Ann: 5N HPA Production Confirmed, page-18

This from A4N(I am no longer a Holder) today;
A consolidated summary of pricing for products to be manufactured within Stage 2 is presented below:
Product Pricing (US$/kg)
Alpha HPA Market Discovery Independent Consultants Product Low/High Demand Vol Weighted Avg Equivalent:

5N Purity Aluminium Nitrate 15.0 350.0 18.5 123.3 n/a 20 - 30 125.0
4N5+ Purity Alumina 20.0 68.5 32.0 32.0 39.3 n/a 39.3
4N5+ Purity Alumina for pucks 20.0 30.0 25.0 25.0 35.0 n/a 35.0
4N5+ Purity Gamma Alumina 13.0 30.0 20.3 20.3 27.5 n/a 27.5
4N5+ Purity Alumina Trihydrate 12.5 20.0 15.0 23.1 19.4 n/a 29.8
4N5+ Purity Nano-Alumina 33.0 44.0 43.0 43.0 50.0 n/a 50.0

*Demand Vol Weighted Average: Average prices weighed by volumes indicated from customers and potential end-users,
and/or sales achieved.
** HPA Eq: Is calculated from Demand Vol Weighed Average*. Al-Nitrates and alumina tri-hydrate have lower aluminium
content than high purity aluminas but a close to equivalent sales value by unit weight, provides a lift in HPA/Eq price received
versus the HPA product price.

If you find that a little hard to understand? Just go to their announcement today. Basically it's stating that demand for 4N is 7 times greater than 5N.
