Atlantic Gold Corporation (TSX-V: AGB) is pleased to provide an update of results for its resource extension drilling program at 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. The Cochrane Hill deposit is a fairly predictable and continuous tabular body dipping about 70o to the north with an average true width of approximately 20 to 25m. Holes were drilled on 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).
Particularly notable from the results of the Phase 3 drill program is a robust zone of mineralization over at least a 300m strike length (at approximately Section 3050E to 3350E) below the current pit design and about 180m vertically below surface. Mineralized intervals within this zone have a combined down-hole width per drill hole averaging 30m (true width of about 22m) and a weighted average grade of 2.75g/t Au. This zone was interpreted to be open at depth and to the east. It is also interpreted to have the potential to add high value ounces to further expand the current in-pit resource and potentially result in deepening of the relatively shallow pit designed in the January 2018 Pre-Feasibility Study which has a maximum vertical depth of 175m (See News Release dated January 29, 2018).
Recent drilling, totaling 16,242m in 70 holes, was designed to test potential extensions to defined resources. This was completed over a 475m strike length between Sections 2975E – 3450E. Initial assay results were included in previous news releases (See the Company’s announcements on December 5, 2018 and January 21, 2019). The results for additional holes are included herein (Table 1) and shown on the attached cross-sections. The final drill results are expected shortly and will be released when received.
As previously reported, mineralization typical of Cochrane Hill has been observed in most drill holes. The host rocks are moderately silicified greywacke and argillite protoliths metamorphosed to upper amphibolite facies, with frequent layer-parallel quartz veining. Gold mineralization, including frequently visible gold specks, is associated with pyrrhotite and arsenopyrite.
Assay results received to date indicate significant mineralization with average true widths of 15 to 20m, being intersected at depth beneath previous drilling: 75 to 100m below the previous drilling in the western area (between Sections 2975E to 3100E); at depths of 100 to 125m below the previous drilling in the central zone (between Sections 3050E to 3350E); and, at depths of 50 to 75 m below the previous drilling in the eastern area (between Sections 3375E to 3450E).
Generally, gold assays are distributed evenly across the mineralized zones. However, as in the case of drill hole CH-18-317, several intersections do include single metre assays with elevated gold values (CH 18-317 includes a 1m assay of 466g/t Au within a broader zone of 11m averaging 43.65g/t Au). These higher-grade assays are frequently associated with visible gold that occurs on the margins of bedding parallel quartz veins within the argillite host rock.
For reporting purposes, individual assays greater than 20.0g/t Au that are included in the averages shown are separately identified in Table 1. No top cut has been applied to these assays in determining the reported average value for the mineralized intersection.
Geological interpretation of the data collected in the current program, including recent assay results, is progressing well and will result in a better understanding of the geological controls on grade distribution. This will 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 plunge of the mineralization.
Mineralization remains open to depth on all sections drilled.

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.
All assays reported are 50g charge fire assays of 1kg pulverized sub-sample split from -2mm of crushed parent of sawn half 1m NQ core, with 1-in-10 duplicate assays of the same pulp. Certified standards prepared by a third-party laboratory and blind blanks are routinely inserted. Sample preparation and assaying are conducted at the Sudbury and Vancouver laboratories of ALS Canada Ltd, an entity having no other relationship with the Company. ALS employs a standard routine of duplicate and check assays and reference standards. Standards, blind blanks, and duplicate assay results are within an acceptable range of tolerance. The Company completes a monthly review of QAQC on all assay results which is reviewed by the Qualified Person. Core recovery is estimated for each meter and averages 96%.
