Mineral exploration reports (WAMEX)

Mineral explorers are required to report annually on their exploration projects under Western Australian legislation. After a period of confidentiality, the exploration reports and data are made available to the public. These are referred to as open-file reports. Mineral exploration open-file (public) reports are stored in the Western Australian Mineral WAMEX database. Access is free of charge, and copies of the reports are available for download.

Mineral exploration report compilation and lodgement

Reports may be compiled and submitted online using a wizard. If you already have an ex login, go to “my account”, and add WAMEX online reporting to your list of accessible online systems. First-time users will be prompted by the system to register.

If the report has been lodged using the online system, then data requested by the Department of Mines, Industry Regulation and Safety (DMIRS) should also be submitted through the same system.

Annual release of mineral exploration reports

Mineral exploration reports held by the department for five years may be released to the public, under Regulation 96(4) of the Mining Act - the ‘Sunset Clause’.

Each year at the beginning of March, the proposed list of reports that are planned for release are published on the department's website and they are advertised in the Mining Notices of the West Australian and the Kalgoorlie Miner. There is a period of 2 months during which the current tenement holders can study the list and object in writing to the release of any report.

From early May, the department releases the reports that have no objections. In May 2017 reports to be released are those submitted during the period:

  • 1 January 2011 to 31 December 2011

Reports to be released include:

Reports which have been released to the public will not be withdrawn if an objection is received subsequent to the report's release.

Objections to release of mineral exploration reports

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, has the right to object to the release of the report under Regulation 96(5) of the Mining Act.

Submitting objections

All objections MUST be in writing, include the ‘A’ number (Accession number of report), and specifically detail the page numbers and paragraphs in each report that justify the request for non-release of reports.

Unless otherwise stated, the only objections that will be considered are the following:

  • The existence of previously undisclosed resource estimates or other information that is likely to influence the stock market valuation of the tenement holder. Supporting evidence to include: identification of the particular resource estimate or information and an explanation why it will influence the stock market.
  • The 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 (i.e. pre 1995). Supporting evidence to include a copy of the relevant agreement.

Objections should be submitted in writing, in two associated documents as follows:

  • a covering letter
  • a ‘read only’ PDF file or preferably a ‘read only’ Excel spreadsheet.

Objections to the release of reports should be addressed to the Director Geological Survey, and emailed to sunsetclause@dmirs.wa.gov.au

All objections will be acknowledged.
