Osisko Intersects 140 g/t Au Over 5.0 Metres At Lynx

Posted on January 9, 2018November 8, 2023 by lboivin

(Toronto, January 9, 2018) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. The 800,000 metre drill program combines definition, expansion and exploration drilling in and around the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall).

Significant new analytical results from 90 intercepts in 52 drill holes focused on infill and expansion drilling in the Lynx deposit are presented below. Osisko continues to extend the known Lynx zones of mineralization through the application of the Windfall geological model and as the density of drilling increases.

The main Lynx Corridor has been extended up plunge 250 metres SW from the last drill intercept for a total current strike length of confirmed mineralization over 1,550 metres and remains open.
Lynx HW is showing good continuity and grades towards the NE.
Lynx 4 has been extended 75 metres NE for a total current strike length of 1,350 metres and new infill drillholes continue to demonstrate continuity and robust gold grades between sections 3650E and 4225E.

Highlights from the new results include: 140 g/t Au over 5.0 metres in OSK-W-17-1343; 210 g/t Au over 2.4 metres in OSK-W-17-923; 28.3 g/t Au over 7.7 metres in OSK-W-17-1193; 83.0 g/t Au over 2.0 metres in OSK-W-17-1059; 43.1 g/t Au over 4.4 metres in OSK-W-1343-W2; 48.7 g/t Au over 2.6 metres in OSK-W-17-1104; 43.8 g/t Au over 2.5 metres in OSK-W-17-1242; 22.6 g/t Au over 4.8 metres in OSK-W-17-888; 16.0 g/t Au over 5.5 metres and 22.9 g/t Au over 2.4 metres in OSK-W-17-1177; 29.8 g/t Au over 2.2 metres in OSK-W-17-1085; 14.8 g/t Au over 4.4 metres in OSK-W-1193-W1; 27.9 g/t Au over 2.4 metres in OSK-W-17-1181-W1; and 20.6 g/t Au over 2.2 metres in OSK-17-W-945.

Osisko Intersects 30 g/t Au Over 2.4 Metres At Windfall

Posted on December 5, 2017November 8, 2023 by lboivin

(Toronto, December 5, 2017) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. The 800,000 metre drill program combines definition, expansion and exploration drilling in and around the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall). Significant new analytical results from 52 intercepts in 40 drill holes focused on infill and expansion drilling in the Underdog, Caribou, Zone 27 and Mallard corridors of the Windfall deposit are presented below.

Highlights from the new results include: 30 g/t Au over 2.4 metres, in OSK-W-17-1141; 10.2 g/t Au over 5.4 metres in OSK-W-17-1125, 26.0 g/t Au over 2.2 metres in OSK-W-17-1125-W3 and 5.38 g/t Au over 9.0 metres in OSK-W-17-1186.

Qualified Person
The 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), Project Manager of the Windfall Lake 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 Protocols
True widths determinations are estimated at 65-80% of the reported core length intervals for most of the zones. 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 ALS Laboratories in Val dOr, Québec, Thunder Bay and Sudbury, Ontario or Vancouver, British Colombia or 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 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 Lake Gold Deposit
The Windfall Lake gold deposit is located between Val-dOr and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by the previous operator comprises 2,762,000 tonnes at 8.42 g/t Au (748.000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (sourced from a technical report dated June 10, 2015 entitled “Preliminary Economic Assessment of the Windfall Lake Gold Property, Québec, Canada” with an effective date of April 28, 2015, prepared in accordance with NI 43-101). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1.400 metres long. The deposit is well defined from surface to a depth of 500 metres, and remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization up and down-plunge and at depth.

OSK-G17-388, 391, 395, 401, 403, 405, 407, 409 were drilled as part of a program to test the extension of a mineralized zone bulk sampled in prior work. During a bulk sample program conducted in 2014 – 2015 by the previous property operator, testing focused on a N-NE trending mineralized corridor marked by zones of quartz-iron carbonate breccias. The mineralized corridor was found to dip shallowly to the east. New drilling involved a series of shallow west oriented holes designed to intersect the mineralized corridor at high angles to its strike.

