Ann: Bluebird Expansion Update, page-17

I suspect your last sentence sums it up.

Bluebirds mill that used to bear a 1.6 to 1.8MT rating in WGX preso's is now just 1.8MT

Previous owners rated it originally at 3Mt then pumped 2.7MT thru it which dropped to 2.3Mt

As previously stated When bought rated at 2.5Mt

One can naturally suspect the crushing side may be up to higher rates if ore softer and residency for yield maybe being a current issue.

Scour the last QTRLY for the mention of MORE metallurgically benign ore as an aside comment (I read this as a ore issue)

Andaman plant should it become available further south might supply bits for a cheap upgrade of either Tuka or Bluebird in the future is my thought or maybe more.

I don't think WB is into long term distance trucking if he can sit an enlarged mill next/near to a resource for less per ounce cost over time.
WB appears to be giving WGX's a NST sort of going over,putting a lot of things right.
Just like BB employing managers 6 months before a expansion spurt,I don't see unused RETAINED underground equipment sitting collecting rust for long.
