Pacgold to Commence Regional Scale Aircore and RC Programmes at Alice River
HIGHLIGHTS
-
6,000m aircore bedrock geochemical programme scheduled to commence in first week of October
-
Regional focus aimed at unlocking size potential of overall mineralised system and generation of multiple follow up drill targets for the 2025 exploration season
-
Programme to test a comprehensive 14km of IP geophysical and structural targets with maximum coverage possible of known mineralised corridor
-
3,000m reverse circulation (RC) programme designed to following up on existing regional targets Posie, Jerry Dodds, Central Target and Southern Target areas not previously drilled
-
Multiple target areas of known historic mineralisation coinciding with geophysical structural anomalies to be tested over the next quarter
Queensland focused gold explorer, Pacgold Limited (ASX: PGO) (‘ Pacgold ’ or ‘ the Company ’) is pleased to provide an exploration update on the recommencement of a regional aircore and RC drilling campaign at the Company’s 100% owned Alice River Gold Project (‘ the Project’ ), 300km northwest of Cairns, North Queensland.
New Pacgold Managing Director, Matthew Boyes, commented :
“Having spent the last week on a very successful first site visit to Alice River, I came away extremely impressed with the potential for delineation of a regional large scale gold system at Alice River. The majority of the system hasn’t been drill tested, with this new programme designed to better understand and unlock a further 12-14km of previously untested strike extensions.”
“IP geophysical targets, in conjunction with previously drilled RC, diamond and airtrack holes, have defined anomalous gold mineralisation in approximately 90% of all drillholes drilled to date. That’s an extremely high success rate and I feel the project purely lacks ‘drills turning’ on more than one of the multiple structural and geophysical targets identified to date to unlock and define a significant system.”
“Drilling is commencing within the next 3 weeks with a full team now back on site and clearing and pegging of the 800 plus drill sites now nearing completion. I’m looking forward to seeing drills turning and initiating some continuous newsflow into the near year”

Multiple targets to be drill tested over 14km of strike extension
Through integration of the regional IP resistivity study, structural interpretation, mapping, surface sampling and historical data, multiple targets along a structural corridor in excess of 14km in length have been identified for drill testing.
Inflections, offsets and directional changes clearly evident within the IP data and structural mapping are priority targets for the first pass aircore drilling, as these zones sit primarily under very shallow sand alluvial cover and have never been previously tested. These new target zones exhibit all the features of the F1a Zone at the Central Target area through direct correlation of the IP and mapping data, which yielded the first high grade discovery within the Alice River province.

RC drilling will also follow up the encouraging first pass drilling results from the Q4 2023 programme at the Posie, Jerry Dodds and Southern Targets.
Posie and Northern Target areas
Regional exploration completed by Pacgold in the second half of 2023 was very successful in intersecting significant gold mineralisation associated with the extensive Alice River fault zone (>30km) and multiple sub-parallel structures at Posie and Jerry Dodds (Figure 2).
This new regional programme has concentrated outside of the main high-grade gold systems at the Central and Southern Targets with wide-spaced step out drilling intersecting gold mineralisation and confirming IP geophysics as an important gold targeting tool beneath the extensive shallow cover.
At the Northern Target, located 3km north of the Central Target, initial drilling of a 3km long ‘structural bend’ on the Alice River fault zone, defined with IP geophysics, has previously intersected broad low-grade gold (22m @ 0.2g/t Au from 35m) concealed by shallow cover[1] . At the Central Target, a similar ‘structural bend’ is directly associated with emplacement of the high-grade gold mineralisation.

Jerry Dodds and Victoria
Targeting previously completed in Q4 2023
Pacgold completed a program of shallow orientation bedrock drilling on the Southern Target in Q4 2023 (Figure 5). The program was designed to assess the effectiveness of collecting shallow bedrock samples, to define geochemical anomalies potentially associated with deeper gold mineralisation and to define potential alteration zones.
Two traverses of angled aircore holes were completed (32 holes for 243m) at a nominal hole spacing of 25m along each traverse. A 450m long traverse (‘Western Traverse’) was undertaken across the Alice River fault zone (resistivity low corridor) 300m to the SE of the Southern Target ML’s, and a second 340m long traverse (‘Eastern Traverse’) was drilled a further 800m to the SE of the first traverse. All drillholes intersected basement granite beneath sand and variable sandstone cover from 0.2m to 4m in thickness. Composite samples from 0.5m to 3.5m were collected of basement units beneath the cover for each drillhole and assayed for low level gold and a suite of pathfinder elements.
Assay results have returned strongly anomalous levels of Gold (Au), Arsenic (As), Antimony (Sb) as well as other key trace elements indicative of the alteration zones, based on analysis of Pacgold’s drilling at the Central and Southern Targets. Encouragingly, 17 of the 32 holes intersected quartz veining and/or characteristic phengite in the basement granite from both traverses. Interpretation of these geochemical anomalies is shown below in

Current Aircore Programme Q4 2024
The previously completed sighter aircore bedrock geochemical programme explored a limited extent of the known geophysical anomaly in the southern area, with the two lines separated by approximately 1km of strike. The current programme is aimed at building a far more comprehensive understanding of the distribution of the mineralisation previously delineated with Au, Sb and As anomalies, in conjunction with quartz and phengite alteration, by completing in excess of 20 separate traverses covering 8km of strike of the known IP anomaly from Big Blow to extending 2km past Jerry Dodds SE (Figure 6).

