VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 24, 2017) -

HIGHLIGHTS:

Fifteen Mile Stream: 36m @ 2.33 g/t from 112m, 16m @ 2.47g/t from 9.5m, 22m @ 1.86 g/t from 108m

Cochrane Hill: 18m @ 1.66 g/t from 65m, 13m @ 2.22g/t from 198m, 5m @ 5.50g/t from 48m

IDENTIFYING EXTENSIVE BROAD ZONES OF SHALLOW MINERALIZATION AT FIFTEEN MILE STREAM

DEPTH EXTENSIONS AT COCHRANE HILL

Atlantic Gold Corporation (TSX VENTURE:AGB) ("Atlantic" or the "Company") is pleased to report assay results received from drilling programs on the Fifteen Mile Stream and Cochrane Hill gold deposits where resource definition drilling on 25m x 20m centres is underway with the objective of upgrading resources to measured and indicated categories.

In particular, it is noted that assay results are now being returned from those holes at Fifteen Mile Stream drilled through the core of the anticline, and these are indicating considerable widths of attractive grades. Total widths of significantly mineralized intervals intersected in hole FMS-17-124 (see table below) aggregate to 78m @ 1.75g/t and in hole FMS-17-113, to 60m @ 1.73g/t. Previously reported holes from this same locale, FMS-17-104 and FMS-17-090, had recorded aggregated significantly mineralized intervals of 88m @ 1.79g/t and 36.5m @ 4.12g/t respectively.

The Company plans to use the results from the drill programs to undertake further analysis to determine the economic viability of the above-noted deposits which would include analysis of the economics of processing these deposits at the Moose River Consolidated ("MRC") processing facility by way of a Pre-Feasibility Study.

New assay results from the two drilling programs are reported as follows:

1. FIFTEEN MILE STREAM

Fifteen Mile Stream is located approximately 57km northeast of the central milling facility at Touquoy and is readily accessible by highway. Fifteen Mile Stream's current inferred mineral resources stand at 11.72 million tonnes at 1.55 g/t Au for 584,000 oz. New assay results reported herein are from a further 14 holes of the ongoing resource definition diamond drilling program. At this time 177 holes for 21,387 of the planned 25,000m have now been drilled and three drilling rigs are presently operating on the property with completion expected in a week's time.

Drilling Results:

The additional assay drill results continue to reflect those grades, widths and geometry of gold mineralization documented from the 1980s and 2011 drilling programs which support the current inferred resource estimate (see below). Mineralization occurs within argillites, greywackes and bedding-parallel quartz veins across the hinge zone and limbs of the E-W trending Fifteen Mile Stream (FMS) Anticline. The northern limb of the anticline dips moderately north, with the southern limb vertical to overturned (generally steeply north dipping). All holes are therefore declined to the south at various dips and hence true widths vary (see assay table below) depending on which limb of the anticline is intersected, and also depending on hole dip. Free gold is commonly observed, and in association with pyrrhotite and arsenopyrite.

Results are now being returned from a suite of holes drilled across the hinge zone of the anticline in the central part of the main Egerton MacLean zone, where drill access had previously been impeded owing to the location of certain wetlands. Apart from holes previously noted (FMS-17-090 and 104), attention is drawn here to new holes FMS-17-113 and 124 where appreciably mineralized intervals combine to down-hole widths of up to 78m. As well as the northern and southern limbs of the anticline, the central core or hinge zone of the anticline is now being shown to be well mineralized.

These shallow and widespread mineralized intersections across the limbs and core of this sub-horizontal anticlinal hinge zone are considered to be highly encouraging in the context of potential open pit extraction.

True width of the mineralization varies according to the dip of the enclosing stratigraphy and declination of the relevant drill hole. It is therefore noted for each intersection in the table above. Particularly in the Egerton-Maclean zone hole collars are necessarily located to minimise, though not entirely avoid, ingress to wetland areas and as a result hole declinations are adjusted to compensate for collar positioning. In many cases holes are drilled at different declinations from the same site. Sample distribution is not materially compromised.

