- Wallace North and GAM Ore Reserves combine to form the CCP. Full details of the proposed Mining Restart Plan with project economics, assumptions and other key criteria will be released to the ASX and shareholders, in the next two weeks.
COMMENT
True North Copper’s Managing Director, Marty Costello said:
The fully permitted Wallace North Project is currently one of four open pits that will be mined as part of our Cloncurry Copper Project. We plan to schedule the Wallace North open pit as the first to be mined.
Our resource infill drilling and reconciliation confirms high-grade copper and gold. Our confidence in the Wallace North open pit extends beyond its initial ore reserve. The iterative nature of our mine design process allows us to continuously refine our understanding of the ore body. As we advance our operations and gather more data, we anticipate that future iterations of the mine design could reveal additional ore reserves, enhancing the project's overall value and extending its life.
We believe scheduling the Wallace North open-pit first, allows for early-life free cash flows, and minimises working capital and payback periods.
We are excited to shortly present to our shareholders and the market our Cloncurry Copper Project mining restart start plan.

- Oxide ore from Wallace North will be hauled by road train to TNC’s GAM Heap Leach Operations.
- Sulphide ore will be hauled to a nearby concentrator for toll treatment as part of TNC’s toll-milling agreement with Glencore2.
- Wallace North will be mined from surface with minimal topsoil and waste stripping required. Ore will be stacked at the pit, stockpiled and then reloaded to road trains for transport. Crushing will be completed at the CCP Operations Hub and at the toll treatment facility.
Wallace North Ore Reserve
Wallace North is located 37km from the CCP Operations Hub on two granted mining leases ML 2695 and ML 90236. Toll treating facilities are located less than 80km north by road.
TNC recently announced a combined Indicated and Inferred Mineral Resource Estimate at Wallace North of 1.59Mt @ 1.31% Cu and 0.78g/t Au for 23.5kt of copper and 44.8koz of gold4. The January 2024 MRE by Encompass Mining Solutions Pty Ltd (Encompass) following the inclusion of advanced grade control and re-assay data from diamond core drilling, which resulted in a 300% improvement to Indicated Resources4.
Previous mining at Wallace South has provided information on the geology and geotechnical conditions for mining. Global Ore Discovery Pty Ltd and Resolve Mining Solutions Consultants in collaboration with TNC geologists, have reviewed historic and recent drilling, including advanced grade control. Environmental Authorities, land holder and traditional owner agreements have been active for a number of years.
TNC engaged MEC to complete the ore reserve estimation for the Wallace North deposit, based on the 2024 Mineral Resource Estimate4. As part of the reserve estimation, MEC conducted an open pit optimisation, mining schedule and haulage model as part of a life of mine plan consistent with a pre-feasibility level of study. A financial model was developed by MEC based on the outputs of the mining schedule and haulage model to determine the economic viability of the deposit. Operational costs were developed for drill and blast, mining and processing based on TNC's contracts and quotes. The Indicated Resources contained within the mine design have been classified as Probable Reserves.
The optimisation study and accompanying assumptions including scheduling, haulage and financial modelling have been conducted to the accuracy level of a pre-feasibility study (+/-30%).
Financial modelling by MEC based on the outputs of the mining schedule and utilising slightly different parameters which were generally more conservative to the optimisation, delivered a positive NPV over an 18-month period, confirming the viability of the project.
The JORC 2012 Maiden Probable Ore Reserve estimate for the Wallace North project of 0.7Mt @ 1.01% Cu and 0.46g/t Au containing 6.8kt Cu and 10.0koz Au (Table 1), is a substantive addition to the total reserves for the Cloncurry Copper Project.
The ore reserve uses metal prices of sulphide at US$8,500/t, copper sulphate offtake pricing and applied premiums are used at US$9,350/t; Gold from the sulphide plant US$1,850 and exchange rate is set at AUD:USD 0.7.

