Osisko Mining Inc. (OSK:TSX. "Osisko" or the "Corporation") is
pleased to provide new analytical results from the ongoing drill
program at its 100% owned Windfall gold project located in the
Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay,
Québec.
Significant new analytical results that have not
been included in the recently released mineral resource estimate
(“MRE”) (see Osisko news release dated January 10, 2022) are
presented below, and include 94 intercepts in 28 drill holes (9
from surface, 19 from underground) and 25 wedges. The infill
intercepts are located inside defined January 2022 MRE blocks. The
expansion intercepts are located outside the January 2022 MRE
blocks and either expand MRE wireframes or are in a defined zone or
corridor but do not yet correlate to a specific MRE wireframe.
Osisko Chief Executive Officer John Burzynski
commented: “Today’s results serve as a reminder that Windfall
continues to grow in size, underscored by some of these new wide
high-grade hits as the deposit opens up in the heart of the Lynx
system. By virtue of the current resource, Windfall is the largest
high-grade million ounce plus deposit ever discovered in Québec,
and it has been steadily moving up the global list of top
high-grade underground gold deposits. There is nothing quite like
Windfall in Canada, or even globally.”
Selected high-grade intercepts include:
482 g/t Au over 5.7 metres and 380 g/t Au
over 3.2 metres in OSK-W-21-1432-W10; 77.6 g/t Au
over 17.3 metres in OSK-W-21-1949-W14; 124 g/t Au
over 8.0 metres in OSK-W-21-2587-W2; 45.8 g/t Au
over 11.0 metres and 143 g/t Au over 3.4
metres in WST-21-0707; 87.9 g/t Au over 3.2
metres in OSK-W-21-2465-W5; 83.0 g/t Au over 3.0
metres in WST-21-0895A, 37.0 g/t Au over 6.4
metres in OSK-W-21-2613 and 28.1 g/t Au over 6.0
metres in OSK-W-21-2644. Maps showing hole locations and
full analytical results are available at www.osiskomining.com.

Caribou ZoneMineralization most
commonly occurs in gold-bearing pyrite stockworks as well as
semi-massive pyrite replacement zones associated with phyllic
alteration (sericite-pyrite ± silica) with sulphides, pyrite
dominated with minor chalcopyrite and sphalerite ranging from trace
to up to 20%, and local visible gold. Mineralization is hosted in
rhyolites or mafic-intermediate volcanics frequently at or near
faults or the contact with felsic porphyritic intrusions.
Lynx ZoneMineralization occurs
as grey to translucent quartz-carbonate-pyrite-tourmaline veins and
pyrite replacement zones and stockworks. Vein-type mineralization
is associated with haloes of pervasive sericite-pyrite ± silica
alteration and contain sulphides (predominantly pyrite with minor
amounts of chalcopyrite, sphalerite, galena, arsenopyrite, and
pyrrhotite) and local visible gold. Replacement mineralization is
associated with strong pervasive silica-sericite-ankerite ±
tourmaline alteration and contains disseminated pyrite from trace
to 80% with local visible gold. Pyrite stockworks can form
envelopes that reach several tens of metres thick. Fuchsite
alteration is common and is spatially constrained to near the
gabbros. Mineralization occurs at or near geological contacts
between felsic porphyritic or fragmental intrusions and the host
rhyolites or gabbros and locally can be hosted along the
gabbro-rhyolite contact.
UnderdogMineralization most
commonly occurs in gold-bearing quartz-pyrite (± tourmaline) veins
and as disseminated, stringer, semi-massive to massive pyrite with
minor sphalerite, chalcopyrite and molybdenite associated with
strong sericite and silica alteration. Mineralization is hosted
along the intrusive contacts of a three-phase composite felsic
porphyritic unit which cross-cuts felsic and mafic volcanic
sequences.
Windfall NorthMineralization is
hosted in sheared andesites and most commonly occurs in
gold-bearing quartz veins with trace to 10% pyrite, traces of
sphalerite and chalcopyrite, and local visible gold. Mineralization
is hosted in a silica-carbonate-sericite alteration envelope and is
constrained within shear zones with pervasive sericite-carbonate ±
fuchsite ± silica alteration.
