Black Rock Managing Director John de Vries commented:

“We are pleased to award the bulk earthworks contract to Taifa Mining and Civil, a leading Tanzanian contractor. This award follows a competitive tender process and demonstrates our commitment to local content compliance and delivering value for the Project.

“By structuring the contract into two phases, we can proceed immediately with the critical diversion of the Mdindo stream followed by the main body of the earthworks. This is a vital de-risking step that clears the path for the main construction phase. It ensures that once our Final Investment Decision is made, the site is physically ready for a rapid transition into full-scale construction.

“The pricing we have secured is consistent with our FEED estimates, further validating the robust economics of the Mahenge Graphite Project as we move toward execution.”
