Nantyricket, CPAT photo                Copper (Prehistoric ?/19th century)

Ordovician grits and conglomerates of the Lower Van Formation with chalcopyrite and calcite veins striking ENE.

An adit at the rivers edge on the north side of the Severn, probably 19th century in date. SN86708676. A deep narrow opencut on the south side associated with a small processing area and spoil tip close to the rivers edge. SN86658676. A wide opencut north of the present forestry track at SN87158678. O.T. Jones recorded a deep narrow opencut 200yds east of the main adit known as the 'Thieves Den' where a number of hammerstones are recorded on the spoil tips along with charcoal and burnt stone, presumably from firesetting. This site has not been located.

An inclined trackway connects the adit to the present forest road above.

No evidence.

There is some evidence of hand sorting and limited dressing close to the narrow opencut on the south side of the stream.

Other features
A rectangular building of unknown use is located downstream of the narrow opencut on the south side of the Severn SN86698678. Two internal divisions are visible and it appears to be drystone walled. This structure may be related to farming activity or it may be a small mine office related to 19th century workings mentioned above.
