CONCLUSION Alluvial mining in Australia was the product of technology transfer and innovation, but it was also inherently conservative. Technology was transferred spatially as the result of the migration of experts who passed on their skills to others, but the miners were successful because they were able to draw on and maintain ancient traditions.
Hill 50, now held by Ramelius, near Mt Magnet in WA, began life as an alluvial gold find in 1891 and was one of Australia's deepest gold mines during its heyday at 1.5km deep, churning out over 2.1m ounces of gold.
