Alamos Gold Sees Significant Increase in Mineral Reserves and Resources at Island Gold

09/05/2018

TORONTO, Sept. 05, 2018 (GLOBE NEWSWIRE) -- Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported an updated National Instrument 43-101 compliant Mineral Reserve and Resource estimate for its Island Gold Mine as of June 30, 2018. This incorporates exploration drilling completed during the first half of 2018, the majority of which was released in the May 24, 2018 exploration update. A summary of updated Mineral Reserves and Resources by category as at June 30, 2018 compared to December 31, 2017 is outlined in the table below.

  • Proven and Probable Mineral Reserves increased 129,000 ounces before mining depletion. Net of mining depletion, Mineral Reserves increased 8%, or 72,000 ounces, to 959,000 ounces, (2,790 thousand tonnes (“kt”) grading 10.69 grams per tonne of gold (“g/t Au”)).
  • Mineral Reserve grades increased 5% to 10.69 g/t Au
  • Measured and Indicated Mineral Resources increased 99%, or 110,000 ounces, to 221,000 ounces while grades increased 40% to 8.18 g/t Au (841 kt grading 8.18 g/t Au)
  • Inferred Mineral Resources increased 30%, or 271,000 ounces, to 1,180,000 ounces with grades increasing 5% to 9.99 g/t Au (3,673 kt grading 9.99 g/t Au)
  • Since the acquisition of Island Gold in November 2017, Mineral Reserves and Resources have continued to grow:
    • Proven and Probable Mineral Reserves have increased 365,000 ounces before mining depletion, or 207,000 ounces, net of mining depletion of 158,000 ounces since the start of 2017. Mineral Reserve grades have increased 17% 
    • Measured and Indicated Mineral Resources have increased 142%, or 130,000 ounces
    • Inferred Mineral Resources have increased 18%, or 184,000 ounces 
  • An $18 million exploration budget in 2018 is driving growth.  This Mineral Reserve and Resource update incorporated a total of 65,500 metres (“m”) of drilling completed across 432 holes during the first half of 2018. A further 84,000 m of surface and underground exploration and delineation drilling has been budgeted for the second half of 2018  

“Island Gold continues to grow in both size and quality. In the nine months since we acquired Island Gold, Mineral Reserves and Resources have grown in all categories while Mineral Reserve grades have increased 17%. As 2018 drilling unfolds, we see excellent potential for this growth to continue,” said John A. McCluskey, President and Chief Executive Officer.

2018 Exploration Program

The focus of the 2018 exploration drilling program is on expanding the down-plunge and lateral extensions of the Island Gold deposit with the objective of adding new near mine Mineral Resources.  Drilling is being conducted across three main areas of focus along the two kilometre long Island Gold Main Zone including; the Main Extension; the Eastern Extension; and the Western Extension. The 2018 program has been successful in extending high grade gold mineralization across all three areas with the bulk of the Mineral Resource increase coming in the Main Extension where the majority of the surface exploration drill holes have been concentrated. The exploration program has also been successful in adding to Mineral Reserves within the Eastern Extension as well as in the Main C Zone.

A total of 65,500 m of drilling across 432 holes was completed during the first half of 2018 and incorporated into Mineral Reserves and Resources as of June 30, 2018. This included 22,500 m of surface directional exploration drilling, 16,300 m of underground exploration drilling, 11,100 m of underground delineation drilling and 15,600 m of underground definition drilling. New highlight intercepts that were incorporated into updated Mineral Reserves and Resources can be found in Figures 1 to 4 and Tables 1 to 3 at the end of this release.

A further 84,000 m has been budgeted for the second half of 2018 with the objective of extending high grade mineralization and adding near-mine Mineral Resources across all three areas of focus. A significant portion of the surface exploration drilling planned for the second half of 2018 will be at wider drill spacing than required for inclusion to Inferred Mineral Resources and focused on regional targets.  As such the Company is not expecting the same pace of Mineral Resource growth with the December 31, 2018 update.   

