Within the altered breccia complex mineralization consists of minor disseminated pyrite, native sulphur, and locally traces of cinnabar, realgar and orpiment. The program met its objectives, successfully filling in the gaps in the resource model, extending and defining the near surface limits of previously known mineralization (as shown on the attached map) and resulting in the discovery of a new zone of mineralization, the Realgar Zone, at the intersection of the Black and Central Zones. Within the intrusive and intrusive breccia, oxidation is less well developed and primary sulphides and realgar are observed in a number of drill holes. |
