Highlights of the Geophysical Program include: Six 2.4 km-long Induced Polarisation (IP) & Magneto-Telluric (MT) geophysical survey transects completed across the
IP & MT surveys will test the porphyry mineralisation potential for the project, indicated by numerous long drill intersections of low-grade Copper-Gold mineralisation in altered granitic rock
Geological setting at Granite Flat is prospective for porphyry mineralisation, with strong potential for Cu-Au porphyry mineralisation presently untested. A WNW-ESE trending structural zone bears stark similarities to that of the Cadia Valley Cu-Au system
The project also hosts potential for other styles of mineralisation, such as breccia hosted Cu-Au, and higher-level gold veining
Preliminary interpretation of geophysical survey results anticipated shortly
Chairman,
Overview
Fender Geophysics was contracted to acquire Induced Polarisation (IP) and Magneto-Telluric (MT) geophysical survey data across the Granite Flat project. Recent drilling competed by Dart Mining at Granite Flat in
Dart Mining aims to test the prospective porphyry mineralisation system through the application of this geophysical program, consisting of six 2.4 km IP and MT survey lines situated across Cu-Au soil anomalies, drill holes demonstrating long Cu-Au intersections and across remanent magnetism anomalies identified in open-file aeromagnetic data.
This survey is the first application of the Advanced Geophysical Technologies gDAS-32 system in
Consequently, the Fender Geophysics field crew have worked exceedingly hard in difficult conditions, overcoming various hurdles to complete this survey, whilst demonstrating an inordinate amount of determination to complete the job without compromise; for these efforts, Dart Mining is incredibly grateful. Mackey Geophysics have been consulted for interpretation of IP and MT data, and to revise and interpret regional gravity and airborne magnetics datasets. A preliminary interpretation of these data is anticipated in the coming weeks.
Project Summary
The Granite Flat prospect is located nine kilometres southeast of
Previous explorers have targeted the area with geophysical surveys, rock chip, soil and stream sediment sampling, and drilling and trenching. Historic soil grids have established 8 strong Cu-Au anomalies that have been variably drill tested across the prospect. In total, 18 costeans, 52 reverse circulation (RC) and 19 diamond drillholes have been completed by previous explorers between 1986-1997 (
Mineralised zones at Granite Flat are hosted within the Banimboola Quartz Monzodiorite (BQM) igneous intrusion. The BQM has been broadly identified as hosting a porphyry style of Cu-Au mineralisation associated with I-type granitoid and sulphide veins, with alteration varying from silicic to argillic to propylitic, with moderate to high background copper (Hesp, 1974; Bolger et al., 1983; Ramsay & Vandenberg, 1986; Wilde, 1988). Monzonite intrusive bodies are often the host of porphyry systems in the Lachlan Fold Belt. Additionally, the Granite Flat prospect lies adjacent to the Gilmore Suture, a significant crustal-scale structure that is associated with the emplacement of several porphyry Cu-Au systems across the border in
