MarAthena twin engine

4D geological twins

Site-accurate landforms, ore shells, and a seismic survey on every twin. Each shell is cross-walked to the line that would image it. Fourth axis is production year.

Morenci

copper

AZ · Porphyry Cu-Mo

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.

Bagdad

copper

AZ · Porphyry Cu-Mo

Precambrian-hosted Laramide porphyry with hypogene chalcopyrite and molybdenite.

1,100 on site · 520 m · 2 surveys

Bingham Canyon

copper

UT · Porphyry Cu-Au-Mo

Eocene Bingham stock. Classic zoned porphyry with Cu-Au core, Mo shell, Pb-Zn-Ag skarn and lead-zinc carbonate replacements. One of the deepest open pits on Earth.

Resolution

copper

AZ · Porphyry Cu

Deep, high-grade Laramide porphyry beneath the Apache Leap tuff. Block-cave candidate.

400 on site · 2100 m · 2 surveys

Cortez

gold

NV · Carlin-type Au

Carbonate-hosted disseminated gold along the Cortez Hills and Pipeline trends. Refractory and oxide ores.

Carlin Complex

gold

NV · Carlin-type Au

Type locality. Submicron gold in arsenian pyrite in silicified-decalcified Roberts Mountains / Popovich carbonates. Multiple pits and underground (Leeville, Pete Bajo).

2,800 on site · 780 m · 3 surveys

Rochester

silver

NV · Epithermal Ag-Au

Koipato rhyolite-hosted veins and disseminations. Heap leach. Largest U.S. primary silver mine.

Lucky Friday

silver

ID · Vein Ag-Pb-Zn

Coeur d'Alene district. Steeply dipping silver-lead-zinc veins in the Revett Formation. One of the deepest U.S. mines. High seismic risk — rockburst monitoring is core to the 4D twin.
