6/27/20 Report - Mining Sampling Techniques. Mismarked Gold Ring. Turtle Barnacle. Some Beaches.


Written by the TreasureGuide for the exclusive use of treasurebeachesreport.blogspot.com


John Brooks Saturday Morning.

The beaches are really building on the front..  You can still see where the water  had removed sand farther back on the beaches though.  The water hasn't been high in quite a while.

You could see the haze created by the Sahara dust.

I also went to Fort Pierce South Jetty.  There you could distinctly see the hump on the front beach where new sand had piled up in recent days and weeks.

I'd love to see a lot of that sand washed out.  Good detecting spots are scarce, but the dry sand areas aren't bad due to the increased numbers of people at the beach during these hot days.

Found this Turtle barnacle.  Interesting creature.

Concerning the ring I posted yesterday that was marked 14K but seemed to test 18K, Pavo offered the following thoughts.


"Ring appears to be marked wrong, odd one."

His electronic tester is off the mark most likely answer...calibration,  weak acid...something. 

The hallmark and maker mark appear laser cut, not dubious as he implied. 

It could be a half carat high (14.x)  as some  high quality makers do.  (The plumb mark itself seems to have fallen out of fashion).

An extra half carat or so could contribute to the apparent tester error...


I've given up on testing gold myself.   I used to do a lot of acid testing but don't bother with that  anymore.  Handheld XRF analyzers are easy, non-destructive and accurate.  You can get it done almost anywhere.  XRF analysis will also tell you the alloys, which might be helpful.  I'd advise having it tested at a jewelry store or pawn shop.

Acid test kits often come with pen kits tipped with gold of various purities.  You rub the 14K, 18K or whatever purity you want to compare on the touch stone and compare how the acid affects the gold of known purity compared to how it affects the streak created by the unknown item.

Good to have all ideas for consideration.  Did you notice how we accumulated information concerning Fort Pierce casino from different people over a few days, adding a little more info each day until it seems we got it pretty well nailed down.

Slowly going through the information gathering process is leads to more complete understanding and assimilation than just receiving a simple unquestioned answer.

Have you found incorrectly marked items?   Any other thoughts on Duane's ring?  What do you think might be going on?

Deduction moves from theory to experiment to validation, where induction moves from observation to generalization to theory. Deduction is harder to use outside of lab/science settings because it’s often hard to find a set of fully agreed-upon facts to structure the argument.
That says that induction, most used in complex real-world settings, ends up with theory, while deduction ends up with validation.

You can apply that to a lot that is going on in the world today.  A lot of people are mixing up theory and fact.

Yesterday I tried to discuss sampling procedures for the beach and didn't really get very far.  I'll try to address that better some  other time.

In the mean time you might be interested in this information on mining geology sampling methods.  It is not exactly what I was talking about yesterday, but there is some very relevant information if you are willing to scan through it.

Here is the link.

There was a lot of fishing going on at the beach this morning.


There are no developing storms in the Atlantic. Supposedly the Sahara dust storm is suppressing that.


It looks like we'll have nothing more than a one or two foot surf for the next week or more.


Happy hunting,