The new results include:

1.34 g/t Au over 22.2 metres in OSK-G17-388
1.24 g/t Au over 20.9 metres in OSK-G17-391
2.01 g/t Au over 21.5 metres and
3.10 g/t Au over 17.0 metres in OSK-G17-395
1.16 g/t Au over 19.8 metres in OSK-G17-401
1.50 g/t Au over 15.0 metres in OSK-G17-403
4.28 g/t Au over 6.9 metres in OSK-G17-405
1.57 g/t Au over 8.9 metres in OSK-G17-409

Previous reported holes (see August 22, 2017 press release) from this program included OSK-G17-386 (1.20 g/t Au over 33.8 metres), OSK-G17-393 (1.12 g/t Au over 59.3 metres) and OSK-G17-398 (1.13 g/t Au over 22.8 metres).

OSK-G17-410, 414, 419, 423, 426 were designed to test the mineralized zone dipping below the Garrcon east bulk sample pit. The east bulk sample pit tested in 2014 – 2015 showed a parallel zone to the west bulk sample pit trending N-NE and comprised mainly of multiple parallel 1-10 cm quartz-iron carbonate veins hosted within metasediment. Similar to the west bulk sample pit, the mineralized corridor has a shallow east dip.

The new results include:

1.16 g/t Au over 8.8 metres in OSK-G17-410
4.96 g/t Au over 13.5 metres in OSK-G17-414
1.44 g/t Au over 10.0 metres and
4.63 g/t Au over 3.5 metres in OSK-G17-419
3.60 g/t Au over 9.0 metres and
4.45 g/t Au over 5.5 metres in OSK-G17-423
6.30 g/t Au over 2.0 metres and
8.14 g/t Au over 2.7 metres in OSK-G17-426

In both bulk sample pits the mineralization is closely associated with the N-NE trending quartz iron carbonate veins, breccias and fractures showing a strong iron carbonate alteration of the host rock. Mineralization consists of pyrite concentrations up to 2% along with local visible gold.

OSK-G17-336 was drilled north west of the Garrcon west bulk sample pit intersecting a fracture zone within metasediment near the collar of the hole, with local visible gold returning 37.1 g/t Au over 1.0 metre.

OSK-G17-402, 380 were infill holes in the Garrcon Zone along section 1200W, drilling across the host metasediment. OSK-G17-380 intersected 2.13 g/t Au over 17.0 metres within a zone of quartz-iron carbonate fracturing showing moderate hematite alteration. OSK-G17-402 intersected two significant mineralized zones including 2.86 g/t Au over 9.8 metres comprised of a broad zone of quartz-iron carbonate veins from 1-5 cm containing 1-2% pyrite, and local visible gold within an iron carbonate alteration halo. A second interval returned 1.71 g/t Au over 10.0 metres within a fractured zone including minor quartz-iron carbonate and disseminated pyrite.

OSK-G17-427 intersected 7.69 g/t Au over 4.5 metres within a broad quartz-iron carbonate breccia within iron carbonate altered metasediment. This zone correlates with historical drill hole GAR-11-70, 25 metres north which intersected 5.65 g/t Au over 3.0 metres and GAR-12-159 located 40 metres south which intersected 8.39 g/t over 2.0 metres. A second mineralized zone within the hole returned 58.1 g/t Au over 1.0 metre within a zone containing quartz-iron carbonate fracturing and pervasive hematite altered metasediment.

OSK-G17-438 was drilled vertically between the two bulk sample pits at Garrcon. The hole intersected the down dip extension of the mineralized zone in the west bulk sample pit averaging 6.12 g/t Au over 6.0 metres. This interval is hosted within iron carbonate altered metasediment containing multiple 1 cm quartz-iron carbonate. A second intercept of the Garrcon deep zone returned 10.6 g/t Au over 3.5 metres.

OSK-G17-407 did not intersect significant mineralization.