Central Target Extension
Closely spaced aircore infill lines will be competed both north and south of the main Central Target zone, aiming to better delineate step out targets for RC drilling to be completed in Q4 this year. The majority of the planned RC drilling will look to increase the strike extension of the Central Target mineralisation and delineate new zones for follow up evaluation drilling in 2025. Figure 7 below outlines the initial areas of focus for the RC exploration programme. Designs are currently being finalised and heritage clearance will be underway in the coming weeks, before scheduled commencement in early November.

Mineral Resource Estimate
A preliminary mineral resource estimation has focussed on a number of mineralised zones that had insufficient drilling density, both along strike and down dip, to produce an estimate in these zones.
In order to more accurately reflect the mineralisation drilled to date and provide a more realistic view of the mineral resources and upside potential at Alice River, the Company has elected to push back the completion of the mineral resource estimate studies to early 2025 in order to include the assays from the upcoming RC drill programme.
This announcement is approved by the Pacgold Limited Board of Directors .

APPENDIX 1. JORC CODE TABLE 1
Section 1: Sampling Techniques and Data
| CRITERIA | JORC Code explanation | Commentary |
|---|---|---|
| SAMPLING TECHNIQUES |
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 handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
Sampling methods have included surface rock chip samples. Geochemistry from rock chip samples is used semi- quantitatively to guide further exploration and is not used for Mineral Resource estimation. The accuracy of rock chip geochemistry is generally high, but these samples are often spot samples and generally not used in Mineral Resource estimation. Diamond drilling (DD), Reverse circulation (RC) drilling and Aircore drilling (AC) was used to obtain samples for geological logging and assaying. Aircore drilling was completed to sample shallow basement. Reverse circulation drilling (precollars) was used to obtain 1m samples where veining is noted. Diamond core was halved with a core saw through zones where alteration and veining were present and sampled at 1m intervals or at other intervals to match the veining and geology. The drill holes were sited to test geophysical targets/surface geochemical targets as well as previous drilling results |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
No information is available documenting measures to ensure sample representativity for surface sampling methods and open hole percussion drilling methods. These methods are not used for Mineral Resource estimation. 1m to 3m AC samples were collected using a spear of samples collected from the drillholes. 1m RC samples were automatically split using a cyclone- mounted cone splitter. 3m RC samples were automatically split as 1m samples using a cyclone-mounted cone splitter, then manually composited to 3m samples using a riffle splitter. The splitter cleaned after each interval with a compressed air gun. Core and RC samples were submitted to the laboratory and sample preparation consisted of the drying of the sample, the entire sample being crushed to 70% passing 6mm and pulverized to 85% passing 75 microns in a ring and puck pulveriser. All samples are assayed for gold by 50g fire assay with AAS finish. Multielement analysis is completed using an ICP-MS analysis. Screen fire analysis is completed on zones which contain multiple visible gold occurrences. ARDH061 ore zone interval was analysed using the screen fire assay technique. 1kg pulp wet or dry screened to 75 microns. Duplicate 30g assay on screen undersize. Assay of entire oversize fraction. |

| CRITERIA | JORC Code explanation | Commentary |
|---|---|---|
| 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 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 (e.g., submarine nodules) may warrant disclosure of detailed information. |
Economic gold mineralisation is measured in terms of parts per million and therefore rigorous sampling techniques must be adopted to ensure quantitative, precise measurements of gold concentration. If gold is present as medium – coarse grains, the entire sampling, sub-sampling, and analytical process must be more stringent. At Alice River, gold can be visible and therefore there may be inherent sampling problems. Procedures used to manage this problem are documented elsewhere in relevant sub- sections of this table. |
|
| DRILLING TECHNIQUES |
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). |
RC drilling used a 5.5” face sampling RC hammer. AC drilling used a 5.5” face sampling AC blade and/or hammer. Diamond drilling was all NQ3 (triple tube) drill diameter. Some core holes were diamond tails using RC pre-collars, others are diamond drilled from surface. Orientation gear (diamond drilling) – Electronic digital core orientation system Survey Gear – Electronic digital multi-shot magnetic survey camera |
| DRILL SAMPLE RECOVERY |
Method of recording and assessing core and chip sample recoveries and results assessed. |
For diamond core drilling core recoveries are measured by reconstructing core into continuous runs on an angle iron cradle for orientation marking. An average core recovery of greater than 98% has been achieved. No additional measures were required as core recoveries are deemed to be high, and samples considered to be representative. For RC and AC sample recoveries of less than approximately 80% are noted in the geological/sampling log with a visual estimate of the actual recovery. Very few samples were recorded with recoveries of less than 80%. No wet RC samples were recovered. No relationship has been observed between sample recovery and grade. |

