@Newton "The total thickness of the mineralized structure, a potential thrust fault remobilizing mineralization, is not yet known since it is at the base of cliff with scree covering the outcrop immediately below." epic #geology. What is basis for these claims about structure @robmcleod? Is the area 'brownfield' and what kind of past work has been done to support your description of mineralization? Blows my mind that you can call "stacked min." from trenching -- you must have more info on situation somehow? Keen to hear more if possible about how this description of mineralization.

@Newton Hitting all the familiar buttons for me here with #nr $idm. The whole "similar age as something 50+km away" thing hints at single supposed mineralization event that happened across #goldentriangle. And the potential for lost valley to give porphyry type structure to match high grade veinlets is also familiar. To get both on same project is big deal. Reminds me of $sea talk of their porphyry that is flanked by $pvg #vok and #iksut project on other side. Seems like we are writing a new chapter in #geology of the world here. Big deal?

@Newton $dna release says "This study demonstrates that as the drilling and sampling density is increased, in the portion of the V-75 vein examined, the grade and contained ounces also increase." OK, sounds good! Curious if that is normal #geology and how representative that may be as only for one hole so far?

@newstracker The Oldest Known rock on Planet Earth; The Acasta Gneiss is a tonalite gneiss in the Slave craton in Northwest Territories, Canada. The rock body is exposed on an island about 300 kilometres north of Yellowknife. The rock of the outcrop was metamorphosed 3.58 to 4.031 billion years ago and is the oldest known intact crustal fragment on Earth. #Geology #Canada http://www.geologyin.com/2015/12/the-oldest-known-rock-on-planet-earth.html#y1QQ1HVyZU4WlQ9S.99

@Newton $prg property next to goldquest $gqc looks nice on a map! Big fault (?) with both companies straddling it. I wonder if things are different on one side or the other. Surface samples good and some IP results working well with a hole, but I'm curious about #geology there $prg. IP stuff looking good as stepout acorss a kilometer. OK. You made me more comfortable!

@Newton That $mrl #aquisition in south eastern BC reminds me of of similar acq's by juniors in #goldentriangle. Seems most management talk about it as a property that will allow them to do work year-round, but I wonder if one of them won't have a big surprise out of these backup plays... any broad comments on #geology in southern BC?

@Newton Good comments by #Haywood analyst picking up on the #Eutompi deposit $KNT. Lies between Irumafimpa and Kora, "in the heart of the mountain". Deposit known at surface, but untested at depth. Becoming accessible as company builds out underground workings at Irumafimpa and moves towards Kora... Sweet #geology there imo. @newton/k92-mining-fast-track-production-with-massive-exploration-potential-clarus

@newstracker Wastewater from a mine doesn’t sound like a cozy habitat, but for untold numbers of microorganisms, it’s home sweet home. A new research project led by Professor Lesley Warren (CivE) will examine how these microbes make their living by studying their genes — an insight that could help further reduce the environmental footprint of the mining industry. http://news.engineering.utoronto.ca/ancient-microbes-offer-insight-better-mining-wastewater-strategies/ #mining

@newstracker The Anthropocene Epoch – a new geological era in which humans are the dominant force for change – is real and started sometime around 1950. This is the conclusion reached by the Anthropocene Working Group in August this year. The group will spend the next three years finding a suitable geological marker of this transition. But many scholars disagree because marking the date of 1950 is arbitrary and ignores the ongoing ways humans have changed the earth over history. http://phys.org/news/2016-12-scientists-dont-anthropocene-theyre-wrong.html #geology

@newstracker Scientists say they have a clue that may enable them to find traces of the asteroid that wiped out the dinosaurs in the very crater it made on impact. This pointer takes the form of a nickel signature in the rocks of the crater that is now buried under ocean sediments in the Gulf of Mexico. http://www.bbc.com/news/science-environment-38299804 #nickel #geology

news_bot U of T researchers find world’s oldest water in Timmins mine http://www.cantechletter.com/2016/12/u-t-researchers-find-worlds-oldest-water-timmins-mine/ #water #geology In results recently presented at the American Geophysical Union Fall Meeting in San Francisco, researchers described how the new find is at least 500 million years older than a previous discovery from the same mine, and that contrary to the presumption that water at that depth must be contained in rock formations, this water was freely flowing.

@Newton Thanks @MiningCatalyst. Would be happy to get into it a little further with you here. My sense is that these are first holes in new structure that is highly prospective based on rocks found at surface. First question was simply whether there was something underground there that might host gold. Looks like they found that. Next questions get into where exactly gold may be in underground structure. Not a geologist, but this is one that makes me want to do a #deepdive on #geology to understand what they think is happening there and what success/failure looks like at each stage...

@newstracker Scientists say they have identified a remarkable new feature in Earth’s molten outer core. They describe it as a kind of "jet stream" - a fast-flowing river of liquid iron that is surging westwards under Alaska and Siberia. http://www.bbc.com/news/science-environment-38372342 #geology #geophysics

@newstracker Researchers studied large gem diamonds by examining ‘offcuts,’ the pieces left over after the gem’s facets are cut. The researchers determined that these diamonds sometimes have tiny metallic grains trapped inside them. In addition to the metallic inclusions, some of these exceptional diamonds contain mineral inclusions that show the diamonds formed at extreme depths, This is much deeper than most other gem diamonds. http://www.sci-news.com/geology/diamonds-metallic-liquid-earths-mantle-04459.html? #geology

@newstracker Hot 'new' material found to exist in nature. One of the hottest new materials is a class of porous solids known as metal-organic frameworks, or MOFs. These human-made materials were introduced in the 1990s, and researchers around the world are working on ways to use them as molecular sponges for applications such as hydrogen storage, carbon sequestration, or photovoltaics. http://www.geologyin.com/2016/08/hot-new-material-found-to-exist-in.html#8BXG98eblcyiEjcb.99 #geology

@nlepan It's official: This 2.27 kg opal is the Largest black opal in the world. The opal was found in the Grawin Field of Australia. It was polished but with the intent to keep it as close to its natural state as possible.

@nicholaslepan Modeling Magma to find #copper. About 70% of the copper comes from deposits formed several million years ago. Despite similar ore forming processes, the size of these deposits can vary orders of magnitude from one place to another, the main reason of which has remained unclear. http://www.geologyin.com/2017/01/modeling-magma-to-find-copper.html #geology

@MiningBookGuy Just noticed @nicholaslepan posted the following while I was listening to it: The Northern Miner podcast – episode 43: Gold majors and a geologist’s guide to investing. http://www.northernminer.com/news/northern-miner-podcast-episode-43-gold-majors-geologists-guide-investing/1003782572/ This is absolutely worth tagging and commenting on! I highly, highly recommend paying special attention from 9 minutes 30 seconds to 20 minutes in. This ~10 minute section is #GeologyCorner from #LesleyStokes. This is super valuable #geology talk for #speculators / #investors. There are 6 specific points--I didn't think of many of these until listening here. Excellent for #newbies and more advanced people as well. Will tag #BestOfCEO -- it's that good! Also a shout-out to $IVN at the end of this segment as one that Lesley says is a stand-out in this regard. #NorthernMiner #Geology #Geologists #GeologyCorner #LesleyStokes #exploration #DrillPlays #mbgtrends #newbies

@nicholaslepan Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids. A group of scientists based mostly at Arizona State University now show that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond. #diamonds #geology http://www.geologyin.com/2014/12/asteroid-impacts-on-earth-make.html
