Most PI detectors have a depth of less than 30 inches. I am wanting a larger 5-15 feet depth capability. Current detectors are good at finding surface pay streaks of modern flood gold. The deposits I am after are the ancient deposits which will be larger pieces and much more concentrated. Try to...

The airborne electromagnetic mapping information was good and shows the possibilities of larger PI arrays. Thanks for sharing this. The gold I seek is normally found within 15 feet of the surface. As you said no point in "detecting gold that you cannot reach". Which is why I set a goal of 15...

You brought up deep lode gold deposits. Indiana geology has no lode gold. Our gold is all placer gold on the surface of bedrock. I am not trying to start a lode mine down to 8000 feet but rather make surface operations more economical and profitable. Silver has gone from $4.30 an ounce in 2002...

You are correct to some degree. It is not a "solid" layer, but it is concentrated greatly on the bedrock. Particularly here in Southern Indiana as we have had 3 major glacial events that bulldozed the till from Canada flattening much of the Northern part of the state and depositing that material...

This is progress. I agree a larger array or coil will be required. Perhaps a device that is trailer mounted would be more practical or something that say 4 men could position and allow to remain stationary for the required length of time for the depth of the site (some areas I am looking at have...

My Grandfather Charles Wayne Bensheimer was an Army engineer for over 38 years. He won many Gold plated sets of Craftsman tools for his designs. Many told him it would be impossible to create an off-road firefighting vehicle with a large water tank capacity and that a 4x4 truck was the best...

With all due respect metal detectors have advanced by leaps and bounds since 1975 with every few years some amazing breakthroughs have happened. We agree the assumptions must be changed. That is why I joined this forum. Fresh ideas from young minds open to new ideas, untested methods, and...

Dave, No worries or need to apologize. I deal with gold miners regularly and some have a pretty twisted sense of humor. I have thick skin and can take it. I have some knowledge of variable pulse induction and its applications for finding shallow or near surface gold. I will agree...

Engineer's have changed the world many times. The greatest thing about them is when people say "That is impossible" they take it as a challenge not a fact. The joke was funny and I apreciate a good sense of humor. Is your intellect as sharp as your wit? Let's solve this! And thanks for the laugh!

Already done prior to this post being made. Posted in Other Physics Topics. Thank you for your reply. https://www.physicsforums.com/threads/what-wavelength-can-penetrate-soil-to-15-feet.1013871/#post-6617495

If you worked with me creating and testing said device and patents were applied for and granted I believe a 50/50 partnership would be fair. I would do the field work testing it and taking it to mine sites (for a commission of the gold found also to be split 50/50) leaving you to the lab work to...

I agree with you. Gold is used in most electronics and has industrial uses, plus it is valued for it beauty and worn as jewelry. If the price suddenly dropped many more would buy it both as an investment and for it's properties. Supply and demand means it will never be "worthless".

I have been a gold dredger over 30 years. I have done pretty well for myself using conventional means such as a 5 inch gold dredge and a variable pulse induction metal detector. This isn't simply a case of "gold fever"... I make a nice living from it (in a state where that is rather hard to do...

Hello everyone. I have been a gold prospector for many years. I am looking for some insight into the physics and wavelengths used for ground penetrating scanning and discrimination. Specifically to a depth of 10-20 feet. I would like some out of the box thinking on this we all are likely aware...

As my name suggests I am a gold prospector. My question is what wavelength would penetrate 15 feet of soil, sand, and clay but be stopped when it struck gold? The goal is to create a device that will allow for looking into the ground in such a fashion as to be able to create a visible display...