The current resource estimate for Fifteen Mile Stream is as follows:

	Category	Tonnes (millions)	Grade (g/t) Au	Contained Au (oz.)
FIFTEEN MILE STREAM
	Inferred Resource	11.72	1.55	584,000
Resources that are not reserves do not have demonstrated economic viability

The Mineral Resource estimate for Fifteen Mile Stream is quoted at a cut-off grade of 0.5g/t. It has an effective date of February 16, 2015 and was prepared as part of a technical report in accordance with NI 43-101 by Mr. Neil Schofield, a principal of FSSI (Australia) Pty Ltd, released on April 2, 2015 on SEDAR.

2. COCHRANE HILL

The Cochrane Hill Gold deposit is located within trucking distance (approximately 80km) to the central milling facility at Touquoy and is readily accessible by highway (based on a Preliminary Economic Assessment dated October 14, 2014 prepared by Moose Mountain Technical Services). Mineral resources at Cochrane Hill currently comprise indicated resources of 4.5 million tonnes at 1.8g/t Au for 251,000 oz. and inferred resources of 5.6 million tonnes at 1.6 g/t Au for 298,000 oz.

New assay results reported herein are from a further 29 holes of the resource definition diamond drilling program. This program was completed at the end of April with a total of 177 holes for 26,575m having been drilled. The latter phase of the program targeted potential extensions of mineralization to the west of the main body of mineralization within an area of shallow wetland where particular regulatory approval was required, and west of the step out holes on section 2775E across highway #7. Nine additional holes were also drilled to test for depth extensions beneath the last, deepest, encouraging intersection on each of nine cross-sections east of 3000E. Examples of these deeper intersections from previously reported holes are 30m @ 2.61g/t (CH-16-126), 18m @ 2.52g/t (CH-16-052) and 11m @ 3.41g/t (CH-16-102).

Drilling Results:

These new assay results come largely from the wetland area to the west of the main body of mineralization and where the geometry of the mineralization continues to be fairly predictable and continuous, as a reasonably discrete, tabular, 70° north-dipping zone having a true width of approximately 15-20m in this area. Mineralization appears to be attenuating west of the highway #7 (around 2750E) though more assays here are pending. Mineralization, although narrowing, remains open to the east (east of 3500E).

Technical Disclosure

Fifteen Mile Stream

At Fifteen Mile Stream all assays are 50g charge fire assays conducted on whole-sample pulverized 1m samples of sawn, half NQ core with 1-in-10 duplicate assays and insertion of standards and blind blanks. Sample preparation and assaying is conducted at the Sudbury and Vancouver laboratories of ALS Canada Ltd, an entity having no other relationship with the Company. Core recovery is estimated for each metre and averages >97%, excluding occasional voids, usually <2m, representing historic underground workings. Wing samples to voids may be less than 1m to re-establish routine sampling on 1m intervals. Drill core in the hangingwall of the northern limb of the anticline where adjacent historic holes very clearly indicate this upper stratigraphy to be barren may not be sampled and assayed. Standards, blanks and duplicate assay results are acceptable.

Cochrane Hill

All core drilled at Cochrane Hill is assayed. All assays have been conducted on 1m whole-sampled pulverized samples of sawn, half NQ core and, where mineralization is expected, assayed by total sample screen fire assay with 2x fines fire assays, and insertion of standards and blind blanks. Sample preparation and assaying is conducted at the Sudbury and Vancouver laboratories of ALS Canada Ltd, an entity having no other relationship with the Company. In the hangingwall and footwall of expected mineralization samples are assayed by 50g charge fire assay with any mineralized samples (generally >0.5g/t), and adjacent samples as appropriate, returned for screen fire assay. With almost 600 such fire assayed samples having now also been screen fire assayed it is apparent that correlation of these duplicate assay results is sufficiently close to warrant ongoing assaying by fire assay alone. This methodology will apply to samples from the final 28 drill holes. Core recovery is estimated for each metre and averages >98%. Standards and blanks assay results are acceptable.

Results and updates from this drilling program will be reported progressively.

Wally Bucknell, Director of Exploration to the Company and a Qualified Person as defined by National Instrument 43-101 ("NI 43-101") has reviewed and approved the contents of this news release.
