True North Copper

What True North Copper does

True North Copper Limited (ASX: TNC, formerly Duke Exploration Limited following a June 2023 reverse-takeover merger) is an Australian copper-focused exploration and development company headquartered at the Great Australia Mine site in Cloncurry, Northwest Queensland. The company holds a 100%-owned portfolio of assets in the Mt Isa Inlier, a world-class copper province, organised around a three-stage strategy: DEVELOP the Cloncurry Copper Project, GROW the Mt Oxide Project, and DISCOVER Tier 1 regional copper-gold targets. Its defined JORC 2012 resources include 101.25 kt Cu, 76.62 koz Au and 1.86 kt Co at Cloncurry (95% Indicated) and 220 kt Cu, 5.13 Moz Ag and 21.2 kt Co at Mt Oxide, where the 2025 Aquila discovery returned intercepts including 7m at 7.9% copper within a broader 59m zone averaging 1.77% copper, and the mineralised trend has since been extended to 900m+ strike length.

The company's core technology is a systematic, boots-on-ground exploration methodology combining mapping, geochemistry and Induced Polarisation geophysics to identify and rank drill-ready targets, including gossanous breccias with anomalous copper and pathfinder elements. The Cloncurry Operations Hub includes a refurbished solvent extraction (SX) plant, flotation plant, crusher, heap leach and tailings facilities (currently in care and maintenance), and the Mt Oxide tenement is 100km from the Mt Isa Copper Smelter and 40km by road from 29Metals' Capricorn Copper processing plant, giving the assets a strategic distribution advantage in a tier-1 mining jurisdiction.

True North Copper is pre-revenue: the company is in exploration and pre-feasibility stage, with the Cloncurry Pre-Feasibility Study commenced in late 2025 and Mt Oxide drilling restarted in April 2026. Once in production, revenue is expected to come from direct sales of copper concentrate, cathode copper, gold, silver and cobalt to nearby smelters and processors (Mt Isa Copper Smelter and 29Metals' Capricorn Copper). Capital is currently sourced from equity raises (e.g., a December 2024 share purchase plan targeting up to A$5M) and non-dilutive Queensland Government grants (CEI and CDP programmes). The customer set, offtake structure and pricing are not yet disclosed.

Core offering

True North Copper is an Australian copper-focused exploration and development company advancing 100%-owned copper-gold-cobalt-silver assets in the Mt Isa Inlier of Northwest Queensland. Its portfolio includes the Cloncurry Copper Project (centered on the Great Australia Mine Complex with existing SX plant, flotation plant, crusher, heap leach, and tailings facilities) and the Mt Oxide Project (containing the Vero Resource and the Aquila discovery). The company sells or plans to sell copper concentrate, cathode copper, gold, silver, and cobalt products to downstream smelters and processing facilities.

Product overview

True North Copper is an Australian copper exploration and mining company advancing a portfolio of 100%-owned assets in the Mt Isa region of northwest Queensland. The company's portfolio consists of two major projects: the Cloncurry Copper Project (DEVELOP stage) focused on copper-gold-cobalt extraction with associated processing infrastructure including SX and flotation plants, and the Mt Oxide Project (GROW stage) targeting copper-cobalt-silver mineralisation including the Vero Resource. The company also pursues regional target discovery (DISCOVER stage) for additional copper-gold deposits. The company's three-stage growth strategy encompasses developing the Cloncurry Copper Project, growing the Mt Oxide Project, and discovering Tier 1 regional targets.

• Regeneration EnterprisescoreStrategic or Co-development Partner · 24 February 2026Partnership to collaborate on a Queensland Government Collaborative Development Programme grant of approximately AUD $440,000 to assess legacy mine waste materials at TNC's Mt Oxide copper project. The programme will evaluate potential to reprocess historic waste streams through drill sampling, assay, and metallurgical testing to determine whether residual metals can be commercially recovered while supporting environmental rehabilitation outcomes. This non-dilutive funding adds an additional source of value to the company's existing resource base.

Direct peers

• 29Metals: 29Metals operates the Capricorn Copper mine in Queensland's Mt Isa region, ~40km from TNC's Mt Oxide project. It is the most direct operational peer given its copper-cobalt focus, proximity to TNC's assets, and use of the same regional infrastructure and labor pool.
• Aeris Resources: Aeris Resources is an ASX-listed copper-gold producer with operations in Queensland (including the Tritton and Jaguar operations in the broader region). It is a direct peer given its similar copper-gold focus, ASX listing, mid-junior size, and exposure to Australian copper mining.
• KGL Resources: KGL Resources is an ASX-listed copper developer advancing the Jervois copper project in the Northern Territory. It is a direct peer given its similar copper-focused developer profile, ASX listing, pre-production stage, and comparable size to TNC.
• Carnaby Resources: Carnaby Resources is an ASX-listed copper-gold explorer with assets in the Mt Isa region of Queensland. It is a direct peer given its geographic overlap with TNC in the Mt Isa Inlier, copper-gold exploration focus, and junior developer status.
• Hammer Metals: Hammer Metals is an ASX-listed explorer with copper-gold and critical minerals projects in the Mt Isa region of Queensland. It is a direct peer given its regional overlap with TNC and junior copper-gold exploration profile.

Broad incumbents

• Sandfire Resources: Sandfire Resources (now part of the Sandfire/Aeris combination) is an established mid-tier Australian copper producer with the DeGrussa and Motheo operations. It is a broad incumbent peer given its larger scale, copper focus, and ASX listing alongside TNC.
• OZ Minerals (BHP): OZ Minerals (acquired by BHP) operated the Prominent Hill copper-gold mine in South Australia and was a key employer of TNC's senior leadership. It is a broad incumbent peer given its copper-gold focus and major-miner status that anchors the broader Australian copper sector where TNC operates.
• Capstone Copper: Capstone Copper is a TSX-listed mid-tier copper producer with operations across the Americas. It is a broad incumbent peer given its pure-play copper focus and mid-tier scale, providing a useful public-market comparable for TNC's copper valuation.

Emerging players

• White Rock Minerals: White Rock Minerals is an ASX-listed junior with copper-gold-silver exploration assets including the Red Mountain project. It is an emerging player peer given its similar junior copper-gold exploration focus and ASX listing, though its primary assets are in different jurisdictions.
• Emmerson Resources: Emmerson Resources is an ASX-listed gold-copper explorer focused on the Tennant Creek region of the Northern Territory. It is an emerging player peer given its similar junior exploration profile and gold-copper focus, providing a relevant comparable for TNC's exploration-stage valuation.
