Specimen Well Resource
The Specimen Well gold deposit is located 44km north of the historic Gidgee mill. The current Inferred Mineral Resource Estimate for the Specimen Well deposit is 0.36Mt @ 2.0g/t Au for 23,000oz (Table A)[1]. The deposit is currently just over 170m long, 5 to 25m wide and has not been previously mined.
Gold mineralisation occurs in quartz veined, talc-tremolite-chlorite schist and quartz feldspar porphyry on a sheared mafic / sediment contact. Mineralisation strikes north-northeast, is sub-vertical to steeply west dipping, displays a steep south plunge, and remains open to the north and down plunge to the south (Figures 13 and 14).
Significant intersections (>30 Au gram x metres) from the deposit include:
- 11.0m @ 10.7g/t Au from 42.0m (SWRC040)
- 25.0m @ 4.3g/t Au from 33.0m (SWAC075)
- 37.0m @ 2.6g/t Au from 23.0m (SWAC063)
- 34.0m @ 2.4g/t Au from 33.0m (SWAC079)
- 14.0m @ 4.5g/t Au from 43.0m (SWRC080)
- 18.0m @ 2.8g/t Au from 57.0m (SWAC064)
- 9.0m @ 5.0g/t Au from 31.0m (SWRC099)
- 16.0m @ 2.3g/t Au from 89.0m (SWRC082)
- 5.0m @ 6.5g/t Au from 91.0m (SWRC095)
- 7.0m @ 4.5g/t Au from 5.0m (SWRC083)

Exploration drilling is targeting strike and depth extensions to existing mineralisation with the aim of increasing the current MRE.
