Orezone Continues to Intersect High-Grade GOLD from Its Targeted Infill Drilling Programme at Bomboré
OREZONE CONTINUES TO INTERSECT HIGH-GRADE GOLD FROM ITS TARGETED INFILL
DRILLING PROGRAMME AT BOMBORÉ
July 31, 2018 - Orezone Gold Corporation (TSXV:ORE) (“Orezone” or the “Company”) is pleased
to report ongoing results from its targeted shallow infill Reverse Circulation Drilling (“RC”) and
Diamond Core Drilling (“DD”) within the Bomboré mining lease. This programme totalled 196 RC
boreholes (12,193 m) and 3 0 DD boreholes ( 3,756 m) that were drilled during Q2 2018 in the
Maga, P11 and Siga East areas. These new results continue to show the presence and continuity
of discrete higher -grade zones within the mineral reserve pit shells . Several zones have been
drilled since July 2017 (see press releases of November 2 7th and September 12 th, 2017 for
previous results on some of these targets), and these current results continue to reflect the grade
and continuity of each of these zones. It is expected that the improved definition of these discrete
higher-grade zones in the next mineral resource update should have a positive impact on the
mineral inventory within the infill drilling areas when compared to the current resource model
that formed the basis of the recently released Definitive Feasibility Study.
A general location m ap is shown in the attached presentation (link). The results of each target
are discussed below, with highlights presented from north to south across the strike length that
was tested.
A. Maga Area
The 2018 drilling programme targeted four separate zones with higher-than-average gold grades
with the objectives to better define the geometry (strike, dip and plunge) and continuity of the
shallow portion of these zones. The programme was designed to complete th e 25 m by 25 m
definition drilling pattern in the oxide zone, and on three of the four zones, to step down into the
top portion of the sulphide zone. Based on the recent results, further infill and step out definition
drilling are warranted in all four areas, in both the oxidized and sulphide zones.
Footwall Zone (Oxide and sulphide targets)
The recent drilling programme targeted the northern portion of a 2.4 -km reserve pit shell, over
a strike of 450 m where 16 RC holes (1,194 m) and 5 DD holes (731 m) were drilled. In this area,
the Footwall Zone mineralization is hosted in the nose of a mesoscopic tightly folded sequence
of carbonaceous meta -argillite interbedded with metasandstones over a strike length of about
1.2 km. The sequence is oriented N045 and is dipping about 75 degrees to the SSE.

B. P11 Area
The 2018 drilling programme is a follow -up to the 2017 P11 RC drilling programme (see press
release of November 27th, 2017). The 2018 programme was designed to complete the 25 m by
25 m definition drilling pattern in the oxide zone over a strike length of 1.2 km, and to step down
into the top portion of the sulphide zone . The gold mineralization is hosted in a sequence of
meta-sediments, biotite schist (meta -gabbro) and meta -granodiorite. This lithostratigraphic
sequence defines a very tight synformal fold open to the north, with a w est limb oriented N350
and an east limb oriented N360. The lithological contacts, the regional foliation and the
mineralized envelopes are all dipping about 65 degrees to the ENE. The recent drilling
programme consisted of 74 RC holes (4,015 m) and 12 DD holes (1,346 m).

C. Siga East Area
The 2018 drilling programme is a follow-up to the 2017 Siga East RC drilling programme (see press
release of September 12 th, 2017). The 2018 programme was designed to complete the 25 m by
25 m definition drilling pattern in the oxide zone over a strike length of 800 m along the main
Footwall Zone, and to advance the definition of various hanging wall mineralized zones. The gold
mineralization is hosted in a sequence of meta-sediments, biotite schist (meta-gabbro) and meta-
granodiorite. This lithostratigraphic sequence defines a large S -fold with long limbs oriented
N350 and a short limb oriented N360 . The recent drilling programme co nsisted of 71 RC holes
(4,301 m).

Patrick Downey, President and CEO stated, “The encouraging results from the 2017 drill program
and this most recent Q2 2018 drilling program targeting higher-grade zones within the Bomboré
mining lease have further validated our belief that better -than-reserve grade mineralization
exists within the reserve pit shells in specifically targeted areas . We are confident that once
6
properly modelled within planned Resource updates that future mining of these zones could lead
to significantly better gold grades in these area s than the grades currently predicted by the
Company’s mineral reserve model. Furthermore, these most recent drilling results show that
these higher-grade zones may continue into the sulphide resources beneath the oxide pits and
there is potential to add additional higher-grade sulphides similar to that at P17 (see press release
of July 16th, 2018) which could add to the future production profile of Bomboré.”
Sampling, analytical and QAQC protocols
The mineralized intervals are based on a lower cut -off grade (“LCOG”) of 0.45 g pt, a minimal
width of 2 m and up to a maximum of 2 m of dilution being included between samples above the
LCOG. The true width of the mineralization is yet to be determined at Siga East Hanging Wall
zones, and is approximately 90% of the drill length at Maga Footwall and 3653 zones, 95% of the
drill length at Maga Hill, Maga 3645 and P11 zones, and 100% of the dri ll length at Siga East
Footwall zone. The RC drilling samples were divided by Orezone employees using Rotary Sample
Dividers (“RSDs”). A 2-kg split was prepared by SGS Burkina Faso s.a.r.l. at the Bomboré sample
preparation facility and then split by Orezone to 1 kg using RSDs. A 1-kg aliquot was analyzed for
leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle -roll cyanidation using a
LeachWellTM catalyst. The leach residues from all samples with a leach grade in excess of 0.2 gpt
were prepared by BIGS Global Burkina s.a.r.l. and then split by Orezone to 50 g using RSDs. A 50-
g aliquot was analyzed by fire assay at SGS Burkina Faso s.a.r.l. The composite width and grade
include the final leach residue assay results for all of the drill intercepts reported. Orezone
employs a rigorous Quality Control Program (QCP) including a minimum of 10% standards, blanks
and duplicates. A complete list of assay results from the current drilling programme can be found
on the Company’s website at the following link (Drill Results).

“will”, “could”, or “should” occur. Forward-looking statements in this release include statements
regarding, among others; the drill results from the Maga Area (Footwall Zone, Maga Hill Zone, 3653 Zone,
and 3645 Zone), P11 and Siga East (Siga East Footwall Zone and Siga East Hanging Wall Zones) will improve
the definition of discrete higher-grade zones in the next mineral resource updates with a positive impact
on the mineral inventory when compared to the current resource model; additional infill and step out
definition drilling are warranted in the Maga Area; drill results from the 2017 and recent 2018 programs
validate management’s belief that better-than-average grade mineralization exists within the reserve pit
shells in the targeted areas and future mining could lead to better gold grades than those currently
predicted by the Company’s mineral reserve model; and possible extension of these higher-grade zones
into the sulphide resources which may add to the future production profile of Bomboré.
All such forward-looking statements are based on certain assumptions and analyses made by
management in light of their experience and perception of historical trends, current conditions and
expected future developments, as well as other factors management believe are appropriate in the
