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 presented
below include 103 intercepts in 46 drill holes (4 from surface, 42
from underground) and 6 wedges. The infill intercepts are located
inside defined mineral resource estimate (“MRE”) blocks (see Osisko
news release dated August 30, 2022). The expansion intercepts are
located outside the MRE blocks and either expand resource
wireframes or are in a defined zone or corridor not yet correlated
to a specific wireframe.
A new Lynx 4 zone announced earlier this year
(see Osisko news release dated March 23, 2022) was included in the
recent MRE as Lynx 4 wireframe 3466. Two expansion holes confirmed
the growth potential of this wireframe with intercepts 56.9
g/t Au over 2.4 metres and 14.0 g/t Au over 2.9
metres, 170 metres and 80 metres below the current MRE
blocks, respectively.
Expansion intercepts extending wireframes
include: 29.1 g/t Au over 5.8 metres, a 231-meter
extension of Triple Lynx wireframe 3155 below the MRE blocks,
203 g/t Au over 5.2 metres, a 33-meter extension
of Triple Lynx wireframe 3120 to the west, and 51.4 g/t Au
over 2.1 meters, a 39-meter extension of Triple Lynx
wireframe 3161 to the east.
Infill results in this release were received
after the June 7, 2022 database closed for use in the recently
released MRE, and were not included. These infill results will be
used in future mine planning.
Osisko Chief Executive Officer John Burzynski
commented: “Our drill program continues to deliver significant
high-grade results. The expansion holes continue to clearly
demonstrate additional potential growth of the resource base at
Windfall. As the focus shifts to engineering and the pending
feasibility study, we are reducing the number of active drills at
site, however we will maintain exploration work on high-potential
expansion areas as well as drilling on key infill areas for mine
planning.”
Select infill high-grade intercepts include:
93.9 g/t Au over 7.6 metres in
WST-22-1040, 127 g/t Au over 5.7 metres in
WST-22-1032; 112 g/t Au over 5.9 metres in
WST-22-1033; 57.0 g/t Au over 9.3 metres in
OSK-W-22-2601-W7; 53.4 g/t Au over 8.2 metres in
WST-22-1026; 214 g/t Au over 2.0 metres in
WST-22-1029; 176 g/t Au over 2.1 metres in
WST-22-1048; 151 g/t Au over 2.2 metres in
WST-22-1068 and 155 g/t Au over 2.0
metres in WST-22-1071A. Maps showing hole
locations and full analytical results are available at

BobcatMineralization most
commonly occurs in gold-bearing quartz-pyrite veins controlled by
northeast trending faults and shears and to a lesser extent in
minor crustiform quartz-tourmaline-ankerite-pyrite veins and pyrite
replacement zones and stockwork. Mineralization is hosted in
sheared mafic volcanics, rhyolites near faults, or at 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.
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 August 30, 2022, will be
further described, including the key assumptions, parameters and
methods used to estimate the mineral resource estimate disclosed in
the August 30, 2022, news release, 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, and assumes a cut-off grade of 3.50 g/t Au, comprises 811,000
tonnes at 11.4 g/t Au (297,000 ounces) in the measured mineral
resource category, 10,250,000 tonnes at 11.4 g/t Au (3,754,000
ounces) in the indicated mineral resource category and 12,287,000
tonnes at 8.4 g/t Au (3,337,000 ounces) in the inferred mineral
resource category. 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 areas:
Lynx, Main, and Underdog. Mineralization is generally comprised of
sub-vertical lenses following intrusive porphyry contacts plunging
to the northeast. The resources are defined from surface to a depth
of 1,600 metres, including the Triple 8 (TP8) zone. The resources
excluding TP8 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.
About Osisko Mining Inc.Osisko
is a mineral exploration company focused on the acquisition,
exploration, and development of precious metal resource properties
in Canada. Osisko holds a 100% interest in the high-grade Windfall
