SRK uses UltraGPR for iron sands exploration in Greenland

SRK Exploration Services of Cardiff, Wales, has used UltraGPR technology to map an iron sands deposits along the north-west coast of Greenland.  The site is extremely remote and is only accessible during the summer.  This site marks the northernmost (and likely most remote) location UltraGPR has been used.

 

Continued GPR development at Weipa, Queensland

Groundradar continues to develop custom radar instruments and processes for Rio Tinto’s Weipa operations in Queensland, intended to accurately and consistently map the thickness of bauxite atop an ironstone underburden.

Dr. Francke to present paper at SAGA 2017 Conference in Cape Town

Dr. Francke will present a paper entitled “Realistic GPR Performance” at the South African Geophysical Association’s Conference in Cape Town in September.  The paper addresses claims made of extraordinary and unrealistic radar performance by some vendors in Southern Africa and Australia using Russian/Ukrainian “megawatt” radars.  The paper clearly shows that these performance claims are entirely outside of the bounds of accepted physics and such instruments can pose a significant safety risk.

Extensive coltan exploration project continues in Sierra Leone

AMR Gold is using UltraGPR technology to map coltan bodies in a remote part of Sierra Leone.  To date, the UltraGPR has been able to consistently map these bodies to depths of over 70 m.  Regardless of the rugged conditions, over 40 km of survey distance has been collected over a grid, showing the dip and strike of the coltan targets in 3D.
