Hydrofluoric?  What concentration?

 

In the early 1980 we got many tons Hydrofluoric Acid for internal cleaning of mill scale on newly constructed 375 MW Brown Coal boiler. It was shipped via road in steel tanks it concentration was 35%. I can't remember what it was diluted to. It was continuously circulated in a closed vessel for a couple of days. Most people would expect it to eat through the steel tanks at 35% Conc. but that is the normal process.

The big problem with a Weak Hydrofluoric Acid is that it burns into the skin and attacks the bone with very little warning in pain till it very serious.Vapours into the lung is very serious.

Gerry I was in the area 2006, with a couple years experience up my sleeve I cracked 32 oz for the winter. You did quite good for your first trip. I had three Yanks in my van begging to buy some nice size nuggets (2 oz in total) at a 25% above spot price. They convinced me to sell as they wanted something to show that their trip paid.  By the way one Emu egg make enough for four hungry Men. 

JW I hope you had better luck than me with Grand Canyon. We stayed there for 3 Days but it was fogged in and plenty of snow, visibility was not good enough to see the bottom. Niagara Fall made up for it as  stopped for us (froze over) Our USA,  Canada and the South Pacific lasted 10 weeks and was the trip of a lifetime.

If our cruise in August goes OK we plan a cruise to KiwiLand for our 50th Wedding Anniversary in mid Feb. Don't worry we wont steal any of your NZ GOLD supply. but hope to see your two main Islands.

Any nugget over an oz close to the surface sound like junk to me and the larger they get the more they do. ?

What year was that (Kalgoorlie/Leonora) Gerry.

I think the times quoted are for when you are on the gold.

I only have the initial Spectra. V1 don't use it much now. My method was dig every thing except when the coil can not be swung without hitting targets. Your problem is gold ring vary in size,shape and gold content. This means there is a wide range of reading you will get. However pull tags and a lot of junk target were mass produced and have a uniform response get to know these and then decide if you dig or not. One bit of advice is to try to get a beep at the same volume by lifting the coil up a bit as I got more accurate signal doing this on my detector.

Guys, this one is def not a “cross cut”. It runs prob at least 250m + up the ridge. At the end of one of the diggings you could see quartz. Upon leaving due to it getting dark I noticed further up but to the right an adit. Ill go back there tomorrow. It’s somewhere i can take the dogs without threat of deep shafts as i was discovering earlier today.

The only trenches that I have came across that are that long are water races. Your description seems to fit that. 

"but i can be a persistent prick!" 

I know what you mean, I spent many weeks in Wederburn back in 1980  with no results except the experience I gained. I now have found several kilos of gold. I was known as the old Duracell Battery  "Bunny Ad. "          Bunny Ad.

Lacky has got it right. A lot of new prospector have not heard a gold signal and the advice I gave would help in this case. I saw the mine and also the trench looks like a crosscut to find the reef. If that the case that slope may be worth a detect.

I have been scanning 35 mm Slides and came across a guy now resting closer to the gold. He was a real gentle man.   He put a stop to my dredging when he let my wife wear his smaller 16 oz necklace. If I remember right that is a 30 plus oz in his hand. The third photo is my collection of coarse gold I dredged that year.

The pick tells me that the old timers worked the area. Was it surface/trench or reef. That should tell you how to work the spot yourself. Have a read of Egixe4 post a page or two back it sounds like Yackandanah is a close site worth having a look. If you know a place where a nugget was detected, put a 5 cent, 22 bullet and a air rifle pellet in the ground at lest 4" / 100mm deep. The size of your finds make me think your expectation might be a bit high.  Hope this help in your pursuit 

Phrunt there is a place for fast swinging the coil. That is when you are out looking for a spot in unproven land, or walking to or from a spot. It is amazing how quick (pun intended) I slow down when an easy nugget yells out to me.? but good coil control as far as height goes. 

There was an old bull and a young bull up on top of a hill and a herd of cow in the paddock below. The young one said lets run down and knock a few of them up. The old wise bull said let walk down and do the lot in. Phrunt it seems like you are the young bull. 

You might use it to see if your large target signal is steel/Iron. That is if you get a good response you wont have to wear out your pick. 

AussieDigs by the looks of that area (photos) you are in I would be trying some of that flatter ground on the top of those hills if there is any indication of old timers working. The nuggets have not been given the down hill assistant of running away and should be closer to the coil than gullies.  

I think the gold part was maybe staged for the film, but I will pass on saying it was. ?‍?  I have been digitising  some of my old 35 mm slides when I get the time I will post some photos of my hike (trek) to a gold mine in Papua New Guinea during the early 1970s .

The first film done in 1958 was more than great and as a "bush walker", kayaker and Gold Prospector I enjoyed the whole hour and a half watching it. ??? 

Madtuna  I avoided over 10 Gwardar on a 3 Km section of the "bubblegum track"( https://www.bibbulmuntrack.org.au/) in West Australia. An old mate of mine used to run Nambi Station but lost contact with Paul about 7 years ago which Station do you run.

In the Summer the plain old brown snake is the worst in Gippsland as they are more likely to be aggressive than a tiger snake.Some of the most poisonous are in WA but in the outback but the ground cover is less and they are shy and get out of the way. In the late 1970s I had 2 occasions of a Black Snake  and 1 occasion of a Tiger Snake in the water with me while Dredging for gold. The closest to being bitten was when I was bush walking and a Tiger hit my Scarpa Boot since then I all keep a good eye on the sunny side of the track. How far would I go for GOLD is more limited to Distance or Time not Wild life or Terrain.

If we get all that gold here and it costs say $50000 an oz to get it here, the successful miners want a profit of say $1000 an oz, and put it on the market at $51,000/oz minimum or keep it stored what will that do to the present gold price? Will it realistically do nothing, or would emotion, speculation, greed and all those other human traits that drive our markets cause the gold price to rise or fall?

Aside from that there`ll be some ingenuity applied to lighten that storage for sure.

I think we all know what happen when you have too many tulips.

Phoenix I saw a rusty bit of junk that someone threw away near a trench that was put in to stop soil erosion. As I was using the wife Whites 6000d I thought I would test it to see if her motion discrimination would cut out this "2 inch rusty nut". It gave a good signal so I picked it up to show the Wife how the Garret Deepseeker was better than the Whites discriminator large iron out. As soon as I got in in my hand I knew it was gold. It turn out to be 2 ounces when clean up. No gold showed up till it was cleaned and the gold was porous in character. I showed at least a dozen prospector and they all said it was junk till I dropped it in their hand. Someone was unlucky but I was over the moon.

Youse guys should check that HOTROCK...it could be a meteorite. Of course you can't keep it...it would belong to the Crown.

Strick, almost everything in or under the caprock is golden...almost...

It is very exciting when you get a deep signal and it is under the caprock...the breathing gets short and the BP rises...then the work starts.

good luck guys

Fred I got a good signal under cap rock after getting down about three feet it open up to goanna  hole. All I got for my effort was a dingo trap. I don't know if the trap caught the goanna or whether he dragged the traps catch back in his den. Next time I will look for any burrows, the entrance was 3 meter away.   

I know that the 1850's was the best time for gold for the small time prospector. I would like to go back to 2050 instead, then I would know that I made it past 110 years of age.

What I did was get the data down load form each state and sort out the information for the locations and gold yields, dates etc with a GIS program and Excel. Now they have good map software, when I did mine this was not the case, with  the use of a GIS program I could use any map I wished to including right down to shire, google earth and district  maps. That was a excellent demo you posted mn90403 ?
