Mineral Exploration Assessment Reports

What is an Assessment Report?

Assessment reports on shelves

A Mineral Exploration Assessment Report is a report that describes work that has been done to advance the geological knowledge base of a mineral claim as per the Mining Regulations of the Northwest Territories Land Act.  The assessment report discloses to the NWT Mining Recorder's Office the specific operational, technical, and financial information of that work including geology maps, sample analyses and geophysical data for example. Assessment reports are released for public usage three years after submission.  Once released, the reports represent a vast source of information on the mineral resource potential of the NWT. NTGS provides accessibility to the information contained in assessment reports through its web-based information applications and walk-in information services in Yellowknife.

Accessing Assessment Reports

The Northwest Territories Geological Survey (NTGS) houses an archive of over 4000 Mineral Exploration Assessment Reports for the Northwest Territories from the 1940's to present.  All publicly available reports are available for viewing on request. These reports have been scanned and are available for searching and downloading through our Web Applications. When searching for NWT Assessment Reports start by querying our References Application. Select 'Assessment Report' as the reference type and enter the NTS map sheet of interest. Alternatively, try searching by author or area.  The more criteria used the fewer results are generated. Reports can be downloaded for free.

The Northwest Territories Mining Regulations

The District Geologists at the NTGS technically review assessment reports of exploration work filed for assessment credit under the Northwest Territories Mining Regulations.  The Mining Recorder's Office can provide more information on mineral tenure, licensing, and regulatory requirements in the Northwest Territories.  The Mineral Tenure Web Map can be used to view current data on mineral properties in the NWT.
