An old tin mine lying to the south of the River Lynher, also known variously as Wheal Flop and Wheal Annie.
It is recorded that the granite at this locality is traversed by a number of greisenised joints. Some of these joints show quartz infill with variable quantities of cassiterite, wolframite and 'mispickel' - whether this is arsenopyrite or löllingite is not specified.
Three of these veins were sufficiently mineralised to be known as North Lode, Flop Lode and South Lode.
The early output of the mine appears to be somewhat incomplete.
The mine was re-worked in the first world war but only yielded 55 hundredweight of wolfram concentrate. Further working took place during the second world war yielding 2000 tons of ore, of this figure some 1600 tons was selected and processed at the Prince of Wales mill.
These workings should not be confused with the Treburland Manganese Deposits which lie to the east of this mine.
1 valid mineral.
