Disturbed dumps by coast path from Porthleven to Loe Bar. Adit in cliffs below.

Russell and Hutchinson (1927): "Wheal Rose and the adjoining mines Wheal Penrose and Wheal Pool are probably the oldest lead mines in Cornwall, records of their working dating back to 1625. The main lode at Wheal Rose has a direction nearly due north and south magnetic, and outcrops on the low cliff three-quarters of a mile south-east of Porthleven (6-inch ordnance map, 76 SW.). The mine was worked to a depth of 54 fathoms, the southern levels extending under the sea and the mine water being extremely salt. The upper portion of the lode consists of limonite and comby crystallized quartz with galena, and a little chalcopyrite and blende. In depth the limonite changed to chalybite (= siderite) and this during the last working, about 1864, was mined as an iron ore. The galena contained 60 ounces of silver to the ton."

Laurionite
Formula: PbCl(OH)
Habit: bladed.
Colour: colourless
Description: Russell and Hutchinson (1927): "The crystals of laurionite are colourless and translucent and bladed in form, attaining a length of 4 mm.[...] The following forms are present: b(010), m(ll0), n(120), d(012), and the prominent but somewhat doubtful form p(141). [...] The faces as a whole appeared to be etched and afford multiple images, with the exception of m(110) which gives good reflections. As in the case of the Laurion crystals the faces of b(010) are striated parallel to their intersection with the pyramid p(141), the latter being possibly a vicinal form as suggested by Dr. Herbert Smith. The edges formed by the intersection of the faces p(141) are always more or less curved, thus giving rise to the bladed form. No interference-figure can be seen looking through (010). The crystals when powdered are partially soluble in boiling water. The presence of lead and chlorine was determined. Of the three associated minerals, laurionite, phosgenite, and anglesite, the laurionite appears to have been the last formed, and partially invests the other two."

'Limonite'
Formula: (Fe,O,OH,H2O)
Habit: mamillary; lenticular (pseudomorphous after siderite)
Colour: velvety black; brown
Reference: Collins, J.H. (1892) A Handbook to the Mineralogy of Cornwall and Devon, 2nd ed., D. Bradford Barton Ltd. (Truro, UK), pp. 108.; Russell, A. and Hutchinson, A. (1927) On laurionite and associated minerals from Cornwall. Mineralogical Magazine, vol. 21, n° 116, 221-228.
Mimetite
Formula: Pb5(AsO4)3Cl
Reference: Hill, J.B., MacAlister, D.A., and Flett, J.S. (1906) The geology of Falmouth and Truro and of the mining district of Camborne and Redruth. HSMO Publications (London), 335 pp.
Paralaurionite
Formula: PbCl(OH)
Habit: The crystals are long narrow thin plates without for the most part any terminal faces and when measured gave angles consistent with the supposition that they are crystals of paralaurionite elongated along the symmetry-axis and twinned about a(100) with the faces of a large and those of c(001)small. [...] There is an excellent cleavage parallel to c(001). Indications of other faces in the zone a c were observed, and it is probable that h(201) is present on some crystals as a very narrow face. The important face m(ll0) mentioned by Herbert Smith was not observed, but a face making an angle of 24°24' with a was found instead. Simple indices cannot be assigned to this face ((510) would correspond to an angle from a of 25°38') and it is probable that it is an accidental face produced where one crystal has come in contact with another.[...]
