Some of Anglo Asian Mining's (LON:AAZ) operating costs and overheads will be positively impacted by Azerbaijan's currency exchange changes, the miner said today, sending shares higher.
The government announced a switch from a fixed to a floating exchange rate regime for the Azerbaijan New Manat, the firm said.
Against the US dollar today therefore, it amounts to AZN1.55 compared to AZN1.05 previously - an effective devaluation of around 48%.
Anglo Asian said a "substantial portion" of its operating costs and overheads were denominated in Azerbaijan New Manats while its revenues are all in US dollars.
"This move to floating rates and the associated devaluation, whilst unwelcome for the people of Azerbaijan, will therefore have a beneficial impact on some operating costs and some overheads of the company," it said in a stock exchange statement.
The firm is currently evaluating the effect of the effective devaluation on its budget and plans and will update as appropriate.
Anglo is a gold, silver and copper miner in Central Asia.
Anglo shares added 14.71% to 4.875p on the day.
