TENGRAPH Web is a spatial enquiry and mapping system displaying the position of Western Australian mining tenements and petroleum titles in relation to other land information. It provides a current and accurate picture of land under mining activity and is used to determine ground that is available for mineral exploration.


With the introduction of Tengraph Web, Tengraph Online will be decommissioned Friday 13th December 2019.

Tengraph Online was decommissioned

On the 13th December 2019 Tengraph Online was decommissioned.

Tengraph Online was first introduced in July 1999, using citrix virtual desktop technology to enable the delivery of the Tengraph enquiry module to external users. Which at that time was a significant achievement.

Previously access to Mineral Title and other spatial information was only available via access to the Tengraph Enquiry module at customer services counters in Perth and the Regional Mining Registrar Offices.

The change from Tengraph Online to Tengraph Web is part of an ongoing program to replace and modernise the entire Tengraph system which was first introduced in 1994.
