    Reno Chris got a reaction from wade95 in Beware Of Phony, Junk Metal Detectors   
    Well, today (here in Africa) I got to see and play with my first phony Chinese knock off metal detector. I have heard of these things for years but never before had the chance to actually see and experience one. All of the more expensive detectors, and especially those which are targeted to find gold are the subject of thousands of Chinese phony detector stimulants.  If you are someone who owns or would like to own a metal detector, you should know about this. Let me tell you the story:
     
    At the moment, I am in Africa and our group had just completed dinner at a restaurant across the street from the hotel we are staying at. I stayed at the restaurant for a few extra minutes transmitting an email because the internet at the restaurant café is notably better that the one at the hotel in which I am staying. There are some detector dealers from this
    part of the world with us. As I was returning to my room, I saw one of the guys in our party putting together a GPX 5000 out by the Hotel pool, so I walked over to observe what was going on. He told me the customer complained his GPX was not working, so because I own one of these detectors, and know how to operate them, I tried to lend a hand figuring out what the problem was.  We first tried a nugget I estimate was about 3 to 4 pennyweight in size.  It should have screamed, but it gave no response. They waived a beer bottle cap which happened to be on the table and it no response. I finally waived my cell phone, a Samsung Galaxy note 2, perhaps the biggest cell phone currently in production, filled with lots of metal and I bet equivalent to at least a 3 ounce nugget. Nothing – no response whatsoever, even though it was almost touching the coil.  We didn’t try any larger targets like an engine block or anything because the settings were fine and something was clearly wrong.  I offered to go up and get my GPX 5000 control box because I knew it worked and we could figure out if the problem was in the coil or the control box. I returned with my box a couple minutes later, but they had already figured out the problem. The customer had not actually purchased the detector from the legitimate dealer he was asking to help him, but from some other supplier who promised he could get a GPX 5000 from him for a few hundred cheaper.  The customer had visited and spoken with the legitimate dealer, so the dealer actually remembered him, but in the end had purchased from another supplier, which is what they found out while I was up in my room. The bottom line is that the poor customer had paid nearly $5000 for a worthless piece of junk that looks exactly like a real detector but is not.  


    There are many thousands of these phony detectors out there, and it’s not just Minelab – its other makers too. If you buy a new detector of any brand – buy it from a trustworthy company who will stand behind their products and even so, test it out in the store before you buy. If you buy used, make sure to test the unit first. If you get a story that its broken but the
    manufacturer can fix it for you, decline and tell the seller to get it fixed himself and once its running right and you can test it to prove that, then you would be interested in buying. These junk detectors are selling all over the world and many are being burned, even in the US and Europe. Don’t let yourself be one of the folks who are stuck with an expensive piece of Chinese junk.

    Torch assays can be a rough,ballpark type of tool in estimating precious metals concentrations. They will not be accepted by companies looking to purchase any claims you have staked.

    Reno Chris got a reaction from David Cox in Lithium Needs vs. Burning Man   
    A little bit of humor here:
    I read in the local paper that a Canadian Mining company has staked lithium claims all over the dry lake bottom (playa) where the Burning man festival (party) is held each year. Now the Burning man folks are very left wing (the event originated in the Bay area) and anti-business, anti-mining. The event is sort of the modern day equivalent of a pagan orgy. Its quite funny to me that the need for more Lithium for high tech batteries has caused the alkali flat playa where they hold the event to be put under mining claims. Attendees are already up in arms that Burning man could be at risk.

    Reno Chris got a reaction from Robert P Miles in 1/3 Ounce Of Nuggets From Northern Nevada   
    Here is a bit of gold I have got on a couple recent trips to the northern Nevada goldfields - Been a really wet last 6 weeks or so up this way with thundershowers and lightning on many days. The total weight for this gold is about ten grams, or roughly 1/3rd of an ounce. The bigger pieces were found with Minelab's GPZ 7000, while the smaller stuff, mostly to the right side of the photo, was taken with their SDC 2300 - both very definitely have their place for the types of detecting I do. I've had rain shortened days prospecting where I had to sit in my car and wait out a storm, etc. and some partial days that were spent with some time prospecting but some time driving back and forth to the gold fields and later returning home. I'd say this gold represents the equivalent of about 5 full days of prospecting.

    I wish I could claim the biggest piece was some faint warble of a signal that I had the talent and skills to hear and identify, but it was a loud booming target less than an inch deep that any metal detector could have heard. When it boomed through my earphones I was sure it was trash, but I dug it and in much of northern Nevada there is not a lot of trash. The second swing of my pick a dirt clod flipped over and the big nugget was shining back at me. That was a nice feeling!

    Good gold is still out there, it just takes some work, persistence and a bit of luck - and sometimes you need some patience while waiting for the thunderstorms to stop.

