Abstract: | This Group Report, GR223, details the exploration activities performed by Kettle Rose Pty Ltd on Davenport licences EL 26529 and EL 26708 for the year ended 13 July 2013. After acquiring the tenement, Kettle Rose initiated the process of evaluating the mineral potential of EL 26529 and EL 26708 by examining the published research, historic exploration data and the current understanding of genesis of Proterozoic gold and wolframite in the Davenport Province. The main exploration objective was to determine if geophysical, geochemical and geological anomalies within the Ooradidgee Group reflect sub-surface occurrence of ironstone bodies which may host copper-gold mineralisation similar to the deposit at Rover Field. To achieve this objective, a geophysical consultant was commissioned to review available regional airborne geophysical data from NTGS and identify potential targets within the Davenport project that can be explored for economic occurrence of gold. This study highlighted ten areas for further investigations by ground geophysical and geochemical surveys. These areas were mapped by ground magnetic survey and with the collection of MMI soil samples. Modelling of acquired ground magnetic data accurately defined geometry of identified anomalies and suggested that anomalous responses are linked to the occurrence of shallow mineralised magnetic bodies identical to ones that exists at the Rover Field to the west of Tennant Creek. Interpretation of geochemical data, however, highlighted inadequacy of number of MMI samples collected previously over some of the anomalies particularly those with a single MMI soil line. To improve the resolution of geochemical and geophysical responses of these anomalies, areas 7, 9 and 10 in the western part of the tenement were followed-up with further MMI sampling and ground magnetic survey in 2012. This work assisted in further refining the geometry of these magnetic anomalies and their geophysical response suggested possible association with Rover-style gold mineralisation. Further geophysical modelling was undertaken in the current reporting period including 3D inversions. Due to delays in receiving an AAPA certificate the Company amended its strategy and postponed a proposed drilling program. Funding was redirected to a ground gravity program to determine if the magnetic targets have an associated gravity response, which could reasonably be expected if the targets represent ironstone mineralised bodies. A contract has been signed and the survey is expected to be completed prior to the onset of the 2013 northern wet season. |
