Development plans for the financier's secluded tropical island included in the photographs.
Also included in this latest image drop seems to be a site plan for the Great St James island, found in the Caribbean US territory.
Epstein purchased a more modest island - the Little St James - originally in 1998, but acquired the bigger adjacent island in the year 2016 for a sum of $22.5 million.
These photos indicate he had created development schemes to develop the 161-acre island by building residences, an performance venue, an underwater office and a pool.
You can see the blueprint is a local waterway, a marine passage in the US Virgin Islands, indicated on the south-eastern section.
The site plan is annotated in red pen markings and contains a notes section detailing distinct parts of the property.
Alongside this are what seem to be several other construction diagrams and architectural plans, including designs for marina coverings.
Additional documentation made public as part of the current investigative process.
