What This Announcement Means

QMines has completed its 73-hole, 9,798-metre drilling campaign at the Mount Mackenzie gold and silver project in Queensland, and all assay results are now in. The key takeaway is that the North Knoll area has been confirmed as a substantial gold system stretching over 350 metres of strike length, and importantly, the mineralisation remains open at depth — meaning there is more gold to find below the current drill holes. The deeper diamond drilling at North Knoll West is particularly encouraging, with multiple holes hitting gold and silver at depths well below the previous shallow drilling, suggesting the system extends significantly downward.

The high-grade Vein 355 discovery — which previously returned a spectacular 16 metres at 19.35 g/t gold, including 1 metre at 108 g/t gold — has been further tested by infill and step-out drilling. The results show that the very high-grade zone is spatially restricted and appears to be a narrow, structurally focused ‘shoot’ rather than a broad zone. This means the bonanza grades are real but confined, and further oriented diamond drilling will be needed to chase the shoot down-dip.

With all drilling data now in hand, QMines has started formal Mineral Resource estimation work focused on the North Knoll Core area. The company has also identified that North Knoll West may represent a more proximal (deeper, hotter) part of the hydrothermal system, raising the possibility of copper-gold porphyry potential at depth. A large new drilling campaign is also being planned at the Woods Shaft deposit at the separate Mt Chalmers project.

Key Takeaways

  • The 73-hole, 9,798m drilling program at Mt Mackenzie is now complete with all assays received, confirming North Knoll as the principal gold position with mineralisation over approximately 350m of strike and remaining open at depth.
  • Deeper diamond drilling at North Knoll West returned significant intercepts including 24m @ 1.19g/t Au from 71m (MMRD060) and 7m @ 1.89g/t Au from 55m (MMRD059), confirming mineralisation continues below the shallow RC drill envelope.
  • Infill and step-out drilling at Vein 355 indicates the high-grade mineralisation (previously 16m @ 19.35g/t Au) is spatially restricted and controlled by a narrow, structurally focused shoot rather than a laterally extensive zone.
  • Mineral Resource estimation work has commenced for the North Knoll Core area, supported by approximately 8,700 assayed samples and a program-wide geological and statistical review.
  • North Knoll West geochemistry (elevated tellurium, arsenic, copper, antimony and anhydrite veining) supports interpretation as a more proximal part of the hydrothermal system, with potential copper-gold porphyry targets at depth.

Introduction

QMines Limited (QMines or Company) (ASX: QML) is pleased to report the final assay results from its 2025 to 2026 drilling program at the Mount Mackenzie gold and silver project, located near Rockhampton in Central Queensland.

The results reported in this announcement complete all outstanding assays from the program. This final batch includes diamond tail holes MMRD059 to MMRD063 at North Knoll West, Southern Extension Reverse Circulation (RC) holes MMRC021 and MMRC024 to MMRC034, the final Vein 355 infill and stepout RC holes MMRC038 to MMRC057, and diamond hole MMDD012 at Vein 355. Two holes, MMRC037 and MMRC058, were abandoned prior to reaching target depth and as a result were not sampled and are excluded from the reported assay results.

Receipt of these final results brings the full QMines drilling program to 73 holes for 9,798m, covering the North Knoll Core, North Knoll West Extension, Southern Extension, Vein 355 and Mount Mackenzie South target areas.

The Company has also completed a program wide geological, geochemical and statistical review, drawing on the complete assay and logging database. This integrated dataset provides a robust technical basis for the Mineral Resource estimation work that is now underway.

Management Comment

Exploration Manager, Tom Bartschi, commented

“The completion of this program provides a substantial drilling, assay and logging dataset for Mount Mackenzie. The final results from the deeper western diamond holes are important because MMRD059 and MMRD060 test the North Knoll system below much of the previous shallow RC drilling. These holes provide additional evidence that mineralisation extends to depth, with observed grade, width and continuity supporting the current geological interpretation of the system.

