Guidelines for Assessment Reports: Nunavut Mining Regulations

The Guidelines for Assessment Reports: Nunavut Mining Regulations is presented as a plain-language summary of the requirements for submitting assessment reports to the Mining Recorder under the Nunavut Mining Regulations (NMR), and to assist report authors in filing reports that are accurate and complete under the NMR. The guidelines will be updated with new information once the Nunavut Map Selection initiative, which will allow online mineral claim staking and land tenure management, is adopted. This document is to be referred to in conjunction with the Nunavut Mining Regulations (NMR), which came into force April 1st, 2014. It is not intended as a substitute for the regulations.

Mineral tenure licensees who hold rights to one or more mineral claims must perform work in order to keep those rights. Licensees who hold prospecting permits and wish to claim reimbursement of the required charges must also perform work. This work must be documented in reports which meet the criteria in the Nunavut Mining Regulations (NMR) and in Schedule 2 of those regulations.

For further information about mineral tenure management in Nunavut, including permitting, the staking process, prospecting permits, or mining leases, please visit the Nunavut Mining Recorder's Office website.

The term 'assessment report' is used throughout these guidelines to refer to the work reports required by the NMR, as that is the most familiar industry term; this term can be read interchangeably with the term 'work report' used in the regulations. The definition of 'cost of work' is similar to the term 'assessment credit' under the old regulations.

The assessment report process

Assessment reports that document work completed on mineral claims or prospecting permits (mineral tenure) located on Crown land are filed with INAC's Mining Recorder for Nunavut. The intent of filing these reports is to assign the cost of the work completed to the mineral tenure it was completed on to fulfill the work requirement set out in the NMR. The reports must be submitted with the relevant forms as required by the Mining Recorder's Office (MRO).

Mineral Resources Division geologists review assessment reports as they are received from the Mining Recorder's Office, and have an internal service standard of 90 days, beginning from the date of receipt by Mineral Resources of the report from the MRO, to complete the review. If the reviewing geologist finds that there are areas in which a report does not comply with the NMR, they will send a letter to the report's author indicating what content needs to be revised; the author then has 90 days from receipt of the review letter to submit revisions to the reviewing geologist. On receipt of those revisions, the reviewing geologist will determine if they are sufficient to bring the report into compliance with the NMR.

Once the reviewing geologist has approved the technical worth of a report, that amount is reported to the Mining Recorder so that the approved cost of work can be allocated to the mineral claims or prospecting permits being reported on. The reviewing geologist will contact the report author to indicate the final cost of work that has been approved for that report.

The information contained in these reports serves to justify the expenses being claimed on mineral tenure (e.g. mineral claims and prospecting permits), and is released to the public after a three year confidentiality period. This industry-generated geoscience information, when combined with data released from government and academic research, contributes to the geological knowledge of the territory of Nunavut, and informs exploration and investment decisions.

Determining 'cost of work'

To qualify as a cost of work, expenditures must fall into the categories listed in the definition of "work" in the NMR. Please see NMR section 1 (1) for definitions of "cost of work" and "work". As per the definition of "cost of work", the following expenditures are not considered "work":

The following are also not considered to be "work":

Please do not include receipts, invoices, or other similar documentation with the report. Those items will be requested if necessary. Any costs that the reviewing geologist considers to be excessive in relation to the work being reported on will be subject to further inquiry.

The intent of the NMR is for exploration work to be done on specific mineral claims and for the associated expenditures to be applied to those mineral claims. Costs incurred in support of this work (e.g. food, accommodations, supplies, etc.) must be applied based on the amount of work done on the mineral claims and cannot be allocated globally to all mineral claims in a property.  Work must be done on a claim in order for costs of work to be applied to it, except in the case of grouping as per section 46 of the NMR.

In short, just because money is spent on an exploration project in Nunavut does not mean that the full amount will be approved as a "cost of work". Expenditures must meet the definition of "work" as it is set out in the NMR, and those expenditures that do not qualify as "work" will not be approved. Report authors with questions about whether an expenditure not listed above meets the definition of "work" can contact the geologists in the Mineral Resources Division at INAC's Nunavut Regional Office by email at:

Submitting an assessment report

When submitting an assessment to the Mining Recorder's Office, both assessment reports and simplified assessment reports must contain all administrative documentation as required by the Mining Recorder. A copy of the Statement of Expenditures spreadsheet document should be included with these documents, as well as with the report. The assessment report itself must include all information necessary to support the expenditures being claimed as a "cost of work", as well as any appendices required for the report (e.g. maps, raw geophysical data, assay certificates, contractors' reports, etc.). Specific criteria for the reports are discussed in the sections below.

