This is the point at which the copper lode is thrown about 700 feet to the south due to 'the Great Crosscourse'. Unfortunately unlike nearly every other crosscourse in this area there was no lead/silver mineralisation. There is an extensive dump of crushed killas alongside the stream which flows due west from the arsenic chimney and one shaft head (it has to be eastern or Western shafts which were practically side by side) is also visible.
The dump is mostly barren except for poor, degraded Arsenopyrite and a little pyrite.

In 'The Mines of East Cornwall and West Devon' D.B. Barton cites one section on the lode as having 'been excavated for 900 feet in length, 140 feet high and 6 to 50 feet wide'. This may well be a reference to the Wh Fanny section which by a rough paced estimate of the currently accessible underground works must have these approximate dimensions.
