In typical fashion i've just found the maps. One map shows the location of the leases and the locations of two shafts, named Brights shaft and Ringwood shaft. Assuming their locations are accurate, google maps places them at around 27 Mt Dandenong Rd between Braeside Ave and Mines Rd. Both shafts were close together and connected underground.
The other map I found labeled 'Ringwood Gold & Antimony Mine, Ringwood' shows the traverse and longitudinal sections of the mine. It had 4 levels at 184, 244, 304 and 372 feet. Winzes connect levels 2 & 3, and 3 & 4. The map also shows some surface workings and several other small shafts. This map is dated 20/12/1921.
Hope this helps someone!
EDIT: Just found a 3rd map showing more shaft locations.
Directly north to the previously mentioned shafts, Brights and Ringwood, was the location of the 'Ringwood Gold & Antimony Mine' (originally called Boardmans mine). It was located pretty much where the Maroondah City Council building is now, as was mentioned in an above article posted by Casper. 'Currans' shaft was located across Maroondah Hwy roughly where Leonard St is. A further two shafts were located to the East of these ones between Angus Ave and Velma Grove slightly east of the intersection of Valda Ave. I'm yet to find any information about these but have also just come across an article detailing the mining history of the area which i will look at when time permits.
