Name of the Project
Lindi Jumbo graphite project.

Location
South-east Tanzania.

Project Owner/s
Walkabout Resources.

Project Description
The Lindi Jumbo project has mineral ore reserves of 5.15-million tonnes grading 17.9% total graphitic carbon for 987 000 t of con­tained graphite.

The mine life has increased from 20 years in the 2017 definitive feasibility study (DFS) to 24 years in the enhanced DFS to produce 40 000 t/y of graphite.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The pretax net present value has increased from $302-million, at a 10% discount rate in the 2017 DFS, to $335-million in the enhanced DFS. The project’s pretax internal rate of return is estimated at 142% in the enhanced DFS, from 108% in the 2017 DFS. The payback period is less than two years.

Capital Expenditure
With the contracting of the power and camp scope changes, and the Lindi Jumbo plant construction nearing completion, the final estimated capital cost for the mine is $34.5-million, up from the $27.8-million estimated in the original DFS, Walkabout said on September 7, 2023.

The bulk of this cost was incurred in 2021.

Planned Start/End Date
The Lindi Jumbo project is preparing for operational readiness in early 2024.

Latest Developments
Lindi Jumbo has weathered funding delays with resilience, registering a minimal impact of 4.2% on the capital cost estimate, Walkabout Resources reported on October 31.

At the end of September, the final estimated capital cost for the mine was $34.5-million net of value-added tax. This includes scope changes of $3.8-million, with the bulk incurred in 2021.

Walkabout said that with the earthmoving and civils contract almost completed, and the engineering, procurement and construction (EPC) contract locked in at a fixed price, there was limited room for big changes in the expected total project costs owing to unexpected delays.

Key Contracts, Suppliers and Consultants
TNR (bulk earthworks civil engineering works contract); Yantai Jinpeng Mining Machinery (EPC); and Axis Group International (EPC oversight).
