The CME is a paper market for Zn. It affects CSD through pricing the underlying commodity, Zn. Therefore it is material to CSD in as much it affects the daily sp partially based on CSD's assets, cost of production (thanks E1 for costing clarification) of Zn.
CSD would not be a good proxy for Zn in this context because it is a polymetallic producer, eg. some metals go up -- anyone notice Ag's move? -- and some metals go down. A pure or almost pure Zn producer would be the best proxy for Zn outside the LME, CME, and easiest to play for retail folks.