The NMR require that as of April 1, 2014, assessment reports be signed off by a Qualified Person who is registered with the Northwest Territories and Nunavut Association of Professional Engineers and Geoscientists (NAPEG). The Nunavut Mining Recorder's Office cannot accept reports on work done after April 1, 2014 which have been signed off by Qualified Persons from other jurisdictions; please contact the Mining Recorder's Office for more information. Details on registering with NAPEG can be found on their website.

Writing an assessment report

Assessment reports and simplified assessment reports should include clear, detailed information on the following:

Simplified reports may be submitted under the requirements set out in Schedule 2, section 17 of the NMR, where the total costs of work are less than $20,000. Basic guidelines for simplified reports are included in this document. A more specific document intended for prospectors and others who might prepare simplified reports is being prepared.

Each assessment report should focus on work that was done on a property or project in a single program or field season, the new geoscience knowledge and results that were obtained, a discussion of those results, and conclusions and plans for future work. The first work report submitted for a project could be an exception, as those reports can cover up to two years of work. Discussion of previous work done on a property should be limited to a brief summary of a page or two. Whenever possible, it is better to provide a concise summary and a reference that interested readers may access for more complete information, than to provide an extensive description of work that was completed in the past. Work can be submitted up to 4 years after it is completed.

Hard copy report submission

Hard copies of assessment reports must be bound, and must be typewritten or printed on 8.5"x 11" paper. They may not be handwritten. Larger pages (e.g. maps, diagrams, sections, or spreadsheets printed on 11"x 17" paper) are acceptable provided one full edge is securely bound into the report and the page is folded to fit.

Larger format maps or figures which have not been bound into the report must be folded and placed in pockets, envelopes, plastic sleeves, or other suitable holders which are themselves bound into the report. Loose maps are not acceptable. All hard copy reports are scanned for digital archiving, and the available hardware is only able to scan maps up to 110 cm (44 inches) wide. As such, printed maps are requested to be no wider than 110 cm (44 inches).

All the text, figures, tables, etc. in a report must be legible. This includes items such as sample numbers or structural symbols on maps, and data contained in assay certificates. If the reviewing geologist cannot make out information in the report, or if the information will not scan clearly for digital archiving, revised versions of content that is legible will be requested. Eleven-point font is recommended for text and minimum 6-point font for the smallest labels in figures or maps. The minimum recommended print resolution setting is 300 dpi for text and 600 dpi for figures. Maps, sections, and diagrams inserted as figures should be in colour where appropriate, and at sufficient resolution to ensure legibility.

If CDs or other storage media (e.g. DVDs, USB sticks, etc.) containing raw data are submitted with hard copy reports, they must be attached to the report in some fashion and not submitted loosely. Each piece of storage media must be labeled with the company name, project name, report date, and the number of pieces being submitted (e.g., 'Disc 1 of 3'). NMR Sch. 2, s 3(1)(j)

Electronic format report submission

Under the NMR, assessment reports may be submitted in electronic format; however, the Nunavut Mining Recorder's Office is unable to accept electronic-format assessment reports via email because the secure transfer of confidential report files cannot be guaranteed. Electronic copies of assessment reports must be submitted in a format that can be read using the Mining Recorder's computer systems. Please submit reports in press quality PDF on physical storage media (e.g. CDs, DVDs, USB sticks, or external hard drives). Press quality PDFs can be created with Adobe PDFMaker or Acrobat Distiller. The converter has a "PDF Settings" dialogue box in which "Press Settings" can be selected.

All submitted storage media must be labeled with the company name, project name, report date, and with the number of pieces being submitted (e.g. 'Disc 1 of 3'). NMR Sch. 2, s 3(1)(j)

Images and maps in the report should be in colour whenever appropriate. As with paper reports, all maps, figures and diagrams should be produced at a resolution of at least 300 dpi. 600 dpi is preferred to preserve figure and/or picture quality.

PDFs must not be password-protected. Please ensure that the "Security Method" in "Document Properties" is set to "No Security" to enable the insertion of any necessary revisions by the reviewing geologist. Georeferenced PDF documents are acceptable as long as they meet the rest of the requirements set out in Schedule 2 of the NMR.

