IOCG mineralisation extended at Torrens Mining’s (ASX: TRN) Emmie Bluff Deeps, shares preliminary drill results


  • The Company released further substantial preliminary results from the Emmie Bluff Deeps IOCG drilling program.
  • The latest results revealed broad copper-sulphide mineralised intercepts at four holes extending the mineralised envelop to the north, east and south.
  • Visual estimates of the five drill holes have already been released, while assay results are yet to be released prior to Christmas 2021.

Gold and copper-focused exploration company Torrens Mining Limited (ASX: TRN) reported further substantial preliminary results from the ongoing Emmie Bluff Deeps IOCG drilling program at the Elizabeth Creek Project.  The project is the subject of a joint venture with Coda Minerals Limited (ASX:COD) with Torrens holding 30% and Coda, the Joint Venture Manager and Operator, holding 70%.

The latest preliminary visual results reveal broad copper-sulphide mineralised intercepts in four diamond drillholes namely, EBD2W2, 2W3, 3W3A and 3W3B, extending the mineralised envelop to the north, east and south. Furthermore, the results highlight that the mineralisation remains open in these directions. All the completed holes intersected copper-bearing sulphides at or around its final depths.

The latest significant visual results included –

  • EBD2W3 - 56m of chalcopyrite-dominated mineralisation from 903m
  • EBD2W2 - 24.5m of chalcopyrite and 17m of bornite-dominated mineralisation from 890m and 930m, respectively
  • EBD3W3 - 45m of bornite-dominated mineralisation

Among all the results, the most significant one was recorded at the EBD3W3B wedge hole, which recorded 36m of bornite-dominated mineralisation from 804 metres in its upper lode and a lower lode with a total of 10m of mixed chalcopyrite and bornite mineralisation from 955m.

The latest results extended the total lateral extent of mineralisation at the primary area of interest to 450m east-to-west and 250 metres north-to-south. The historical data suggested the potential for substantial extension in multiple directions.

Assay Results and Maiden Resource estimate for Emmie Bluff

Visual estimates of five drill holes have now been released, with confirmatory assay results expected to be released prior to Christmas 2021. In the last two months, the company focused on testing and extending the chalcopyrite and bornite-dominant mineralisation.

Chris Stevens, the CEO of Torrens’ JV partner Coda, said the latest and previous drill program included nine holes with all of them returning materially significant intersections and have begun to display a trend of increasing thickness and tenor of mineralisation as the partners systematically pursue the bornite-dominant zone to the south-east.

The two JV partners expect to complete the transformational 2021 year with the release of assay results from several drillholes and a maiden JORC-compliant Mineral Resource estimate for the Emmie Bluff Zambian-style copper-cobalt deposit.

In October, the Company announced results from the earlier five drillholes, including two parent and three wedge holes, demonstrating an increase in the lateral extent of the mineralisation. One each from the parent (EBD2) and wedge (EBD2W2) holes have displayed a substantial increase in the thickness and intensity of visual sulphides. The wedge hole (EBD3W2) intersected 67m of intermixed bornite and chalcopyrite copper mineralisation for which, assay results are pending.

Previously in June 2021, Coda intersected 200m of intense IOCG alteration that included ~50m of copper sulphide mineralisation in the first diamond hole (DD21EB0018) at the Emmie Bluff Deeps IOCG target.

Torrens’ shares traded at AU$0.145 a share on 7 December 2021 increasing ~3.57% against the previous close.
