Hi guys, I came across this youtube footage that you may find interesting. You may recall the post I did a few weeks ago showing Martha Mine open pit wall collapse.
This footage shows a bit more of the surrounding country & you will notice in some shots looking out to the coast towards Waihi Beach which is where we stayed when we were up there for Mrs JW's 60th birthday. The actual footage is old "news" now. But interesting none the less. Enjoy.
Good luck out there
Above is a quote from Jasong, from another thread that hits the nail on the head. Somewhat a forbidden topic on OZ forums, which I guess says a lot about social media. This matter has been touched on by others when speaking about the "new age" coils on the Xs in other threads. While I`m a confirmed and dedicated Z user, I recognise because I`ve experienced the ability of these coils and how they have closed the gap( in the field on undisturbed gold), plus in some cases exceeded the Zs ability. Saying that I`ve also experienced more cases where the Z exceeds the Xs ability.
But it is interesting and really says it all about the dominance of ML, their only true competition to their latest serious gold detector is their model it replaced. This has been so for how many years? What are the other detector manufacturers doing? And why is it sort of "taboo" to post about this subject?
Hi there all, Last saturday was Mrs JW's 60th birthday. We had organised to go up north to make it a family reunion with our kids, grand kids & close long time friends. We booked a waterfront house at Waihi Beach that slept 10 & where the front yard merged with the ocean beach. Beautiful spot. Waihi Beach was a great central place for people to come to & was an area where I lived for most of my first marriage & where my kids grew up & went to school. Three of my boys still live & now work in the area & are no more than 10 k's from each other. The oldest two have a son each, so two grand sons for me. My fourth & youngest son is over in Brisbane, Australia. He was going to fly over but it turned out to interfere with a two week schooling block course for his electrical engineering apprenticeship that he his doing. Both Mrs JW's daughter, son & his partner & there daughter (Mrs JW's grand daughter) came & stayed with us along with a few close friends who traveled to be there for a long weekend.
On leaving a beautiful hot sunny Queenstown I landed in Auckland to rain. And it rained for three straight days. Mrs JW had flown up earlier than me to go even further north to stay a couple of nights with a close old friend of hers at a new place that she had bought. Mrs JW picked me up from the airport & we headed straight to the beach. Luckily the place we had rented had a games room so the rain didn't bother us too much. So it was socialising, drinking...opps...I mean celebrating, eating, playing pool & table tennis. It was a good time to be with family & close friends. We are making easter time an annual event to do the same thing. one of my sons told me that the Waihi Martha mine open pit had had a major collapse & was likely to end the open pit operations of the mine. They are also under ground mining....so not all is lost. You will recall this over view of the Martha Mine operation that I put up not long a go. The open pit is pretty much right in the center of the town.
On our drive back to Auckland we went through Waihi to check out the collapse.
This is a mock poppet head serving as a monument to what used to be several of these back in the old deep underground mine working days.
Parked underneath it we head on up to the viewing platform, walking past another monument. The old Cornish Pump House that has actually been moved some distance from where it originally was over a deep shaft, that was collapsing, where it pumped out the water from the under ground workings.
So this is what greeted us at the lookout viewing platform. Just below that big tin shed top right of center you will see the haul road going diagonally to the left right through where the slip has taken it out. lt curls on around the open pit to where you cant see it passing directly below in the foreground & winds on around the back again & passes right through where the slip has buried it with a few pebbles. Note directly below & to the left of that tin shed, beneath the haul road, quartz veins in the pit wall. You use to be able to see the old mine drives in the pit wall as well & the old timbering supports & large chambers that they had stoped out.
Bit of video footage.
On getting back to Queenstown I was hanging out for a detect. Oh...the withdrawals. So I headed to the hills for a days detecting. It was damn hot & dry & I didnt last the whole day. Gave up by 3pm. It was a bit of a struggle hitting on some gold but I finally got a sweet little faint signal in my hot settings.
Down into the rotten schist bedrock & the signal was singing. Just knew it was going to be a sassy bit of gold.
And it was. .7 of a gram. YE HA
Ended up with three more little suckers for a total of four for just 1.31 grams. Still...better than the skunk.
Good luck out there

Over ten years ago I was pushing pretty hard on the idea that high power pulse induction detectors would eventually find use for more than just nugget detecting. Relic hunters in bad ground seemed a particularly obvious situation where PI detectors could pick up where the VLFs left off.
Daniel TN just made a great post over at Dankowski’s about the shift from VLF to PI, and how the PI use progressed up the power ladder from Garrett Infinium to White’s TDI to Minelab GPX.
I ended up calling this Steve’s Law Of Target Depletion. The basic premise is that if high value targets exist, people will start with discriminating VLF detectors and dig the easy targets. However, knowing good finds remain, over time more trash is dug and more powerful detectors used. As long as any chance of a good find remains, this progression will ultimately deplete a good location of all targets, good and bad.
Prospectors see this all the time. A location will start with trash and gold. VLFs cherry pick out the easy stuff. Then the “dig it all” troops go to work. Sooner or later you get to where just finding a target, any target, gets to be a challenge. Yet as long as a single target remains, good finds still might happen. If nothing else the trash can hide good targets lurking below, and so even trash remaining can be a good sign. You can never call a place detected out until no targets at all remain in the ground that can be found. And even then, a newer, more powerful detector may make the place come to life again, at least for a time.
Watching his videos it sometimes looks fairly impressive. But his testing methods are limited to some weird coil inside a home lab and seem dubious. The EMI filter is tested outside and seems pretty effective, but many of the reviews I've found online are completely counter to what he shows in the video and generally seem to be ineffective.
I've never run into anyone in the US running one of his GPX mods but he told me he's done quite a few for guys here in the states. Is it totally bogus? Anyone out there actually paid for the mods and put some field time in with it? Anyone bought one of those EMI filters?