The program wide review has integrated the drilling, assay, lithological, alteration and geochemical datasets to better understand the controls on gold mineralisation. The review indicates that alteration is the primary control on mineralisation, with structure acting as an important secondary control. Depth is also a relevant variable, although the available data do not support a simple depth limited model. When considered together with the pathfinder geochemistry, these relationships support a coherent geological framework for ongoing drill targeting.

The dataset is now being advanced through Mineral Resource estimation, with the North Knoll Core representing the most mature area based on grade, geological continuity and drill spacing. North Knoll West remains an important follow-up target, with the recent diamond drilling confirming mineralisation below the shallow RC envelope and providing a deeper vector for future drilling.”

Program Overview

The completed Mount Mackenzie program comprises 73 holes for 9,798m including 58 RC holes for 5,988m, 9 diamond holes for 2,261m and 6 RC holes with diamond tails for 1,549m. The program was supported by approximately 8,700 assayed samples which tested five key areas across the project: North Knoll Core, North Knoll West, the Southern Extension, Vein 355 and Mt Mackenzie South. Two holes that were abandoned prior to reaching target depth were not sampled and are excluded from the reported assay results. A further deposit called South West Slopes was not drilled during this program, with drilling on company owned land prioritised.

At the commencement of the program, Mount Mackenzie was defined primarily by shallow historic open hole percussion drilling, the majority of which was less than 100m deep, with limited testing below 200m. The program was designed to confirm the historic shallow mineralisation, test strike continuity and determine whether the system persisted at depth.

Program Achievements

The program has delivered on each of these objectives and has materially advanced the Company’s geological understanding of Mount Mackenzie. Key outcomes include the discovery of high-grade gold at Vein 355 and the recognition of Mount Mackenzie as a vertically extensive high-sulphidation epithermal system, with alteration, geochemistry and depth continuity supporting further drill targeting.

Key achievements of the program include:

  • Interception of the Vein 355 high-grade position, headlined by 16m @ 19.35g/t Au from 8m including 1m @ 108g/t Au from 11m in MMDD010, the highest individual gold assay returned from the program3;
  • Confirmation of a coherent mineralised corridor at North Knoll Core over approximately 350m of strike, supported by intercepts including 15m @ 5.10g/t Au from 17m (MMRC014)4, 11m @ 4.63g/t Au from 47m (MMRC004)5, 18m @ 3.40g/t Au from 36m, including 2m @ 16.01g/t Au (MMRC013)4, 15m @ 3.59g/t Au from 20m (MMRC012)4 and 14m @ 3.04g/t Au from 21m (MMDD011)6;
  • Demonstration that high-grade gold mineralisation persists below the historic shallow drill envelope, including 6m @ 10.47g/t Au from 118m in MMDD009 and further deeper diamond drilling results from North Knoll West reported in this announcement6;
  • Establishment of an integrated geological framework for the system, including alteration zonation, structural controls, pathfinder geochemistry and depth continuity, supported by program-wide statistical analysis; and
  • Delivery of a statistically reviewed and QAQC-supported dataset suitable for advancing Mineral Resource estimation work.

Drill Results

North Knoll West

The five deeper diamond tail holes completed at North Knoll West represent the key results from the final assay batch. The holes were drilled as a westward-stepping fence to test the western extension of the North Knoll corridor below much of the previous shallow RC drilling.

MMRD060 returned a broad mineralised interval of 24m @ 1.19g/t Au and 13.3g/t Ag from 71m, including 2m @ 2.61g/t Au and 33.4g/t Ag from 78m, with a peak assay of 3.48g/t Au. The hole also returned 10m @ 0.58g/t Au from 99m. A shallower zone of 9m @ 0.86g/t Au and 14.4g/t Ag from 58m confirms mineralisation is developed across multiple levels, while narrow anomalism near the end of hole indicates the hydrothermal system remains geochemically active at depth.

MMRD059 returned 7m @ 1.89g/t Au and 34.6g/t Ag from 55m including 4m @ 3.08g/t Au and 56.2g/t Ag from 55m, with individual silver assays up to 67.6g/t Ag. The hole also returned 4m @ 1.27g/t Au and 18.9g/t Ag from 43m. The elevated silver relative to gold is interpreted to reflect a structurally focused position within the broader hydrothermal system. A deeper interval of 2m @ 0.66g/t Au from 197m confirms mineralisation persists below the main enrichment zone.

