Overview
A small lead and copper mine in Swinburn Gill, part of the Caldbeck Fells' Roughton Gill group, whose carbonate-poor ore produced an exceptional suite of oxidised minerals -- including the type specimens of redgillite -- collected long after mining itself had ended.
History
Red Gill Mine worked an approximately WNW-ESE trending quartz-baryte-chalcopyrite-galena vein in Swinburn Gill, a minor tributary of the Dale Beck valley in the northern part of the Caldbeck Fells, in the Caldbeck Fells, a lead-copper-baryte mining district in the northern Lake District worked from the arrival of German miners around 1564 through to the closure of the last barytes workings in 1966 -- a mining history spanning over 400 years. Worked mainly on the west side of the gill, the mine's ore was worked chiefly for lead and copper. Because the vein's gangue is unusually deficient in carbonate minerals, the oxidation of its ore produced a remarkable suite of rare secondary minerals rather than the more ordinary carbonate weathering products typical elsewhere -- among them fine specimens of caledonite, leadhillite and, especially, linarite, collectable well into recent times, and the type specimens of redgillite, a mineral first described from this locality and named for it.
Geology
A quartz-baryte-chalcopyrite-galena vein trending roughly west-north-west to east-south-east in Swinburn Gill, part of the Roughton Gill group in the Caldbeck Fells. The ore was carbonate-poor.
Workings
Worked a WNW-ESE quartz-baryte-chalcopyrite-galena vein, mainly on the west side of Swinburn Gill.
Closure
Unknown.

Recorded claims
Individual factual claims, each attached to the source(s) that support it below. Where sources disagree, both are kept.
- Red Gill worked a WNW-ESE trending quartz-baryte-chalcopyrite-galena vein in Swinburn Gill; the vein's gangue is unusually deficient in carbonate minerals, which caused its ore's oxidation to produce a remarkable suite of rare secondary minerals rather than ordinary carbonate weathering products. 1
- Red Gill is the type locality for redgillite, a mineral first described from and named for this site, alongside fine specimens of caledonite, leadhillite and linarite. 1
- Red Gill sits within the Caldbeck Fells mining district, worked from the arrival of German miners around 1564 through to the closure of the last barytes workings in 1966 -- a mining history spanning over 400 years. 2
- The Red Gill Mining Company leased the site in 1861, extending the workings and opening nearby prospects, but raised only 28 tons of lead ore and 45 tons of copper ore before going bankrupt in 1871; there has been no commercial working since. 3
