READ: Core Exploration targets lithium concentrate production at Finniss by late 2019 The company is on the path to low-capex lithium concentrate production by late 2019 at its Finniss Lithium Project near Darwin in the Northern Territory. Core aims to complete regulatory approvals, financing and internal approvals before commencing production at the Grants deposit by the end of 2019. READ: Core Exploration enters lithium offtake term sheet with US$35 million prepayment, share rise A pre-feasibility study (PFS) clearly demonstrates the Finniss project economics to be compelling, with globally competitive cash costs that result in high operating margins and rapid capital payback. Grants is a key component of the project and is expected to generate a net present value (NPV) of $140 million (pre-tax) with an internal rate of return (IRR) of 142% at an average concentrate price of US$649 per tonne. Interestingly, the NPV is anticipated to increase to $246 million if the recent spot concentrate price of US$895 per tonne is realised. Finniss comprises more than 500 square kilometres of tenements across the Bynoe Pegmatite Field, with exploration results confirming that ore-grade lithium mineralisation is widespread. Core's 2018 drilling is aimed at growing the resource to underpin a potential long-life lithium mining and production operation. The company is focused on completing a definitive feasibility study later this year.
