RE:Copper - Silver?Poland and Peru. If silver comes with coper it could be one of those mine aru can find Polkowice-Sieroszowice, Poland
The Polkowice-Sieroszowice mine located in the Legnica-Glogw Copper Belt of Poland is the second biggest silver mine in the world. The copper-silver mine, which is owned and operated by state-owned mining enterprise KGHM, produced more than 14Moz of silver in 2012. The proven and probable silver reserves of the mine were estimated at 545Moz as of December 2011.
Polkowice-Sieroszowice is an underground mining operation that uses blasting to extract ore from the Polkowice, Sieroszowice and Radwanice deposits. Extracted ore is processed at the Polkowice-Sieroszowice mining plant which has been in operation since 1996. The mine’s total contained silver reserves stand at 775Moz, including its share of reserves in the Deep Glogw deposit located adjacent to it. KGHM plans to mine 50% of the Deep Glogw deposit through the Polkowice-Sieroszowice operation.
Lubin, Poland
Lubin mine, located 347km south-west of Warsaw, Poland, ranks as the fifth biggest silver mine in the world. The mine was estimated to contain 442.4Moz of silver, including 254.8Moz of proven and 187.6Moz of probable silver reserves as of December 2011. The copper-silver mine is one of the three mines owned and operated by KGHM in the Legnica-Glogw copper basin of Poland.
Lubin mine has been operational since 1968. It is an underground mining operation extracting ore from the Lubin-Malomice deposit discovered in 1957. It is comprised nine working sections at a depth of 610m to 850m. Room-and-pillar method with hydraulic backfill is used for the mining. The extracted ore is sent to the ore enrichment plants. The mine produces approximately 13Moz of silver per year.
Rudna, Poland
Rudna, another mine owned by KGHM in the Legnica-Glogw copper belt of Poland, ranks as the sixth biggest silver mine in the world. The copper-silver mine was estimated to contain 357Moz of silver, including 242.8Moz of proven and 114.2Moz of probable silver reserves as of December 2011. It has been operational since 1974 and produced more than 21Moz of silver in 2011.
The mine exploits the copper and silver resources of the Rudna mineral deposit. It is an underground mining operation consisting of 11 shafts and 13 mining sections at a depth of 950m to 1,150m. It employs room-and-pillar method with hydraulic backfilling. The extracted ore is sent to the Rudna Concentrator for processing. KGHM plans to mine half of the neighbouring Deep Glogw deposit through the Rudna operation. The reserves of Rudna and 50% of Deep Glogw, if combined, will be 587Moz, making it the third biggest silver mine in the world.
Antamina, Peru
Antamina mine, the ninth biggest silver mine in the world, is located 200km from the city of Huaraz in the Andes Mountains of Peru. The copper-zinc mine produces silver and lead concentrates as byproducts. The mine’s proven and probable silver reserves as of December 2012 totalled 285.7Moz. Compania Minera Antamina, a joint venture between BHP Billiton (33.75%), Xstrata (33.75%), Teck (22.5%) and Mitsubishi Corporation (10%), owns and operates the mine.
Antamina commenced commercial production in 2001. It includes an open-pit mining operation using trucks and shovels. The extracted ore is sent for processing to the concentrator plant at Camp Yanacancha. The milling capacity of the plant was increased to 130,000tpd in 2011. The mine produced 11.7Moz of silver in the financial year ending June 2013. Antamina has an estimated mine life of 14 years.
