Aruma Resources has reported standout wide, high-grade copper and silver drill results from its Phase 1 program at the Tillex Project in Ontario, reinforcing its potential as a major copper development asset.
- Phase 1 drilling reveals multiple wide, high-grade copper-silver zones
- Discovery of copper mineralised feldspar porphyry expands exploration targets
- Deepest hole confirms down-plunge continuity and zinc as vector for VMS system
- Phase 2 drilling of 3,500–4,000m planned to test strike extensions
- Metallurgical testwork to assess processing characteristics scheduled for Q3 2026
Phase 1 Drilling Confirms Large-Scale, High-Grade Copper-Silver System
Aruma Resources (ASX:AAJ) has unveiled a series of impressive drill intersections from its initial diamond drilling at the Tillex Copper-Silver Project in the Timmins mining district, Ontario. Highlights include an 89m intercept grading 2.04% copper and 12.31g/t silver from just 38.8m depth, alongside other substantial intervals exceeding 1.9% copper with strong silver credits. These results underscore a continuous, shallow, high-grade mineralised system that remains open along strike and at depth, positioning Tillex as a compelling copper development opportunity.
Such wide zones of mineralisation at relatively shallow depths are rare and suggest the potential for a significant resource base. The consistency and scale of these intersections reinforce earlier drilling campaigns and provide a robust foundation for advancing the project.
New Copper Mineralised Feldspar Porphyry Emerges as Exploration Target
Beyond the primary argillite-hosted mineralisation, Aruma has identified copper mineralisation within a feldspar porphyry horizon; a feature previously underappreciated at Tillex. Multiple intersections surpassing 0.2% copper over significant widths hint at an additional mineralised system. The company plans to include representative porphyry samples in upcoming metallurgical testing to understand processing characteristics and will tailor future drilling to evaluate its potential both as a vector to the main mineralised zones and as an independent copper host.
Deep Drilling and Zinc Anomalism Support VMS Mineralisation Model
The deepest hole in Phase 1, TX26-001, confirmed that the targeted conductor extends at depth, intersecting anomalous zinc mineralisation typical of the hydrothermal halo around volcanogenic massive sulphide (VMS) deposits. Zinc's presence acts as a directional vector towards higher-grade copper zones, bolstering the interpretation of a plunging copper-rich core yet to be fully tested. This geochemical zonation, combined with structural controls and downhole electromagnetic surveys, sharpens the focus for Phase 2 drilling.
These findings align with the company's view that Tillex shares important structural and geometric similarities with the nearby world-class Kidd Creek VMS deposit, which is renowned for its exceptional vertical continuity and large-scale copper-zinc-silver mineralisation.
Phase 2 Drilling and Metallurgical Testwork on the Horizon
Building on these promising results, Aruma plans to commence a 3,500 to 4,000m Phase 2 diamond drilling program targeting strike extensions and depth extensions of the mineralised system. Concurrently, metallurgical testwork will begin in early Q3 2026, assessing both the argillite-hosted and feldspar porphyry mineralisation. The testing aims to determine optimal processing pathways, metal recovery rates, and concentrate quality; critical inputs for any future economic studies.
Importantly, the Phase 1 drilling has confirmed low levels of deleterious elements such as arsenic and cadmium, which could simplify processing and environmental management. The presence of chalcopyrite, a favourable copper sulphide mineral, further supports conventional flotation processing methods.
Strategic Implications for a Copper-Focused Explorer
Aruma’s progress at Tillex marks a significant step in validating the project’s potential within a globally recognised mining district. The combination of wide, high-grade copper-silver intervals, emerging new targets in feldspar porphyry, and supportive geochemical and geophysical vectors suggests a robust, expanding mineral system. The upcoming drilling and metallurgical programs will be pivotal in refining resource estimates and advancing development options.
With the Timmins district's pedigree and the nearby Kidd Creek deposit setting a high benchmark, Aruma’s findings at Tillex warrant close attention as they unfold.
Bottom Line?
Aruma Resources' strong Phase 1 results at Tillex set the stage for a critical Phase 2 drill campaign and metallurgical studies that will test the project's scale and economic viability.
Questions in the middle?
- Will Phase 2 drilling confirm the interpreted plunging high-grade copper zone?
- How will the feldspar porphyry mineralisation influence resource growth and processing?
- What metallurgical recovery rates and concentrate qualities will the upcoming testwork reveal?
