Name of the Project
Zulu lithium/tantalum project.

Location
Zimbabwe.

Project Owner/s
Premier African Minerals.

Project Description
A scoping study in 2017 evaluated the economics of developing an openpit mine and processing facility to directly produce spodumene and petalite concentrate.

The scoping study identified a target production of 84 000 t/y of spodumene concentrate and 32 500 t/y of petalite concentrate for an initial 15-year life-of-mine.

The 2021 updated scoping study is based on preliminary technical and economic assessments.

The updated scoping study has modelled three scenarios for different spodumene concentrate sales prices to illustrate the impact of the recent significant increase in prices of spodumene and petalite. No further changes have been made to the underlying economic, technical, engineering or processing assumptions used in the scoping study, the resources or the mine plan.

Overall, the improvement in spodumene pricing and, therefore, the revenue factors, have resulted in a significant positive improvement in the economic results, despite the escalated capital and operating costs.

Net Present Value/Internal Rate of Return
The project has a net present value (NPV), at a 10% discount rate, of $127-million in the 2017 scoping study and an internal rate of return (IRR) of 85.9%, with a payback of two years, based on prices of $800/t spodumene and $400/t petalite concentrate.

In the 2021 scoping study, the project has an NPV, at a 10% discount rate, of $207-million, $292-million and $377-million, based on spodumene concentrate prices of $1 000/t, $1 150/t and $1 300/t respectively, and petalite prices of $400/t.

In the 2021 scoping study, the project has a pretax IRR of 112.4%, 144.3% and 176%, based on spodumene concentrate prices of $1 000/t, $1 150/t and $1 300/t respectively, and petalite prices of $400/t.

Capital Expenditure
The project has a total capital cost of $69.3-million in the 2021 scoping study, compared with $64-million in the 2017 scoping study. The project will require peak funding of $42-million in the 2021 scoping study, compared with $38-million in the 2017 scoping study.

Planned Start/End Date
Not stated.

Latest Developments
Premier African Minerals has reported new intersections of lithium at the Zulu project.

Recent drilling activity on the southern part of the project area returned intersections, including 21 m grading 1.23% lithium oxide and 920 parts per million (ppm) rubidium from 37.1 m; and 20.7 m grading 1.44% lithium oxide and 4 138 ppm rubidium from 21.6 m.

These intersections support the company’s expectations of further discoveries on the project and a likely increase in the mineral resource.

Premier is focused on securing an investment partner for the project.
