KALO GOLD CORP. has identified Vuinubu Ridge to Namalau as a >1,900 meter ("m") northeast trending priority epithermal gold target located along the deep seated Nubu Graben Fault. A combination of geology, structure, geochemistry and geophysics indicates that the upper 100 to 150m of the epithermal system has been eroded and it is interpreted that subsequent trenching and shallow drilling has intersected only the upper portion of the precious metal horizon.

Shallow drill testing of Vuinubu Ridge has tested approximately 500m strike length of the trend and trenching has tested over 1,900m to the northeast to Namalau. Given that Vuinubu Ridge represents the top of the precious metal horizon it is estimated that drilling within 300m of the surface, targeting the main gold mineralized zones which are interpreted to underly the current trench and drill tested zone, are the priority for the next phase of exploration work. Fifteen holes have been drilled in Vuinubu Ridge to a maximum vertical depth of 115m.

Mineralization is open at depth and along strike for over 1900m and the interpreted zonation of this epithermal system indicates higher-grade gold potential within 300m of the surface. Compilation work has shown that Vuinubu Ridge sits on the southern bounding extensional fault of the Nubu Graben. The Nubu Graben, an extremely important deep seated regional scale NE-SW striking structure was formed by the downward drag of the Pacific Plate stretching crust resulting in rifting.

The Nubu Graben lies along the Viti Levu Lineament, sometimes referred to as Fiji's Mineralized Gold Belt which hosts large gold deposits such at Vatukoula /Emperor and Tuvatu. These types of faults extend at depth into the crust and act as conduits for the mineralizing fluids and gases to rise to the surface, which then deposit their mineral content as the system cools and condenses. Evidence is emerging through the current reinterpretation work and compilation of historical data that the Nubu Graben Fault may host additional untested epithermal centres, highlighted by their geochemical fingerprint at surface or the occurrence of rocks such as silica sinters which are associated with the hot spring environments that sit at the subaerial interface of epithermal /hydrothermal systems.
