114 PEECIOITS METALS IN THE WEST OF ENGLAND. 



£5,847 12s. 8cl. worth of silver ore was raised and sold; shares 

 rose from £5 to £1,000, £1,600, even £2,200 each; considerable 

 quantities of silver were raised during the next four months, and 

 £9,000 was paid in dividends. Then followed a call, to the 

 disgust of the shareholders, and the mine was soon abandoned. ^^ 



In 1813 a discovery of native silver associated with red-grey 

 and black ores, together with the carbonates of copper, was met 

 with at Wheal Alfred near Hayle. The same year some silver 

 ore was got from a cross-course at Wheal Basset, at the 28 fm. 

 level below adit (38 fm. from surface). Some of the grey ore 

 yielded 600-ozs. to the ton : it is worthy of notice that the galena 

 associated with this ore was not itself rich in silver.*^ 



In 1814 a small bunch of blackish-grey silver ore, together 

 with native silver, arsenical pyrites and spathose iron ore, was 

 found in an E.W. copper lode at the 65 and 75 fm. levels at 

 Wheal Ann, in Phillack. 



The Willsworthy copper mine, although actually in Cornwall, 

 is in the near neighbourhood of the Tamar lead mines. The Devon 

 lode here is in general about one foot wide, it courses N.N.E. and 

 underlies to the S.E. about 2i-it. in a fm. In the year 1815, in 

 the 10-fm. level, a vein of white and amethystine quartz divided 

 the lode, between this and the foot-wall was a vein of rich 

 arsenical cobalt ore with native capillary silver in a ferruginous 

 matrix, from 3 to 6-ins. wide. From the quartz to the hanging 

 wall was a vein of rich yellow coj)per ore 6 to 9 -ins. The silver 

 continued for two fathoms, the copper farther.^^ 



Wheal St. Yincent, near Calstock, yielded considerable 

 quantities of many varieties of silver ore from a lode which ran 

 parallel to and south of that of Wheal Duchy, and about the 

 same time. This mine was closed in 1824, and re-opened in 1835 

 as the East Cornwall Silver mine. It was then worked for about 

 two years and yielded 1 ton, 8 cwt., and 14 lbs. of silver ore, 

 containing about one thousand ounces to the ton., It was again 

 worked as Wheal Langford in 1855, and sold in June of that
