Diamond and Gold recovery on the Caroni River Venezuela

This is a picture of an 8 inch cutterhead suction dredge I spent a few days working on on the Caroni River in central Venezuela.

This dredge ran round the clock and they had a good recovery of fine gold and Diamonds. The large sluice box was effective at recovering the fine gold of the Caroni river system and they had a series of rougher jigs to capture the diamonds and they appeared to be very effective.

The layers of successive Iron cappa had free flowing gravel underneath and this robust dredge was pretty good at breaking through this to get at      the auriferous gravel. I was fortunate to get to spend the time with these local miners and it really helped me with my initial reconnaissance of the river.

I later spent 7 months operating and retrofitting an 8" airlift dredge and managing an extensive sampling program for a US based company.
