Slide 26: Golden Blocks, the Forgotten High Grade Gold Mine
Golden Blocks, the Forgotten High Grade Gold Mine P.V.M. Angus1, M.D. Howard2 1 ARC Ltd, 18 Princes St, Dunedin paul.angus@xtra.co.nz 2 Strategic Elements Ltd, 138 Churchill Ave, Perth matthew@strategicelements.com.au For personal use only Abstract The quartz lodes at Golden Blocks are very similar
Slide 27: For personal use only
Golden Blocks located in NW Nelson (Figure 1) is considered a northern extension of the Reefton and Lyell Goldfields where over 2.6Moz of gold has been produced form largely narrow vein quartz lodes with very similar para-genesis to Golden Blocks. The primary insitu gold grade at Reefton is around 2
Slide 28: Regional Geology
Regional Geology The terranes that make up New Zealand’s basement are divided up into a Western Province, composed of the Buller and Takaka Terranes (Figure 1), and an Eastern Province, composed of the Brook Street, Murihiku, Dun Mountain-Maitai, Caples, Torlesse Composite (Rakaia and Pahau), and Wa
Slide 29: For personal use only
The Western Belt contains the Greenland, Golden Bay and Aorere Group quartz-rich greywacke, sandstone and black slate, of mainly Ordovician age and host shear-zone gold quartz lodes at Golden Blocks, Lyell and Reefton. The lithological content and structural style for all three areas are very simila

that were very close to this fault zone and this fault may have been important in the localisation so the mineralisation. For personal use only A B A C D Figure 3.

Within the Reefton the metasediments have tightly folded into a broad structural corridor that extends along the length of the goldfield. The fold hinge zones are often sheared and contain the majority of the historic mines. The Cranz Creek Shear Zone lies approximately 1km to the east of the main h

with the south plunging axis of an F2 fold. At Reefton the ore shoots generally dip shallowly to the north parallel to the north dipping F2 folds. The gold mineralisation is interpreted to occur towards the end of the main folding (F2) and low grade metamorphic events. The gold mineralisation's is s

Slide 35: For personal use only
Bishop (1932) the former government Inspector of Mines who inspected the Aorangi mine multiple times in his official capacity reported that “I am of the opinion that the strength and continuity of the reef in the upper workings entirely justifies the expectation of it living to greater depths”. He a