MMRD061 returned 12m @ 1.35g/t Au and 8.4g/t Ag from 121m including 2m @ 4.17g/t Au and 32.7g/t Ag from 128m, with a peak assay of 7.30g/t Au. MMRD062 returned 13m @ 0.68g/t Au and 2.3g/t Ag from 140m, while MMRD063 returned 3m @ 0.62g/t Au from 127m within broader low-grade anomalism extending to 217m.

The progressive deepening of mineralised intercepts westward along the fence, from 55m in MMRD059 to 140m in MMRD062, is consistent with the south-southwest dipping structural control interpreted across the broader North Knoll corridor.

The geochemical character of the North Knoll West holes differs from the main North Knoll Core position. Elevated tellurium, arsenic, copper and antimony, together with anhydrite stockwork veining previously documented in MMDD007 and MMDD008, support the Company’s interpretation that North Knoll West may represent a more proximal part of the hydrothermal system. This area remains a priority for future deeper diamond drilling to test below the current drill limit

Southern Extension

RC drilling across the Southern Extension, located between North Knoll Core and Vein 355, returned results that confirm structurally controlled mineralisation across this part of the corridor. Grades are generally lower than those returned from North Knoll Core; however, several holes returned mineralised intervals that support the continuity of the broader system.

MMRC024 was the standout result from this area, returning 9m @ 1.17g/t Au and 14.1g/t Ag from 130m, including 2m @ 2.34g/t Au and 36.2g/t Ag from 135m, with a peak assay of 2.62g/t Au. MMRC021 returned 6m @ 0.88g/t Au and 6.8g/t Ag from 125m, with individual samples up to 1.75g/t Au. Together, these holes support the continuation of the North Knoll structural trend to the south, towards the South West Slopes Deposit.

MMRC033, located near the eastern margin of the Southern Extension, returned 6m @ 1.85g/t Au from 10m, including 2m @ 3.88g/t Au from 13m. The shallow depth and higher-grade core are consistent with a structurally focused, near-surface mineralised zone at this location. Additional anomalous intervals were returned in MMRC026, which intersected 8m @ 0.45g/t Au and 2.9g/t Ag from 46m, and MMRC030, which intersected 5m @ 0.50g/t Au and 7.7g/t Ag from 55m.

MMRC032 returned a series of narrow intervals at or above cut-off through a broader anomalous zone from 32m to 64m, consistent with the outer halo of the system. MMRC025, MMRC027, MMRC028, MMRC029, MMRC031 and MMRC034 returned narrow or low-grade intervals, consistent with their interpreted positions toward the margin of the currently defined mineralised corridor.

Vein 355 Infill and Step-Out

Infill and step-out RC drilling at Vein 355 was designed to test the lateral extent of the high-grade position defined by MMDD010 and MMRC035 earlier in the program. Results from this batch indicate that the high-grade mineralisation at Vein 355 is spatially restricted within the area tested to date.

MMRC046 returned 2m @ 1.01g/t Au and 4.3g/t Ag from 7m, including a peak assay of 1.27g/t Au, and is located immediately adjacent to the MMDD010 position. The result confirms shallow mineralisation within the near-surface oxide zone at the northern end of the Vein 355 corridor.

MMRC054 returned 2m @ 1.25g/t Au and 2.5g/t Ag from 33m, with a peak assay of 2.21g/t Au, confirming that the mineralised structural corridor extends south of the MMRC035 position.

MMDD012 was drilled as an additional diamond hole to obtain structural orientation of structures within Vein 355 high-grade position and returned 4m @ 2.04g/t Au and 25.89g/t Ag from 17m. The result confirms further gold-silver mineralisation within the Vein 355 structure. Together with the broader infill and step-out results, MMDD012 supports the interpretation that the high-grade Vein 355 mineralisation is controlled by a narrow, structurally focused shoot rather than a laterally extensive high-grade zone.

