 | Open File Mineral Tenement Data Packages |
| These packages contain a digital version of almost 47 years of exploration data held by DPI. It enables clients to research the details of previous exploration work conducted in their area of interest from the comfort of their own office.
The complete data package contains over 5700 reports from 1641 exploration licences (EL 1 - 5111). The earliest exploration licence was granted in July 1965 and the most recent became open file in June 2008. The earlier reports have been scanned from microfiche (or hardcopy if the microfiche were unclear) and are provided in multipage TIFF (.tif) format. Post 2001 reports submitted by companies are generally in Adobe Acrobat (.pdf) format with tabular data provided as .txt files with metadata headers. The microfiche are still available at Information @ DPI and the hard copy reports are stored at the Knowledge Resource Centre at Werribee. The data are organised by licence number - EL 1 to 999, EL 1004 to 1998, EL 2002 to 2694, EL 3000 to 3995, EL 4000 and EL 5000, as well as DL, MIN, ML, PAL, SL and TRL. Each DVD contains a Read Me file that gives an overview of what is provided and what software is needed. A Find Me file is also provided with the EL data to help locate the reports as some tenements have a complex history of changed numbers, cancellations and amalgamations, or have been joint reported with other licences. Complimentary update packages have been periodically made available. These contain tenement reports and accompanying data that became open file since June 2008 as well as additional data for previously expired licences. An update was released in June 2009, another in June 2010, and the latest update covers the period July 2010 – March 2012. Each release contains a map of Victoria with the most recently deceased licences highlighted.
