Lake Resources moves Kachi into FEED after securing key environmental approval

Kachi moves into detailed engineering

Lake Resources NL (ASX:LKE) has cleared the most significant regulatory hurdle in its September quarter, receiving the Environmental Impact Declaration for its Kachi lithium brine project in Argentina’s Catamarca province. The approval moves Kachi into front-end engineering and design, or FEED, where Lake says it will refine execution schedules and determine final capital costs with engineering partners.

The milestone builds on the Kachi environmental approval, which had previously been identified as a prerequisite for FEED, financing work and a final investment decision. Lake said evaluation of potential FEED contractors was continuing, while discussions with potential strategic partners and global offtakers remained active across India, Korea, Japan, Europe and the United States.

A$7.9 million ATM raise supports cash position

Lake ended the quarter with A$10.129 million in cash, up from A$6.668 million three months earlier. The improvement was driven principally by A$7.9 million raised through the company’s at-the-market facility, via the issue of 157.5 million shares. The financing came after earlier Kachi-related ATM raisings, including a A$3 million ATM raise in September.

Cash use remained concentrated in project and corporate work. Operating activities consumed A$3.212 million, while exploration and evaluation payments classified as investing activities totalled A$1.094 million. Lake said the latter spending primarily covered finalising the environmental approval, evaluating alternative power solutions and transitioning into FEED; it reported no substantive mining production or development activity during the quarter.

Funding runway includes conditional equity capacity

Total relevant quarterly outgoings were A$4.306 million, producing an estimated 6.74 quarters of funding when the company’s cash balance and A$18.89 million of unused financing facilities are combined. That figure is not equivalent to cash in the bank: the unused amount is linked to Lake’s controlled placement agreement with Acuity Capital and depends on market conditions, the prevailing share price and available placement capacity.

Lake said approximately A$3.6 million of the standby equity capacity was available against shares held as collateral by Acuity, with a further A$15.3 million available without shareholder approval at the quarter-end share price of A$0.041. The company is not required to use the facility and said there was no guarantee that a utilisation could be executed.

Power choice and capital cost remain key tests

Lake is still weighing grid-based power options for Kachi, including a northern connection associated with YPF Luz and alternatives linked to the Alumbrera corridor. Solar and battery storage are also being assessed, either independently or alongside grid supply. The company expects to submit its application for Argentina’s RIGI investment incentive regime soon, but the filing does not provide a final power selection, FEED cost estimate or construction financing package.

The balance sheet is therefore stronger than it was at June, but the next phase is more demanding than simply securing a permit. FEED must translate the approved project into a costed execution plan, while partner, offtake and financing discussions will determine how much of Kachi can be advanced without further equity issuance. The next useful marker will be whether Lake can convert its regulatory progress into firm engineering and funding commitments.
