In The Area You Hunt How Many Nuggets Does It Take To Find One At 10 Grams Or More In The Area You Hunt ?

Some places have nothing but small gold, and you could hunt for ten years and never find a 10 gram nugget.

Yes…I am intimately acquainted with many places like that :ph34r: :laugh:

If the area is known to produce larger nuggets, then pick spots that are full of trash, like many streams here in the Motherlode. Where there is trash, there is also likely gold still remaining, since trashy area's are usually avoided by detectorists (hence still tons of trash around). However, you need to have the stomach to detect in these areas, it can literally drive you insane. However, in case you indeed dare, the average for me is probably 100 pieces of trash for one nugget, including potentially bigger ones, but only very rarely > 10g size. On the other extreme, if you wander through a gold bearing desert, like a club claim, and you absolutely get no signal, then it has already been cleaned by other detectorists and you are too late to the party. Of course, you can try to be better and catch what they haven't, with better techniques and better equipment. Just don't go where JP has gone before 😉

Had a good run right up to the cans but had to stop here.

A very familiar picture! That definitely exceeds what I can tolerate. What I mean by "trashy" is more the invisible trash that you dig up. But yeah, if I have a hard time anywhere putting my detector down without my ears being blown away then it's truly hopeless. Unless you have a dozer to clean up first.

We tried the rake but no good as there was to many small flakes as the ground was less than 6" deep the grader would of been no use. By the way the location was remote that the fuel for a bull dozer transport was out of the question an there were two large rewarding patches that I found within an hour of walking distance that needed our attention. These did not have many bits in the 1/4 to 1/2 oz range but some larger specimen more than made up for that as most were around the plus or minus gram size.

I live on the Far South NSW Coast AU and we mainly get the smaller nuggets in the 0.5 - 2.5 gram variety in the state forest around home.  Last year after the fires went trough here the bush just opened up and revealed gullies that I didnt know existed, even though I had worked that area many times but were hidden by the thick undergrowth.  In that window some really nice pieces came out in the 10 - 25 gram range with some lucky prospectors picking up pieces up to and including an ounce. 

Most of the gold here is through secondary alluvial deposits and reef gold.

This is how I would answer your question in fishing terms.  If you want to fish for sunfish (Bluegill and Crappie), go to well known areas they are being caught and fish...then that is usually what you'll catch.  If you prefer to fish for 2 pound rainbow trout, do research and fish that area.  Chances are you'll catch some nice trout.  If you want to catch 5 pound brown trout, you need to go there.

In gold hunting areas.  All well known sites (such as Rye Patch, NV) the majority of detectable gold has already been found, but the tiny pickers are still there.  Even in 2021 I can find 20+ a day, but their sub grainers.  If I want to hit a 10 grammer, I'll pass up at Rye Patch and go to areas that have not been hunted as hard.  If I want 1+ oz'er, I prefer tailing piles in gold areas that had good size placer nuggets.  Research is the key to success of bigger gold.

At my stage of gold detecting career, I'll pass on 20/30 dinks = 1.5 to 2 grams just to find a couple bigger solid nuggets in the same day.  Now I have customers that are tickled pink with any gold no matter the size...and I am just as happy for them.

Hope this helps.

      You have had a lot of success over the years.  I imagine you have found some wonderfully large masses of gold.  Think about each of those for a few moments, especially those in the lower 48.  Does anything appear as a common feature of their locations?  Surely not everything would fit the same mold, but was there anything present frequent enough to indicate one location might be a little bit more likely to yield big gold than another?

