  1. Yes in the video the rock he was digging into was a conglomerate. True Iron Stone is black as black can be however I've found more than a few bits it it. What can be questioned is what you, or anyone, is kicking aside. What the video shows is what I would call latterite conglomerates~ a mix of iron and other materials~ that leads to pocket nuggets. Good stuff. Something I look for. That was part and parcel to my challenge in the last two years on "hot rocks". For me, having used a PI and VLF, looking for gold there were a lot of rocks that just got kicked aside. Surface stuff. And believe it or not there is a fair amount of surface stuff your going to kick with the Zed or any detector. In conditions like the video, and SDC on hot ground or even the Zed or a 5000, its not unusual and face it... how many carry a hammer ?? He has sharp signals. Something I outlined. I would not pass them up and the dolly pot would sing ;)
  2. Jasong I know what you mean. There are a lot of variations on kimberlite and not much in the way of what to look for locally anywhere. Most I've been able to ever figure out on my own is to look for garnets and blueish materials in area's that have volcanic activity. Other than that just checking the old gold pan, where there is water, and hoping for something interesting to show up in the cons.... snagged a fair amount of other stones but not the diamond yet. One of bucket list places to go is where they have been found before, Crater of Diamonds, however thats a trip I keep putting off for longer walk abouts ;) As Fred thinks so do I in that there may be a fair few in the tailings... but man thats alot of hard work. Grading is the way to go and rocks the size of a thumb are fairly rare outside of the mines. But who knows ;) Fred I'm looking more at opal and sapphire down under :) As my good friend and his wife do that a fair bit when they are away from the gold fields. Last year they were in opal, this year gold, next year sapphire in the north east. I did gold last year and kind of kick myself for not going over and doing the opal with them first.... depends on my funds. Your welcome when ever ya know :) This year is gold again and I may make it.... working like a wood chuck to do it though.
  3. In 2015 my partner and I armed with the then new Zed held a test on hot rocks. Of ten samples found 3 contained gold for me and of 8 he found, and allowed me to dolly *he really does not like the dolly pot :)* 2 had gold in them (he had a bunch more but wouldn't let old dolly bang'm). None of the rocks showed any gold from the outside~ ones that did didn't qualify and went into our collections~ though I did dolly a couple just to set his teeth on edge. Hehh! We both looked at the character of the hot rocks, iron stone/ conglomerate/ quartz, and the response to the detector, sharp signals/ broad and small ticks that just would not balance out, and concluded that it was worth while to pick them up. 2016 I did the experiment again with the criteria from 2015 : sharp signals and ticks, conglomerate and quartz or iron stone with quartz indicators : of 10 picked up 6 had gold. Not great masses of gold though. Each rock was only about fist size and yield was a gram or less but it was all flat and leafy. Total weight in 2016 was 2 grams and 2015 3 grams. Not sure how this experiment would play out in the USA as the material is different then that of Australia but its a fun experiment and I have about a half dozen more hot rocks I did not dolly in my collection I might check out one day.
  4. Would a stone as large as a marble stick to a grease table? Never used one myself. Only piece of equipment I have ever seen used is a shaking jig, manual and mechanical, however those fella's were after topaz and corundum's. It was fun tagging along on that trip and there were a few shiny treats in the screens.
  5. Good find and fine company I say!
  6. A likely source for all those Unicorn shoes I find :) But I'll just have to say you found the heel of the joke. *grins*
  7. Might want to see what that hopper circuit costs first :) Impressive bit of tech, gotta wonder what the folks up in the great white north would have caught with it.... but they are not working alluvials like the angolans.
  8. Maybe not in North America but another honking big rock, 227 karats, dug up in Angola. Man I'm just panning the wrong rivers! http://www.mining.com/another-large-diamond-dug-lulo/
  9. Look. Really just look. Steve put up a very comprehensive set of tests for what to look for... honestly take the yin and the yang and look at it. No such machine exists. Not yet. The ZVT is the closest "new" tech yet however it does not address all complaints. Will not in my opinion but it does a darn good job in many facets. I love it, ZVT, and spoke for it prior to its release. ZVT is one of the most potent releases in detecting times in my opinion. All are variations on the wheel but I do not diss any variants just pulse that the basics are already there... just that some one, some where, some when will make the click that moves the basics to the next level.... personally I dread that... any swinging *d* can then move up the bar.... and really. Everyone thinks they have Gold buried in their back yards. Funny how few try to find it.
  10. Thanks for the video I actually learned a bit :) hehh. Gotta say though, breathe slowly, almost looked like hyperventilation a few times. Death Valley is one of my bucket list items not just for the gold.
  11. One in the same klunker the way I read it. To find is to be found however finding is what the operator does and to be found is what the detector does. Sorry just thinking on the topic and I get a simile in my head. How does one re-invent the wheel? What defines a truely new type of prospecting detector? The answer for me is that there is no real way to do so. All that can be done is tweek the basic design and look at the results. VLF, PI or ZVT and any combination of these are all just tweeks on the basic design. One can talk about accessories all day long but in the end the base unit is just the tweek of the base design. A thought would be to make a machine with true imaging and composition read out but then would that be a new metal detector? I'm just playing with thoughts however.
  12. Doing all right Fred :) Working hard at hardly working and its not working out ;) Thanks for the cut view Deft Now you have bookends Hahh! A handsome piece of pegmatite. Coloration is very nice and it does not look like it'd take much polishing to impress the miss'us.
  13. I to would be interested in what the interior looks like if you get it cut. Though the rock pictured is quite dirty I appears to be more of a pegmatite that a quartzite. I've often had pegmatites sound off on a detector usually with the negative tones. That was a while back, pre-VDI, however there are some good bits to be found and rock gardens are a great way to train the eye. *or satisfy the wife as it were :}*
  14. Nice one Steve :) I do hope the person who gets it keeps it original. My own specimens have all had to come from rock and mineral shows and are itty bitty but who knows maybe I'll pick up a chunk like that one day in my pan.
  15. I'll simply second Klunker and Steve as those are a couple of the dominate methods for prospecting. Idaho has a lot of fine gold and more than a good chance of nugget gold. I've panned around to the north of Boise and the Snake river and always found a bit but nothing detecting. Give it a sample pan like Klunker suggests and see if Steve's insight to the area shows any old timers or current miners have shown any appreciation for the region. Luck and heavy pans :)
