Rich Gulch Project
The Rich Gulch Project Consists of a conglomeration of lode gold mines that follow the Melones fault northwest from the feather river in Plumas County, California. They were consolidated in 1983 by Inca Mining Company with the intention of developing a large scale mining project. Most were sold off when gold cratered at $275 an ounce.
We purchased the remainder of the project in 2008 from Mauro Berretta, President of the Inca Mining Company. The mines have been since worked small scale with metal detectors, drywashers, high bankers and backpack dredge that uses recycled creek water. As the gold vein structure collapsed over eons there was left a rich sprinkling of free placer gold in the canyons along the claim ridges. Underlying is the disseminated gold vein in quartz structure in the exposed bedrock. There is a large specimen of gold in quartz from these mines held by the California Mining Museum in Sacramento.
Inca Mining Company diamond drilled the Cameron zone in 1983 and determined that the Cameron Zone drill holes were the highest grade to that date as compared to the Virgilia, Erik, Follet, and Central zones. This circumstance was published in the mining community by George Cross as evidenced by the attached copy of his newsletter. Lode mining would be most productive for these claims but dry washing in late summer with use of a Vac-Pak also has proven to be very productive.
Sale includes a copy of the Inca Mining Company geological and engineering report of the property.

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.
