The Vigra Gold Mines, North Wales: the Crushing Mill, 1862. Creator: Unknown
The Vigra Gold Mines, North Wales: the Crushing Mill, 1862. The Vigra gold mines are situated in a most picturesque and mountainous range in the parish of Llanabar, on the north of the navigable River Mowddach...in the county of Merioneth. The geological features of this district are the Cambrian rocks, overlaid by the lower Silurian lingula flags. These rocks are coarse, greenish- grey grits. The lingula flags are chiefly slatey beds, more or less arenaceous, and interstratified with courses of sandstone. Both the Cambrians and Silurians are frequently penetrated by light grey calcareous and ordinary greenstone dykes, some of which are magnetic. In the Cambrian sandstone these dykes appear to run in all directions, the general direction being rather across the strike. In the silurian region the direction of the dykes is generally parallel with the lines of bedding. The Vigra mine is situated entirely in the lingula flags...the...water-wheel, which is about 60ft. in diameter, works a powerful Cornish crushing-machine capable of crushing forty tons of ore daily. The wheel is supplied with water from the charming little river called the Hirgwm. At the present time this mine is yielding upwards of fifteen pounds weight of gold per week'. From "Illustrated London News", 1862

EDITORS COMMENTS
This photograph, taken in 1862, showcases the Crushing Mill at the Vigra Gold Mines in North Wales. The mines are nestled in the picturesque and mountainous range of Llanabar, within the county of Merioneth, along the navigable River Mowddach. The geological makeup of the area is characterized by the Cambrian and Silurian rocks, with the former being coarse, greenish-grey grits, and the latter, chiefly slatey beds interspersed with sandstone. The presence of calcareous and ordinary greenstone dykes, some of which are magnetic, adds to the complex geological features of the region. The Vigra mine is uniquely situated within the lingula flags, a part of the Silurian region. The water-powered mill, which measures approximately 60ft. in diameter, operates a robust Cornish crushing-machine, capable of processing forty tons of ore daily. The water-wheel derives its water from the enchanting little river called the Hirgwm. At the time this photograph was taken, the Vigra mine was producing over fifteen pounds of gold per week. The intricate process of extracting gold from the ore was a significant achievement during the 19th century, making this site an essential part of the region's rich mining history.
