| Abstract | Recent geoscientific interpretation of the Baslay- Danin prospect reveals the need for exploration drilling as the next phase of evaluation. Extensive near surface boiling occurs some 7 kms from the inferred reservoir source, with spring chemistry generally reflecting a mixture of steam condensate, shallow groundwater and in some cases small amounts of deep chleride water. Mixing models suggest four to five times dilution must occur to produce surface discharge composition in Baslay-Danin, using reservoir fluid chemistry from Palinpinon. A vertical electrical sounding survey has proved an area of low-moderate resistivity (5- 50 ohm-m) greater than 20 sq. km. This confirms a connecttion at depth beneath the original low apparent resistivity anomalies of Lipayo and Nagpantaw. |
