Caption: Wolfram Mine, Castle an Dinas, Cornwall.
Description: Looking north at Castle an Dinas Wolfram Mine. The photograph shows the Old Shaft and mill on the northern slopes of Castle an Dinas hill. The structure in the foreground is the tension member for the overhead ropeway from New Shaft. The ore bin for ore raised from Old Shaft is just beyond the headgear. Ore from New Shaft is delivered into the bin above the processing mill. The wolfram lode had been productive for a length of nearly 1,800 feet. A few exceptionally rich patches were found in the higher levels and an average value of 30 per cent wolfram persisted at deeper levels. 46.5 tons were produced in 1918, a recovery of 28.76 lbs per ton of ore.
