Norseman Gold Exploration Results
Auroch Minerals Limited (Auroch or the Company) is pleased to announce positive results from reconnaissance mapping, rock chip, and soil sampling programs at its wholly owned Beete Gold Project (P63/1646) and Peninsula Gold Project (P63/1694) near Norseman, Western Australia (Figures 1 & 2).
Best results from a total of 22 rock chip samples collected from the projects included: 13.30g/t Au, 13.00g/t Au, 8.76g/t Au and 8.59g/t Au. Additionally, a total of 25 Hectares was mapped and 44 soil samples analysed for multi-elements by portable XRF (45 elements).
CEO Dr Andrew Tunks Commented "The positive results we have received from the rock chip sampling are encouraging and worthy of further follow up and we are continuing to investigate the potential of these well mineralised veins."
Rock chip sampling
A total of 22 rock chip samples were collected from P63/1646 and P63/1694 (Figure 3 and Table 1). Rock chips were selected by identifying quartz rich and/or altered material from outcrops, around old shafts/workings, or from historic trenches. Samples were submitted to ALS Laboratories in Kalgoorlie (WA) for gold determination by 50g fire assay. Also, the samples were analysed for an additional 45 elements by portable XRF (Niton XL3t Analyzer) using "Test All Geo" mode which is suitable for rapid analysis of major, minor, and trace elements in geologic samples.
Beete Gold Project (P63/1646)
The historic workings on the Beete Gold Project were visited and hand specimens collected for assay. Gold mineralisation is hosted within a narrow quartz vein, and sometimes in the adjacent hanging and/or footwall shear. Best results were: 13.00g/t Au, 3.79 g/t Au, 3.31 g/t Au, and 2.00 g/t Au (Figure 3). The vein where observed in open stopes is only narrow, but results confirm it can host considerable grade. There is obvious potential to the northeast which warrants follow up with possible trenching and reconnaissance AC/RC drilling.
Peninsula gold Project (P63/1694)
On the Peninsula Gold Project mineralisation is observed to be associated with north-south trending quartz veins which dip at angles of 60-80 degrees to the east. Best results were: 13.30g/t
Au, 8.76 g/t and 8.39 g/t Au (Figure 4). Again, the vein where observed in open stopes/shafts is only narrow, but results confirm it hosts considerable grade. Work will now focus on previous studies around the 1-2m wide milky quartz vein which is the target of the sizeable N-S slot historically excavated, and the area of significant mineralisation in rock chip sampling.
Reconnaissance mapping
An area of 25 Hectares was mapped during the field program. East-West traverses were conducted across the tenements recording: historical workings, historic drill hole locations, outcropping lithology, alteration, and mineralisation.
Beete Gold Project (P63/1646)
The historic workings on the Beete Gold Project were visited and hand specimens collected for assay. Gold mineralisation is hosted within a narrow quartz vein, and sometimes in the adjacent hanging and/or footwall shear. The vein conforms closely to the attitude of the host lithology quartz-rich arenites and quartz-feldspar-amphibole schists.
Peninsula Gold Project (P63/1694)
On the Peninsula Gold Project, mineralisation was observed to be associated with north-south trending quartz veins which dip at angles of 60-80 degrees to the east. A major quartz reef extends for the length of the tenement. At the north end of the tenement the main reef appears to have been faulted, and the geology is complicated by drag folding associated with faulting.
Soil sampling
A total of 44 soils samples were collected and analysed by portable XRF (Niton XL3t Analyzer) from P63/1646 and P63/1694. Currently 'Z' score plots for all elements are being prepared and analysed by the exploration team and will be released to the ASX once the evaluation is completed. The sampling grid was 150m x 50m across the tenements and holes were excavated to 30 cm depth, with the top 10 cm discarded. The sample was then sieved and the fine fraction (
Conclusion
This work has shown that prospectivity remains on these licences and Auroch staff will be developing a plan to continue the evaluation.
