The new mine was to be centred on Woolf's Shaft, which was to have a second-hand 80-inch pumping engine. The 80-inch cylinder engine, with 10-foot outdoor stroke and 9-foot indoor stroke, was built in 1868 by Harvey's of Hayle and installed at Batter's Shaft of West Chiverton Mine. It was designed by Matthew Loam and erected by Loam and Sons of Liskeard; the contract price for the engine with three boilers was £2,750. It was started in August 1869 and was described by the Mining Journal as "one of the most finished and perfect engines ever made in Cornwall".

The engine was bought back by Harvey's (for £1,250) after the mine closed in 1882 and stored at Hayle until 1899. It was re-erected at Garland's Shaft, Gwennap United Mines, but only worked for seven months in 1904; it was offered for sale in January 1905 and bought for £1,525 by Condurrow United in 1906. The engine was installed in a new engine house built in about 1907; work originally started on the north side of the shaft but after the foundations were cleared it was discovered that the ground was weak and the house was consequently built on south side.

Four new Holman boilers were to provide the steam.  In honour of the company chairman the shaft was to be renamed Neame's Shaft and the 80-inch was to be called Neame's Engine.  Unfortunately for this gentleman, the Cornish have a habit of persisting in the names they know, and the shaft and engine were always known locally as 'Woolf's', as they are today.  In 1910 Condurrow Mines Ltd was formed to take over from the previous company.  Little ore was produced and the mine closed in 1914.  The engine was sold to Holman's for scrap in 1916. 

The engine house stands today on the crest of the high ground overlooking the valley of the Great Flat Lode and can be seen for miles around, even (with binoculars) from Penzance.  The house is well-built and in a generally good condition; it is listed Grade II*.
