Molybdenum Market Million pounds Mo 2014 Non Chinese Mo Production 380 Up 8% from 2013 China Net Trade 22 Up 24% from 2013 Supply Ex-China 402 up 32m lbs or 8.7% from 2013 Metals Week YTD July Price $11.99 $9.52 in ‘13, a 26% increase to ‘14 MW Price as of Aug 13 $13.05 $9.25 in ’13, a 41% increase to ‘14  Market is very tight during seasonally slow period  At the start of 2015 Thompson Creek Mine will reduce annual supply by 18 million lbs  With the current low inventory levels the Sierra Gorda start-up is not weighing on the market  High levels of production (40m+ lbs) from Sierra Gorda likely will be price disruptive  The key to market pricing will be the China primary production response to low cost supply expansion
