True North Copper Limited (ASX: TNC) (TNC or the Company) is pleased to announce an update to the copper- silver Mineral Resource at Vero, part of its Mt Oxide Project in Queensland.
HIGHLIGHTS
- True North’s updated Copper-Silver Mineral Resource Estimate (MRE) for its 100%-owned Vero deposit, reported in accordance with the JORC 2012, contains 15.03Mt at 1.46% Cu & 10.59g/t Ag for a contained 220kt Cu & 5.13Moz Ag (Indicated and Inferred, refer to Table 1).
- Vero’s updated Resource delivers a 20% increase in silver ounces, demonstrating the potential for Vero to deliver a significant sliver co-product in addition to copper.
- Reassessing underground mine voids and introduction of improved geological deposit model has resulted in a minimal 3% decrease in copper metal tonnes, delivering further confidence in the resource integrity following 2023 confirmatory drilling.
- TNC used revised geotechnical and metallurgical studies in the updated geological analysis for the MRE and will also inform possible mining options for the Vero deposit.
- MIMDAS IP program at Mt Oxide is progressing well with the line at Camp Gossans complete. MIMDAS is now being acquired over the Vero deposit aiming to identify drill target for resource expansion at depth.

COMMENT
True North Copper’s CEO and MD Bevan Jones, said:
“We are pleased to deliver an update to Vero’s contained resources, particularly an increase in silver, a metal which is currently seeing a supply-demand imbalance though demand in solar and other technology applications. This updated Resource also provides greater confidence in the deposit, following TNC’s first program of confirmatory drilling and a substantially updated geological model, which incorporates historic resource depletion by previous mining.
“We see exploration upside within reach of shallow drilling at Ivena, north of the Resource, and along a 10km section of the Dorman fault where we are actively exploring for satellite zones of mineralisation with the MIMDAS crew onsite completing the line at Camp Gossans. The survey team are now moving to the north to acquire the line over the Vero Deposits with the aim to identify drill targets at depth below the current resource.
We look forward to providing an update on our progress on these Mt Oxide exploration activities over the coming months.”

Abitibi Metals Identifies New Drill Targets from Gravity Survey
Abitibi Metals Corp. (CSE:AMQ) (OTCQB:AMQFF) (FSE:FW0) ("Abitibi" or the "Company") is pleased to announce the identification of new exploration targets at the B26 Project, achieved through the application of advanced gravimetric surveying. The Company recently received an updated inversion model, which has revealed high-priority exploration targets. These targets present opportunities for exploration and resource development, including: 1) better defining the B26 signature along strike, and 2) testing a high priority anomaly at the down-dip extension of the B26 Deposit. On November 16th, 2023, the Company entered into an option agreement on the B26 Polymetallic Deposit to earn 80% over 7 years from SOQUEM Inc. ("SOQUEM"), a subsidiary of Investissement Québec (see news release dated November 16, 2023).
Highlights:
- Prospective Down-Dip Anomaly: A new excess mass has been identified at a depth of 800m on the eastern side of the B26 Deposit, indicating strong sulfide and copper-zinc mineralization potential in an area outside the current resource. This new target has a diameter of 400–500 metres, with nearby drill holes containing semi-massive mineralization.
- Along-Strike Targets: Eight shallow targets have been identified along-strike of B26, extending up to 6-km west. These targets are within the 8.3 km property-wide contact that hosts the B26 Deposit and where there has been limited historical exploration.
- Northwest Targets: Four targets were identified to the northwest of B26, providing high-priority exploration targets along trend with the Selbaie Mine.
- Applying New Geophysical Techniques: Historical electrical surveys failed to differentiate mineralization from pyritic/graphitic rock. However, new data processing tools and down hole gravity surveys using Gravilog improve target discrimination at depth. Abitibi aims to integrate these with other tailored geophysical methods to better target the high-grade expansion of B26.
"The identification of these new high-priority targets at B26 marks a significant advancement in our exploration strategy," said Jonathon Deluce & CEO of Abitibi Metals. "The application of advanced gravimetric surveying and reinterpretation of historical data has allowed us to refine our targeting and enhance our understanding of the deposit and property wide potential. The down-dip anomaly, along with multiple along-strike and northwest targets, presents a compelling opportunity for resource expansion and discovery in previously underexplored areas. We are committed to leveraging cutting-edge geophysical techniques to unlock the full potential of B26 and drive long-term value for our shareholders."