    Reno Chris got a reaction from Rick N in More than one way to make money prospecting   
    There is more than one way to make money prospecting. Leasing out prospective claims to mining companies is a subject I have written about in the ICMJ and also in my book on prospecting. People have made big money doing this - a lot more than this check. Its a serious effort.
    I am publishing this check with critical areas blanked out for security reasons. I also altered the colors of the check, the company who issued it is out of business and I am guessing there is no significant money that is left in their account. So all things considered, I figure its safe to show. As one can see from the date, the issue was two years ago in 2015. I'll get my 2017 payment in a few weeks from a different company.

    Reno Chris got a reaction from zaqqaz22 in Parts Per Million.(Ppm) Vs Grams Per Ton.. Does It Stack Up?   
    The key to the effect of mixing two things together, volume or mass, is a significant amount of both materials in the mixture - if its essentially all one or the other, the properties will be of the one that is the majority. 
    If I add a tiny bit of tobacco smoke the size of a green pea into a house full of air, you will not smell any tobacco. If 10 smokers smoke 10 cigarettes each in a sealed house, you will smell the smoke.
    If you put one tiny grain of salt from a salt shaker in a 5 gallon bucket of water, you wont be able to taste the tiny amount of salt. If I put 3 cups of salt into 5 gallons of water, you will be able to taste the salt.
    If I mix 1 ppm (volume or weight) of gold into a million parts of quartz, you wont see any change in density of the mixture.
    The fact is that one PPM is a very tiny, tiny amount. Hard to grasp its so tiny.
    The method you were using to figure combined density is wrong and cant yield a correct answer, weight or volume.

    Reno Chris got a reaction from zaqqaz22 in Parts Per Million.(Ppm) Vs Grams Per Ton.. Does It Stack Up?   
    No. Its done as an ounce (weight) per ton or gram (also weight) per ton.
     
    Since its done on a weight per weight basis, no conversion of something else to weight is needed.
     
    Since virtually all metal analysis is weight per weight, then yep, a gram of gold is the same weight as a gram of scandium or a gram of silver or a gram of lead, etc. A gram is a gram.
     
    Actually analysis for gold are normally done in parts per billion, and one thousand ppb is the same as one ppm. An error of one ppm is really large and does not happen. Also, lots of samples are taken and the results are averaged, so the error of one sample is minimized. .
     
    So if we are looking at the PPMv of CO2 in a stack exhaust, then yes gas analysis might be done in volume, but we were talking about metals, not gasses, and not all analysis of all substances can be assumed to be exactly the same.
    Metal analysis are done as a weight per weight because prices paid for metals are weight based. No one buys a cc of gold, you buy an ounce or you buy grams. Manufacturers don't purchase a liter of copper, they buy pounds or tons of copper. The difference is important.

    I'm not sure what you are trying to represent with you math - that's not any way to calculate density. What you are trying to do doesn't make any sense to me.
    Adding one gold atom to one million quartz atoms will make a change so small that you cannot actually measure it in terms of density.
    It would be like adding a drop of water into a bucket full - you wont be able to measure the increase in weight from the extra drop on any normal weight scale. 
     
    it could be done perhaps this way:
    For a million parts quartz and one part gold
    (1,000,000 x 2.7 - quartz) + (1 x 19.3 - gold) = 2,700,019.3
    2,700,019.3 divided by 1,000,001 parts =  2.700017 grams/cc
    so your 2.7 density sample with one part in a million of gold added is now 2.700017, a change so small that it virtually cannot be measured by any normal density measurement. Like I said, a drop in the bucket, a change so small you cannot measure it.
     
    Calculating the gold part of a gold-quartz sample by density really requires that the gold be in the range of 10,000 ppm - the same as around 1% by weight. If it gets much less than that the density method is just too rough and inaccurate that any numbers you get just don't mean much.
     
    You are correct that 1 ppm equals in an approximate, rough way 1 gram per ton or around 0.03 ounces per ton.
     
    1 ppm is one ppm by weight, so one ppm of scandium or gold are both one gram in a ton, as one gram gold is the same weight as one gram of scandium.

    Reno Chris got a reaction from Ronald C in True Cost To Mine Gold - Companies Under Pressure   
    This is very true and few small miners take these costs into account when figuring their costs. You may have a fuel cost of $200 per ounce, but when you consider maintenance and repairs, lost time for breakdowns, money needed to replace broken equipment, costs to explore for and fine new resources, your real true costs are much much higher than the fuel cost of $200. Ignoring the time cost to do all the other stuff is just denial of the facts.

    Good point. If you are just doing it just for fun, then you keep on collecting nuts.
     
    If it is a business however, as the price keeps going down eventually its cheaper to buy your nuts at the store then work to find them yourself.
