Buried GOLD at Nome!

[geowizard]

Hi Guys and Gals!

I have been prospecting the Nome mining district for the past thirteen years. Although, yes I have set up a sluice box on East Beach, I decided to explore the district using a Geophysical system called DIGHEM.

DIGHEM is a "Frequency Domain" system that measures at several depths into the earth using electromagnetic energy. Check out my thread on "electromagnetics". The system is a commercial geophysical survey system and is not sold to the public. It is however used by major geophysical survey companies contracted by mining companies and governments all over the World.

I have been able to combine several tools to per-view DIGHEM geophysical data. My emphasis has been in the State of Alaska. I would like to share with you some of the results from GOLD mining districts in Alaska. The process of learning to interpret the data and employ the right tools is time consuming. Like metal detecting, it takes an understanding of the system and the tools to interpret the data.

I have made hundreds - possibly thousands of discoveries. I would like to share a few from Nome here on TreasureNet.

Stick around!

Very interesting! There was another thread on here about using microwaves to generate ( I'm assuming rf) harmonics in quartz that could be used to analyze quartz veins for gold. We love new tech. Just keep the divining rods out of it or you'll lose me fast lol.

This is the "Real Deal". No non-sense - No BS.

The place where TreasureNet and other forums go sideways with reality is where people wander off into pseudoscience and related unexplained - unexplainable "phenomenon"! Don't waste valuable time and money on non-sense and BS that's not backed by anything, not provable, not verifiable, and having no technical or scientific basis.

DIGHEM is a recognized de-facto geophysical survey system used by mining and exploration companies all over the world. It's time proven and tested!

It's repeatable. The survey data is checked at regular intervals by making a repeat pass over previous survey passes and the data is compared for repeatability. "Tie lines" are flown perpendicular to previous survey lines to check that the data repeats on points that cross the previous lines.

The system is calibrated. A calibration method using standard calibration coils and ferrite rods is used to establish settings for the gain or sensitivity/response of the system. The data is based on the same calibration from one survey area to another.

Millions of dollars are invested every day by legitimate mining and exploration companies all over the world. The science has been peer reviewed and documented by internationally recognized groups like SEG, and related geological and geophysical groups.

Please note, I'm not buying anything or selling anything!

My sole objective is to get Treasure hunters, Precious metals and base metal prospectors and exploration entities on a solid path with REAL examples of surveys done over the past several decades in Alaska.

A good place to begin is Nome, Alaska!

Stick around!

Its Truly amazing how much gold the Nome are has produced,and will produce

 

[RTR]

Are they still running sluices/long toms/high bankers on the beaches of Nome ?

 

[geowizard]

RTR,

Yes, however, abuses have caused added layers of regulation.

Thats a shame ,same old story everyplace

Nome was once considered the largest GOLD deposit on Earth.

From my work doing interpretation of conductive gold deposits and having discovered hundreds of them, I am wondering what to do. As unbelievable as it may sound, there are too many anomalies to go out, sample and dig in my lifetime. Ideas?

Thanks!

You don't have to dig them all. Just pick one and go get it.

 

[geowizard]

If it was that easy, I would!

There's a reason the Gold is still buried. Trust me, it's on my short term bucket list.

I'm working another project at this time.

Stay tuned!

Preparation;

It takes at least two years to buy materials, camping supplies, tools, 4 wheelers, then transport them to a trail head, one more season to cut trail, assemble a camp in the bush, bring in food and move in.

The Gold is buried. Even with the knowledge of where to dig, a plan to sink a shaft and build the associated head frame, procure timbers, cable, winch with a decent generator is time consuming.

Planning and prep time are needed steps in getting a mining camp set up in Wild Bush Alaska.

Stick around for more!

What I do;

I produce images of inferred GOLD deposits for prospectors. Nome is loaded with Gold.

Here's an image of a 12000 foot section of one survey line.

