Each shell is tied to the survey that would image it. Desk compilation from published USGS / industry methods — not the operator’s confidential cube. Not a reserve.
| Ore shell | Survey | Method | Year | Tie | Vp m/s |
|---|---|---|---|---|---|
| Hypogene Cu-Mo core | Line M-04 (N-S) | 2D reflection | 2016 | Ties the shell | 2200–6100 |
| Molybdenite shell | Line M-04 (N-S) | 2D reflection | 2016 | Ties the shell | 2200–6100 |
| Chalcocite blanket | Line M-11 (E-W) | 2D reflection | 2018 | Ties the shell | 2100–5900 |
| Hypogene Cu-Mo core | CSAMT traverse A | CSAMT / AMT | 2012 | Structural offset | 1800–5200 |

PhD geological read
User-initiated. Grounded in MCS 2026, the mapped ore shells, and the seismic crosswalk. Not a reserve.
Laramide porphyry copper. Potassic core with chalcopyrite-bornite stockwork, phyllic halo, leach cap and chalcocite enrichment blanket. Gravel/Gila conglomerate overburden on the southeast benches.
