Aclara Announces Results from Technical Reports on Its Integrated Heavy Rare Earths Supply Chain
Aclara Feasibility Study Validates Heavy Rare Earth Strategy With 26% IRR

Executive Summary
- On April 13, 2026, Aclara Resources released NI 43-101 feasibility study results for its flagship Carina Project in Brazil and scoping/FEL-2 studies for its U.S. downstream projects (Project Dynamo and Metals & Alloys).
- The Carina Feasibility Study shows an after-tax NPV of US$1.7 billion (8% discount), IRR of 26.9%, and a payback period of 2.9 years, with construction capex estimated at US$780.9 million.
- Combined integrated chain studies project total capex of approximately US$1.21 billion across mining, separation, and alloy production, with an average IRR of ~26% and commercial start-up targeted for H2 2028.
- Production forecasts include 4,378 tonnes/year of mixed rare earth carbonate from Carina, feeding a U.S. separation facility producing 148 tonnes/year of Dysprosium oxide and 1,131 tonnes/year of NdPr oxide.
- This follows the November 2025 Pre-Feasibility Study (PFS) which showed an NPV of US$1.1 billion and IRR of 22%, indicating a significant upgrade in project economics upon conversion to Feasibility level.
- Financing progress includes the closing of Tranche 1 of a US$50 million private placement on April 2, 2026, at C$2.83 per share, with Tranche 2 expected May 12, 2026.
Material Impact
- The news confirms the bankable feasibility study that was anticipated following the PFS in November 2025, validating the technical and economic viability of the project.
- Economics improved materially from PFS to FS: NPV increased by ~54% (US$1.1bn to US$1.7bn) and IRR rose from 22% to 26.9%, reducing execution risk.
- The integrated supply chain studies (Mine-to-Alloys) de-risk the downstream revenue model, showing a clear path to value capture beyond raw carbonate sales.
- However, the capital requirement remains substantial (~US$1.21 billion total) compared to the US$50 million raised in April 2026, indicating significant future dilution or debt financing will be required before construction begins in 2027/2028.
- The news is not a "Game Changer" relative to market expectations because the PFS and financing were already priced into the stock leading up to this date; it is a confirmation of value rather than an unexpected surprise.
