Mineralization and alteration
The Jengibre project was originally sampled by GoldQuest geologists during the regional stream sediment programme funded by Gold Fields. Follow-up of a highly anomalous stream sediment sample discovered outcropping mineralization exposed in a creek. Of fourteen rock samples taken during the original recon phase, seven returned values greater than 5.40 % Zn (the highest four zinc values ranges from 23.10 to 30.00% the maximum analytical limit of the package used). Other maximum values from the samples included 5.12 g/t Au, 480 g/t Ag, 5.2% Cu and 260 ppm Mo.

Follow-up work by Gold Fields has defined several new areas of hydrothermal alteration and mineralization in the vicinity of the original discovery. Recent rock sampling has returned sample values up to 17.7 g/t and 14.1 g/t Au associated with zones of intense silica-pyrite alteration. Outcropping mineralization has now been identified in five principal zones, four of which are located over a horizontal distance of approximately 1,000 meters. The mineralized outcrops occur at a similar topographic level, suggesting possible lateral continuity of the zones in the form of a shallow dipping stratiform body cross-cut by several sub-vertical faults and possible feeder structures. The fifth zone is located approximately 500 meters further east, where preliminary rock samples grade up to 4.7 g/t Au from a zone of silica-pyrite alteration which trends approximately 450 meters east-west. The style of alteration and mineralization of the fifth zone is similar to that occurring in the other zones.
