The sulphide enrichment gold deposit model best describes the mineralization of the Bradshaw Deposit.

The sulphide enrichment deposit model is characterized by a dominance of sulphide minerals over quartz veins, and is localized in shear zones adjacent to rheologically differing mafic to ultramafic volcanic rocks of tholeiitic petrochemistry. Mineralization typically comprises native gold associated with disseminated to massive arsenopyrite and vein hosted pyrite and arsenopyrite in silicified chloritic and sericitic schists, within a broad zone of potassium metasomatism and wall rock sulphidation (disseminated pyrrhotite and pyrite). Carbonatization of the wall rocks is a less conspicuous feature than silicification. Pervasive silicification and silicate alteration minerals developed within the shear zone consists of quartz, albite, chlorite, actinolite, tourmaline and amorphous carbon, suggesting a dominance of silicic and potassic alteration.

The Bradshaw Deposit comprises a geological Main Zone and several lesser Hanging Wall Zones. Gold mineralization in the Main Zone occurs primarily within a fractured and brecciated altered horizon previously interpreted as a shear zone in hanging wall basaltic flow rocks at or near the contact with steeply north-dipping (85°) footwall ultramafic rocks to the south.

Within the geological Main Zone, higher-grade gold mineralization is localized along the footwall of the horizon, termed the MZ1 Zone (pre ........

The Bradshaw Deposit is comprised of 8 steeply dipping (60-85 degrees) zones with a nominal thickness of 2-3 metres/zone and an overall strike length of 1,000 metres. The various ore zones are intermittent and discontinuous across the deposit, however, have continuity as sub economic mineralized sulphide horizons that can be followed along strike and down dip.

The longitudinal longhole (blasthole) stoping with unconsolidated and cemented crushed rockfill (waste rejects from the sorter) has been selected as the primary mining method. This will allow the level development to occur within the mineral wireframes, and any development connecting the various ore zones (which is below the cut-off grade) will be stockpiled as mixed development material at the entrance of the portal. This material will be later be put through the ore sorter in order to concentrate any potential gold material before sending to the mill.

Sublevels have been designed at 30 metre vertical intervals (floor to floor) compared to 20 metres in order to reduce development costs. On each sublevel, the deposit will be accessed from the centre and developed east and west along strike to a minimum size of 4 metres by 4 metres (allow travel of 6 yds LHDs). In most cases, an overcut and undercut will be developed to mine the deposit, but in some instances, only an undercut will be developed, followed by longhole uppers including inverse raising. Longitudinal mining will retreat from the outer l ........
