porphyry deposits lack significant volumes of phyllic or advanced argillic altered rock. Magnetite is an important vein and alteration mineral in the high-grade core of some gold-rich deposits, and can locally comprise up to 10 wt. % (e.g., Grasberg, Irian Jaya; Kavalieris et al., 1994). Unmineralized

How do iron ore deposits form? Quora
Contact ores Iron ore deposits formed at or near the contact between igneous rocks and sedimentary rocks are normally composed of magnetite and hematite with associated carbonates and pyrite. The ore deposits are usually in the sedimentary rocks as irregular or tabular replacement bodies.
The ore deposits are mostly large, solid slabs of iron ore, extending several hundreds of metres down into the ground. Mining ore at great depths is a logistical challenge that places demands for a well-functioning infrastructure, roads, facilities, communication
