Kavango Resources plc, Botswana: SkyTEM makes a huge difference

Chief Geologist Mike Moles from Kavango Resources states:

In the past, the main problem with the lower frequency surveys was noise. This was mostly due to the vibrations caused by the helicopter, and particularly that associated with wind-shear. After the disappointing depth penetration of the VTEM system, we learnt that the Danish company SkyTEM were claiming to have solved the noise issues with a 12.5 Hz frequency system. Further enquiries and endorsements by companies that had used the system convinced Kavango to see if this new system would be available for our Phase 2 survey.

 The added depth penetration of the SkyTEM system has made a huge difference to what we can “see” below the surface. It is like being able to see the whole body rather than just the top of its head.”

SkyTEM survey for Namibia Rare Earths Inc.

Kunene Co-Cu Project Area showing planned airborne surey area and geochemical anomalies for re-analysed soil samples from closed spaced sampling grid

Namibia Rare Earths Inc. has announced in a press release that it has contracted SkyTEM Surveys ApS to carry out a detailed airborne electromagnetic (EM) and magnetic survey covering all the previously identified cobalt targets on its Kunene Cobalt-Copper Project in Northern Namibia. The survey will cover over 600 km2 and comprises 3,700 line kilometers to be flown with a helicopter-borne time-domain electromagnetic system at a flight line spacing of 200 m. The objectives of the survey are to detect conductive horizons and sulphide accumulations associated with cobalt-copper mineralization to depths of 300-400 meters, and to assist with geological mapping and structural interpretations.

The powerful SkyTEM312 system is currently being mobilized from Denmark, and the survey is scheduled to be completed by June 30. It will be installed on an Astar 350 B3 helicopter operated by Savannah Helicopters, who is an experienced provider of airborne geophysical services.

Don Burton, President of Namibia Rare Earths Inc., stated: “Our SkyTEM survey will be the first airborne EM survey over this prospective area. Sediment-hosted cobalt-copper deposits should respond well to electromagnetic methods. Based on what the surface geochemistry is showing us, the SkyTEM survey will undoubtedly deliver multiple targets for the budgeted drilling campaign.”

SkyTEM Method for Finding Diamonds in Angola

Finding diamonds with SkyTEM

Conductivity-Depth Image (CDI) showing thick conductive crater in-fill

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 quickly completes Geoscience BC Peace Project with SkyTEM312FAST

Peace_Project_Geoscience_BC

SkyTEM Canada Inc is pleased to announce completion of Geoscience BC’s Peace Project in northeast B.C.

The Peace Project, designed to provide sound technical knowledge of the region’s aquifers, is a collaborative effort involving the BC Oil and Gas Commission, the BC Oil and Gas Research and Innovation Society, ConocoPhillips Canada, the Ministry of Environment, the Ministry of Forests, Lands and Natural Resource Operations, the Ministry of Natural Gas Development, Northern Development Initiative Trust and Progress Energy Canada Ltd.,  with additional support from the Peace River Regional District.

All data acquisition, comprising approximately 21,000 line kilometres and covering 8,000 square kilometres was completed in only 43 days.  This exceptional production rate was achieved with SkyTEM’s breakthrough technology – SkyTEM312FAST, the world’s fastest helicopter-borne geophysical system.

Engineered with a rigid aerodynamic carrier frame SkyTEM312FAST remains straight and level during high-speed flight benefiting data quality as well as survey efficiency and economy. Dr. Flemming Effersoe, SkyTEM’s CEO, stated “it means a great deal to me to have SkyTEM selected for this important project and we are proud of what we accomplished in British Columbia in such a short time. Our team delivered accurate high resolution data every 48-72 hours throughout the project. Combined with our ability to detect subtle geological contrasts in the top 400 m, at 150 kilometres per hour, this technology is of significant value to the global mineral and oil & gas exploration communities as well.”

Contributing to the unprecedented SkyTEM data acquisition rate and quick completion of the project was the communications expertise of Mr. Reg Whiten, President of InterraPlan Inc., who worked closely with local First Nations, the SkyTEM field crew, Devbrio Géophysique Inc, who adjusted day to day flight plans to accommodate First Nations cultural events and hunting season requirements and the logistics support and skills of pilots from Bailey Helicopters Ltd.

Mr. Carlos Salas, Vice President, Energy at Geoscience BC said “the Peace Project has collected valuable information. Without the cooperation of everyone, especially the local community, the results would have been much different.”

Information from the Peace Project will serve as a key component of the Northeast Water Strategy by providing knowledge to enable the Strategy’s Enhanced Water Monitoring System. The Northeast Water Strategy is currently under development by the Provincial government with cooperation from Treaty 8 First Nations, local governments, regulatory bodies, and the resource sector.

SkyTEM appreciates the opportunity to map the earth’s critical resources and are proud to have played a role in this vital project.
