Gold Hog - A.R.M.P.

Back to Main Study


What the HECK is A.R.M.P. ? 

I want you to picture in your mind a working “gold spiral wheel”. (If you own one, or have seen one work, you’ll understand completely. If not, go to YouTube and watch one working.)
Look at the images below and tell me which is the right set up.

Tell me why?
Again, we go back to our earlier “knowns”.
Gold is the heaviest material in your box / material. 
So, while working the spiral wheel, most people want to see just a few grains of “black sand” actually falling into the center whole. Why? If black sand is lighter than gold but heavier than other materials, and a “few” particles are falling in, then through “rules of nature / science / physics” anything HEAVIER than those few particles should easily make it up there as well and be “captured”. Make sense?
Another way to think about this is to assign NUMBERS to materials.  The lightest being #1 the heaviest being #20.  If gold is number 20, and you are capturing some of number 19, then you could make the assumption that number 20 is also being caught.  However if your riffles are packing with all 20 weights 1-20, or even 10 of them, there might not be room for this classifying process ARMP to work.  

The same applies to matting.
"Passive mats" capture and hold most levels of the numbers. (1-20) Active mats, such as the Gold Hog UR and Wild Boar, work material down quickly only holding the heaviest of materials.

This starts the thinking process of a subject we call ARMP.  Active Reduction and Minimization Process.

Remember this rule of thumb…
You are NOT prospecting for “material”. So, having you riffles, matting, and box, hold a bunch of “materials” is not helping.  In fact it often hurts.  Next, you’re NOT prospecting for “black sand”.  This is the point that scares the heck out of many prospectors.  If your riffles, matting, and box are filled with black sand, and if that black sand is not being “actively worked”, then you are hurting your gold collection abilities.  However, if all the black sand is blowing out and none is being retained that is bad as well.
So….this again is very subjective to the area you are working. 
If the area has little black sand then you would watch your box and tune it differently. Working an area with a TON of black sand? Then you know what we mean.  In those areas it’s common to have black sand pouring out of your box onto the ground.  It is MATERIAL, not gold. However, if you’re in an area that doesn’t have much, and you see it coming out of your box, it’s probably time to clean your box or retune it.

In general…. A.R.M.P.  (Active Reduction and Minimization Process) is the process of working a large amount of various materials down to a common singular known, group of knowns, or similar knowns based on one or more .  If we know that gold (which is rare and often hard to see) is the heaviest material of say 30 combined materials running through your box, then “visually capturing” just the next lightest VISUAL material, or second heaviest, should allow us to feel confident that we are catching “most” of the heaviest (gold).  
This “unknown / undefined / unexplained ” rule of thumb has been seen or  used for hundreds of years, but we have never really seen it included or explained in “plain English” well by studies.  So, if “black sand” is the 2nd heaviest (and visual material) and you are capturing most of it, in “theory”, you should be catching most of gold. 
Most of the time this theory holds true, but it should only used as a “rule of thumb”. One also needs to make sure that SIZE of these materials is a common factor as well.  In other words…  if you only have medium and large “black sand” then this may indicate that SMALL black sand is escaping.  If the small “visual known” is escaping, what else might also be escaping? Yes, the smaller, similar known, fine gold.
