PanTerra Gold (ASX: PGI) expects plant throughput at its Las Lagunas Gold Tailings Project in the Dominican Republic to reach design feed levels soon after completing the upgrade of the ultrafine grinding mill.
The new mill is expected to allow design throughput of 2200 tonne per day at the 12 micron grind size required to optimise oxidation of the refractory ore, and subsequent metal recovery.
Replacement of the smaller 3m3 shell of the ultrafine grinding mill to a larger 5.0m3 mill took 48 hours.
Forecasts for 2013 will be published after three to four weeks of stabilised production following the mill upgrade, and are expected to be robust, with the project operating to design throughput and recoveries.
The first gold silver doré was poured by PanTerra at the project in July this year.
Las Lagunas is being undertaken on a profit sharing basis with the Dominican Republic
Government which does not cut in until the company has recovered construction costs.
Previous issues with the oxidation circuit treating refractory ore have been resolved with PanTerra saying last week that sulphide oxidation and other processing performance indicators are nearing design target.
