In addition to better grades at Wiluna OP, the proximity to the plant is a real cost saver compared to Matilda. What will also be interesting is the stripping ratio. 1:1 (or less) is fantastic, 3:1 is pretty good & 7:1 can work if ore grade, haulage & mill throughput are good enough. Hopefully the stripping ratio at Wiluna OP will be consistently better than Matilda.
