    St Dizier is a satellite open-pit tin deposit located 20km to the northwest of Zeehan. St Dizier is a tin skarn, formed by metasomatic alteration of an original dolomite unit by tin bearing fluids emanating from the Heemskirk Granite. Much of the dolomite is altered to serpentine-magnetite-calc-silicate rock flanked by shales to the south and
