TSX:AGI; NYSE:AGI Alamos or the Company today reported new results from surface and underground exploration drilling at the Island Gold Mine, further extending high-grade gold mineralization in all three areas of focus. All reported drill widths are true width of the mineralized zones, unless otherwise stated. Island East Lower: high-grade mineralization intersected in the 120 metre m gap between Mineral Resources in the middle and lower portion of Island East. All 28 holes drilled to date in this area have intersected the E1E Zone including 17 intersecting ore grade gold mineralization. This continues to confirm the vertical continuity of the E1E Zone over 1.2 kilometres km, between a depth of 300 m and 1,500 m in the eastern part of the deposit. New highlights include: 44.30 gt Au 44.30 gt cut over 2.25 m MH21-04; and 29.05 gt Au 26.67 gt cut over 4.86 m 620-MH2-01. Island East Upper: high-grade mineralization intersected 200 m east of the nearest Mineral Reserves 620-616-07. New highlights include: 18.72 gt Au 16.44 gt cut over 3.64 m 620-616-07; and 21.30 gt Au 15.52 gt cut over 2.24 m 620-616-02. Island Main: high-grade mineralization intersected 150 m east of existing Mineral Reserves at the 840-level 840-566-06 and 80 m east of existing Mineral Reserves at the 1000-level 840-570-02. New highlights include: 52.10 gt Au 22.54 gt cut over 10.31 m 840-566-01; 21.01 gt Au 21.01 gt cut over 4.26 m 840-566-06; and 31.19 gt Au 31.19 gt cut over 2.22 m 840-572-02. Island West: high-grade gold mineralization extended 70 m from the nearest previously reported drillhole MH16-03 152.07 gt Au 35.74 gt cut over 5.01 m. New highlights include: 25.41 gt Au 23.07 gt cut over 5.58 m MH22-04.Note: Drillhole composite intervals reported as cut may include higher grade samples which have been cut to 225 gt Au for Main and Extension 1 areas, and 160 gt Au for Extension 2 Area.Island Gold has seen exceptional growth over the last several years with the deposit doubling in size since we acquired it in 2017. This includes the addition of nearly one million ounces of Mineral Reserves and Resources through our 2019 exploration program to now total 3.7 million ounces. This growth has been incorporated into a Phase III Expansion Study of the operation which we will be releasing the details of later this week, said John A. McCluskey, President and Chief Executive Officer.These new high-grade results from the 2020 program demonstrate both the significant potential for further growth in Mineral Reserves and Resources and upside to a Phase III Expansion of the operation, Mr. McCluskey added.2020 Exploration Drilling Program Island Gold MineExploration activities at Island Gold remain focused on continuing to define new near mine Mineral Resources and building on the success of the 2019 drilling program. Exploration drilling programs at Island Gold were temporarily suspended on March 25, 2020 given the COVID-19 pandemic; however, began ramping back up in May. The underground diamond drilling program restarted in May with four undergound diamond drill rigs currently operating including two focused on underground directional drilling. The surface directional diamond drilling program resumed in early June with three drill rigs currently drilling.A total of 11,886 m of surface directional diamond drilling and 9,169 m of underground exploration diamond drilling has been completed as of June 30, 2020. New highlight intercepts can be found in Figures 1, 2, and 3 and Tables 1 and 2 at the end of this news release.Island East LowerSurface and underground directional drilling continue to extend gold mineralization with drill hole spacing ranging from 50 m to 100 m Figure 2.New highlights from the surface drilling program include E1E-Zone Table 1: 29.05 gt Au 26.67 gt cut over 4.86 m 620-MH2-01; 44.30 gt Au 44.30 gt cut over 2.25 m MH21-04; and 10.98 gt Au 10.98 gt cut over 2.09 m MH23-01.Gold mineralization continues to be intersected within the 120 m gap between the Inferred Mineral Resource blocks in the middle and lower portion of Island East. This includes new drillholes MH21-04 44.30 gt Au 44.30 gt cut over 2.25 m and 620-MH2-01 29.05 gt Au 26.67 gt cut over 4.86 m. All 28 holes drilled to date in this area have intersected the E1E Zone including 17 intersecting ore grade gold mineralization. This continues to confirm the E1E Zone extends vertically over 1.2 km, between a depth of 300 m and 1,500 m in the eastern part of the deposit.Island East UpperUnderground exploration drilling is being conducted from the 620 level exploration drift. Drilling is testing an area to the east of the Mineral Reserve and Resource blocks in the Eastern Area, between 300 m and 1,100 m vertical depths, and above Inferred Mineral Resources in the lower portion of Island East. New highlights from the underground exploraton drilling program in the E1E Zone include Figure 3, Table 2: 18.72 gt Au 16.44 gt cut over 3.64 m 620-616-07; 8.41 gt Au 8.41 gt cut over 6.30 m 620-610-26; 21.30 gt Au 15.52 gt cut over 2.24 m 620-616-02; and 8.15 gt Au 8.15 gt cut over 3.83 m 620-616-04.New drillholes 620-616-07 18.72 gt Au 16.44 gt cut over 3.64 m intersected high-grade mineralization within the E1E zone 200 m east of the nearest Mineral Reserves of Island East.Two surface directional drill rigs and one underground directional diamond drill rig remain active in Island East, focused on further extending high-grade mineralization and defining additional Mineral Resources, including within the gap area between Inferred Resources.Island MainUnderground exploration drilling is being conducted from the 840 level exploration drift. Drilling is testing an area to the east of the Mineral Reserve and Mineral Resource blocks in the extension of the Main Zone, between 700 m and 1,100 m vertical depths, and above Inferred Mineral Resources of the Main Area. New highlights from the underground exploraton drilling program in the E1E Zone include Figure 3, Table 2: 52.10 gt Au 22.54 gt cut over 10.31 m 840-566-01; 21.01 gt Au 21.01 gt cut over 4.26 m 840-566-06; 31.19 gt Au 31.19 gt cut over 2.22 m 840-572-02; and 13.53 gt Au 13.53 gt cut over 2.36 m 840-566-02.Island WestSurface directional drilling in Island West intersected and extended high-grade gold mineralization drillhole MH22-04 70 m from the nearest previously reported drillhole MH16-03 152.07 gt Au 35.74gt cut over 5.01 m.New highlights from the surface drilling program include C-Zone Table 1: 25.41 gt Au 23.07 gt cut over 5.58 m MH22-04.One surface directional drill rig remains active in this area focused on defining new near mine Mineral Resources.Other ZonesThe Island Gold Deposit consists of a number of subparallel mineralized zones, with the majority of Mineral Reserves and Resources being defined in the C Zone and E1E Zone which constitute the main production horizons at the Island Gold mine. Highlights of new intersections from underground and surface exploration drilling of parallel zones and zones in which the lateral continuity is not yet established Unknown Zone include reported composite intervals are core lengths Table 1 and 2: 40.34 gt Au 40.34 gt cut over 2.75 m 620-MH2-01; and 3.90 gt Au 3.90 gt cut over 8.60 m 620-610-26.Qualified PersonsChris Bostwick, FAusIMM, Alamos Golds Vice President, Technical Services, has reviewed and approved the scientific and technical information contained in this news release.
