Ann: Polelle AC drilling results, page-5

GBR entered a 12 month option agreement to acquire 75% of Polelle on 30 November 2023, presumably it expires on 29 November 2024.
The option can be exercised by spending $250,000 and paying a further $100,000 in scrip to Castle within the 12 month period. On exercise Castle will need to contribute 25% of ongoing exploration, so the sooner we exercise the sooner we share.

If GBR don't spend the $250,000 by 29 November 2024 they can extend the option by paying a second fee of $100,000 and spending $400,000 on exploration. Obviously, this is a much more expensive option which may explain why Andrew is keen to spend the money within the first 12 month period just in case there are delays with heritage clearances.
