The table below shows any historical notes about the location.
|Note||Date||Short Description||Note Text|
|2540||c1900||Location :||Driven about 16m into the Terrace between Smith's Gully and Jones Gully on the western side of Shepherds Creek. Two adits approx 30m apart, about 5m above the Bannockburn Nevis Road, situated approx 160m south of the school road intersection.|
|2541||c1900||Quartz Silica Sand||The quartz sand is from the Manuherikia group sediments. It is loose, fine, and fairly pure. There are sufficient impurities present in the form of fine-grained rather weathered mica, and probably clay, found as an extremely thin coating on some of the quartz grains. This rules out the sand as a raw material for optical glass or high quality glassware. However, it could still be used for ordinary glass manufacture, although a washing plant may be required to remove clay or iron stained horisons (?)|
|2542||c1900||General Note.||It appears that the tunnels may have been driven by one of James Lawrence's sons in search of coal.|
|2543||c1918||General note.||Alex Robertson (who was married to Annie Margaret Lawrence) worked the tunnels periodically until the 1950s. Samples were sent to Benhar for trials in the glazing of earthenware. Unfortunately the sand was found to be unsuitable for glazing. The main use of the sand was found to be for sand soap and for foundry moulding. The sand was mined by hand and bagged into flour sacks, transported to Cromwell raid head on Ted Lawrence's two ton Chev. truck. The sand was railed to Dunedin where the McLeods Soap Factory used it in the manufacture of sand soap.|
