  • Laver Rock Mechanics Pre-Feasibility Study - Case Study

    Project Description Boliden is investigating the Laver low-grade copper deposit for potential future mining. The old Laver deposit was discovered in the 1930s, and was operated between 1938 and 1946. Mining was primarily conducted as small-scale underground mining, but a small open pit was also in operation at that time. The currently investigated deposit is of larger scale and with lower ...

  • Passive seismic horizontal to vertical spectral ratio (HVSR) surveying to help define bedrock depth, structure and layering in shallow coal basins

    Summary Trial passive seismic HVSR survey lines were carried out in the north-western part of the Wilga sedimentary basin in Western Australia, which is a small and shallow isolated sub-basin to the Perth Basin, sitting above rifted Archaean granite-gneiss basement rocks. The HVSR survey method was trialled to determine if it could resolve subsurface basin features quickly and cheaply. This ...
