Lincoln Minerals' Kookaburra Gully Project - Graphite

The Kookaburra Gully Graphite Project is one of the highest-grade graphite projects globally. It has a very low start-up capital cost of A$44M and a production profile suited to world graphite demand and supply volumes.
The project has an Ore Reserve and completed Feasibility Study based on a processing rate of 250,000 tpa to produce 35,000 tpa graphite flake concentrates on-site over a 10-year open pit mine life.
The Kookaburra Gully Project has significant opportunities for further value enhancement including;
• Extension of project life beyond 8-10 years,
• Incorporating further value-adding product development including spherical graphite manufacture for the battery market, and
• Potential savings on implementation costs due to conservative design and costings adopted.

Project highlights

  • The project has a very low A$44M start-up capex and a low cost per tonne of graphite concentrate produced on a global basis. As per November 2017 published Feasibility Study (on-site production of graphite concentrates): • Pre-tax NPV10% of $81M over the life-of-mine (10 years) • Internal rate of return of 33% • Payback period of 3 to 4 years • Operating cost of A$705 (US$550) per tonne concentrate for LOM
