What This Announcement Means

QMines had a very productive quarter focused on drilling at their Mount Mackenzie gold-silver project. The company drilled nearly 7,000 metres and hit some spectacular high-grade gold results, including 16 metres averaging almost 20 grams per tonne of gold – that’s bonanza-grade material. They also identified five new targets across a large 1.2km area, showing the project has significant growth potential beyond what they’ve already found.

The company also upgraded their Develin Creek copper-zinc resource by 14% and started the definitive feasibility study for their flagship Mt Chalmers copper-gold project. Most importantly, they secured $15 million in funding from Queensland Investment Corporation after quarter-end, which should fully fund them through to a final investment decision on Mt Chalmers. This puts QMines in a strong position to advance toward becoming Queensland’s next copper and gold producer.

With three quality projects in their portfolio – Mt Chalmers (copper-gold), Develin Creek (copper-zinc), and Mt Mackenzie (gold-silver) – all located within 90km of Rockhampton, QMines is building a compelling regional hub strategy in an area with excellent infrastructure and mining history.

Introduction

QMines Limited (QMines or Company)(ASX:QML) is pleased to announce its March Quarterly Activities Report for what has been another very busy quarter for the Company. During the Quarter, the Company advanced several exploration and development workstreams across its Central Queensland portfolio. The Mount Mackenzie Gold Silver Project remained the principal exploration focus, with drilling progressing across priority high sulphidation gold and silver targets at North Knoll, the Western Extension area and Vein 355.

At Develin Creek, the Company reported an upgraded Mineral Resource Estimate and commenced optimisation work to assess future integration of Develin Creek mineralisation into the broader Mt Chalmers hub strategy. Field activity at Develin Creek during the quarter was limited to site support, logistics and progressive rehabilitation.

At Mt Chalmers, geotechnical drilling, packer testing, environmental baseline work, mineragraphy and improved geological modelling activities were initiated. These activities are designed to support engineering, approvals and technical inputs for the Mt Chalmers Definitive Feasibility Study (DFS).

Mount Mackenzie Project (Gold-Silver)

During the quarter, QMines continued its maiden Mount Mackenzie drilling program, located approximately 120km northwest of the Mt Chalmers Hub. Drilling was undertaken using a combination of RC and diamond methods to test high priority positions within the broader high sulphidation epithermal system.

The program progressed from deeper diamond drilling at North Knoll into Reverse Circulation (RC) and mixed RC diamond drilling across the western extension area and Vein 355. The work tested near surface mineralisation, extensions to known mineralised corridors and deeper structural positions interpreted to be important controls on the gold and silver system.

Reprocessing historical Induced Polarisation (IP) data and 3D inversion modelling materially improved the Company’s understanding of the shallow hydrothermal architecture at Mount Mackenzie. The updated interpretation identified five undrilled near surface targets across a 1.2km x 750m footprint, including two annular lithocap style centres and three sulphide bearing structural conduit targets adjacent to the North Knoll and South West Slopes deposits.

By 31 March, total cumulative Mount Mackenzie drilling reached 6,684.5m RC and 3,010.3m diamond for a total of 9,694.8m drilled. Drilling was approaching completion at quarter end, with final sample dispatch, core processing, DGPS collar pickups, demobilisation and progressive rehabilitation being planned or underway.

Mount Mackenzie Results & Interpretation

Assay results released during the quarter continued to support the interpretation of Mount Mackenzie as a high sulphidation epithermal gold silver system with local high-grade zones and a broader lithocap scale alteration footprint. Significant results released during the period included:

  • MMDD010: 16m @ 19.35g/t Au and 27.8g/t Ag from 8m, including
    • 12m @ 25.42g/t Au and 32.4g/t Ag from 10m,
    • 2m @ 91.75g/t Au and 81.0g/t Ag from 11m, and
    • 1m @ 94.30g/t Au and 77.9g/t Ag from 20m.1
  • MMDD009: 15.8m @ 2.58g/t Au and 7.1g/t Ag from surface, including
    • 6.8m @ 3.24g/t Au and 8.4g/t Ag from 9m, and a separate
    • 6m @ 10.47g/t Au and 39.7g/t Ag from 118m.1
  • MMDD006: 19m @ 1.13g/t Au, 11.5g/t Ag and 454ppm Cu from 85m, including
    • 5m @ 3.46g/t Au, 25.4g/t Ag and 1,185ppm Cu from 96m.2
  • MMDD007: 1m @ 3.01g/t Au, 93.8g/t Ag and 1.55% Cu from 171m, within a broader sulphide envelope.2
  • MMDD008: 16m @ 0.38g/t Au and 8.1g/t Ag from 90m, including
    • 4m @ 1.06g/t Au and 23.0g/t Ag from 95m.2

The March diamond drilling results materially improved geological confidence at North Knoll. The data confirmed multiple stacked gold silver positions, copper bearing high sulphidation mineralisation at depth and a pathfinder assemblage consistent with a fertile lithocap setting. These results support continued evaluation of deeper feeder positions, while recognising that the presence of a porphyry system remains to be tested by deeper drilling.

Mt Chalmers DFS Workstreams

During the quarter, QMines advanced DFS support activities at the Mt Chalmers Copper Gold Project2. Field activities during the period were focused on geotechnical, environmental, hydrological, mineralogical and geological inputs required for the DFS in support of the Company’s staged development strategy and future approvals pathway, beginning with the proposed 1Mtpa base case operation. The DFS builds on the Company’s 2024 Pre Feasibility Study which returned a Net Present Value (NPV) of $373 million, with a 54% IRR on a 10.4 year mine life, and generating a life of mine revenue of A$1.64 billion.3

Geotechnical drilling commenced during March, with packer testing and downhole data collection underway to support pit, waste storage and infrastructure design inputs. Four groundwater monitoring bores were also completed to support baseline groundwater studies.

