Read Replies (1) | Respond to how close to the surface is the albany graphite mine in ontario and how deep does the deposit reach The deposit is described as “near surface, underneath glacial till overburden and a thin veneer of Paleozoic sedimentary cover-rocks.” Zentek Ltd.+2Zentek Ltd.+2 Specifically the overburden of glacial till is on average ~ 44 m thick, and the Paleozoic cover rocks average ~ 3.8 m in thickness. BC Government CMS Content+2Geology Ontario+2 Another statement indicates: “the deposit has an average 45 m of overburden made up of glacial till … and a thin veneer of Paleozoic sedimentary cover-rocks.” Zentek Ltd.+1 Also, a drill result noted near surface mineralization: drill hole #3 “upon passing through the overburden/limestone, the hole immediately intersected graphitic breccia …” indicating the graphite body is relatively shallow beneath cover. Zentek Ltd. ? Conclusion: The mineralized pipes begin just beneath the overburden and cover rocks, so you’re talking tens of metres from surface (roughly ~30-50 m to bedrock + cover) before hitting mineralization. The deposit consists of two adjacent “pipes” or breccia-systems, spaced ~250 m apart. NationTalk+1 The East Pipe is about 600 m deep . NationTalk The West Pipe is about 500 m deep in one estimate. NationTalk+1 The Ontario Mineral Inventory summary states for the West Pipe: modelled to a depth of approximately 525 m below surface. Geology Ontario Also: both pipes are cut by “barren sills” (10-60 m thick) located approximately 200-300 m below topographic surface. Newswire+1 A 2015 article states the deposit (both pipes) is well exposed at surface and “continues at depth within the non-weathered sheared gneiss”. Sama Resources ? Conclusion: The deposit has been drilled to depths of ~500-600 m, and mineralization remains open at depth beyond that in places. The main mineralized pipes are modelled to about that depth. The mineralization lies quite close to surface , beneath only a moderate cover of glacial till (~30-50 m) and thin sedimentary rocks. The deposit extends to substantial depth , roughly 500-600 m below surface in the main pipes, with potential to go deeper.
