Harena
Harena Highlights
- Third VMS near surface discovery on Bisha licenses
- Oxide gold cap near surface
- Copper and zinc primary sulphide underneath
- Potential additional feed for Bisha both in CIL and flotation phases
Harena Overview
The Harena VMS (volcanogenic massive sulphide) deposit lies within the Bisha exploration license. Harena lies 10 km southwest, easy trucking distance, from the Bisha Main deposit. Nevsun views the Harena deposit as a very likely source of supplemental feed for the processing plant at Bisha for both the gold and base metal phases. The feed would provide additional cash flow as an extension to mine life without significant capital expenses.
Harena was originally selected as a potential exploration target based on an alteration anomaly defined on Landsat imagery. A subsequent airborne EM survey defined a moderate conductor on what was interpreted to be the same stratigraphic horizon as the Bisha Main deposit. Diamond drilling in 2005 intersected various widths of oxide and sulphide mineralization over a strike length of 400 meters confirming the presence of a satellite VMS deposit.
