Regarding the Inventories, it's not 'real' value, it's only cost price. See below from annual report.

InventoriesInventories are stated at the lower of cost and net realisable value on a 'first in first out' basis. Cost comprises directmaterials and delivery costs, direct labour, import duties and other taxes, an appropriate proportion of variable and fixedoverhead expenditure based on normal operating capacity, and, where applicable, transfers from cash flow hedgingreserves in equity. Costs of purchased inventory are determined after deducting rebates and discounts received orreceivable.
Cost is determined on the following basis:
● gold on hand is valued on an average total production cost method;
● ore stockpiles are valued at the average cost of mining and stockpiling the ore, including haulage; and
● a proportion of related depreciation and amortisation charge is included in the cost of inventory.

So $140m inventory as at June 2019 would be worth considerably more right now (and would have increased due to production as well)
