Minos is the first of several highly prospective targets within IDA’s portfolio to be drill tested as part of a large-scale exploration programme
Indiana Resources Limited ( ASX: IDA ) ( ‘Indiana’ or the ‘Company’ ) is pleased to announce exceptional results have been received from assaying of the first five Reverse Circulation (RC) drill holes recently completed at the Minos Prospect located within Indiana’s 100% owned 5,090 km[2] Central Gawler Craton Gold Project in South Australia (Figures 1 & 2).
A total of 1,604m of RC drilling was completed for 10 holes varying in depth from 72m to 210m. The programme was designed to test a 600m long section in the core of the Minos target. Nine of the ten holes drilled for the programme ended in the mineralised shear zone and the Minos prospect appears to be open along strike and at depth.
Assay results have now been received for five of the ten holes, with the remaining assay results expected within one week. These results confirm and enhance intersections of significant mineralisation in adjacent RC drill holes on Section 600 (Figures 4 and 5).

Company Comment
Indiana’s Executive Chairman Bronwyn Barnes said:
“ These are truly exciting results from Indiana’s maiden drilling programme at Minos and highlight the exceptional prospectivity of the region.
It is clear that our targeting work has been successful, and this initial drilling programme suggests that the Minos Prospect remains open along strike and at depth, so planning for follow-up RC and diamond drilling is underway. We look forward to receiving the balance of assays shortly that will further enhance our understanding of the nature and distribution of the gold mineralisation at Minos.
Having recently completed a placement and a successful share purchase plan, the Company is adequately funded to complete our near-term exploration programmes, as well as expand our targeting activities for other advanced targets within our extensive land package. Once we have reviewed these results, we will provide an update on planned exploration activities for the region.”
Discussion of Assay Results
The Minos prospect, located within the Lake Labyrinth Shear Zone (“ LLSZ ”), is interpreted to be a 30km long WNW- ESE trending regional structure that is at least 50 to 100 metres wide. Minos and Ariadne are located within the central part of the structure whilst Partridge and North Hicks are located at the WNW and ESE extensions respectively (Figure 2). There is no outcrop or workings at Minos and the entire area is covered by at least 1 to 2 metres of soil and calcrete. The only surface expression of mineralisation within the main LLSZ near Minos, is at Ariadne.
Historic detailed mapping at Ariadne that includes structural and/or vein measurements consistently notes predominantly east-west striking mineralised shear structures associated with old workings that dip to the north at 75 to 85 degrees located within the LLSZ where foliation is recorded as sub vertical and parallel to the LLSZ regional trend.
In advance of drilling at Minos, a site inspection was completed at the main workings of Ariadne (located about 50 to 70 metres south of a quartzite/chert marker horizon contact) including a significant stope that has broken through to the surface. This inspection confirmed a stoped structure dipping to the north at around 75 to 85 degrees that strikes east-west at a low angle to the regional LLSZ trend. The equivalent structural position is further south at Minos and appears untested or poorly tested by historic drilling.
Review of core photos at the core library at Tonsley, South Australia, clearly showed north dipping structures running down the core axis of the historic holes drilled at 60 degrees to the NE as well as the regional sub vertical foliation (Figures 7 and 8). Further detailed structural logging of this core is necessary to further determine the structural orientations in the core.
The mineralisation at Minos and Ariadne are not veins but mineralised shear structures with potentially varying orientations located within the regional LLSZ. Based on the above observations the drill programme was devised to intersect and drill across both the sub vertical LLSZ and the north dipping structures by drilling to the south west as earlier drilling may have drilled parallel to some of the interpreted north dipping structures. Earlier RC programmes were 100m spaced reconnaissance traverses and assumed a south dipping structure.

