GENERAL HISTORY OF WELSH MINING

Many other minerals were mined, including zinc, iron, manganese and sulphur. In 1843, gold was discovered in Gwynedd and this created a new mining industry. Towards the end of the century, however, large deposits of lead and copper were discovered in Spain, South America and Australia and it was cheaper to import these than buy the home produced product. By the end

Rock Soil Sampling

19.07.2013Soil sampling is a basic technique of mineral exploration. Cheaper than drilling, sampling can be used to quickly establish the existence and extent of hoped for mineralisation. Initial geophysical and other remote sensing methods are used to target a geological structure which may contain mineralisation. Soil sampling can either stop a project

The 4,050 elevation drift adit was extended 750 feet and two new drift adits were driven, one 110 feet above, and the other 100 feet below. Drifting in the 4,050 elevation adit reportedly exposed an ore shoot over a length of 490 feet 3ut work in the adits above and below and in connect- ing raises showed less regular gold deposition. A total

Adit

Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally
