Sunset Clause Release of Exploration Reports
Under Regulation 96(4) of the Mining Act, Mineral Exploration Reports held by the Department for 5 years may be released to Open File.
On 11 June 2007, the Department will begin releasing reports submitted during the periods:
- January 1984 to December 1987
- January 1991 to October 1997
Spreadsheets listing these reports are provided below in Microsoft Excel format, which can be sorted by column attributes. The spreadsheets include:
- Report 'A' number
- Date submitted
- Time period of the report
- The WAMEX title
- The tenements in the reports
- The current tenement holder/s of the tenements covered by the report, or subsequent tenement granted in renewel or substitution for the tenement/s in the report. Where a tenement may have died, the holder at that time is listed.
Most reports have multiple entries. This allows searching on all tenement holders and tenements associated with individual reports.
If a report in the list is requested for viewing, the Department will charge $50 to retrieve a hard copy or $20 for a digital copy (where available).
Objections to release
Regulation 96(5) of the Mining Act gives the current holder of a mining tenement covered by the report, or any subsequent tenement granted in renewal of or substitution for such a mining tenement, the right to object to the release of the report.
These objections must be in writing, with specific details justifying the request for non-release of reports, and must specify the 'A' number of the report.
Objections which are most likely to be considered favourably will fall within the following categories:
| Reason | Documentation or further information required from tenement holders |
| Existence of previously undisclosed resource estimates or other information that is likely to influence the stock market valuation of the tenement holder | Identify the particular resource estimate or information and explain why it will influence the stock market |
| Continuation of commercial agreements entered into prior to promulgation of Regulations 96(4), (5), and (6) of the Mining Regulations that relate to rights in exploration data between a tenement holder and another party (ie.pre. 1995) | A copy of the relevant agreement |
Objections should be submitted in writing to:
