THE POTENTIAL OF WHAT MAY BE COMING FROM DRILL RESULTS!!!!My source of info is from this web address which is a copy of an old book from the University of Arizona. It is called the Geology and Ore deposits of the Oatman and Katherine districts of Arizona. Someone has photocopied the pages and posted them on line. Please read it for yourself too. It should give you an excellent understanding of what may be to come. You will get a fairly good understanding of where the drills are at now, what has been found and what excitement may be coming from the results of deeper drills.
Here is the web link to the book

The 1st through 4th stages I believe we have seen in the previous drill results.
Stage 1 around 1 gram per ton
Stage 2 around 1-2 grams per ton
Stage 3 around 1 to 12 grams per ton
Stage 4 around 6 to 32 grams per ton
Stage 5 around 32 grams per ton and up.
It appears that stage 5 is at the basement of the vein and the primary host rock is yellow quartz, Calcite and Adularia. All three usually host the high grade gold deposits.
I believe that the present core drilling will be in the stage five zone in what is termed the Boiling zone. The RC will be in earlier stages. The stages table is on page 72 of the book and a description in detail of the stages begins on page 63.
Past high producing mines had their best values up to 800 feet at United eastern mine and 600 feet for the Tom Reed extension claim where both were mining 1 oz per ton plus gold in stage 5.
Again it needs to be noted that the posted mining results in the book at $$$ per ton. $20 was the going rate per ounce of gold at that time.
