2. Regarding the eagerly anticipated conglomerate test pit assays, this news release went on to state, very simply: Test work is on-going on the conglomerate samples, with analytical procedure focused on optimal recovery of the fine gold. Free mill gold also runs with sulfides. The Kairos exploration demonstrated that any indication of gold in conglomerate sampling was anomalous and worthy of follow up work, no matter what the tenor of the gold grades. The combination of nearby basalt conglomerate units, alongside considerable quartz veining, could be a very promising sign for EYM’s new project. These new areas has yielded a total of 135 gold nuggets and with patch #1 have a total of 391 nuggets with a combined weight of 19.3 ounces (600.3g). The samples were extracted with an electric rock breaker and weighed 49.5 and 55.5 kg respectively. Sedimentary rocks at Palo Duro Canyon State park, Amarillo,TX are from the Permian and Triassic periods. Disclaimer General Disclaimer . 2020 | 11:28. We crush and pan gold bearing rock and heavily mineralized rock. The were sent to samples the Saskatchewan Research Council where they werecrushed to less than 2 mm and homogenized. an electric rock breaker and weighed 49.5 and 55.5 kg respectively. ROCK-HOSTED GOLD DEPOSITS The deposit-scale geologic characteristics—such as host-structure, host-rock, alteration, and ore minerals for both Nevada and Chinese sedimentary rock-hosted gold deposits—are well documented in the geologic literature (see Christensen, 1993; Liu, D.S. and others, 1994; Wang, Y.G. A recent 985 tonne bulk sample of exposed pyritic conglomerate returned a head grade of 4.2 g/t gold in a pilot plant program. Gold-bearing Sedimentary Rocks in Northwest , Wyoming­ A Preliminary Report By J. C. Antweiler and J. D. Love ABSTRACT Thick sequences of gold-bearing quartzite conglomerate occur in latest Cretaceous and Tertiary formations and in Quaternary gravels derived from them in northwest Wyoming. However, the odds are lower, as others have stated. Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal. Conglomerate gold refers to nuggets hosted in rock containing rounded […] Geologists are now focused on understanding how the gold formed to determine whether or not the region, best known for its iron ore, could be further developed for gold. Evidence for this comes from the facts that the gold is older than the host rock, the gold is found almost exclusively in the conglomerates and some gold shows a flattened, circular appearance, indicative of water transport. by KevinInColorado | Updated November 11, 2020. When conglomerate gold nuggets were discovered in the Pilbara in 2017, it sparked an old time gold rush. Researchers Graham Pearson (left) and Jesse Reimink examine conglomerate rocks in Nunavut. Conglomerate gold in the Pilbara is typically nuggety. The gold and platinum are characterized as “coarse” when compared to the fine gold in the conglomerate. The Vancouver-based company says the Skyfall prospect is situated about 2km south-west of the existing 900,000-ounce … Flickr is almost certainly the best online photo management and sharing application in the world. A conglomerate is sedimentary rock made up of chunks of various materials which in this case includes deposits of gold. Castlerock Conglomerate gold in metro-Denver. TIM TREADGOLD reports Gold is found in the conglomerate strata of the younger members of the Supergroup, locally referred to as banket. They often host resources such as coal, petrol, natural gas, and uranium. Ex. and others, 1994; Bagby and Berger, 1985; Kuehn and Rose, 1995; Arehart, 1996). Castle (ASX:CDT) is looking at selling its Ghana gold assets to focus on its “Witwatersrand-style” conglomerate-hosted gold mineralisation in the Pilbara. Rock is dark grey-green to brown hornfelsed sandy conglomerate. Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits. Some placers are re-concentrated from older placers, but at least some time in the past, these came from primary deposits. This presentation contains summary information about Marindi Metals Ltd (Marindi) and is current as 13 March 2018. Pilbara Conglomerate Gold Conference Exploration Underway at Bellary Dome March 2018 ASX: MZN 1 For personal use only. As the pipe eroded, the diamonds washed into the streams and rivers which later dried up and the material "cemented" together to form a conglomerate of sand, pebbles, stones, gold and diamonds which eventually hardened into rock. erosion and deposition. But just as fast as investors piled into the story, they fled when they realised just how hard it was to turn these coarse nuggets into dollar bills. The company’s Rocklea Dome project has about 10km of strike of the Hardey Formation within its boundaries and a substantial area of the same rock sequence is interpreted as being under