Re: Season Updates?

Re: Operational improvements for improving hand mining (highbanking) efficiency - Lean Manufacturing style

One thing that comes to mind is the idea of "circles" (a moving excavation / settling /tailing pit) Dig for a certain interval (lets say 2 or even just 1 day or so) and discharge your new tailings to the side of your new excavation. Then start moving the digging in a circular direction while using y...

Re: Spring hauling to new prospect

It sure is nice to see (and learn) from you "Big Boy Pants" guys about this. At my operation I have to haul my "stuff" sometimes as much as 20 yards from the Polaris six wheeler to "The Spot". All those round trips to hand carry the highbanker, Honda 2" pump, 2.5 gal portable fuel container, True Te...

Re: Properties of punch plate (or Jarvine Riffle) for improving gold capture

So ............ Which comes first - the chicken ( with "documented evidence and proof" beyond reproach) or the egg (something new that the inventor makes certain claims as to recovery improvements)? Ever use extruded or cast rubber mats? Who decided to try them, found them to be VERY good at recover...

Re: Soil samples for placer indication

"For what it's worth I have had a company that was prospecting in the area for hardrock deposits ask permission to do soils on my claims. While some of the samples came back an anomaly none threw up any big red flags." Dick, I have seen the same sort of thing happen at a friend's claim a few years ...

Re: Properties of punch plate (or Jarvine Riffle) for improving gold capture

Pickaxe,
One other aspect of the punch plate is that it shears off almost all the down stream force of the water/slurry and redirects only some of the flow downward to slowly wash the undersized material from around the denser Gold.

Re: Properties of punch plate (or Jarvine Riffle) for improving gold capture

Just as GWiz has many, many years of experience doing these old things using his rewarding, traditional, ways, many of us only see those old ways as just OLD, inefficiently developed things that came about from the random efforts of desperate and usually unskilled novices. Nowadays we evaluate those...

Re: Is drift mining a practical way to mine nowadays?

Here are two guys working in interior Alaska who are dropping a shaft this winter. Something those who are interested in drift mining might find interesting.

Re: Properties of punch plate (or Jarvine Riffle) for improving gold capture

Doc, over at Gold Hog, had a few tutorial videos addressing fine tuning a box with mats to maximize recovering many different Gold sizes all the way down to fly poop. Slowing and / or flattening the water and sluice, it turns out, isn't as critical as controlling by pitch the water speed over certai...
