Rock Hoffman Blasko's questions to Sigma Lithium Corp (SGML) leadership • Q1 2025
Question
Rock Hoffman Blasko of Bank of America inquired about the rationale for producing 5.0% spodumene concentrate and asked for details on future cost optimization potential.
Answer
Co-Chairperson and CEO Ana Cabral Gardner explained the move to 5.0% concentrate was a conscious decision. By adding reprocessed material from the recycling circuit, Sigma exponentially gains mass, which significantly lowers costs. She noted the market currently does not offer a sufficient premium for higher-grade material. Regarding future cost reductions, she clarified that the primary driver for lowering all-in sustaining costs to the target of $530/tonne will be economies of scale from halving SG&A and interest expenses with the second plant, rather than further cuts to already low operational costs.
