GOLDROP recovers GOLD!

On September 12, 2018 the GOLDROP processed 50 lbs. of pay dirt tailings to get the GOLD. This dirt, provided by Dave Varabioff at, was previously processed on a shaker table by an Idaho Gold mining company.


A shaker table is the most efficiently effective device to recover Gold to date. This is a picture of Gold the shaker table missed! That makes the GOLDROP the most effective way to recover GOLD.


The particle at the top of Roosevelt's head is a mineral grain with GOLD stuck to it. What you don't see is the flour GOLD that is too small to photograph. The GOLDROP will be on the market next year.

More proof how efficient the GOLDROP is. Tiny pyrite dust means GOLD DUST TOO!  LOOK CLOSE!
