  • KGHM silver certified by the London Base Metals Exchange

    KGHM silver certified by the London Base Metals Exchange

    The copper giant is one of the world’s most trusted silver producers. KGHM Polska Copper S.A. has been certified for the next consecutive year by the London Base Metals Exchange (LBMA) for responsible silver production in 2022. The certificate confirms Polish Copper’s compliance with the requirements set out in the LBMA Responsible Silver Guidance and allows it to gain entry to the LBMA’s prestigious Good Delivery list of the world’s most trusted silver producers.

    – The highest quality of both the product and the entire production process is the strength of the KGHM brand. Our customers know that we are a trusted partner who adheres to the highest standards throughout the supply chain. The LBMA certificate confirms that it is not a matter of declarations, but of actual actions – said Tomasz Zdzikot, CEO of KGHM Polska Miedź S.A.

    EXORBITANT STANDARDS

    The LBMA’s guidelines for responsible sourcing of gold and silver are designed, among other things, to combat human rights abuses and the financing of terrorism, avoid supporting military conflicts and ensure compliance with the highest possible anti-money laundering standards. The guidelines recommend the use of a five-step, risk-based supply chain examination procedure, in line with the OECD Guidelines for a Responsible Supply Chain for Minerals from Conflict and High-Risk Areas.

    As part of the certification process, an attestation service by an independent, LBMA-accredited auditing firm (PricewaterhouseCoopers Poland) was required. A positive assessment of KGHM’s procedures for the production, storage and sale of silver, as well as of the Policy and Procedure for a Responsible Supply Chain for Gold and Silver of KGHM Polska Miedź S.A. provided the basis for the auditor’s positive recommendation to award the certificate.

    SILVER MARKET LEADER

    KGHM has been on the podium of global silver producers for years. According to the World Silver Survey 2023, it ranks first in the list of “largest silver mines in the world”. In the category of “largest silver producers”, the copper giant was ranked second. Polish Copper produced 1,298 tonnes of silver in 2022.

    KGHM sells silver in the form of pig sow and granulate. Silver customers include, among others, financial institutions, the jewellery industry, the electronics and electrical industry, the photovoltaic industry, catalyst manufacturers and coin, bar and medal producers. Around 16% of the copper giant’s revenue comes, precisely from the sale of silver.

    FROM BLACK MUD TO SHINY PIG SOW

    Silver production at KGHM is carried out at the Głogów smelter, in the Precious Metals Division. PMD was established exactly 30 years ago specifically to recover the precious metals – silver and gold – present in the copper ore. These are found in the so-called ‘black mud’, i.e. the anode slime produced during the electrorefining of copper. From cathode silver with an Ag content of more than 99.99 per cent, metallic silver is produced in the form of granules packaged in 25 kg bags and pig sows of approximately 1,000 troy ounces, which amounts to about 31.1 kg.

    In June, the key connection between the shaft and the Rudna Mine was made.

    The technical connection, i.e. the merge of excavations from the Rudna Mining Plants to the GG-1 shaft, was successfully carried out on June 14 this year. Work is now underway there, which will allow new amounts of fresh air to be supplied to the mine workings. This will definitely improve working conditions underground.

    The shaft is ready to build reinforcement and equip with the necessary installations and equipment for the target period. A three-meter layer of concrete has been poured on the bottom. The two basic parameters of the GG-1 shaft are: depth – 1,348 meters, and the diameter in the light of the casing, which is 7.5 meters. It is an intake-air shaft that will be used to transport people and materials.

    KGHM is a jewel in the crown, and the GG-1 shaft is an amazing project that will affect the safety of miners. I am full of admiration for all those who undertook this project. Everything is done so that miners can work in the best possible conditions. The GG-1 shaft is also a business, industrial, economic project. These are copper deposits that can be mined for decades to come,’ said Elzbieta Witek, Speaker of the Polish Parliament.

    The GG-1 shaft is a strategic investment by KGHM. It will provide the air that will enable us to exploit the Glogow Gleboki-Przemyslowy deposit at depths that were previously inaccessible to us. We are a global company, but domestic production is of fundamental importance to the company. The completed shaft, first of all, ensures safety, but also promotes more efficient work by miners,’ said Tomasz Zdzikot, Chairman of the Management Board of KGHM Polska Miedz S.A., during a press conference.

    The GG-1 shaft is of fundamental importance for the development of KGHM Polska Miedz S.A.. It will make it possible to open up new areas of the copper deposit and prolong the operation of the Polkowice-Sieroszowice and Rudna mines. The investment will also improve ventilation and air-conditioning conditions for miners and will shorten the routes of crews’ access to the pits.

    Shaft in numbers

    The GG-1 shaft complex is being built as part of the Deposit Opening Program conducted by the Department of Mining Structure Development at KGHM Headquarters. The work was carried out by a KGHM Group company, PeBeKa. The GG-1 shaft is one of the most important facilities that will serve to open up the Glogow Gleboki-Przemyslowy Mining Area

    The estimated industrial copper ore resources are nearly 265 million tons, with an average copper content of 2.40 %. This represents about 25 % of copper resources and more than 30 % of silver resources in all KGHM license areas in Poland. Access to these resources will secure the continuity of copper ore mining for many years to come.

    According to investment plans, in the years 2028-35, i.e. during the period of the greatest intensity of mining work, production from the Glogow Gleboki-Przemyslowy area is expected to be 10-11 million tons of ore, from which it will be possible to obtain about 200-220 thousand tons of electrolytic copper per year.

    History of the investment

    Construction of the GG-1 shaft began in 2010. Two years later, the shaft tower, which is one of the tallest ever erected by KGHM, began to be built. It is 45.5 meters high and weighs 1,100 tons. The equipment used in pilling the shaft includes a complex hoisting system with more than a dozen steel cables. Each more than 1,500 meters long, some weighing as much as 20 tons.

    In 2013, one of the key stages of construction began: the freezing of the rock mass preceding the shaft pilling. Brine was then flowed into 40 freezing holes. The first bucket of excavated material left GG-1 on December 11. A year later, specialists reached layers of solid rock at a depth of 393 meters. It was then that the method of shaft pilling was changed from mechanical excavation of the rock mass to the blasting method.

    To build up the first section of GG-1, PeBeKa employees used 466 iron rings, which protected the shaft from flooding with water from Tertiary and Triassic layers. To comprehensively protect GG-1 from the effects of water inflow, a modern so-called cascade drainage system was installed in the shaft. In subsequent years, as work progressed on further pilling the shaft, further elements of the drainage system were added. A total of eight stations were built there, pumping water cascading from the bottom of the shaft to the surface.

    This year, March also marks the 60th anniversary of the mining of the first cup of copper ore in the Copper Belt. It happened on March 20, 1963, in the L-III shaft belonging to the Lubin mine. One of the pioneers of Polish Copper, the late Jan Urlich recalled, ‘among the ore, we noticed a large chunk of dolomite, in which large veins of copper sulfides were visible. The joy was enormous. I thought: at last we have reached the deposit.’

    Shaft GG-1 is the company’s thirty-first shaft in the Copper Belt. Meanwhile, preparatory work has begun on the construction of another important facility in the Deposit Opening Program in the Glogow Gleboki-Przemyslowy and Gaworzyce mining areas. The GG-2 shaft, located in the municipality of Zukowice, will have an exit-material function.[/vc_column_text][distance desktop_type=”30″][/vc_column][/vc_row][/vc_section]