The black line is a graphic representation of DATA in the form of Phi (Phase Angle).
Less than 30 is a mix of gold/silver and copper. Less than or equal to 10 is Gold.
The scale on the bottom is 1000 samples. Samples are 12 feet apart.

Every sample has a GPS coordinate.

Same problem I have, plenty of targets!
I can't afford a rock crusher and chemical plant, or have it drilled, in some impossible spot.
I used to search everywhere, but learned it's better to spend most time searching in Free mill Gold districts, with large nuggets found nearby.
Out of the 20 t targets I've located, some were dug, some were just below the surface, and some slightly exposed, never seen by a prospector.
I located 8 Gold targets, in 2 days near Lynx Creek in the Bradshaw's.
Only 2 were below ground!
None were near, or on the creek, they are Ore veins not exposed by wash or river.

Dowser,

The Bradshaws are my old "stompin' ground"!
Probably dug around the same tree roots on Lynx Creek.

I tend to think of mechanical advantage related to the tools used to discover new gold deposits. The tools provide leverage for a mining exploration project or prospect. Prospects become closer to being tangible with evidence. A metal detector responds to GOLD. That is proven over and over every day.

With sufficient proof or evidence, the "probability" of Gold increases. There's only one thing left to do.

Dig it!

The Dig it part is where investment begins. Time. money and energy are hard won resources. They require a high level of certainty that the expected reward is an imminent reality. Otherwise there is RISK. That is where the investors lean forward to learn more! Their objective is a no-risk diggin' with a well defined outcome!

I panned a gram Nugget on Lynx, covered in merc it looked. My stepson dropped it back into the creek, oh well.
I had thought that extra proof might help convince. But the cost of a deep detector, or Gpr device, is too much. But might help someone believe..

Here's an image of a 12000 foot section of one survey line.

I would like to know how the phase is referenced. In metal detectors, it is normally referenced to ferrite which has a loss angle of close to 0°. Magnetic targets (including ground) fall in the quadrant from 0 to 90°, while eddy targets fall in the quadrant from 90-180°, with salt at 90° and a superconductor at 180°. But some people rotate and even flip the XR axes so that their absolute phase numbers are different, but relative to ferrite they are still the same.

The black line is a graphic representation of DATA in the form of Phi (Phase Angle).
Less than 30 is a mix of gold/silver and copper. Less than or equal to 10 is Gold.

How do you get this? It seems to go against the norms of phase-vs-conductivity.

The DIGHEM system is calibrated on the ground with a ferrite rod. The coils are compensated to 90 degrees. The Calibration is also done using a standard coil that gives a known response. Zero is done using air zero. In flight, regular calibration is done for air zero and standards loops. The system is calibrated for an internationally recognized test standard.

DIGHEM calibration
ensures the accuracy of helicopter-borne frequency-domain electromagnetic (FDEM) survey data by establishing consistent, reliable measurements of in-phase and quadrature components. It involves four key stages: primary field bucking, phase adjustment, gain calibration, and setting zero levels, usually verified daily.
Key aspects of DIGHEM calibration include:

• These procedures, often described in detail in technical reports (e.g., GM60573), are essential for producing accurate conductivity and resistivity maps for geological surveys.

Hand-held Metal detectors are not calibrated other than in manufacturing and by operator setup instructions to do an air zero and adjust the response for different soil conductivities referred to as "ground balance". Too many detectors to give a review of each method of calibration.

In DIGHEM, calibration is out of the hands of end users of the data. Suffice it to say the system is calibrated before each survey and on a daily basis or as needed.

Tie lines:

DIGHEM Surveys are composed of parallel survey lines spaced at 1/4 mile spacing. Upon completion of the survey, perpendicular lines are flown with a spacing of 3 miles crossing the previously flown flown lines.

Why?

To check repeatability! Tie lines crossing over previously flown lines SHOULD have the same response! The system is proven to be reliable "over time" and can guess the same answer twice!

Stick around, There's more!
