Northern Territory mining records: STRIKE, GEMIS and report history
A practical route through spatial titles and geoscience, more than 30,000 open-file mineral exploration reports and community-held place knowledge.
STRIKE maps tenure, occurrences, drillholes, samples and other geoscience. GEMIS holds open-file mineral exploration reports; its public collection displayed more than 30,000 reports when reviewed. Annual and final reports become public under stated rules, while expenditure and production release is limited.
Use each system for the question it can answer.
A map, title summary, report, archive file and family recollection are different evidence classes. The sequence below preserves those differences so a lead does not become an unsupported fact.
- 01Spatial tenure and geoscience viewer
STRIKE ↗
What it holds. Mineral and energy tenure, occurrences, drillholes, wells, geochemical samples, maps and downloadable data.
Boundary. Public mapping does not grant access and may intersect Aboriginal land, sacred sites, pastoral interests and other regulated areas.
- 02Open-file report repository
GEMIS mineral exploration reports ↗
What it holds. More than 30,000 mineral exploration industry reports and data in the displayed public collection.
Boundary. Reports reflect their submission date and purpose. Historical results must not be presented as current resources or reserves.
- 03Coverage and release guidance
NT exploration reports and data guidance ↗
What it holds. Explanation of statutory exploration, drilling, geophysical and geochemistry data and the path to GEMIS and STRIKE.
Boundary. Reports begin confidential and become available under statutory time or title conditions.
- 04Reporting and confidentiality guidance
NT mineral-title reporting guidance ↗
What it holds. The public-release timing and limits for annual, final, expenditure and production information.
Boundary. Summarised expenditure or production data cannot be expanded into undisclosed asset economics.
From family note or map point to a cited record.
- 01Write the known facts. Exact source wording, name variants, place, date range, commodity or material, company and identifier.
- 02Locate, do not conclude. Use the spatial viewer to find the right district, layer and record ID. Save the layer name and access date.
- 03Open the underlying document. Follow title, report, plan or archive references. Record its creator, date, purpose and access conditions.
- 04Test aliases and chronology. Compare former company, mine, lease, field and locality names; do not merge nearby records by proximity alone.
- 05Separate present from past. Historical geology, production, ownership and sale events do not establish current status, value or rights.
- 06Add family context carefully. Label direct experience, family recollection and interpretation; document permission and the item’s provenance.
Geology is not a product sheet.
Remote-country research must not turn public coordinates into an access invitation. Landholder, title, environmental, sacred-site, cultural-authority and safety requirements remain separate.
Use the Northern Territory register for our published mine and quarry records, then return to the issuing authority for current decisions.
The public system can show the file. Families often explain the place.
A field-party name, camp, pastoral station, report number, old map-sheet reference or former worker’s route can help locate a report without publishing a sensitive site.
Using these records for an old sale or a possible listing
Public title, project and company records can help identify an asset and its history. They do not prove that an asset was legally transferred, is currently for sale, has a valid mandate or can be valued from public data. Historical sale pages require an express completion disclosure or remain labelled as publisher-reported. Current owners can register an asset confidentially, but Mines & Quarries does not market, negotiate or transact while the licensed brokerage gate remains closed.