The remaining step-out holes in this batch, including MMRC038 to MMRC045 and MMRC050 to MMRC057, returned low-grade or anomalous results only. These results, together with the moderate-grade intercept in MMDD012, indicate that the high-grade Vein 355 position does not extend broadly across the tested footprint and is more likely to represent a structurally focused shoot within a narrow, steeply dipping vein-breccia corridor.

Further oriented diamond drilling is planned to resolve the geometry and plunge of the mineralised shoot and test potential down-dip extensions of the MMDD010 and MMRC035 intersections.

Program Completion

Program-Wide Geological & Statistical Review

Completion of the final assay batch has enabled QMines to complete a program-wide internal review of the Mount Mackenzie dataset. The review integrates geological observations from diamond core logging with statistical analysis of the approximately 8,700-sample assay database. The key findings are summarised below.

Gold Grade Controls

The review identified three principal controls on gold grade at Mount Mackenzie: Alteration, structure and depth. These controls are supported by statistical analysis of the full dataset and provide an improved framework for future drill targeting.

Alteration: Alteration is interpreted to be the primary control on gold distribution. Advanced argillic alteration carries a mean gold grade of 0.34g/t Au and has an approximately 70 times higher probability of exceeding 1.0g/t Au than propylitic altered material. Silica-pyrite alteration is the main host by sample volume and carries gold grades above propylitic background. Propylitic alteration is generally weakly mineralised. This pattern is consistent with a high-sulphidation lithocap setting, where alteration zonation reflects the architecture of the hydrothermal system.

Structure: Gold is preferentially concentrated in moderately broken, structurally prepared ground. Corrected analysis of rock quality designation from diamond core indicates that the 10% to 25% RQD band carries a median gold grade approximately six times higher than intact rock. This relationship is also observed in fresh rock, supporting the interpretation that it reflects a structural control rather than a weathering effect. High-grade zones in diamond core commonly begin and end abruptly over metre-scale intervals, consistent with structurally bounded breccia conduits rather than broadly disseminated mineralisation.

Depth: Gold grades are strongest within the shallow enriched shell, with mean grade decreasing from approximately 0.32g/t Au in the upper 50m to approximately 0.03g/t Au below 150m. Despite this overall depth trend, deeper structurally controlled high-grade zones persist to the current drill limit, including 6m @ 10.47g/t Au from 118m in MMDD009 and the North Knoll West results from MMRD059 and MMRD060 reported in this announcement. The system is interpreted as a shallow gold-rich shell with discrete deeper mineralised shoots and remains open at depth.

Pathfinder Geochemistry

A coherent high-sulphidation pathfinder signature has been defined across the full dataset. Silver is the strongest co-enriched element associated with gold, followed by lead, antimony, tellurium, copper and arsenic. Zinc is inversely correlated with gold, which is interpreted to reflect acid leaching within the lithocap core. This zinc depletion is most pronounced in the higher-grade gold samples and provides a useful vector toward the productive core of the system.

The combined Au-Ag-Sb-Pb-Cu-Te-As association, together with zinc depletion, is consistent with a gold-bearing high-sulphidation epithermal system developed within an acidic lithocap. Principal component analysis of the multi-element dataset supports this interpretation as a coherent geochemical signal. A combined pathfinder intensity score has also been developed to assist with prioritising future drill targets independent of gold grade.

Mineralisation Model

The integrated dataset supports the interpretation of Mount Mackenzie as a high-sulphidation epithermal system developed within a vertically extensive lithocap. The alteration architecture, sulphide assemblage, pathfinder geochemistry, depth distribution of gold and structural controls are consistent with this framework.

At North Knoll West, the enargite-bearing sulphide interval in MMDD007, together with anhydrite stockwork veining, elevated tellurium and copper, and persistent gold below the main shallow enrichment zone, are interpreted to indicate a more proximal part of the hydrothermal system. This supports further assessment of the deeper feeder architecture and any associated copper-gold porphyry potential at depth.

The defined mineralised zones at North Knoll and Vein 355 together represent a gold-bearing epithermal field, with mineralisation confirmed from surface to depth and remaining open in selected areas along strike and at depth. The progressive deepening of significant intercepts across the North Knoll drill fences provides a clear structural vector for future drilling.

