TORONTO, Feb. 02, 2023 (GLOBE NEWSWIRE) -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported new results from ongoing surface exploration drilling at Puerto Del Aire (“PDA”), further extending high-grade gold mineralization outside of Mineral Reserves and Resources. PDA is a higher-grade underground deposit, adjacent to the main Mulatos pit, and is comprised of five zones including PDA1, PDA2, Gap, Victor and Estrella. All reported composite widths are estimated true width of the mineralized zones.
Puerto Del Aire: high-grade gold mineralization extended within 200 metre (“m”) gap between Mineral Reserves and Resources at PDA1 and PDA2 as drilling continues to close the gap between the two zones. This includes the best hole drilled in the 2022 program and one of the best holes drilled to date at PDA (22MUL077). New highlights include:
PDA1 and PDA2:
33.40 g/t Au (11.48 g/t cut) over 25.95 m (22MUL077);
67.58 g/t Au (32.11 g/t cut) over 3.25 m (22MUL064);
18.33 g/t (15.83 g/t cut) Au over 6.20 m (22MUL085);
75.50 g/t Au (40.00 g/t cut) over 1.50 m (22MUL063);
36.50 g/t Au over 2.35 m (22MUL086);
60.20 g/t Au (40.00 g/t cut) over 1.40 m (22MUL065);
11.16 g/t Au over 6.75 m (22MUL090); and
6.73 g/t Au over 9.00 m (22MUL071).
Note: Drillhole composite gold grades reported as “cut” may include higher grade samples which have been cut to 40 g/t Au.
“We expect these results to drive a significant increase in Mineral Reserves at PDA in our year end update to be released later this month. With the deposit open in multiple directions, and an expanded exploration program planned at Mulatos in 2023, we expect this growth to continue. These results will be incorporated into an updated development plan to be released in the second half of 2023. Given PDA’s higher grades and proximity to the Mulatos pit, we see excellent potential for this to be another low-cost, high-return project further extending the mine life at Mulatos. Over the past 18 years, Mulatos has produced 2.5 million ounces of gold while maintaining a similar Reserve life today as it had in 2005. Given our ongoing exploration success at PDA, and the potential within the District, we expect this trend to continue,” said John A. McCluskey, President and Chief Executive Officer.
New highlight intercepts can be found in Table 1, and in Figures 3 and 4 at the end of this news release.
Puerto Del Aire
PDA is a higher-grade underground deposit located adjacent to the main Mulatos pit, and is comprised of five mineralized zones – PDA1, PDA2, Gap, Victor, and Estrella (Figure 2). In February 2022, Alamos announced an initial Mineral Reserve at PDA totalling 428,000 ounces (2.85 million tonnes “Mt” grading 4.67 g/t Au) as part of the December 31st, 2021 Mineral Reserve and Mineral Resource update. In addition to the Mineral Reserve, Measured and Indicated Mineral Resources totalled 124,000 ounces (0.77 Mt grading 5.05 g/t Au). Mineral Reserves were determined based on Mineral Resource estimations that were completed within gold mineralization wireframes that were finalized in July 2020 and April 2021, based on detailed geological modelling (see “Mineralization Wireframe” in Figure 2).
PDA1 and PDA2
Surface exploration drilling continues to extend high-grade mineralization beyond existing Mineral Reserves and Resources across multiple mineralized zones within PDA. This includes a number of intercepts well above the current Mineral Reserve grade within the 200 m gap between Mineral Reserves and Resources in PDA1 and PDA2, including 22MUL077, one of the best holes ever drilled at PDA at 33.40 g/t Au (11.48 g/t cut) over 25.95 m. These results along with previously released drilling completed since April 2021 (see press release dated November 15, 2022) are expected to drive a significant increase in Mineral Reserves at PDA in the year end 2022 update to be released later in February 2023. This updated Mineral Reserve and Resource will be used as the basis for a new development plan for PDA which is expected to be completed in the second half of 2023.
Since April 2021, 92 drill holes totalling 27,117 metres have been completed at PDA which were not included in the 2021 year end Mineral Reserve and Resource. All drill holes were completed with the objective of expanding mineralization as either step outs from existing Mineral Resources, or targeting areas within the previously interpreted mineralization wireframe that did not contain a Mineral Resource due to limited drilling.
The exploration program at Mulatos is expected to ramp up significantly in 2023 with $17 million budgeted, more than double the 2022 budget. This includes $4 million budgeted at PDA with 16,000 m of drilling focused on expanding higher-grade Mineral Reserves and Mineral Resources with the deposit open in multiple directions.
PDA is expected to be mined from underground and accessed from a ramp and development drifts off the main Mulatos pit. This will greatly reduce the development needed to access the deposit. The Company expects to expand and upgrade the existing mill at Mulatos to process the higher-grade ore from PDA.

