Fiery Creek Project
The Fiery Creek Prospect consists of the historic Fiery Creek and Macanally gold and copper working from the early 1900’s that extend for over 7km.
Historical mining at the Fiery Creek & Macanally Prospects was reportedly only mined down to a level of approximately 40 foot (or 12 metres) below surface. This is thought to coincide with the depth of oxidation, thus leaving behind the sulphide dominant ore below. The sulphide dominant ore would have been much harder to treat during the time of mining in the 1890’s as the processing would have been substantially more complex.
Ironbark considers there is a high potential to locate economic grade mineralisation in the area as to date there has been limited drill testing of the lodes below the historically mined material. The extent of the historical workings indicates a good probability that sufficient tonnes to be of interest could be located in the area.
Ironbark has completed rock chip sampling along the line of workings which returned spectacular grades, including;
- Peak gold results include 253.0 g/t, 94.8 g/t, 91.5 g/t and 53.4 g/t
- Peak copper results include 14.9% , 7.6% and 6.6%
Nine diamond holes were drilled at the Fiery Creek workings in 1988 by Horizon Resources Limited (Horizon) which targeted deep IP anomalies, rather than mineralisation directly under the workings. However, several low grade mineralised zones were intersected including;
- F001: 1.09m @ 3.6 g/t gold from 30.56m
- F006: 2.00m @ 1.7 g/t gold from 35.70m
- F009: 0.50m @ 2.4 g/t gold from 41.20m
Horizon drilled 138 shallow RAB drill holes in 1990, typically to a depth of 20 metres (minimum 17 metres to a maximum of 21 metres) for a total of 2,763 metres around two of the more accessible regions of workings (Figure 1). Highlights include;
- FCR039: 3m @ 6.7g/t gold from 6m
- FCR095: 4m @ 4.0g/t gold from 16m
- FRC125: 1m @ 7.2g/t gold from 9m
Systematic drill testing underneath the workings, especially around the recent higher grade rock chip samples, has not been completed and presents an exciting exploration opportunity.
