Estrella Resources

What Estrella Resources does

Estrella Resources Limited (ASX: ESR) is an Australian minerals exploration and development company headquartered in Perth, Western Australia, focused on discovering and developing nickel and manganese assets. The company operates three distinct exploration projects: the Timor-Leste Project (approximately 504 km2 of Exploration and Evaluation Concessions and Reconnaissance Permits targeting manganese in the Noni Formation in Lautém Municipality); the Carr Boyd Nickel Project (228 km2 of tenure in Western Australia's Eastern Goldfields, 80 km from Kalgoorlie, covering the Carr Boyd Igneous Complex with massive sulphide discoveries at T5 and Broonhill); and the Spargoville Project (high-grade nickel located 20 km south-west of Kambalda, with a JORC 2012-compliant Maiden Mineral Resource of 127,000 tonnes at 1.9% Ni and 0.15% Cu at the 5A deposit). Its exploration technology stack includes drilling campaigns, world-first Time-Domain Audio Frequency Magnetotellurics (AFMAG) surveys deployed in late 2023, next-generation TargetEM electromagnetic systems from Expert Geophysics, and a generational geological model developed in partnership with CSIRO explaining Ni-Cu sulphide mineralisation at T5, Broonhill, Carr Boyd and Mossgiel.

The company is pre-revenue and currently monetises nothing commercially; its stated business model is to advance projects through exploration and feasibility, then generate revenue through direct offtake agreements with major mining companies and commodity traders for nickel and manganese production. Go-to-market is investor-focused via ASX announcements, an investor hub, presentations and webinars. Its go-to-customer motion will be future offtake sales — Glencore's Murrin Murrin facility has already processed a 2,500-tonne trial parcel from the 5A deposit in 2023, establishing a precedent for downstream commercial pathways. Key customer/government counterparties include the Timor-Leste National Petroleum and Minerals Authority (ANPM) and state-run Murak Rai Timor (MRT), with whom a binding MoU establishes a joint venture under which MRT is free-carried at 30% until a Definitive Feasibility Study is approved. The company is governed by a five-member board (Non-Executive Chairman, Managing Director, Non-Executive Director and Company Secretary) with prior involvement at BHP, Rio Tinto, Petra Diamonds and Majestic Resources, and operates a permanent managing branch (ESR-RP) in Dili, Timor-Leste.

Core offering

Estrella Resources Limited is a minerals exploration and development company that identifies, explores and advances nickel projects in Western Australia (Carr Boyd and Spargoville) and manganese assets in Timor-Leste. The company combines active prospecting, advanced geophysical survey technologies and drilling programs to progress exploration concessions toward mineral resource definition and eventual production for sale to offtake partners.

Product overview

Estrella Resources is a minerals exploration and development company operating three distinct exploration projects: the Timor-Leste Project (manganese assets in virtually unexplored territory covering 504+ km2), the Carr Boyd Nickel Project (nickel-copper sulphides spanning 228 km2 in the Eastern Goldfields of Western Australia), and the Spargoville Project (high-grade nickel with a JORC-compliant maiden resource at the 5A deposit). The company combines active prospecting, advanced technologies, and drilling to advance these projects toward development.

Products and services

• Timor-Leste Manganese Project Manganese exploration project in Timor-Leste covering approximately 504 km2 of Exploration and Evaluation Concessions and Reconnaissance Permits in the Lautém Municipality, focused on the Noni Formation geological structure defined over 47km strike length. Targets high-grade manganese occurrences in virtually unexplored territory under a binding MoU with state-run Murak Rai Timor.
• Carr Boyd Nickel Project Nickel-copper exploration project spanning 228 km2 in Western Australia, 80km from Kalgoorlie, featuring massive sulphide discoveries at T5, Broonhill and other prospects within the Carr Boyd Igneous Complex. Uses AFMAG and TargetEM survey technologies in partnership with CSIRO to identify Ni-Cu sulphide mineralisation targets.
• Spargoville Nickel Project High-grade nickel project located 20km south-west of Kambalda, Western Australia, covering historic operations including the 1A, 5A, 5B and Andrews (5D) deposits. Features a JORC 2012-compliant maiden Mineral Resource of 127,000 tonnes at 1.9% Ni and 0.15% Cu (2,370t contained nickel) at the 5A deposit, with high-grade intercepts including 15m at 10.45% Ni. Trial processing of a 2,500 tonne parcel was conducted at Glencore's Murrin Murrin facility in 2023.

