Sinomine can export another 300,000 tonnes as its planned sulphate plant runs beyond the deadline for ending concentrate exports

* Sinomine’s 2026 Bikita export allocation has increased to 500,000 tonnes
* Its 100,000 tonne annual lithium sulphate plant is expected around mid 2027
* Zimbabwe shipped 1.13 million tonnes of spodumene concentrate to China in 2025

Zimbabwe has granted Sinomine Resource Group an additional quota to export 300,000 tonnes of lithium concentrate from Bikita Minerals, extending shipments from one of the country’s largest producers as the January 2027 deadline for ending concentrate exports approaches.

According to a Reuters report, Sinomine disclosed the additional allocation in its half-year results after receiving an initial 200,000 tonne quota in April. The latest approval takes Bikita’s 2026 export allocation to 500,000 tonnes and allows the mine to maintain supply to Sinomine’s downstream operations in China following export disruptions between February and April. 

The numbers expose the immediate execution gap in Zimbabwe’s beneficiation programme. Government plans to prohibit lithium concentrate exports from January 2027, while Sinomine expects its 100,000 tonne annual lithium sulphate plant at Bikita to be completed around mid 2027. Bikita therefore approaches the deadline with substantial concentrate production capacity and its next processing stage still under construction. 

Sinomine operates two plants at Bikita with combined capacity of 600,000 tonnes of spodumene and petalite concentrate. A technical upgrade is expected to lift annual spodumene concentrate capacity to 400,000 tonnes. The additional export quota preserves a route to market for this existing capacity while the sulphate investment advances. 

The capacity mismatch extends across the sector. Zimbabwe’s lithium producers asked authorities in June to consider moving the processing deadline to around June 2027 as several plants remain under development. Bikita and Sichuan Yahua’s Kamativi operation are building lithium sulphate facilities, while state-owned Sandawana was undertaking a processing feasibility study. The industry forecasts annual lithium sulphate production reaching 344,000 tonnes by 2030. 

Government has maintained the January 2027 deadline. Mines Minister Polite Kambamura reiterated in July that producers should prepare for implementation as scheduled. That position meets a physical constraint because Zimbabwe currently has only one operating lithium sulphate facility, and its available capacity is already committed to its own mine production. 

Zhejiang Huayou Cobalt completed the country’s first lithium sulphate plant at Prospect Lithium Zimbabwe at a cost of US$400 million. The 50,000-tonne annual facility shipped its first lithium salts in April 2026, establishing commercial evidence that another stage of lithium conversion can operate locally. Prospect has also said the plant cannot absorb third-party concentrate because its capacity is matched to production from its own concentrator. 

Bikita consequently needs its own processing investment to close the gap. The measure of progress now moves from announced capital expenditure to construction completion, commissioning, plant utilisation and the volume of concentrate converted domestically.

Zimbabwe’s recent export performance provides the economic context for that transition. The country shipped about 1.13 million tonnes of spodumene concentrate to China in 2025, supplying roughly 15% of Chinese lithium concentrate imports. Chinese companies have invested about US$2 billion in Zimbabwean lithium mining and processing since 2021, establishing substantial mine capacity and linking the country closely to China’s battery supply chain. 

The policy objective now requires a larger portion of that mineral flow to undergo chemical processing inside Zimbabwe. Lithium sulphate adds another industrial stage before further refining into battery grade lithium carbonate or hydroxide. Its economic contribution will depend on commercial utilisation, conversion costs, realised product prices and the value of processed exports.

Sinomine’s latest quota sits directly inside this transition. The 500,000 tonnes approved for 2026 preserve production and export continuity while Bikita develops domestic conversion capacity. The quota therefore carries an implicit expiry test. Its economic rationale weakens as the sulphate plant reaches commercial production and more Bikita material can be processed locally.

That test also applies to the wider quota system introduced after government temporarily halted concentrate exports in February over alleged malpractice and mineral leakages. Authorities subsequently allowed shipments to resume under producer-specific allocations and processing commitments. The regime provides a bridge between an established concentrate-export industry and the processing capacity government wants operating from 2027. 

The remaining months before January will test whether that bridge is long enough. Bikita’s reported mid 2027 completion date extends beyond the policy deadline. Kamativi is also still developing its facility, while the existing Prospect plant has no spare third-party capacity. Producers reaching January without operating sulphate plants will therefore face limited domestic processing options under the current industry structure. 

The available evidence does not establish that government will postpone the deadline. It establishes a measurable capacity gap that authorities and producers have several months to resolve.

For Zimbabwe, the success of beneficiation can be tested through commissioned processing capacity, utilisation rates, processed export volumes and the foreign currency earned from those products. For Sinomine, the immediate milestones are clearer. Bikita needs to complete its sulphate facility, commission it successfully and begin moving a growing share of mine output through domestic conversion.

The additional 300,000 tonne quota keeps Bikita’s existing production moving while that investment advances. It also leaves Zimbabwe’s lithium policy facing its most important execution test yet. By January 2027, the industry will need enough operating processing capacity to begin replacing the concentrate volumes that quotas are currently keeping on the road to export markets.
