Huge Volcanic GOLD NUGGETS
Metal detecting volcanic gold nuggets on the island of Papua New Guinea.
Up until 1970, there was little mineral extraction in Papua New Guinea. Since the 1970s, mineral extraction has dominated the national economy. With the exception of the Ok Tedy Mine (copper-gold) almost all of the mining in PNG has been gold mining.

From Wikipedia, the free encyclopedia:
The two largest gold mines are the Porgera (Enga Province) and Lihir (New Ireland Province) mines. In 2009, the Hidden Valley gold and silver mine (Morobe Province) commenced production. 2010 will see the start of production from the Ramu nickel-cobalt mine.
All the mining activity that has taken place in the country since 1970 has produced approximately 5 million tonnes of copper between 1970 and 2007. The country produced 202,277 t of copper in 2003 compared to 211,315 in 2002, all of which was produced by the Ok Tedi Mine the most active mine in the country. The mine reported that 29.32 Mt of ore was mined (approximately 240,000 t/d material moved) and 29.26 Mt milled (77,000 t/d) with a head grade of 0.78% Cu and 0.8 g/t Au. Respective gold and copper recoveries for 2003 at Ok Tedi were 68% and 84%.
The Ok Tedi Mine is an open-pit copper and gold mine in Papua New Guinea located near the headwaters of the Ok Tedi River, in the Star Mountains Rural LLG of the North Fly District of the Western Province of Papua New Guinea.
The mine is operated by Ok Tedi Mining (OTM), which is majority-owned by the PNG Sustainable Development Program Limited (PNGSDPL). In 2013 it was nationalised by the Government of Papua New Guinea in controversial action. Prior to 2002, it was majority owned by BHP Billiton, the largest mining company in the world since a merger in 2001.
Located in a remote area of PNG, above 2,000 m (6,600 ft) on Mount Fubilan, in a region of high rainfall and frequent earthquakes, mine development posed serious challenges. The town of Tabubil was built to serve the mining operation.
