Centaurus Metals is developing the Jaguar nickel project in Brazil's Carajás region, targeting first production in 2030. At A$0.63 versus fair value A$0.73, the stock trades 14% below our assessment. The core question is whether low-carbon nickel can command a premium—the company's 7.27 tonnes of CO₂ per tonne of nickel is 85% cleaner than the industry average, but no pricing differential has emerged in spot markets despite two years of EU carbon border regulations.

The best fit is thematic investors with high risk tolerance. Centaurus offers pure exposure to the low-carbon nickel thesis—7.27 tonnes CO₂ per tonne of metal positions it to capture any CBAM or IRA premium that emerges. The three-to-five-year horizon aligns with regulatory validation: CBAM Phase 2 enforcement begins in 2026, and battery supply chain decarbonisation mandates tighten through 2028. This suits patient capital willing to accept binary outcomes as the decarbonisation premium either validates or fails.

Centaurus Metals is developing a nickel mine in Brazil's Carajás province with 1.2 million tonnes of nickel resources (71% Measured and Indicated confidence). The company secured all environmental permits by October 2025—12 to 24 months ahead of North American peers—and aims for a Final Investment Decision in 2027. Revenue begins in 2030 after three years of construction. The business model hinges on producing low-carbon nickel concentrate (7.27 tonnes CO₂ per tonne, 85% cleaner than the industry average) and selling it at a premium to battery and stainless steel manufacturers seeking certified supply chains.

Recent performance has been administrative rather than operational: the company raised A$23.1 million in September 2025 and completed its feasibility study in July 2024, demonstrating a project net present value of US$663 million at a 31% internal rate of return. Strategic partner negotiations have extended beyond two years without a binding agreement, signalling either challenging market conditions or management's term expectations.

The investment case rests on three pillars: exceptional permitting execution (construction-ready status), robust project economics (first-quartile cost positioning at US$3.34 per pound), and potential low-carbon pricing premiums (3% to 10% above commodity nickel). The risk centres on financing—30% to 40% equity dilution is required, and the strategic partner remains unidentified. At A$0.63 versus fair value A$0.73, the stock is 14% undervalued.

What happened?

As a pre-revenue developer, Centaurus burns approximately A$2.4 million per quarter on corporate overhead, permitting, and engineering studies. The second quarter of fiscal year 2026 brought two milestones: the Mining Lease was granted in October 2025 (the final approval required for construction), and basic engineering design reached completion. Net cash stood at US$25 million, providing roughly ten quarters of runway to the Final Investment Decision. Value Engineering studies are targeting concentrate grade improvements—from 28%–32% nickel content (peer average) to 34%—which would reduce freight costs and improve smelter payability.

What's next?

The critical path is securing a strategic partner by mid-2027 (Base case scenario). This triggers the Final Investment Decision, unlocking US$371 million in construction capital. Construction runs from 2027 through 2030, with first nickel concentrate shipments in the second half of 2030 during commissioning. The production ramp extends through 2031 to 2032, reaching nameplate capacity of 25,300 tonnes of nickel annually by 2032.

Three near-term catalysts matter: CBAM Phase 2 certificate trading in the first half of 2026 (premiums above 5% would validate the low-carbon thesis), strategic partner announcement in the second or third quarter of 2027 (binding terms clarify dilution and offtake pricing), and Chinese nickel inventory trends (decline below 120,000 tonnes signals destocking has completed and cyclical recovery may begin). Bear case risks include strategic partner failure, triggering either asset sale at US$200 million to US$250 million or distressed equity raising at 50% to 60% discounts to net asset value.

What could go wrong?

The low-carbon premium may not materialise. Centaurus assumes nickel sells at a 4% premium (Base case) due to its 7.27 tonnes CO₂ per tonne emissions profile. Yet EU Carbon Border Adjustment Mechanism certificates have traded below 3% since Phase 1 launched, and no battery manufacturer or stainless steel producer has signed an offtake contract specifying carbon-based pricing.

If the premium compresses to 2% (Bear case), net revenue per tonne falls from US$14,620 to US$13,000—an 11% reduction. This flows through 51% EBITDA margins, compressing fair value by A$0.18 per share, or 18%. The trigger is CBAM Phase 2 enforcement in 2026 to 2027: weak certificate trading or delayed EU penalties would confirm commoditisation. Chinese battery makers prioritising cost over carbon, or Indonesian high-carbon supply capturing Western market share despite regulation, would invalidate the differentiation thesis entirely.

The secondary risk is strategic partner failure. After two years without a binding agreement, the 15% probability Severe case models asset sale at US$200 million to US$250 million (31% below Base case fair value) or distressed equity raising diluting shareholders by 80%. Current net cash of US$25 million covers only ten quarters—if negotiations extend into 2028, liquidity pressure forces unfavourable terms or abandonment.
