True North Copper Expands Discovery Potential at Aquila
True North Copper Limited (ASX:TNC) has significantly expanded the footprint of its Aquila copper-cobalt-silver discovery at the Mt Oxide Project in Queensland, with a new IP geophysical survey revealing multiple high-priority drill targets across a potential multi-kilometer system.
Geophysical Survey Transforms Understanding of Aquila's Scale
The recently completed infill and extension Induced Polarisation (IP) survey has dramatically extended the Aquila geophysical trend from just 250m to over 1.3km in strike length. This expansion coincides with surface copper-cobalt-silver mineralisation and builds on the company's successful drilling program that previously delivered impressive intercepts including:
- 145m @ 0.75% Cu, 0.12% Co and 2.9 g/t Ag from 28m, including 53m @ 1.18% Cu, 0.13% Co, 3.6 g/t Ag from 86m (MOX232)
- 30m @ 2.45% Cu, 0.02% Co, 6.2 g/t Ag from 20m (MOX233)
- 16m @ 1.25% Cu, 0.01% Co, 1.9 g/t Ag from 163m (MOX231)
What began as a single anomaly with limited strike extent has transformed into a potential multi-kilometer copper-cobalt-silver system with three distinct mineralised trends: Aquila, Apollo, and Acanthis.
Three Distinct Mineralised Trends Identified
The IP survey has delineated three parallel, north-south trending zones of high-order geophysical anomalies:
-
Aquila Trend: Extended to 1,330m length with increasing intensity from south to north, featuring coincident high chargeability (+20 mV/V) and conductivity (+10.0 mS/m) anomalies. Notably, the trend connects to the historical Mt Gordon Mine, which produced copper ore averaging 11% grade in the 1950s-60s.
-
Apollo Trend: A 1,360m long high-order anomaly running parallel to the western margin of the Mt Gordon fault zone, with chargeability up to 25 mV/V. The southern section includes a 250m anomaly near a historic copper oxide mine where channel sampling has yielded 3.6m @ 0.87% Cu.
-
Acanthis Trend: A 770m long anomaly approximately 110m east of the Aquila Trend that may merge with the Aquila Discovery anomaly to the south.
Strategic Location in an Emerging Copper Hub
The Aquila Prospect sits just 4km from True North's Vero copper-silver-cobalt Resource (15.03Mt @ 1.46% Cu, 10.59g/t Ag; 9.15Mt @ 0.23% Co), reinforcing Mt Oxide as a developing multi-deposit copper-cobalt-silver hub.
"Our recent IP survey has significantly expanded our understanding of the Aquila mineralised system. What began as a single anomaly with limited strike extents is now emerging as a potential multi-kilometre-scale copper-cobalt-silver system," commented Managing Director Bevan Jones.
Understanding Induced Polarisation Surveys
Induced Polarisation (IP) is a geophysical technique widely used in mineral exploration to detect disseminated sulphide mineralisation that may host valuable metals like copper. The method works by measuring how the ground "charges up" when an electrical current is passed through it.
In simple terms, when metallic minerals like copper sulphides are present in the ground, they act like tiny capacitors that store electrical charge. IP surveys measure this charging effect (chargeability) and the ground's ability to conduct electricity (conductivity). Higher chargeability and conductivity readings often indicate areas with higher concentrations of sulphide minerals, which can host copper, cobalt, and other metals.
The coincident high chargeability and conductivity anomalies identified at Aquila are particularly encouraging as they suggest areas with potentially significant sulphide mineralisation – exactly what explorers look for when hunting for economic copper deposits.
Aggressive Exploration Program Underway
True North has already completed first-pass drilling at the southern end of the Apollo Trend and is finalising plans for an aggressive follow-up program across all newly defined extensions. The company's systematic, data-driven approach has proven its value at Aquila, with a clear focus on testing multiple new targets along strike and at depth.
Key upcoming milestones include:
- Results from 5 holes (1,350m) drilled in the southern Apollo Trend expected in early November 2025
- Step-out drilling north and south of the Aquila Discovery zone
- A high-resolution drone magnetic survey across the broader Mt Gordon Fault Zone
Why Investors Should Watch True North Copper
True North Copper presents a compelling investment opportunity for several reasons:
-
Proven Targeting Methodology: The company's exploration approach has already delivered significant copper-cobalt-silver mineralisation at Aquila, validating its targeting methodology.
-
Multiple Growth Opportunities: With three distinct mineralised trends now identified, True North has a pipeline of high-quality targets that could significantly expand its resource base.
-
Strategic Location: The Mt Oxide Project is situated in the prolific Mt Isa Inlier, a world-class metallogenic province known for major copper deposits.
-
Existing Resource Base: The nearby Vero deposit gives True North a solid foundation upon which to build additional resources at Aquila and other prospects.
-
Exposure to Critical Minerals: The copper-cobalt-silver combination provides exposure to both traditional industrial metals and battery metals critical for the clean energy transition.
As drilling continues and results flow in, True North Copper is well-positioned to deliver resource growth and create significant value across the Mt Oxide Project, making it a company that resource investors should follow closely in the coming months.
