Btw it is an alluvial setting ( see the well rounded basal conglomerates) and the same paleo-deltaic alluvial fan setting exists in many places including Beatons Creek and ... the real Wits.
Tides probably did not play such a major role in rounding the boulders or pebbles. They did their job in sorting and re-distributing the gold in a Nome, Alaska setting as already described by Novo. Multiple level marine terraces cut in bedrock (laterally and maybe downdip from CW) could exist (each with its own load of gold).
Then parallel to the shore currents carried some of the gold away on adjacent beaches. Scroll down and read this page to understand currents https://www.miseagrant.umich.edu/dc/types-currents/ Multiple scenarios possible.
Complex interaction but this is not the point. The point is that you have to understand the real potential of the claims (mineral ressource estimates, grade, tonnage, location of the bulk samples) and how is that going to affect a future mining operation (economics).
Beaton's Creek is not CW/Purdy's. Different time, different land scape, different part of the ole Ur.
Does this look like what we have at CW?...
