Our Story
ENMINTECH was established as Energy and Mineral Technology International in 2017 to provide high quality professional surveying, design, and supervision services and technologies to the energy, resource, and construction sectors in Indonesia.
Based in Jakarta, we have undertaken numerous mineral resource and reserve estimates, spatial and geophysical surveys, site validations, and pit optimisations for projects in pre-feasibility and feasibility stages, either independently or jointly working with internationally recognised mine engineering and construction consulting firms.
We are IUJP certified (#073/EMT/IUJP/IX/2019) to comply with local regulations, which require that all resource sector work must be carried out by a licensed company.
