Let's do some underwater blow mining in California this summer
There is a way to use the motors, pumps and hookah systems we normally use in our small-scale mining activities to excavate gold-bearing material on the bottom of California's waterways, and even direct the material through a sluice box floating on the surface, if you choose to do so. This new method of "blow mining" is outlined with video demonstrations in our March newsletter right here:

We hope you will join us this summer along the Klamath River in northern California!

Good write-up Dave.

I'm looking forward to getting over the hill. Do you know any thing about the snow pack on the road over Little Grayback?

Also Dave, I didn't see mention in the newsletter of vac-pack use along the river banks. Is this still OK?

Thanks Dave,
Mike

Hi Mike,

Feel free to use your Vac-Pack as much as you want. A Vac-Pack has always been considered a dry mining activity, and was not designed, intended or really capable of being used as a suction dredge to excavate materials from the bottom of an active waterway.

I was up in Happy Camp about three weeks ago, and I was told that Grayback was open. I'll be in contact with a couple of friends over the next couple of days, and get an update of the pass.

I recently received the March 1st Snow Survey Results from the Forest Service, and it appears dismal at best. One location at 5500 feet normally has 73.8 inches of snow in February, and on March 1st it had .8 inches of snow. In terms of water content, that location would normally have 25.8 inches of water, but this year it is .4 inches of water. Scott Mountain revealed that it had 10 inches of snow where the February average is 54.7 inches. That location averages 20.8 inches of water in February, but this year it measured 3.5 inches of water.

Based on that report, you just might be using your Vac-Pack in some new locations.

Hey Rich, good to hear from you. Thanks for the info on the vac pack. I thought it was still OK but there's a lot of chatter on the internet so I asked for all.

I kind of had the notion there wouldn't be much snow over Little Grayback. While we can certainly have a few snow storms this late, as well as later in the year, we really are past the prime pack snow months. Working daily along the Smith River over here on the coast, I see the rapid rise and fall of the river with recent rain storms. The river will run at medium high levels for a few days, then drop right back down to low level and clear as gin.

I think this summer is going to be one of the driest on record as far as river flows and ground water levels. Probably be a good year to be in the water well drilling business. I know I'll have neighbors who's well will dry up this summer and have to hook up to mine until substantial rains come again.

Thanks again Rich,
Mike

Watched your video on this method...I LIKE IT! I am going to work on a set up. Is the hopper home-made or can I find one somewhere?

We glued those hoppers together out of ABS plastic. I suppose there are a bunch of ways you could make them.

I've had good luck ordering plastic sheeting from these folks. The selection of thicknesses and colors are great. They supply adhesive and technical advise also.

My favorite is the 3/4" pvc marine decking material. It's expensive but real nice to fabricate with.

Re: Let's do some underwater blow mining in California this summer
I started making mine. Size the size of the hopper isn't relative to the material processed, I started with an old hopper from a drywall texture gun. Nice little size and should reduce the drag from the current.

Trying to figure a way for a plugger pole because we all know how Mr. Murphy loves miners

I checked with the Forest Service yesterday afternoon, and I was informed that Grayback is open to vehicular traffic. I talked to Montine this afternoon, and she confirmed that it is open to traffic.

Re: Let's do some underwater blow mining in California this summer
This is a great idea you guys came up with and will no doubt help miners find good gold this year.

You could also use a manual hand dredge, which are legal, to suck up material off the bottom of the river and put that through your highbanker floating on the surface.

Can't wait to get back to Happy Camp!

Re: Let's do some underwater blow mining in California this summer
Hey folks; could use some expert advice on the hopper system. I have a 2 1/2 highbanker/ dredge, would it be a waste of time building this kind of recovery setup on a smaller machine? Would appreciate your recommendations
:thankyou:

I use a long piece of number 6 ground wire for unplugging my 1 1/2 in. hose... it's lite weight and i coil it up for easy transporting . if it's long enough you could double it up to get more pushing power...

Re: Let's do some underwater blow mining in California this summer
what do you think would be the maximum distance you could "blow" material down the hose to the sluice, say for a 2 1/2 or 3 in hose before it slows down too much and starts to plug up?

I have a nice piece of EMT for a plugger pole for my dredge but my concern is a blockage at the hopper end

Re: Let's do some underwater blow mining in California this summer
OK...so we've got a plan here that involves no suction or suction nozzle to get the gold off the bottom. This fact alone seems to negate any legal assumption that one is suction dredging no matter what other equipment is around him.

The prohibition for any suction dredge to be within 100 yds of a closed river is also negated by the fact, it is not a suction dredge if there is no suction being used to extract the minerals.

To quote DFG's Emergency Regulation definition of Suction Dredging:
"Under the existing and proposed definition, the use of any vacuum or suction dredge equipment (i.e., suction dredging) is defined as the use of a suction system to vacuum material from a river, stream or lake for the extraction of minerals."

Ergo, I want to put some kind of sluice or other recovery system, maybe underwater, to run my pressurized slurry through, within close proximity to my hole.

I believe this would be legal, in as much as Iam not suction dredging, nor do I have a suction dredge within 100 yds of the river, because I do not have a suction nozzle within 100 yds of my equipment.

Could they cite me, or take my equipment?

What say you? :doublethumbsup:

Re: Let's do some underwater blow mining in California this summer
Mojave you're pretty much asking for opinion. I don't know if anybody has been cited yet. I think any reasonable attempt on your part to fit in to the current mix, would be the safest method.

On the other hand, unless we explore the boundaries, we'll never be comfortable.

As hard as the New 49ers try, I am confident that we understand CDFG intentions as well as can be. There's a slew of unknowns and confusion. I trust Dave and Rich to keep us posted on everything concerning regulations and how to avoid trouble.

Re: Let's do some underwater blow mining in California this summer
Well, the way I see it, I will be operating within the boundaries of the current regulation, which is very specific about what "suction dredging" is defined as.(above)

Having been in CA law enforcement myself for a couple decades I know one thing for sure. If you make any law or rule too specific, there will always be a way around it. We have already proven that to be true with this new blow mining method. Might even consider that DFG's 'specific' rule making did us a favor in that way.

If I get the chance this year, I think there are many new methods to be tried, that will be outside the strict definition of "suction dredging".

I am not worried too much about some officer trying to cite me on first contact, especially after I explain why what Iam doing is 'Legal'. Ive been in those enforcement shoes, and making an improper cite that cannot be supported by quoted text from the regulations is a big problem for any officer. One they'd rather avoid. So I doubt we will be bothered much unless one appears to be using a "suction nozzle" underwater. In which case, he will have to show that he 'is not'.

Should be an interesting mining season this year.
Hope to meet some of the members out on the Klamath this spring, as it will be my first trip to the claims since I joined 2 years ago.

Yellow riffles to everyone! :doublethumbsup:
