Aclara Announces Filing and Results of Feasibility Study for Its Flagship Carina Project
Aclara Resources Feasibility Study Delivers Stronger Economics Than PFS, But Capital Gap Looms Large

Executive Summary
- On April 13, 2026, Aclara Resources filed a NI 43-101 Feasibility Study (FS) for its flagship Carina Project in Brazil.
- The study reports an after-tax NPV of US$1.7 billion (8% discount), up from the US$1.1 billion reported in the November 2025 Pre-Feasibility Study (PFS).
- After-tax IRR improved to 26.9% from 22% in the PFS, with a payback period shortened to 2.9 years from 4.5 years.
- Total Construction CAPEX is estimated at US$780.9 million (US$678.2 million construction + US$102.7 million contingency), which is approximately US$100 million higher than the PFS estimate of US$680.5 million.
- Production profile remains robust with 4,378 tonnes per year of Rare Earth Oxides (REO), including 156 tonnes of Dysprosium and 27 tonnes of Terbium annually.
- Timeline targets first production in H2 2028, with early site works beginning Q3 2026.
- The study confirms Aclara is the only company reporting heavy rare earth reserves from ionic clays under NI 43-101 standards.
Material Impact
- Economic Improvement: The Feasibility Study results represent a material improvement over the PFS, with NPV increasing by approximately 54% and IRR rising nearly 5 percentage points. This significantly de-risks the project economics for potential lenders and off-takers.
- Capital Intensity Reality Check: While economics improved, CAPEX increased by ~15% (US$680M to US$780M). The company has raised only US$50 million via private placement as of April 2026 against a US$780 million construction requirement. This creates a substantial funding gap that must be addressed before construction can commence in late 2026/early 2027.
- Market Expectation: The FS was anticipated following the PFS announcement in November 2025 and the CEO's December 2025 outlook. However, the magnitude of the economic upside (NPV jump) exceeds standard expectations for a development-stage miner transitioning from PFS to FS.
- Strategic Validation: Confirmation of heavy rare earth reserves under NI 43-101 validates the company's unique positioning in the ionic clay sector, supporting long-term valuation premiums relative to peers.
