Just to spread the risk I have decided to sink a shaft on the claim where people are already mining while I still decide on the way forward on my own land. The guys are now 4 meters deep and have now reached competed rock which we are now drilling using a jack hammer and explosives. We will give the owner of the property 25% of whatever we get. Its a sort of tribute arrangement.

We are sinking a vertical shaft targeting the known proven reef 40m below. In a month's time we should get there. This project is just to diversify the risk. It is actually less risky because it is on the brownfield where people are already mining. Most of the miners abandon their shafts because of water  at around 70m. We are hopping to go beyond these levels as we will be having the proper pumping systems that they are generally reluctant to invest in.

We will collar the shaft soon enough

Below are the pictures

I am thinking of sinking 2 shafts now, maybe 30 to 35m deep then digging a tunnel to connect them. That way will I not intercept the reef? How feasible is that? The cost of digging the 2 shafts is very low here.

Meanwhile on the other shaft the guys are now 10.5 meters deep. Progress is slow but I am hoping the pace will quicken this week as I now have 10 guys digging. The rock is changing from weathered granitoid to more competent granite and soon we should be in bluestone which is quite hard.

Scares the hell out of me.Hard hats will not help.Got a problem with digging my own grave.Just saying luck Mcbain.
I started out with nothing Istill have most of it.

13.7m  now

And  i  visited  a  nearby  mining  site  left  by  the 'Germans' way  back. I  dont  if  they  were  trully  Germans  but  the  locals  say so.  They  are  pumping out  water  so  they   can  mine

I am attaching photos of the progress so far. We had intended to drive into the reef at 35m and then tunnel along it but the grades there were too low and we decided to continue sinking the shaft down. Water is coming out of the reef so we dug a sump at 35 m in the drive so we pump water from it while we sink downwards.


The shaft is now 38m deep. Our target is 55 to 66m as that is the depth where the guys in the area have been getting high-grade ore.

There is a lot of water but we are pumping it out well using a diaphragm pump.

So currently we are 38m down-shaft and progressing slowly.

If you had an acid solution with say had cadmium and silver dissolved and you only wanted to save the silver from the list below you can see that cadmium is well above copper in the list.

With the addition of a piece of solid copper only silver would precipitate from the solution leaving cadmium along wih any of the other trace elements in red behind.

Using a piece of copper is a cheap way to confirm the presence of a precious metal.

There was a mining company that discovered they were losing values in the discharge water from he tailings pond into a stream. They put used tin cans into the stream, the cans salvaged the post precious metals. The company once a month would collect the cans which would then be refined.

IMO you could be tossing out the baby with the bath water.



Magnesium   Mg   displaces H2 gas from steam and acids and forms hydroxides
Aluminum   Al
Zinc   Zn
Chromium   Cr
Iron   Fe   displaces H2 gas from acids only and forms hydroxides
Cadmium   Cd
Cobalt   Co
Nickel   Ni
Tin   Sn
Lead   Pb
Hydrogen gas   H2   included for comparison
Antimony   Sb   combines with O2 to form oxides and cannot displace H2
Arsenic   As
Bismuth   Bi

Copper   Cu
Mercury   Hg   found free in nature, oxides decompose with heating
Silver   Ag
Palladium   Pd
Platinum   Pt
Gold   Au

The water is coming from the exposed reef in the tunnel at 35m not from our shaft. So we are not interested in sampling the reef at 35m. Our interest is in the same reef further down at about 55m or so. Now we are just 10m away so in a few days we will drive into the reef and see what it holds for us

 <-wave-> Thanks Tinman II. That's a really simple way to test water and maybe recover some metal with out a lot of work  <-party->  This is where I will fetch a pail of water  <-laugh-> <-laugh->
just keep digging

 <-wave-> thanks again for all your help. Nice to read posts and learn so much. ph of water is 7.1.The orange mud that settles out of the water is averaging .16 oz. per ton AU

Hey Gill,Not all of us think you are nuts.You have just gone beyond the norm.Most of us have no idea what you are talking about.We are simple minded diggers.Like me.Some understand and really respect your knowledge..It helps them a lot.Beam me up scotty. ;D.Luck Mcbain.

At 35m we drove into the reef, sampled it and thought it was not rich enough and continued digging downwards. We had driven horizontally 3m. We then drove a further meter or so to build a sump basin as when we got into the reef water started flowing out. So the guys are digging vertically going down now. Reef at 35m was 3 meters from our shaft. The blast for our sump exposed the reef further and I decided to take it for fire assay.

The results were 143.2 grams per ton which was quite surprising considering when we had initially gotten into it, we thought it was useless.

We have since decided to continue with our downward push then we will drive into the reef again at 50m or so. Our confidence levels are now so high that we are literally shaking with excitement. we know the reef is there and we know chances are higher it will have good grades of gold.

We had expected to intercept the vein at 40m but the vertical shaft has not done so. It looks like we are now parallel to it as it is probably now vertically steeping.

The gold is in quartz veins, I would say in bands with sulphide and sometimes along the margins. There is a lot of pyrite in the quartz also. The quartz veins are hosted in very hard bluestone. We have breaking our drill steels and bits like every time.
