In this video we zoom in on the assay results that we received from ALS Geochemistry. We took samples from a mine that has tailings, dumps, and underground workings that we are allowed to explore and possible develop. We use our Olympus DP-6550 XRF, Evil Eye 200x Phone Mini Pocket Microscope, and 1200x Digital Microscope to help us identify ore.
During the fall months, we will put a climbing team together to explore the multiple adits and shafts on this property, and adjacent properties. According to the owner, there are many underground workings that we did not have time to explore on this trip. If all goes well, we will locate ore worth shipping to our millsite. Thank you for your support!

Really do enjoy this type of video with detailed sampling explanations. I have subcribed and will definately tune in again.

Thanks for subscribing! We just started this style of video. We have more scheduled in the coming months.

I was having poor XRF gun reproducibility with long hole percussion cuttings from one shot to the next. I came up with wetting them, tapping them to settle, pouring off the liquid, stirring the damp sample again, then shooting through the bottom of a polyethylene container to protect the gun aperture, and keeping the aperture moving during the 30 second shot. Shooting the sample damp dealt with gravity separation issues and the moving aperture averaged out nugget effect errors. My subsequent QR/QC analysis had high agreement with independent bench XRF. This technique would work well with panning and sluice cons. The tapping/draining gives you a consistent ~15% moisture content. This method allowed me to get reliable results underground for real time decisions. I have used both Olympic and Thermo-Fisher guns.

@mineoperator 10 месяцев назад

Hi Jon, I appreciate your comment. This sounds like a method we should consider incorporating. Interesting idea to address nugget affect 🤔. I have to try that. Our XRF is the Delta 6550 50kv unit with tantalum anode. We have 4 modes but use soils and precious metals modes the most.We may get our hands on a new Vanta for a short period of time to try it out. We haven't tried Thermo-Fisher. Any feedback on Thermo-Fisher?

@jonsdigs1 10 месяцев назад

@@mineoperator XRF works great for silver but sucks for gold. However silver and gold values usually correlate. I loved the TF Niton but the price was higher.

I forgot to mention i found some old working in southern cali with Huge Old cyanide waste piles. Of course, i had sampled them and to my surprise, there was quite a bit of fine gold contained in the samples. your cyanide dump does have some good value which again i find surprising considering the effectiveness of the leching process....

@f.k.burnham8491 10 месяцев назад

I am curious to know if you are going to sample the bottoms of the tailing piles, as we all know that heavy materials will work their way down to the bottom. Also, is there any hazard in working through the cyanide processed tailings, mainly cyanide poisoning from poorly cleaned materials? Thanks.

@mineoperator 10 месяцев назад

Great questions. We do plan on going back to survey the both the dump and cyanide tailings. We are working on a "Notice of Intent" with the BLM in order to use an excavator on the property. Otherwise, we will trench the best we can by hand on a day much cooler than the 110F day we had. I have a cyanide testing kit that I'll use throughout the sample. We will wear respirators taking those samples. The cyanide is usually destroyed by UV over the many decades. However, at depth, anything is possible.

@krakhedd 10 месяцев назад

How much money could be made by running all the tailings through a plant to crush it down and extract whatever's left in it? Or maybe the better question would be: how much time and money would somebody need to invest, to be able to crush it all down and extract whatever value remains in it?

@mineoperator 10 месяцев назад

Hi Paul, we need to perform a survey to confirm these numbers, but using Google Earth, early estimates are 10,000+ tons on the top dump and 2,000+ tons of tailings. Using the low figures we came up with in our sampling program, it's possible that there's $1.5mm in gold and silver on the surface. Our plant currently can process 6-8 tons per day. Adding a 2tph table, new sandscrew, increase the pond size, and a piece of heavy equipment, we could process 2tph or 14-16 ton per day. We'd have to haul it to the mill, so include hauling charges. Shooting from the hip I'd say $100,000-$150,000 in capital could get the job done. If we processed 220 tons per month with upgrades to the plant, 4.5 years. These are all rough, early numbers. There maybe ways to engineer it to process it closer or onsite. It's worth the research. I did not include operating costs over the 4.5 years. Early estimates. If the grade of gold in the tailings goes up, there could be $2-$2.5mm on the surface.

@krakhedd 10 месяцев назад

@@mineoperator is that just the two of you working? That sounds like a FT job for a few years, there wouldn't be any prospecting or time for much else. But $100k a man, tax free, for 4 years sounds like a good gig too

@mineoperator 10 месяцев назад

@krakhedd, depends if we can setup a mill close to this mine or we need to haul it a few hours to our current mill. Would probably be 4 full-time. We definitely need to count the costs closely to see if it's worth it.

@greedygringoprospecting6941 10 месяцев назад

@myadventure7069 10 месяцев назад

Can you recover that gold that is question.tests tels you there is a gold but can you recover that gold. From my experience gold is almost an every rock, but can you recover it? I not believe in any test results they are useless . You need look at recoverable gold . And methods hou to recover that gold or another metals

@mineoperator 10 месяцев назад

Thanks for your comment. I stated in the video 3 data points and that can include identifying if you can recover the precious metals with your current mill process. We didn't see any free-mill gold at this mine 😕. Further testing is in order.
