Beiya Gold Deposit,Heqing County,Yunnan——One of China's Ten Biggest Gold Deposits
摘要
The Beiya gold polymetallic ore district covers an area of 22.06 km2 and is located 47.5 km away in the direction 172° from Heqing county seat of northwestern Yunnan. Its geographical coordinates are 100° 11 ′15″-100° 13′00″ E and 60°07′30″26°10′30″ N. Since its discovery in 1999 until November 31st 2013, it has had accumulative proven （111b＋122b＋331 ＋332＋333） gold metal amounts of 258.475 t at an average grade of 2.61 g/t. This deposit contains 88.98 million tons of paragenetic and associated iron ores, with TFe grade varying from 9% to 36%; metal amounts are： gold 27 t; copper 0.6188 million tons; silver 5439 t; lead 1.35 million ton; zinc 0.31 million ton; and sulfur content is 10.09 million ton. Beiya is one of the top ten largest gold deposits discovered in recent years in China.
