Mining in New Zealand
New Zealand's gold mining history dates back to the mid 19th century, when it formed the financial backbone for the country's development. Today, New Zealand is still endowed with significant gold deposits and has two large operating gold mines in the Martha gold mine at Waihi, and Macraes gold mine in Central Otago. The Martha gold mine alone has yielded over 7.6 million ounces of gold and about 40 million ounces of silver since the 1880s.
- Production: 1878 to 1952: 4.9 Moz Au and 29.9 Moz Ag (1)
- Production: 1988 to 2011: 2.7 Moz Au (2) and 13.1 Moz Ag (3)
Gold Mining Industry
- two producing operations:
- Macraes, Otago, South Island (OceanaGold)
- Martha, Waihi, North island (Newmont)
- brownfields exploration in vicinity of these operations
- no major greenfields exploration programmes for 10-15 years prior to Glass Earth Gold Limited beginning operations in 2005
- Limited application of modern developments in exploration technology
- New computer developments, software, GPS etc not applied
- Vast amounts of existing data
- No new exploration data sets collected or collated
- Large, highly prospective areas available for exploration
- Glass Earth has moved rapidly to acquire large tracts of land in and around the most prospective areas
