FRASER RANGE JV EXPLORATION PROGRAM UPDATE
KEY POINTS
-
First diamond drill hole of current program completed by IGO Limited (“IGO”) (ASX: IGO) on the Fraser Range Joint Venture’s Red Bull tenement, 30km south of IGO’s Nova Operation in Western Australia
-
Preliminary geological logging of drill hole 21AFDD116, targeting the RB_C moving-loop electromagnetic (“MLEM”) conductor shows no clear potential source for the modelled RB_C MLEM plate in the drill hole[1]
-
A follow-up downhole electromagnetic (“DHEM”) survey indicates a strong off-hole conductor of ~6,600S named “RBC_DHEM”, approximately 100m east of the drill hole
-
Prospective host rocks intersected below 410m, with patchy pyrrhotite-chalcopyrite in multiple, narrow mafic-ultramafic intrusives, assay results are pending
-
Diamond drill hole 21AFDD117 targeting MLEM conductor “RB_B” is in progress
Gold and base metals explorer Carawine Resources Limited (“ Carawine ” or “ the Company ”) ( ASX: CWX ) is pleased to announce an update to the diamond drilling program in progress at Red Bull, about 30km south of IGO’s Nova Operation in the Fraser Range region of Western Australia (Figure 3).
Red Bull is part of the Fraser Range Joint Venture between Carawine and IGO, with IGO managing and operating the joint venture. IGO currently holds a 70% interest in the joint venture tenements and is sole funding the exploration program to 30 June 2022 to earn up to an additional 6% interest.

ASX AND MEDIA RELEASE
8 November 2021
Commenting on the preliminary results from Red Bull, Carawine Managing Director David Boyd said:
“Despite IGO’s first diamond hole at Red Bull not finding a conductive source for the RB_C MLEM target, the identification of an off-hole conductor, prospective host rocks and traces of magmatic sulphides in the drill hole is significant and very encouraging. Any additional drilling will be planned after assay results are received, and more detailed modelling of the new off-hole conductor has been completed.
“We’re looking forward to the completion of the second drill hole in the current program, targeting the RB_B conductor.”
The first diamond drill hole in the current Red Bull diamond drilling program, named 21AFDD116, was completed at the Red Bull C (“RB_C”) target to a total depth of 692.5m. The drill hole was targeting a 5,200-5,500S MLEM plate at a depth range of 400 - 450m downhole, interpreted to be an accumulation of conductive Ni-Cu sulphides (Figure 1) (refer ASX announcement 19 July 2021).
The dominant rock types intersected in the drill hole are variably deformed metasedimentary and granitic gneisses, with a major brittle-ductile fault intersected at approximately 410m and extending to 440m downhole. From 615.5m to 626.6m depth, the drill hole intersected interconnected blebby and disseminated two-phase sulphides (pyrrhotite and chalcopyrite) (e.g. see Figure 2), with only minor conductance levels. These occur within altered mafic-ultramafic intrusives considered prospective for magmatic nickel-copper sulphide mineralisation (likely to be Snowys Dam Formation stratigraphy).
There was no clear potential source for the modelled MLEM plate observed in the drill hole.
Upon completion of the drill hole, IGO completed a DHEM survey, with the data showing a clear, well defined off-hole conductive anomaly. Initial modelling indicates that the new conductor (“RBC_DHEM”) is above and to the east of the drill hole, with the bottom edge about 100m away. The modelled RBC_DHEM conductor has very high conductance at ~6,600S: its dimensions are 170m x 250m, depth to the top is 150m, and it dips 50 degrees towards 145 degrees (refer to Table 1 and Appendix 1 for details).
Routine sampling of the drill hole for assaying is in progress. Any follow up drill targets will be based on further detailed DHEM modelling, geological interpretation and assay results.

About the Fraser Range Project
Carawine’s Fraser Range Project includes six granted exploration licences in five areas named Red Bull, Bindii, Big Bullocks, Aries and Big Bang; four active exploration licence applications named Willow, Bullpen, Shackleton and Zanthus, plus eight exploration licence applications subject to ballot; in the Fraser Range region of Western Australia (Figure 3).
The project is considered highly prospective for magmatic nickel-sulphide deposits such as IGO’s NovaBollinger nickel-copper-cobalt deposit, 30km north of the Red Bull tenements, and two recent emerging discoveries in the Central Fraser region by Legend Mining (ASX: LEG) at its Mawson prospect, and Galileo Mining Limited (ASX: GAL) with its Lantern group of prospects.
Carawine’s Fraser Range Joint Venture with IGO is over five granted tenements at Red Bull, Bindii, Big Bullocks and Aries. IGO currently holds a 70% interest in these tenements. Carawine has elected not to contribute towards the FY2022 Joint Venture program and budget of approximately $1.3 million, therefore if IGO completes the entire program as proposed, Carawine’s interest will be diluted from 30% to approximately 24%. The remaining tenements in the Fraser Range Project are held 100% by Carawine.

Appendix 1.1: 21AFDD116 Summary Geological Description (all depths down-hole)
Dominantly granitic rocks occur from the base of weathering to approximately 350m, above a biotite-garnet gneiss which extends to approximately 410m. From about 410m to 440m the hole enters a brittle-ductile fault zone, dipping at approximately 60deg. towards 128deg. There is no obvious potential conductive source material within the fault zone.
Below 440m, the hole entered a package variably deformed granitic gneiss and carbonate-altered metasediments. These have been intruded by numerous, narrow gabbroic/amphibolite units showing features interpreted to be the result of turbulent/dynamic interaction between carbonate sediments consumed by gabbro. This is interpreted as a favourable indicator of potential mineralisation, drawing similarities with the emplacement environment of the Nova-Bollinger deposit host rocks. Fine, minor pyrrhotite and chalcopyrite disseminations increase in abundance downhole.
At around 610m depth, the drill hole intersected interconnected blebby and disseminated 2-phase sulphides (pyrrhotite-chalcopyrite) within highly carbonate assimilated gabbro/gabbronorite intruding metasediment. Below this and extending to the end of the hole, a package of garnet-rich metasediment is intersected with minor, mafic derived amphibolite and occasional silicious mm scale banding.

Planned collar location and orientation, coordinates are MGA Zone 51. See Appendix 1.2 for additional details.
