Potential for Tier-1 scale porphyry/intrusive-related and skarn discoveries at MaCauley Creek greatly enhanced
Inca Minerals Limited (ASX: ICG ) is pleased to advise that it has substantially upgraded the potential of its MaCauley Project, located in northern Queensland, after discovering significant visible skarn-style copper mineralisation in multiple locations during a recent surface mapping and sampling program.
The purpose of the field tip was to investigate recently identified prospect areas in the northern part of the project (Mount Brown, Carraway North and Wallaroo) that were generated from an independent review and remodelling of historical geophysical and geochemical data (as outlined in past ASX announcements, 28 September 2020 and 15 March 2021) and to investigate other new prospect areas identified in the central and southern parts of the project area.
Among other positive results, mapping has identified several mineralised skarn occurrences and a gossanous porphyry (Figure 1). A gossan is the weathered remains of sulphide mineralisation. Accordingly, the Project has been elevated in terms of its potential to host skarn and/or porphyry/intrusive-related mineralisation with the discovery of multiple new and extensive occurrences of visible copper mineralisation reinforcing the opportunity to make a Tier-1 scale copper discovery.

Mt Brown Prospect
The Mt Brown Prospect ( Mt Brown ) is located in the northern part of MaCauley Creek, approximately 5km south-west and along strike from the Mt Moss Fe-skarn mine (Figure 2). It was recognised as a skarn-porphyry target following an independent review of past exploration (ASX announcement 28 September 2021). It hosts a subtle magnetic high anomaly (1.0km x 0.5km) and known copper, gold, silver, molybdenum, lead, and zinc mineralisation, with historic peak values 8.22% Cu , 96ppb Au , 127g/t Ag , 245ppm Mo , 3.60% Pb , and 2.04% Zn .
As a result of the positive review Mt Brown was mapped and sampled by Inca for the first time during the recent field trip. A total of 18 samples were taken (Figure 3). Mapping has resulted in the identification of gossanous quartz porphyry intrusions, chalcopyrite-magnetite skarn mineralisation (Figure 4), and multiple historic small copper and tin mine workings.

Mt Brown is an exceptional prospect that has been materially elevated in exploration potential as a result of the current field trip. Mt Brown hosts gossanous porphyry intrusions, copper-magnetite skarn mineralisation, numerous historic mine workings, a discrete magnetic high anomaly and strong historic sample results. It is along strike from a known skarn deposit. For all these reasons, Mt Brown is considered highly prospective for potentially economic porphyry-skarn mineralisation.
Wallaroo Prospect
The Wallaroo Prospect ( Wallaroo ) is located in the northern part of MaCauley Creek, approximately 5km southeast of the Mt Moss mine (Figure 2). Like Mt Brown, it was recognised as a skarn-porphyry target following an independent review of past exploration (ASX announcement 28 September 2021). It hosts a coherent magnetic high anomaly (1.25km x 0.5km) and known copper, silver, lead, and zinc mineralisation, with historic peak values 5.45% Cu , 132g/t Ag , 0.61% Pb , and 3.72% Zn .
As a result of the positive review Wallaroo was mapped and sampled by Inca for the first time during the recent field trip. Twenty-one samples were taken. Mapping has resulted in the discovery of multiple copper-lead-zinc skarn-like units over a zone 850m in strike length and 250m width, with individual skarn units varying in thickness from 0.5m to 7m (Figure 5). This discovery strongly correlates with the magnetic high anomaly (Figure 5), that likely associates with abundant massive magnetite float observed in parts of the prospect. Mapping recognised the occurrence of metal sulphides, chalcopyrite, sphalerite and galena and strong secondary copper minerals within these poorly sub-cropping, recessive skarn-like units (Figure 6).

Like Mt Brown, Wallaroo is an exceptional prospect that has been materially elevated in exploration potential as a result of the current field trip. Wallaroo hosts copper-lead-zinc skarn mineralisation over an area of 850m x 250m that very closely corresponds to a 1.25km x 0.5km discrete magnetic high anomaly. For these reasons, Wallaroo is considered highly prospective for potentially economic porphyry-skarn mineralisation.
Wallaroo Southwest Prospect
The Wallaroo Southwest Prospect ( Wallaroo SW ) is located in the northern part of MaCauley Creek, approximately 4km southwest and along strike from Wallaroo (Figure 2). Like Wallaroo and Mt Brown, it has a magnetic high anomaly, but unlike these prospect areas, no historic sampling is recorded there.
Six samples were taken by Inca. Mapping has resulted in the identification of a possible bleached quartz-feldspar andesite with rare quartz-sulphide veinlets (Figure 8), epidote altered andesite and a small outcrop of secondary copper (Figure 8). These outcrops correlate with the magnetic high anomaly (Figure 7).

