Kavango Resources plc, Botswana: SkyTEM makes a huge difference

/in , , , , /by

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.”

A SkyTEM312 HP survey to begin for Kavango Resources in Botswana

/in , , /by

The survey will be flown with SkyTEM’s innovative new generation 312 HP (High Power) technology for deep exploration. This High Power system, with a peak moment up to 1,000,000 NIA, is optimized to provide an exceptional depth of investigation due to the high moment (HM) mode with high current and low base frequency of 12.5 Hz. This system has only been on the market since 2017 and therefore, represents a major advance in AEM systems.

Michael Foster, Chief Executive Officer of Kavango, commented:

“We are pleased to be able to announce the start of Phase 2 of the AEM Survey. SkyTEM’s new High Power system will allow us to investigate the potential for Cu-Ni-PGE rich sulphide orebodies at much deeper levels and with greater resolution than older systems”.

The recent SkyTEM Africa Seminar, hosted by our Regional Sales Manager, Christina Hutchinson, was once again thé event to attend. This took place at The Pivot Conference Centre, Southern Sun Montecasino Hotel in Johannesburg, South Africa on September 13, 2018.

The agenda: a presentation on a truly innovative new generation SkyTEM312 high power electromagnetic system launched in 2017 and a case study from the Areachap belt in South Africa presented by SkyTEM’s CEO, Dr Flemming Effersø, followed by a presentation titled “SkyTEM – Burning the candle at both ends” presented by SkyTEM’s guest speaker, Mr Cas Lotter, Managing Director at Spectral Geophysics.

Namibia Critical Metals identifies multiple targets from SkyTEM EM Survey

/in , , , /by

Namibia Critical Metals has issued a press release regarding the identification of multiple targets from SkyTEM EM survey over Kunene Cobalt-Copper Project.

  • SkyTEM airborne electromagnetic and magnetic survey covering 4,200 line kilometers has been completed.
  • Preliminary data shows prolific number of conductors in a variety of geological settings.
  • Priority target areas identified along 20 kilometers of interpreted DOF extension; along 15 kilometers of the Okanihova lineament; and as isolated targets at Okanihova East and Olulilwa Southwest.
  • Evalution of statebound vanadium target with coincident EM.
  • First phase drill program will comprise 2,000 m diamond and 2,000 m reverse circulation drilling.

Kunene Co-Cu project area showing SkyTEM airborne survey area (white dash) and preliminary EM conductor picks for 5-10 channel and > 10 channels responses. Responses for < 5 channels not shown. Channel responses are provided in picovolts/meter. Background images is total magnetic intensity from the Namibian Geological Survey database combined with satellite surface topography.

SkyTEM survey for Ni-Cu sulphide anomalies for Orion Minerals in South Africa

/in , , /by

Orion Minerals in South Africa announces the commencement of regional exploration in the Areachap Belt, Northern Cape, South Africa.

  • 19 SkyTEM anomalies selected for initial follow-up
  • 17 anomalies coinciding with a paleo-seafloor setting selected to be tested as volcanogenic massive sulphide targets
  • 2 anomalies are associated with known Ni-Cu sulphide mineralisation. Regional target generation is ongoing, evaluating the remaining SkyTEM data over the Jacomynspan Complex
  • Geological mapping and ground EM surveys to define drill targets on the SkyTEM anomalies commenced mid-May 2018

Orion’s Managing Director and CEO, Errol Smart, commented:

“Given the significant number of new anomalies generated by Orion’s initial helicopter-borne Electro Magnetic (SkyTEM) survey over our regional landholdings in the highly-prospective yet underexplored Areachap Belt, in our view, the use of modern exploration tools has significantly enhanced the probability of exploration success. We look forward to drill testing multiple targets in coming months with the first drill holes scheduled to commence during June 2018.”

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.”

EM SkyTEM survey for Orion

 

SkyTEM has completed an airborne geophysical EM survey for Orion Minerals in South Africa. Preliminary results for magnetic and SkyTEM data have been received and reviewed. The survey succeeded in acquiring high quality data and initial indications are positive for the identification of priority follow-up targets. Once targets have been ranked, Orion intends to test for Zn-Cu rich volcanogenic massive sulfide (VMS) and Ni-Cu magmatic deposits.

The survey demonstrates the value of applying modern airborne EM methods in the highly prospective Areachap Belt. Numerous AEM anomalies were identified during a preliminary review of the data by Orion’s Perth based geophysical consultants, Southern Geoscience Consultants. In addition to the AEM data, the accompanying magnetic data will significantly improve our understanding of the geology and structure in this area of poor outcrop.

Highlights include:

  • A 962 sqkm high power SkyTEM airborne EM survey completed on 24 January 2018
  • 6,018 line km of flights covering the survey area have been completed
  • Numerous discrete anomalies appear in the preliminary data set
  • AEM anomalies detected over known Zn-Cu VMS and Ni-Cu intrusive deposits
  • A number of AEM anomalies coinciding with a paleo-seafloor, offer immediate follow-up targets

Orion’s Managing Director and CEO, Errol Smart, commented:

“The results from our advanced airborne survey are extremely gratifying and are providing encouragement for continued exploration using modern techniques in the highly prospective Areachap Belt. We look forward to drill testing the highest priority targets in 2018.”
