Im not a geologist, but the box stands, the ironstone and some of the cutouts on the GV hwy north of the Goulburn showing (deep) marine channel deposits always made me wonder.
Ive searched a few times on trove on the old and new names around there only to come up with no obvious results.
The Nagambie project and Violet town success leads me to think the ground might be the outer edges of the same geo timeframe of the Nagambie/whroo/rushworth, but is it gold bearing is the question.
Being right on the River I would suspect had anything noteworthy been recorded it could be searched.
Strange though you have King Parrot, Ghin Ghin and Yea, Nagambie, and those southern deposits but nothing obvious right there.
Ground looks good if not deep, but not anywhere I can point you to.
Good luck.