Quantifiable outcome

• 5A maiden Mineral Resource: 127,000 tonnes at 1.9% Ni, 0.15% Cu (2,370t contained nickel)

• Murak Rai Timor (MRT)flagshipStrategic or Co-development Partner · 1 January 2023Binding Memorandum of Understanding (MoU) with state-run Murak Rai Timor (MRT) to create a joint-venture partnership controlling Estrella Resources' activities within Timor-Leste. MRT will be free-carried at 30% ownership up until publication and approval of a Definitive Feasibility Study on any mineral discovery, after which MRT can contribute costs or transfer interest for a production royalty.
• CSIRO (Commonwealth Scientific and Industrial Research Organisation)coreStrategic or Co-development PartnerPartnership with CSIRO to develop a new, updated and scientifically-based generational model for the Carr Boyd project. The study concluded that Ni-Cu sulphides at T5, Broonhill, Carr Boyd and Mossgiel have been generated separately from one another, unlocking rationale for exploration targeting.
• GlencoreminorChannel Partner/ Reseller/ DistributorIn 2023, the company successfully mined and processed a 2,500 tonne trial parcel of transitional material at Glencore's Murrin Murrin facility near Laverton in WA, paving the way for project development studies at the 5A deposit.

Direct peers

• Panoramic Resources: ASX-listed nickel-copper producer/explorer with the Savannah mine in WA, historically a Kambalda-region operator. Direct peer for WA nickel sulphide mining with similar geography and target minerals.
• Karora Resources: TSX-listed gold-nickel producer with significant WA nickel sulphide exposure (Beta Hunt). Comparable in critical-mineral focus and operating geography, though at a more advanced production stage.
• Poseidon Nickel: Long-standing ASX-listed nickel developer/producer at the Black Swan project in WA's Goldfields, near Kalgoorlie. A direct regional peer for Estrella's Carr Boyd and Spargoville assets, though at a more advanced stage.
• Ardea Resources: ASX-listed developer of the Kalgoorlie Nickel Project (KNP), one of the largest undeveloped nickel sulphide resources globally. Direct peer in WA nickel-cobalt exploration and downstream critical-minerals strategy.
• Jervois Global: ASX-listed nickel-cobalt developer with projects in Australia, Brazil and the US. Comparable in critical-minerals focus and the trial-processing/offtake pathway Estrella is pursuing at Murrin Murrin.
• Widgie Nickel: Small ASX-listed nickel explorer focused on tenements near Kambalda and Mt Edwards in Western Australia. Highly comparable in scale, stage and geography to Estrella's Carr Boyd and Spargoville assets.
• St George Mining: ASX-listed explorer with nickel-copper-PGE projects in the Eastern Goldfields of WA. Closely aligned to Estrella's nickel sulphide focus, junior scale, and ASX-listed exploration profile.

Broad incumbents

• BHP Group: Operates the BHP Nickel West division across the Kambalda/WA Goldfields, including processing infrastructure used by many juniors. Broad incumbent whose footprint and infrastructure are direct comparables to Estrella's WA assets.
• IGO Limited: ASX-listed nickel and lithium major with extensive WA exposure, including the Nova operation and the Cosmos/Liontown portfolio. Broader portfolio incumbent in the same critical-minerals space as Estrella.

Emerging players

• Strandline Resources: ASX-listed critical-minerals developer of mineral sands (zircon, titanium) with no direct nickel/manganese overlap but a similar small-cap, Australia-listed critical-minerals profile that competes for the same investor pool.
