What Do You Think I Found? (2013)

Tortuga,

 

It was difficult to pinpoint with the 18, the 3030 and the pinpointer.

 

Funny thing is that I have used it since I found it in training.  I've taken it and some other gold and non-gold and covered them/hid them and had people swing on it with their coils and many can't tell which is the big gold.  PI's get so loud that everyone thinks it is trash.

 

I was told if I heard that big signal later in the day after many 50 cals I would have skipped this signal to.  I was glad to find it about 9 AM in the morning on a cool day.

Ah ok, so initially it was a boomer, like trash. That was a pretty deep hole too, but then again that was a big coil and a big piece of gold.

Holy buckets!!!

So, if most gold diggers are ignoring these  trash sounding targets, there will be big pieces left yet for me to find with my 20 year old MXT?

Sure is pretty, and how do you tell how much AU is in the rock?

A calculation is made using the air/dry weight and then the weight of the specimen in water.  This takes advantage of known specific gravities for gold and quartz by themselves.  It is an estimate.  Quartz and gold vary from place to place but it allows you to estimate the gold content.

 

I used a more 'simple' method at the time I found it.  I looked around for a piece of quartz that was about the same size.  I weighed that and subtracted that weight from my specimen weight.  It was within 5% of the later calculated value using this method.

 

Specific Gravity Tests For Specimen Gold

That is a real beauty, nicely rounded and great photos! Thanks for sharing them and the story and the specific gravity test page (one of the better on the subject).

There's a picture of this big specimen in the latest GPAA magazine "Gold Prospectors".

Pretty cool
