Guyana Super Pit Discovery, page-166

The vibe is improving . . and for those (like myself) who enjoy a good mystery romance . . involving historic quests and gold . .  and maybe with just a bit of slack for the translation involving "fresh water" . .

( . . from Wikipedia . . )

"The Essequibo River (Spanish: Río Esequibo) is the largest river in Guyana, and the largest river between the Orinoco and Amazon. Rising in the Acarai Mountains near the Brazil-Guyana border, the Essequibo flows to the north for 1,014 kilometres (630 mi) through forest and savanna into the Atlantic Ocean. With a total drainage basin of 69,300 sq.km (26,757sq.mi) with average discharge of 74,303 cu ft/s (2,104 m3/s) . . . "

Looks like Troy's tenements are in an adjacent catchment some 50kms to the west, draining east and north to the Mazaruni River to meet with the Cuyuni River then into the Essequibo as it heads to the Atlantic . . where there are numerous estuarine islands, (and the fresh and salt waters mix) . . Eldorado ?  . . rather than a fairy tale, it's a vision we're seeking to confirm . . so we're drilling !
