Infill Magneto-Telluric Surveying to Proceed at Maslins
Infill Magneto-Telluric Surveying to Proceed at Maslins
Adelaide, Nov 22, 2017 AEST (ABN Newswire) - Investigator Resources Limited (ASX:IVR) is pleased to announce it will be participating in a magneto-telluric ("MT") geophysical survey over the Maslins iron oxide copper gold ("IOCG") target in the Carrapateena district of South Australia (see Figure 1 in link below). This will advance the understanding of the Maslins target at a small cost to the Company and will assist a decision to drill the target during 2018 while Investigator is focussing on drilling the Paris silver extensions and the Nankivel porphyry copper-gold target.

During 2006 to 2014, researchers recognised an upwards plume of MT conductivity beneath the giant Olympic Dam IOCG deposit. This provided the breakthrough concept of deep-seeing MT being able to map metal tapping structures as vectors to undiscovered IOCG deposits. A national (AusLAMP) survey on coarsely spaced MT stations subsequently showed a deep MT conductivity corridor connects the Prominent Hill, Olympic Dam and Carrapateena IOCG deposits and extends southwards into the Maslins area (see Figure 1 in link below).

The Maslins area was pegged by Investigator as the revised and under-explored extension of the Olympic Dam IOCG belt. The Maslins target was modelled from existing gravity data as a large body of the right size and density to be a substantial IOCG target with an acceptable depth to top of about 600 metres below the surface (IVR ASX announcement: 15 February 2016). Investigator perceives from the coarse AusLAMP data that there is potential for a prospective upward MT vector towards Maslins similar to the well-defined vector directed towards Olympic Dam (see Figure 1 in link below). The Maslins target has the potential to fill the substantial gap in sizes between the Olympic Dam deposit and the smaller Prominent Hill and Carrapateena IOCG deposits.

Government agencies Geoscience Australia ("GA") and the Geological Survey of South Australia ("GSSA") are preparing to undertake an infill MT survey within the next two months of the Carrapateena section of the MT corridor that includes the Maslins area. To fast-track the evaluation of the Maslins IOCG target, Investigator will undertake a small amount of additional MT surveying in January to ensure the interpreted target vector is adequately detailed to advance the assessment of the Maslins gravity target.

About Investigator Resources Ltd

Investigator Resources Limited (ASX:IVR) is a metals explorer with a focus on the opportunities for greenfields silver-lead, copper-gold and other metal discoveries in South Australia.

The Company's priority is progressing the development pathway for the Paris silver project with the preparation of a pre-feasibility study. The Paris Mineral Resource Estimate is 9.3Mt @ 139g/t silver and 0.6% lead, comprising 42Moz of contained silver and 55kt of contained lead, at a 50g/t silver cut-off. The resource has been categorised with an Indicated Resource estimate of 4.3Mt @ 163g/t silver and 0.6% lead for 23Moz contained silver and 26kt contained lead, and an Inferred Resource: 5.0Mt @ 119g/t silver and 0.6% lead for 19Moz contained silver and 29kt contained lead.

The Company has applied an innovative strategy that has developed multiple ideas and targets giving Investigator first-mover status. These include: the Paris silver discovery; recognition of other epithermal fields and the associated potential for porphyry copper-gold of Olympic Dam age; extending the ideas developed at Paris-Nankivel and using breakthrough government Magneto-Telluric surveying to rejuvenate targeting with the Maslins IOCG target as the next priority drill target.
