|Mount Griggs||2317||1790 BC ± 40 years|
|Hayes Volcano||3034||1200 ± 300 years|
How is cinder cone volcano formed?
Cinder cones form from ash and magma cinders–partly-burned, solid pieces of magma, that fall to the ground following a volcanic eruption. This type of eruption contains little lava, as the magma hardens and breaks into pieces during the explosion.
Why do cinder cone volcanoes erupt?
Cinder cones are the simplest type of volcano. Explosive eruptions caused by gas rapidly expanding and escaping from molten lava formed cinders that fell back around the vent, building up the cone to a height of 1,200 feet. The last explosive eruption left a funnel-shaped crater at the top of the cone.

What’s the history of the Mt Gordon Mine?
It has a history of intermittent copper production, attempts at novel treatment processes and periods of closure dating back to the 1920s. Recent developments in geology, exploration and production, which have transformed the economics of the deposit, are the subject of this presentation.
What kind of geology is found at Mt Gordon?
Richardson and Moy (1998) recently updated the geology and mineralisation of the Mt Gordon Copper deposits. The pyrite/chalcocite/chalcopyrite ore bodies at Mammoth, Esperanza and Esperanza South, are localised in brittle breccia and replacement zones associated with a series of interconnected faults.
