VANCOUVER, Feb. 21, 2019 /CNW/ - Atlantic Gold Corporation (TSX-V: AGB) ("Atlantic" or the "Company") is pleased to provide final drill results for its Resource Extension drill programs which were completed late in 2018 at the Cochrane Hill Gold Deposit ("Cochrane Hill") and Fifteen Mile Stream Gold Deposit ("Fifteen Mile Stream").

The Phase 3 Resource Expansion Drill Programs at the Fifteen Mile Stream and Cochrane Hill Gold Deposits between September 2017 and February 2018 successfully identified additional gold mineralization immediately adjacent to previously defined mineral resources at both locations. Compilation and analysis of the results of these programs determined that in the Egerton-MacLean Zone at Fifteen Mile Stream and at Cochrane Hill there remained potential to extend known mineralization.

Drill programs totaling 11,385m in 69 drill holes and 16,242m in 70 drill holes were completed at Fifteen Mile Stream and Cochrane Hill, respectively, between mid-September and mid-December 2018 to test interpreted extensions to the known resources. Partial results for these drill campaigns were announced in earlier press releases (See News Releases dated December 5, 2018; January 21, 2019; and, February 6, 2019). Final drill results for these drill programs are contained in this release, tabulated on Tables 1 and 2 and presented in the linked plans and sections.

This news release completes reporting of results from the 2018 Phase 3 drill program. All deposits remain open along strike and/or at depth; a review program is currently underway to identify, rate and rank targets across Atlantic Gold's project portfolio to prioritize exploration targets for further drill-testing in 2019.

COCHRANE HILL GOLD DEPOSIT

The recently completed diamond drilling at Cochrane Hill continues to confirm extensions to the mineralization defined by the Phase 3 Resource Definition drill program, completed earlier in 2018 and supports other recently published results from the program.

Cochrane Hill is located approximately 80km northeast of the Company's central processing facility at the Moose River Consolidated Gold Mine. Cochrane Hill's current Measured and Indicated Mineral Resources stand at 10.66 million tonnes at 1.16 g/t Au for 398,000 oz. at a 0.35g/t Au cut-off grade. Inferred Mineral Resources amount to 1.63 million tonnes at 1.32 g/t Au for 69,000 oz. at a 0.35g/t Au cut-off grade (see the Company's announcement on January 29, 2018)1.

The Phase 3 Resource Expansion drilling program at Cochrane Hill was completed in January 2018, with 44 holes for 6,900m having been drilled. Holes were drilled on a nominal 25m x 20m centers to test for resource extensions of this mineralization eastwards and at depth to the northeast. The results of this program were announced in prior news releases; however, these results were not included in the resource estimation referred to above (See Company announcements on March 15, 2018, and April 4, 2018).

Results of the Phase 3 drill program defined a robust zone of mineralization below the current pit design to a depth of approximately 180m vertically below surface. This zone was interpreted to be open at depth and to the east, with a potential to expand the current in-pit resource and the relatively shallow pit designed in the January 2018 Pre-Feasibility Study. (See News Release dated January 29, 2018).

The Resource Extension drilling program, completed in November-December 2018, was designed to test this potential target area. Initial assay results were included in previous news releases (See the Company's announcements on December 5, 2018; January 21, 2019; and, February 6, 2019); final drill results are shown in Table 1, below.

Host rocks at Cochrane Hill are moderately silicified greywacke and argillite protoliths metamorphosed to upper amphibolite facies, with frequent layer-parallel quartz veining. The deposit is a continuous tabular body, dipping 70o to the north, and is interpreted to be within the overturned sheared southern limb of a tight, near isoclinal anticline that plunges gently to the west.

The mineralized zone has an average true thickness of 15-20m and lies between two laterally continuous argillite horizons. Gold mineralization, including frequently visible free gold specks, is associated with pyrrhotite and arsenopyrite. Generally, gold assays are distributed evenly across the mineralized zone; however, several intersections do include single metre assays with elevated gold values that are frequently associated with visible gold on the margins of quartz veins within the host rock.

