Some snippets from TROVE newspapers. 

Birth of daughter at El Dorado, April 1857

(Presumably this is Harriett, whose birth (according to the index) was registered 1858 at Beechworth.  El Dorado is about 25k from the town of Beechworth itself.  One always needs to be careful of birthplaces as the place of registration is not necessarily the place of birth.)

As these use only his Christaian name and surname they may or may not be your Richard BUTLER, November 1857.

If this is him then he seems to have done as some others - found that money was to be made by providing services rather than mining.
