"The Great Fingall mine that had produced 1.9 Mt @ 19.8 g/t for 1.2 million ounces up to closure in 1918. The mine
has never re-started due to ownership and tenure issues, including a depth related strata-title of JV interests.
These issues have now been resolved with Metals X owning 100% of Great Fingall. Recently completed drilling has
shown that the ore systems continue down-plunge and remain open." MLX 2012

The last crush in 1918 before two weeks notice of closure was immediately posted produced 23dwt per ton from "The big blow" with tenurer miners likely to receive only 5/- a shift after final crush and various charges/expenses.Their initial payment was posted as 2.5/- a ton upfront.(Newspaper archive)
Historical comments of grade dropping below 18th level prior to closure and intermittent stops to mining between 1914-1918,for driving.
implies it was mined by TUT and TRIBUTE miners.
One contracting upfront for access driving and the other mining at their total personal cost.

My guess would be JV's financed each drive to the next mining area/depth/period
e.g.
1907 Borra Borra -Mr Horn takes an option on the Mine to run to 13 May and later he takes a one sixth interest in Great Fingall Consolidated and a five sixth interest in a 9 month option

Just a bit of history
