|Geophysics and Drilling Collaborations Program 2021 Resourcing the Territory EL 32283 and EL 32284 Airborne Geophysics Survey Report, Georgina Basin, NT
|Title Holder / Company:
|Knox Resources Pty Ltd (Knox or the Company) applied for and was successful in seeking exploration grants with the Northern Territory Geological Survey (NTGS) as part of the Round 14 of the 2021 Geophysics and Drilling Collaboration and the Northern Territory Government's four-year 'Resourcing the Territory' initiative. The co-funding grant was applicable to Exploration Licence (EL) 32283 and EL 32284 located within the Georgina Basin, Northern Territory, to acquire an airborne magnetic survey based on a traverse line spacing of 100 m and a survey area of circa 1,100 km2. Both titles are held by Knox on a 100% basis. Knox is a wholly owned subsidiary of Greenvale Mining Limited, a publicly listed company on the Australian Securities Exchange (ASX) with ticker code GRV. EL 32283 was granted on 23 September 2020 and covers an area of approximately 402 km2 while the adjoining EL 32284 is under application and covers an area of approximately 711 km2. Both Knox's Georgina Basin tenements cover part of the interpreted south-eastern extension of the highly prospective Warramunga Province under Georgina Basin cover sequences. Exploration is focused on IOCG style mineralisation with the Warramunga Province basement, as well sediment-hosted copper and/or zinc in palaeo-Mesoproterozoic basin successions. Pre-competitive geoscience studies in the area by Geoscience Australia and NTGS, and a recent Geoscience Australia IOCG 'Prospectivity' map (Skirrow et al., 2019) highlighted the area as being highly prospective for Tennant Creek-style IOCG mineralisation. Knox commissioned MAGSPEC Airborne Surveys Pty Ltd. (Magspec) to undertake the geophysical survey over EL 32283 and EL 32284. The field acquisition commenced on 18 September 2021 until 2 October 2021 utilising a Cessna 210, a specially modified aircraft for this type of survey. The crew was based in Barkly, Northern Territory for the duration of the survey. Field data were processed, and inversion geophysical modelling undertaken by Resource Potentials Pty Ltd (Resource Potentials) in Perth, with the geological interpretation, 3D geological modelling and drill hole targeting undertaken by SRK Consulting (Australasia) Pty Ltd (SRK). A total of 12,977 total line kms were acquired during the survey. The airborne magnetic survey data has provided a better understanding of important structural corridors, distribution and architecture of prospective geological horizons, potential fluid sources as well as provide greater confidence for drill targeting present in EL32283 and EL32284. Several target areas have been identified as a result and represent follow-up drill ready targets for Knox.
