ASX Announcement 27 July 2021
Multiple Gold Targets Identified At Kaiwalagal
Highlights
-
♦ AQX has received high quality data produced from a closely spaced (50m) airborne magnetic and radiometric survey covering Muralug (Prince of Wales), Zuna and Gialug (Friday) islands (“Kaiwalagal Project”)
-
♦ Multiple compelling targets for intrusion-related gold and epithermal gold deposits identified through data set interpretation of large scale, multi-phase granite batholiths and a younger, overlying caldera type structure
-
♦ Several Mt Leyshon (~3.5M oz Au) gold deposit “look-a-like” reverse polarised magnetic anomalies identified
-
♦ Hyperspectral VNIR/SWIR image multimineral analysis indicates a very extensive, 218km[2] hydrothermal alteration zoning pattern with argillic and sericite-carbonate alteration zones targeted for high priority on-the-ground follow-up
-
♦ Follow-up exploration programs are now being considered
Advanced gold and copper explorer, Alice Queen Limited ( ASX: AQX , “ Alice Queen ” or the “ Company ”), is pleased to provide its shareholders and investors the latest results from its airborne geophysical and satellite hyperspectral surveys recently flown across the Kaiwalagal Project, adjacent to the Company’s Horn Island Project in the Torres Strait, Queensland.
The surveys produced high resolution data sets which have now been processed and reviewed by industry leading independent specialist consultants. Alice Queen is very encouraged by the results from these surveys, which provide strong evidence for the presence of a large-scale hydrothermal system which may drive significant gold mineralisation at Kaiwalagal.
These surveys were completed and funded as part of the St Barbara Limited (ASX:SBM) Joint Venture. Alice Queen has regained ownership of both the Horn Island and Kaiwalagal Projects, following St Barbara’s withdrawal. The Company considers this strategically positive in light of a potential future mining operation on Horn Island and any future discoveries being made within the wider project region.
Alice Queen’s Managing Director, Andrew Buxton said,
The results in from the airborne surveys flown across our Kaiwalagal Gold Project are incredibly encouraging as they have highlighted multiple compelling new targets for intrusions related gold and epithermal gold deposits. This is a huge result in our “ continuing Torres Strait exploration where we continue to seek additional ounces to our flagship Horn Island Resource. Kaiwalagal’s location, immediately adjacent to Horn Island bodes well for Alice Queen as any significant discovery will provide additional ore for any future mining operation established on Horn Island.
Based on these initial positive results, we have made the decision to elevate the prospectively ranking for the Kaiwalagal Project and are currently considering further follow up exploration programs.
Airborne Geophysical & Satellite Survey Results - Kaiwalagal Project
Alice Queen is pleased to report encouraging results from recently completed airborne fixed wing geophysical (magnetic and radiometric) and satellite hyperspectral surveys across the Kaiwalagal project area in the Torres Strait islands. These exploration results represent a significant opportunity as the Company explores for additional gold mineralised systems beyond its flagship ~0.5M oz (inferred) gold resource at the adjacent Horn Island project.
The aim of the Kaiwalagal exploration surveys was to recognise the occurrence of regional hydrothermal systems across the project area and their potential for hosting large scale gold mineralisation. Based on the initial positive results, Alice Queen has elevated the prospectively ranking for the Kaiwalagal project.
The Company engaged Thomson Aviation to complete a fixed wing airborne magnetic and radiometric survey using similar instrumentation and flight parameters to the previous survey completed across Horn Island (see ASX release 17 October 2018). To facilitate data levelling and merging with the existing Horn Island survey, approximately 1km of overlapping data with the recent Kaiwalagal survey was collected (see Figure 1).
The survey comprised low altitude (35m) closely spaced (50m) survey lines bearing NW-SE for a total of 6,829 survey line kilometres, which covered Muralug, Zuna and Gialug Islands. Survey specifications are presented in Table 1.

Magnetic and Radiometric Survey Results and Preliminary Interpretation
The Thompson survey produced exceptional quality high resolution magnetic and radiometric data, which was reprocessed and interpreted by independent geophysical consultants Resource Potentials.
Two broad granitic batholiths have been identified extending from Horn Island across Muralug. These oval-shaped batholith complexes have multiphase intrusive centres that have either positive or negative magnetisation, and likely formed the deep magma chambers below a caldera system in the Carboniferous to Permian periods in geological time. The caldera system has since been eroded to expose granite bodies surrounding by volcanic ignimbrite deposits on the sides (see Figure 2).
The SE side of Muralug and the south side of Zuna Island are intruded by a younger intrusive phase, with distinctive reverse magnetisation. Several discrete and circular reverse magnetic anomalies have been identified and are interpreted to represent younger porphyry plugs or potential breccia pipes. The remanent magnetisation may be associated with hydrothermal alteration halos, similar to the biotitemagnetite alteration and related magnetic anomaly low surrounding the ~3.5M oz Au Mt Leyshon gold breccia pipe (for example see Figure 3). The circular magnetic lows in the SE part of the project area are considered areas of immediate interest for field checking.
==> picture [490 x 354] intentionally omitted <==
Figure 2. Magnetic anomaly image generated from merged detailed and regional airborne survey data sets, highlighting granitic intrusion centres with positive and reversed magnetic anomaly expressions. The reversely magnetised anomalies are interpreted as late stage porphyry plugs or breccia pipes, which may have similarities to the 3.5Moz Au Mt Leyshon breccia pipe gold deposit in Nth QLD to the south.

