REFRACTORY CONCENTRATES: MARKET UPDATE

Chinese demand is still very strong due to:

Unprecedented tightness of the copper concentrates market (globally)

Anticipation of arsenic restrictions in imported materials (locally)

Though, it is very likely that strict and explicit As restrictions will be introduced within 3 years significantly restraining the demand from Chinese smelters

The Russian government intends to curb export of gold refractory concentrates (among other materials containing precious metals) to support local production and refineries POLYMETAL INTERNATIONAL PLC ANALYST AND INVESTOR DAY 32
