China Vanadium Titano-Magnetite Mining (HKG:0893) has provided further details on the renewal of its master guarantee agreement with Chengyu Vanadium, according to a Thursday filing to the Hong Kong bourse.

Shares of the company were up about 6% in late-morning Friday trade.

The guarantees, originally issued in 2010, 2013, and 2014, continue to expose it to contingent liabilities linked to its former subsidiaries, Huili Caitong and Xiushuihe Mining, which were disposed of in 2019.

While efforts have been made since their 2019 disposal to negotiate a discharge with lenders, no settlement has been reached, and financial institutions have insisted on full repayment before releasing the guarantees.

China Vanadium reiterated that counter indemnities remain in force under the renewed 2025 agreement.

The company also highlighted enhancements to internal controls and oversight, including bi-monthly meetings with the Huili Caitong Parties and a strengthened guarantee monitoring framework.