Ore Controls in the Mt Leyshon Breccia Pipe. Presentation at Intrusion-Related Gold Systems in north Queensland GSQ project meeting December 2017).
Furthermore, the magnetic anomaly pattern across Muralug outlines a number of discrete domains within the larger oval shaped batholith complex, and these domains likely represent different fractionated zones of granitic stocks from an evolving parental magma. Recognising this characteristic early in the exploration history is very positive, as these magmatic zoning conditions are important for the formation of gold prospects, such as the~0.5Moz gold deposit at Horn Island.
WorldView-3 Satellite Hyperspectral Survey Results and Interpretation
Acquisition of WorldView-3 imagery (WV3) covering Visible Near Infrared (VNIR) and Shortwave Infrared (SWIR) wavelength bands (8 in both VNIR and SWIR) was commissioned from Geoimage. The mineral maps were further processed by independent expert Dr Mike Hussey to produce threshold mineral probability maps covering both the Muralug and Zuna Islands.
These mineral maps reveal the mineral associations typically indicative of hydrothermal alteration associated with ore deposits.
==> picture [477 x 344] intentionally omitted <==
Figure 4. Multimineral map interpretation highlights clear pattern of a large scale hydrothermal alteration footprint across Muralug and Zuna Islands. Areas of argillic alteration likely represent the core of a zoning pattern grading out to sericite alteration.
Encouraging results are observed from the WV3 multimineral map outlining a very extensive, hydrothermal footprint of approximately 218km[2] with clear patterns in the distribution of alteration minerals across Muralug and Zuna Islands (Figure 4). This includes a core area of advanced argillic alteration which is surrounded by sericite which then grades into calc-sericites (calcitic and dolomitic). There is also a N-S zone of chlorite crossing the western third of the island.
In other regions of North Queensland, these alteration assemblages are often associated with multimillion ounce economic mineralisation.
Next Steps
Further field programs are now being considered that may include geological mapping and sampling programs to assess these exciting target areas.
Kaiwalagal Project
The Kaiwalagal project covers four islands in the Torres Strait, Queensland. Muralug (Prince of Wales Island) is the largest island in the group covering ~252km[2] . All of the islands within the project area have historical evidence of artisanal mining.

However, the mosaics combining the east and west atmospherically corrected images were not supplied by GeoImage. GeoImage did not carry out thresholding of the 10 mineral maps though they included shapefiles for Alunite, Kaolinite and Illite thresholded above 99% (top 1%). oGeoimage data were supplied to Mineral Spectra Mapping to produce imagery customised for mineral map evaluation. This processing oconsisted of two stages: 1. Original Processing: Consisting of thresholding the 10 grayscale mineral images and then producing them as pseudocolour, colour coded multimineral, ternary red-green-blue mineral composite and shapefiles. 2. Upgraded Processing: Examination of the mineral spectra within the muscovite, illite and dolomite units to determine other minerals present viz sericite, montmorillonite, illite, chlorite, alunite-kaolinite mixtures (argillic alteration) and sericite carbonate mixtures (sericite calcite and sericite dolomite). These mineral units were thresholded and used to produce the same mineral map products produced in the original processing oAll mineral identifications are made by comparison with spectral reference libraries, however field examination and field spectra from these mapped units may revise this mineral naming but the boundaries of the units should be valid. |

The original processing consisted of thresholding each of the mineral maps | |||
| produced by GeoImage (Spectral Suite 02Nov2020) at thresholds of 75%-90% | ||||
| and 90% to 96%, which were compared to each other. From this comparison it | ||||
| was determined, by comparing the pixel spectra within the mapped units, that | ||||
| the 90%-96% threshold level was providing the most consistent mineral | ||||
| delineation and that the Alun-Kaol-Illite and Carbonate Index were not | ||||
| discriminating unique minerals. Masks were then created to eliminate cloud | ||||
| cover in the mineral map products. This proved to be time consuming as the | ||||
| cloud index shapefiles (supplied by GeoImage), which can be used to produce | ||||
| cloud masks in ENVI, were not matching for the West and East image blocks. | ||||
| To produce the optimum cloud mask required producing a mosaic of the | ||||

o hole length. |
| 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. • No drilling or sampling activities undertaken and or reported, this section is not applicable |
|
| Data aggregation methods |
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. • No drilling or sampling activities undertaken and or reported, this section is not applicable |
| 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. • No drilling or sampling activities undertaken and or reported, this section is not applicable |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. • No drilling or sampling activities undertaken and or reported, this section is not applicable |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. • No drilling or sampling activities undertaken and or reported, this section is not applicable |

| Relationship between mineralisation widths and intercept lengths Continues… |
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • No drilling or sampling activities undertaken and or reported, this section is not applicable |
| 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’). • No drilling or sampling activities undertaken and or reported, this section is not applicable |
|
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts 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. • Refer to report for all relevant maps, diagrams and tables |
| 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. • All relevant information of recent work conducted by Alice Queen Limited across the Kaiwalagal project is presented in this report. |
