In Regard To Non-metallic Minerals

[Nightryder]

Hello everyone,

I'm starting this topic to seek help to find a way for locating non-metallic minerals like diamonds, gemstones, coals, antiquities.. etc. And to teach me a little bit about 3D imaging devices, or what's so called long range locators. I need to know whether they are practical or not. And maybe some other machines that I do not know they exist. I understand some of which can be very expensive, but here is my story:

I recently signed a contract with my government for exploring and potentially mining resources under the ground which can be metallic or non-metallic. Soon I will be provided from their side with more topographic and geological maps, and satellites images of where and what to expect to find. I was already given a long list of minerals that are worth digging up including 40% or more of crude iron. Frankly speaking some of the metals or rocks in that list, I have never heard of but I think with different types of metal detectors I can find anything that is metallic.

As they sent me the first batch of those maps, and with the help of my brother, we went on a 5 days exploration trip and we scored a large commercial quantity of bauxite, which is basically another word for aluminum. And boy was it fun and promising?!! We were planning to stay longer but we had to get back to civilization and file for our first discovery and send them a sample of it.

Bottom line is that I guess I will be okay dealing with all types of metals, including those I never heard of; However, I'm definitely appreciative for any ideas or experiences about ways to search for the non-metallic stuff.


Thanks!

That is a question for professional geology. No metal detector will help here. LRL is quackery and a complete waste of time.
Of course; the market is flooded with all kinds of heavy nonsense and scams that make various SciFi claims in their advertisements.
Forget all that! Consult a professional geologist for the best opinion and advice.
Aluminum in the form of bauxite ore is undetectable with hobby detectors like the ones we're dealing with here.
I don't believe that magnetometry can help here either.
Because magnetometry works only and exclusively on the principle of measuring magnetic anomalies on the earth's surface.
I've been having a lot of fun with the History 2 (H2) channel lately!
I enjoy watching and laughing at some shows.
There was almost a show in sequels about the search for the famous Yamash"ee"ta treasure. Ha, ha, ha!
At one point, they hired a GPR "expert" to "scan" a certain area with a "baby carriage" (GPR) and try to find a "cavity" (channel, corridor, cave, whatever).
A young (creepy-looking) "expert" came, "scanned" the surface and came to the conclusion that there are indications of a cavity at a depth of 12 meters.
They brought expensive machines, drilled, broke a couple of expensive drill bits, spent a lot of money.
It was clear that it was quackery and that GPR was being used for wrong purposes!
GPR radars are primarily intended for construction works, that is, preparations for the construction of large buildings.
Later in the construction process; GPR is used by independent inspection companies to check the quality of reinforcement in concrete.
Today it is easy to make money from ignorance.
It is enough that you have initial capital, some kind of university degree (bought in Mexico, for example), to buy such a GPR and then charge a very high price for your "scanning" by demands of insufficiently informed naive people.
Therefore, even GPR technology, in the hands of charlatans, will not help.
Your problem can be solved by a really serious geological company, first of all an institute, with serious months-long and multiple measurements in the field.
With the use of several different technologies and not just one.
Each of the professional technologies will require a special team of highly specialized experts who have been in the business for a long time.
Everything else... FORGET IT!
Yes, that's right, reality is harsh and unforgiving.

The higher the price of an "almighty" LRL device - the greater the trust among uninformed people.
This video is hilarious but shows a sad reality:

Any methd to find gemstone bearing layer.river and old river channel are deposit area

[ivconic]

Not that I know.
Maybe someone else knows.

Can use gradiometer meter find old river channel ?

[ivconic]

I think you can.
Take your time and read this book very carefully:

You can use ground balance, for different soils GB is different.

Hi Ivconic,

Thanks for your informative reply

I have always had my doubts about LRLs, but as I'm starting in this business, I have to learn about what's good in the market and about what's not good too.

The detectability of a Bauxite rock, for example, by an average detector is dependant on more than the usual factors such as: depth and size of the object. Since Aluminium can no be found pure in nature, you need to consider its concentration in the rock or soil. In other words, if the detector does not go off over the rock, then it is probably not worth digging or collecting due to Aluminium production cost vs. its prophit. In fact, you may as well go easy on the sensitivity of that detector to build your own experience in determining the least concentration percentage you are looking for. Most if not all Aluminium production factories around here require at least 40% concentration.


I do not think hiring a professional can help much. Simply because I can acquire all types of maps and satellites images of the area I'm going for. So I, in general, have an idea of what to expect, however working in a vast areas makes you think of how to save time and sweat as much as possible. So, what I'm hoping for here is to find out where exactly I should dig, let's say for an ancient city or an emerald formed inside a rock. Think of a "pinpointer", perhaps a big one, for non-metallic stuff which they can stand out on its screen.

Hi Pito,

For crude not pure metals yes, but then you have to take a sample and airtest it.
