Answering own question. Half share my be around 270,000 ounces at AISC of US$1,204 or AUD$1,770 according to Kalkine Media report:

“Barrick Gold has posted strong numbers for the Kalgoorlie superpit for the year 2019, as per the company the production from Kalgoorlie attributable to Barrack Gold should remain in the range of 260,000-280,000 ounces in 2019, with a cash cost of US$740 to US$790 and all-in sustaining cost of US$1,010 to US$1,050 per ounce.

During the June 2019 quarter, the production from Kalgoorlie superpit remained at 57,000 ounces, which in turn, underpinned the growth of 4 per cent as compared to the previous corresponding quarter production of 55,000 ounces. The total cash cost from the Kalgoorlie marked a decline of 3 per cent, and the total cash cost stood at US$864 per ounce in the June 2019 quarter, as compared to the total cash cost of US$870 per ounce in the previous corresponding quarter.

However, the all-in sustaining cost (or AISC) witnessed a slight increase of 2 per cent, and the AISC for the June 2019 quarter stood at US$1,204 as compared to US$1,185 per ounce in the previous corresponding quarter. In 2018, the operations produced 314,000 ounces of gold with an AISC of US$857 per ounce.

The estimated Proven and Probable Reserve of the prospect stands at 3.65 million ounces, while the Measured and Indicated Resources stand at 1.5 million ounces.”

Let’s see what’s in the release but hope expectations are better than above estimates.
