If there are rich deposits....patches, pockets, lodes in reef etc they will be shedding and have done so for many years.
Now how much depends upon the friable nature of the deposit of course....softer gold bearing horneblend like Schist or the likes, will shed more than a hard quartz reef will.
The steeper the rise to the brow, the more narrow and concentrated the downhill run of course gold will likely be.
Check the steep slopes where the ground cover is shallower because of constant rain and wind moving the soils, and likely the course gold with it.
Look for places that trap the shed on the way down ie flats halfway down before the deeper gullies, large rock croppings along the slopes, thick vegatation etc.
Look for evidence of 'slides' on steeper slopes. Evidence of what is known as a 'slide' is a mark or floor resulting from friction caused by a moving mass on a lower surface area. Something is nearly always visible to show it and concentrate any efforts there.
Look for areas of pressure, red bars that are boat shaped etc that run across the hill.
A lot of people generalize an area no matter where it may be.....only the keen eye who reads the ground and vegetation within rather than a map, will prosper most.
Just my opinion
