Although it was once a large and important mine, there are no known plans of its extensive underground workings, and there are few extant records of its output of tin ore. What is known, however, is that a total of about 276 tons of white tin was "coined" (i.e. recorded and taxed) at Tavistock, the nearest stannary town, between the years 1822 and 1831, and this may have been worth almost £30,000. The mine's most productive year was 1825, when 403 blocks of tin weighing over 1,220 cwt in total were coined.
