Russell (1946):
"This, the most important of the three workings, lies at an elevation of about 1100 feet above sea-level, 430 yards north of the west end of Loch na Mèine, on the high ground about midway between Strath Glass and Strath Farrar, and is reached by a rough track leading up from Struy.
Here is to be seen a hush running west down the hill, the site of two filled- in shafts which are connected by a shallow adit-level, and the remains of a water-wheel for pumping, water to work which was brought by a leat from Loch na Mèine (Loch na Mèine is in part if not wholly artificial as its eastern end is formed by a dam); also reservoirs, a dressing floor on which there still remains some broken ore, and a curiously designed and apparently unfinished smelter chimney, wrongly described in the Geological Survey Memoir as the ruins of an engine house.
Of the three this was the only mine which seems to have produced any marketable ore, but from the small size of the dumps, corroborated by the section, very little actual stoping appears to have been done.
The engine shaft was sunk to a depth of about 18 fathoms, the other or older shaft on the incline of the vein to 14 fathoms.
Besides the adit, a level from the engine shaft communicates with the bottom of the older shaft, and from the engine shaft, another level at a depth of 11 fathoms has been driven east a few fathoms.
There are two chutes of ore shown on the section, the principal in the older shaft, and another at adit-level in the engine shaft.
The total length of the workings is only 20 fathoms.
The vein here cannot actually be seen but has an approximately east and west direction with a dip to the south of about 33° from the vertical.
The vein-filling consists largely of pink and white baryte and quartz with embedded masses and coarse cleavage cubes of galena, and small quantities of black blende; also included masses of quartz-muscovite-granulite.
The galena is said from assays to have yielded from 7 ounces to 22 ounces 11 pennyweights of silver to the ton of ore."

Alphabetical List Tree DiagramDetailed Mineral List:
ⓘ Anglesite Formula: PbSO4 Habit: The anglesite crystals, two of which were measured, are elongated in the direction of the c-axis and show the forms a (100), λ (210), h (340), o (011), and y (122). The faces (100), (210), and (340) are deeply fluted vertically from repetition. Colour: colourless to greyish Description: A single specimen only was found at the Loch na Mèine working. It shows minute, up to 2 mm., colourless to greyish bladed crystals occupying a cavity in galena and baryte, with a little quartz, cerussite, and a coating of pyromorphite on which are minute crystals of wulfenite. |
ⓘ Baryte Formula: BaSO4 Habit: coarsely lamellar; elongated in the direction of the b-axis and showing the forms (100), (110),
(102), (011), the two latter largely developed, (021), (111), (122), also narrow faces of (166) between (011) and (122). Colour: pink; white; colourless Description: small transparent crystals not exceeding 8mm. |
ⓘ Cerussite Formula: PbCO3 Habit: Small patches and small, up to 5 mm., colourless crystals of varied habit in pyromorphite-lined cavities. These crystals are prismatic in the direction of the c-axis and either simple or twinned on m (110); they show the forms b (010), c (001), m (110), x (012), k (011), i (021), p (111); others are pyramidal in habit and twinned on m (110). Axial ratios and letters for this and the other minerals here described as in Dana's System of mineralogy, 6th edition, 1892. |
ⓘ Galena Formula: PbS |
ⓘ Harmotome Formula: Ba2(Si12Al4)O32 · 12H2O |
ⓘ Muscovite Formula: KAl2(AlSi3O10)(OH)2 |
ⓘ Pyromorphite Formula: Pb5(PO4)3Cl Habit: crusts of minute grass-green stout hexagonal prisms; also siskin-green slender tapering prisms investing pyramidal crystals of quartz, and more rarely minute golden-yellow transparent prisms associated with cerussite and wulfenite. Colour: grass-green; siskin-green; golden-yellow |
ⓘ Quartz Formula: SiO2 |
ⓘ Sphalerite Formula: ZnS Colour: black |
ⓘ Wulfenite Formula: Pb(MoO4) Habit: Acute pyramidal. The crystals are sharp and well-defined and consist of the acute pyramid (111) either alone, or usually in combination with (221), the prism (110), and base (001). The faces (111) are slightly curved except at the apex and merge by repetition into those of (221) and (110), giving the whole crystal a curved outline, some, in fact, being almost barrel-shaped. The basal plane (001) is never smooth, the surface being either square-pitted or studded with innumerable extremely minute (111) pyramids. The faces of (110) are horizontally striated from repetition with the adjoining pyramids, while on most of the crystals the surfaces of (110), (221), and (111) are covered with raised and overlapping outlines of acute pyramids giving them a scaly appearance. In some crystals, two parallel pyramids (111) terminate a single prism (110). The measurements obtained from each of the faces are poor, but good enough to identify the forms with certainty. Colour: Orange-red, rarely golden-yellow with blotches of red. Description: Very small, not exceeding 2 mm. The crystals either project from, or lie flat on, thin crusts of minutely crystallized green pyromorphite, which invests baryte, small bipyramidal crystals of quartz, or hacked quartz from which baryte has been leached. On other specimens single crystals of wulfenite project from cavities in massive baryte lined with ochre. Sometimes as many as 25 minute crystals are present on a square inch of the pyromorphite-covered surface. The wulfenite appears to have been the last mineral formed. In a few cases, wulfenite crystals are penetrated by and have grown round prisms of pyromorphite. |