cover. Similar gold conglomerate deposits have also been found in South Africa. Note that nuggets are rounded, clear evidence they are detrital in origin. Activity around the Pilbara conglomerate gold story is again hotting up and it is far from done, according to the head of Castle Minerals. These conglomerates are mined, crushed, and processed as ores. Results from conglomerate-hosted gold at the similarly challenging Pardo deposit in Ontario highlight the variability in sample grade in this style of mineralisation. TSX-V-listed aspiring Pilbara gold producer, Novo Resources, has unearthed a new gold-bearing conglomerate reef discovery at its developing Beatons Creek gold project adjacent to Nullagine in the East Pilbara following a mapping and surface rock chip sampling program. A 5 kg split was taken with a rotary splitter and analyzedfor gold by fire assay (1 assay-ton) anda 3 kg sub split was analyzed with metall- ic screen fire assay. 300 million years old Diamantina, Minas Gerais, Brazil Millions of years ago there was a diamondiferous kimberlitic pipe somewhere in Brazil. The information in this presentation is of general background and does not purport to be complete. Golden Eagle is now set to become a production hub for Novo’s conglomerate gold projects in the southern Pilbara, with the first cab off the rank likely to be the 11 million tonnes of gold bearing ores at Beatons Creek. Pactons Agreement with Calidus allows it to explore and exploit any conglomerate or transported gold deposits in the sedimentary rocks overlying the basement rocks in the Calidus holdings, which are scattered from the town of Marble Bar to the Nulllalgine-Beaton Creek area. A gravel-grade clastic-sedimentary-rock. The framework grains in this specimen are not in contact with each other, seemingly “floating” in matrix (Figure 4-A). Analysis of the 15 kilograms of samples they collected revealed three small diamonds within the rocks—an unexpected find that sheds light on what geological conditions were like on Earth three billion years ago. The Beatons Creek deposits boast an impressive resource of over 900,000 ounces of gold grading around 2.4 grams per tonne gold. Researchers Graham Pearson (left) and Jesse Reimink examine conglomerate rocks in Nunavut. Jul 29, 2019 - Finding gold in oxidized conglomerate rocks! I've found gold in conglomerate/cemented rock before, and there are deposits of gold in sedimentary rock as well. “Conglomerate gold” in the Pilbara became all the rage back in 2017. A 5 kg split was taken with a rotary splitter and analyzed for gold by fire assay (1 assay-ton) and a 3 kg sub-split was analyzed with metallic screen fire assay. Over 40 000 tonnes (44 000 short tons) have been mined from these rocks since this precious metal was first discovered here in 1886. The abundance of this gold is without a natural equal anywhere else in the world. They indicate a shallow sea withdrawing from the area, large phytosaurus fossils were also found. gold source rocks and found basal Bellary Formation conglomerates at each location, including the identification of an entirely new area, named “Block 3”, in the north of the tenement. In rare instances, conglomerate can be a "fossil placer deposit" containing gold, diamonds, or other valuable minerals. Nearly all placer gold, both coarse and fine, originates from the erosion of primary hard rock gold deposits. Multiple outcrops of gold-bearing conglomerate have recently been identified at Comet Well and Purdy’s Reward. Gold is high purity, 96-98%, setting it apart from that from basement-hosted lode gold deposits which commonly displays purities of 70-95%. October. So, speculation on how the Western Australian gold formed, and what this means for further prospecting, fuelled a modern-day gold-rush. A coarse-grained clastic sedimentary rock, composed of rounded to subangular fragments larger than 2 mm in diameter (granules, pebbles, cobbles, boulders) set in a fine-grained matrix of sand or silt, and commonly cemented by calcium carbonate, iron oxide, silica, or hardened clay; the consolidated equivalent of gravel. To be conglomerate, a rock must have at least 30% of its volume consisting of clasts larger than 2 mm, as this specimen does. conglomerate gold expert George Merhi, we have been able to discover an exceptional new nugget patch located some 2.5km south of, and within the same stratigraphic horizon, as the nugget patch announced just two months ago. Conglomerate gold refers to nuggets hosted in rock containing rounded grey quartz pebbles and other minerals. The samples were sent to the Saskatchewan Research Council where they were crushed to less than 2 mm and homogenized. America/Tegucigalpa. Mr Ronk mapped the Block 3 area in detail, identifying a conglomerate sequence beneath the overlying Mt Roe Basalt. (Photo: Supplied) 06.
