Barton Gold — Firing on all cylinders

As promised, on 5 May, Barton announced the results of its optimised scoping study on its Tunkillia project in South Australia. Relative to its initial scoping study (July 2024), capex was down 8.0%, while unit oxide and sulphide processing costs were 24.4% and 18.0% lower, respectively, as more realistic ore hardnesses were considered for grinding purposes. The life of the operation has been extended from 7.7 to 10 years, with the result that the amount of payable gold produced has increased by 13.1%. In conjunction with a 42.9% increase in the gold price to A$5,000/oz (c US$3,333/oz), these changes (among others) resulted in an increase in pre-tax project NPV7.5 of 176.6% to A$1,416m and an 33.2 percentage point increase in the internal rate of return to 73.2% (A$781m and 48.3% at A$4,000/oz Au, respectively). Using the same inputs, our financial model generates an NPV7.5 within 6% of Barton’s, from which we estimate a post-tax project NPV7.5 of A$895.9m, or A$4.09/share.
