GeoHUG is an initiative that brings together the global geoscience community to connect, laugh, and share ideas, information & knowledge. Through our webinars, networking events, and open discussions, we create a vibrant space for learning and growth. An initiative by CoreSafe Core Solutions & Prospectors Supplies.

Being Chief Geologist from the country with the biggest landmass (and holding vast amounts of mineral resources) is a very impressive job. Probably one of the most underrated jobs on earth. Thank you for this interview.
Having lived through this scandal, I really enjoyed the backstory for a more behind the scenes look. What a story and well told! Thanks for sharing your experience!
I think I’m actually going to tattoo a skarn on my chest along with a few strikes actually give the tattoo artist pieces that I have found because I go outside and play and I listen to experts like this expert that is dedicated probably years of his life, studying middle of the night and to share this information with us, it’s such a blessing
Why do people virtue signal about lands, other never owned and/or lost in wars. Would you do this for the Christians or the Greeksand Armenians of Anatolia? Which was conquered around the same time. (Actually, the Armenians just lost their traditional homelands in rhe last couple of years, to the Turks. Who committed genocide against them But sssh! We don't talk about them. They are White.) The Turks and other conquerors, usually exterminated everyone. This just about crapping on White Europeans and making them feel guilty. The Europeans somehow did things differently than any other peoples. But then again, saying anything about non White people being both murderous and racist, is probably racist in your eyes. They above reproach, right?
Well done Ross. I have just done something similar for an epizonal gold antimony project. The Fe to Ca numbers are picking up the sulphide, ankerite, siderite and calcite zones. Combined with trace metals it is working on pXRF soils
Shadows of Nuna persist at depth! So the Mantle Transition zone provides water right? The LLSVP’s are they slab graveyards or remnants of Thea -earth collision? Oh, the Andean subduction zone post dates a lot of plate Pangea plate breakup and motion so there could well be interesting developments between micro plates and larger Argentinian blocks. Timing….I am looking for signs…just south of the el Indio Au province. Copper porphyries at the Miocene hinge? At a plate fold…in a translithopheric rhombic/transpression basin. I certainly agree with your approach. We are drilling a bit in no-man’s land.

I had no idea that the surface of the ocean mimics the topo of the sea floor, this is incredible. And certainly impressed with the difficulty of finding the vents, and all the technology involved in studying them, great talk, thank you, John and thank you, Geohug for hosting
I literally discovered this 7 years ago and was blocked by Mainstream Liars. Heartland Gold and Gemstones. Australia. But the biggest deposits are impact created Volcanic pops, during initial impacts. Facts.
A Great Talk is an understatement. Thank you from the bottom of my geophysical heart to you Larry and Jessica. I've worked on a number of skarns around the world, but I had to focus primarily on their geophysical responses, namely sulphides and magnetite. Now I have your interpretation criteria and even The Master Diagram. I feel like I have entered a higher Masonic level. It will improve my interp for skarns. K
A great talk Jen. I''ve been working on epithermals in AZ so this is opening my eyes to what I may have missed, particularly older mineral systems. Cheers.
Clear as mud, but I was able to extract some useful information with my very limited understanding. Thank you. As a self educated surface prospector this stuff really makes the mind work hard to gain the required understanding and apply it to my own prospecting area.
38:40 Wait what? No there aren’t. That is approximately the maximum estimated effusion rate of the enormous 1783 Laki eruption. Now, in the case of Iceland’s current Sundhnúksgigar eruption(s), it was the _inflow rate_ to the mid-crustal magma chamber, that was estimated at 7,400 cubic m/s. As for the effusion rate-the rate of lava actually exiting the edifice at the surface-the maximum effusion rate was measured during the spectacular first hours of the December 2023 eruption of this series, and the IMO only estimated it at “hundreds of cubic meters per second”, which was impressive for one of these modern “Reykjanes Fires”-type events, but in no way on par with the scale of something like Laki in 1783 or Eldgjá in 939 CE. Moreover, this was only a _maximum effusion rate_ . The average effusion rate is much, much smaller, down to single- or low double-digit cubic meters per second. If the Sii Ax eruption had long-lasting effusion rates of 1500 cubic m/s, that is impressive. Rather than separate flows, I think what is being observed is the fact that within single eruptions, flow lobes, channels, and lava tunnels can get choked off or blocked, such that no new lava is being transported to the lava front. At this point, a new lobe begins to advance, sometimes over the older lobe, or as a breakout emanating from further up the older lobe. This may occur several times in a single eruption. Alternatively, as we see in Iceland currently, multiple “eruptions” from the same magma source may occur just days after one another, with basically identical bulk compositions and even mostly identical petrological characters, though over the life of the eruption the crystal fraction is likely to increase, concomitant with a decrease in eruptive temperature and volatile gases, in a simple “Wadge-type/Type I” basaltic effusive eruption, modeled as the simple tapping of a pressurized magma source, whose effusion rate-initially high-decays exponentially. Though technically there are different “eruptions” caused by different feeder dikes breaching the surface, the lava exuded by them may be almost impossible to distinguish. But awesome talk generally. I crave any information about these super-understudied volcanoes that I can get, and the work of LeMoigne especially seems awesome…have to check that out. The NCVP is a very interesting volcanic province.
The success of such companies like imdex lies in the incompetence of the field and staff geologists especially of big corporations. They rather delegate the jobs than upskil themselves.
Global recently had a investor update and reported that everything is proceeding as planned. They expect to close debt financing with US and Canadian development banks at the end of Q2 (this quarter). We shall see.
I used a truScan a while back. It was pretty neat except that it seemed unable to understand that the read head is 3d, so it wouldn't raise up properly when the core had an elevation change, it would lift a bit late. I found that strange since it had an elevation map of the core from its first scan. What this lead to is damage to the head and it would push the core around and fail to scan it. Was doing this in ~2019 so hopefully that issue has been resolved by now, since it was just a software implementation thing and not a hardware issue.
HI we have been busy scanning core, hence the slow response (unlike our super fast core scanning platforms). Did you know, last year Minalyze and Veracio joined forces which means we have now combined our expertise and unique IP. One of the nice advantages that has come out of this is increased scanning flexibility in the TruScan, addressing exactly how fast and nimble we can continuously and consistently scan core.
Thank you Dave and Jessica. I am just back from Cambodia to my home in Lao PDR. 70% of our geophysics is with Chinese clients. They are less risk aversive and yes have Beijing setting their KPIs. When I started with Placer Pacific in 1985, North America was setting our KPIs and we were making discoveries and Mines. We are now making discoveries that are smaller in the most part, but the big discoveries will happen again because of the supply demands. I don't get caught up on which countries benefit. Empires come and go. But the climate temperature rise is nothing we can deny. Record highs here at the moment. A shame the Gross World Burning chart could not be up to 2024. A big increase in renewables since 2018. 劳动节快乐 - HAPPY LABOUR DAY. Keiran Logan/Logantek.
Awesome show! I'm older guy who had the pleasure of working with my dad running zinc and lead mines. We used pine oil I set up the first spectrophotometry lab. LoL 1972
Great presentation by Lynthener Takenaka. Thank you so much for such a kind presentation. I hope we explore Diomond. Special thanks to Dr Keast who has a great deal for the GEOHUG webinar.