Next Steps

With all assays now received and the program wide review complete, the Company is focused on the following priorities:

  • progressing Mineral Resource estimation work for North Knoll Core, supported by the complete QMines assay database, geological logging, alteration interpretation and structural framework;
  • planning a deeper diamond drill hole at North Knoll West to test the transition from lithocap alteration into the interpreted alteration root zone and assess deeper copper-gold potential;
  • planning oriented diamond drilling at Vein 355 to better define the structural geometry controlling the higher-grade shoot and test potential down-dip extensions below the MMDD010 and MMRC035 intersections; and
  • finalising the updated structural interpretation, incorporating oriented core data from the completed program to guide targeting for future drilling phases.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

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.
  • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
  • 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.
  • The results reported in this announcement relate to reverse circulation drilling, diamond drilling and RC pre-collar with diamond tail drilling completed by QMines at the Mount Mackenzie gold and silver project. RC samples were collected at nominal 1m downhole intervals from the drilling rig. Diamond core was geologically logged and sampled at nominal 1m intervals, adjusted where appropriate to geological, alteration, oxidation and mineralisation boundaries. Diamond core samples were generally submitted as half core, with remaining half core retained for reference. Quarter core duplicates were collected at selected intervals as part of the QAQC program. Sampling was designed to provide representative material for gold, silver and multi-element analysis. The sample interval selection, geological logging and QAQC procedures are considered appropriate for the style of gold-silver mineralisation being tested.
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.).
  • Drilling comprised RC drilling, diamond drilling and RC pre-collar with diamond tail drilling. RC drilling was used to test near surface and intermediate depth targets across North Knoll Core, North Knoll West, Southern Extension, Vein 355 and Mount Mackenzie South. Diamond drilling was used to obtain oriented and continuous core through key mineralised positions, deeper target areas and structurally complex zones. Diamond drilling included HQ3 triple tube core drilling where required to maximise recovery through altered and broken ground. Core orientation was completed where practicable using an AXIS CHAMP ORI or equivalent core orientation system. Downhole surveys were completed using gyro survey equipment at regular intervals and at end of hole. Final collar details, including hole depth, dip, azimuth, RL and drilling method, are provided in the drillhole collar table in this announcement.
Drill sample recovery
  • Method of recording and assessing core and chip sample recoveries and results assessed.
  • Measures taken to maximise sample recovery and ensure representative nature of the samples.
  • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
  • RC sample recovery was monitored at the rig by field geologists and drilling personnel, with sample condition recorded where relevant. Diamond core recovery was measured and recorded by run. Triple tube diamond drilling was used where appropriate to improve recovery through altered, fractured or rubbly intervals. No material relationship between sample recovery and grade has been identified from the drilling completed to date. However, local nugget effects and grade variability are recognised in high grade Vein 355 mineralisation, particularly where coarse gold or rubbly breccia textures are present.
Logging
  • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
  • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.
  • The total length and percentage of the relevant intersections logged.
  • All RC chips and diamond core were geologically logged by QMines geologists. Logging included lithology, alteration, oxidation, veining, brecciation, sulphide abundance, sulphide mineralogy, structure and mineralisation. Diamond core was also geotechnically logged where appropriate, including recovery, RQD and structural observations. Logging was qualitative to semi-quantitative in nature and is considered sufficient to support geological interpretation, drill targeting and the Mineral Resource estimation work now underway for North Knoll Core. All diamond core was photographed prior to cutting and sampling.
Sub-sampling techniques and sample preparation
  • If core, whether cut or sawn and whether quarter, half or all core taken.
  • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.
  • For all sample types, the nature, quality and appropriateness of the sample preparation technique.
  • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
  • Measures taken to ensure that the sampling is representative of the in-situ material collected, including for instance results for field duplicate/second-half sampling.
  • Whether sample sizes are appropriate to the grain size of the material being sampled.
