    Sad day. My heart goes out to Jameson and his family. Sorry for your loss.
  4. Hey everyone, please don't feel disrespect by my post here. I am reaching out for any member who runs a hard rock mine. I have asked a lot of questions on this forum and had some good advice too. UNFORTUNEATLY I have also been given and read incorrect facts on this site that members have posted. First of all I'm obviously not an admin to this site, but I ask as a group lets not answer questions if we don't truly know the correct answers, or maybe; be more clear that what you are stating is your opinion or idea. I WOULD LIKE TO HUMBLY ASK THIS FAVOR: I am in the middle of getting my own hard rock mine into small production. As any of you may know from experience this a VERY VERY bumpy road from every aspect of this industry; thus why so many of us have failed before. I am really looking to connect with an individual, or individuals who has successfully been down the path I have chosen. I am NOT asking someone to hold my hand, but just someone who would be willing to talk to me on a personal level and educate me on some of your own experiences in dealing with different entities, equipment, problems and successes related to running a hard rock mine. Please share your knowledge with me I am a very active learner and will not take an opportunity to talk with you for granted. PLEASE SEND ME A PERSONAL MESSAGE THROUGH THIS FORUM IF ARE WILLING TO TALK TO ME. THANKS EVERYONE FOR YOU TIME AND I REALLY ENJOY BEING A PART OF THIS WEBSITE AND FORUM.

    Does Anyone Here Actually Hard Rock Mine?

    Sounds like a neat place Billy. So far, our operation is about the same. We use SDS hammer drills and buckets as well. We primary crush with a jaw crusher and then screen, then over size reports to the impact mill. We built a small electric screener to speed things up. Once every thing is screened we run it across our shaker table as well.

    Starting A Placer Mining Operation

    I would learn all the mining districts of interest to yourself. For anyone looking at ground knowledge of using the BLM's LR2000 is a must. To use the LR2000 you must understand how the PLSS (public land survey system) works. There are not many maps available using the PLSS (at least in my area). Google Earth is an absolute MUST now days; in my opinion. If you use Google Earth you can add 3rd party software to it, so you can view the PLSS data you need. So once you know the Section (sometimes 1/4sec.), Township, and Range of your area of interest; you can then input the data into the BLM's LR2000. Using the LR2000 you can view any piece of public land in America to see any and ALL mining claim history. You will also be able to find out the most important question at hand, if the land is already claimed or not. If the land is open, you can then prospect it to see if you want to place a claim on the land. Make sure you follow local state and county laws for prospecting. Getting used to the process between Google Earth and the LR2000 can be very confusing if you don't have someone to help you. With practice I have found these tools used together to be THE MOST EFFICIENT way to research ground you may potentially be interested in. If you need any help with it I would be happy to teach you those first two basics.

    That's pretty much my thoughts too. I wish someone would invent a chemical that did the job, and was biodegradable. Oh well I guess that's only to be desired. Multi-million dollar idea for who does though.

    Fine Float Gold

    Maybe this is a stupid question since the answer is probably no, but I'll try anyway. So is there any little secret people have learned to help keep fine gold from floating away so easily? I'm talking really fine gold, in the 300-400 mesh range. We run a 4'x8' shaker table with our material classified to -70 mesh, we are currently using Jet Dry added to the water. Any ideas?

    Ac To Dc Converter

    I work as a low voltage electrician; If you go the battery charger route, make sure you get a higher end one. Some of the cheaper ones have a high voltage/amperage variance, giving the potential to fry more delicate motors. Some generators also have a high variance in voltage/amperage depending on the working conditions and load. The Hondas generally do okay if you have a steady electrical load, but if your equipment has a lot of variance in amperage consumption that can create further stress on your battery charger and whatever it is powering/charging. Electricity can do interesting things if you don't have the proper equipment to regulate it. If you are running expensive motors and equipment from the generator, it might not be a bad idea to get a power conditioner. This is essentially an expensive surge protector with a lot of outlets and precise voltage and amperage management. You can get a good power conditioner from an electronics box store. I use them at work to power expensive home theaters and servers. If you use the power conditioner you can use a cheap battery charger from harbor freight. It all depends on how worried you are about frying your electric motors and electronics from the generator.

    Fine Float Gold

    Your saying an RP-4 catches 300-400 mesh gold? As far as I know those tables were designed for placer mining. I've watched that particular table run hard rock ore and it only caught gold that was in the 150 mesh range, and larger. Not to mention table was dialed in very well. I just don't think they have to working space to catch 400 mesh gold. Honestly very few tables are going to catch gold that small with an acceptable recovery percentage rate. Has anyone tried the "Clay be gone" from Action Mining? If you have tried and used it, would you say it was any better than Jet Dry? I'm guessing it's probably just Jet Dry purchased in bulk and put into a bottle with the label above. Some dish soaps contain random oils in them to keep your soft womanly hands. I would recommend never using a dish soap if you don't have Jet Dry available. Maybe try adding a nice scented bubble bath if you don't have Jet Dry; I'm thinking something with lavender would do the trick just fine. Just kidding.

