Gold-quartz was discovered in 1850, when the Gold Tunnel vein was found. However, important production of lode gold did not commence until the early 1860s because of difficulties in milling the ore. By 1865, the output from lode-gold mining was averaging $500,000 per year and later ranged from $300,000 to $600,000.
