Apart from the creek and some its small tributaries may also be worth while panning off some of the dirt from the old times holes in the area.
There are a few dams/waterholes in the area, grab a bucket or so of dirt and pan off at the dam.
Slaty Creek seems to always give up a little no matter how many times its been dug over.
Good luck, T.
Oh and you should do OK hiring a detector .... think SDC, switch on and go, dynamite on small gold (but finds the bigger stuff as well.