Nobel Resources Announces Additional Results at the Cuprita Project, Atacama Region, Chile
Nobel Resources Corp. (TSX – V: NBLC) (the “Company” or “Nobel”) is pleased to provide an update on its ongoing exploration at the Cuprita Project (the “Project” or “Cuprita”) in Atacama Region, Chile. Following the recent identification by Nobel geologists of a leach cap with characteristics strongly associated with porphyry copper-(gold) deposits in the region at Cuprita, including associated highly anomalous copper in soils and bedrock, the Company has additionally confirmed:
- the existence of an IP chargeability and resistivity anomaly typical of porphyry copper deposits in the region; and
- the presence of highly anomalous copper chip samples from outcrops associated with the leach cap.
The geological features being identified by Nobel field work at Cuprita demonstrates the Project is highly prospective.
According to Vern Arseneau, COO of Nobel, “After only a few short weeks in the field, Nobel Geologists have identified key characteristics of a shallow mineralized porphyry system at Cuprita. The leach cap, IP anomaly, significant copper bearing rock chips and the copper in soil anomaly are all located adjacent to a ground magnetic low. These traits are situated near the intersection of a major north-northeast striking fault structure with numerous northwest striking quartz veins with copper oxides. Intersecting major faults is a common, if not essential, structural control for the emplacement of copper-gold porphyries in the region (Figure 3). This is essentially the complete suite of important indicators used when identifying productive porphyry copper systems, combined with a leach cap in one of the most important porphyry copper belts globally indicate excellent potential for a mineralized porphyry deposit at the Cuprita project.”
The IP survey was carried out by Argali Geophysical SA during November 2018 and consisted of three E-W lines across the area of the recently identified leach cap. Survey parameters were 100m spaced dipoles with an estimated depth penetration of 700m at N=27. The top of the IP anomaly, based on this data, is estimated to be approximately 200meters below surface. (Figure 3; line 7055700N). All three lines exhibit a similar chargeability/resistivity response and the anomaly remains open to the North and South.
The chargeability anomalies from 7 to 9 mV/V are in line with many of the porphyry copper deposits near Inca de Oro which are notoriously low in pyrite and therefore in chargeability. Chargeability of less than 10 mV/V has been observed at many deposits local to Cuprita. Similarly, field observations by Nobel geologists have also confirmed the general lack of pyrite in altered rocks at Cuprita.
Rock chip sampling of mineralized structures associated with the leach cap, anomalous soil samples and the ground magnetic anomalies returned highly anomalous copper values ranging from 0.25 to 3.46% Cu. Many of the rock samples contain remnant copper sulfides, such as Chalcocite, Chalcopyrite and locally Bornite (Figure 1). Additionally, a sample taken 500m to the northeast, where QZ vein stockwork with disseminated chrysocolla outcrops with a grade of 2.06% Cu (Figure 2) signifying the potential for a large extensive system.

Figure 2: Sample of copper-rich stockwork of quartz and chrysocolla grading 2.06% copper from 500 meters northeast of previous sample.
According to Larry Guy, CEO, “Nobel geologists believe that this newly identified geological / geochemical evidence along with the geophysical compilation points to potential for a large mineralized porphyry at shallow depth covering the area between the anomalous soil results to the South and extending more than 2 kilometers North to the previously reported ground magnetic lows. (Figures 3 and 4; map and cross section and Figure 5 conceptual geological model).
Geologically, Cuprita is part of the Metallogenic Paleocene Porphyry Copper Belt that hosts several major porphyry copper deposits, such as El Salvador, Cerro Colorado, Spence, Sierra Gorda, Fortuna, as well as several gold deposits. Recent field work at Cuprita has focused the targeting for forthcoming drill programs.

Empire Metals Limited Announces Completion of MRE Drilling Campaign
- 180 drill holes completed at the Thomas prospect, comprising:
- 140 Air Core ('AC') drill holes for a total of 6,360 metres;
- 40 Reverse Circulation ('RC') drill holes for a total of 3,776 metres;
- Total metres drilled: 10,136
- Drilling was conducted on a systematic 400m by 200m grid covering over 1,352 hectares and was designed to support the initial MRE as well as providing key data for economic evaluation studies.
- The Thomas Prospect was selected as the basis for the maiden MRE due to the extensive, thick and high-grade titanium mineralisation hosted within the broad, in-situ weathered zone.
