Desktop studies revealed the Ninghan tenements were lightly drill tested for gold and base metals mineralisation with most past exploration focused on the Endeavour Shear (E59/2080). Historical RAB drilling at the Endeavour prospect defined supergene enrichment up to 40m thick containing mostly low-grade gold mineralisation with one intercept of 3m @ 1.95g/t in the northernmost hole. Past soils and RC drilling (20 holes) at the Highway prospect (E59/1692) identified anomalous mineralisation in hole HWR017 of 1m @ 7,500 ppm Ni, 1,250 ppm Cu, 448 ppm Co.
The Ninghan aircore drilling programme, undertaken in December 2018, targeted the Endeavour and Highway prospects. Drilling along the Endeavour Shear was focused on defining the extent of mineralization to the north-east. Drilling at the Highway prospect was designed to identifying potential gold and base metal mineralization in the northern extent of the folded mafic/ultramafic volcanics which contribute to a magnetic high in the area.
Fifty holes were drilled for a total of 1,786 metres and 459 samples were collected. All holes were oriented -60⁰ towards the west and drilled to blade refusal. The 4m composite samples were submitted to Genalysis Perth for ICPMS 33 element analysis.
The Endeavour drilling verified and infilled anomalous gold mineralisation observed over the 900m of strike (Figure 17, 18 and Table 5). These results are from infill 200m drill lines. After initial challenges drilling through the near surface silcrete +/- ferricrete horizons drilling intersected intensely sheared talc chlorite schist. Single metre re-sampling of the mineralised 4 metre composite samples were later collected and assayed.
