Maddingley Mine near Bacchus Marsh Railway Station, Victoria, Australia contains a concentration of a particular brown coal (lignite) formation called Leonardite. A relatively high altitude formation, Maddingley brown coal is distinguished as having 60 per cent moisture content and a rich fulvic acid and humic acid content. A declared strategic State mining reserve, the estimated 400 million tonne deposit at Maddingley is the largest of three known deposits of high value Leonardite in the world, the others occurring in Mexico and Germany. Maddingley is the site at which the Coldry Process densified coal technology was developed.
