TORONTO, Feb. 13, 2024 (GLOBE NEWSWIRE) -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported new results from underground exploration drilling at the Island Gold Mine. Underground exploration drilling continues to extend high-grade gold mineralization across the Island Gold Deposit within the main E1E and C-Zones, as well as several hanging wall and footwall structures in proximity to existing underground infrastructure. These results are expected to contribute to another increase in high-grade Mineral Reserves and Resources at Island Gold to be outlined in the 2023 year-end update to be released later this month.
Island Gold Main zone exploration highlights: high-grade mineralization extended outside of Mineral Reserves and Resources in the E1E and C-Zones. These zones are the main structures which host the majority of currently defined Mineral Reserves and Resources at Island Gold. New highlights include1:
- Island East (E1E-Zone)
- 34.48 g/t Au (34.48 g/t cut) over 2.82 m (840-632-49);
- 20.85 g/t Au (20.85 g/t cut) over 2.41 m (1040-619-20);
- 19.22 g/t Au (19.22 g/t cut) over 2.05 m (945-624-34); and

Island Gold Hanging wall and Footwall exploration highlights: high-grade gold mineralization intersected within several recently defined hanging wall and footwall zones across the main Island Gold Deposit. These zones represent a significant opportunity to add near mine Mineral Reserves and Resources which would be low-cost to develop and produce given their proximity to existing infrastructure. This includes the NS1 Zone which was discovered early in 2023 and was being developed and mined by the end of the year. New highlights include1:
- Island West Hanging Wall Zones
B Zone
- 29.33 g/t Au (23.89 g/t cut) over 6.93 m (790-479-34);
- 40.36 g/t Au (40.36 g/t cut) over 3.91 m (790-479-40);
- 65.23 g/t Au (24.36 g/t cut) over 2.28 m (900-506-09);
NS1 Zone: currently defined over a North-South strike of approximately 70 m and vertical continuity of over 450 m, and remains open up and down dip
- 23.34 g/t Au (12.56 g/t cut) over 4.03 m (900-506-10);
- 17.30 g/t Au (8.61 g/t cut) over 3.41 m (900-506-11A);
- 12.33 g/t Au (12.33 g/t cut) over 3.96 m (900-506-07); and
- 10.46 g/t Au (10.46 g/t cut) over 4.17 m (900-506-08).
- Island East Footwall Zones
E1D1 Zone
- 67.08 g/t Au (13.21 g/t cut) over 2.56 m (1040-619-22);
- 50.10 g/t Au (12.67 g/t cut) over 2.35 m (1040-619-31); and
- 14.78 g/t Au (14.39 g/t cut) over 2.17 m (1040-619-20).
E1D Zone
- 228.50 g/t Au (70.63 g/t cut) over 2.79 m (945-624-31A); and
- 52.31 g/t Au (15.13 g/t cut) over 2.06 m (945-624-32).
Other Hanging Wall and Footwall intersections: drilling continues to intersect high-grade mineralization in proximity to existing underground infrastructure in yet to be defined zones. These are part of more than 2,000 intersections above 3 g/t Au outside of existing Mineral Reserves and Resources in the hanging wall and footwall, highlighting the opportunity for significant near-mine additions as ongoing drilling further defines these areas. New highlights include2:
Footwall
- 1389.65 g/t Au over 2.90 m (620-595-02);
- 39.42 g/t Au over 2.45 m (840-632-49);
- 25.85 g/t Au over 3.65 m (840-632-41);
- 18.71 g/t Au over 3.45 m (1015-640-06); and
- 16.05 g/t Au over 2.75 m (840-632-41).
Hanging Wall
- 103.37 g/t Au over 2.90 m (900-506-13);
- 52.65 g/t Au over 2.15 m (900-506-06); and
- 17.33 g/t Au over 2.70 m (900-506-13).
1 All reported composite intervals are calculated true width of the mineralized zones, unless otherwise stated. Drillhole composite intervals reported as “cut” may include higher grade samples which have been cut to: Island West (C-zone) and Island Main @ 225 g/t Au; Island Main and East (E1E Zone) @ 185 g/t Au; E1D Zone @ 100 g/t Au; B Zone, E1D1 zone and NS1 @ 90 g/t Au.
