Well, your point might have legs if these three had seen the mine. Did they see the mine, or are they just repeating what Waltz told them?
I discount the stated completeness of the UA collection, or any other, pure and simple. With no public access to the samples/data, what good is the UA stockpile? [By the way, wasn't Waltz's candlebox alleged to have contained a couple hundred pounds of rocks? If so, I wonder how much variation in ore characteristics existed across the various pieces? Wouldn't it be interesting to find that different pieces in the box didn't match each other?]
I'm ambivalent about the Waltz mine's existence. With no reliable evidence (IMO) with which to make a judgement, all I can say is that it's a darn good yarn, but way too lacking in any substance to pursue seriously. I think the old man may have simply had a stash of highgrade ore that he obtained prior to moving to Phoenix. Many have strongly disagreed with my opinion. So be it. If I wanted to chase a rich lost mine rumor, I'd be more interested in something like UncleMatt's Lost Carson mine in CO.
Steve sometimes you surprise me. Have you not read any of the books, articles etc on the LDM? If you do not know the answers to these questions you just posed, then you may benefit from re-reading the accounts.
You can certainly discount the "completeness" of the UA collection all you wish - it never said that it had EVERY POSSIBLE source of gold on the planet. You are looking at it like an absolute or nothing. The letter shown to Corbin and Kollenborn simply stated that they had samples from every (known) mine in ARIZONA and the sample did not match any of them. Unknown source. If someone finds a gold deposit TODAY and wants to know for certain that it is or is not the LDM, a comparison can be made.
You are welcome to your own opinion about the LDM being a "yarn" and not enough substance for you to pursue. Good for you - and
I wish you luck on the Lost Carson mine, I really do hope you find it. And please post some photos when you do, I would like to see it and am not being sarcastic in saying that.
Azblackbird - thank you for the kind words! You will need to lay out a grid on your claim, space your samples at least ten feet apart and start taking samples all over the claim, following your grid. If it is a placer claim, you will need to pan out samples from each spot (rather time consuming but is very important information). Write down the panning results for every sample including those that have nothing, and be honest because a buyer will not be happy with you if they find out you fudged the results. Mining companies do not expect that every square foot of a claim is loaded with gold, they know that some parts will have little or nothing.
It would be best if you can dig or drill to bedrock (for a placer claim) or you will have to drill core samples in a grid pattern if it is a lode. This can get very costly and a mining company will want to see assay results on every core sample. Alternatively if the cost is prohibitive, you can chip out samples by hand and a few "grab" samples of the visible ore from the grid, and just crush the samples and pan them out, and of course keep a record of all results including the negative ones. Make sure you get the GPS coordinates for every sample you take, and write that down with every test result.
Photos of the vein or placer ground are helpful and if water is readily available or nearby is a good thing to show. Most mining requires plenty of water and if you have power near by that will be a plus too. If this is a placer claim one piece of information that is important is how deep to bedrock (if you can dig to it or drill to it) and where you find the precious metals, and how thick the paystreak is. If the paystreak is discontinuous and spotty, that should be disclosed too.
Before you list the claim for sale, be sure to check at the BLM records office that your claim is not in conflict with any other active mining claim, even if they are a different type (lode vs placer) for this can lead to a lawsuit against you long after you sold the claim. Don't get alarmed if there IS some boundary conflict, but this will need to be resolved in court before you sell it. As a general rule, the older mining claim will pre-empt the newer one where boundaries conflict, but not in every case. In many cases if you simply talk to your neighbor (claim owner) it is possible to find a happy agreement on the boundaries without having to resort to courts at all.
In my OPINION the best place to sell your claims are in the classified section of the International Mining Journal, but there are many other venues available and some are even sold on Ebay. If you have good photos and have made a map of the mineralized ground, along with your best assessment of how much gold (or other valuable minerals you are proposing to sell) is really present, even if the values are not that great, you will have interested buyers. Make sure your claim is properly marked out according to state and federal laws, each state has their own requirements so there is some (minor) variation, or if in northern Canada follow the requirements listed in the relevant Act (either Placer or Lode) as they are fairly different from US requirements. Also make sure you have the correct Township, Range and Section for these are how claims are legally located not just by GPS coordinates although GPS is nice for most people, it is not what the law requires.
If you have any geologic reports that cover your area where your claim is, or any history of it (previous owners, previous production if it was a mine at one time etc) this information is always a selling point. Even old newspaper accounts that mention your mine have relevant information that buyers could be interested in. If you can afford it, you could hire a geologist to spend a day examining your claim for his written opinion, this is expensive but not that expensive and can increase the value of your property by having an "official" or educated estimate on its value rather than just from a prospector. On the old geologic reports and history, even if these are on adjoining or neighboring mines, it is relevant as it is a fact that very often veins can run for considerable distances or be discontinuous, and crop up in nearby areas due to faulting, slipping of bedrock etc. So if your neighboring mine had a huge production, while this does not prove that your claim has the same, it is a good indicator that your claim COULD have similar results.
I hope this helps you a bit, there are quite a few others here with many years of experience and some with far more than me (Real de Tayopa for example) so you have a pool of knowledge available at your fingertips. Good luck to you and I hope you find that your claim is SO rich that you won't want to sell it!
Sorry for the somewhat off topic portion there, and I am sure many others here can offer advice and tips equally good or better than these suggestions.
Bill - I like the ordinary spectrographic analysis, which is also pretty accurate, but not perfect either.
