B-1 - Area 1, Coromandel Forest Park – Assessment of Environmental Effects 16 OGNZL has confirmed the Wharekirauponga resource in the area of MP60541 up to 450 m below ground level.2 It may extend deeper and this will be confirmed through further exploration drilling. WSP (2022b) describes the Wharekirauponga resource as comprising “a number of epithermal veins within host rhyolite domes. The rhyolite domes are overlain by pyroclastic units and post mineralisation andesite, though various streams at the site have eroded through the cover rocks to expose the underlying rhyolite”. The system comprises three main veins (referred to as the ‘EG Vein’, ‘T Stream Vein’ and ‘Western Vein’). Each of these consists of a main vein several metres wide, with hanging wall and footwall stringer vein sets also present. The entire area is overlaid by post-mineralisation andesite, however the rhyolite host rocks are exposed at the surface locally. The geology of the Wharekirauponga resource and Area 1 is shown in Figures 8 and 9 below. Figure 8: Sectional geology through Wharekirauponga (WSP 2022b). 2 For New Zealand consenting purposes only.
