Jun 25, 2012 (A Wilson) - The Band-Ore Horizon lies approximately 150 m south of the Kapika Zone and lies between Band-Ore gridlines L16+45E to L60+00E. Gold mineralization is hosted by Archean-aged clastic metasediments, consisting of near vertical siltstones, thickly bedded argillites, arenite and conglomerates with minor quartz-feldspar porphyries. The zone is a highly altered silicified, sericitized and carbonatized zone with pyrite and arsenopyrite mineralization. there appears to be a broad envelope of sericite ankerite alteration surrounding the gold zones with minor fuchsite, montmorillonite and quartz-ankerite veining.

Jun 25, 2012 (A Wilson) - Gold mineralization is spatially associated with cross-cutting, quartz-ankerite veins marking a reactivated fault structure. The zone can be described as a broad, weakly auriferous zone up to several tens of metres wide within variably weakly to moderately sericitized and carbonatized and arsenopyrite-pyrite-quartz-ankerite veined sediments. The sediments are weakly anomalous in gold ranging from 0.03 to 0.10 g/t Au and enriched in arsenic. Alteration and mineralization appears to be confined by impermeable chloritized and graphitic argillite beds.

Jun 25, 2012 (A Wilson) - The nature of the arsenopyrite is much different than in the other zones, as coarse arsenopyrite crystals are the dominant species as opposed to the normal acicular variety. No visible stibnite is observed and the occurrence of blebby pyrite rarely exceeds 2%.