2 All reported composite intervals are core length, true width is unknown at this time, and gold grades are reported as uncut).
"Our transition to underground exploration drilling from surface directional drilling has been successful across a number of fronts. Drilling continues to extend high-grade mineralization across the two kilometre long lateral extent of the main Island Gold deposit, as well as within a number of new and expanding zones in the hanging wall and footwall. These results within the main Island Gold structure and a growing number of hanging wall and footwall zones are expected to drive another increase in combined Mineral Reserves and Resources at Island Gold with the year-end update to be released later this month. This is expected to mark the eighth consecutive year of Mineral Reserve and Resource growth over which time the deposit has more than tripled in size to well over five million ounces of gold,” said John A. McCluskey, President and Chief Executive Officer.
“These expected high-grade additions are all in proximity to our existing underground infrastructure such that they will be low-cost to develop and provide increasing operational flexibility as we expand the operation. With the main deposit open laterally and down-plunge, and more than 2,000 intersections of significant gold mineralization outside of existing Reserves and Resources in the hanging wall and footwall, we expect Island Gold’s tremendous track record of growth to continue,” Mr. McCluskey added.
New highlight intercepts can be found in Tables 1 and 2, and in Figures 1 and 2 at the end of this news release.
2023 Exploration Drilling Program – Island Gold
During 2023, 157 holes totaling 39,110 metres (“m”) were completed as part of the underground exploration program, and 155 holes totaling 31,636 m as part of the underground delineation drilling program. To support the underground program, a total of 404 m of underground exploration drift development was completed in 2023 on the 850, 945, and 1025 levels. Additionally, 5,131 m of surface drilling was completed in three holes. The regional surface drilling program, focused on the Pine-Breccia and Cline Edwards Plowman targets, was completed in the third quarter of 2023 and included 42 holes over 8,432 m.
2024 Exploration Drilling Program
A total of $19 million is budgeted for exploration at Island Gold in 2024, up from $14 million in 2023, with both a larger near mine and regional exploration program planned for the year. The 2024 exploration program will follow up on a successful 2023 program with high-grade gold mineralization extended laterally to the West and East as well as within multiple structures within the hanging wall and footwall.
Consistent with the 2023 program, the majority of the 2024 mine exploration program will be comprised of underground drilling with 41,000 m planned. The focus will be the definition of new Mineral Reserves and Resources in proximity to existing production horizons and infrastructure, as well as the conversion of the large existing Mineral Resource base to Mineral Reserves. This includes drilling across the strike extent of the main Island Gold Deposit (E1E and C-Zones), as well as within a growing number of newly defined hanging-wall and footwall zones. To support the underground exploration drilling program, 460 m of underground exploration drift development is planned to extend drill platforms on the 850, 945, and 1025-levels.
Additionally, 12,500 m of surface exploration drilling has been budgeted targeting high potential areas within the Island West, Main and East ore shoots, the up-plunge extension of the Island West ore shoot, and evaluating the potential for high-grade mineralized hanging wall structures near surface.
The regional exploration program has also been expanded to 10,000 m. The 2024 program will follow up on high-grade mineralization intersected at the Pine-Breccia and 88-60 targets, located 4 kilometres (“km”) and 7 km, respectively, from the Island Gold Mine. Drilling will also be completed in proximity to the past-producing Cline and Edwards mines, as well as at the Island Gold North Shear target. A comprehensive data compilation project will also commence across the broader 40,000 hectare Manitou land package that was acquired in 2023 in support of future exploration targeting.
Island West
Underground Exploration Drilling
Underground drilling has further extended high-grade gold mineralization along strike, 150 m to the west, and up plunge of existing Mineral Reserves and Resources in the middle portion of Island West. Drilling is being conducted from the 490-level and the 790-level exploration drifts, between vertical depths of 400 m and 1,100 m.
New highlights include (Figure 1, Table 1):
C-Zone
- 106.04 g/t Au (48.86 g/t cut) over 2.38 m (490-456-13); and
- 19.56 g/t Au (19.56 g/t cut) over 3.81 m (790-479-40).
Island West Hanging Wall Zones
In addition to testing the C-Zone, underground exploration drilling continued to target and expand on previous drilling that intersected high-grade gold mineralization in sub-parallel and perpendicular structures in the hanging wall from the 490, 790, and 900-levels.
