
Rich Gulch Project
The Hallsted Gold Mines were staked in the 1870's by Asa Hallsted, and early Plumas County pioneer. The numerous surface gold quartz outcrops were mined by trenches, adits and tunnels that followed the seventy five foot wide disseminated vein structure northwest from Twelve Mile Bar, on the Feather River.
The area of the Hallsted Lodes was overlaid by a quartz gold structure that eroded over time and left free gold in the ravines that surround the mine workings. As stated in the 1892 Report of the State Mineralogist, the area includes "...a rich sprinkling of free gold..." (text of the report is at the bottom of this ad). Numerous gold bearing quartz veins remain outcropping along the length and breadth of the four claims. The area continues to produce gold quartz specimens from the richer pockets of ore. In addition to underground mining, the area can be productively worked with a metal detector, drywasher and Vac-Pak. In the early summer the ravines are workable with a small backpack dredge in the seasonal creeks that carry free gold concentrated in the ravines.
In 1984 these claims were incorporated into the Rich Gulch Project then under development by the Inca Mining Company. They were then designated as Virgilia group claims Rush 2, 4, 6 and 11. These claims were obtained from Inca along with the company drill records by the current owner in 2007.HISTORY
Placer deposits that were discovered at Rich Gulch early in the period of the California Gold Rush were played out by the 1880's. The gold was found to originate in quartz veins beneath the placer workings and underground operations to exploit the vein deposits began about this time. The earliest work was on the Hallsted properties, which covered vein exposures from the present-day Virgilia property northwest through the present-day Central property. During the period 1927-1930, Homestake Mining company conducted a thorough examination of the western Hallsted claims that included mapping, sampling, diamond drilling, opening of closed tunnels, and driving of new drift. A total of 1m032 samples collected from the underground workings during 1929 and 1930 averaged 0.11 ounces per ton gold (with a high of 11 ounces), consistent with historic Mother Lode undergound production. Much of this work was done in the area of present Central orebody.GEOLOGY
The Melones Fault, the main structural feature of the Mother Lode Gold Belt, is located 500 feet west of linear zone of quartz veins that hosts Central and Virgilia orebodies. West of the fault are ancient (Triassic-age) submarine basalts that have been metamorphosed to serpentinites. East of the fault, the rocks consist of marine sediments of the cedar formation. These rocks strike 55 degrees north (thus the orientation of the local mine grid in this direction) and dip 55 degrees east. The cedar formation is also metamorphosed and consists thin bedded slates, a dacitic flow, and minor limestone. The veins are hosted by the dacite flow and the adjacent shales. The dacite ranges from 3 to 80 feet wide and averages 35 feet. Ore-grade widths are primarily in the dacite and range from 10 to over 70 feet. Gold values in the quartz veins are silcified zones are the same from the deepest levels of the Virgilia Mine workings to the highest surface exposures above the Central orebody, a distance of over 2400 feet.
