125th Anniversary of Greta Coal Seam DiscoveryPrint Page

The plaque commemorates the 125th anniversary of the discovery of the Greta Coal Seam by Professor T. W. Edgeworth David in 1886. 

In April 1886, Edgeworth David began surveying the Hunter Valley coalfields and in August discovered the Great coal seam which yielded over £50,000,000 worth of coal up to 1949. Much of his time during the next four years was spent near Maitland where he was still tracing and mapping the coal measures and reporting to the government on other matters of commercial value.