NS1 Hanging Wall Zone
The NS1 zone is a north-striking structure with a high-angle orientation relative to the C-Zone. After being discovered early in 2023, the first stopes were mined from the NS1 zone during the second half 2023 highlighting the near-term opportunities within these hanging wall and footwall zones. Ongoing drill testing and five exploration sills have been completed from the 750, 770, 790, 810, and 850-levels which have demonstrated excellent continuity, over an average strike of 40 m to the south on these levels, and over 100 m vertically. Additional drilling from the 490, 580, 770, and 900 levels has now expanded the NS1 zone over a vertical extent of 450 m, from the 400 level to the 995 level, and defined an average strike of 70 m.
In addition to contributing to near-term production, an initial Mineral Reserve and Resource will be declared within the NS1 zone in the year-end 2023 update. The zone remains open up and down dip and will be an ongoing focus of drilling in 2024. In addition, other north-striking high-angle structures have been identified across the deposit, which will be evaluated further as underground exploration drilling advances.
New highlights from the Island West Hanging Wall zones include (Table 1):
B Zone
- 29.33 g/t Au (23.89 g/t cut) over 6.93 m (790-479-34);
- 40.36 g/t Au (40.36 g/t cut) over 3.91 m (790-479-40);
- 65.23 g/t Au (24.36 g/t cut) over 2.28 m (900-506-09);
NS1 Zone:
- 23.34 g/t Au (12.56 g/t cut) over 4.03 m (900-506-10);
- 17.30 g/t Au (8.61 g/t cut) over 3.41 m (900-506-11A);
- 12.33 g/t Au (12.33 g/t cut) over 3.96 m (900-506-07); and
- 10.46 g/t Au (10.46 g/t cut) over 4.17 m (900-506-08).
Island East
Underground Exploration Drilling
Underground drilling from the 840 and 945-level exploration drifts, as well as the 1040 ramp continues to extend high-grade gold mineralization along strike to the east of Mineral Reserves and Resources in the middle portion of Island East (between vertical depths of 700 m and 1,300 m).
New highlights in the E1E-Zone include (Figure 1, Table 1):
- 34.48 g/t Au (34.48 g/t cut) over 2.82 m (840-632-49);
- 20.85 g/t Au (20.85 g/t cut) over 2.41 m (1040-619-20);
- 19.22 g/t Au (19.22 g/t cut) over 2.05 m (945-624-34);
- 16.13 g/t Au (16.13 g/t cut) over 2.45 m (840-530-09);
- 16.99 g/t Au (16.99 g/t cut) over 2.05 m (840-632-47); and
- 14.76 g/t Au (12.66 g/t cut) over 2.06 m (840-632-45).
Island East Footwall Zones
In addition to testing the E1E-Zone, underground exploration drilling continued to target and expand on previous drilling that intersected high-grade gold mineralization in structures in the footwall from the 945 and 1040-levels. This additional drilling has been successful in establishing continuity and extending high-grade gold mineralization within multiple structures referred to as the E1D1 and E1D zones, located 10 m and 30 m from the E1E-Zone, respectively.
New highlights from the Island East Footwall zones include (Table 1):
E1D1 Zone
- 67.08 g/t Au (13.21 g/t cut) over 2.56 m (1040-619-22);
- 50.10 g/t Au (12.67 g/t cut) over 2.35 m (1040-619-31);
- 14.78 g/t Au (14.39 g/t cut) over 2.17 m (1040-619-20); and
- 14.45 g/t Au (14.45 g/t cut) over 2.05 m (1040-619-13).
E1D Zone
- 228.50 g/t Au (70.63 g/t cut) over 2.79 m (945-624-31A); and
- 52.31 g/t Au (15.13 g/t cut) over 2.06 m (945-624-32).
As with the hanging wall and footwall zones in Island West, these footwall zones in Island East highlight the potential to add high-grade Mineral Reserves and Resources in proximity of existing production horizons and infrastructure which would be low-cost to develop and mine.
Other Zones
The majority of Island Gold’s Mineral Reserves and Resources and main production horizons are hosted in the C/E1E structure. The Island Gold Deposit also consists of a growing number of sub-parallel and high-angle mineralized structures outside of the main C/E1E-Zone. As underground development advances, these sub-parallel hanging wall and footwall structures can be targeted and defined with step-out drilling from underground drill platforms.