Figure 8 : Sample photos. MC0077 (left) Bleached andesite. MC0080 (right) Malachite-chrysocolla bearing quartz vein mineralisation.
Wallaroo SW may be interpreted as a prospect of equal potential to that of Wallaroo on the basis of it being on the same southwest trend, that is hosts known igneous rocks, and that is hosts a magnetic high of the same tenor as that at Wallaroo. Wallaroo SW is therefore considered prospective for potentially economic porphyry-skarn mineralisation.
Copper Cliffs Prospect (formerly Carraway North Prospect)
The Copper Cliffs Prospect ( Copper Cliffs ) is located in the northern part of MaCauley Creek, approximately 4km east of Mt Brown and 2.5km northwest of Wallaroo SW (Figure 2). It was recognised as a broad, though vaguely defined, porphyry/intrusion-related target following an independent review of past exploration (ASX announcement 28 September 2021). It hosts a subtle low tenor magnetic high anomaly (1.5kmx 1.0km) and known low-level copper, gold, silver, and molybdenum mineralisation.
As a result of the positive review, the prospect [then named Carraway North) was mapped and sampled by Inca for the first time during the recent field trip. Fourteen samples were taken (Figure 9). Mapping resulted in the discovery of an extensive outcrop of weathered quartz-sulphide lode with strong secondary copper mineralisation (malachite and azurite) (Figure 10) over a strike length of 550m and with width varying from 5m to 15m. The quartz-sulphide lode occurs adjacent to an outcrop of weathered, altered microgranite over 70m by 100m that in places hosts quartz/ex-sulphide network veins and secondary malachite bleeds (this occurrence precipitated the change of prospect name; Figure 11). The host material is a coarse- grained granite that is increasingly fractured and veined in proximity to microgranite and lode outcrops.

Figure 11 : Copper Cliffs outcrop (left) showing extensive malachite bleeds and sample MC0085 (right) an altered microgranite with disseminated ex-sulphides (pyrite?) and quartz and ex-sulphide network veins.
With the genuine discovery of the large copper outcrop (Figure 11), Copper Cliffs has become a very important and highly prospective prospect. It hosts a large microgranite-quartz lode complex over 550m in strike length and is considered highly prospective for potentially economic porphyry/intrusion-related mineralisation. Notably, this newly discovered occurrence is larger than the Silver-Prospecting Area that strikes over 300m in the central portion of the Project, as described in ASX announcements dated 19 September 2019, 15 October 2019, and 4 November 2019.

Carraway Hill Prospect – Part of the Brolga Prospect
The Carraway Hill Prospect ( Carraway Hill ) is located in the north-central part of MaCauley Creek, approximately 4km southwest and along strike from Wallaroo SW (Figure 2) and approximately 8km along strike from Wallaroo. It is immediately south of the Carraway North Prospect and forms the northern part of the mega-sized Brolga Prospect (of central MaCauley Creek) (ASX announcement 15 March 2021).
Carraway Hill, a previously unexplored area, was mapped and sampled by Inca for the first time during the recent field trip. Four samples were taken (Figure 12). Mapping resulted in discovery of a fine grained silicified intrusive body with abundant disseminated pyrite and rarer pyrite-bearing veinlets, which is interpreted to potentially represent porphyry-style phyllic alteration. Other visited areas of the prosect were dominated by fresh volcanics with zones of propylitic style alteration.
Field work focused on a 300m by 500m sized magnetic anomaly in the northeast portion of the prospect with the altered pyrite-bearing intrusive strongly correlating with magnetics. As such, Carraway Hill is elevated from a formerly low-ranked prospect and due to it “central” location is considered to provide a nexus between the skarn-porphyry targets to the north and the porphyry targets to the south.
==> picture [362 x 257] intentionally omitted <==
Figure 12 : Carraway Hill sample location plan with total magnetics as plan background. The stippled magnetic anomaly is distinctive with field work focusing on the northeast portion of the prospect where porphyry-style phyllic alteration (?) was observed and sampled. At the time of writing assay results are not available.
Eckleburg West Prospect – Part of the Brolga Prospect
The Eckleburg West Prospect ( Eckleburg West ) is at the northern part of the mega-sized Brolga Prospect (of central MaCauley Creek) (ASX announcement 15 March 2021). It is a located 1.5km west of Eckleburg East (Figure 2).
Field work assessed known magnetic anomalies at Eckleburg West and followed up encouraging propylitic style alteration and copper-lead-silver mineralisation discovered at the prospect by Inca during 2019 (ASX announcement dated 2 October 2019). Sixteen samples were taken during the recent field work (Figure 13), that resulted in the discovery of an additional silicified intrusive body with abundant disseminated pyrite, low levels of chalcopyrite and secondary copper minerals (Figure 14).
The occurrence of metal enriched propylitic alteration and now sulphide-bearing phyllic style alteration correlating to magnetic anomalies at Eckleburg West is highly encouraging and marks the prosect as prospective for porphyry style mineralisation, similar to Carraway Hill. The identification of chalcopyrite, albeit at very low levels, is an additional positive development.

