No field work was performed on the three subject licences during the period 2008-2010 inclusive. During 2010, Dominion Gold Operations undertook a desktop evaluation of the possible iron ore potential of the licences. During 2011, the licensee negotiated a joint venture agreement with Australian Metals Group Limited (AMG), who were planning an exploration programme to evaluate the iron ore potential on four Dominion Gold Operations' exploration licences (EL 4015, EL 4402, EL 4237 and EL 4238). Completion of the JV agreement became delayed pending AMG being able to negotiate exploration access into the Woomera Prohibited Area; consequently, no field work was carried out on any of the licences during the 2011-2012 reporting period. A 100% transfer of project ownership from Dominion Gold Operations Pty Ltd to Australian Metals Group Ltd was effected on 29/11/2012. During the following eighteen months between 17/12/2012 and 15/6/2014, AMG acquired a detailed airborne magnetic/radiometric/DTM survey over ELs 4015 and 4402, performed field geological mapping and minor soil calcrete geochemical sampling, and drilled 19 angled RC exploratory holes for 2652 m to test the Bulgunnia magnetite prospect on EL 4015/5235. At the start of the work programme, during August 2013, a 6625 line km helicopter-borne aerial geophysical survey was flown over portions of both the Bulgunnia and Labyrinth tenements along SE-NW or N-S flight lines 100 m apart, using a 20 m mean sensor height above the ground surface, to map the distribution of subcropping Archaean BIF metasedimentary strata. On EL 4015 Bulgunnia, the 3880 line km of survey data outlined a 4.5 km strike length of BIF folded into a SW-NE trending synclinorium, with the NW limb being partly displaced by a NW-SE fault. Repetition of the BIF by large scale parasitic folding was interpreted to have occurred in the keel of the synclinorium. Next, in October-November 2013, AMG drilled 19 angled exploratory RC holes to depths of between 130-150 m to test the BIF for its iron ore potential. The holes were drilled at 80 m intervals along short traverses spaced 400 m apart. They outlined a magnetite-rich BIF body carrying between 30% and 54% Fe which is more than 160 m thick, and is overlain by 40 to 60 m thickness of weathered overburden. 1409 drill cuttings samples were submitted for laboratory assaying, and subsequently, 411 samples from selected hole depth intervals underwent Davis Tube Recovery (DTR) magnetic separation analysis to determine their magnetite content. The results obtained suggested that a clean, high grade iron ore concentrate could be separated from the pulverised rock with a likely 30-35% mass recovery. The magnetite concentrate has low levels of natural contaminants. 1:1000 scale geological mapping of the Wilgena Hill Jaspilite at Bulgunnia was conducted by AMG while the drilling campaign was taking place there. Only sparse and very small (20%. It was believed by AMG that its Bulgunnia magnetite occurrence has similar geological and mineralisation characteristics to those of WPG Resources' Giffen Well magnetite occurrence located 7 km to the north-east, although the former is likely to be of higher grade. During the 2015-2016, 2016-2017 and 2017-2018 joint reporting years, no work was done. No work was performed on the tenements EL 6045 and EL 6085 from 2017 to their expiry in January 2023.
