PanTerra Gold announced plans to halt operations at its 200,000-tonne per annum Las Lagunas processing plant in the Dominican Republic, as reported in Stockhead online. The Australian company said it is putting up the gold processing plant for sale after failing to win support from the Dominican government for its future plans. PanTerra had intended to use imported concentrate after the current tailings retreatment project comes to an end in mid-2019.
The Las Lagunas plant uses a sulphide oxidation process developed in Australia to oxidise refractory ores to allow the recovery of precious and base metals using conventional extraction technology.
As reported by PanTerra, the Las Lagunas plant has delivered the company a “disappointing financial performance” largely due to poor gold recovery (63 per cent) from the low-grade (10 grams per tonne) concentrate that can be produced from the refractory tailings. PanTerra was confident that a clean concentrate from mined sulphide ore would have a higher gold grade of over 40 grams with a much better recovery rate of over 90 per cent.