Environmental baseline work progressed during the quarter, including flora surveys across the northern portion of the Mining License Application (MLA). Mineragraphy and geological model updates also advanced, providing further technical inputs for mining, processing and study optimisation work.

Develin Creek Resource Upgrade

No drilling was completed at Develin Creek during the March quarter. Field activity was limited to site support, logistics and progressive rehabilitation following completion of the 2025 drilling program in the prior quarter.

During the quarter, QMines reported an upgraded Develin Creek Mineral Resource Estimate (MRE)1 of 4.70Mt @ 0.94% Cu, 1.00% Zn, 0.15g/t Au and 5.7g/t Ag at a 0.30% Cu cut off. The update increased total Mineral Resource tonnes by 14% and increased Indicated Resources to 4.22Mt @ 0.98% Cu and 1.08% Zn, now representing approximately 90% of the total resource.

The improved MRE confidence provides a strong technical basis for expansion planning, underground optimisation studies, targeted infill or extension drilling, metallurgical variability work and future assessment of Develin Creek mineralisation as a potential feed source for the Mt Chalmers hub.

Post Quarter Activities

Subsequent to quarter end, QMines continued to advance both its Mt Chalmers development pathway and Mount Mackenzie exploration program.

At Mount Mackenzie, further assay results extended the high-grade gold corridor, with broad and shallow gold silver mineralisation returned from both North Knoll and Vein 355. Significant intercepts included2:

  • 14m @ 3.04g/t Au and 7.2g/t Ag from 21m (MMDD011); including;
  • 3m @ 7.26g/t Au and 7.5g/t Ag from 29m.
  • 6m @ 3.85g/t Au and 5.7g/t Ag from 24m (MMRC035); including
  • 1m @ 19.85g/t Au and 11.0g/t Ag from 24m.
  • 7m @ 1.23g/t Au and 6.7g/t Ag from 62m; within
  • 24m @ 0.63g/t Au and 4.3g/t Ag from 47m (MMRC018).

Strengthened Balance Sheet & Funding Position

During the March 2026 quarter, QMines continued to strengthen its financial and corporate position as the Company advances toward completion of the Mt Chalmers DFS and a Final Investment Decision (FID).

Subsequent to quarter end, the Company announced a strategic $15 million funding package with the Queensland Investment Corporation (QIC) Critical Minerals and Battery Technology Fund.3 The transaction comprises a combination of equity investment and royalty funding and is expected to fully fund QMines through completion of the DFS and toward FID for the Mt Chalmers Copper and Gold Project.

The investment from QIC represents a significant endorsement of the quality of the Mt Chalmers Project, QMines’ broader regional growth strategy, and the increasing strategic importance of copper and critical minerals supply chains in Queensland.

In addition, the Company repaid two outstanding loan facilities for a total of $1.0m, simplifying the Company’s balance sheet and reducing near-term financial obligations. The repayment of these facilities positions the Company with a cleaner and more streamlined capital structure as it progresses toward development activities.

The Company believes the combination of strengthened funding support, reduced debt obligations and continued advancement of technical studies places QMines in a strong position to progress its strategy of becoming Queensland’s next copper and gold producer.

Payments made to related parties and their associates noted in section 6 of the attached quarterly cash flow report were for consulting fees, salaries and superannuation.

Frequently Asked Questions

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

What were the best drilling results from Mount Mackenzie this quarter?

The standout result was 16.0m @ 19.35g/t Au and 27.8g/t Ag from 8m in hole MMDD010, including exceptional high-grade zones of 2m @ 91.75g/t Au and 81.0g/t Ag from 11m. Other significant intercepts included 6.0m @ 10.47g/t Au and 39.7g/t Ag from 118m and 15.8m @ 2.58g/t Au and 7.1g/t Ag from surface.

How much drilling was completed at Mount Mackenzie during the quarter?

QMines drilled 6,922m during the quarter across North Knoll, the Western Extension and Vein 355. By 31 March, total cumulative Mount Mackenzie drilling reached 6,684.5m RC and 3,010.3m diamond for a total of 9,694.8m drilled.

What is the significance of the five new targets identified at Mount Mackenzie?

Reprocessed IP data identified five undrilled near surface targets across a 1.2km x 750m footprint, including two annular lithocap style centres and three sulphide bearing structural conduit targets adjacent to the North Knoll and South West Slopes deposits. This demonstrates significant growth potential beyond the current known deposits.

How did the Develin Creek resource change this quarter?

The Develin Creek Mineral Resource estimate increased by 14% to 4.70Mt @ 0.94% Cu, 1.00% Zn, 0.15g/t Au and 5.7g/t Ag at a 0.30% Cu cut off. The update increased Indicated Resources to 4.22Mt @ 0.98% Cu and 1.08% Zn, now representing approximately 90% of the total resource.

What funding did QMines secure and how does this help the company?

Subsequent to quarter end, QMines announced a strategic $15 million funding package with the Queensland Investment Corporation (QIC) Critical Minerals and Battery Technology Fund. The transaction comprises a combination of equity investment and royalty funding and is expected to fully fund QMines through completion of the DFS and toward FID for the Mt Chalmers Copper and Gold Project.

What progress was made on the Mt Chalmers Definitive Feasibility Study?

The Mt Chalmers DFS commenced with multiple active workstreams progressing including geotechnical drilling, environmental baseline studies, mineragraphy and improved geological modelling activities. Geotechnical drilling commenced during March, with packer testing and downhole data collection underway, and four groundwater monitoring bores were completed.