    World May Run Out Of Minable Gold In 20 Years

    Interesting topic, it's also interesting following the price of platinum to gold per ounce. Gold has been worth more that platinum only 10% of the time historically. Platinum is an industrial metal, signaling a weak economy when it's price is below gold. Mineable gold? Of course it will run out, not in twenty years. If you research mining companies that trade publically you will find that there is more exploration happening that it seems. South America is a hot spot right now. There is several companies down there exploring new deposits. Nevada also has more than one public company exploring deposits. Ghana has seen a lot of activity as well. Our economy is not on the rise we would like to think it is. The banks are already signaling trouble ahead once again. With the Fed's interest rate as it has been for so long huge companies have been taking out bonds to buy their own stock to make prices rally; as they did all last year. Now the rate increase is coming soon so companies has stopped taking new bonds, and stopped buying their own stock. Hence why the market has suddenly gone sideways these last couple quarters. As soon as this "bubble" takes it's negative down turn, ALL metal prices and commodities will take a huge jump. Then all of the sudden gold will be big news again. So anyways the exploration hasn't stopped, investors are just in an economic cycle that is not favorable to the whole commodities market in general. I honestly think gold will see record highs once again within the 3-5 year range. Minable gold running out in 20 years? That is a foolish idea; there is many new projects underway. We all know it takes 10 years or so to get a hardrock operation into production. By the time our gold has run out here on earth (lets not forget scrap gold) the asteroid miners will have figured out a way.

    Does Anyone Here Actually Hard Rock Mine?

    Well here's something exciting since the hardrock forum is quiet. My partner and I stumbled upon boxes and boxes of core drill samples in our mine. They are from Canada's Kinross Gold Corp. All in all there is probably 1000' or so within all the different boxes. Who knows if any of the cores even made it out of the mine. I suspect some must have gone out. Every box is labeled with the location and tags on each core. We can then find the respective tag in the walls of the drifts. So now the process of carefully getting them out of the mine has begun, interesting how much more work it takes to get the cores out than hauling plain old ore. Now we get to assay all these cores and hope for some good results. I recently connected with a former employee of the mine in 1999; he says the place was assayed out to have 50,000 ounces. Then Kinross leased the mine and began further drilling. I assume the deposit was to small for them to keep an interest. But for us we feel we got a small leg up and are pretty excited. I will keep you guys updated. We also have a channel on you tube with a few videos showing a bit of our operations. Search Sampson Resources.

    Sulfides

    SSN is Saturated Saline (salt water), Nitric Acid. I won't mention the product name on here because it seems the administrators get a little worked up over things like that; but if you do a google search for "field gold test kit," the very first couple of results feature the kit. Be very careful to use the kit in a very well ventilated area, and make sure you get arm length chemical grade gloves. The acids involved will burn your skin and your lungs if proper precautions are not taken. For your testing containers never use anything other than plastic (not the brittle type), glass or ceramic. Do a lot of research, as much as you can. If you have any other questions let me know.

    Sulfides

    We have been testing ores from our mine with a SSN leach. We have sulfides present in our ore and the SSN seems to do okay. There is even an inexpensive test kit available that uses SSN to leach and stannous chloride as a color indicator. You can get the kit for $40. If you get positive results it is easy to make the leach yourself under the proper safety precautions. Then you can use zinc to recover the values.

    Bonding? Action Plan?

    Hey Everyone. I have been looking into bonding and so forth, and of course the information available on the BLM site is not real helpful. I am hoping/planning to place a 40ft. shipping container on my claim by early summer. The connex will have our mill/recovery, tools, generators, and a water tank. Do I need to notify the BLM of this? Will I need a reclamation bond? What are the steps I need to take to do this properly? Our recovery system is entirely gravity based. What difference does it make if I use a creek on the claim for water, or a closed recirculating system? As far as the BLM sees it. I really need help in this area, Thanks GUYS!