- This campaign marks a major milestone in the development of Pitfield, laying the foundation for a globally significant MRE and enabling the identification of near-surface, high grade zones to support the development of mine planning and ore scheduling as part of upcoming economic evaluation studies.
Shaun Bunn, Managing Director, said: "We are very pleased to have completed this important drilling campaign on time, on budget and without safety incident. With drilling now complete, our focus turns to resource modelling and progressing Pitfield towards its maiden Mineral Resource Estimate, which is a key milestone as we look to bring this globally significant titanium project to commercialisation, maintaining the ambitious development schedule we have delivered over the past two years."
MRE Drilling Programme
With the completion of the current drill campaign, the largest undertaken by the Company to date, total drilling at Pitfield has now surpassed 32,000m across 382 holes, providing a robust foundation for geological modelling, resource definition (refer Figure 1) and initial economic evaluation work.
Since commencing the maiden drilling campaign at Pitfield on 27 March 2023 Empire has completed 382 drill holes for a total 32,265 metres comprising:
- 17 Diamond drill holes for 2,704 m
- 140 RC drill holes for 18,764 m
- 225 AC drill holes for 10,797 m.

May-June 2025 Campaign
The location and spacing of the current RC and AC drillholes were designed, with the input of mineral resource consultants Snowden-Optiro, to provide the necessary drill assay data density to allow the preparation of an MRE at the Thomas Prospect.
The completed drill campaign consisted of 140 AC drillholes, on a 400 x 200m drillhole-spaced grid with an average forecast depth of 45.4m, for a total of 6,360 metres, and 40 RC drillholes within the AC drilling grid, to an average depth of 94.4m, for a total of 3,776 metres. The overall drillhole grid extends 5.2km by 2.6km and totals an area of 1,352 hectares (refer Figure 2).
Figure 2. RC and AC drill hole collar locations within the Thomas Prospect priority area.
During the campaign all drill holes were subsampled on a 2m interval, resulting in over 5,000 drill samples being collected, logged by our on-site team of geologists and then prepared for shipment to Intertek's Perth based analytical laboratory. As of the end of June all drill hole and QA/QC samples have been delivered to Intertek for geochemical analysis and assaying.

About Empire Metals Limited
Empire Metals is an AIM-listed and OTCQB-traded exploration and resource development company (LON:EEE) with a primary focus on developing Pitfield, an emerging giant titanium project in Western Australia.
The high-grade titanium discovery at Pitfield is of unprecedented scale, with airborne surveys identifying a massive, coincident gravity and magnetics anomaly extending over 40km by 8km by 5km deep. Drill results have indicated excellent continuity in grades and consistency of the mineralised beds and confirm that the sandstone beds hold the higher-grade titanium dioxide (TiO₂) values within the interbedded succession of sandstones, siltstones and conglomerates. The Company is focused on two key prospects (Cosgrove and Thomas), which have been identified as having thick, high-grade, near-surface, bedded TiO₂ mineralisation, each being over 7km in strike length.
An Exploration Target* for Pitfield was declared in 2024, covering the Thomas and Cosgrove mineral prospects, and was estimated to contain between 26.4 to 32.2 billion tonnes with a grade range of 4.5 to 5.5% TiO2. Included within the total Exploration Target* is a subset that covers the weathered sandstone zone, which extends from surface to an average vertical depth of 30m to 40m and is estimated to contain between 4.0 to 4.9 billion tonnes with a grade range of 4.8 to 5.9% TiO2.
The Exploration Target* covers an area less than 20% of the overall mineral system at Pitfield which demonstrates the potential for significant further upside.
Empire is now accelerating the economic development of Pitfield, with a vision to produce a high-value titanium metal or pigment quality product at Pitfield, to realise the full value potential of this exceptional deposit.
The Company also has two further exploration projects in Australia; the Eclipse Project and the Walton Project in Western Australia, in addition to three precious metals projects located in a historically high-grade gold producing region of Austria.
