From Skyway drive in Magalia, shortly past De Sabla, left on Powellton Rd which is not paved. Stay left at fork on Understock Rd which becomes Doe Mill Road. Follow Doe Mill down to the river where there is a bridge. This is Butte Creek Forks Rec area. The road is rugged, rocky and rutted almost need a 4x4. This area does get snow in winter. The Rec area is just a bridge. No facilities and little parking. There is a trail going upriver that you could take a backpack of gear. The water level was very low and according to a local friend the river was much slower than normal. So, this would be a good time of year to go. Did not see any mining activity, but lots of promising geology and river bank. A quad or hiking would be needed to go to campsites from Kolar road which is just a dirt path off Doe Mill after the bridge.
