Vital Core Reservoir
Found in: C5C6 C Single-source / unverified Class band stated by the EVE University wiki only - no second source carries per-class spawn data for this site type. Also spawns in shattered systems of any class.
Wormhole fullerite gas site. Undefended when you land: Sleeper defenders arrive on a timer, so the pattern is huff until the rats show, then fight or reship. Fullerenes feed Tech 3 and capital production, which is why the deeper reservoirs are worth the risk. Classes it spawns in are listed above.

Two separate payouts. The gas in the site is the reason to come: ~1,382M ISK at the sheet's live prices. Killing the Sleeper defenders drops a further ~74.8M ISK in blue loot. Recheck prices before planning income, they move; the manifest quantities are the stable part.
