Barton Gold Holdings Limited announced new high grade assays for the central 223 Deposit at its South Australian Tunkillia Gold Project (Tunkillia). The 223 Deposit hosts a JORC (2012) Mineral Resource of 965koz Au (26.1Mt @ 1.15 g/t Au) on 2.5km of strike (68% classified as Indicated Resources). Assays from the final 4 drill holes (total 742m) of the Tunkillia Phase 1 program confirm recent modeling suggesting a potential higher grade zone of mineralisation central to the 223 Deposit. Barton has also recently announced the establishment of two new shallow gold zones totalling 1.5km of new gold mineralised strike across the 223 North and Area 191 prospects, extending the total mineralised strike at Tunkillia by 60% to a total 4km. Shallow 250m Long High Grade Gold Zone: The high grade Area 223 gold zone presently spans some 250m N-S strike central to the 223 Deposit. Tunkillia Phase 1 drilling has infilled gaps in historical Resource drilling and further defined the contours of this zone which starts 40m below surface and trends to 175m depth toward its southern end. The northern end of this zone has not been drilled deeper than 75m, and the high grade zone remains open to extension in all directions. Consistent 50m Wide High Grade Mineralisation to 175m Depth: The central high grade zone at the 223 Deposit is comprised of consistent, broad mineralisation around 50m wide with drilling intersections grading significantly higher than the average 223 Deposit grade, showing Tunkillia Phase 1 drilling holes TKB0024 ? TKB0027. Only historical drilling intercepts grading in excess of 2 g/t Au are included in Figure 4. The high grade zone currently extends to 175m depth and remains open to further extension. Central Area 223 Drilling Background: Following acquisition of the Tunkillia Project in 2019 Barton commissioned a comprehensive analysis and remodelling of the 223 Deposit, which identified a number of deficiencies with historical modeling including a low outer wireframe threshold of 0.1 g/t Au no internal sub-domains. 3 This effectively expanded the outer boundaries and blurred the internal boundaries of the mineralised wireframe for a broader, diluted model with lower average grades. The 223 Deposit was therefore remodelled using appropriate subdomains, a higher outer wireframe threshold of 0.3 g/t Au and a cut-off grade of 0.4 g/t Au within a reasonable prospects for eventual economic extraction (RPEEE) optimised open pit.4 As a result, `smearing' and dilution of the resource grades between subdomains, and dilution of the model at the model periphery, were significantly reduced, allowing grades to reflect truer values. Multiple potential higher grade zones were also interpreted where mineralisation is bounded on its eastern margin by intrusive dykes.4 Tunkillia Phase 1 drilling in central Area 223 was designed to test the potential continuity of high grade gold mineralisation, and the nature of the key bounding structures.
