Primarily a wolframite (tungsten) mine. Situated along the cliff edge at Cligga Head, positioned just northeast of the greisen-sheet vein stockworks. Workings are extensive, with large stopes and substantial equipment left in situ.

Adjacent to these workings, at the same level, is a substantial dump filled with arsenopyrite, wolframite, iron, and copper minerals. However, it’s important to note that some of these dumps may originate from the Perran Great St George and Good Fortune mines, which also have workings further inland, west, and north of the airfield currently utilized by a glider club.

• Pre-1825 - Ancient cliff workings extracting tin, with tungsten present as a gangue mineral.
• c.1825–late 19th century – Operated as Wheal Prudence, a nineteenth-century open tin mine.
• 1938–1939 – Cligga Wolfram and Tin Mines Ltd established; mine equipped and rich tin–tungsten veins exploited.
• 1939–1945 – Taken over by Rhodesian Mines Trust Limited; Contact Shaft deepened to near sea level and new stopes driven. Mine closed in 1945.
• Early 1960s–1964 – Geevor Mining Company attempted shaft rehabilitation and deepening to reopen the mine; work ceased in 1964.
• 1976 – Further unsuccessful attempt to restart mining.
• 1984–1985 – Final recorded prospecting attempts; project abandoned.

Access to the mine itself is possible through the cliff portals at each of the three levels (top, middle, and bottom). The bottom level is accessible from the beach at the cliff foot (tide permitting). Access is also possible through a shaft at the surface. It is possible to navigate between levels internally. Top-to-middle level requires ropework, but middle-to-bottom level can be navigated without equipment.

Cligga is a popular location due to the relatively easy access and nearby parking, so the internal damage is considerable. Please treat this location with respect, and don’t add to the spray paint, litter, or mineral hunting devastation.
