Duketon North Project
The Duketon North Project, located 160km north-northwest of Laverton, is situated 50km north of the 10Moz Moolart Well/Garden Well/Rosemont gold camp. The Project comprises one granted tenement with an area of 198km2. The Project targets gold associated with a 42km strike length of the Hootanui Shear, a major fault zone that separates the Kurnalpi and Burtville Terranes.
Outcrop is limited and the Project is dominated by thin (<2m) sand plain. Recent research suggests that the Hootanui Shear Zone is a long-lived (D1 to D5) crustal-scale structure that overlaps the three main gold mineralising events in the Eastern Goldfields Superterrane. The presence of ultramafic-hosted nickel deposits along strike from the Project is consistent with late reactivation of an early, deep-seated extensional structure.
Previous exploration is limited. No systematic historical geochemistry has been completed. Other magnetic lows adjacent to the Hootanui Shear may represent other remnant Archean greenstone, or possible areas of gold-associated alteration. The aeromagnetic data also indicates several north-east and north-west-trending cross structures that are potentially favourable for localising gold mineralisation. The Duketon North Project covers a major crustal shear and is located along strike from known gold and nickel mineralisation. Minor previous exploration has confirmed the presence of previously unexplored greenstone and there is potential for greenstone or granite-hosted gold mineralisation.
During 2012, Breaker acquired and reviewed high resolution satellite data and a 6,283 line km detailed aeromagnetic/radiometric survey was flown to provide baseline data for structural analysis. Reconnaissance mapping undertaken in the December 2014 quarter progressed geological understanding of the area. An orientation soil survey was conducted in early 2015. The soil program identified a coherent 4km x 1.2km soil anomaly (+3ppb gold cut-off) that is associated with anomalous molybdenum, arsenic, copper and lead. The main soil anomaly is open to the south, with smaller anomalies to the east that appear to correspond with rotated (dilatant) segments of the shear package and coincides with a prominent bend in the greenstone sequence at semi-regional scale and drag folding adjacent to each of the major shear zones confirms east-block-north (sinistral) fault movement. In consequence, multiple northwest-trending structures and geological contacts in the soil survey area are dilational and therefore have excellent potential to host gold. A maiden aircore drilling program in July 2016 failed to identify significant gold mineralisation.
