VTEM Survey Commences In Ashburton Basin
TechGen Metals Limited (ASX:TG1) has commenced a heliborne Versatile Time Domain Electro Magnetic (VTEMT Max) geophysical survey within the company’s highly prospective 100% owned Mt Boggola Project in the Ashburton Basin of Western Australia.
The Mt Boggola Project consists of two Exploration Licences (E08/2966 & E08/3269) which cover a combined area of 179 sq. km. The airborne survey at the company’s Station Creek Project which commenced last week has now been completed with results awaited.
The survey at the Mt Boggola Project will consist of approximately 320 line kilometres of surveying with nominal 200m spacing between flight lines. The survey is being flown by UTS Geophysics Pty Ltd and the data, once received, is to be processed and modelled by Russell Mortimer at Southern Geoscience Consultants (SGC). The airborne survey will cover the northern granted project area (E08/2996).
The VTEMTM Max system is an innovative and successful airborne electromagnetic system. The proprietary receiver design, using the advantages of modern digital electronics and signal processing, delivers exceptionally low-noise levels. Coupled with a high dipole moment transmitter, the result is unparalleled resolution and depth of investigation in precision electromagnetic measurements.
Historic drilling, rock chip and soil sampling and exploration completed by TechGen has identified areas of high-grade copper ± silver ± gold and outcropping copper mineralisation (malachite) within the project area. Several areas of anomalism are known and the VTEM-Max survey is being undertaken to identify possible sulphide mineralisation at depth across the project area.
XRD analysis has been undertaken on a single rock chip sample which assayed 48.7% Cu & 119g/t Ag. The results of the XRD analysis have indicated that in addition to the presence of copper oxide minerals (Malachite, Brochantite & Atacamite) that the copper sulphide mineral Djurleite is also present within the sample.
The VTEM survey is anticipated to take four to five days to complete.
