stone with yamashita treas signs

Ram,
 I dont blame you of anything as i also know those bunch of yam-fakers flourishing in the philippines.. perhaps you are not the only one who saw and touched real yam-goldbar he-he! in ming forum? i only participated last 2007 and stopped on 2008,,,i was just screwed with many scams there but really some had touched real au there cause of my advice,,,

goldigger,

thanks for the insight on gold panning. im from the cagayan de oro city, mindanao, philippines whose english translation means 'river of gold'. what's the advantage of sluice against panning?

hope you could talk more about your experienced. thanks a lot.

Sluices and Advantages:

Can be small or can be big enough to load with a bulldozer (I will upload a photo of both);
Can process massive amounts of gravel;
Can produce lots of gold.

Sluices and Disadvantages:

Big sluice needs big machines and many men, so big cost (small = 1 person, 1 shovel, screen, sluice box and water pump.... very LOW cost);
Big takes LOTS of water and dumps lots of mud and fine sand, into streams;
Sluices are not efficient;
Sluices take experience, to work right.

Even a small sluice box takes a good pump, able to pump 1500 or 2000 gallons per hour. That is 6800 to 9000 liters, per hour. I do not know if you use liters, but a Canadian gallon is 4.545454 liters and a US gallon is 3.79 liters.... of course, my gallons are 4.545  L.

There is probably more, but its too hot to think, right now! Its 27 C, inside, while that is not hot by PI standards..... its hot for here, and very humid. We may have a storm tonight.

There are other ways for one or two people to efficiently recover gold, faster than panning. A rocker is one way.... try Wikipedia, it seems to me I saw a drawing of one, there. Although a rocker has problems, too, the problems can be fixed. Like, traditionally, some one has to rock the rocker, ALL the time: well, you can use a small 12 volt motor and gear box. It should be slightly adjustable for speed and travel (how far it goes, back and forth.) A windshield wiper motor may be strong enough for a small rocker.

A rocker should have a 2 second speed cycle, 1 second over and 1 second back. Plus a manual quick cycle or a motor double cycle speed. It  only needs a trickle of water. Traditionally, the water was poured in with a big dipper tool. like an 8 liter bucket on a handle. Also, you need to control how far it goes, each way.

A small electric pump that can pump 300 to 600 gallons per hour, is good... it saves labour and frees hands. You need a small dirt box and screen. That is a trough, that you scoop the gravel into, while it has a low flow of water through it. The water and gravel goes over a screen, the rocks slide off the side and the fine stuff, with water, goes into the rocker. You can have another screen on top the rocker, also. and a bit more water.

Rockers are as efficient as pans.

The rocker has a few simple riffles and rug, under the riffles (rug with 1 cm knap at the longest.) The problem with rockers is the sand tends to cake at the end of the riffles, next to the rocker sides, when this happens, gold will not be caught. It can be fixed by tiny jets of water, from a 5 cm tube, down each side, of the riffle frame. the tube must have at least a 1mm or 2mm hole, at each spot, so the water squirts into the sand.... this keeps it loose so the gold can sink to the bottom and stay there. the tube looks like:

water in here
  v
  I
  I
  I
  I-----0------0------0------0------0------0------0------0-----+ pinch or plug

The I is tube and ---- is tube and 0 is a tiny hole on the upper side of the riffle. You can connect the  two tubes up with plastic tubing and run them back to a valve.

When you take the riffles and rug out, it has to be done over a tub of water.... rinse all the sand off the riffles, into the tub and turn the rug upside down and scrub with the hand to get as much fine stuff out of the rug knap, as possible. Finally, rinse the inside of the rocker, into the tub, and then pan down the stuff in the tub. Eureka!

You can clean up everyday, do not let the rocker dry, over night, clean it while it is still wet. You do not have to clean up this concentrate, everyday, once a week is good, Sunday?

It would be better if I was right there, I could teach how to do this, better, than trying to explain. I have been panning since 1956, using sluice boxes since 1967 and rockers.

Lately I have some spiral pans.... they are supposed to clean right down to raw gold... they do NOT do this, but, they will concentrate, as good as a gold pan and much faster... just tip the pan back until all the concentrates go through the pan center, into a plastic pail, which can be 8 or 10 liter or a 20 liter. Small pails work better. It has to be fed with a trowel sized shovel, through a 5 mm or 6 mm screen... it is OK if you do not have nuggets, like me... all flour gold.

One of the spiral pans is call Desert Fox and it all fits into a snap top case... it has its own pump. I have another, I made, that is, I bought the wheel/pan part and made the rest, and I feed it from a tap in the household water. It works a bit better  than the commercial one...
I will see if I can get a photo of the Des.Fox. set up and ready to work.

For me, the commercial machine is small, light to pack and I can concentrate with it, it just needs to have a 12 v battery. I also have 3 solar panels, that fold up like a suitcase, for charging batteries. BUT! you can use a little 2 cycle generator.... I have 2 of those, also. You have to mix gas and oil like a scooter, motor bike or powersaw. One of them, both air cooled,
puts out 12v DC and 120 volts AC, the other, just 120 VAC only, so I use a clip on auto battery charger, with it.

Later, in August, I will be going to my claim and I will  take a bunch of pictures! Fortunately, I do not have to resort to a metal locator, to find the gold, on my claim... I found it in 1981, but did not stake it... some bunch of idiots did stake it, and all the country around. I have been waiting for them to lose interest, until a year ago.... they never did find any gold. The area became available and with our new system of staking, I did not have to leave home and did it on line!

Staking online means you have to have a FREE MINER-s license, and be in the system. I pay my fees at the local government agents office. I have a password and user name to get online.

I also have some hard rock claims, in the same area, for soapstone and obsidian, for gem use. The soapstone is like jade but softer, and darker... good for carving. I have not seen the obsidian, I was told about it by another miner AFTER I staked. I am hoping the obsidian has white spots, it is called SNOWFLAKE obsidian. I will see if I can find it, when I go, in August.

Well, ram, treasure finding is good, if you can find it, but one needs a practical thing to rely on, when the treasure does not want to be found. Which happens most of the time, for me.

Enough for now!  I have not mention suction dredges, I will save that for another time.

explorer125;

The only way I can see resistivity finding gold, is a massive amount of solid gold , or gold particles, would lower resistivity. It would take experience to interpret the results.

Any metal would lower resistivity, so the survey can only indicate there is something conductive, so if a dig finds gold, everybody hears about it, but if it was a pile of buried gas barrels, no one ever hears about it , because it was a success, in surveying, but a failure in finding gold.

By its self, resistivity is not enough, it is useful in ore vein location, where leaching, of chemicals from the vein, will lower soil resistance.

It may be useful to a dowser.

Does this help you?
