11/05/2018

TORONTO, Nov. 05, 2018 (GLOBE NEWSWIRE) --  Alamos Gold Inc. (TSX:AGI; NYSE:AGI) (“Alamos” or the “Company”) today reported new results from surface and underground exploration drilling at the Island Gold Mine from the second half of 2018. Ongoing drilling continues to extend high-grade gold mineralization along-strike and down-plunge from existing Mineral Reserves and Resources across all three main areas of focus: the Main Extension, the Eastern Extension, and the Western Extension. All reported drill widths are true width of the mineralized zones, unless otherwise stated.

  • Main Extension: best surface directional drilling intersection to date (MH13) extending high-grade gold mineralization 60 metres (“m”) east of the nearest intersection. High-grade mineralization now extends nearly 1,000 m east of current mine workings and remains open to the east and down-plunge. New highlights include:
    • 118.58 g/t Au (39.99 g/t cut) over 6.66 m;
    • 21.50 g/t Au (13.70 g/t cut) over 7.80 m; and
    • 31.70 g/t Au (14.51 g/t cut) over 3.81 m.
       
  • Western Extension: high-grade mineralization extended laterally and down-plunge from existing Inferred Mineral Resources. New highlights include:
    • 78.26 g/t Au (67.74 g/t cut) over 2.29 m; and
    • 19.69 g/t Au (19.69 g/t cut) over 2.79 m.
       
  • Eastern Extension: high-grade mineralization extended below and east of existing Inferred and Indicated Mineral Resources and remains open down-plunge. New highlights include:
    • 46.13 g/t Au (44.17 g/t cut) over 2.83 m; and
    • 13.72 g/t Au (13.72 g/t cut) over 7.60 m.

Note: Drillhole composite intervals reported as “cut” may include higher grade samples which have been cut to 225 g/t Au, 100 g/t Au, or 80g/t Au depending on the zone.  Refer to drill hole composite interval summary tables in this release for more information.

“Island Gold continues to impress. In less than a year since we acquired the mine, we’ve seen a 17% increase in Mineral Reserve grades and significant growth in Mineral Reserves and Resources across all categories. Ongoing exploration success across all three extensions of the ore body, including the best surface directional hole drilled to date, demonstrate strong potential for this to continue,” said John A. McCluskey, President and Chief Executive Officer.

2018 Drilling Program – Island Gold Mine

The focus of the 2018 exploration drilling program is to expand the down-plunge and lateral extensions of the Island Gold deposit with the objective of adding new near mine Mineral Resources.  Drilling continues to be 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 (Figure 1).

Year-to-date drilling has been successful in extending high grade gold mineralization across all three areas resulting in significant growth in both Mineral Reserves and Resources as detailed in the mid-year 2018 update (see press release dated September 5, 2018). Since the acquisition of Island Gold in November 2017, Mineral Reserves have increased 28%, or 207,000 ounces, net of mining depletion, and Mineral Reserve grades have increase 17% to 10.69 g/t Au. Measured and Indicated Mineral Resources have also increased 142%, or 130,000 ounces, and Inferred Mineral Resources have increased 18%, or 184,000 ounces.

A total of 102,500 m of drilling in 556 holes was completed during the first three quarters of 2018, including 37,100 m since the mid-year Mineral Reserve and Resource update. Year-to-date drilling has included 37,200 m of surface directional exploration drilling, 2,700 m of regional exploration drilling and 22,800 m of underground exploration drilling. New highlight intercepts since the mid-year Mineral Reserve and Resource update can be found in Figures 1 to 4 and Tables 1 to 3 at the end of this release.

A further 42,900 m of drilling has been budgeted for the remainder of 2018 with the primary 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 in the second half of 2018 is either too broadly spaced to define Inferred Mineral Resources or focused on regional targets.      