Nine out of the ten holes of the current programme have ended inside the mineralised (sericite-silica-pyrite altered) regional shear zone and can all potentially be extended, if required, to test for repetitions of the internal shear structures at depth. As stated above there may be equivalents of the Ariadne stoped structure further south across the LLSZ. The holes completed have clearly drilled in and out of the internal mineralised shear structures and have also potentially intersected a number of discrete high-grade structures that, given the limited drilling so far, correlate with high grades in adjacent holes that suggest a north or northeast dip. The strike of these structures is unknown and oriented diamond drilling will be required to obtain detailed structural information.
Assay results received from the first 5 holes (LLRC020 – 024) of the recent Minos RC drilling programme are summarised in Table 1. These holes were completed on the 400, 500 and 600 Section lines (Figures 3 to 6) and designed to test mineralisation on existing traverses where historic drilling had intersected significant mineralisation including:
12m @ 10.36 g/t Au from 120m 24m @ 2.18 g/t Au from 44m 6m @ 12.37 g/t Au from 136m 12.5m @ 2.12 g/t Au from 150m 14m @1.51 g/t Au from 86m 5m @ 7.32 g/t Au from 105m 10m @ 4.64 g/t Au from 130m
400 Section
LLRC020 was completed on the 400 Section line (Figures 3 and 4) and intersected significant widths of high grade mineralisation including:
-
19m @ 2.88 g/t Au from 78m
-
5m @ 24.35 g/t Au from 106m
-
22m @ 3.07 g/t Au from 125m
-
3m @ 18.33 g/t Au from 189m
These excellent results confirm mineralisation in adjacent historic drilling, identify discrete high grade structures within the main shear zone and confirm the presence of mineralised structures to at least 170 metres below surface. In addition, LLRC020 ended in the mineralised shear zone at 210 metres and is available for future extension with a diamond tail, as are all RC holes completed in this programme.
500 Section
LLRC023 and LLRC024 were completed on the 500 Section line (Figures 3 and 5) and intersected significant mineralisation including:
-
4m @ 1.27 g/t Au from 101m
-
8m @ 1.38 g/t Au from 128m
-
18m @ 1.11 g/t Au from 141m and,
-
12m @ 1.80 g/t Au from 79m
These holes were drilled to infill a gap in the existing drill fence (LLRC023) and test for mineralisation associated with interpreted NE dipping internal structures within the shear zone (LLRC024).

==> picture [594 x 75] intentionally omitted <==
600 Section
LLRC021 and LLRC022 were completed on the 600 Section line (Figures 3 and 6) and intersected significant mineralisation including:
-
2m @ 5.51 g/t Au from 107m
-
8m @ 4.79 g/t Au from 89m
-
28m @ 1.45 g/t Au from 101m
-
5m @ 1.21 g/t Au from 189m
LLRC021 was designed to test for high grade internal structures on the SW edge of the shear zone and intersected 2m @5.51g/t Au from 107m indicating the SW interpreted shear zone boundary may still be open. LLRC022 successfully confirmed high grade mineralisation on the NE side of the shear zone.
– Planned Programme Next Steps
Indiana is planning to comprehensively review these results, along with results expected within the week, which will form the basis of future planned exploration activity. This plan may include a mix of RC drilling at known prospects within Indiana’s Central Gawler Craton landholding, including Ariadne, Company Well, North Hicks and Partridge, to expand the current zones of mineralisation.
Previous significant drilling intercepts from regional targets include:
-
Ariadne – 6m @ 4.05 g/t Au, 11m @ 2.44 g/t Au, 12m @ 1.18 g/t Au
-
Earea Dam – 4m @ 10.2 g/t Au, 3m @ 13.8 g/t Au Boomerang – 4m @ 5.44 g/t Au, 2.0m @ 10.5 g/t Au Double Dutch – 34m @ 1.18 g/t Au, 18m @ 1.07 g/t Au, 25m @ 1.25 g/t Au
Reconnaissance auger-drilling-assisted calcrete sampling is also being considered along the LLSZ to outline potential additional zones of mineralisation within areas where surface sampling may not be suitable due to the shallow soil cover. The Company is currently reviewing historical exploration at Earea Dam, Double Dutch and Boomerang with a view to planning further exploration activity in the coming months.

Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | **Commentary ** |
|---|---|---|
| Sampling **techniques ** |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• All historic data was supplied by Patron Resources. Additional data has been downloaded from the South Australian Mines Department SARIG server and is publicly available • Operators: • IDA - Indiana Resources Limited (LLRC series) • MIM - MIM Exploration (CW and LL series) • Grenfell Resources (BG series) • Tarcoola Gold (EDR and EDC series) • ECG - Endeavour Copper Gold (TARC, THRC and THDD series) • Geochemical Data Calcrete assays downloaded from South Australian Mines Department SARIG server (publicly available), various companies and assay methods • IDA RC Drilling, LLRC series (this report) • RC Drilling undertaken at the Minos prospect in January 2021 • Drilling contractor was Bullion Drilling based in Port Augusta S.A. • Rig type was a Schramm T450WS with a 700+psi compressor, bit size 140mm • Samples were collected at 1m intervals from an automatic splitter, average sample weight was ~2kg • Samples analysed for Au by Bureau Veritas in Adelaide using laboratory method FA001, 40g Fire assay AAS • ECG Drilling (Minos, Ariadne and Double Dutch prospects) • Early ECG regional reconnaissance slimline AC/RC drilling (2013) was conducted with a small rig with no onboard splitter – Composite (4m) assay samples were collected via scoop from sample piles, with subsequent 1m samples (identified from anomalous composite samples) also collected via scoop • Later (2014 onwards) ECG RC drilling with a larger rig collected a bulk sample and a smaller sample for analysis (2-3kgs) via an onboard splitter for each metre with sample split to around 1/8th. Composite (4m) assay samples were initially collected via scoop from bagged samples; with later analysis of selected 1m samples following assessment of anomalous composite results • In 2015 diamond drilling generated NQ2 and HQ triple tube (HQ3) sized core. NQ2 core was sampled as half core, and HQ3 core was sampled as either half or quarter core after being cut using a diamond saw. Drill core sample intervals ranged from 0.4- 1.25m, with smaller interval for selected geological units • Samples analysed for gold ± multi elements by Australian commercial laboratories (industry standard) |

| **Geology ** | • Deposit type, geological setting and style of mineralisation. | • Lake Labyrinth Shera Zone (LLSZ), Minos and Ariadne The gold mineralisation intersected in drilling to date is concentrated within an intense alteration system (primarily sericite, chlorite, pyrite) of up to 100 metres wide. The majority of the LLSZ is under a thin (2 to 20 metre) veneer of transported cover rendering conventional surface geochemical exploration largely ineffective over the majority of the shear zone • Earea Dam Gold was discovered in outcrop along a NE-SW oriented outcropping shear within Archean-age Kenalla gneiss which is locally intruded by Kimban-age (Proterozoic) mafic dykes and rhyolite/rhyodacite dykes associated with the Gawler Range Volcanics • Other prospects To be assessed, not understood at the time of reporting |
| Drill hole **Information ** |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• Refer to the body of text of this report for information material to the understanding of the exploration results • No known significant material information excluded from this report. Drilling which has not intersected significant mineralisation is included in Figures but not included in Significant Au Intercepts tables |
| Data aggregation **methods ** |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Drilling Results reported are highlights only for each prospect, typically 1m > 0.5 ppm Au. No top cutting applied to any reported result • Results were downhole composited for grades above 0.5 ppm Au allowing for 2m of internal dilution • No metal equivalents have been reported |
| Relationship between mineralisation widths and **intercept lengths ** |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true _width not known’). _ |
• Reported intersections are downhole lengths – true widths are unknown at this stage • Drilling generally considered perpendicular to the target • Refer above |
| **Diagrams ** | • Appropriate maps and sections(with scales) and tabulations of intercepts | • See figures and tables in this report |
| should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |

| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• See figures and tables in this report |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• The Company continues to conduct reviews on historic exploration data from a variety of sources for meaningful exploration results and will report them in separate releases as significant detail comes to hand |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
