How Low Can They Go?19 Oct 2020 10:57
Hello Everybody, I was thinking about GGP saying their drill holes remain open at depth. Then I wondered how far they could drill down in WA. As far as I know, the deepest drilling hole into the Earth’s core is the Kola Superdeep Borehole. (There are other attempts, less deep – US, Japan, German) The Kola is 12.2 Km deep. The Russians ran out of money for drilling and have sealed it up. The Earth’s mantle, just under the crust, is 2,900 Kms deep. Then you get the Outer Core of 2,250 Km and the Inner Core of 1,220 Kms. The Inner Core is solid iron ore but the Outer Core is molten. Scientists have estimated the meeting point of Inner and Outer Core to be 6,000 degrees C (10,800 F) – the same temperature as the surface of the sun. Can you imagine that? A length of 2,250 Kms (1,398 miles) as molten iron ore lava (basically). Then on top of the Mantle, there’s our little land mass (Continental crust of 10-75 Kms) and the Ocean Crust of just 5-7 Kms.
Obviously GGP drills are only going down a fraction of that distance, but there’s still terrain, shear and stresses, and drill direction (straight vertical or angled decline) to be calculated, and the equipment designed to withstand those pressures. And all I have to do is buy shares and wait for the shiny stuff to come up. My part is all of this is a piece of cake.
