The Little Billie placer gold showing occurs at the confluence of the Chilcotin and Fraser rivers where a bar has developed at the mouth of the Chilcotin River. As a result of low water velocity the gravels being deposited are generally not of large size, although occasional floods appear to have deposited larger boulders. The gravels have been deposited on clay-rich sediments.

In 1945 gold to a value of "50 cents per yard" (about 46 cents per metre) was reported to be present near the margins of the bar.
