This is very nice example of the point we had. Some sorts of hematite look completely analogous to this. Also pyrite, I have seen similarly structured antimony/tetrahedrite ore (very strange)... Some had gold, some trace gold, some no gold, some had silver, some were completely PM free.No. 7 is molybdenum ore from Nevada. Its nice and sparkly with moly sulfides and looks good, but has no gold or silver.
No means of educated guess could resolve it, aside XRF or proper assay.
O just recently started processing granite ore of all types, PGMS, Iron ore with gold, Platinum, and iridium ore, which I think maybe it's a meteorite..Its so wonderful to have found someone as knowledgeable as you are! Just to confirm your extensive expertise, I have attached 10 pictures of some rock. Can you well me which of these have significant gold? I actually know about all 10, so I know the correct answers from testing and assaying, but I am sure you will get 100% correct! Please let us know your determinations. Just a hint, there is no visible gold in any of them, though some are very rich in gold.
OK, Rick I am seeing your Amazing Skill Set did not stand up to the test.Sample #1. The samples of hematite enriched material similar to this that I have assayer has never been any less than 1/5 of an oz per ton gold.
#'s 6, 7 & 10 are my other choices for most likely material.
Sample #7 would be suspect for silver and possibly pgm's.
#'s 2, 3 & 5 would be secondary choices with expectations of silver being dominant.
There, I answered your retort. Let's see how I scored.
Did not mean to come off as rude. I do know the difference in certain ores and am always learning. Yes I've done acid test fire assay and oxidation.OK, Rick I am seeing your Amazing Skill Set did not stand up to the test.
No. 1 is gold ore, but only 2 grams a ton, so less than your "never less than 1/5th of a ton"
6 is gold ore, but 7 and 10 have no gold.
7 is moly ore, with no silver or PGMs.
2, 3 and 5 are rich gold ores, all with very little silver.
I would say that you did not confirm that you could look at ores and just tell if they were good or not.
Can you help with what this is?Just had a brilliant idea. Lets let people post pictures of their metallic alloys. Then we can have a $ 5-10 pool to guess which one has gold or silver, or whatever.
I would say calcite on limonite.Can you help with what this is?
Why would you hire a prof exploration geologist, if, a seam was found and curious if it contains value?At least put a couple of drops of white vinegar or HCL on it to see if it fizzes. Fizzy = Calcite, no fizz, more than likely quartz. If you can't assay it yourself, then farm it to those who can. If it is a single piece of float, put it in the rock garden. If you found a seam of it and interested to see if it has any value, hire a professional exploration geologist. Orrrr, spend the rest of your life hooked on mining, processing, permitting, refining, etc..
If you value your time, you will take my advice. Mining a deposit is a very expensive proposition. You still haven't answered the basic question as to the sample you submitted being either an in place seam, or a single piece of rock laying on the ground that you found. You obviously haven't been on the forum long enough to read some of the comments on rocks submitted via a picture. Please read them. A rock picture can in no shape or form be analyzed by a picture. It requires chemical analysis. No one on here ,with any credibility, will give you an answer, other than "looks like a rock". This is because we mean business when it comes to the subject of refining, being the initial concentration of ores, to the final refinement into purified elements. It is actually offensive to do what you ask, to this forum. Please read a simple book on geology, minerals, assaying, etc.. We cannot solve the worlds problems, if they refuse to help themselves. If you don't help yourself, then pay the guy/gal who can give you the answers to your questions. That is what I mean by hire a professional geologist if you want answers now. You obviously think you may have something of value, or you wouldn't ask about a rock composition on a Gold Refining Forum format. Almost all members on this forum have answered questions about a rock picture, much to their frustration. I think this is the last time I will comment on another "rock" picture. It sucks too much energy out of a forum designed by professionals for beginning to advanced refining, not geology 101. You may be lost, but to find yourself, YOU must learn to help yourself, become the sponge of knowledge by reading and experimenting about the subject. When you have a question about a certain procedure, feel free to ask here, but please read the many valuable posts on the various threads that abound on this forum, to see if it has already been discussed. It probably has, as this is a very knowledgable group covering just about every facet of the industry.Why would you hire a prof exploration geologist, if, a seam was found and curious if it contains value?
I'm not following why this is what your thoughts are as the only 2 suggestions you mention for "wanting to know if a vein had value". Please explain for those of us who are lost and relatively new to this.
Rick: I can't find Geotech Analytical using an Internet search. Do you have a website or some means of finding you so that someone can send you samples for an I.D. or assay?Hey Chris; are you ever going to post an answer stating which samples contain precious metals?
Your hesitation to post such makes it seem obvious that you just ate a truckload of crow with your snappy reply.
We all want to see the answers.
You should have posted those ore photos with the assay results long ago for the prospecting community to have learned from.
As I said before; "Once The Rockman", Always The Rockman.
As McArthur once said; ..."I have returned."
I am not just "Another Rockman" on this forum, I am "The Rockman" of this forum. Nuff said.
Thanks.Welcome to the forum, though I see you've been here for a while, and thanks for the link.
Rick & Carrie haven't been here for quite some time, so you probably won't get an answer. If you're using a computer, you can move your cursor over a member's name or avatar and see when they last visited. If you're on a phone, I think you have to click on their name to see it.