  • RC samples were collected at nominal 1m intervals and submitted for laboratory analysis. Diamond core was cut by diamond saw, with half core submitted for assay and the remaining half core retained. Quarter core duplicates were collected at selected intervals. Sample preparation was undertaken by ALS Townsville or the ALS laboratory network using industry standard preparation procedures, including drying, crushing and pulverising to produce a representative pulp for analysis. The sample sizes are considered appropriate for the grain size and style of mineralisation being tested, noting that local coarse gold and nugget effects may be relevant in high grade Vein 355 material.
Quality of assay data and laboratory tests
  • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
  • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
  • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
  • Samples were submitted to ALS for gold, silver and multi-element analysis. Gold was analysed by fire assay using method Au-AA25. Silver was analysed using method Ag-AA45, and multi-element geochemistry was analysed by ICP using method ME-ICP61. Certified reference materials, blanks and field duplicates were inserted into the sample stream at regular intervals as part of the QMines QAQC program, with laboratory internal QAQC also completed by ALS. Review of the QAQC data indicates analytical performance is acceptable for the reporting of Exploration Results, with no material QAQC issues identified that would affect the results reported in this announcement. Overgrade gold was reassayed using Au-GRA21 gravimetric finish.
Verification of sampling and assaying
  • The verification of significant intersections by either independent or alternative company personnel.
  • The use of twinned holes.
  • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
  • Discuss any adjustment to assay data.
  • Significant intersections were checked against original assay certificates, geological logs and drillhole data. Results were reviewed by QMines technical personnel and the Competent Person. Assay results were imported into the Company database and validated prior to interpretation and reporting. No adjustments were made to the primary assay data, other than standard treatment of below detection limit values where required for statistical analysis. Reported intersections are based on laboratory assay results.
Location of data points
  • Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
  • Specification of the grid system used.
  • Quality and adequacy of topographic control.
  • Drillhole collar locations were recorded using handheld GPS during drilling and subsequently picked up by DGPS where available. Coordinates are reported in GDA2020, MGA Zone 55. RL values are based on surveyed collar positions and available topographic data. Downhole surveys were completed using gyro survey methods at regular intervals and at end of hole. Final collar coordinates, RL, dip, azimuth and end of hole depths are provided in the drillhole collar table.
Data spacing and distribution
  • Data spacing for reporting of Exploration Results.
  • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
  • Whether sample compositing has been applied.
  • The program comprised 73 holes for 9,798m of drilling across North Knoll Core, North Knoll West, Southern Extension, Vein 355 and Mount Mackenzie South. Drill spacing varies by area, reflecting the staged exploration nature of the program. North Knoll Core has the closest drill spacing and best demonstrated continuity, and is considered the most advanced area for Mineral Resource estimation. North Knoll West, Southern Extension and Vein 355 remain at exploration stage, with drilling designed to test extensions, structural controls and target geometry. Sample compositing has been used for reporting significant intersections, but not for primary laboratory analysis.
Orientation of data in relation to geological structure
  • Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
  • 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.
  • Drillhole orientation was designed to test interpreted mineralised structures and alteration zones based on available geological mapping, historical drilling, surface geochemistry, geophysics and previous QMines drilling. At North Knoll, inclined holes were generally designed to test interpreted southwest dipping or structurally controlled mineralisation. At Vein 355, some holes were drilled steeply or vertically due to terrain, access and program design constraints. As a result, true widths are not yet known and all reported intersections are downhole lengths. Additional oriented diamond drilling is required at Vein 355 to resolve the geometry, true width and plunge of the high grade mineralised shoot.
Sample security
  • The measures taken to ensure sample security.
  • Samples were collected, bagged and recorded by QMines personnel or contractors under QMines supervision. Samples were transported to the laboratory using standard chain of custody procedures. Sample submission records and laboratory dispatch documentation were maintained.
Audits or reviews
  • The results of any audits or reviews of sampling techniques and data.
  • Internal reviews of drilling, logging, sampling, assay and QAQC data were completed by QMines technical personnel. Completion of the final assay batch has enabled a program wide geological, geochemical and statistical review of the complete Mount Mackenzie dataset. No external audit of the full drilling database has been completed at this stage. The dataset is considered suitable for reporting exploration results and for advancing Mineral Resource estimation work at North Knoll Core, subject to normal validation and Competent Person review.

