Mining gold from the hard rock deep in the earth proved tricky. Experienced miners from Cornwall, England, immigrated by the hundreds. Wellversed in hardrock tin and copper mining, the Cornish miners brought such advancements as the "Cornish pump" that helped empty underground tunnels of water that flooded into mine passages from underground springs. With Cornish miners' supervision ...

Hardrock mining was on a small scale only, and most mines consisted of a few hundred metres of tunnels and a stamping battery. The total historical hardrock production from Otago was less than 20 tonnes of gold. Some of the ore production from several of the mines (, Macraes, Bendigo, Barewood) was directed at scheelite, not gold. Modern mining is at a much larger scale and can .
Although hardrock producers have lower costs, the price they receive for their end product, usually spodumene concentrate, is significantly lower than that received for lithium carbonate, chloride and hydroxide, which are produced at brine operations. In 2019, lithium concentrates are expected to achieve an average price of US4,619/t LCE, 57% lower than the price expected for lithium ...
