Ore genesis with igneous rocks. The world's major copper deposits are formed within the granitic porphyry copper style. Copper is enriched by processes during crystallisation of the granite and forms as chalcopyrite — a sulfide mineral, which is carried up with the granite. Sometimes granites erupt to surface as volcanoes, and copper mineralisation forms during this phase when the granite and volcanic rocks cool via hydrothermal circulation. Sedimentary copper forms within ocean basins in sedimentary rocks. Generally this forms by brine from deeply buried sediments discharging into the deep sea, and precipitating copper and often lead and zinc sulfides directly onto the
Ore railway station station has been unstaffed since a booking office fire in the late 1980s, and it has no other facilities. There is limited road access via Ore Valley Road (off Hughenden Road), but this station is not recommended for people with physical disabilities. The area has in the past been a hotspot for vandalism but is now covered comprehensively by CCTV. It is scheduled for a major re-development. There has been some debate as to whether the station should be renamed Hastings East or Ore Valley. Trains terminating and restarting at this station run forward into a turnaround siding which runs