2018 Drilling Program – Island Gold Mine

Main Extension

As detailed in the mid-year 2018 Mineral Reserve and Resource update, a total of 390,000 ounces of Inferred Mineral Resources were added within the Main Extension area. The bulk of the increase was down-plunge from existing mine workings where gold mineralization has been extended nearly 1 kilometre. Exploration drilling continues to target the lateral and down-plunge continuation of gold mineralization below existing Mineral Reserves and outside of the Inferred Mineral Resources reported in the mid-year Mineral Reserve and Resource update. Drilling since the June 30, 2018 update has been successful in further extending gold mineralization with a drill hole spacing ranging from 75 to 100 m (Figure 2). Highlights from the new drill results include (Table 1):

  • 118.58 g/t Au (39.99 g/t cut) over 6.66 m (MH13);
  • 21.50 g/t Au (13.70 g/t cut) over 7.80 m (MH12-2);
  • 31.70 g/t Au (14.51 g/t cut) over 3.81 m (MH9-12);
  • 9.67 g/t Au (9.67 g/t cut) over 4.60 m (MH10-10); and
  • 15.08 g/t Au (15.08 g/t cut) over 2.66 m (MH12-1).

This east-plunging high-grade ore shoot remains open both laterally and down-plunge. Drill holes MH12-1 and MH12-2 are of particular interest because the intersections confirm that gold mineralization extends vertically below a currently known Inferred Mineral Resource block containing 372,600 ounces grading 10.22 g/t Au. 

Hole MH13 is also significant in that it returned the best intersection to date from the surface directional drilling program at 118.58 g/t Au (39.99 g/t cut) over 6.66 m. It also confirms extension of the high-grade mineralization to the east with the nearest previously drilled intersection located 60 m to the west.

The ongoing exploration program is focused on further extending high-grade mineralization with the objective of defining additional Mineral Resources. Four diamond drill rigs are active in the Main Extension target area.

Western Extension

Surface drilling in the Western Extension area (Figure 3) was successful in adding 30,000 ounces of Inferred Mineral Resources as reported in the mid-year Mineral Reserve and Resource update with only two holes completed during the first half of the year. Drilling completed since then has continued to extend high-grade mineralization laterally and down-plunge from existing Inferred Mineral Resources.  

Highlights from the new drill results include (Table 1):

  • 78.26 g/t Au (67.74 g/t cut) over 2.29 m (MH7-5);
  • 19.69 g/t Au (19.69 g/t cut) over 2.79 m (MH5-7); and
  • 13.11 g/t Au (13.11 g/t cut) over 2.44 m (MH4-8);

Holes MH5-7 and MH7-5 confirmed that gold mineralization is present between two previously defined Inferred Mineral Resource blocks. The Company has two drill rigs focused on the Western Extension area using 75 to 100 m spaced step-out drilling with the objective of expanding the high-grade mineralization where it remains open both laterally and down-plunge.

Eastern Extension

An objective of the 2018 underground exploration drilling program is to expand the high-grade zone defined from exploration drifts established at the eastern extent of the Island Gold Mine underground infrastructure (Figure 4). Drilling during the first half of the year was successful in adding 77,000 ounces of Indicated Mineral Resources. Since then, drilling from the 620 exploration drift has continued to intersect high-grade mineralization at depth and to the east.

Highlights from the new results include (Table 2):

  • 46.13 g/t Au (44.17 g/t cut) over 2.83 m (620-605-06); and
  • 13.72 g/t Au (13.72 g/t cut) over 7.60 m (620-605-04).

Hole 620-605-06 is the eastern most hole drilled at depth from the 620-level. It intersected high-grade gold values (44.17 g/t Au cut over 2.83 m) between existing Mineral Resource blocks in the Eastern portion of the Island Gold Mine (between the 340 and 840 levels) and previously reported high grade intersections from surface drill holes drilled further to the east, (Figure 4), which include:

  • 17.85 g/t Au (14.25 g/t cut) over 2.18m (GD-620-01);
  • 57.43 g/t Au (25.37 g/t cut) over 4.37 m (GD-630-01);
  • 18.03 g/t Au (14.16 g/t cut) over 11.53m (GD-640-05);
  • 15.20 g/t Au (8.16 g/t cut) over 2.06 m (GD-640-04); and
  • 43.26 g/t Au (11.72 g/t cut) over 2.13m (GD-640-05-5).

