On 14 April 2014, following a two year occupation at Merelani by armed illegal miners, Richland Resources announced the discontinuation of financial investment into Tanzania. Since the announcement TanzaniteOne Mining and Tanzania State Mining Corporation have worked in consultation with Richland Resources to manage costs, increase revenue and improve operations at Merelani to prevent a temporary mine closure while the Government secures the area. Following interdepartmental restructuring, 229 out of 670 TanzaniteOne Mining employees were identified for possible retrenchment, dependent upon the outcome of negotiations with Government.
The Tanzanian government has re-approved the use of X-ray body scanner machines, which are anticipated to be operational at Merelani by Q4 2014. The Government has also sent default notices to small scale miners to discontinue all illegal mining activities currently happening on Block C, at Merelani, as the mining license is owned 50:50 by TanzaniteOne Mining and the Tanzania State Mining Corporation.