Quality Assurance and Quality Control
Alamos Gold maintains an internal Quality Assurance / Quality Control (QA/QC) program at Mulatos to ensure sampling and analysis of all exploration work is conducted in accordance with best practices.
Access to the Mulatos Property is controlled by security personnel. Drill core is logged and sampled at the core logging facility within the mine site under the supervision of a Qualified Geologist. A geologist marks the individual samples for analysis, and sample intervals, based on lithology and alteration, 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 micropore sample bag and sealed with a cable tie 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 micropore bags, which are identified and sealed before being dispatched. The core samples are picked up at the mine site and delivered to Bureau Veritas Commodities Canada Ltd. laboratory in Hermosillo, Mexico.
Gold is analyzed by 30 grams Lead Collection Fire Assay Fusion (FA) that ends with an Atomic Absorption Spectroscopy finish (AAS). Samples greater than 5.0 g/t Au are re-analyzed with an FA process followed by a gravimetric finish (GRAV). Bureau Veritas is an ISO/IEC 17025 accredited laboratory and has internal quality control (“QC”) programs that include insertion of reagent blanks, reference materials, and pulp duplicates that are in line with normal requirements, as well as participating on yearly proficiency tests to evaluate lab performance.
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.

All statements in this news release other than statements of historical fact, which address events, results, outcomes or developments that Alamos expects to occur are forward-looking statements. Forward-looking statements are generally, but not always, identified by the use of forward-looking terminology such as “continue”, "expect", "plan", "estimate", “target”, “budget”, “prospective” or “potential” or variations of such words and phrases and similar expressions or statements that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved or the negative connotation of such terms.
Such statements in this news release include, without limitation, statements with respect to: planned exploration programs and focuses, potential drilling results and related expectations, costs and expenditures, project economics, gold price assumptions, potential mineralization, projected ore grades, Mineral Reserves and Resources, expected mine life and potential extensions of mine life at Mulatos, expected increases in the value of operations, planned release of an updated development plan and timing thereof, intended method of accessing and mining the deposit at Puerto Del Aire and the intended method of processing any ore from the deposit at Puerto Del Aire, and other information that is based on forecasts and projections of future operational, geological or financial results, estimates of amounts not yet determinable and assumptions of management.
A Mineral Resource that is classified as "inferred" or "indicated" has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an "Indicated Mineral Resource" or "Inferred Mineral Resource" will ever be upgraded to a higher category of Mineral Resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into Proven and Probable Mineral Reserves.
Alamos cautions that forward-looking statements are necessarily based upon several factors and assumptions that, while considered reasonable by management at the time of making such statements, are inherently subject to significant business, economic, technical, legal, political and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements, and undue reliance should not be placed on such statements and information.
These factors and assumptions include, but are not limited to: the actual results of current exploration activities; conclusions of economic and geological evaluations; changes in project parameters as plans continue to be refined; any ongoing or new impacts of the COVID-19 pandemic (or any other new epidemic or pandemic) on operations and the broader market, including the nature and duration of any ongoing or new regulatory responses; state and federal orders or mandates (including with respect to mining operations generally or auxiliary businesses or services required for the Company’s operations) in Mexico; changes in national and local government legislation, controls or regulations; failure to comply with environmental and health and safety laws and regulations; labour and contractor availability (and being able to secure the same on favourable terms); ability to sell or deliver gold doré bars; disruptions in the maintenance or provision of required infrastructure and information technology systems; fluctuations in the price of gold or certain other commodities such as, diesel fuel, natural gas, and electricity; operating or technical difficulties in connection with mining or development activities, including geotechnical challenges and changes to production estimates (which assume accuracy of projected ore grade, mining rates, recovery timing and recovery rate estimates and may be impacted by unscheduled maintenance); changes in foreign exchange rates (particularly the Canadian dollar, U.S. dollar, and Mexican peso); the impact of inflation; employee and community relations; litigation and administrative proceedings; disruptions affecting operations; availability of and increased costs associated with mining inputs and labour; delays in the development or updating of mine and/or development plans; changes that may be required to the intended method of accessing and mining the deposit at Puerto Del Aire and changes related to the intended method of processing any ore from the deposit at Puerto Del Aire; inherent risks and hazards associated with mining and mineral processing including environmental hazards, industrial accidents, unusual or unexpected formations, pressures and cave-ins; the risk that the Company’s mines may not perform as planned; uncertainty with the Company's ability to secure additional capital to execute its business plans; the speculative nature of mineral exploration and development, risks in obtaining and maintaining necessary licenses, permits and authorizations, contests over title to properties; expropriation or nationalization of property; political or economic developments in Canada or Mexico and other jurisdictions in which the Company may carry on business in the future; increased costs and risks related to the potential impact of climate change; the costs and timing of construction and development of new deposits; risk of loss due to sabotage, protests and other civil disturbances; the impact of global liquidity and credit availability and the values of assets and liabilities based on projected future cash flows; and business opportunities that may be pursued by the Company.

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.