Drilling will continue to test this area for the balance of the year from underground drill bays established on the 620-level exploration drift. In addition, directional drilling from surface is also planned in the Eastern Extension area between 850 and 1150 m vertical depth to further explore this area which cannot be drilled from existing underground exploration drifts.

Underground Delineation Drilling

Underground delineation drilling is also being carried out from the 620 and 840 levels with the focus on converting Inferred Mineral Resources to Indicated Mineral Resources.

New highlight drill intercepts include (Table 3):

  • 84.02 g/t Au (28.71 g/t cut) over 2.61 m (620-574-51);
  • 23.53 g/t Au (23.53 g/t cut) over 2.79 m (840-542-02);
  • 17.20 g/t Au (17.20 g/t cut) over 2.60 m (840-542-09);
  • 16.46 g/t Au (16.46 g/t cut) over 2.52 m (840-542-13); and
  • 16.05 g/t Au (16.05 g/t cut) over 4.76 m (840-542-22).

The results from the infill definition drilling within existing Inferred Mineral Resource blocks confirm the continuity of the high-grade gold mineralization and are expected to support the conversion of the Mineral Resources in these areas.

Other Zones

The 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 Zones which constitutes the main production horizons at the Island Gold mine.  Highlights of new intersections in parallel zones and zones in which the lateral continuity is not yet established (“Unknown”) include (reported composite intervals are core lengths):

  • 127.16 g/t Au (73.66 g/t cut) over 3.10 m (620-598-18);
  • 34.25 g/t Au (18.06 g/t cut) over 3.71 m (620-598-10);
  • 11.88 g/t Au (10.84 g/t cut) over 3.78 m (620-598-03);
  • 16.17 g/t Au (15.36 g/t cut) over 2.69 m (620-604-06); and
  • 11.46 g/t Au (11.46 g/t cut) over 3.61 m (620-598-15).

Additional drilling will be required to further evaluate these high-grade intersections and their potential in both the footwall and hanging wall of the main C and E1E Zones.

Surface Regional Exploration Drilling

A 12,000 m regional exploration drill program commenced in September to drill test targets along the Goudreau Deformation Zone to the west of the main Island Gold Mine deposit. Drilling is also planned to test a previous high-grade intercept of 9.71 g/t Au over 5.95 m below the Kremzar gold deposit.

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.

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.

The risks and uncertainties that may  cause actual results to differ materially from Alamos' expectations include, among others, risks related to obtaining the permits required to carry out planned exploration or development work, the actual results of current exploration activities, conclusions of economic and geological evaluations and changes in project parameters as plans continue to be refined, changes to the price of gold, as well as those factors discussed in the section entitled "Risk Factors" in Alamos' Annual Information Form and other disclosures by Alamos and its predecessors available on the SEDAR website at www.sedar.com or on EDGAR at www.sec.gov. Although Alamos has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated or intended.  Readers are cautioned not to put undue reliance on forward-looking statements which are not guarantees of future events, and speak only as of the date made.

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 SEC 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.

Cautionary Notes – Forward Looking Statements

No stock exchange, securities commission or other regulatory authority has approved or disapproved the information contained herein. Certain statements in this website are “forward-looking statements”, including within the meaning of the United States Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact included in this website, including without limitation statements regarding forecast gold production, gold grades, recoveries, waste-to-ore ratios, total cash costs, potential mineralization and reserves, exploration results, and future plans and objectives of Alamos, are forward-looking statements based on forecasts of future operational or financial results, estimates of amounts not yet determinable and assumptions of management that involve various risks and uncertainties. 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.