Importance of Results and MaCauley Creek Exploration Model
The results of the recent field trip, the subject of this announcement, have fundamentally changed the prospectivity of MaCauley Creek. MaCauley Creek was already highly prospective for skarn and porphyry/intrusion-related mineralisation. With the discovery of several large occurrences of both forms of mineralisation and associated alteration, coinciding with discrete magnetic high anomalies, MaCauley Creek is justifiably re-rated. It is now considered an exceptional exploration project certainly warranting considerable fast-tracked exploration.
An exploration model can now be proposed with an increased degree of confidence (Figure 15). It is included in this announcement as a visual aid in the juxtaposition of prospects, mineralisation types and hosting geology, though is stylised, schematic diagram not drawn to scale.
==> picture [511 x 238] intentionally omitted <==
Figure 15 : Proposed Exploration Model for MaCauley Creek. Observations from recent field work have increased understanding of regional-local geology, and relationships between mineralisation and alteration styles that will assist - and be tested by - future exploration at the Project (not to scale). The model shows the position of the prospects in relation to the known surface and hypothetical sub-surface geological architecture. INSERTS include a photo of the Mt Moss Mine (not an asset of the Company) as an example of skarn mineralisation in the Perry Creek Formation. The second insert is of a drill section (not undertaken by the Company) at the Silver Prospecting Area that shows known mineralised telescoped granites (granites within granites).
Next Steps
==> picture [138 x 150] intentionally omitted <==
The in-house review of the field trip results will continue whilst rock chip samples are being analysed. Assay results are anticipated to be received in mid to late September.
A detailed AMAGRAD survey covering the northern third and the southeast corner of MaCauley Creek is planned for the coming weeks (Figure 2). This survey, of approximately 3,000-line kilometres, will assist in refining the northern prospects and Mt Podge. The Company advises Covid-19 related travel restrictions may impact upon the exact timing of this survey.
The Company is also reviewing the many recommendations stemming from the thorough field trip report. There is a very high level of confidence that follow-up ground geophysics – principally IP surveying – will be necessary for detailed drill targeting studies, with other possible exploration techniques being assessed including soil sampling, ground magnetic surveying, and prospect scale mapping.
It is Inca’s intention to advance the MaCauley Creek Project prudently and systematically, and the Company looks forward to further exploration leading to high impact drilling campaigns.

As mentioned above, further inhouse reviews will be completed in the following weeks that will focus on the Brolga Prospect located in central MaCauley Creek. This area remains an exception exploration area (Figure 16).

