No, they bought a platform to have optionality on developing a future discovery, not specifically SM70.

Strategic lease optimisiation (expiration, re-bidding) should be commended as a prudent strategy to retain an interest whilst deferring drilling commitments. It's effectively banking an option on a non-primary asset.

As far as not being able to afford to drill...that's a bit of a throwaway comment that ignores the many mechanisms available to an ASX listed company to fund its operations. They're purchasing a future pipeline of potential opportunities that they have a choice over whether to drill (and when) or not. This comes back to an understanding of the company strategy.
