DRC-focused gold producer Banro is investigating the possibility of establishing underground mining under the existing open pits at its Twangiza and Namoya mines.

The announcement was made in its Q2, 2017 financial results which delivered poor production performances from both mines.

Banro says adit access by horizontal or nearly horizontal shafts would be employed due to the mines favorable topography,  which could be less capital intensive than typical underground mining operations.

This will further minimize costs through improving operating efficiency and optimising operating procedures. Resulting in increased production and processing capacities while maintaining economic benefits and strong environmental and safety standards.

Operational performances

During the second quarter of 2017, the plant at the Twangiza mine processed 386 295 t of ore (compared to 414 829 t during the second quarter of 2016).

Namoya’s operations were interrupted by two security incidents during the second quarter of 2017. The impact included the loss of 8.5 days of mining operations.

The delivery of the new mining fleet in July 2017 is expected to assist in achieving higher levels of gold production.

Banro does not expect to reach its previously provided 2017 gold production outlook because of given on-going challenging operating environment due instability in the DRC.
