Unprocessed lithium ore belonging to Xingfeng Investment, estimated to be about 90,000 metric tonnes, has been deposited at the Walvis Bay harbour in the past week.

This is despite the Ministry of Mines and Energy indicating that Xingfeng does not possess a removal or transport permit for lithium.

When nbc News arrived at the Walvis Bay port, a heap of unprocessed lithium ore estimated to be about 90,000 metric tonnes was visible.

It is alleged that the lithium ore was transported from the Xingfeng Investment mine near Omaruru to the harbour, to be exported by a vessel in November.

It is, however, not clear about the origins of lithium ore because unconfirmed reports say that Xingfeng transported the raw material from their other mine at Uis and crushed it at the Omaruru mine.

The company representatives refused to comment on the matter when contacted for a response.

Meanwhile, the Mines and Energy Ministry has approached the Erongo Police to stop any truck transporting unprocessed lithium ore from the mine near Omaruru because the company does not have a removal or transport permit.

Mining Commissioner Isabela Chirchir said although Xingfeng got permission from the high court to continue mining after the minister revoked their licence in April, no permission was granted to export.

However, in a letter from Attorney General Festus Mbandeka, the Mining Commissioner was advised to grant the company permission to export at least 55,000 metric tonnes of lithium ore for testing purposes.

The Erongo Police say the request from the mining commissioner is receiving the highest attention, and officers have been deployed to monitor the road for trucks transporting unprocessed lithium ore to Walvis Bay.

The Head of Community Affairs, Inspector Ileni Shapumba, told nbc News that the officers have been monitoring the situation since Monday, and no trucks were observed transporting lithium ore on the roads.
