About this location
The Victor Mine (also recorded as the Big Buck mine or Big Buck prospect) is a historic gem pegmatite working on Mack Ridge at the southwest base of Rincon Mountain, in the Rincon Mining District of San Diego County — the same pegmatite belt that produced the famous Pala district mines a few miles north. It sits roughly two miles southeast of the community of Rincon, bounded by the San Luis Rey River. The mine worked a granite pegmatite dike and produced tourmaline in a range of colors (pink, blue, violet, green, colorless, and black), along with lepidolite, spinel, and garnet. This is a real, documented locality with genuine mineralogical significance, but it is a small historic mine working, not a maintained public collecting site — current land status and whether the workings are open to visitors is unverified. Treat this as a lead for further research, not a confirmed dig destination.
Always seek permission where required, follow local laws, and practice Leave No Trace. Locations and details are community-submitted and may be inaccurate. Not sure what's legal here? Read our full guide to rockhounding laws by land type.
Found Here
- Tourmaline — the mine's signature find, in pink (rubellite), blue, violet, green, colorless (achroite), and black varieties, some in radiating aggregates within lepidolite. UNVERIFIED how much surface material remains findable today.
- Lepidolite — lithium mica, host rock for much of the tourmaline.
- Albite and orthoclase — feldspars typical of the pegmatite matrix.
- Cookeite — lithium clay mineral commonly associated with lepidolite pegmatites in this district; DB-listed but not independently confirmed for this specific mine.
- Bismuth — the district source describes bismite (an oxidized bismuth mineral) rather than native bismuth; treat the exact bismuth mineral species as UNVERIFIED.
Difficulty
Getting there
The mine is on Mack Ridge near the community of Rincon, San Diego County, along the San Luis Rey River. UNVERIFIED: specific road access, current trail or gate status. Given the terrain (a ridge above a river canyon), expect unpaved roads and possible high-clearance requirements — confirm before attempting to drive in.
Collecting here
This is a hard-rock pegmatite working, not a surface float site — historically it required digging into dike material and old mine dumps. UNVERIFIED: whether any collecting, surface or otherwise, is currently permitted. San Diego County's gem pegmatite mines are largely on patented private claims, and many in this belt (including the well-known Pala district mines) require paid access, club permission, or are closed entirely. Assume the same may apply here until confirmed otherwise.
Know before you go
Land status for the Victor Mine is UNVERIFIED — confirm ownership and permission before visiting. San Diego County's pegmatite belt is a mix of BLM, tribal, and private patented claims, and the Rincon Mining District sits near the Rincon Band of Luiseño Indians reservation lands, so boundary confirmation matters here specifically. Do not assume public access just because the mine appears on older mining maps.