Content criteria for assessment reports

Title page

Assessment reports must have a title page that includes the project name, claim names and numbers, types of work done, for whom the work was done, who completed the work, the project's location (using the four corner coordinates of its bounding box), the dates during which the work was done, and the NTS 1:50 000 map sheet number(s) on which the work took place. This title page must be included on each volume of a report if the report has multiple volumes. An example is provided as a template at the end of this document. NMR Sch. 2, s 3(1), s 3(2) If the report covers multiple small parcels of mineral claims, a single bounding box that encompasses all parcels is sufficient to ensure that there is enough space on the title page for all the required information.

Title page – Electronic reports

Reports that are submitted in electronic format must also contain the title page information on a paper cover sheet submitted with the storage media containing the report, or as a 'readme' text file on each piece of storage media submitted. NMR Sch. 2, s 3(2)(b)(i-ii)


Figures must be numbered so they can be properly referred to in the text, and must include a caption.


Maps and sections must have a scale bar, a geographic reference (north arrow on maps; view direction on sections), an indication of coordinate system and unit of measurement, coordinate grid, and an appropriate legend that includes all symbols and colours used on the map or section. Maps must be in NAD27, NAD83, NAD83 (CSRS), or WGS84 with the datum and zone number (or projection, if applicable) indicated on each map. NMR Sch. 2, s 6(1)-6(3); s 9(1)-9(4)

According to the NMR, several specific maps are required to be included in an assessment report:

  • A map that includes the project's mineral tenure and identifies any adjoining mineral tenure belonging to other licensees. Each claim belonging to the company doing the assessment work must be identified with its claim number NMR Sch. 2, s 5(c)
  • A map that shows the area worked in relation to territorial boundaries, including any communities and any regional infrastructure (e.g. airstrips, camps, docks, winter roads, etc.) NMR Sch. 2, s 5(b)
  • A map of the regional geology of the project area NMR Sch. 2, s 5(a)
  • One or more maps showing the location of all surface samples, drill holes, or other data collection points, with legible identification numbers for each location. Inset maps should be used to display areas with high densities of data points NMR Sch. 2, s 5(d)
  • One or more maps that shows any grids used to perform work, such as sampling grids or ground geophysics traverse grids. Grid coordinates must be included NMR Sch. 2, s 9(2)
  • One or more maps that shows any geochemical or geophysical anomalies, if geochemical or geophysical work was done NMR Sch. 2, s 5(e)

Reference list

A reference list is required for all works cited in the report text, including any maps and figures. The Canadian Journal of Earth Sciences style is recommended for reference lists. When referencing assessment reports, the following format is suggested:

  • Author last name, initial(s). 2014. Assessment report on the Shiny Objects project. INAC Assessment Report #00001. Report prepared by J. Geologist for Raven Resources Ltd.
  • Full bibliographies are not required for assessment reports. Please only include sources that are directly referenced in the report in the reference list. NMR Sch. 2, s 4(e)


Several appendices are required in assessment reports:

  • a list or table of abbreviations and short forms used in the report or the appendices (e.g. in drill logs or sample descriptions). NMR Sch. 2, s 4(f)
  • the report author's Statement of Qualifications. NMR s 15(3)(b),s 40(2)(b)
  •  Only one Statement of Qualifications signed by a NAPEG-registered Qualified Person is required for a report.
  • the report's Statement of Expenditures. NMR s 15(4), s 40(3)

If work on an exploration program was undertaken by contractors (i.e. geophysics contractors), any contractors' reports must also be submitted, and must include any deliverables provided by the contractor to the company (e.g. large format maps, raw data, analytical certificates, etc., as applicable). NMR Sch. 2, s 16(1)(d)

The Statement of Qualifications should indicate the Qualified Person's professional affiliation, their place of employment and its location, and a statement declaring that they are an author of the report (as a report may have multiple authors). It must be signed and stamped with the Qualified Person's official stamp or seal. NMR ss 15(3), 41(2)

A suggested template for the Statement of Qualifications is as follows:

I, J. Geologist, indicate the following:

  1. I am a Professional Geoscientist affiliated with the Northwest Territories and Nunavut Association of Professional Engineers and Geoscientists (NAPEG);
  2. I am employed by [Company], headquartered in [City or town];
  3. I am an author of this report on the [Project name] project;
  4. I supervised the work being reported on in this report;
  5. This report is complete and correct to the best of my knowledge.

