Atlantic Gold reports additional results from the Phase 3 Resource Expansion drill program at Fifteen Mile Stream

Fifteen Mile Stream is located approximately 57km northeast of the central processing facility at Touquoy and is readily accessible by highway. Fifteen Mile Stream's current measured and indicated mineral resources stand at 10.59 million tonnes at 1.33 g/t Au for 452,000 oz. at 0.35g/t cut-off grade.  Inferred mineral resources amount to 6.64 million tonnes at 1.12 g/t Au for 240,000 oz. at 0.35g/t cut-off grade (see Company announcement July 21, 2017)¹.

As per previous news releases the objectives of the Phase 3 Resource Expansion drilling program are to identify additional gold resources immediately peripheral to those resources previously defined at Fifteen Mile Stream and Cochrane Hill. At Cochrane Hill and at Fifteen Mile Stream – particularly at the Hudson and Plenty zones, upgrade previously defined inferred resources to measured and indicated categories, and seek additional new resources within the 350m gap between the Plenty and Egerton MacLean zones at Fifteen Mile Stream.

2018 drilling has recently re-commenced with three drilling rigs presently operating at the Plenty deposit. Twenty holes for 2217m have so far been completed. Up until the end of 2017 a total of 185 holes for 21,000m had been drilled at Fifteen Mile Stream.  Holes are generally drilled on 25m x 20m centres, although for the first-pass drilling along the 350m gap between Plenty and Egerton MacLean holes have been drilled on 50m-spaced sections.

Assay results have now been received from a further 36 holes, with about two-thirds of all assays expected from this program having now been received. Assays reported here from Egerton MacLean and Hudson, the eastern and western deposits respectively along the Fifteen Mile Stream anticline, are from widely distributed holes testing the peripheries of these deposits as presently known. Best result is the shallow high grade intersection (20m @ 21.9g/t including 1m @ 419g/t) towards the western end of Egerton MacLean which, at a vertical depth of only 30m, infills an information gap between surface and mineralization intersected in deeper holes beneath.

At Plenty, infill and step-out drilling westwards on 25m-spaced sections is underway to enable definition of measured and indicated resources, as upgrade from existing inferred resources. Drilling continues to outline a steep, northerly dipping, tabular zone of gold mineralization over more than 300m strike length, defined both by wide intersections of moderate grades (eg. 16m @ 1.05g/t) and more isolated, narrow high grade intervals (eg. 1m @ 202g/t). At this time mineralization appears to be more vein-hosted than that along the hinge of the Fifteen Mile Stream anticline at Hudson and Egerton MacLean just to the north.

First-pass drilling further east from Plenty on 50m-spaced sections in the hitherto un-drilled gap between Plenty and Egerton MacLean continues to encounter encouraging shallow mineralization though more assay data are awaited to confirm resource potential.

The accompanying cross sections and drilling progress plan can be viewed here: http://files.newswire.ca/1485/atla0123.pdf

Assay results are tabulated below:

True width of the mineralization varies according to the dip of the host stratigraphy and declination of the relevant drill hole. For intersections quoted above true width averages approximately 90% of the down-hole width.

Nature of the mineralization:

Mineralization at Egerton MacLean and Hudson 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 overturned (generally steeply north dipping). All holes are therefore declined to the south. Highest grades so far encountered occur within the hinge zone of the anticline. Mineralization at Plenty is tabular in overall disposition and is thought to be hosted in a deeper, up-faulted southern limb of the Fifteen Mile Stream anticline.  Free gold is commonly observed, and in association with pyrrhotite and arsenopyrite.

Technical Disclosure

At Fifteen Mile Stream all assays by default are 50g charge fire assays of 1kg pulverized sub-sample split from -2mm crushed parent of whole 1m NQ core, with 1-in-10 duplicate assays of the same pulp, and 1-in-10 assays of a second 1kg pulverized sub-sample split from the same crushed parent. Where otherwise noted (^) assays are 50g charge fire assays of 1kg pulverized sub-sample split from -2mm crushed parent of sawn half 1m NQ core, with 1-in-10 duplicate assays of the same pulp. Standards and blind blanks are routinely inserted. 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, blind blanks and duplicate 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.

Further updates will be provided in due course and as new results come to hand.

Forward-looking statements and information can generally be identified by the use of forward-looking terminology such as "may", "will", "expect", "intend", "estimate", "anticipate", "believe", "continue", "plans" or similar terminology. Forward-looking statements and information are not historical facts, are made as of the date of this press release, and include, but are not limited to, statements regarding discussions of future plans, guidance, projections, objectives, estimates and forecasts and statements as to management's expectations with respect to, among other things, the activities contemplated in this news release and the timing and receipt of requisite regulatory, and shareholder approvals in respect thereof. Forward-looking statements in this news release include, without limitation, statements related to proposed exploration and development programs, grade and tonnage of material and resource estimates. These forward looking statements involve numerous risks and uncertainties and actual results may vary. Important factors that may cause actual results to vary include without limitation, the timing and receipt of certain approvals, changes in commodity and power prices, changes in interest and currency exchange rates, risks inherent in exploration estimates and results, timing and success, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources), changes in development or mining plans due to changes in logistical, technical or other factors, unanticipated operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications, cost escalation, unavailability of materials, equipment and third party contractors, delays in the receipt of government approvals, industrial disturbances or other job action, and unanticipated events related to health, safety and environmental matters), political risk, social unrest, and changes in general economic conditions or conditions in the financial markets. In making the forward-looking statements in this press release, the Company has applied several material assumptions, including without limitation, the assumptions that: (1) market fundamentals will result in sustained gold demand and prices; (2) the receipt of any necessary approvals and consents in connection with the development of any properties; (3) the availability of financing on suitable terms for the development, construction and continued operation of any mineral properties; and (4) sustained commodity prices such that any properties put into operation remain economically viable. Information concerning mineral reserve and mineral resource estimates also may be considered forward-looking statements, as such information constitutes a prediction of what mineralization might be found to be present if and when a project is actually developed. Certain of the risks and assumptions are described in more detail in the Company's audited financial statements and MD&A for the year ended December 31, 2016 and for the quarter ended September 30, 2017 on the SEDAR website at www.sedar.com.
