Pinjin Project, Yilgarn WA

• Exploration continued on the Pinjin project within the Yilgarn Province, WA. The Pinjin Project is located 150 km northeast of Kalgoorlie, comprising a large tenement package of 19 exploration licences (1,164 km2) for 416 blocks (Figure 3.0).

• The final assay results were received for the remaining 100 holes from a 313 hole (PJAC01548 to PJAC1860), 20,304 metre aircore drill program completed in Q4 June FY18 (Figures 3.1 to 3.4). The drilling tested 6 targets, including infill and extension drilling at Graham’s Find prospect, southeast Yindi station area, the Old Homestead Prospect, part of the Mulgabbie trend and reconnaissance drilling at two new geological targets in the western tenements.

• Aircore drilling results for southeast Yindi station extended the previously defined north-northwest striking, semi-continuous zone of anomalous gold (≥ 50 ppb Au), lead, bismuth and tungsten along strike to the north (Figure 3.2). The mineralised trend now extends for over 7km.

• A 348 hole (PJAC1861 to PJAC2208), 14,022 metre lake aircore drilling program was completed in Q1 September FY19. The program tested 5 targets under Lake Rebecca, including Graham’s Find, the Mulgabbie trend and three geophysical targets. Final assay results were received for holes PJAC1861 to PJAC1912 and preliminary composite results for holes PJAC1913 to PJAC2208. Best results received to date (all intercepts downhole, details in Figures 3.1, 3.3 and 3.4 and Table 2) include:

o PJAC1939: 4 m @ 559 ppb Au from 52m, and

o PJAC2144: 4 m @ 558 ppb Au from 28m

• Lake aircore drilling at Graham’s Find tested the southern 1.4 km strike length of the trend that is located under Lake Rebecca. Preliminary results have assisted in defining a 3.4 kilometre long, north-northwest striking zone of anomalous gold (≥ 100 ppb Au) and arsenic (≥100 ppm As) in bedrock (Figure 3.3). A preliminary PJAC2073 intercept of 8 m @ 1853 ppb Au is associated with a mixture of transported material and the top few metres of weathered bedrock. Lake aircore drilling across the Mulgabbie trend identified similar geology as seen along strike to the north and south. Anomalous gold (≥ 50 ppb Au) and arsenic (≥50 ppm As) was identified in mafic chlorite schist (Figure 3.4). Lake aircore drilling of the geophysical targets located in the central Pinjin tenements failed to identify any anomalous gold in bedrock.
