			== 10/05/2026: Release: Arsenic Labyrinth & Live at Stones Drones & Noise ==

			Limited Edition Cassette & MP3 [https://cornish-semiconductor.bandcamp.com/album/arsenic-labyrinth release on bandcamp]

			[[File:Title2.jpg\|500px\|right]]

			[[File:Tapes.jpg\|500px\|right]]

			Side A: arsenic labyrinth: arsenopyrite semiconductor square waves resonant filtered using chalcocite crystals, both fossicked from mine waste dumps at Wheal Prosper, St Hilary, Cornwall. Sequencing, modulation and rhythm sounds using a pair of second hand volca modulars. Circuits adapted for natural semiconductor use from Roland TB-303 style ladder design.

			Wheal Prosper was originally part of Marazion Mines, and later (after 1860) Prosper United. From 1832-49 14,600 tons of copper ore were sold, worth £60,000. Minor sales of tin, arsenic and lead ore are also reported. Today (2026) the site is accessible via a public footpath and consists of many overgrown dumps, crisscrossed by tracks with one large area of exposed mine waste. Melanterite is abundant here, and blows about in the wind when you disturb the surface rock.

			Side B: live at Stones Drones and Noise Club at Gwithti an Pystri, Falmouth, 28th Febuary 2026. During the performance the following Cornish semiconducting minerals were switched between: Square wave voice: ◇ chalcopyrite and galena from Ale & Cakes Mine, Gwennap, ◇ chalcocite from Penstruthal mine, Lanner, ◇ cassiterite from Unity Wood Mine, Gwennap. Triangle wave voice ◇ chalcocite from Penstruthal mine, Lanner, ◇ arsenopyrite from Penlee beach, Newlyn. Noise voice: ◇ pyrite from Nangiles Mine. Distortion (see circuit diagram) on 4 track ambience: paired chalcopyrite crystals from Ale & Cakes Mine. Includes field recording fragments from Wheal Busy, Chacewater.

			Thank you to Jessica Beechey and Steve Patterson for giving the world stones drones and noise, and recording and kindly providing the cassette of this performance.

			The circuit board on front cover is the experimental natural semiconductor diode ladder filter used extensively on side a of the recording.

			Recorded in Cornwall in 2026 by Dave Griffiths
