Name: Lubin mine.

Location: Lubin is located in south-west Poland, on the northern border of Lubin, in Lower Silesia.

Controlling Company: KGHM.

Brief Description: The Lubin mine is the oldest mine in the Polish Copperbelt, and comprises the Lubin-Małomice deposit. The mine extracts polymetallic ore containing mainly copper and silver, and nickel, cobalt and molybdenum in small amounts.

Operations are conducted over 158 km² the Eastern, Central and Western regions.

Brief History: The Lubin-Małomice deposit was discovered by a team led by Jan Wyżykowski in March 1957. The discovery of the deposits led to the construction of Zakłady Górnicze – the Lubin mining site – in January 1960. 

The mine started its operation eight years later and reached its full production capacity of 4.5-million tonnes a year of ore in 1972. After the expansion of the mine a year later, its capacity increased to 7.6-million tonnes of copper ore a year. It continued at that rate until 2012. Year 2013 saw an increase to 7.8 million tonnes. The mine’s current production capacity is estimated at about eight-million tonnes a year of ore.

Products: Copper and silver.

Geology/Mineralisation: The Lubin-Małomice deposit is classified as a sediment-hosted stratiform copper deposit, characterised by intensive tectonical displacements within the orebody, especially in the south-west. The deposit is shallow, under loose Cainozoic sediments but with a dense grid of faults and big displacements. In areas with such intensive tectonic events exploitation, is very difficult and in some cases, impossible. The depth where the copper orebody occurs ranges from 368 m to 1 006 m.

Reserves: Total proven and probable reserves as at December 31, 2014, were estimated at 339.13-million tonnes grading 0.95% copper and 40.1 g/t silver.

Resources: Total mineral resources as at December 31, 2014, were estimated at 378.89-million tonnes grading 1.32% copper and 54.87 g/t silver.

Mining Method: Room-and-pillar, using natural roof settlement and hydraulic backfill.

Major Infrastructure and Equipment: There are seven shafts 494 m to 963 m deep. One is an extraction shaft, while the rest are used for material transport and ventilation purposes. The mine includes a seven-million-tonne-a-year concentrator that uses rod mills for primary grinding and ball mills for secondary grinding, mechanised drilling rigs, scalers, rockbolters, load-haul-dump units and haulage trucks.

Prospects: None stated.
