Seven months after the attacks on the company's mining facilities, mining company Gemrock announced on Wednesday that it has resumed ruby mining activities in Cabo Delgado.

At a press conference in Pemba, Gemrock founder Ian Charles Hannam announced the return, stressing that: "we are very grateful for the support the government has provided to increase security".

"They gave us defense and security forces to increase security in the area and we, as a company, are also going to increase that security," said Hannam, quoted by Lusa, explaining the use of drones, dog guards and other electronic means.

For his part, Gemrock's chief operating officer, Colin John Andrews, said that the company's shutdown had caused huge losses and that there was no income "to pay employees".

Gemrock is one of the companies mining rubies and graphite in Cabo Delgado province.
