Including 391 g/t Au Over 2.4 Metres in Triple Lynx
TORONTO, Oct. 07, 2020 (GLOBE NEWSWIRE) — 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.
Drilling is currently focused on the Lynx deposit. Osisko Chief Executive Officer John Burzynski commented: “Windfall continues to grow in scale with impressive results flowing in from the Lynx deposit. Today’s new intersections are all from outside the published resource area and include 15 intercepts with uncut average grades of over one oz/t. The ongoing expansion drilling continues to show the incredible upside growth potential of our deposit.”
The table below shows intercepts located outside the February 2020 mineral resource estimate wireframes (
see Osisko news release
dated
February 19, 2020
). These intercepts either expand the resource wireframes or are located in a defined zone/corridor but not yet correlated to a specific wireframe. Significant new analytical results are presented below and include 110 intercepts in 43 drill holes and 24 wedges.
Selected high-grade intercepts from the new results include:
391 g/t Au over 2.4 metres
,
70 metres toward surface from wireframe Lynx_361, in OSK-W-20-2133-W2;
142 g/t Au over 2.3 metres
in OSK-W-20-2307;
86.0 g/t Au over 2.1 metres
in WST-20-0341A;
73.8 g/t Au over 2.0 metres
in WST-20-0470;
54.4 g/t Au over 4.8 metres
in OSK-W-20-2252-W2; and
49.8 g/t Au over 2.2 metres
in OSK-W-20-2292. Maps showing hole locations and full analytical results are available at

Lynx Zone
Mineralization occurs as grey to translucent quartz-carbonate-pyrite-tourmaline veins and pyrite replacement zones and stockworks. The vein-type 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.
Caribou Zone
Mineralization 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.
F-Zone
Mineralization is hosted in sheared andesites with carbonate replacement or quartz veining and occurs as quartz ± ankerite veinlets or in shear zones as replacement, characterised by trace to 10% pyrite with local visible gold. Alteration is dominated by sericite-fuchsite-tourmaline-pyrite.
Bobcat
Mineralization 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.
Mallard
Mineralization is hosted in sheared mafic volcanics with felsic porphyritic intrusions and occurs as veins associated with sericite-pyrite ± silica ± chlorite alteration and contains pyrite ranging from trace to 30% and local visible gold.

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 3.0 g/t Au diluted over core lengths of at least 2.0 metres. All NQ core assays reported 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, Thunder Bay, Ontario, Sudbury, Ontario or Vancouver, British Colombia, or (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 an Aqua Regia-ICP-AES method at ALS Laboratories. Drill program design, Quality

About the Windfall Gold Deposit
The Windfall gold deposit is located between Val-d’Or and Chibougamau i
n
Eeyou Istchee James Bay
,
Québec, Canada. The mineral resource defined by Osisko, as disclosed in
the
news release
dated February 19, 2020
and supported by
the technical report entitled “An updated mineral resource estimate for the Windfall Lake Project, Located in the Abitibi Greenstone Belt, Urban Township, Eeyou Istchee James Bay, Québec, Canada” and dated April 3, 2020 (with an effective date of January 3, 2020)
,
and assuming a cut-off grade of 3.5 g/t, comprises 4,127,000 tonnes at 9.1 g/t Au (1,20
6
,000 ounces) in the indicated mineral resource category and 14,532,000 tonnes at 8.40 g/t Au (3,93

,000 ounces) in the inferred mineral resource category. The key assumptions, parameters and methods used to estimate the mineral resource estimate
disclosed
in the February 19,2020 news
release
are
further described in the full technical report
prepared by Micon International Limited (“Micon”) and BBA Inc (“BBA”)
,
in accordance with NI 43-101
available on SEDAR (www.sedar.com) under the Corporation’s issuer profile. 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

zones:
Lynx,
Main Zone,
and
Underdog
.
