How Aruma’s EM Survey Unlocked New Depths at Tillex Copper-Silver Project
Aruma Resources’ recent electromagnetic survey at the Tillex Project in Ontario reveals significant extensions to known copper-silver mineralisation, setting the stage for imminent drilling.
- FLTDEM survey identifies two major EM conductors at Tillex
- Main Conductor extends strike length to 600m and depth beyond 400m
- East Conductor adds new high-conductivity target east of deposit
- Maiden drilling program scheduled to start April 2026
- Downhole EM surveys planned to refine deep conductor targets
Electromagnetic Survey Unveils New Potential
Aruma Resources Limited (ASX:AAJ) has announced promising results from a Fixed Loop Time Domain Electromagnetic (FLTDEM) survey conducted at its Tillex Copper-Silver Project, located in the prolific Timmins mining district of Ontario, Canada. The survey has successfully delineated two significant electromagnetic conductors, substantially extending the known mineralised footprint both along strike and at depth.
The Main Conductor, which aligns with the previously drill-defined high-grade Tillex deposit, now extends approximately 600 metres along strike, an increase of about 180 metres beyond earlier drilling. More notably, the conductor’s depth has been modelled to exceed 400 metres below surface, reaching 250 metres deeper than the deepest copper intersection recorded to date. This suggests the potential for substantial additional mineralisation below the current resource envelope.
New East Conductor Adds to Exploration Upside
In addition to the Main Conductor, the survey identified a second strong electromagnetic anomaly, termed the East Conductor. Situated immediately east of the Tillex deposit at an interpreted depth of around 120 metres, this conductor exhibits very high conductivity values, up to 145 Siemens, and extends roughly 200 metres along strike. Unlike the Main Conductor, this target has yet to be drill tested, representing a fresh opportunity to uncover further copper-silver mineralisation.
Strategic Drilling Program to Commence
Building on these geophysical insights, Aruma is preparing to launch its maiden drilling campaign at Tillex starting in April 2026. The program will incorporate downhole electromagnetic surveys designed to refine conductor models and target mineralisation potentially extending beyond 400 metres depth. This integrated approach aims to maximise the efficiency and precision of exploration efforts in this highly prospective district.
Managing Director Grant Ferguson expressed enthusiasm about the survey outcomes, highlighting the significance of identifying multiple coherent conductors coincident with known high-grade mineralisation. He emphasised that these results provide a compelling foundation for the upcoming drilling phase, which could materially enhance the project’s resource potential.
Context Within a World-Class Mining District
The Tillex Project sits within the Timmins mining district, a globally recognised copper and silver producing region. Aruma’s exploration strategy leverages advanced geophysical techniques and historical drilling data to unlock extensions of known mineralisation and discover new zones. The recent FLTDEM survey, conducted by specialist firms Abitibi Geoscience and St Pierre Geoconsultant Inc., employed industry-standard methodologies and software modelling to ensure robust and reliable target identification.
While the survey results are encouraging, it is important to note that confirmation of mineralisation will depend on the forthcoming drilling results. The company’s cautious optimism is balanced by the inherent uncertainties of exploration, but the expanded targets and planned drilling program mark a significant step forward in advancing the Tillex Project.
Bottom Line?
With drilling imminent, Aruma’s expanded targets at Tillex could redefine the project’s copper-silver potential.
Questions in the middle?
- Will the maiden drilling confirm mineralisation at depths beyond 400 metres?
- How will the East Conductor’s untested target influence resource estimates if confirmed?
- What are the implications of these findings for Aruma’s broader exploration strategy in Timmins?
