In 1827, Treskerby and North Downs, near Redruth, yielded 

 small quantities of silver ore which sold for £15 14s. 4d. and 

 £3 4s. 9d. respectively. In 1847-8 a mine on the eastern part 

 of the Wheal Duchy lode, named Wheal Mexico,*^ yielded a good 

 deal of chloride of silver, which was sold at prices varying from 

 £5 to £200 per ton, while some small specimens were sold at 

 £2 10s. Od. per lb. Wheal Jewel, four miles S.E. from 

 Callington, also yielded native silver m capillary form, together 

 with ruby-silver, argentite and lead and copper ores from a vein 

 rarely more than 4-ins. wide.*" 



From 1852 to 1855 West Wheal Darlington yielded ores of 

 silver from an east and west lode composed of quartz and slate 

 with yellow copper ore and iron pyrites. At a depth of 40 

 fathoms from surface and 24 below the sea level the lode yielded 

 chalcopyrite, galena and native silver. During the period named 

 there were sold 309 tons and some odd cwts. of silver ore which 

 realized £3,659 os. Id. A small parcel was sold (seven lbs.) at 

 the rate of £5,120 per ton, some, however, only realized £1 per 

 ton, while the average was £11 16s. 8d. 42 tons 10 cwts. 3 qrs. of 

 ore remained unsold when the accounts were made up and it is 

 not known how much this parcel realized.*^ 



In 1859-62, silver ores were raised at the crossing of two 

 lead lodes by an iron lode at Trebisken Green in Perranzabuloe. 

 In some parts where native silver and vitreous silver were visible 

 the whole mass assayed 10 per cent, for silver. In all nearly 10 

 tons were sold from this place which realized £1,245 17s. 7d. 



In 1861-4 Wheal Ludcott sold 306 tons of silver ore for 

 £22,583 8s. 8d. This was almost all raised from a vein which 

 crossed the main lead lode and from very near the intersection.
