Machines like the Falcon MD20 can detect free mill gold in ore far smaller than a normal detector but it can only tell you if the rock in your hand has gold in it or not, it won't find the vein only tell U if it's good or not. The big mining companies often use a form of ground penetrating...

Zengeo I've little doubt that it will be decent value, just that it may not end up being the price range l had originally been expecting. Kind of the problem having someone that's used to working with high end stuff, they don't want to do things cheap, they want to put in the effort and money...

bjarvie Yeah l know where your coming from. He wants me to bring by a decent amount of rock to run through for testing later this month and while l have plenty of rock it's going to be a pain getting that much of it down to a reasonable size. I'll see how this project goes first before l start...

Still in development and not really going in the direction l was originally expecting. I had asked him to build me something similar to the K&M 14 inch crushers, but seems he doesn't like doing things by half so is building a lot more than l originally had in mind. He is currently waiting on...

In the right spot they(the fluid bed designs) sound like a great unit, but just keep in mind they need a lot of water flow(more than a regular sluice). I wouldn't mind adding one to my kit, but serious lack of water around here. The gold mat sluices are good, l use a couple of them, they like a...

Yep and while lm sure the Armstrong industries units are made well, they have been out of stock of their mini crusher for awhile now and it's a big step up to their larger units. When l say hammer mill ln talking about similar to what they use in their(Armstrong) impact mills, not chains, but...

Yeah lm not after bids for a product that hasn't even been made yet, more just getting an idea of the price range people are comfortable with or what features they would want, as that would probably help him decide how much work and types of materials to use. The main difference with the...

By small l mean something on pneumatic tires that you could push around or put on the back of a ute, instead of the massive stuff he has helped build for mines. Yeah lm not entirely sure of the market myself. I have a dolly pot and l have a small angle grinder mounted crusher, but wanted...

Not for sale, just wanted to know how much of a market there was for them. I currently have one of my uncle's building me a 14" petrol driven hammer mill. He's got a mountain of experience building all sorts of high end gear, but this is his first small Rock crusher. I asked him to build it...

I brushed one off that was crawling over my toes yesterday. Was digging a hole near the house and had thought it was just an ant. They aren't considered dangerous though, unless your allergic or have other issues going on. They do hurt though and not not like a little bee sting, but seriously...

Different types of honey(dependant on the flower) have different properties, but most of the stuff you buy in a supermarket is heat treated so looses most of the antibacterial properties. Even time if year it's collected can make a big difference, but yes it can be very effective. An even...

It's sad that these supposed threatened or endangered species create such a nightmare for farmers and miners. Most are not Keystone species by any stretch, just a subspecies or grass or flower or tree. The thing that really bothered me on my land was that it was so hard to even find out what...

I use a cheap microscope from eBay that plugs into my phone for gold and an endoscope for checking car cylinders, both work well and are great to play around with. The microscope makes even the tiniest pickers look impressive.

Dredging seems a bit like a forest fire, if done right it's healthy for the system, if done wrong it can be devastating. Unfortunately most people just see fire and freak out without realising how the natural system works.

I get where your coming from, selling to smelt is of course going to drop the price, but smaller lots like this are probably best being sold on eBay or similar. Any nuggets over a gram generally gain some premium over spot on eBay and of course the bigger the nuggets the bigger the premium. It's...

Are you quoting spot gold price there or what the mint will pay? Cause nuggets generally retail at quite a premium over spot, especially Australias high purity nuggets. Looking at the current spot gold price if it was pure gold with no inclusions then spot price would be a little over $2400 aud...

Also worth noting that while creeks are generally waterways, gullys are not and often the only way to tell the difference is to check the applicable maps. What constitutes a waterway is often purely a bureaucratic mater with little regard for real world conditions.

Clearly worth more than spot gold price... Have a look on eBay to get an idea of approximate value. By all means please take into account vendor fees and stuff along with the risks involved by listing online, but yeah nuggets of that size shouldn't be getting sold at spot.

Sorry mate, l think the topic moved on to safety and regulation/over regulation/nanny state, because that's what seems to have led to the closure of this operation. Anyone have any suggestions on how we can help this tour operator or improve the situation at all? The whole area had a gold rush...

I had to do a traffic control course as part of another job years back, lve never done it in the field but l learnt a lot about the regulations. My biggest issue with road works is the way projects often drag on for many months when they should have been completed in a few days/weeks. Having...
