Groundradar’s Australian partners, Core Geophysics, has undertaken a series of extensive surveys in rural Western Australia to map paleochannels anticipated to contain diamonds for POZ Minerals. POZ has published an excellent video explaining the exploration program using UltraGPR here: https://www.youtube.com/watch?v=UeTNv5scIJU. The video also discusses failed attempts using consumer-grade radar systems to map the paleochannels.
Groundradar has had extensive experience around the Mt. Nimba iron ore deposits in Guinea and Liberia, having used UltraGPR in 2011-2012 to map detrital canga deposits to over 60 m. A new project will use UltraGPR to map BIF occurrences in the region and is expected to continue for two months.
Following from extensive work within the Sewa River conducted by Groundradar in the late 1990s through 2001, 2003, 2004 and 2008, Groundradar has commenced a large survey using UltraGPR technology within the Sewa River to map potholes, the thickness of gravel beds and the presence and thickness of hardpans with the active river channel.
Groundradar’s partner in the Caribbean, Geo-Edge Jamaica, has completed a large utilities detection project along the famous “Hip Strip” through downtown Montego Bay. The survey used a multi-channel GPR system to map utilities and pavement structure to depths over over 2.5 m in 3D using differential GPS.
Groundradar conducted extensive exploration projects with UltraGPR in 2011 and 2012 for bauxite and phosphates in Saudi Arabia. The client has recently invited Groundradar to return to test the latest UltraGPR iteration on new, deeper, deposits.
UltraGPR has been used on lithium exploration projects in Ontario and Quebec with excellent penetration and profile resolution. Further expanded surveys are expected to be conducted in the coming months.
A geotechnical investigation using long-range GPR has been performed at the Jadar lithium project in Serbia for Rio Tinto. The results are encouraging and further work may be performed during the summer.
With Groundradar’s dramatic growth in the last six months, PDAC afforded new partners an opportunity to discuss the implications of new radar technologies to their exploration and development projects. Significant interest was shown in Groundradar’s deep GPR technology, as well as borehole radar instruments.
Groundradar first visited Koniambo when it was a Falconbridge exploration project in 1997-98, and Dr. Francke conducted a large portion of his MSc research on Koniambo and Goro. 20 years later, Koniambo is re-examining the application of long-range UltraGPR to map the lateritic weathering profile at their deposits.
Following from early trials using older GPR systems in 1999 and 2003 by Groundradar, a recent re-visit has been made to the Cerro Matoso Mine in Colombia to trial the latest UltraGPR technology. The results were encouraging, and further field work is scheduled for July.