      The Mystery Formation of Extremely Rich Gold Veins Might Finally Be Solved
      MICHELLE STARR 24 MAY 2021 Gold, for all its wonderful uses, isn't hugely abundant in Earth's upper layers. For each ton of crust material, there's an estimated just 0.004 grams of the precious metal.
      Yet somehow, there are regions that contain "bonanza" abundances - hyper-enrichment, in the scientific parlance. How these gold veins form in time spans as short as days from hydrothermal systems that only contain trace amounts of the metal has been a geological mystery.
      It's one that now has an answer, from the most unlikely of clues: the separation and clumping of fat particles in soured milk.
      "Scientists have long known that gold deposits form when hot water flows through rocks, dissolving minute amounts of gold and concentrating it in cracks in the Earth's crust at levels invisible to the naked eye," geoscientists Anthony Williams-Jones and Duncan McLeish of McGill University in Canada stated in a Q&A.
      "In rare cases, the cracks are transformed into veins of solid gold centimetres thick. But how do fluids with such low concentrations of gold produce rare ultrahigh-grade gold deposits? Our findings solve the paradox of 'ultrahigh-grade' or 'bonanza' gold formation, which has frustrated scientists for over a century."
      Milk is an aqueous solution made up of several components, one of which is microscopic globules of fat. At the pH level of fresh milk - very close to neutral - these fat particles have a negative charge, which causes them to repel each other.
      The souring process involves bacteria in the milk converting lactose to lactic acid, lowering the pH level accordingly. This causes the surface charge on the fat particles to break down, and the fat particles separate from the milk serum and clump together with each other via coagulation, forming a sort-of gross decomposing milk fat jelly.
      Williams-Jones, McLeish and their colleagues found a similar process when using transmission electron microscopy to study gold deposits from the Brucejack Mine in British Columbia. This is one of the spots around the world where bonanza-grade mineralization can be found, up to 41,582 grams per ton.
      It's long been accepted that gold is transported by way of fluid through Earth's crust. However, in order to reach the abundances found in hyper-enrichment zones, previous studies suggested that the gold may have been dissolved in high concentrations in fluids containing chlorides or bisulfides, and transported and deposited that way.
      The other possibility is a colloidal solution, with solid nanoparticles of gold dispersed throughout hydrothermal and geothermal fluids. Since the gold nanoparticles hold a charge (like milk fat), they repel each other. When the charge breaks down, the gold particles clump together in a process similar to coagulation, known as flocculation.
      This has been indirectly demonstrated in the past; now, McLeish and colleagues have observed how it actually happens.
      "We produced the first evidence for gold colloid formation and flocculation in nature and the first images of small veins of gold colloid particles and their flocculated aggregates at the nano-scale," Williams-Jones and McLeish said.
      "These images document the process by which the cracks are filled with gold and, scaled up through the integration of millions of these small veins, reveal how bonanza veins are formed."
      For this process, the concentration of gold in the geothermal fluids only has to be a few parts per billion. It flocculates to form a jelly-like substance, which gets trapped in cracks in Earth's crust to form rich gold veins.
      This finding suggests that rich gold deposits may be more common than we thought, and may have occurred in several other contexts than previous estimates had allowed for. If other studies and further examination can back it up, the research could give us a new toolkit for understanding and locating gold deposits around the world.
      "We suspect that the colloidal processes that operated at Brucejack and other bonanza gold systems may also have operated to form more typical gold deposits. The challenge will be to find suitable material to test this hypothesis," Williams-Jones and McLeish said.
      "The next step will be to better understand the reasons why colloid formation and flocculation occurred on the scale observed and reconstruct the geological environment of these processes."
      The research has been published in PNAS.

      I'm interested in any information on how gold veins/ lode deposits become offset and how to attempt to predict the amount of offset.
      Anyone have information on this?

      Interesting! Will be useful when we eventually have a colony there.

      So what caused it to break away?  Here is more on that theory.
    • By Steve Herschbach
      The earth has been warming and glaciers retreating for over 15,000 years. Almost everything in the part of Alaska I lived in was recently exposed by glaciers and been prospected the last couple hundred years. Glaciers are nature's bulldozers and they destroy and mix. The gold distribution in glacial material is generally random and sparse. Where water has had time to work glacial deposits new placers can form, but the short geologic time spans we are talking about usually mean small erratic deposits. The good news is that also means you can maybe find a gold nugget just about anywhere in glacial material.

      If you watch the video a second time and pay attention to the area that becomes Alaska you will see that Anchorage, on the southern coast, was buried under 3000 feet of ice not too long ago. The interesting part is northern Alaska is largely ice free. This is extremely important. The placers are much older and more extensive in Interior Alaska than in the southern coastal areas.

      The northern US was heavily glaciated and much of the material was pushed down from out of the north in Canada. I find glacial terrain interesting because glaciers have melt water running under them and along the edges, which form small oddball placers in the strangest places, and other placers are possible in the large outwash areas.

      I am discovering there was a lot more glacial activity in the Sierras than I would have imagined and so this is still very relevant for me prospecting in California.

      These links may not be for your exact area but all contain good information about glacial geology and prospecting.

      Great freebie article Gold in Kansas

      And a small related article at the ICMJ Undiscovered Placer Deposits in Alaska

      Really good stuff starting page 117 on Gold Placers of Colorado

      Placer Deposits of the Yukon

      Geology of Tertiary and Quaternary Gold-Bearing Placers in the Cariboo Region, BC

      Here is some really technical stuff for those so inclined Glacial Geology & Prospecting

      Glaciers of California

      A much more prospector friendly version can be had in an excellent but pricey book by Chuck Lassiter, Midwest Gold Prospecting at http://www.midwestprospector.com/book.html

      I have a copy in my library of the best of the best. It is a high quality book with color maps and illustrations and a no-brainer at about half the cost. For $29.95 you have to just love books as much as me as that is as much as the Chris Ralph encyclopedia and this book would be a chapter in Chris book. That said, I have never seen the particular subject of glacial region prospecting covered better and more understandably anywhere else. It would be the go to primer for anyone interested in the subject.