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria JORC Code explanation Commentary
Mineral tenement and land tenure status
  • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
  • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
  • All datasets, drilling and derived targets lie within MDL2008, held 100% by Mount Mackenzie Mines (wholly owned subsidiary of QMines Limited). Tenement in good standing, no known impediments.
Exploration done by other parties
  • Acknowledgment and appraisal of exploration by other parties.
  • Mt Mackenzie explored intermittently since the 1970s by multiple parties. Historic drilling >600 holes, predominantly shallow (<100m). Historical IP surveys: 1984 dipole-dipole (Peabody/Utah) providing foundational electrical dataset for northern and central project; 2002 OPD (SmartTrans/Arctan) overlapping and extending central coverage. QMines compiled and reviewed all historic datasets.
Geology
  • Deposit type, geological setting and style of mineralisation.
  • Mount Mackenzie is a high sulphidation epithermal Au-Ag-Cu system in altered volcanic sequences of the Connors-Auburn magmatic arc. Advanced argillic alteration, vuggy silica, and enargite-bearing sulphide assemblages confirmed by drilling. IP responses interpreted in context of this model, with chargeability and resistivity contrasts mapping silicification, sulphidation and clay alteration typical of high sulphidation lithocaps (Sillitoe, 2010; Hedenquist & Taran, 2013; Cooke et al., 2017).
Drill hole Information
  • 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.
  • 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.
  • Drillhole collar information, including hole ID, easting, northing, RL, dip, azimuth, end of hole depth, drilling method and prospect area, is provided in the drillhole collar table in this announcement. The final assay batch includes diamond holes MMRD059 to MMRD063 at North Knoll West, MMDD012 at Vein 355, RC holes MMRC021 and MMRC024 to MMRC034 at Southern Extension, and RC holes MMRC038 to MMRC057 at Vein 355. Two holes, MMRC037 and MMRC058, were abandoned prior to reaching target depth and are excluded from the reported assay results.
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.
  • 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.
  • The assumptions used for any reporting of metal equivalent values should be clearly stated.
  • Significant intersections are reported using a lower cut off of 0.2g/t Au, unless otherwise stated. For drill holes first reported in this announcement, significant intercepts use a 0.2g/t Au lower cut-off with no internal dilution: every assayed sample within a reported interval is at or above cut-off, and intervals are bounded by sub-cut-off, unassayed or absent samples. Intercepts for holes previously reported to the ASX are reproduced unchanged from the relevant prior announcement and may have applied a different aggregation convention, including limited internal dilution; refer to the original announcements for their basis. Higher grade included intervals are reported using a higher cut off where appropriate. No top cuts have been applied to exploration results. Metal equivalent values are not reported. Length weighted average grades are used for all reported composite intervals.
Relationship between mineralisation widths and intercept lengths
  • 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’).
  • All reported intersections are downhole lengths. True widths are not yet known. The geometry of mineralisation varies between target areas and remains subject to further drilling and structural interpretation. At North Knoll, drilling indicates multiple mineralised zones with structural and alteration controls. At Vein 355, current drilling indicates a narrow, steeply dipping structurally controlled shoot, but additional oriented diamond drilling is required to resolve true width, plunge and continuity.
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.
  • Appropriate plans, sections and drillhole location figures are included in the announcement. These show drillhole collar locations, prospect areas, reported intersections and interpreted mineralised trends.
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 material results from the final assay batch are reported in this announcement. Holes that returned low grade, anomalous or no significant intersections are discussed in the text where relevant. Two holes abandoned prior to reaching target depth, MMRC037 and MMRC058, are excluded from the reported assay results. The announcement also distinguishes between the more advanced North Knoll Core area, the deeper North Knoll West target, the transitional Southern Extension area, the spatially restricted Vein 355 high grade position and the lower priority Mount Mackenzie South area.
Other substantive exploration data
  • 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.
  • The announcement incorporates geological logging, alteration interpretation, structural observations, multi-element geochemistry and statistical analysis of the complete assay database of approximately 8,700 samples. Pathfinder geochemistry includes Au, Ag, Sb, Pb, Cu, Te and As, with zinc depletion interpreted as a vector toward the more strongly altered lithocap core. Previous diamond drilling at North Knoll West identified enargite bearing sulphide mineralisation, anhydrite stockwork veining and elevated tellurium and copper, supporting the interpretation of a more proximal part of the hydrothermal system.
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).
  • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
  • Mineral Resource estimation work is underway for North Knoll Core. Further work will include planning a deeper diamond drill hole at North Knoll West to test below the current drill limit and assess the transition from lithocap alteration into the interpreted alteration root zone. Oriented diamond drilling is also warranted at Vein 355 to resolve the structural geometry controlling the higher grade shoot and to test potential down-dip extensions below the MMDD010 and MMRC035 intersections. The Company is also finalising an updated structural interpretation incorporating oriented core data from the completed program to guide future drilling.

