Abstract
The Waesano Geothermal Project is located on Flores Island, Indonesia. Surface exploration has been completed, including geological mapping, geochemical sampling, and geophysical surveys including MT and gravity. A conceptual model of the reservoir has been constructed that features a high-temperature ( more than 240°C) volcanic-hosted geothermal reservoir, at least partly neutral saline, but with an acid-magmatic centre. The resource is developed in Paleogene to Neogene sedimentary and volcanic rocks at a depth of more than 1000-1300 mVD and is estimated to be capable of generating at least 30 MW. The next step of the project is an exploration drilling campaign.
