Bryan,
Cyanide treatment works best when the ore is crushed; cyanide does not
recover native gold.
You are correct that the richest tailings have been reprocessed, many
more than once. I've even lost a collecting location in Michigan from
reprocessing - it is all gone.
If you find tailing piles of rock, they have probably not been
reprocessed. There are still a lot of gold ore piles left, and they are
being looked at again by mining companies.
BTW, My oldest daughter lives in Denver and recently visited an old
gold mine in the area. She sent me four specimens from the tailings as
a gift (I'm easy, give me rocks and minerals anytime, but tell me where
they came from), selected because they all looked different. One of
them showed a bunch of 1-2 mm nuggets of native gold on the matrix
surface. I'm still trying to identify all the odd minerals.
Gold is where you find it, and it is still out there.
