Hi Mike,
Thanks for the info.
Here is the page out of Leichhardt's journal -

Arcturus Downs was a property, acquired in 2002 by Aquila Resources, for
its coal. The coal deposit has been named Orion.

The name of the property goes back to at least the early 1900's.
A word of warning Scott.

Many of the square black dots you see on
Australian maps in more sparsely poulated regions are simply farm houses,
or "stations" as they are called. So if you are ever driving in those parts and looking
for food or fuel, don't mistake them for towns.
Best regards
Gary
