Northquest Reports Initial Mineral Resource Estimate for Vickers Gold Zone of Pistol Bay Project

Northquest Ltd. ("Northquest" or "the Company") is pleased to report its initial mineral resource estimate for the Vickers Gold Zone of the Pistol Bay project in eastern Nunavut, Canada. The mineral resource estimate was prepared by Roscoe Postle Associates Inc. ("RPA"). The technical report supporting this mineral resource estimate (the "Technical Report") will be filed on SEDAR within 45 days.

In addition to the initial mineral resource estimate of the Vickers Gold Zone, the Technical Report will also describe in detail the nature and distribution of 16 other gold occurrences on the Pistol Bay property for which there has been a minor amount of drilling by the Company.

The mineral resource estimate is confined to analysis of exploration work conducted on the Vickers Zone at the Pistol Bay project and it is based on 69 drill holes totalling 17,240 m at the Vickers Zone. The mineral resources are provided by domain in the following table. There are no resources included in the mineral resource estimate relating to Domains 107 and 108, which are located outside of the Whittle resource shell.

Domain Category Tonnes

1. CIM definitions were followed for classification of mineral resources.
2. Mineral resources are estimated at a cut-off grade of 1.25 g/t Au.
3. Mineral resources are estimated using a gold price of US$1,500 per ounce.
4. Assays were capped at 40 g/t Au.
5. Bulk density varies from 2.70 g/cm3 to 2.79 g/cm3 based on lithology.
6. The resources are constrained by a Whittle pit shell.
7. Numbers may not add due to rounding.
8. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and there is insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.
9. The effective date of the mineral resource estimate is March 31, 2016.

RPA is not aware of any known environmental, permitting, legal, title, taxation, socioeconomic, marketing, or other relevant factors that could materially affect the resource estimate.

Mineral Resource Assumptions

RPA prepared the initial mineral resource estimate for the Vickers Zone using block models constrained with 3D wireframes on the principal mineralized domains. Values for gold were interpolated into blocks using inverse distance squared (ID2). The Vickers Zone block model has 5 m by 5 m by 5 m whole blocks with the model origin at 507,400E, 6,910,000, and 50 m elevation. It has 240 columns, 200 rows, and 70 levels for a total of 3.36 million blocks.

RPA has estimated the Vickers Zone mineral resources using a cut-off grade of 1.25 g/t Au. Only those blocks contained within the preliminary pit shell are reported as a mineral resource. For reporting of open pit mineral resources, an open pit shell was produced using Whittle open pit optimization software. Only classified blocks greater than or equal to the open pit cut-off grade and within the open pit shell were reported. The operating parameters for the optimization and cut-off grade estimate are summarized in the following table.

Item Value
Au US$1,500/oz Au
Exchange Rate (C$/US$) 1.30
Reference Mining Cost $3.50/t mined
Processing and G&A costs $75.00/t mineralized material
Average Recovery 95%
Maximum Pit Slope 50°
Estimated Cut-off Grade 1.25 g/t Au

Sampling and Data Verification

Northquest diamond drilling data from 2012 to 2015 was used for the resource estimate. The BTW diameter (42 mm) core was cut in half with a rock saw and sent to accredited laboratories for screen metallics gold fire assays. Northquest's quality assurance and quality control (QA/QC) procedures included the insertion of standards and blanks and sending samples to a secondary laboratory for check assaying. The QA/QC results confirm that the assays from 2012 to 2015 are acceptable to support the resource estimate. RPA used the assay certificates to verify 74% of the resource related samples in the drill hole database and found no errors.
