Tijeras Canyon
Deposit type & geology
Gold-bearing quartz lenses/veins associated with Precambrian mineralization, possibly reactivated in younger structures.
Precambrian crystalline rocks of the southern Sandia Mountains/Tijeras Canyon area.
Age: Precambrian host; vein age not independently confirmed this session.
Structural geology & terrain
Vein/structure orientation: Mostly N-trending high-angle faults, subordinate older NE set
Named controlling structure: No single named master fault; the Sevilleta Metarhyolite is the most favorable host rock
Elevation range: 5,600–7,000 ft (canyon floor; upland parts of the district are higher, unquantified)
Canyon cut through Precambrian gneiss/schist capped by Pennsylvanian limestone; part of the district was militarily restricted/inaccessible after 1959.
High-resolution terrain
~6 m/pixel lidar-derived hillshade (USGS 3DEP) — fine enough to reveal old mine workings, waste-rock piles, trenches, and roads the statewide terrain layer can’t show.
Historical production
34,488 oz lode gold through 1959 (Koschmann & Bergendahl 1968, USGS Professional Paper 610, via USGS Bulletin 1348) — a genuinely significant total that's easy to overlook, since the area today reads as Albuquerque commuter/exurban country rather than mining country.

Current status
Historic lode producer; current status not independently verified this session — this entry has less research depth than most others on this map and should be treated as a flagged gap for follow-up, not a fully vetted profile.
Recency not verified
Current claim/permit status was not independently researched this session — flagged for follow-up rather than assumed dormant.
Land ownership & directions
Land ownership for this district was not independently confirmed in this session's research — verify directly before relying on it.
Not independently confirmed — Cibola National Forest and private/exurban land are both present in the broader Tijeras Canyon area. Tijeras Canyon, I-40 corridor east of Albuquerque.

This pin is a generalized district/historic-site reference point, not a surveyed claim boundary — routes may cross private or patented inholdings where public access isn’t guaranteed even if a road reaches the site. Backcountry mine areas commonly have unmarked shafts, unstable ground, and no cell service; confirm current access and safety conditions (land manager, county, or landowner) before heading out.
Tailings reprocessing potential
Historic processing method not established in the sources reviewed this session, despite real, quantified production (34,488 oz).
This is a documentary heuristic, not assay data.The tier above is inferred from historic production era, processing method, and ore character already cited elsewhere on this page — nobody has sampled or assayed this district’s tailings as part of this research. Actual recoverable gold content can only be established by physical sampling.
Reprocessing tailings is regulated mining. Disturbing or reprocessing historic mill waste requires the same NM Mining Act permitting as new mining (see the regulatory companion guide), regardless of who currently holds the claim or surface rights — and ownership of the tailings material itself is a separate legal question from mineral rights on the underlying land.
Legacy tailings can be hazardous. Pre-modern processing commonly used mercury (amalgamation) or cyanide (heap leach), and can carry elevated arsenic and other heavy metals — not a casual sampling target, and disturbing contaminated material can carry real environmental liability.
Geologist’s read
The single most surprising find in this completeness pass: a mid-size, well-documented gold producer sitting almost inside the Albuquerque metro area, with no placer counterpart and none of the ghost-town profile most of this map's districts have. Flagged for deeper research before relying on it.
