about the process, "elutriation"

The Process

Elutriation is a physical process that is used to power the ability of the GOLDROP to separate Gold from pay dirt.

Get more than just Gold!

Because the Elutriation process is a density separator, all "heavier than dirt" dense matter falls into the jar.

Get Platinum, Palladium, Silver and all precious metals

These precious metals are much more dense than dirt and will readily fall out of pay dirt into the jar if present. Even heavy metals you don't want but will help eliminate from the environment such as Mercury, Lead, Copper, Iron Pyrite, Meteorite or any dense metal or mineral will fall into the jar, maybe even gem stones.

watch the chaos that goes on in the goldrop trap

Here you can watch the turmoil and chaos that goes on inside the GOLDROP trap. The continuous waterfall from the feed tube funnel and the rising water flow from the elutriation tube provides a turbulent tossing of the pay dirt in the trap and circulates from top of the GOLDROP to the bottom. This action keeps the Gold falling out of the pay dirt and into the jar. Notice the smaller, less dense matter resides at the top of the trap before exiting and draining into the tailings bucket.

results from the black sands of Cape Disappointment

In this video you will see the results of mining the black sands of Cape Disappointment, Washington on June 22, 2019 using 2 GOLDROPS to separate the Gold from the sand. Not only did we find Gold but also Mercury, Copper and Iron Pyrite were separated out and recovered from the sand.  Look close there's silvery matter , possibly Platinum  too! The GOLDROP does not discriminate. If it's heavier than dirt, it ends up in the jar.

About Us

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.

In this GOLDROP demonstration watch how much Gold is in this sandbox play sand. Watch too how the GOLDROP separates "lead" from the dirt which weighs "much less" than Gold! 

Sluice Goose goldrop eats crow

This video demonstrates the results of processing 1 yard of Clay pay dirt tailings processed through the GOLDROP. The wire Gold claimed in the previous processing video is NOT WIRE GOLD. It turns out to be gold colored BRASS! A different kind of FOOLS GOLD! Watch John eat crow in admitting to this result. No Big Deal! It only demonstrates the uniqueness of the ability of the GOLDROP to separate a variety of materials of varying density!

Sluice Goose latest GOLDROP prototype REVEALED!

Watch how the latest GOLDROP version separates small Gold from previously panned black sand from Cape Disappointment, Washington State. It's new, compact, light weight  and transportable. It weighs less than 40 lbs. and comes in its own drum. 

the goldrop vs. mercury in black sand

Watch how the GOLDROP separates Mercury from black sand. In this  video you will witness the removal of Mercury, a poisonous and deadly liquid metal. The GOLDROP is an  invention that can help to remove Mercury from contaminated sights.
