According to Iceland Review, borehole samples in Iceland indicate that gold may be mined there. Studies are on-going as to whether the gold content in the rock is significant enough to justify and pay for the processing. Geosynthetic containment systems have become vital to controlling mining-related pollution while creating efficiencies in the processing system: product is not lost. Learn more here.;

Vector Engineering, has expanded its central geotechnical laboratory, which services the mining and solid waste sectors. The major addition involves a new loading system for testing pipe deflection and geomembrane liner puncturing. Vector's lab can now simulate heap heights exceeding 200 meters. Also, Vector has increased the load capactiy of its large scale direct shear apparatuses to 200 psi, almost twice their previous limit. Learn more here.;