These zones and other targets within the hanging wall and footwall represent significant opportunities to define additional high-grade Mineral Reserves and Resources outside of the main C/E1E-Zone in proximity to existing underground infrastructure. These additions would enhance the ounce per vertical metre profile and provide multiple mining horizons from the same lateral development levels.
The following are highlights of new hanging wall and footwall intersections from underground exploration drilling where the geometry and continuity are not yet established (“Unknown Zone”). These are part of more than 2,000 intersections above 3 g/t Au within recently defined and yet to be defined zones in the hanging wall and footwall. These intersections are outside of existing Mineral Reserves and Resources, highlighting the opportunity for significant near-mine additions as ongoing drilling further defines these areas.
New highlights include (reported composite intervals are uncut and as core length, as true width is unknown at this time) (Table 1):
Footwall intersections:
- 1389.65 g/t Au over 2.90 m (620-595-02);
- 39.42 g/t Au over 2.45 m (840-632-49);
- 25.85 g/t Au over 3.65 m (840-632-41);
- 18.71 g/t Au over 3.45 m (1015-640-06); and
- 16.05 g/t Au over 2.75 m (840-632-41).
Hanging wall intersections:
- 103.37 g/t over 2.90 m (900-506-13);
- 52.65 g/t Au over 2.15 m (900-506-06); and
- 17.33 g/t Au over 2.70 m (900-506-13).

Quality Assurance and Quality Control
Alamos Gold maintains an internal Quality Assurance / Quality Control (QA/QC) program at the Island Gold Mine to ensure sampling and analysis of all exploration work is conducted in accordance with best practices.
Access to the Island Gold Mine is controlled by security personnel. Drill core is logged and sampled at core logging facilities within the mine site under the supervision of a Qualified Geologist. A geologist marks the individual samples for analysis, and sample intervals, sample numbers, standards and blanks are entered into the database. The core is cut in half using an electric core saw equipped with a diamond tipped blade. One half of the core is placed into a plastic sample bag and sealed with zip ties in preparation for shipment. The other half of the core is returned to the core box and retained for future reference. The samples are placed in large heavy-duty nylon reinforced Fabrene bags, which are identified and sealed before being placed on pallets. The core samples are picked up at the mine site and mine samples are delivered to AGAT and Actlabs laboratories, and regional samples are delivered to ALS laboratory, all located in Thunder Bay, Ontario.
Gold is analyzed by a 50 grams fire assay with an Atomic Absorption (AA) finish. Mine samples greater than 10.0 g/t Au, and regional samples greater than 5.0 g/t Au are re-analyzed using gravimetric finish methods. AGAT, Actlabs and ALS are certified laboratories and have internal quality control (“QC”) programs that include insertion of reagent blanks, reference materials, and pulp duplicates.
The Corporation inserts QC samples (blanks and reference materials) at regular intervals to monitor laboratory performance. Cross check assays are completed on a regular basis in a secondary accredited laboratory. The Island Gold Mine QA/QC procedures are more completely described in the August 29, 2022 Technical Report filed on SEDAR+ ( www.sedarplus.ca).

Note to U.S. Investors – Mineral Reserve and Resource Estimates
Unless otherwise indicated, all Mineral Resource and Mineral Reserve estimates included in this news release have been prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Mining disclosure in the United States was previously required to comply with SEC Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Exchange Act of 1934, as amended. The U.S. Securities and Exchange Commission (the “SEC”) has adopted final rules, to replace SEC Industry Guide 7 with new mining disclosure rules under sub-part 1300 of Regulation S-K of the U.S. Securities Act (“Regulation S-K 1300”) which became mandatory for U.S. reporting companies beginning with the first fiscal year commencing on or after January 1, 2021. Under Regulation S-K 1300, the SEC now recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” to be substantially similar to international standards.
Investors are cautioned that while the above terms are “substantially similar” to CIM Definitions, there are differences in the definitions under Regulation S-K 1300 and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the mineral reserve or mineral resource estimates under the standards adopted under Regulation S-K 1300. U.S. investors are also cautioned that while the SEC recognizes “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under Regulation S-K 1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable.
