be accurate 300-400kt of zinc on stock piles? Latest number I saw was still approx 260kt which is nothing in the scheme of 13.5mtpa market.

LME gone up 25kt to 75kt?
SHFE has increased around 20kt a week for the last month and I’m sure you can attribute that to logistical issues in China due to CV. Not just your hidden stocks argument.

As for surplus read the latest ILZSG report. Clearly shows a deficit of around 180kt for 2019. Funnily it’s forecast for surplus this year but let’s see. The predictions haven’t been right so far.

As for your prediction on NCZ unfortunately I would suspect that century tailings will continue to stay. Going to 12mtpa drops it’s cash costs well below a lot of other mines out there including the likes of other big producers like Trevali the Chinese etc. not many mines have the chance to increase production by 40% with relatively minimal increase in costs.
