In June 2024, Galileo completed a farm-in and joint venture agreement with a wholly owned subsidiary of Mineral Resources (ASX:MIN) (MinRes) for the sale of a 30% interest in all lithium rights held by Galileo on the Norseman tenement package for A$7.5 million cash consideration.

MinRes and Galileo have formed a 30% / 70% unincorporated joint venture for the exploration and, if deemed warranted mining of, lithium on the Norseman tenements. The Callisto PGE-nickel deposit, on M63/671, is not a part of the exploration JV agreement.

In November 2025 the JVA parties agreed the following changes to the Lithium Exploration JVA : 

· A suspension to the Earn-In Period for a maximum of two (2) years from 30 November 2025 (Earn-In Suspension Period).

· During the Earn-In Suspension Period MinRes is entitled to conduct, at its own expense, various low impact non ground disturbing exploration activities over the Lithium Exploration JVA tenements including mapping, rock chip sampling, geochemical surveys, geophysics, heritage and environmental surveys.

· During the Earn-In Suspension Period MinRes can elect to Restart the Earn-In Period by paying Galileo a further $1.5m (Restart Payment).

· Upon the Restart Payment being paid to Galileo, the Earn-In Period and full exploration activities will resume, with MinRes required to expend $12.5m (previously $15m) to meet the Earn-In Requirement to increase its stake in the Lithium Exploration JVA to 55%.
