SkyTEM Survey in South Africa for Orion Minerals

The SkyTEM technology during survey operation (not on Orion projects)

Orion has contracted SkyTEM, a leading airborne electromagnetic (AEM) survey company headquartered in Denmark which offers state-of-the-art helicopter borne transient electromagnetic (TEM) and magnetic acquisition system, to fly an extensive (6,025 line km) TEM survey covering large portions of the Company’s Masiqhame and Disawell JV Project areas located in the Northern Cape.

The helicopter TEM survey will be flown with the highly innovative – SkyTEM312 high power technology for deep target imaging. This high power system, with a peak moment up to 1,000,000 NIA, is optimised to provide an exceptional depth of investigation due to the high moment mode with high current and low base frequency of 12.5 Hz. This breakthrough technology is aerodynamically superior to any TEM system on the market and as such, the data collected from the survey will contribute to the Company’s exploration success. The survey is scheduled to commence on 26 November 2017.

Light-weight carbon fiber frame

SkyTEM continues to deliver new technological advancements to the airborne EM industry with a combination of superior survey economics and exceptional exploration capabilities. The systems are designed to minimize costs and maximize results and will assist water agencies, geotechnical engineers and mineral exploration companies face and solve 21st century challenges.

The newly engineered SkyTEM306 HP and SkyTEM312 HP (High Power) systems are mounted on a revolutionary rigid and lightweight carbon fiber frame.

Learn more about the new break-through technologies here:

The new systems are specifically designed to:

  • Reduce exploration costs by combining fast flying (up to 150 km/h) with light-weight frames
  • Provide quick data turnaround so you can make survey decisions in real-time during surveys
  • Explore deeper and at higher elevations
  • Significantly improved signal-to-noise ratio achieved with higher dipole moment light-weight systems
  • Improved characterization of geology and conductors

Please contact SkyTEM for further details about the benefits of the two new revolutionary helicopter TEM system.

The recent SkyTEM Africa Seminar, was once again a huge success, hosted by our SkyTEM Africa Regional Sales Manager, Christina Hutchinson, whose mandate is new business development, developing new and maintaining existing long-term business relations.

The event was held at The Pivot Conference Centre, Southern Sun Montecasino Hotel in Johannesburg, South Africa on May 18, 2017.

The agenda comprised a presentation on the launch of SkyTEM’s new generation of time-domain electromagnetic (EM) systems presented by SkyTEM’s CEO, Dr Flemming Effersø. Proceeding, a presentation on a few SkyTEM case studies applicable to Mine Planning and Exploration presented by SkyTEM’s guest speaker, Mr Gavin Selfe, Consulting Geophysicist at GRS Consulting, followed by a networking opportunity with invited guests and SkyTEM’s strategic partner, Savannah Helicopters.

SkyTEM Method for Finding Diamonds in Angola

Finding diamonds with SkyTEM

C.L. (Tiaan) Le Roux and W.H.B. (Billy) Steenkamp have written a paper about Xcalibur Airborne Geophysics’ project for Catoca in Angola using the SkyTEM’s airborne EM and magnetic surveys for finding diamonds.

Airborne geophysical techniques are widely accepted and routinely used in the search for diamondiferous kimberlite intrusions, particularly if large areas need to be explored or if the kimberlites are covered by more recent Tertiary or Kalahari sediments and do not penetrate to the present day surface.

Since its inception about 12 years ago Xcalibur Airborne Geophysics has flown many high-resolution airborne geophysical surveys in a number of African countries for various diamond exploration companies. Among these are a number of recent surveys flown for Sociedade Mineira de Catoca LDA (Catoca) in 2013 in Angola.

Angola is the world’s fourth-largest diamond producing country after Botswana, Russia and South Africa. Apart from the well-known Catoca diamond mine in the Lunda Sul province, which is one of the largest kimberlite pipes in the world, Catoca together with partners Endiama and Prescol,hold a number of large very prospective exploration licenses in Angola. In spite of being in ‘elephant country’ for kimberlites, it remains a challenge to cost-effectively and successfully explore for economically viable prospects. The correct application of both magnetic and electro-magnetic (EM) airborne geophysical surveys forms an integral part of Catoca’s exploration strategy for finding kimberlites that contain diamonds.

The most cost-effective technique for first-pass exploration of large areas, particularly where access on the ground is difficult, is still airborne magnetic surveying. The key is to use state-of-the-art geophysical instruments on a robust, low-noise airborne platform and acquire good quality data along adequately spaced flight lines at the lowest safe flying height. Follow-up with airborne EM helps to differentiate, delineate and confirm targets for direct drilling.

Airborne EM data is acquired using the proven world-leader high-resolution helicopter-borne
SkyTEM system from SkyTEM Surveys Aps., Denmark. This system is mounted on a large
non-metallic hexagonal frame which is slung 35m below a standard Eurocopter B3 helicopter.

SkyTEM survey for groundwater mapping in Botswana

/in , , , /by

The International Water Management Institute (IWMI) has published an article about their groundwater mapping project over the Ramotswa Aquifer on the border between South Africa and Botswana.

“This is tremendously useful for us,” said IWMI’s Karen Villholth who leads the initiative. “By digitally mapping the subsurface in this way we can work out where the important aquifers are located, how large and deep they are, how they are delimited by other geologic formations. From this we can determine where it would make sense to further explore the aquifer through traditional means to identify good sites for drilling and managed aquifer recharge.”

The aim of the project is to generate new information about groundwater to facilitate its sustainable management and support water security and resilience for the two countries.
