    NMMC Connects Skip and Main Shafts at Zarmitan Deposit to Enhance Operations

    NMMC JSC has successfully connected the skip and main mine shafts at the Zarmitan deposit, reaching a depth of 1,000 metres. This significant milestone is part of the company’s investment project aimed at developing the lower horizons of the deposit. The newly commissioned skip mine shaft, which has a diameter of 6.5 metres, was inaugurated in April this year. The extension of the main shaft to the same depth has now been completed, allowing for improved operational efficiency and safety measures.

    The connection of these two shafts is expected to enhance the supply of fresh air to the underground sections of the Zarmitan deposit, which is crucial for maintaining a safe working environment for miners. Additionally, this connection will serve as a backup emergency exit, further bolstering the safety protocols in place at the mine. The construction work on the main shaft is anticipated to be finalised by the end of the current year, marking a significant advancement in the mining operations at Zarmitan.

    This development underscores NMMC’s commitment to modernising its mining infrastructure and improving operational safety standards. As the mining industry continues to evolve, such investments are vital for sustaining productivity and ensuring the well-being of workers underground. The Zarmitan deposit, known for its rich mineral resources, is poised to benefit from these enhancements, which will facilitate more efficient extraction processes in the future.

    Navoi Mining & Metallurgical Combinat Expands Modernisation Drive with Major Shaft Development at Zarmitan

    Navoi Mining & Metallurgical Combinat (NMMC) is accelerating its modernisation strategy with a series of major investment projects designed to boost ore production, improve mining efficiency, and create new employment opportunities across the region. The company’s latest achievements highlight its growing role as a technological leader in Central Asia’s mining sector.

    A key milestone is the “Lower Horizons Development of the Zarmitan Deposit” project. In April 2025, NMMC commissioned the new “Skipovoy” shaft — a 6.5-metre-diameter, 1,000-metre-deep vertical shaft enabling the hoisting of 1,500 tonnes of ore per day. This high-capacity shaft has already generated 90 new jobs and provides critical new infrastructure for accessing deeper ore reserves.

    The parallel “Glavny” shaft has also reached the 1,000-metre mark. Once completed, it will support essential functions including ore hoisting, personnel and equipment transport, groundwater pumping, and ventilation of the underground mine network.

    The project has benefited from international cooperation: NMMC engineers worked with the Czech firm Mine Construction Alliance s.r.o. to link the “Skipovoy” and “Glavny” shafts at the 0.00 m level. This connection improves underground air circulation and establishes a secondary access route, strengthening operational safety and resilience.

    Key outcomes of these advancements include enhanced mining efficiency, expanded access to deeper ore bodies, and greater economic opportunities for local communities.

    Construction of the “Glavny” shaft is expected to be finished by the end of this year, marking another major step in NMMC’s comprehensive modernisation programme.
