Well looks like it wasn't lining on site just more dirt being shifted around - this new pond is going to be a whopper!
Evaporation for August was 117 mm http://rinconmining.com.ar/rinconpi/mb5lr.htm
Can only assume it would have been the same or greater for September. Considering the ponds are filled to 400mm, I don't see why there wouldn't be several re-fills .... the process involves the brine to be 'concentrated' not dried.
Still on track for new pond to be filled during November I reckon.
