A number of boreholes were made to investigate the existence of more sulfide lenses at deeper levels. Two (2) surface drilling rigs were mobilized to drill boreholes up to 900m in length, each. The campaign aims to minimize drilling footprint (borehole collars are in Stratoniki village), deploying many boreholes from a single drilling pad.
It has been a strong challenging project.
- Deep holes crosscutting 800m of overburden
- Irregular ore lenses on the fault footwall
- Variable rock conditions
- Crosscutting several lithologies and scares pegmatite veins
Several orebody lenses were discovered so far verifying the continuation of the -almost- mined-out orebody. More boreholes are needed, to increase geological confidence, before the lenses may define a continuous body.
