| Basis for focus area |
Tungsten and Be resources at Victorio; REE, Re, W, and Sn are potential byproducts. The focus area encompasses of the Victorio resource. District boundaries for focus area used by McLemore (2017). |
| Identified resources |
Identified resources of beryllium, molybdenum, and tungsten; historical production of beryllium, copper, gold, lead, silver, tungsten, and zinc. |
| Production |
Production from the Victorio district in 1942 was 20,000 lbs at 1% WO3 and 39,200 lbs at 0.6% WO3 (Richter and Lawrence, 1983; Dale and McKinney, 1959). Cumulative production from the district includes 70,000 to 130,000 tons Pb, Ag, Au, Zn, and Cu ore (Hendrickson, 1977). |
| Status |
Past mining. Reserves development for Victorio Mountain Extension by Donegan Resources. |
| Estimated resources |
Beryllium: Resource of 11.9 million metric tons, grade of 0.023% BeO, and grade of 0.01% Be (Foley, Jaskula, Kimball and Schulte, 2017). Tungsten and molybdenum: Victorio Measured, Indicated, and Inferred resources: 154 Mt @ 0.08% Mo and 0.088% WO3 (Knudsen and Hahn, 2012), or 57.7 million short tons of 0.129% Mo and 0.142% WO3 (Bell, 1983). |
| Geologic maps |
Thorman and Drewes (1981), scale 1:24,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
Limestones surrounding granitic porphyry with disseminated and replacement bodies of Mo and W +/- Be. |
| Deposits |
Irish Rose mine (MRDS dep_id: 10009984), Victorio district (MRDS dep_id: 60001677; USMIN Site_ID: NM00037). |
| Evidence from mineral occurrences |
MRDS; USMIN; Foley, Jaskula, Piatak and Schulte (2017). |
| Geochemical evidence |
Donahue (2002) gives high Be in reanalyzed NURE stream sediment data (2-9 ppm). Average grade of vein ore at the Irish Rose mine ore was 0.1% WO3 with 0.6% BeO. |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
More and Stryhas (2007a); Knudsen and Hahn (2012). |
| Comments |
Deposit types in this focus area also include carbonate-hosted epithermal Be; could be remapped, need to focus on tying carbonate-hosted deposits to porphyry (drill core at NMBGMR). |
| Cover thickness and description |
Skarn deposits at surface, porphyry at approximately 2000 feet depth. |

| New data needs |
Alteration mapping. Aeromagnetic and radiometric surveys. Incorporating the drill information and core at the NMBGMR. |
| Geologic mapping and modeling needs |
Although a published map (Thorman and Drewes, 1981) is available, alteration and mineral deposits are not included on the map. A more detailed alteration and mineralization map is needed. |
| Geophysical survey and modeling needs |
High-resolution, Rank 1 aeromagnetic and radiometric surveys. |
| Digital elevation data needs |
Lidar complete. |