Mineral Reserves

Proven and Probable Mineral Reserves increased by 129,000 ounces, or 72,000 ounces net of mining depletion through the first half of 2018, to 959,000 ounces of gold. Mineral Reserve grades increased 5% to 10.69 g/t Au. Since the acquisition of Island Gold in November 2017, Mineral Reserves have increased 365,000 ounces, or 207,000 ounces net of mining depletion of 158,000 ounces since the start of 2017. Mineral Reserve grades have also increased 17% as the deposit continues to grow in size and quality. Since the end of 2014, mineral reserves have increased by nearly 800,000 ounces, net of mining depletion of nearly 300,000 ounces, while grades have increased nearly 70% from 6.39 g/t Au to 10.69 g/t Au.

Approximately 65% of the 129,000 ounce increase in Mineral Reserves (as of June 30, 2018), prior to mining depletion, came through a combination of underground delineation and exploration drilling in the Main Zone and Eastern Extension. Underground drilling conducted from the 340, 620 and 840 metre level exploration drifts was successful in converting existing Inferred Mineral Resources to higher classifications including Indicated Mineral Resources and Proven and Probable Mineral Reserves. The program was also successful in adding new Indicated and Inferred Mineral Resources (as discussed below).

The remaining growth in Mineral Reserves was driven by an increase in grades within developed ore blocks in the Main C Zone. The higher grades were the result of an increase in the capping factor applied to face samples in development headings in the Main C Zone to 125 g/t Au, from 65 g/t Au.  The increase in the capping factor was supported by a statistical analysis incorporating ongoing channel sampling and positive grade reconciliation of 15% from actual mining results since the end of 2016.

Mineral Resources

Measured and Indicated Mineral Resources (exclusive of Mineral Reserves) nearly doubled to 221,000 ounces while grades increased 40% to 8.18 g/t Au. The majority of the increase was within the Eastern Extension. 

Inferred Mineral Resources increased 30% to 1,180,000 ounces while grades increased 5% to 9.99 g/t Au. This included the addition of 510,000 ounces during the first six months of 2018 prior to mining depletion and the conversion to higher classifications for a net increase of 271,000 ounces.  Inferred Mineral Resources were added in all three areas of focus with the majority coming in the Main Extension where most of the surface exploration drilling has been concentrated.

Mineral Resource additions by area are detailed as follows.

Main Extension (Figure 2)

A total of 390,000 ounces of Inferred Mineral Resources were added within the Main Extension. The bulk of the increase was in an area of focus down-plunge from existing Mineral Reserves where gold mineralization had been extended up to 1.2 kilometres. Exploration drilling in 2017 and through the first half of 2018 has successfully defined a new Inferred Mineral Resource in this area totaling 314,000 ounces and grading 11.20 g/t Au.

This has extended Inferred Mineral Resources a further 500 m and this east-plunging high-grade ore shoot remains open down-plunge. Surface directional drilling in the second half of 2018 will be focused on further extending high-grade mineralization with the objective of defining additional Mineral Resources.

Eastern Extension (Figure 3)

Indicated Mineral Resources increased 77,000 ounces within the Eastern Extension while Inferred Mineral Resources decreased 22,000 ounces reflecting the conversion to higher categories. Through a mix of underground delineation and exploration drilling, new Indicated and Inferred Mineral Resources were defined below existing Mineral Reserves while existing Inferred Mineral Resources were upgraded to higher Resource and Reserve classifications (as noted above). This area remains open at depth and will be an ongoing focus of underground drilling from the 620 level in the second half of 2018. Surface directional drilling is also planned to test this area between a depth of 900 and 1,300 m this fall.

Western Extension (Figure 4)

A total of 30,000 ounces of Inferred Mineral Resources were added in the Western Extension through limited drilling with two holes completed through first half of 2018. Surface directional drilling during the second half of 2018 will be focused on expanding high-grade mineralization which remains open laterally and down-plunge from existing Inferred Mineral Resource blocks.

