Techniques in mining
You could use mine shafts as a technique with the use of a windlass, pick, bucket, puddling, a mineshaft and a few friends.
You could use gold panning to find alluvial gold with the use of a gold pan.
If you were lucky you could use dredging to find gold using a dredge.
If you had enogh money you could do cradling which was placing sand/sediment into a cradle and shaking it.
Maybe you could use puddling to find gold by placing clay into a large container and then stir it with a paddle or some sort of stick.