Following the recent drill program, geological interpretation has identified a robust mineralized core zone approximately 325m along strike (Section 2975E – 3300E). This core zone is thicker than average, at 20-25m true width, with steep easterly plunge, as shown by grade distribution on the long section. Higher grades within this zone are spatially related to greater abundance of quartz veining; there is an indication that this zone becomes wider down dip, and it is open at depth. To the east of this zone, smaller, parallel higher-grade shoots have been identified and are also open down plunge.

Cochrane Hill Long Section (CNW Group/Atlantic Gold Corporation)

Interpretation and modelling of the mineralized zone continues to assist in targeting further down-dip and strike extensions of the deposit, particularly to the east where initial observations indicate that drilling may have overshot the target due to changes in the interpreted plunge of the mineralization. The steep easterly plunge of higher-grade mineralization fits with both the current deposit scale and the regional scale structural interpretation. The increased understanding of the structural controls on the deposit will lead to potential additional drill targets, including but not limited to down plunge extension of the core zone and eastern ore shoots, and more regionally to other targets in the vicinity of Cochrane Hill.

1The Mineral Resource estimate for the Cochrane Hill Gold Deposit is quoted at a cut-off grade of 0.35g/t. It has an effective date of July 20, 2017 and was prepared as part of a technical report entitled (Moose River Consolidated Project, Nova Scotia Canada, NI 43-101 Technical Report on Moose River Consolidated Phase 1 and Phase 2 Expansion), in accordance with NI 43-101 by Mr. Neil Schofield, a principal of FSSI (Australia) Pty Ltd, released on March 15, 2018, on SEDAR.

FIFTEEN MILE STREAM GOLD DEPOSIT

The Fifteen Mile Stream Gold Deposit is located approximately 57km northeast of the central processing facility at the Moose River Consolidated Gold Mine. 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 a 0.35g/t Au cut-off grade. Inferred Mineral Resources amount to 6.64 million tonnes at 1.12 g/t Au for 240,000 oz at a 0.35g/t Au cut-off grade (see Company announcement dated January 29, 2018)2.

The Phase 3 Resource Expansion diamond drilling program at Fifteen Mile Stream was completed at the end of February 2018 with a total of 221 holes and 24,325m drilled. Results of this program were announced in earlier news releases (see Company announcement dated March 15, 2018).

At Fifteen Mile Stream, mineralization comprises disseminated gold within argillites and greywackes of the Moose River Formation, as well as coarse gold within bedding-parallel quartz veins. Gold mineralization is concentrated in three zones:  Egerton-MacLean, Hudson, and Plenty (see location plan).

The Hudson and Egerton-MacLean Zones lie within the hinge and northern limb of the Fifteen Mile Stream Anticline. Secondary folding and fault repetition have led to a larger zone of mineralization in the Egerton-MacLean Zone than in the Hudson Zone. The Plenty Zone is a tabular body within the overturned southern limb of the Fifteen Mile Stream Anticline. The anticline that hosts the Egerton-MacLean Zone plunges to the east, with the northern limb dipping moderately at 70° to the north, and the southern limb overturned and dipping steeply northwards. All drill holes are drilled to the south.

Phase 3 drilling reported early in 2018 indicated that mineralization was open both down dip to the north and down plunge to the east. The Resource Extension program completed between September – December 2018, comprised of 11,385m in 69 drill holes, was designed to test this potential target.

Resource Extension drill results previously announced further defined disseminated mineralization in the eastern Egerton-MacLean Zone in the core of the anticline and on the northern limb of the anticline in the central and western Egerton-MacLean Zone. High-grade, vein-hosted gold was also intersected in deeper units along the anticline hinge zone (See News Release dated December 5, 2018).

The final drillholes completed in the Resource Extension program were located along the northern and eastern end of the Egerton-Maclean zone, targeting deeper, down dip and easterly plunging mineralization. Results from these holes, presented in Table 2, below, include broad zones of lower grade mineralization, essentially defining the northern and easterly limit to the Egerton-Maclean Zone.
