Development layouts for the financier's secluded tropical island included in the photographs.
Also contained in this new photograph drop seems to be a site plan for the Great St James island, situated in the US Virgin Islands.
Jeffrey Epstein acquired a more modest island - Little St James - originally in 1998, but later purchased the larger adjacent island in the year 2016 for a sum of $22.5 million.
These photos suggest he had drawn up ambitious plans to develop the 161-acre island by erecting residences, an open-air theater, an submerged workspace and a reservoir.
Marked on the plan is Pillsbury Sound, a strait in the territory, marked on the lower right-hand corner.
This development map is marked up in red pen markings and includes a legend identifying various sections of the property.
Alongside this are what appear to be several other site drawings and architectural plans, featuring plans for marina coverings.
More images released as part of the ongoing investigative process.
