Hi Salt,
The previous BOD reported 13 kg gold (458 ounces) processed prior to the shutdown in October 2016. The only other report I recall is the 380 ounces given to Cartesian in January 2018.... as you can see this is well below your estimate of 2000 ounces based on 30,000 tonnes of tailings (at 2 grams per tonne)... not sure where the other recovered gold went...hmmm.
