Ann: Orocobre Limited - September 2018 Quarterly Report, page-8

On the positive side:

Production, Sales, price received and COGS are all improved on same time last year.
Share price at posting 3.33. Share price last year was around $5 climbing up to $7%.

This is also on the back of 2 weeks shutdown and "lower evaporation rates." 

So realistically we should be at about 30% above last year with better contract prices and lower COGs. And still with more growth to come.

On the negative side:

from some rough calculations 2 weeks of no production does not make up for a 36% drop.

If we use 13 weeks for a quarter with last quarter production at 3,600~. That give us 276 tonnes per week.
So if we didn't have the 2 week shutdown we would still only be at 2,850~ tonnes which is still about 20% lower.

Maybe there is a slow down before the 2 weeks and then a ramp up after the 2 weeks. I hope that poor evaporation does not account for 20% of production.
