DIRECT ANSWER
The Eureka Creek Dredge is a 75-year-old, 350-ton floating bucket-line dredge resurrected by Tony Beets. Moving, rebuilding, and operating this historic behemoth was a massive logistical risk, but its unparalleled ability to process gold at an incredibly low cost-per-yard made it a cornerstone of the Beets empire.
Tony Beets' decision to buy, dismantle, transport, and rebuild a 75-year-old floating bucket dredge at Eureka Creek is one of the most audacious engineering feats in modern gold mining. Most modern operations use excavators and diesel wash plants, but Tony understood the forgotten mathematics of the dredge.
The Ultimate Low-Cost Gold Catcher
A bucket-line dredge is essentially a floating factory. It digs its own pond, scoops up the bedrock with a continuous loop of massive steel buckets, washes the gravel onboard, catches the gold, and dumps the tailings out the back—all using a fraction of the diesel fuel required by a fleet of excavators and rock trucks.
The upfront capital cost to rebuild the dredge was staggering, running into the millions of dollars. But once operational, its cost-per-yard to run was astonishingly low. It allowed Tony to profitably mine ground that would have bankrupted a traditional excavator operation.
The Risk of Vintage Iron
The downside of running 75-year-old equipment is that you cannot just order replacement parts from a catalog. When a bucket pin shears or a trommel gear cracks, it requires custom fabrication and intense manual labor to fix. The dredge required a dedicated team of mechanics simply to keep it afloat and digging.
Historic Dredge Tailings
For the independent prospector, historic dredge tailings are a massive neon sign. The giant bucket dredges of the early 20th century were efficient, but they often missed fine gold or left behind rich pockets of bedrock that their buckets couldn't scrape clean. Modern small-scale equipment can often successfully rework these old tailing fields.

How does a bucket-line dredge work?
A bucket-line dredge floats in a self-created pond. A continuous loop of steel buckets digs into the pond floor, pulling gold-bearing gravel up into an onboard wash plant. The gold is captured in sluices, and the waste rock is deposited behind the dredge via a conveyor belt (stacker).
Why did Tony Beets use a 75-year-old dredge?
Because a dredge requires no rock trucks or excavators to feed it, its fuel consumption and operational cost per yard are extremely low. It allows a miner to profitably process low-grade ground that would cost too much to mine with modern diesel equipment.
Are there still bucket dredges operating?
Very few. Most commercial placer operations have shifted to excavators and stationary or mobile wash plants due to the high upfront capital cost and strict environmental regulations associated with floating dredges.
