(i) Resource statement cut-off grade is 0.45 g Au/t.

Dr. Bill Pearson, P.Geo., President and CEO of Coastal Gold, stated: "We are pleased with the results of the initial mineral resource on the Hope Brook tailings. The tailings resource is being considered in the preliminary economic assessment in progress as potential mill feed to either supplement the run of mine material or to provide stand-alone early feed for the project."

Mineral Resource Estimate

At the 0.45 g Au/t cut-off, Tailings Pond 1 contains an estimated 2.6 million tonnes grading 0.95 g Au/t and 0.10% Cu, containing 80,000 ounces of gold and 5.9 million pounds of copper. Tailings Pond 2 contains an estimated 2.3 million tonnes grading 0.75 g/t Au and 0.07% copper containing 54,400 ounces of gold and 3.6 million pounds of copper.

The combined total inferred mineral resource estimate for both ponds is 4.9 million tonnes grading 0.85 g Au/t and 0.09% Cu, containing 134,500 ounces of gold and 9.5 million pounds of copper (Table 1). All tailings pond resources are classified as Inferred and as such, it cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category.

The mineral resource estimates are presented in Table 2 below at different cut-off grades to demonstrate the sensitivity of the mineral resources to change in grade. Approximately 40% of the resource in Tailings Pond 1 is present at the 1.0 g Au/t cutoff grade indicating potential for initial production at higher grades.

Notes on Mineral Resource Estimation Methodology:

1.  Mineral resources are estimated in conformance with the CIM Mineral
    Resource definitions referred to in NI 43-101 Standards of Disclosure
    for Mineral Projects. Pierre Desautels, P.Geo., Principal Resource
    Geologist, and Jay Melnyk, P.Eng., Principal Mining Engineer, both of
    AGP Mining Consultants and Qualified Persons under NI 43-101 who are
    independent of the Company, have prepared and authorized the release
    of the mineral resource estimates presented herein. The vibracore drill
    hole database developed by Coastal Gold was validated by Michael
    Cullen, P.Geo., of Mercator Geological Services, a Qualified Person as
    defined under NI 43-101 who is independent of the Company.

2.  Bulk densities were determined by SGS Canada Inc. for a representative
    number of tailings samples using industry standard methods. The bulk
    density used, 1.65 t/m3, is an average of six determinations made on
    tailings samples using a compacted bulk density measurement.

3.  The volume of the two tailing ponds was described using a 3D wireframe
    envelope that was developed by Coastal Gold. The wireframes were based
    on a combination of vibracore drilling results and historic topographic
    information. The two wireframes describing Tailings Pond 1 and Tailings
    Pond 2 were validated by AGP and found to be acceptable for use in the
    resource model.

4.  The grade model was interpolated using a conventional inverse distance
    squared, interpolated model based on 2 m length weighted composites of
    the tailing assays.

5.  No top cut was applied to the raw assays due to the normal distribution
    exhibited by both gold and copper raw assays. Drilling patterns for the
    vibracore holes were on a 100 x 100 m grid and the model was
    interpolated in three passes from 100 x 100 m, to 175 x 175 m, and
    finally 250 x 250 m.

6.  A geological block model was generated using GEMS© software. The
    block model matrix size is 25 metres by 25 metres by 50 metres. The
    volume reporting used partial models where the percentage of each block
    within the 3D tailing wireframe envelope is used to calculate the
    volume of the material.

7.  A cut-off of 0.45 g/t was determined using a reduced milling cost from
    $12 per tonne as applied to rock, to an estimated cost of $10 per tonne
    where decreases in power consumption, and balls and mill liners are
    partially offset by the dredging and pumping costs. It is also assumed
    that the G&A cost would be covered by an open pit operation on the Hope
    Brook deposit. An assumed 49% recovery at a price of $1,400 per ounce
    gold, results in a cut-off of 0.45 g/t for the tailing material.
    Virtually all blocks in the pond models are above that value, therefore
    AGP concluded both ponds have reasonable prospect for economic
    extraction.

