Recent ‘landscaping’ has removed many features, but remains of leat, wheel pit, ore slide and crusher house are visible.

At valley bottom is the 1638 adit, much of it cut and cover. Its existence was forgotten until 1975. It appears the Taylors never used it, and Lewis Morris was unaware of its existance.



Year Activity
early 17C Worked for Sir Hugh Myddleton by Thomas Bushell. It was old at this time, and Lewis describes it as ‘an Antient British Open Cast and tho’ the upper ENd seems to have been wrought by the Patentees (Myddleton & Bushell). yet this work hath not been mentioned by any Mineral Writer … It is worked between 30 and 40 yards deep and to good Profit; but seems not yet to be deep enough’.
1795-1810 Mine lay idle.
1840s Re-started during the great mining revival, by which time working were only 20fm under adit, a 20ft wheel driving 4 inch pumps. Results disappointing.
1850 At the AGM, Taylor stated that £8,000 of ore was within sight, but complained about the former agent - calling the machinery ‘ill placed and ill constructed’.
1851 Sinking down to 45 fathom level, but no profits.
1862 A rich orebody was discovered when ait pushed to the east on south branch of the ore lode, the orebody rising almost to the surface. This could then be reached by driving adits into the hillside.
1863 119 men at work underground, and mine reached it’s final depth of 69 ft, at which the lode was barren.
1877 Last returns of lead ore.

Output since 1849 - 9,919 tons, with 200,000 ounces of silver.



Landowner lives above the site and is very sensitive about anyone looking around. (see Buddepit forum link)
