South Hooe Mine, often operating jointly with North Hooe Mine as Tamar Consols, played a significant role in the early 1800s. Initially, it collaborated briefly with South Tamar Consols and Tamar Valley Mine in 1820-1821 under the title Bere Alston Mines. Situated on the north side of the Tamar River, South Hooe yielded notable silver content in the early 1800s, reaching up to 180 ounces per ton, with lead concentrations around 60%. In 1814-15, 3 tons of silver were extracted.

In 1820, a merger united South Hooe and South Tamar as South Tamar Consols, but by 1821, the entire entity was put up for sale. Operations resumed in 1835 at South Hooe, now under the name Tamar Silver-Lead Mine, with promising prospects. As the lode dipped southward, extensive workings extended up to a quarter-mile under the river. To facilitate mining, a 25-degree incline was driven between the 13 and 115 fathom levels, and Spurgin’s shaft was sunk to the 175 fathom level, equipped with an underground engine for hauling. Unfortunately, in 1851, a tragic incident occurred when fumes from the engine overcame workers in old workings, resulting in fatalities.

Ores from South Hooe were smelted at Weir Quay, where furnaces could process up to 300 tons per month. The average silver return was around 60 ounces per ton. Despite increasing returns with depth, mining ceased in 1885, 250 fathoms below adit.

The mine operated primarily from the engine shaft, sunk to 250 fathoms on a 15-degree east underlie. The 160 and 175 fathom levels were the most extensive, reaching out to 470 fathoms southward. From 1845 to 1876, Tamar Silver Lead and Tamar Consols collectively produced 14,640 tons of 62% lead ore and 326,300 ounces of silver. Additionally, from 1879 to 1882, 780 tons of fluorspar were extracted.

Galena, fluorite, and pyrite can still be found beneath the spoil heaps on the riverbank, though only small fragments are scattered among the pebbles and mud. However, occasional discoveries, such as a fingernail-sized flake of galena, tested positive for silver content of approximately 0.1% when dissolved in nitric acid and treated with common salt to produce a white precipitate.