Figure 2: Gravity Anomaly 5513300N (CNW Group/Abitibi Metals Corp.)
Figure 3: Gravity Anomaly 5513400N (CNW Group/Abitibi Metals Corp.)
A strong gravity contrast was modeled along the down-dip extension of the B26 deposit that was based on: 1) Soquem's 2017 Gravilog survey, 2) density measurements from drill holes, and 3) a 2024 surface gravimetry survey. Abitibi Geophysics reinterpreted the Gravilog data with new inversion software that takes into account the variation in gravity along the drill holes. The interpretation was developed collaboratively by Abitibi Geophysics and Abitibi Metals geologists, to ensure that each anomaly corresponded to an area that was prospective geologically.
The survey was composed of 1466 stations distributed on 26 lines; 250 to 500 metres spaced, completed in June 2024 by Geophysics TMC. Abitibi Geophysics personnel conducted a survey analysis and reinterpreted the borehole Gravilog data, combining it with the surface gravity lines survey.
Down Dip Target
The modeled target has a diameter of 400–500 metres. Surrounding drill holes, such as 1274-17-255 W1, indicate strong sulfide content, with semi-massive intervals hosting copper-zinc mineralization over metric intervals near the upper limit of the gravity anomaly. Only the boundaries of this new target were covered with limited drilling and can be considered open. The majority of the target is located outside of the interpreted outline of the mineralized system and elevated copper equivalent grades have been observed in historical drill assays on the target's boundary. Highlights include: 1) 1.2% CuEQ over 10.5m starting from 767.1m (1274-16-231), 2) 2.4% CuEQ over 11.8m starting from 1,111m including 36.5% CuEQ over 0.7m (1274-16-239), and 3) 2.7% CuEQ over 10.5m starting from 990m including 15.1% CuEQ over 1.1m (1274-17-248) (see figures 2 and 3).
Along Strike and Northwest Targets
TMC Geophysics discriminated a series of positive gravity anomalies along strike, expending up to 6km west of B26 and also north-west of the deposit. The targets consist of vertical lenses with varying dimensions, as defined by the inversion model generated by Seequent Voxi-GRAV-3D Software. These targets were identified based on modeled density contrasts, including a 3 km-long elongated low density contrast aligned with the B26 system, as well as additional anomalies in the central area of the property, likely associated with sulfide-bearing volcanic contacts. A modeled low gravity anomaly may correspond to the contact at depth with the Brouillan intrusion. Abitibi Geophysics generated a model that focused on a gravity contrast of a few hundred meters south of the B26 zone. The inversion model was based on density measurements taken on drill core.
The surface gravity anomaly revealed a continuous gravimetry contrast covering the entire strike length of the Enjalran-Brouillan contact south of the B26 mineralized trend. The inversion model showed eight distinct high gravity anomalies. The eastern one corresponds to the position of the B26 mineralization. Going westward, the environment north of anomalies are not drill tested. Different interpretations suggest the anomalies may be related to the presence of mafic dyke swarms observed in the hanging wall of the VMS mineralization. AMQ intends to use these anomalies as a foundation for exploration, investigating their potential as proximity indicators for locating additional polymetallic mineralized systems.
These geophysical methods, integrated into the exploration strategy to locate additional mineralization at depth and along strike, are continuously evolving. Historically, the deposit was investigated using electrical methods, which were unable to effectively distinguish and clearly highlight the polymetallic stringers and vein systems from the strongly pyritic and locally graphitic units surrounding the deposit. By incorporating new analysis tools, the downhole gravity survey using system will enable Abitibi's technical team to better discriminate targets at depth with much greater detail. Moving forward, the Company will couple this approach with other geophysical methods that are specifically tailored to the B26 deposit and its unique geological characteristics.
Note 1: Targets identified consist of vertical lenses with varying dimensions, with a density of 3.0 g/cm³, and the inversion was based on deviations from a 2.67 g/cm³ density model. Shallow targets were identified based on a density contrast of up to 0.15 g/cm³.The local density model outlined below in figures 2 and 3 was established for the B26 deposit based on surface gravity. A depth response calculated using Gravilog measurements revealed a positive gravity contrast of 0.5 mGal, centered on section 652700 at approximately 800 metres vertical depth. |

Updated Maroochydore Copper-Cobalt Resource Demonstrates Large Copper Sulphide System with 1.6Mt Contained Copper
Highlights of the Resource Upgrade include:
- Inferred resources of 370,800,000 tonnes at 0.43% Cu and 227 ppm Co for 1,595,000 contained copper and 84,000 tonnes contained cobalt at 0.25% Cu cut-off grade.
- Higher-grade zone contained within the inferred resource of 106,300,000 tonnes at 0.67% Cu and 308 ppm Co for 712,000 tonnes contained copper and 33,000 tonnes contained cobalt at 0.45% Cu cutoff grade.
- Sedimentary copper mineralisation style demonstrating significant continuity of mineralisation and resource scale - similar geology to nearby Nifty Copper Complex.
- Higher grade domain will be further studied as satellite feed operation to Cyprium’s nearby Nifty mill and concentrator in the Paterson district.
Cyprium Executive Chair Matt Fifield commented:“Maroochydore has seen little attention over the last decade - previous work was focused on the near-surface copper oxide mineralization. Cyprium recognised the same sedimentary copper mineralisation style that we have at Nifty and turned our attention to the potential of the copper sulphide resource. We remodelled the historic resource from first principles and included an additional 19,456 meters of core and RC drilling that was available.
The results are clear – Maroochydore is a very large, near-surface sulphide resource with a higher- grade zone that has high potential to be a medium-term expansion project for Cyprium. An important moment for Cyprium, and a potential meaningful source of Australian copper and cobalt.”

Updated Resource Model Shows Near-Surface, Flat-lying Sedimentary Copper System
Maroochydore is a sediment-hosted deposit type located in the Paterson region of Western Australia. The project is 81km by air and ~100km by unsealed road from Cyprium’s Nifty Copper Complex.
Figure 1: Maroochydore general location and regional infrastructure
Stratigraphy at Maroochydore is part of the Broadhurst Formation (Yeneena Group) similar to the nearby Nifty Copper Complex.
The deposit is a mixture of oxide/supergene and primary sulphides. The upper resources are dominated by oxide and transitional materials hosted in the 50 to 100m thick mineralised horizon consisting of carbonaceous shales and recrystalised dolostones.
The structural framework that hosts the mineralised sequence is less restricted than what is found at Nifty, which leads to Maroochydore’s more extensive and diffuse mineralisation system. Current mineralised material is defined over a strike length of ~7km and is shallow, with cover varying from 20m depth at the south-eastern end to 80m depth at the north-western end, and relatively flat lying.
