Australian gold and copper explorer Torrens Mining (ASX: TRN) has announced, in conjunction with joint venture partner Coda Minerals (ASX: COD), further significant preliminary results from the ongoing IOCG drilling program at Emmie Bluff Deeps, part of the Elizabeth Creek Copper Joint Venture Project in South Australia.
The JV has now completed four new wedge holes; two wedges from parent hole EBD2 and two from EBD3. A fifth wedge hole EBD2W4 is ongoing and is currently drilling an indeterminate thickness of chalcopyrite dominated mineralisation.
All of these new holes intersected copper-bearing sulphides at or about the target depths. The most significant intersections were in 3W3B and 2W3, which encountered:
- 3W3B: 36m of bornite-dominated mineralisation from 804m in its upper lode, followed by a second, lower, lode consisting of 10m of mixed chalcopyrite and bornite mineralisation from 955m, for a total of approximately 46m of mineralised core, extending the known copper-rich bornite zone approximately 70m further to the south-east; and
- 56m of chalcopyrite dominated mineralisation from 903m in EBD2W3.
This brings the total lateral extent of mineralisation encountered by the JV in its primary area of interest to an area of approximately 450m E/W and 250m N/S. Furthermore, incorporation of historical data suggests the potential for significant extension in multiple directions.
Though of a slightly lower tenor, mineralisation at a similar RL is known from historical drillholes SAE 3 (300m east of easternmost intercept) and SAE 4 (730m NNE of northernmost intercept). The gravity anomaly also extends approximately a further 1,400m to the southeast beyond the southernmost mineralised intersection.
Both field logging and hand-held XRF measurements have confirmed the presence of material amounts of copper-bearing sulphides throughout the reported intervals. The JV is preparing all mineralised intercepts for assay.
Additional visual observations confirm that the copper bearing mineralisation extends over a laterally extensive area with significant new intersections including:
- 24.5m of chalcopyrite and 17m of bornite dominated mineralisation from 890m and 930m respectively in EBD2W2; and
- 8m from 816m and 4.5m from 833m of bornite dominated mineralisation (split by a fault zone) in the upper lode and 29.5m of blebby chalcopyrite and bornite from 903m in the lower lode of EBD3W2A.
These results by themselves are highly encouraging; however, when taken in context with previous drilling they clearly demonstrate that the mineralised envelope extends to the north and south-east, with the mineralisation remaining open in both directions.
The JV plans to test both these directions but will prioritise the testing of extensions of the bornite-dominated core to the south in the short term with the next planned hole targeting an extension of approximately 250m in the south-east. Results from this hole are anticipated early in the New Year.
Torrens Managing Director Steve Shedden said:
“We are pleased to see the progress that has been made by the joint venture at Elizabeth Creek and in particular through this IOCG drilling program at Emmie Bluff Deeps.
“As our understanding of the project grows, so too does our confidence that Elizabeth Creek has the potential to become a significant Australian copper operation.
“We look forward to providing further updates on assay results as they come into hand.”
