But it added that the gold produced in June would raise approximately $1.3m, covering the group's operating costs for the month.
Angel said it had completed two gold dor pours before work stopped, bringing the total amount of dor poured in June to 27.46kg (883 oz).
The next gold pour is expected to be in late July and the company expects the quantities of gold produced to resume growing because it will be processing ore from higher grade pillars.

Following the announcement Angel's shares fell 19% but recovered to trade down 15% after almost an hour of trading.