Approximately 88,000 ounces of the increase in Inferred Mineral Resources came through an increase in the capping factor applied to drilling assays east of the post mineralization dykes (Figure 1). This represents less than 8% of the total Inferred Mineral Resource of 1,180,000 ounces. The majority of Mineral Resources are located east of the dykes and ongoing drilling has been incorporated into a statistical study supporting an increase in the capping factor to 100 g/t Au, from 70 g/t Au.   

A $1,250 per ounce gold price assumption was used in estimating Mineral Reserves and $1,400 per ounce assumption was used for estimating Mineral Resources as of June 30, 2018, both unchanged from 2017. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. With the exception of the above noted change in capping factors in the C and E1E Zones, all other parameters used in estimating Mineral Reserves and Resources as of June 30, 2018 are unchanged from 2017.

Cautionary Note

This news release includes certain statements that constitute forward-looking information within the meaning of applicable securities laws ("Forward-looking Statements"). 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 "expects", is expected", "anticipates", "plans" or “is planned”, “trends”, "estimates", "intends" 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. Forward-looking Statements in this news release include the statements with respect to planned exploration programs, costs and expenditures, changes in Mineral Resources and conversion of Mineral Resources to Proven and Probable Mineral Reserves, 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.

Alamos cautions readers not to place undue reliance on the forward-looking statements in the information and content on this news release as a number of factors could cause actual future results, conditions, actions or events to differ materially from the targets, outlooks, expectations, goals, estimates or intentions expressed in the Forward-looking Statements. These factors include, but are not limited to: risks related to obtaining and maintaining necessary permits, licenses and authorizations required to carry out planned exploration or development work, the actual results of current exploration activities, conclusions of economic and geological evaluations, changes in project parameters as plans continue to be refined and fluctuations the price of gold.

Exploration results that include geophysics, sampling, and drill results on wide spacings may not be indicative of the occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of Mineral Resource. 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.

Additional risk factors and details with respect to risk factors affecting the Company are set out in the Company’s latest Annual Information From and MD&A, each under the heading “Risk Factors”, available on the  SEDAR website at www.sedar.com or on EDGAR at www.sec.gov.

Cautionary Note to U.S. Investors – Mineral Reserve and Resource Estimates

All Mineral Resource and Reserve estimates included in this news release or documents referenced in this news release have been prepared in accordance with Canadian 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. The terms "Mineral Reserve", "Proven Mineral Reserve" and "Probable Mineral Reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. These definitions differ materially from the definitions in the Securities and Exchange Commission Industry Guide 7 ("SEC Industry Guide 7") under the United States Securities Act of 1933, as amended, and the Exchange Act. Under SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are defined in and required to be disclosed by NI 43-101 and the CIM Standards; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the U.S. Securities and Exchange Commission (the "SEC"). Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into Mineral Reserves. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in very limited circumstances. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a Mineral Resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.

Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as “expects” or “does not expect”, “is expected”, “anticipates” or “does not anticipate”, “plans”, “estimates” or “intends”, or stating that certain actions, events or results “may”, “could”, “would”, “might” or “will” be taken, occur or be achieved) are not statements of historical fact and may be “forward-looking statements.” Alamos cautions that forward-looking information involves known and unknown risks, uncertainties and other factors that may cause Alamos' actual results, performance or achievements to be materially different from those expressed or implied by such information, including, but not limited to, gold and silver price volatility; fluctuations in foreign exchange rates and interest rates; the impact of any hedging activities; discrepancies between actual and estimated production, between actual and estimated reserves and resources or between actual and estimated metallurgical recoveries; costs of production; capital expenditure requirements; the costs and timing of construction and development of new deposits; and the success of exploration and permitting activities. In addition, the factors described or referred to in the section entitled “Risk Factors” in both Alamos Gold Inc.’s Annual Information Form for the year ended December 31, 2014 and the Annual Information Form for the year ended December 31, 2014 of AuRico Gold Inc., (each a predecessor to Alamos Gold Inc.), along with each of these entities’ subsequent public filings available on the SEDAR website at www.sedar.com, should be reviewed in conjunction with the information found in this website. Although Alamos has attempted to identify important factors that could cause actual results, performance or achievements to differ materially from those contained in forward-looking information, there can be other factors that cause results, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate or that management’s expectations or estimates of future developments, circumstances or results will materialize. Accordingly, readers should not place undue reliance on forward-looking information.

