Gold detection at great depth

[Skull]

I recently inherited a few gold claims in Guyana South America. These claims produces gold grain ( dust) and nuggets, which is usually found between black sand and clay. The terrain in very rugged and have 2 rainy season per year, not to mention the depth they have found gold has been up to 50ft.
There is so much machines out there ( metal detectors, GPR, Magnetometers and Soil conductivity sensors. Can any one shed some light on this . Any feed back will be helpful.

Hi,
think that also moskitos..could be a problem there...anyway...about your question:
- wet soil is generally speaking a problem
- depth is another big problem (50ft--> more than 10meters...) means out of range for almost all portable devices...but magnetometers...that are unuseful in "natural" gold search.
Think that only solution could be gamma-ray camera...but I think you need something to drill wells too to reach about the depth required. Problem is that they are not civilian applications, disc is not present and are really dangerous stuff too.
Can't see good and easy solution for that soil/depth.
But maybe I'm wrong on that. Maybe ER meters can give you enough informations if connected to a datalogger computer...??? (don't know for sure)

Best regards,
Max

Why don`t you just do what you or the owners have been doing????
As you said, "....these claims produce gold grain ( dust) and nuggets...",
if that were true you`ld think you could sell your claim to a mining company and get royalties....saves you digging.

Hi,
yes I think he could do...and could be a good idea start a mining there. The problem I think is that maybe he just want (for now?) searching for big masses...big nuggets etc...instead of starting a mine. Also I know that authorities there have their problems with illegal gold mining...e.g. due to environment contamination (think at mercury release in rivers, cut of forests etc) and so think could be a problem obtaining rights and permissions also to start a legal mining activity by himself or by third party (so getting royalties).
I don't know...

From a TH point of view...starting a mine is not what one could expect ...nor the dream of any TH...and this is a good issue. Anyway, the question is good...
- what to use in warm, humid, bad soil at greater depth ?
Would be really a big challenge for any TH.

Best regards,

The process currently being used to mine gold is to have an excavator clear and dig through about 50ft of overburden about 1/2 acre in diameter to get to the gravel which contains gold. Its a hit or miss process, sometimes the pit gives 200 ounces or 20 ounces. Establish mining comapnies are restricted from heavy mining due to environmental issues. What I am looking for is a product that could even the odds in helping me decide where is feasible to work or pass over.
