The line turned solid again about 10km to my north west, where another quartz reef mine was located. In between the solid lines was a dotted line, supposedly to represent where the geology suggests that the quartz reef would likely occur. That dotted line goes through my property and almost exactly over my hill where I found the quartz outcrops.

Quartz Reef Tailings | Central Otago NZ
Quartz Reef Tailings, also known as Northburn Tailings is a short up-hill walk, 8km from Cromwell. Walk by herringbone shaped stacked rock heaps, a Chinese stone hut, and gold mining tailings. This relic of Central Otago's gold mining days is virtually unmodified since being abandoned many years ago.

Quartz Mining and Extraction | Quartz Mining Processing
In underground mining,the quartz crystals are identified by the different mining methods like shaft and tunnel mining, roof and pillar mining and through the slope mining. For the extraction of the crystal, the rock which comprises the quartz crystal is allowed to decompose in the process of weathering. As quartz is the most resistant component ...
