Diggings

Diggings is a term used in mining to describe excavations in earth from which minerals are extracted, as well as the sites and camps associated with such activity. In common usage, diggings can refer to both surface deposits exposed by removing overburden (placer or alluvial diggings) and underground excavations such as shafts, tunnels, and adits that follow ore bodies (hard rock diggings). The plural form is frequently encountered in historical accounts of mining districts and gold rushes, where prospectors worked informal or ad hoc claims.

Placers diggings involve extracting dense minerals that have been concentrated by water action, typically through panning, sluicing, or dredging. Lodes or hard rock diggings require deeper excavation to access ore in veins, and may involve shaft sinking, drifting, and the construction of adits to ventilate and drain the workings.

Prospecting and claim staking typically marked the beginning of diggings activity, with miners establishing camps around productive sites. Equipment ranged from hand tools such as picks and shovels to mechanical devices like windlasses, ore carts, sluice boxes, and rudimentary crushing or sorting gear.

Environmental and safety considerations: old diggings can present hazards such as unstable ground, collapsed tunnels, and water ingress, and may affect waterways through sediment or pollution. Modern regulation often governs land use, environmental protection, and the reclamation of abandoned diggings.
