Company has been successful in its Co-funding grants for exploration in the Northern Territory
Inca Minerals Limited (ASX: ICG) ( Inca or the Company ) is pleased to advise that assay results from recent rock chip sampling at the newly-granted Jean Elson Project, located 450km north-east of Alice Springs in the Northern Territory, have returned highgrade gold and copper results, highlighting outstanding prospectivity for new Iron Oxide-Copper-Gold (IOCG) discoveries.
Assay results have been received for 45 rock chip samples collected during a recent mapping and sampling program that targeted the two main prospect areas within the Jean Elson Project – the Mt Cornish South and Camel Creek prospects (see ASX Announcement dated 3 May 2021).
Seven rock chip samples were collected from Mt Cornish South and 38 from the general area of Camel Creek (Figures 1-4 and Appendix 1). Project location is shown in Figure App 1-01 (Appendix 2).
Assay results have significantly strengthened the project’s prospectivity, returning the first signficant gold mineralisation delivered from the Jean Elson Project to date, in addition to strong copper (Cu) and elevated silver ( Ag ) and bismuth ( Bi ). Sample JE0097 returned 3.21g/t Au + 1.89% Cu + 0.28% Bi (image right), with the nearby JE0094 also returning an encouraging result of 0.36g/t Au + 1.42% Cu + 957ppm Bi .
These samples, together with assays from JE0096 ( 1.28% Cu ), form the newly discovered extension of the V2 vein and lie 2540m NE of the previously-reported KV vein (Figure 1). Mineralisation at V2 comprises three sub-cropping quartz-iron ( Qtz-Fe ) veins over a 16m-wide zone, with Cu enrichment noted to extend beyond the veins and into the altered granite host rock.

Additional new mineralisation and structures sampled nearby include:
-
the 2m-wide RV Qtz-Fe vein (an extension of the previously reported V1 vein), that occurs within a 20m wide zone with other 0.3-1.0m wide vein/veinlet zones (JE0090-JE0093; low Cu reported)
-
a 75m NW strike extension to J-Vein with 1.27% Cu (JE0098; in situ) that extends J-Vein to over 150m length
-
Additional float material with up to 0.68% Cu that may indicate further extension to J-Vein (JE0099) and potential for an additional structure (JE0100-JE0101)
Additional Cu-dominant mineralisation was also sampled in new occurrences further downstream of Camel Creek and includes new zones at:
-
100m downstream – 0.46% Cu in brecciated granite with disseminated malachite after chalcopyrite (JE0103)
-
350m downstream – a 70m wide zone with intermittent host rock brecciation and veining (JE0104-JE0108) that includes strong results of 9.65% Cu (JE0107; float), 0.19% Cu (JE0105) and 0.16% Cu (JE0108) sampled from areas of stronger alteration and veining
-
850m downstream – 0.19% Cu in minor quartz veined granite
While geological observation is limited by the sub-crop nature of lithologies within Camel Creek – and masked by thin but persistent sand cover away from the creek – in situ Cu enriched structures are now known to occur over a 1.25km wide zone. The strike extent of this mineralisation remains unknown; however, the veined-stockworked-brecciated Sunset Boulevarde Cu occurrence 1.1km SE of Ningaloo and observation of minor Qtz-Fe veining (JE0112-JE013; up to 75ppm Cu) 1.6km to the NW suggest that the Ningaloo system at Camel Creek is several kilometres in scale.
Higher-grade mineralisation is spatially restricted to veins that occur up to 5m wide, with additional mineralisation noted in zones of stronger host rock brecciation and, in places, Cu enrichment extending into the host rock granites. Felsic granite host rocks show hydrothermal bleaching with chlorite-sericite alteration stronger in the upstream portion of Ningaloo and epidotechlorite more dominant in the downstream portion. Pods of poorly outcropping mafic bodies also occur.

Importance of Results and Next Steps
In addition to increasing the known extent of mineralisation and alteration at the Jean Elson Project, recent reconnaissance by Inca has resulted in a better understanding of the hydrothermal systems indicated at both Camel Creek and Mount Cornish South.
At both prospects, a definite paragenesis is observed that indicates evolution of hydrothermal fluids over time from reduced, silica ( Si ) rich (early stage), transitioning through reduced-oxidised Si-Fe rich (middle stages), to late-stage oxidised, Femanganese ( Mn ) rich fluids. This sequence is illustrated in Figure 5 with rock chips from Mount Cornish South, where early stage quartz rich material is progressively overprinted/brecciated by increasing Fe rich fluids.
Changing redox conditions of fluids are indicated by initial Fe phases occurring as euhedral magnetite (later fully altered to haematite pseudomorphs), with latter primary Fe oxides forming as platy haematite, prior to widespread, low pressure Fe-Mn flooding. Secondary haematite and goethite occur as weathering products of Fe oxide and sulfide phases.
Such a fluid paragenesis is a feature described in the generic IOCG model and results from the mixing of magmatic/ metamorphic waters (hot, reduced, metal bearing) with surface waters (cold, oxidised) that can be a primary cause for metal precipitation leading to ore deposit formation. That this relationship is observed at two large prospects is considered by the Company to strengthen IOCG prospectivity of Jean Elson.

Figure 5 A simplified illustration of vein paragenesis at Mount Cornish South that shows early stage, Si rich, reduced fluids phasing towards later stage, Fe-(Mn) rich, oxidised fluids; base metal enrichment appears strongest in the intermediate stages with an interpreted drop in system pressure with time; Fe is a major component with octahedral magnetite (early stage, fully overprinted), specular-platy haematite (intermediate stages), and fine grained/massive haematite-goethite (late stage flooding); weathering and hydration to goethite is variable depending on rock type.
The discovery of significant Au grades in rock chips is also a notable achievement for the Jean Elson Project given that the East Arunta Block historically records Cu dominant mineralisation (Figure 6). Identification of Au, alongside strong enrichment of Cu-Fe and elevated Ag-Bi, is an exciting development early within the Project’s timeline and this is further heightened by the limited outcrop available to sample.
Inca’s East Arunta Group – including the Jean Elson, Lorna May and Hay River Projects – lies within an underexplored but highly prospective geological setting in proximity to the craton margin between the North Australian Craton and Arunta Block.
In order to systematically advance the Jean Elson Project forward, Inca has scheduled a c. 30,000 line km AMAGRAD survey to commence in September (note timing related to pastoral mustering activities). Results of this survey will be used to refine targets to determine requirements for follow up exploration. Given the widespread but thin sand cover lying over much of the Project area, it is considered likely that future exploration may identify additional areas of interest.

The East Arunta Block – hosting the Jean Elson, Lorna May and Hay River Projects – is an underexplored terrane dominated by the Jervois Cu field with the region reporting limited Au enrichment by past explorers. Inca’s projects in this area fall with a prospective setting along the interpreted craton margin between the North Australian Craton and the Arunta Block.

The following information is provided to comply with the JORC Code (2012) exploration reporting requirements.
SECTION 1 SAMPLING TECHNIQUES AND DATA
Criteria: Sampling techniques
JORC CODE Explanation
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or hand-held XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
Company Commentary
This announcement refers to reconnaissance mapping and sampling field work conducted at the Jean Elson Project. Forty-five rock chip samples were taken. Rock samples were collected that were considered representative of the source material and were recorded as either in situ or float material. This announcement also refers to exploration results conducted by Inca and by previous parties and recorded in the Northern Territory Mines Department databank, assessed and reviewed by the Company. Strong correlation is seen between the Company’s assay results as those of previous explorers.
JORC CODE Explanation
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.

Strong correlation is seen between the Company’s assay results as those of previous explorers.
JORC CODE Explanation
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 (e.g. ‘reverse circulation drilling was used to obtain 1m samples from which 3 kg was pulverised to produce a 30g charge for fire assay’). In other cases, more explanation may be required, such as where there is a coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
Company Commentary
Mineralisation is evidenced in the field by visible copper minerals and intensity of alteration and veining. The samples taken from mineralised outcrop are considered representative of such mineralisation and hydrothermal alteration outcropping at the various locations mapped and sampled. Approximately 2kg of sample was taken from each sample location. Where in situ material could not be sampled, a limited number of float samples were collected and duly recorded. Several channel samples of select veins were also collected perpendicular to strike for representivity.
Criteria: Drilling techniques
JORC CODE Explanation
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).

==> picture [172 x 48] intentionally omitted <==
Company Commentary
The samples taken from mineralised outcrop are considered representative of such mineralisation and hydrothermal alteration outcropping at the various locations mapped and sampled. Approximately 2kg of sample was taken from each sample location. The historic sample assay results referred to in this announcement were generated by a previous exploration company. The sampling distribution appears controlled by the limit of exposed rock in a dry creek bed. To this extent, the sampling technique appears representative of the limited rock exposure in the creek bed. Additionally, strong correlation between the Company’s assay results and those of previous explorers indicate representative sampling has been achieved. The Company also collected channel samples of several select vein perpendicular to strike to assess the mineralisation style and representivity.
JORC CODE Explanation
Whether sample sizes are appropriate to the grain size of the material being sampled.
Company Commentary
The average rockchip sample size of approximately 2kg is considered appropriate.
Criteria: Quality of assay data and laboratory tests
JORC CODE Explanation
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.

JORC CODE Explanation
Whether sample compositing has been applied.
Company Commentary
Forty-five rock chip samples were taken in the recent field trip to the Jean Elson Project with representative samples collected. Sample compositing was carried out at most locations insofar as multiple samples were collected from a 1m x 1m and 2m x 2m areas made into a single sample. The historic sample assay results referred to in this announcement were generated by a previous exploration company. Sample compositing was undertaken though the extent is unknown. A note: Sample compositing is a common practice in collecting rockchip samples from a single outcrop location. Commonly from an area centred on a target rock, compositing may include the collection of multiple ±100g samples from 10m[2] for a total of 1-3kg samples. The practice increases representativeness of the sample.
Criteria: Orientation of data in relation to geological structure
JORC CODE Explanation
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
Company Commentary
This announcement refers to mapping and sampling field work conducted at the Jean Elson Project. Forty-five rock chip samples were taken which were spaced according to limited and at times confined rock exposure. Best exposure was noted along dry creek beds so there is a bias of information in such geographical places. The historic sample assay results referred to in this announcement were generated by a previous exploration company. Based on coordinates alone, the sampling distribution appears controlled by the limit of exposed rock in a dry creek bed, like that of the Company’s. It this extent, the sampling is unbiased in terms of known mineralisation orientations.
JORC CODE Explanation
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
Company Commentary
N/A – No drilling results, sampling or assay results are referred to in this announcement.
Criteria: Sample security
JORC CODE Explanation
The measures taken to ensure sample security.
Company Commentary
