Ore in large veins averages 2 to 3 per cent cassiterite. Cost of mining and deliver- 

 ing ore to dressing works is 3s. 2i^d. or 80 cents per ton of 2240 pounds. Cost of 

 dressing is Is. l%d., or say 27 cents per ton, about 6000 long tons of material being 

 treated per month. First grade concentrates average 70.5 per cent tin. Second grade 

 concentrates average 65 per cent tin; does not pay to dress cleaner than this.