Appendix 3: JORC CODE 2012 Compliance Table
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 exploration conducted by previous holders of mining and exploration rights for areas within the Company’s granted EPM27124 and EPM27163. Exploration results referred to in this announcement pertain to past rockchip sampling (141 samples) and also to past geophysical survey results. The Company cannot confirm the quality of these results. However, the methods deployed by the previous explorers to obtain the sample results are considered “industry standard”.
110 new rock chips samples collected by the Company are included in this announcement, but assay results are not available at the time of writing.
JORC CODE Explanation
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Company Commentary
This announcement refers to exploration conducted by previous holders of mining and exploration rights for areas within the Company’s granted EPM27124 and EPM27163. The Company cannot confirm sample representivity nor whether appropriate calibration of any measurement tools or systems used, however, the reproducibility of exploration results by different explorers is considered by the Company as evidence of the reliable nature of past exploration results. In addition, past exploration assay results as presented in this announcement were analysed by independent laboratories indicating that appropriate calibration of measurement tools were used. Additional detail on assaying parameters are provided in the relevant section(s) below.
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
This announcement refers to exploration conducted by previous holders of mining and exploration rights for areas within the Company’s granted EPM27124 and EPM27163. Whilst the Company cannot confirm the quality of the exploration results data included in this announcement, the methods deployed by the previous explorers and reported in this announcement are considered appropriate for reporting mineralisation. The reproducibility of exploration results by past explorers is considered evidence that acceptable and appropriate sampling and assaying techniques were employed.
New samples by the Company included in this announcement were preferentially sampled from in situ occurrences and, where not possible, from non in situ occurrences such as mine waste dumps and creek float. Representative material was preferenced. At the time of writing, assay results were not available.

Tenement Type: Two granted Queensland Exploration Permit for Minerals (EPM): EPM 27124, EPM27163.
Ownership: EPM 27124/163: Inca (90%) and MRG Resources Pty Ltd (MRG; 10%) under an executed Joint Venture Agreement (JVA). 1.5% NSR payable to MRG.
JORC CODE Explanation
The security of the land tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
Company Commentary
The JVA and tenements are in good standing at the time of writing.
Criteria: Exploration done by other parties
JORC CODE Explanation
Acknowledgement and appraisal of exploration by other parties.
Company Commentary
This announcement refers to exploration conducted by previous parties recorded in Mines Department databanks which was reviewed by MRG.
Criteria: Geology
JORC CODE Explanation
Deposit type, geological setting, and style of mineralisation.
Company Commentary
The geological setting is dominated by well exposed Carboniferous aged granitic rocks that have intruded older Devonian-Carboniferous metamorphic lithologies. Minor sedimentary and volcanic units overlie the prospective granitic rocks in portions of the project area. The project area is prospective for porphyry/intrusion-related and skarn style mineralisation.
Criteria: Drill hole information
JORC CODE Explanation
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:
-
Easting and northing of the drill hole collar
-
Elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar.
-
Dip and azimuth of the hole.
-
Down hole length and interception depth.
-
Hole length.
Company Commentary
This announcement does not refer to drilling or drilling results.
JORC CODE Explanation
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.
Company Commentary
Rockchip sample locations georeferenced to QLD’s grid system GDA94, zone 55.

Criteria: Data aggregation methods
JORC CODE Explanation
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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 shown in detail
Company Commentary
This announcement refers to exploration conducted by previous holders of mining and exploration rights for areas within the Company’s granted EPM27124 and EPM27163. Exploration results referred to in this announcement pertain to past rockchip sampling (141 samples) and also to past geophysical survey results. The Company cannot confirm if maximum and/or minimum grade truncations, or other data averaging techniques were used in the generation of mineralised intervals reported in this announcement.
JORC CODE Explanation
The assumptions used for any reporting of metal equivalent values should be clearly stated.
Company Commentary
No metal equivalents are used in this announcement.
Criteria: Relationship between mineralisation widths and intercept lengths
JORC CODE Explanation
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 (e.g. ‘down hole length, true width not known.’)
Company Commentary
This announcement does not refer to drilling or drilling results.
Criteria: Diagrams
JORC CODE Explanation
Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not limited to a plan view of drill hole collar locations and appropriate sectional views
Company Commentary
Several diagrams are provided that show locations of previous exploration results included in this announcement.
Criteria: Balanced reporting
JORC CODE Explanation
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.
Company Commentary
The Company believes this ASX announcement provides a balanced report of the past exploration results referred to in this announcement.
Criteria: Other substantive exploration data
JORC CODE Explanation
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.
Company Commentary
This announcement refers to six previous ASX announcements, dated 30 July 2019, 19 September 2019, 2 October 2019, 15 October 2019, 4 November 2019, 28 September 2020 and 15 March 2021.
Criteria: Further work
JORC CODE Explanation
The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