*The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Loyal to Acquire the High-Grade Highway Reward Copper Gold Mine
Key Highlights
- Loyal secures binding option to acquire the Highway Reward Copper Gold Mine in Queensland, Australia - one of the world’s highest-grade copper mines, with past production totalling 3.65Mt at 5.7% Cu and 260kt at 4.5 g/t Au.
- The acquisition is the first step in Loyal’s 2025 Strategic Plan to broaden its critical minerals portfolio into copper.
- No exploration has been conducted on the granted mining leases since operations ceased in July 2005 despite a ~680% increase in copper prices and a ~1,256% increase in gold prices since the 1997 feasibility study.
- Significant increase in copper and gold prices, combined with the previous exclusion of gold in sulphides from the mine plan, highlights the enhanced remnant copper-gold potential.
- Exploration potential for new discoveries both along strike and at depth, as previous mining only reached depths of 220 metres for open pit and 390 metres for underground operations, with limited exploration beyond mined zones.
- With $4.4 million in funding, Loyal is well-positioned to revisit the high-grade Highway Reward Copper Gold Mine by deploying modern exploration techniques. With global initiatives to enhance energy grids and no USA tariffs on Australian copper, the outlook for copper is strong and unencumbered.
Loyal‘s Managing Director, Mr. Adam Ritchie, commented:
"We are thrilled to secure this incredibly rare opportunity for our current and future Loyal investors. The Highway Reward Copper Gold Mine, considered one of the highest-grade copper mines in the world, is now primed for a revisit after 20 years of dormancy.
The granted mining leases of the Highway Reward mine provide an amazing speed to market opportunity - especially when both copper and gold are near all-time highs. The short-term and long-term opportunities at Highway Reward are exciting, considering the significant growth in commodity prices since the 1997 feasibility study. Copper is driving our electric future and gold continues to play an important role in our global economy.
Whilst a lot has changed in the past 28 years, the unwavering demand for copper and gold has only intensified. This is truly an amazing opportunity to unlock and showcase the immense potential of this forgotten mine. With modern technology and innovative mining techniques, we believe the Highway Reward Copper Gold Mine will provide exceptional value and returns to our Loyal shareholders."
Figure 1 Highway Reward Copper Gold Mine: Located 37 km south of Charters Towers within the Mount Windsor Volcanic Belt. Accessible via an all-weather highway, 172 km from the Port of Townsville, Queensland, Australia.
The Highway Reward Copper Gold Mine is located only 37 km from the active mining town of Charters Towers in Queensland, Australia, within the Mount Windsor Volcanic Belt. This area is renowned for its rich history in copper and gold mining, with strong social license support for mining activities. It features large-scale mining operations such as, Newmont’s 3.2 Moz Mt Leyshon gold mine and Yuxin Holding’s 3.4 Moz Pajingo gold mine. The region is close to the polymetallic, Thalanga Processing Plant and the Mount Carlton Processing Plant, with road and rail to Glencore’s Mount Isa copper hub, Townsville copper refinery and the Port of Townsville.
With the growth in commodity prices and advancements in exploration and mining technologies, the potential for remnant copper-gold mining has significantly improved. Previous mining operations targeted copper within chalcopyrite, while gold associated with both chalcopyrite and pyrite was excluded from the mine plan. With lower copper equivalent cut-off grades (copper & gold), higher continuity of copper-gold can be drill tested to demonstrate the reasonable prospects for eventual economic extraction and mineral resource potential.
Graph 1: Highway Reward Copper Gold Mine - mining ceased in July 2005: 28 Years of Commodity Growth
Significant potential will be assessed and areas tested for copper-gold extensions to subvertical trends, that may exist below current mining levels at the Highway Reward Copper-Gold Mine. The previously mined, copper-gold rich pipes will also be assessed for drill testing along strike (Figure 2). Previous mining and surface mapping geological observations illustrate that high- grade copper-gold pipes have been identified in dacite, rhyolite, and volcaniclastic host rocks, therefore strong prospectivity exists for discovering additional pipes beyond the historically mined zones in all rock types on the property, except recent overlying sediments that conceal the basement host rocks (Figure 2). No modern advanced geophysical techniques or data processing methods have yet been applied to assess this potential.
