Cooper & Stanley (1991):

"Almost nothing is known of this mine. It was worked from two short crosscuts (now caved) to an approximately NNW-SSE vein, and the associated dumps suggest, in local terms, a relatively extensive operation. The mine was last opened in the mid-19th century but this was merely a trial operation and nothing came of it. The present dumps are almost barren of specimen-quality minerals, although pyromorphite and cerussite are common in small amounts.
The occurrence here of mattheddleite is only the second locality known for this new species."

Detailed Mineral List:

ⓘAnglesite
Formula:PbSO4
Habit: bladed
Colour: cream to black
ⓘBaryte
Formula:BaSO4
Description: Small (ca. 1 mm) clear and opaque white crystals of baryte occur in cavities in limonite stained quartz and in one case enclosing a supergene copper mineral. Some of the baryte crystals resemble one form of anglesite with which they may be easily confused at first sight.
ⓘ'Bindheimite'
Formula:Pb2Sb2O6O
ⓘBrochantite
Formula:Cu4(SO4)(OH)6
ⓘCalcite
Formula:CaCO3
ⓘCaledonite
Formula:Pb5Cu2(SO4)3(CO3)(OH)6
Description: As small crystals and masses with linarite from the mine dumps and from waste material at the foot of the 'hush' to the north of the lower dump.
ⓘCerussite
Formula:PbCO3
Habit: acicular; granular
Colour: white
Description: Cooper & Stanley (1990): "First mentioned, without description, by Greg & Lettsom (1858: 391) from 'Bray Fell'. Crystals are generally insignificant but an attractive combination of silky, white, acicular crystals (< 10mm) with small green pyromorphite crystals was found on the low-level dump (Kingsbury collection, BM(NH)). Crystals (< 20mm) occur with bright canary yellow pyromorphite on the top level dumps."

Habit: bladed or fibrous aggregates
Colour: colourless to greyish white
Description: Cooper & Stanley (1990): "The record by Young (1987) of lanarkite with leadhillite from Brae Fell in the NMW Collection is an error (R.E. Bevins, pers. comm.)."Green et al. (2008): The first claim of lanarkite in the Caldbeck Fells was made by Arthur Kingsbury, who described three small specimens from Brae Fell Mine in an unpublished manuscript on the minerals of the northern Lake District in 1951: these were examined in detail by Bridges et al. (2006) who consider it unlikely that they are from Brae Fell Mine and therefore that they are fraudulent."

ⓘSusannite ?
Formula:Pb4(CO3)2(SO4)(OH)2
Habit: sheafy, tabular

Description: Kingsbury reference.

A recent examination of this specimen (BM(NH)) showed that these crystals, and a later generation in thin, brown, crystal aggregates, all gave an X-ray powder pattern identical to that of susannite."
