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.

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.