Zone 27Mineralization most
commonly occurs as replacement-type characterized by 5% to 50%
disseminated, stringer, semi-massive or stockwork pyrite, ptygmatic
tourmaline veins, quartz-tourmaline crustiform veins, local
quartz-carbonate veins, and local visible gold. Mineralization is
associated with moderate to strong sericite, weak to strong silica,
weak chlorite and carbonate and locally weak fuchsite and is hosted
in strongly altered andesites, in or at the contact of the
rhyolite, or along the contacts with felsic porphyritic
intrusions.
F-ZonesMineralization is hosted
in sheared andesites with carbonate replacement or quartz veining
and occurs as quartz ± ankerite veinlets or as replacement type in
shear zones and is characterised by trace to 10% pyrite with local
visible gold. Alteration is dominated by
sericite-fuchsite-tourmaline-pyrite.
Qualified PersonThe scientific
and technical content of this news release has been reviewed,
prepared and approved by Mr. Louis Grenier, M.Sc.A., P.Geo. (OGQ
800), Director of Exploration for Osisko's Windfall gold project,
who is a "qualified person" as defined by National Instrument
43-101 – Standards of Disclosure for Mineral Projects ("NI
43-101").
Quality Control and Reporting
ProtocolsTrue width determination is estimated at 55-80%
of the reported core length interval for the zone. Assays are uncut
except where indicated. Intercepts occur within geological confines
of major zones but have not been correlated to individual vein
domains at this time. Reported intervals include minimum weighted
averages of 3.5 g/t Au diluted over core lengths of at least 2.0
metres. NQ core assays were obtained by either 1-kilogram screen
fire assay or standard 50-gram fire-assaying-AA finish or
gravimetric finish at (i) ALS Laboratories in Val d'Or, Québec,
Vancouver, British Colombia, Lima, Peru or Vientiane, Laos (ii)
Bureau Veritas in Timmins, Ontario. The 1-kilogram screen assay
method is selected by the geologist when samples contain coarse
gold or present a higher percentage of pyrite than surrounding
intervals. Selected samples are also analyzed for multi-elements,
including silver, using a Four Acid Digestion-ICP-MS method at ALS
Laboratories. Drill program design, Quality Assurance/Quality
Control ("QA/QC") and interpretation of results is performed by
qualified persons employing a QA/QC program consistent with NI
43-101 and industry best practices. Standards and blanks are
included with every 20 samples for QA/QC purposes by the
Corporation as well as the lab. Approximately 5% of sample pulps
are sent to secondary laboratories for check assay.
About the Windfall Gold
DepositThe Windfall gold deposit is located between
Val-d'Or and Chibougamau in the Abitibi region of Québec, Canada.
The Mineral Resource Estimate (“MRE“) defined by Osisko, as
disclosed in the news release dated January 10, 2022 and assuming a
cut-off grade of 3.50 g/t Au, comprises 565,000 tonnes at 11.6 g/t
Au (210,000 ounces) in the measured mineral resource category,
8,907,000 tonnes at 10.5 g/t Au (2,994,000 ounces) in the indicated
mineral resource category and 13,035,000 tonnes at 8.6 g/t Au
(3,585,000 ounces) in the inferred mineral resource category. The
key assumptions, parameters and methods used to estimate the
mineral resource estimate disclosed in the January 10, 2022 news
release, certain of which are described in the January 10, 2022
news release, will be further described in the full technical
report being prepared for this updated mineral resource estimate in
accordance with NI 43-101, and will be available on SEDAR
(www.sedar.com) under the Corporation's issuer profile within 45
days from January 10, 2022. The Windfall gold deposit is currently
one of the highest-grade resource-stage gold projects in Canada and
has world-class scale. Mineralization occurs in three principal
zones: Lynx, Main Zone, and Underdog. Mineralization is generally
comprised of sub-vertical zones following intrusive porphyry
contacts plunging to the northeast. The resources are defined from
surface to a depth of 1,600 metres as it now includes the Triple 8
(T8) zone. The resources excluding T8 are defined from surface to a
depth of 1,200 metres. The deposit remains open along strike and at
depth. Mineralization has been identified at surface in some areas
and as deep as 2,625 metres in others with significant potential to
extend mineralization down-plunge and at depth.