| GEOLOGY | Deposit type, geological setting, and style of mineralisation. |
The Alice River Gold Project lies within the Alice-Palmer Structural Zone. Gold mineralisation is focused along regional northwest shear zones. The shear zones are largely hosted within the Imooya Granite, a pale grey to white mica-biotite leucogranite (commonly referred in the old reports as an adamellite), of the Siluro-Devonian Kintore Supersuite. At the north end of the Project area the shears intersect gneisses and schists of the Sugarbag Creek Quartzite, which forms the lower part of the Mesoproterozoic Holroyd Metamorphics. Mineralisation is considered to be Intrusion Related Gold – epithermal style. The gold-bearing shear zones extend episodically for approximately 50 km strike length. Gold mineralisation is generally hosted in quartz veins, and minor quartz breccias, up to 10 – 15 m wide in places. Gold mineralisation is focused in linear zones up to 150 m strike length. Gold occurs as both fine free gold in quartz or associated with arsenopyrite and stibnite. Green-white quartz-sericite-epidote alteration zones extend 50 – 70 m around the mineralised veins at some deposits but generally the quartz veins display narrow alteration selvages. The weathered (oxide) zones at surface are around 10 – 20 m deep. |

|
| 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. |
Unless specified otherwise, a nominal 0.5g/t Au lower cut-off has been applied incorporating up to 4m of internal dilution below the reporting cut-off grade to highlight zones of gold mineralisation. Refer Table 1 and 2. Broad lower grader zones described as mineralisation envelopes are reported using a 0.1g/t Au lower cut-off and incorporating up to 6m of internal dilution below the cut-off grade and results are shown in brackets and italics e.g. (50m @ 0.8g/t Au) No metal equivalent values have been used for reporting exploration results. To date PacGold have previously been reporting intercepts at 0.3 g/t Au and more recently at 0.5 g/t Au as well as highlighting >10 g/t Au high grade zones. These cut-offs were selected to highlight the mineralisation results that occur as narrow higher-grade veins and broader mineralisation zones comprising minor veins and alteration zones. Near surface mineralisation presents as an open pit target where 0.3 to 0.5 g/t Au presents a reasonable possible economic cut-off for bulk mining. However more recent deeper drilling by PacGold is leading into areas where underground mining is expected. Such mining might target both the narrow high-grade zones or allow larger scale bulk stoping underground mining methods. PacGold is still drill testing the extent of the mineralisation and continuity of the high-grade veins and broader mineralisation zone to determine the most likely open pit to underground interface and also the scale and likely cut-off for potential underground mine development. It is expected that exploration reporting cut-offs and criteria will be refined when these development aspects become clearer or after the initial Mineral Resource assessment refines the cut-off and thickness selections. |
| 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 |
High grade gold intervals internal to broader zones of mineralisation are reported as included intervals. A nominal 10g/t Au cut-off has been applied to reporting high grade gold intervals contained within broader zones of mineralisation. These are routinely specified in the summary results tables. |

| such aggregations should be shown in detail. |
||
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalents are reported. | |
| RELATIONSHIP BETWEEN MINERALISATION WIDTHS AND INTERCEPT LENGTHS |
These relationships are particularly important in the reporting of Exploration Results. |
The orientation of the drilling is generally perpendicular to the strike of the mineralisation but not perpendicular to the dip on the mineralisation. Generally, the true width of the mineralisation is approximately half the intercept width but until we have additional drilling to confirm the exact geometry of the mineralisation the true width is uncertain. |
| 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’). |
||
| 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. |
See body of this ASX announcement for appropriate diagrams. |
| 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. |
Balanced reporting of Exploration Results is presented. |
| OTHER SUBSTANTIVE EXPLORATION DATA |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; |
The Alice River Gold Project includes a large amount of exploration data collected by previous companies, including regional stream sediment geochemical data, soil sample and rock chip data, geological mapping data, open holepercussion drillingdata, ground magnetics,IP |

and VLF-EM geophysical survey data, and costean data. Much of this data has been captured and validated into a GIS database. Metallurgical tests of selected mineralised samples including bottle roll cyanide leach tests were conducted by Golden Plateau in 1994, Goldminco in 1999, and by Tinpitch in 2005 and 2006. Gravity concentration tests were also carried out by Goldminco in 1999. Bottle roll cyanide leach testing work produced variable results. Some samples returned low recoveries, whilst other samples produced high recoveries up to 90%. Further metallurgical work is warranted. Further information is in the IGR of the Company's IPO Prospectus released to ASX on 6 July 2021. |

| FURTHER WORK | The nature and scale of planned further work (e.g., tests for lateral extensions or depth extensions or large- scale step-out drilling). |
Pacgold plans to conduct further surface geological mapping and geochemistry, ground geophysics and Aircore, RC and Diamond drilling across three high- priority target areas over the next two years. |
