Hi Charlie,

This was the reponse from Dredge manufacturer. As you can see a single dredge like our 50TPH could collect one ton over ten days. With all four running that could be every 2.5 days. Plus the 150TPH running as well would reduce it even further.

Hi b4,
This as you may imagine is nearly impossible to evaluate. I can tell you that on a typical day in our California Streams and rivers you should be able to amass approximately a couple hundred pounds per day of concentrates provided you clean up twice a day.

Subject: Concentrate recovery over length of run

Dear Sirs,

I am curious about how long it would take for a 50 ton per hour commercial alluvial dredge to acquire a single ton of concentrate.

I know the run rate and material may vary but am trying to evaluate the time frame for return on investment.

My assay in question came back at 170g/ton of concentrate.

Would something like your big 40 horsepower dredge collect a ton of concentrate in a day, a week, a month?

Thanks for your time,
