Site blueprints for the financier's secluded tropical island among the released materials.
Additionally featured in this recent photograph drop is shown to be a site plan for Great St James island, located in the Caribbean US territory.
The financier acquired a smaller island - Little St James - originally in 1998, but subsequently obtained the larger adjacent island in 2016 for a sum of $22.5 million.
The released images suggest he had drawn up plans to develop the substantial island by constructing living quarters, an amphitheatre, an office beneath the waves and a swimming pool.
Marked on the plan is a local waterway, a strait in the territory, noted on the lower right-hand corner.
This development map is marked up in handwritten red notes and contains a key identifying distinct parts of the land.
Accompanying the main plan are what appear to be several other property layouts and construction drawings, such as plans for dock shelters.
More images made public as part of the continuing investigative process.
