What Is the Average Grade of Producing Gold Mines?

October 5, 2012

Check out the awesome infographic below!   It a shows how rare +2.0 g/t Au deposits are and that the average grade of producing deposits is 1.06 g/t Au.

    Great to see Caspiche. Long on this one – don’t like the price now but someday it will reward handsomely. Got in the high’s of $2 and been accumulating slowly. Grade is not spectacular but can’t ignore the fact it has so much gold in the ground and when all said and done – if there ever will be a mine – it will produce around 2000 ounces of gold daily for two decades.

      Hi CaliJoe,

      I do agree with you; however, some folks don’t.

      We will see.

    Dear Al,
    I do not like snow or snakes.
    Which mine(s) should I send an application for employment to knowing the above?

    Hi Al, nice to see what people call alot of gold is today. Though its looks pretty low for me, in so many grams per ton figures. Different strokes for different folks is what`s its all about. Though during the CA gold rush having 1-3 oz per ton was super good back then though. My chemical extraction process is good for me, getting it to market is where the problem lies. I`ll be incorporating pretty soon, then I can get my metals to market with a good secondary refiner. Right now I`m incorporating my contractor`s lic. # as a C corporation, then down the road as an S corporation with a partner, while still maintaining my original lic. #, inactive of course. Using my Lic. to jump start my mining/refining business. I don`t want partners as a corporation(closed corporation) only to get around the Patriot Act for doing business as a mining company. The troubles one has to go through to make money. The ore concentrate is really valuable, its got a lot of Iron in it 76% which makes it good for the leach I use for processing it. As the Iron goes into solution the gold, silver, Pd, Pt, salts go into the solution as well. Thiourea which is an organic leach coupled with H2SO4 acid, the Ferric Iron(FeIII) which acts as an oxidizer works well with the Thiourea. Though at the end of the process when formamidine disulfide has finished its course at a pH of 6-12 formamidine breaks down to cyanamide and elemental sulphur which has to happen to get the gold out of solution using stabilized form of sodium borohydride. In obtaining the precious metals using potassium permanganate coupled with H2SO4 causes the causes the salts in the liquid to go into solution, then I apply the SBH(sodium borohydride) resin the salts become metals instantly. Its wonderful obtaining precious metals chemically when you know how to do it. Its taken years to having done it. Its kind of what they say about Ron Paul that one word describes him being “consistent“. Having a process that has consistent framed into it, is what a success can be. Producing from this ore concentrate 2.33oz of gold per pound, .66oz of Pd per pound makes what others that have a 401K or a retirement pension fund have. Its sure a good time to have precious metals in the ground, when all hell is raging above the ground.

      Howdy Dennis,

      Please send me some material on what you are doing in California. Send it to

        Hi Al, do you want some of my ore concentrate, it looks like black sand, but is color is purple. Its quite hard to fire assay. If you assay it, just typically you will get only 0.4oz. of gold per ton. At least what others that did the assay on it did to it. It acts like a telluride type ore, though it doesn`t have tellurium in it. If you do a reduction assay using hydrogen the gold will be there. I had a guy from MineX look at it, he used a hydrogen furnace on it and produced gold, but was really shady, wanted the location of it, probably wanted to steal it from me. The chinese wanted 3 metic tons per week through MineX, checked him out on the internet, found him being sued by numerous people on the web, that was many years ago though. As you know when I talked with you several years perhaps ago I told you that I`ve been working on this material since 1985 to break it chemically, so its a tough one to get a handle on it. I found it back it 1983 just walking around, then came on a camp fire with some boards partially consumed in the fire – wood, it was cold when I came upon them. I flipped them over and found what looked like gold on the backs of them. I was really hooked later on while in the back yard experimenting on some wood and some of this material, then I quite by chance produced a gold bead on glance it was hard, but soft metal bead. I was in love. Yes hooked on this ore. In 1995 produced 10.25 grams of 80% precious metals from some 2 Lbs. of ore concentrate. Sold it to J.M. Ney just 8.25 grams of it and produced 3.141 oz. of gold, 1.775 oz. of Pd, .07 oz. of Pt, 1.148 oz. of silver, it was my 1st check.

          ooops. thats 10.25 ozs. of which was determined to be 80% high grade precious metal content, sent J.M. Ney 8.25 ozs. was paid….

          You have a great passion Dennis F!

          Where are you located (general location not specific) in California?

          I am asking because we get down there probably 1/2 dozen times per year and it would be fun to get together.

            I`m just a nobody, a bit of an eccentric I guess, only have a few friends. Bill Earnshaw is a miner friend usually doing things like me, but has been hard rock mining for 35 years or so, since he was in his early twenties, we worked together in 2007 down at his place around the L.A. area, he`s not there now mostly in AZ working on Silver & Gold. He goes to Mexico, all over the western United States, he`s really knows how to assay complex and otherwise difficult ores. Bill thinks my ore is valuable too, but not as much as I think it is. He thinks its only 2500 – 3000 ozs. of gold per ton of the concentrate. He`s only work on some that had some 200 ozs. of gold per ton before, but he`s not into chemicals like me. Bill thinks my ore has Rh in it too, but Ag does some of the same things to itself as does Rh. In the “F“ deposit, I had it assayed by another Assayer and he came up with only .494 oz. per ton on that ore, not my “MS“ ore. He used a microwave technique, oh yes just remembered his name Greg Iceman, may have to look it up later and tell you the correct spelling if you want of his last name, well that sounds like it. I don`t live in L.A.. I live near San Jose, CA. Some day I`ll have to return to my roots near Redding CA. Perhaps Old Shasta, near Redding where there`s hard rock gold to be found. I found a lode gold deposit up there in 1983, before I came here. I always look for lode deposits never placer deposits……More rambling….

            Let’s try and get together when I am in San Francisco for the Hard Asset Conference.

            Let me know if that works.

        Hi Al, you probably want only some literature, SORRY about the rambling on of me its late morning, I`m tried….

          Rambling is valuable, Dennis F!

          I am very curious as to what you are doing down there.

    Dennis F:


    With ever decreasing grams per ton and ever increasing costs to mine(25% in fuel costs alone not to mention increasing labor and royalty expenses) why doesn’t existing physical make more sense with all of these costs already in the spot value? What am I missing?

      Oct 06, 2012 06:15 PM

      Hi Dai Uy, because at $1781.30 per oz. of Gold @ 2.33 ozs. per Lb. of ore concentrate & approx. $636 per oz. of Pd per Lb. of ore concentrate spells $8,300,860 per ton of this type of ore for gold; approx. $839,520 per ton of this type of ore for Pd, plus the Pt 1/5 to 1/4 oz per Lb. & Ag are quite alot in precious metals in my opinion for a ton of my ore. I`m a one man operation, I`ll automate the entire process. Using electricity, H2SO4 acid NaOH, SBH are about the only things that`s are pricey. But upon going to corp. will help with wholesale cost for chemicals.

    Oct 05, 2012 05:26 PM

    Not to mention 3rd party and difficult financing risks…………………

      Oct 06, 2012 06:23 PM

      Perhaps for you and others. If and when I buy into what you guys do, sure its going to be bad, if the people doing those low amounts precious metals per ton ratio is the factor, why yes its a problem. Its like driving a car, then its fixing the car, but you only just drive it, not fix it.
