Key Highlights

  • Aruma acquired a 90% interest in patented mineral right PAT4887, located immediately along strike to the north-east of the high-grade Tillex copper-silver zone
  • The Acquisition extends the interpreted Tillex mineralised trend by approximately 760m to a total strike extent of 3.2km, open in all directions
  • Phase 2 diamond drilling has extended the continuous high-grade zone to approximately 230m to the south-west, with assay results pending for a further 130m
  • The Tillex Project sits in the Tier-1 Timmins Mining district in Ontario, Canada, one of the world's most established base metal jurisdictions

Aruma Resources Limited (ASX: AAJ), the Western Australian-based explorer with a flagship copper-silver project in Canada, has moved to secure a strategically significant land package adjacent to its Tillex discovery in Ontario's Timmins mining district, extending the interpreted mineralised corridor to a total strike length of 3.2 kilometres.

The company announced on 27 October 2026 that it had entered into a definitive agreement with private Canadian landowners to acquire a 90% interest in patented mineral right PAT4887, situated immediately along strike to the north-east of the high-grade Tillex Copper-Silver Deposit. The acquisition adds approximately 760 metres to the interpreted mineralised trend and connects directly with the area being tested by Aruma's ongoing Phase 2 diamond drilling campaign.

Tenure Gaps Closed, District-Scale Potential Opens

The acquisition of PAT4887 is described by the company as a core addition to the Tillex Project area. The new ground provides Aruma with direct continuity of tenure north-east of the existing high-grade zone — territory that lies along the interpreted north-east continuation of the prospective stratigraphy, structural corridor, and mineralised trend that hosts copper-silver mineralisation at Tillex.

Managing Director Grant Ferguson described the acquisition as a key component of the company's expansion strategy for the Tillex Project: "This acquisition of a new patented mineral claim at the Tillex Project forms a key component of our expansion strategy. With the interpreted Tillex Trend now extending to 3.2km and open in all directions, the district-scale potential of the system continues to grow."

One of the notable features of the Timmins district is the historical precedent for large, structurally controlled base metal systems. Securing tenure along the full extent of interpreted stratigraphy is a standard de-risking step for explorers operating in this environment, as gaps in tenure can complicate eventual resource definition and development planning.

Phase 2 Drilling Continues to Expand the Zone

Concurrently with the land acquisition, Aruma's Phase 2 diamond drilling program has been extending the continuous high-grade mineralised zone at the Tillex Deposit to the south-west. The zone has now been extended to approximately 230 metres in that direction, with assay results pending for drilling that has advanced a further 130 metres beyond that point. The boundaries of mineralisation remain open in all directions.

The combination of ongoing drilling expanding the known zone to the south-west, and the new tenure providing tested ground to the north-east, positions the company to begin assessing the full 3.2-kilometre trend systematically. Near-term drilling is planned at the newly acquired claim as a priority.

Sector Context

Copper Demand continues to be driven by electrification themes — electric vehicles, grid infrastructure, and renewable energy systems all require substantially more copper than legacy applications. The Timmins district in Ontario has a long history of base metal production and is generally regarded as a Tier-1 mining jurisdiction, offering stable Royalty frameworks, experienced mining services sectors, and well-developed infrastructure. For early-stage explorers, project location in recognised mining jurisdictions tends to reduce permitting uncertainty and can facilitate easier access to Capital when projects mature.

Risks and What to Watch Next

Aruma is at an early stage of resource definition at Tillex, and assay results for the extended Phase 2 drilling remain pending. The mineralised zone is open in all directions, but depth and width continuity need to be confirmed across the full strike extent before the scale of the system can be accurately assessed. The company carries a large Issued Capital base of over 1.5 billion shares, which is a dilution consideration for any future capital raises.

Investors will be watching pending assay results from the Phase 2 south-west extension, the timing and scope of drilling on the newly acquired PAT4887 ground, and any update on the total resource inventory at Tillex.
