onlyFINAL IP RESULTS REVEAL MULTIPLE DRILL READY TARGET ZONES AT HORN ISLAND
useAdvanced gold and copper explorer, Alice Queen Limited (ASX:AQX) ("Alice Queen" or the
"Company") is pleased to provide the final results from the processing of its completed Dipole Dipole Induced Polarisation (DDIP) survey carried out at the Company's Horn Island Gold Project, located in the Torres Strait, Queensland.
Highlights
personal | ♦ Final merged data identifies multiple IP chargeability and resistivity target areas | ||||||
♦ | Horn Island is drill ready | ||||||
♦ | Increasing potential demonstrated for Horn Island to host multiple deposits | ||||||
♦ IP chargeability high gradient, interpreted as mapping the hydrothermal system, which may | |||||||
drive gold mineralisation | |||||||
♦ The existing mineral resource area is defined by a chargeability high gradient and associated | |||||||
resistivity low that is a key targeting tool | |||||||
♦ Three broad IP target areas all associated with coincident surface gold or IRG pathfinder | |||||||
enrichment: | |||||||
Jedha 1 (189 ha) | |||||||
Endor 1 (15 ha) | |||||||
Tatooine 1 (101 ha) | |||||||
♦ Construction of the first drill pad to test the broad Jedha 1 target zone is underway | |||||||
Exploration Manager, Adrian Hell said, | |||||||
In 2016, the Company's exploration team and I first commenced mapping and rock | |||||||
chip sampling programs across Horn Island. We have continued this body of work | |||||||
with panning, rock chip and channel sampling. In 2018, we completed an aeromag | |||||||
For" | program and successful shallow drill program at the Southern Silicified Ridge and | ||||||
since that time, further sampling and IP surveys have been completed. This vast | |||||||
body of work has fed into various studies, such as metal zonation, and have allowed | |||||||
us to develop a geological model that suggests a large Intrusion Related Gold | |||||||
" | |||||||
System is present at Horn Island. These broad target zones at Horn Island present a | |||||||
real and exciting opportunity for discovery. | |||||||

Final results from the Dipole Dipole Induced Polarisation Survey (DDIP)
The recently completed IP survey area covered a total distance of 64 line-kms over 13 km2. The data Forf om both this DDIP survey and previous DDIP survey (see ASX release 20 April 2020) has now been merged, with the final processing of the merged DDIP survey data resulting in the identification of
multiple broad target areas.
The total DDIP survey area (merged) now stands at 16km2 for assessment and enables Alice Queen to identify other potential deeper target areas around the current mineral resource area and extending 3.5kms south to the Southern Silicified Ridge (SSR) prospect.
*The Mineral Resource Estimate (JORC 2012, Indicated and Inferred) is reported at a > 0.4g/t Au cut off for 16.7Mt at 0.98g/t Au for a total of 524,000 ounces Au (see ASX release 11 November 2021, HORN ISLAND SCOPING STUDY AND MRE).

