Island of St. Vincent, St. Vincent and the Grenadines

Geothermal Exploration and Environmental Baseline Geothermal Resource Assessment

Client : Growth Capital Holdings , (North American Geo Power)
Geologica Geothermal Group personnel worked on the initial exploration of geothermal resources on St. Vincent Island. Our work involved two phases of geochemical sampling of cold and warm springs, fumaroles and streams, field and laboratory analysis and data interpretation after preliminary reconnaissance identified an initial exploration target area around the island’s youngest volcanic features. Analytical results were interpreted to evaluate the nature and extent of a hydrothermal system and establish the baseline water quality of the hydrological system. Typical of many underdeveloped country’s site conditions on St. Vincent required that fieldwork was conducted primarily on foot due to limited vehicular access and poor map coverage. Field logistics required importing equipment into the country and exporting all of the samples collected. The initial phase of the project focused on evaluating the geothermal development potential by identifying, sampling and analyzing surface manifestations. A second phase of sampling and analysis was conducted based on the analytical results from the first phase. The geochemistry suggested high temperature reservoir conditions, deep circulation and some contribution of volcanic derived waters in some of the surface manifestations. The geochemical data were used to outline the approximate extent of the system, locations of recharge and discharge and potential resource temperatures and contributed hydrological data to the environmental baseline studies for the project. Results and findings were presented in a report.
