Forward looking information in this presentation includes, but is not limited to, statements with respect to: plannedexploration activities, the results and success of such activities and the timing thereof; completion of additional metallurgical results, the timing and results thereof; preparation and filing ofan updated NI 43‐101 technical report and the timing thereof; and potential acquisitions and expenditures associated with such. Forward‐looking information involves known and unknownrisks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance orachievements expressed or implied by the forward‐looking information. Such factors include, among others, risks related to government regulation; actual results and success of exploration,development and production decision if any; changes in project parameters as to plans continue to be refined; the ability to enter into joint venture or to acquire or dispose of propertyinterests; fluctuations in the price of gold; accidents and other risks of the mining industry; ability to obtain financing; and delays in obtaining governmental approvals or financing.

Although Nighthawk has attempted to identify important factors that could cause actual results to differ materially from those contained in forward‐looking information, there may be otherfactors that cause results not to be as anticipated, estimated or intended.

MINERAL RESOURCESThe Company has defined inferred mineral resources in accordance with National Instrument 43‐101 ‐ Standard of Disclosure for Mineral Projects (“NI 43‐101”) in respect of the Colomac GoldProject.

This presentation uses the term “inferred” mineral resources. United States investors are advised that while such term is recognized and required by Canadian regulations, the United StatesSecurities and Exchange Commission does not recognize it. “Inferred mineral resources” have a great amount of uncertainty as to their existence and as to their economic and legal feasibility.It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may notform the basis of feasibility or other economic studies, except in limited circumstances. United States investors are also cautioned not to assume that all or any part of an inferred mineralresource exists, or is economically or legally mineable.

QUALIFIED PERSONSAll scientific and technical information relating to the Colmac Gold Project is based on and derived from the NI 43‐101 report entitled “Technical Report and Mineral Resource Estimate Updateon the Colomac Property of the Indin Lake Project, Indin Lake Belt, Northwest Territories, Canada” date of June 17, 2013. Technical report was prepared by Mr. Ian D. Trinder, M.Sc., P.Geo. ofA.C.A. Howe International Limited who is an independent “Qualified Person” under NI 43‐101. The full report is available from the Company’s corporate website www.nighthawkgold.com orunder the Company profile on SEDAR at www.sedar.com.

All scientific and technical information in this presentation has been reviewed and approved by Dr. Michael Byron, Ph.D., P.Geo., the Company’s President & CEO, who is the 'qualified person'for the purpose of NI 43‐101.

GENERAL AND ADDITIONAL INFORMATIONAdditional information regarding Nighthawk is filed under the profile of Nighthawk on the SEDAR website at www.sedar.com, and readers are advised to refer to such documents for further information.

Inferred Mineral Resource Estimate (Effective at June 17, 2013)

Notes:1. A block cut‐off value of 0.6 g/t Au was applied to all resource blocks.2. Tonnes and ounces have been rounded to reflect the relative accuracy of the mineral resource estimate; therefore numbers may not total correctly.3. Mineral Resources were calculated with commercial mining software.4. For 2013 updated Colomac and Goldcrest block models: Drill holes traces showing lithology and gold grade were reviewed in plan and cross section. Geological domains were created using Leapfrog Implicit Geological 

Modeling Software. Assays with each domain were top cut to 31 g/t and then composited to regular 5ft intervals. Block model grade interpolation was undertaken using Ordinary Kriging (OK).5. For 2012 Grizzly Bear, 24 and 27 block models: Drill holes traces showing lithology and gold grade were reviewed in plan and cross section to generate mineralised domains. Assays with each domain were top cut to 31 

g/t and then composited to regular 5ft intervals. Block model grade interpolation was undertaken using Multiple Indicator Kriging (MIK). Refer to Lee and Trinder (2012).6. The resource estimate was prepared by Leon McGarry, B.Sc., Geologist, ACA Howe and supervised by Ian Trinder, M.Sc., P.Geo., ACA Howe.7. Gold price is US$1500 per ounce.8. A default average specific gravity (SG) value of 2.7 has been used.9. Mineral Resource tonnes quoted are not diluted.10. No Measured or Indicated Resources or Mineral Reserves of any category are identified.11. Mineral resources are not mineral reserves and by definition do not demonstrate economic viability. This mineral resource estimate includes Inferred mineral resources that are normally considered too speculative 

geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these Inferred mineral resources will be converted to the measured and indicated resource categories through further drilling, or into mineral reserves, once economic considerations are applied.

Highlights of Preliminary Metallurgy (1st & 2nd Generation) No adverse materials detected

Variation in rock hardness of all test samples was minimal indicating that the material is relatively homogeneous host rock

The master composite sample, having a head grade of 1.81 grams per tonne gold measured by fire assay, generated favourable recoveries for all process options, including heap leaching, flotation, and gravity separation. On the higher grade material, head grades varied significantly between the fire assay and screened metallic assays due to the nugget effect of gold within the deposit

Gold extraction by flotation ranged from 94.1% ‐ 95.5% on the lower grade, with maximum recoveries achieved at F80 151 microns, and between 90.7 – 94.6% on the higher grade, with maximum recoveries achieved at F80 75 microns

Cyanide heap leaching of minus 12,700 micron material reported up to 81.8% gold recoveries, perhaps an option for lower grade material which would otherwise be considered waste

Cyanidation of ground rock increased gold recovery significantly up to 96.5% on the lower grade and 98.0% on the higher grade.
