    Yeah, there is gold in that area but only in a couple spots. The Yampa itself isn't known for gold at all. Next time you're headed that way, PM me for tips on where to look...

    Got out to my honey hole for an hour of digging today and managed to run my Sniper toooo steep. It can be done. Net result, I lost about 1/2 the gold into my tailings. How did I know? By both the small amount of material in my cleanout pan and the exclusively large size of the gold. What did I do? Easy, I just reset the sluice and reran my tailings. A quick and productive process.

    Here's a pic of that first cleanout with just larger gold:

    Too steep? How did that happen? Just not enough water running so you made it steeper? Inquiring minds want to know....

    Nice looking gold, though.

    Thanks Dave. What happened is I built a dam in a new spot several weeks ago then came back last weekend to use it for the first time. In between times the creek filled in behind the dam with sand so the top end of my sluice was higher than I intended and indeed TOO high. When I reset the sluice I had to raise the lower end to get back in the high gold retention range. A very, very rare problem

    Ok time for a rod mill update!
    You may recall that I built a tabletop rod mill, ran a couple test batches and then burned out the little motor on it with one of my experiments. I've yet to build a new one but here's why I will:Click image for larger version.

    Crushing in the mill did a great job of flattening the hidden gold... Cool right?

    Here's the mill rods (not all rods!) and tumbler. Notice the drywall screws used to maximize tumbling. Worked amazingly well using the chassis of an inkjet printer. Click image for larger version.

    PS the material was all ready processed magnetic super cons with NO visible gold. I removed everything that was still magnetic before panning the post-milling material. The gold and black sand you see is almost all +30 mesh.

    Wow, I have an old spike like that from the Denver, Rio Grand and Western RR. It looks like a bit of bicycle chain and some small iron rods. I can do that now!

    I love the flattened gold picture! That is exactly what it is supposed to do. Have to get started on my rod mill!! Thanks for the update.

    BTW, how long did you rotate the mill?

    Hmm, an hour or two I think. Not longer

    The rods are from the printer chassis paper handling mechanism. The chain came out of the creek and is a bit bigger than bicycle, it's rusted solid. The mix of iron and screws was to ensure I got tumbling instead of just rolling. The spike is from Big Bend!

    Looking forward to seeing your results Dave!!

    What is this rod mill business? Sound interesting, what's it all about?

    It's basically using a rock tumbler to crush your super cons after you get all the visible gold out. I'm too cheap to buy a rock tumbler so I made one out of an old inkjet printer and the canister pictured. As you can see it breaks up the material and flattens the gold particles hidden in the brittle sands.

    The gold and sand pictured were from one of several experiments I ran...this one was all magnetic material at the start. After processing, a surprising amount of non-mag material was liberated due to shattering the granules, and of course the gold

    Oops, don't know. I'm a failure, sorry. I would guess the too steep was like a 30 degree angle and backing off to 20 degrees did the job. Just guessing sorry.
