3-D Seismic Goes Deep/Proven Tech29 Dec 2018 22:06
For those wondering if/why our company is pursuing the 3-D technology across the entire concession in Egypt
“We used the 3-D seismic before, we used it at Long back in 2007 and that was key in some of the understanding of the geology towards Macleay and Moran, and with AngloGold Ashanti (IGO’s joint-venture partner) we have used it at Tropicana, so we have internal success stories we’re aware of there. We’re also aware of some of the external success stories else-where in the industry, like the work Northern Star has done at Jundee.”
That work included identifying “reflectors” at Zodiac, a new gold discovery 800m east of the Jundee mine near Wiluna where Northern Star sunk the deepest drill hole in Australian mining exploration history earlier this year. “In order to explore the vast areas of the earth that are undercover, you need the technology that can image under that cover and seismic is the best at the moment,” Mr Dwyer said.
“We did the 3-D seismic survey over Jundee for Northern Star and the process to get there is a good 18 months to two years to do the proper science,” Mr Dwyer said.
“The proof is in the pudding for Northern Star in that they’ve got enough information over a cubic kilometre volume of rock that they can drill to 3km depth at that rock.”
HiSeis’ model received a vote of confidence yesterday, with Ausdrill announcing it had taken a majority stake in the business...
HiSeis, a 3-D surveying company spun out of research by Curtin University, has been contracted by diversified miner Independence Group to undertake a 60sqkm digital map on the Fraser Range, 160km east of Norseman.
The survey will illuminate the geology around IGO’s new Nova Nickel Mine to a depth of about 5km, producing a 300cukm 3-D image containing around 800 million individual units of information, or voxels.