Note to U.S. Investors

Alamos prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Terms relating to mineral resources in this website are defined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Standards on Mineral Resources and Mineral Reserves. The United States Securities and Exchange Commission (the “SEC”) permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Alamos may use certain terms, such as “measured mineral resources”, “indicated mineral resources”, “inferred mineral resources” and “probable mineral reserves” that the SEC does not recognize (these terms may be used in this website and are included in the public filings of Alamos, which have been filed with the SEC and the securities commissions or similar authorities in Canada).

Cautionary non-GAAP Measures and Additional GAAP Measures

Note that for purposes of this section, GAAP refers to IFRS. The Company believes that investors use certain non-GAAP and additional GAAP measures as indicators to assess gold mining companies. They are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared with GAAP.
Additional GAAP measures that are presented on the face of the Company’s consolidated statements of comprehensive income include “Mine operating costs”, “Earnings from mine operations” and “Earnings from operations”. These measures are intended to provide an indication of the Company’s mine and operating performance. “Cash flow from operating activities before changes in non-cash working capital” is a non-GAAP performance measure that could provide an indication of the Company’s ability to generate cash flows from operations, and is calculated by adding back the change in non-cash working capital to “Cash provided by (used in) operating activities” as presented on the Company’s consolidated statements of cash flows. “Free cash flow” is a non-GAAP performance measure that is calculated as cash flows from operations net of cash flows invested in mineral property, plant and equipment and exploration and evaluation assets as presented on the Company’s consolidated statements of cash flows and that would provide an indication of the Company’s ability to generate cash flows from its mineral projects. Return on Equity is defined as Earnings from Continuing Operations divided by the average Total Equity for the current and previous year. “Mining cost per tonne of ore” and “Cost per tonne of ore” are non-GAAP performance measures that could provide an indication of the mining and processing efficiency and effectiveness of the mine. These measures are calculated by dividing the relevant mining and processing costs and total costs by the tonnes of ore processed in the period. “Cost per tonne of ore” is usually affected by operating efficiencies and waste-to-ore ratios in the period. “Cash operating costs per ounce”, “total cash costs per ounce” and “all-in sustaining costs per ounce” as used in this analysis are non-GAAP terms typically used by gold mining companies to assess the level of gross margin available to the Company by subtracting these costs from the unit price realized during the period. These non-GAAP terms are also used to assess the ability of a mining company to generate cash flow from operations. There may be some variation in the method of computation of these metrics as determined by the Company compared with other mining companies. In this context, “cash operating costs per ounce” reflects the cash operating costs allocated from in-process and dore inventory associated with ounces of gold sold in the period. “Cash operating costs per ounce” may vary from one period to another due to operating efficiencies, waste-to-ore ratios, grade of ore processed and gold recovery rates in the period. “Total cash costs per ounce” includes “cash operating costs per ounce” plus applicable royalties. Cash operating costs per ounce and total cash costs per ounce are exclusive of exploration costs. “All-in sustaining costs per ounce” include total cash costs, exploration, corporate and administrative, share based compensation and sustaining capital costs. Non-GAAP and additional GAAP measures do not have a standardized meaning prescribed under IFRS and therefore may not be comparable to similar measures presented by other companies. For a reconciliation of non-GAAP and GAAP measures, please refer to Alamos’ Managements’ Discussion and Analysis as presented on SEDAR and the Company’s website.
