TENGRAPH® Online is a mapping system displaying the position of Western Australian mining tenements and petroleum titles in relation to other land information.

It gives a current and accurate picture of land under mining activity and is used to determine ground that is available for mineral exploration.
TENGRAPH® also provides direct access to these departmental systems:

• Mineral Titles Online (Mining tenement),
• Petroleum and Geothermal Register (PGR),
• WAMEX (Mining tenement open file exploration reports),
• MINEDEX (Mine site and mineral deposit information).

Please note: The Department of Mines and Petroleum (DMP) ceased to be a Designated Authority under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA06) on 1 January 2012.

Commonwealth petroleum titles, acreage releases and pipelines are no longer viewable in TENGRAPH. For all queries regarding administration of Commonwealth titles and pipelines refer to the National Offshore Petroleum Titles Administrator (NOPTA) website. For Commonwealth Acreage Release information refer to the Department of Resources, Energy Tourism website.
