GDMS is a 3D, integrated cloud-based technology for safe tailings storage facility (TSF) management. Equipping operators and executives with up to the moment data for how best to achieve this goal, GDMS facilitates transparent engagement, disclosure and decision making from a mine’s conceptualisation to closure. The GDMS operator dashboard simplifies conformity with the GISTM, providing an integrated knowledge base for the design, construction, operation and monitoring of TSFs. Ultimately a TSF design and management plan backed by GDMS offers complete transparency, from public disclosure accountability to a company’s capability to achieve zero harm to people and the environment.