Three large scale IP target areas (see Figure 1) have been identified;
- Jedha 1 anomaly
- Tatooine 1 anomaly
- Endor 1 anomalies
onlyA drill program has been designed that is iterative in nature, each drill hole will inform the geological
model and successive holes. Preparation of the first drill pad is underway and drilling remains on track to commence shortly.
Alice Queen's strategy remains focused on making new discoveries at Horn Island in 2022.
Jedha 1 Anomaly (SSR Prospect)
use | ♦ Characterised by high chargeability gradient and associated structurally controlled resistivity | |
low | ||
♦ Target area trends for greater than 5kms covering a projected surface area of 188.5ha | ||
remaining open to the NW | ||
personal | ♦ Displays a similar chargeability response to the Horn Island gold resource area but is | |
significantly larger in scale | ||
♦ | Jedha 1 anomaly deepens and significantly widens in a northerly direction as it extends SE | |
and has a northward trend of ~1.7kms towards the Horn Island gold resource | ||
♦ Correlates with an extensive sericite altered and veined stockwork zone with an approximate | ||
strike length of > 3.5 km that displays a consistent trend with the underlying chargeability | ||
high/resistivity low anomaly | ||
♦ Surface vein chip sampling (see Figures 1 & 2) above this anomaly reveals numerous high- | ||
grade gold assays of >5 g/t Au including: | ||
♦ 250.0 g/t, 50.5g/t, 19.6g/t, 18.2g/t, 17.5 g/t, 15.7g/t, 15.4g/t, 15.4 g/t, 13.2g/t, 11.9 | ||
g/t, 11.5 g/t, 10.4 g/t, 8.8 g/t, 8.4 g/t, 8.3 g/t, 7.9 g/t, 7.9 g/t, 7.8 g/t 6.5 g/t, 6.3 | ||
g/t, 5.9 g/t, & 5.2 g/t Au (see Figure 1 & 2) and channels samples including: | ||
4 m @ 4.20g/t Au incl.1 m @ 11.90 g/t Au | ||
4 m @ 1.89g/t Au incl. 1.0 m @ 4.08 g/t | ||
1.5 m @ 6.18 g/t Au incl. 0.5m @ 15.35 g/t and; | ||
For | 1 m @ 8.79 g/t Au | |
♦ Previous IRG metal zonation studies carried out by Alice Queen of surface soil and rock chip |
samples indicate an Au-Sb enrichment pattern, suggesting a more-distal relationship to the source intrusion, this may be the key driver for gold. The potential for higher-gradegold to develop at depth and/or along strike remains a strong possibility. (see Figure 2).
♦ Previous 9 hole shallow diamond drilling across a limited area above the Jedha-1 chargeability anomaly returned multiple gold assay intercepts >0.5 g/t Au (see Figure 3), the best intercept being 11m @ 2.9g/t Au from 78.8m including 1m @ 16.3g/t Au from 78.8m
♦ Previous pan concentrate sampling reveals multiple occurrences of high concentrations of coarse gold with a subtle size distribution increase towards the SE (see Figure 1). High percentage of these gold nuggets and gold grains are angular and have quartz crystals attached indicating they are derived or sourced from the immediate area.

personal | Tatooine 1 Anomaly |
♦ Originally identified from previous IP survey (refer to ASX release 20 April 2020) reprocessing | |
of the merged data has provided further definition of this prospective target area | |
♦ Characterised by high chargeability gradient with areas of interest concentrated along the | |
associated resistivity low trend | |
♦ Anomaly displays coincidental surface gold and projected IRG pathfinder enrichment patterns | |
♦ The Horn Island gold resource of ~.052M oz is hosted within this anomaly area that extends | |
along a NW-N trend for approximately 1.6kms | |
♦ South ward deepening plunge extending ~300m from the resource boundary | |
♦ Preliminary & broad spaced drilling to test a small part of this anomaly, outside the existing | |
resource envelope, returned positive gold assay intercept (see ASX release 30 June 2021, | |
For | "Drilling Confirms New Broad Gold Zone at Horn Island) including: |
♦ 5m @ 4.4 g/t Au from 128m (20NGD097) incl. 1m @ 12.3gt Au from 128m | |
♦ 1m @ 10.3 g/t Au from 138m (20NGDC098) | |
♦ 1m @ 11.3 g/t Au from 164m (20NGR098) | |
♦ 1m @ 12.4g/t Au from 244m (20NGD105) | |
♦ 2m @ 3.9 g/t Au from 355m (20NGD105) incl. 1m @ 5.4 g/t Au from 355m | |
♦ Potential for higher grade gold lodes as extensions from the Horn Island resource exist |

Endor 1 Anomaly
- Newly defined chargeability anomaly with a strike length of 600m, covering a surface expression of 15ha
- This is a near surface high chargeability anomaly with a target depth to 150m
- A high to lower chargeability gradient trend suggests potential deeper linkages between the resource area and Jedha 1 anomaly
- Forms along a NW trending fault and interpreted vein cluster structures similar with the Horn Island gold resource area and Jedha 1 anomaly
