Let me add to that @29101971 , OZL quarterly released 24th October,

“Final binding agreements for the $1.2 billion syndicated debt facility have been signed with a number of our relationship banks to support the development of the West Musgrave Project. Financial close under the syndicated debt facility is expected by the end of October 2022."

Therefore finance/lending is not an issue for OZL's large $1.2B debt. This is a good sign that finance is still viable for CYM.

Add to this CBA forecasts that the USD will strengthen in coming months and the AUD will fall sub US60c.
From a CYM perspective, the copper price drop has been mirrored by a decline in the AUD which you pointed out. From both a profit & free cashflow perspective nothing has changed with regard to CYM's ability to service that debt.

"The ports of Los Angeles and Long Beach together handled 686,133 loaded import containers in September, down 18% from a year earlier and the lowest level since June 2020, according to port figures. August imports fell 12% from last year, a steep drop during the traditional peak shipping season."
Although this refers to US freight movements these downward freight costs are across the board. Freight costs are going down, steel costs are going down, fuel costs are steady with WTI oil at US$84.92/barrel and has been trading around this level since early Sept a long way off its $120+ peak in June.

Steel price is forecast to fall in 2022 and beyond. Fitch Solutions, in its 16 September note, lowered the steel prices forecast for 2022 to $860 per tonne from a previous forecast of $980 in June. It also cut the price estimate for 2023 to $825/tonne from a forecast of $850 in June, as weaker global economic growth put greater downward pressure on prices.
