ASX-listed Walkabout Resources says its Lindi Jumbo graphite mine, in Tanzania, was only mildly impacted on by heavy rains and a brief power interruption as a result of cyclone Hidaya, which passed over the country over the weekend. However, the coastal road from the project to the capital Dar es Salaam has suffered damage and, while there are alternative routes to transport graphite to port, this will involve significantly longer trucking distances.