Requirements for specific types of report

Geological report requirements

Geological work assessment reports require a detailed description of the property's geology, including rock types, structural features, and areas of mineralization. The report must include a discussion of all results obtained from the geological work, and their relevance to future work on the property. Any geological maps produced from mapping programs must be included.

If prospecting took place, a table of samples along with descriptions and coordinates should be included, as well as a map showing traverse locations and a map showing the locations of samples taken. If drilling took place, a map showing the location of each drill hole is required, as well as drill sections and logs. The intervals of core sampled for assay and results of assays on those samples must be identified on each drill section. Please also indicate the location of any stored drill core. NMR, Sch. 2, ss 12(a-d), 13(a-d), 14(a-d)

If data compilation or literature review work is done (e.g. reprocessing of historical geophysical data from work done by a previous operator), the costs associated with that work may be acceptable as an expenditure provided that it leads to a new geological interpretation, a new deposit model, or another similar deliverable. Compilation work whose related expenditures are presented without any new results is not considered acceptable "work" under the NMR.

Geochemical report requirements

The type of geochemical survey performed (e.g. till sampling, grab sampling, stream sediment sampling, etc.) must be described, including details of the analytical process(es) used. A map showing sample locations is required, as well as any maps, or geochemical anomaly profiles produced. Please also include the raw data used to produce these maps and profiles. Cut-off grades should be indicated wherever relevant. A discussion of the survey's results is also required. NMR, Sch. 2, s 15(a-i)

If the geochemical work was done by a contractor, any report produced by that contractor, as well as the data collected and any other digital products produced (e.g. maps, profiles, etc.) should be submitted with the assessment report.

Assay certificates and similar analytical reports must be signed by a Qualified Person from the accredited lab that performed the analysis and must be submitted with the assessment report. The Qualified Person's signature must be present on a cover letter that indicates their accreditation and stamp, and/or on each assay certificate.

Geophysical or remote sensing report requirements

The type of geophysical survey performed must be described (e.g. airborne magnetic, ground magnetic, gravity survey, hyperspectral remote sensing, etc.). A map showing flight or traverse lines and their direction is also required, as well as any maps, tracings, or geophysical profiles produced. The raw data used to produce these maps and profiles must also be included. If underground geophysical surveys were performed, the location and orientation of the survey with relation to underground workings must be described. A discussion of the survey's results as it relates to the project is also required. NMR, Sch. 2, s 16(1-5)

If the geophysical work was done by a contractor, any report produced by that contractor, as well as the data collected and any other digital products produced (e.g. maps, profiles, etc.) must be submitted. NMR Sch. 2, s 16(1-5) 3D modeling data should be accompanied by viewing software that allows the data to be examined.

When submitting reports that include remote sensing work, please include the reference information and metadata for any images used in the report, including time and date taken, company purchased from, etc.

Environmental baseline study requirements

Environmental baseline studies will be accepted as part of assessment work in Nunavut, provided they meet the same criteria that other types of report must meet (e.g. they include maps, contractors' reports, discussion of results with reference to the project, etc.), and as long as they are performed in conjunction with other types of assessment work on the same mineral claims. In other words, a baseline study will not be accepted as a cost of work if it is the only type of work being reported on a particular claim during a particular reporting period. These studies must take place as components of a larger field program. NMR s 1(1)(c), definition of 'work'; NMR Sch. 2, s 4(t)

Criteria for Simplified Reports

Simplified reports can be submitted when work on a project has totaled less than $20,000, and when only excavation, sampling, or the examination of outcrops and surficial deposits were performed. NMR Sch. 2, s 2-11, 17(a-c)

The simplified report must meet the requirements set out under sections 2 to 11 of Schedule 2, excepting sections 4 (g), (m), (o), (p), and (q), and 5 (1) (a) and (e). A simplified report must contain the following components:

The simplified report must also include a signed statement from the individual who performed or supervised the work. A suggested template for the statement is as follows:

I, M. Prospector, indicate the following:

  1. I am the person who performed the work on the [Project] project, outlined in this report (or, 'I am the person who supervised the work on the [Project name] project', if the prospector did not perform the work);
  2. I am the tenure holder for all the mineral claims that make up that project; (or, [Person] or [Company Name] is the holder of the tenure, if the prospector is not the tenure holder);
  3. I am a resident of [Hamlet], Nunavut.
  4. I received assistance in preparing this report from [Person] (if the author received assistance).
  5. I am the author of this report.
