What's this rock

[Ward69]

Getting at lot of these lately. I've broken down some. Small flood gold.

Conglomerate

Either decomposing or forming. That is my guess

How is it formed. Mostly light gravel with sticky white clay. Around it. Got a few nuggetlets. And lots of fines. Following Malo

A quartz pebble conglomerate, probably an old one that is breaking down rather than a new one forming. The vein quartz that forms the pebbles gives a clue that it might contain gold (as you say it does). Not sure where your clay is - between the pebbles? Often with old gravels the clay is actually rock pebbles (eg siltstone and shale) that has weathered more recently to clay. Original clay plus pebbles is far less common.

Gold out there is known to be in clay. That is why they used a puddler sometimes. What you have looks like the same stuff just dried up.
It should crumble pretty easily.
