EQ Resources has started a water transfer program at its Barruecopardo tungsten mine in Spain, moving water from the lower section of the open pit to a newly completed Northern In-Pit Sump. The company said the initiative is intended to restore access to higher-grade ore within Phase 5. EQ Resources stated that the update does not involve a major acquisition, exploration discovery, or resource upgrade, but it is tied to near-term production planning.
The lower pit at Barruecopardo has historically supplied some of the highest-quality feed to the processing plant. Mining access in this area has been limited by accumulated water, requiring dewatering before extraction can continue. EQ Resources reported that approximately 84,968 cubic metres of water currently remain within the pit.
Northern In-Pit Sump and water relocation requirements
EQ Resources said about 68,968 cubic metres of water must be relocated before mining crews can regain full access to the targeted Phase 5 ore zone. The company completed construction of the Northern In-Pit Sump to manage pit water levels and support ongoing development work. The sump was designed with storage capacity of approximately 120,000 cubic metres.
The company’s update linked the sump capacity to operational flexibility during the transfer period. It also indicated that effective water management and pumping infrastructure are required to enable the planned mining sequence for Phase 5. EQ Resources said these elements are central to timing ore extraction and maintaining feed quality for the processing facility.
Pumping system capacity for dewatering
EQ Resources reported that installed pumping systems can transfer roughly 300 cubic metres of water per hour. With an assumed operational availability rate of 95%, the system is expected to move approximately 6,840 cubic metres per day. On that basis, the dewatering program is described as a short-term operational process rather than a major long-term constraint.
The company said execution remains important because it affects when higher-grade material can re-enter the mine plan and supply the processing plant. EQ Resources also stated that mining continues in other active sections of the open pit during the dewatering period. As a result, it characterized the activity as targeted work focused on unlocking Phase 5 rather than a restart of suspended operations.
Phase 5 ore inventory and expected plant feed timing
Phase 5 contains an estimated 1,028,088 tonnes of planned ore. EQ Resources said this equates to around 192,758 MTUs at an average grade of 0.187% WO₃. The company’s update highlighted that ore grade is a key economic driver for tungsten producers.
EQ Resources stated that higher-grade feed can improve processing efficiency, increase metal recovery rates, reduce unit production costs, and support stronger operating margins and more consistent plant performance. The company expects material from Phase 5 to begin contributing to processing plant feed from the end of June 2026.
Tungsten portfolio context and regional critical minerals relevance
Barruecopardo is part of EQ Resources’ global tungsten portfolio, which also includes the Mt Carbine mine in Queensland, Australia. EQ Resources said Barruecopardo’s significance extends beyond production figures in the context of critical raw materials security priorities by governments and manufacturers. The company described Spain’s mine as an important domestic source of tungsten for European industry.
Tungsten uses cited by EQ Resources include industrial manufacturing, mining equipment, defense applications, cutting and drilling tools, advanced engineering, and high-tech industries. The company said Europe’s efforts to reduce dependence on imported critical minerals support continued relevance for Barruecopardo within regional supply chains.
Operational factors affecting production outcomes
EQ Resources’ update emphasized that mining performance depends on more than resource size alone. It cited factors including pit water control, pumping infrastructure, sump capacity, mine sequencing, haulage access, and processing plant integration as elements influencing production outcomes at Barruecopardo.
The company said completion of the Northern In-Pit Sump enables access to a valuable ore body targeted for improved feed quality and operational efficiency. EQ Resources Managing Director Craig Bradshaw described initiation of pumping as an important step toward restoring access to lower-pit ore zones.
The company expects the completed water transfer program to support renewed flow of higher-grade material to the processing plant over subsequent months. EQ Resources said investors should focus on project execution through key inputs including Northern In-Pit Sump capacity of 120,000 cubic metres, a required water transfer volume of 68,968 cubic metres, access to more than 1 million tonnes of ore in Phase 5, and an average grade of 0.187% WO₃.