Frequently Asked Questions

The following Q&A is AI-generated from the announcement content and is provided as a supplementary reader aid only.

What is the significance of the North Knoll West diamond drilling results?

The five deeper diamond tail holes at North Knoll West confirm that mineralisation continues below the shallow RC drill envelope. Key intercepts include 24m @ 1.19g/t Au and 13.3g/t Ag from 71m (MMRD060) and 7m @ 1.89g/t Au and 34.6g/t Ag from 55m (MMRD059). The progressive deepening of mineralised intercepts westward along the drill fence is consistent with a south-southwest dipping structural control, and the area remains a priority for future deeper diamond drilling.

What happened with the high-grade Vein 355 infill and step-out drilling?

Infill and step-out RC drilling at Vein 355 indicates that the high-grade mineralisation is spatially restricted within the area tested to date. The remaining step-out holes returned low-grade or anomalous results only. The results indicate the high-grade Vein 355 position is more likely to represent a structurally focused shoot within a narrow, steeply dipping vein-breccia corridor. Further oriented diamond drilling is planned to resolve the geometry and plunge of the mineralised shoot and test potential down-dip extensions.

What are the three main controls on gold grade identified at Mount Mackenzie?

The program-wide review identified three principal controls: alteration, structure and depth. Alteration is the primary control, with advanced argillic alteration having approximately 70 times higher probability of exceeding 1.0g/t Au than propylitic altered material. Structure is an important secondary control, with the 10% to 25% RQD band carrying a median gold grade approximately six times higher than intact rock. Depth shows an overall trend of decreasing grade, from approximately 0.32g/t Au in the upper 50m to approximately 0.03g/t Au below 150m, though deeper structurally controlled high-grade zones persist to the current drill limit.

What is the next step for the Mount Mackenzie project?

The Company has commenced Mineral Resource estimation work for the Mount Mackenzie project, focused initially on the North Knoll Core area. Additional priorities include planning a deeper diamond drill hole at North Knoll West to test the transition from lithocap alteration into the interpreted alteration root zone and assess deeper copper-gold potential, planning oriented diamond drilling at Vein 355 to better define the structural geometry, and finalising the updated structural interpretation incorporating oriented core data.

How many holes and metres were drilled in the total Mount Mackenzie program?

The completed Mount Mackenzie program comprises 73 holes for 9,798m including 58 RC holes for 5,988m, 9 diamond holes for 2,261m and 6 RC holes with diamond tails for 1,549m. The program was supported by approximately 8,700 assayed samples which tested five key areas: North Knoll Core, North Knoll West, the Southern Extension, Vein 355 and Mt Mackenzie South.

What does the geochemistry at North Knoll West suggest about deeper potential?

The geochemical character of the North Knoll West holes differs from the main North Knoll Core position. Elevated tellurium, arsenic, copper and antimony, together with anhydrite stockwork veining previously documented in MMDD007 and MMDD008, support the Company’s interpretation that North Knoll West may represent a more proximal part of the hydrothermal system. This supports further assessment of the deeper feeder architecture and any associated copper-gold porphyry potential at depth.