8.  The rounding of tonnes as required by NI 43-101 reporting guidelines
    may result in apparent differences between tonnes, grade and contained
    ounces.

9.  Mineral resources that are not mineral reserves do not have
    demonstrated economic viability. The estimate of mineral resources may
    be materially affected by environmental, permitting, legal, title,
    taxation, sociopolitical, marketing, or other relevant issues.

10. The quantity and grade of reported inferred mineral resources in this
    estimation are uncertain in nature and there has been insufficient
    exploration to define these inferred mineral resources as indicated or
    measured mineral resources and it is uncertain if further exploration
    will result in upgrading them to indicated or measured mineral
    resources.

Metallurgy

Two composited tailings samples were collected from the 2013 vibracore sampling program and submitted to ALS Metallurgy for flotation and cyanidation testwork under the direction of Mr. Lyn Jones, P.Eng., of AGP Mining Consultants. Leaching tests on high-grade (1.2 g/t Au) and low-grade (0.8 g/t Au) tailings composites resulted in cyanide leach gold extractions of 63.6% and 45.6%, respectively. The results were found to be consistent with the leach tests from previous testwork completed in 2012 (see press release dated September 19, 2012) that indicated regrinding and re-leaching of the tails would result in extraction of 49% of the contained gold from a composite sample grading 1.05 g/t Au.

In addition, a single flotation test on the high-grade tailings composite grading 0.09% Cu (and using the optimized conditions from the Hope Brook Master Composite test program conducted in the fall of 2013) indicated a copper recovery of 61% to an open-circuit second cleaner concentrate grading 21.4% Cu. Further testwork is required to characterize these samples and optimize the metal recovery.

Shares-for-Debt Settlement

Coastal Gold has entered into a shares-for-debt settlement agreement whereby Coastal Gold will issue 245,000 common shares at a deemed price of $0.05 per share in settlement of dated accounts payable owing to a former employee of Coastal Gold in the amount of US$12,250. The shares-for-debt settlement is subject to the approval of the TSX Venture Exchange.

ABOUT COASTAL GOLD

Coastal Gold is a Canadian mineral exploration company listed on the TSX Venture Exchange under the symbol "COD". Coastal Gold's flag ship property is the Hope Brook Gold Project located in southwestern Newfoundland, which has 19.9 million tonnes at 1.93 g Au/t for 1,239,000 ounces of indicated mineral resources and 1.3 million tonnes at 3.22 g Au/t for 138,000 ounces of inferred mineral resources. In addition, there are inferred mineral resource in the tailings of 4.9 million tonnes at 0.85 g Au/t and 0.09% copper containing 134,500 ounces of gold and 9.5 million pounds of copper. Coastal Gold is currently completing a Preliminary Economic Assessment (PEA) on the Hope Brook Gold Project.

SAMPLING, ASSAYING AND QUALITY CONTROL

The vibracore drilling program is a low impact coring method that allows for recovery of unconsolidated sediments using a 4 inch diameter aluminum core tube. The tailings core were logged, photographed and then split in half with one-half sent to the laboratory for analysis and the other half retained and stored on site. All core samples were prepared and assayed at ALS Minerals, with sample preparation done in Sudbury and analytical work done in North Vancouver. All locations of ALS Minerals are ISO 9001:2000 certified. The entire sample received was dried, weighed and crushed to = 70% passing 1mm. A sample split of up to 1000g was then pulverized to = 85% passing 75 microns (200 mesh) to produce a homogenized sample. A 50g aliquot was used for fire assaying with an atomic absorption (AA) finish to determine gold concentration using method Au-AA25. Copper was initially analyzed using a four acid digestion ICP (inductively coupled plasma-atomic emission spectrometry) method ME-ICP61. Any results for copper greater than 10,000 ppm were assayed further by a four acid digestion and "ore grade" ICP method. Internal quality control included the use of blanks, duplicates and standards in every batch of samples. The Company also conducted internal check assaying using certified external reference standards and blanks. Regular external check assays were performed at a second certified Canadian commercial laboratory. Coastal Gold also inserted external reference standards as well as blank silica sand in each sample batch as a further external check.
