Alamos Gold Reports Best Intersection from Surface Directional Drilling
Program Further Extending High-Grade Mineralization at Island Gold Mine
Toronto, Ontario (November 5, 2018) – 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 mineral ization 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 ea st 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 M ineral 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 th ree 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 expl oration 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 R esource block
containing 372,600 ounces grading 10.22 g/t Au.
TRADING SYMBOL: TSX: AGI NYSE:AGI

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 R esource blocks. The Company has two drill rig s focused on the
Western Extension area using 75 to 100 m spaced step -out drilling with the ob jective 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
TRADING SYMBOL: TSX: AGI NYSE:AGI
4 | ALAMOS GOLD INC
• 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 block s
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 prog ram 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.

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 c arry out planned exploration or development work, the actual

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.