    Black Damp

    I understand black damp and unsafe oxygen is a real issue not to be ignored when working underground; especially when there is a lot of old rotting timbers. According to my research rotting timbers produce carbon dioxide. Please correct me if I'm wrong as this is a sensitive/life saving issue. When finding/choosing a confined space personal gas detector there is endless options. I have found interest in the msa altair single gas detector, but they do not have a CO2 model. I have found that there is not very many options in looking for a personal CO2 detector. I understand that there is many detectors that snuff for multiple gases but even so most of them do not test for CO2. Then there is the idea of using an O2 detector, but to my understanding is: there can be toxic levels of CO2 even with oxygen levels at 19.5% or more; thus making an O2 detector inappropriate. I am really trying to find a personal confined space gas detector that detects toxic CO2 levels, but not necessarily limited to. I have a current budget limit of around $500. Please inform me of your own experiences with this subject and hopefully any recommendations you guys can make. Like I said this subject is not to be taken lightly and is a matter of life and death. I am really looking for some advice from the veterans on this one. We are not using any explosives in the mine so our biggest concerns is existing gases in the mine.

    Black Damp

    Oh and I almost forgot Geo. If a person is in the process of reopening an abandoned mine; how are they going to replace the rotting timbers and re-shore the mine if you have to stay out. All I'm saying is people are going to do what they are going to do. Lets focus on how to do that in the safest manner. This is a hardrock mining forum category, so it's kind of ridiculous to say STAY OUT. None of us would be interested in hardrock mining if we just stayed out. Even more IRONIC, Geo; is you contradict yourself in they same topic a few post apart! First you say "Don't hedge on safety" now in your most recent post you say "my advice safety first." So which is it? Anyone can be an expert but not everyone can take minute and think and be a little more personal and realistic with their "expertise advice."

    Black Damp

    Okay so, Black Damp is a common term used in the coal mining industry. The term Black Damp IS NOT limited to coal mining. Black Damp refers to poisonous levels of Co2 (Carbon Dioxide) in a mine from decomposing organic materials (i.e.: rotting timbers in a gold mine). It is also commonly called Choke Damp, which is the same thing. There is many other sources for toxic gases that can exist it a mine. If anyone on here needs more information on any toxic gases and the levels at which those gases become toxic; I would highly recommend spending some time on the OSHA website. They have an abundance of good relevant information pertaining to toxic gases in mines, and confined spaces. If a mine does have a source of carbon dioxide, and there is also standing water, the Co2 can settle in standing water and become concentrated. If this is the case, disturbing the water (like walking through it) will release Co2 into a breathable gas which can be toxic. As a rule though, standing water does not have to be present in a mine for there to be toxic levels of gas.

    Black Damp

    Well I got the detector put in use today. I have really good air really deep into the mine. I fee like I AM able to get away with using the detector I already purchased! I am really glad that I know what type of atmosphere we are dealing with and I am pleasantly surprised. The highest level of co2 I encountered was only 1190ppm; very low! It's always a good idea to play it safely and I am glad I did. Now I can have peace of mind down at depths. There is still deeper places to go so there is still a chance of unsafe co2 levels.
  22. Sampson Resouces

    Black Damp

    Okay so first off, 30,000ppm is the very lowest of toxic levels; it would take a minimum of 30-45mins before unconsciousness was likely. The mine we have is still much bigger than we have even seen. We know we will need ventilation in the mine, but we don't know to what extent. We need a co2 detector that can read higher levels just to see what type of atmosphere we are dealing with down at depths and in underhand stope areas where previous miners were high grading. So for exploring reasons going into areas with more co2 than 9900ppm is not an unreasonable situation if you have a detector that you can set at an appropriate level to give you adequate time to leave to better air. What I am going to do though is test out the one I got tomorrow to see at what point levels do exceed 9900ppm. (assuming they do exceed) Then obviously it wouldn't be smart to be doing any work or sampling until full ventilation is put in or better detectors are purchased. Anyways bad advice Geo. My dad worked as a mine electrician at two large silver mines and he told me that in one year seven people went missing and died in the mine due to black damp and co2 filling the air in non ventilated areas (stopes and winzes). Safety should always be the number one priority when working underground. We are not naturally supposed to be inside the earth. It's dangerous with endless hazards and safety should not be taken lightly.

    Black Damp

    So I got the Co2 detector today, really fast shipping. I've been playing with it and getting it set up. Everything seems to check out okay. There is one main problem I am having is the detector, it only reads to 9900ppm Co2. I should've noticed this on the details of the product purchase; live and learn. I am still learning. Anyways, according to OSHA there is no short-term (ie: immediate) risks until levels reach 30,000ppm. Although it is not safe to work full time (40hrs. a week) in levels which exceed 5000ppm. The more expensive monitors I mentioned a few posts prior measure levels 0-50,000ppm. That's what I get for being excited over a deal too good to be true, my fault. I can see where this detector could still be useful, I think I need to buck up and get the Honeywell. Any other advice on the subject?

    Well I did a little research. The unit has an alarm for high co2 levels and good customer reviews. I just placed my order for the device. Should be here this Friday. I will let you guys know how it performs once I get it in use down in the mine. Thanks again for the link Dick.
