Murowa Diamonds has embarked on an ambitious exploration programme meant to give the Mberengwa mine another 3-year lease of life.
The Rio-Zim owned diamond mine has expressed reservations that in 18 months time the lifespan of its entity might come to an end.
The company said it has therefore increased exploration at its two sights in Zvishavane and Masvingo in order to ensure continued operations.
Murowa board chairman Mr Lovemore Chihota told the visiting Parliamentary Portfolio Committee on Mines and Energy that the company has invested hugely in exploration.
While the Portfolio Committee toured Murowa Diamonds, it was appraised also of the operations and challenges the company is facing.
The mine management also presented contentious issues of high royalties and ground rental fees charged by government.
The management sought for intervention from the committee through the legislature.