Senior Project Manager of the Garrison 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
True widths of the new exploration intercepts reported in this press release have yet to be determined, but are typically 65 – 90% of reported core lengths. Additional work is planned for the immediate area which will enable the true width determination. Assays are uncut except where indicated, and calculated intervals are reported over a minimum length of 2 metres using a lower cutoff of 1.0 g/t Au. All HQ core assays reported were obtained by either whole sample rock metallic screen/fire assay or standard 30 gram fire-assaying with ICP finish at SGS Minerals Services in Cochrane, Ontario or through AAS finish at Bureau Veritas Mineral Laboratories in Timmins, Ontario. The whole sample metallic screen assay method is selected by the geologist when samples contain coarse gold or any samples displaying gold initial fire assay values greater than 4g/t. Drill program design, Quality Assurance/Quality Control and interpretation of results is performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for Quality Assurance/Quality Control purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.

About the Garrison Project
The Garrison Project area is comprised of 214 mineral claims, 25 mining leases, and 87 patent claims encompassing approximately 8,000 hectares. Both Garrcon and Jonpol have resource estimates that are described in a technical report prepared in accordance with NI 43-101, which was completed by a previous operator Northern Gold Mining Inc. (entitled “Technical Report on the Golden Bear Project – Garrison Property: Larder Lake Mining Division, Garrison Township, Ontario, Canada”) dated December 30, 2013, with an effective date of December 30, 2013 (the “Garrison Technical Report”). The Garrison Technical Report was prepared by A.C.A. Howe International Limited for Northern Gold Mining Inc. (a wholly-owned subsidiary of Osisko) and is available on Osiskos website at www.osiskomining.com and on SEDAR under Northern Gold Mining Inc.s issuer profile at www.sedar.com.

Resource estimates were conducted by A.C.A. Howe International Limited according to CIM standards. The Garrcon Zone estimates showed 15.1 million tonnes with an average grade of 1.07 g/t Au (521,000 oz) in measured resources; 14.1 million tonnes averaging 1.16 g/t Au (526,000 oz) in indicated resources; and 1.7 million tonnes averaging 0.72 g/t Au (39,000 oz) in inferred resources. Potential underground resources of 5.1 million tonnes averaging 3.49 g/t Au (577,000 oz) in the inferred category were also outlined. Resources were reported at a cut-off grade of 0.4 g/t Au for open pit extraction and 1.5 g/t in a bulk underground mining scenario using a gold price of US$1,250/oz.

At the Jonpol Zone, resources were estimated as 0.87 million tonnes averaging 5.34 g/t Au (150,000 oz) in the indicated category; and 1.07 million tonnes averaging 5.56 g/t Au (192,000 oz) in inferred resources. Resources were reported at a cut-off grade of 3.0 g/t Au and assume an underground extraction scenario using a gold price of US$1,250/oz.

Readers are cautioned that inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

Garrcon Zone
The Garrcon Zone has a shallow plunge eastward along the footwall of the Destor-Porcupine Fault Zone with the bulk of the resource in the western, more densely drilled area. The zone is exposed at surface and has potential for open pit bulk mining at an estimated overall stripping ratio of 1.8:1. There is potential for additional underground resources below the pit and along the easterly plunge of the zone, which is open for further exploration down dip and along strike.

The Garrcon shaft was sunk in 1935 and 1936 by the Consolidated Mining and Smelting Co. of Canada (“Cominco”) and the Shaft and South Zones were tested for high grade gold mineralization. Cominco drove approximately 1,430 metres of drifts and cross cuts, mining underground veins. Diamond drilling by Cominco and Lac Minerals Ltd. in the mid-to-late 1980s identified broad sections of low grade mineralization. In 2006-2007, ValGold Resources Ltd. conducted additional drilling confirming these zones. From 2009-2013 Northern Gold Mining Inc. conducted 97,000 metres of diamond drilling which delineated the current resource.

In 2014, Northern Gold Mining Inc. was granted a trial mining permit allowing the extraction of up to 150,000 tonnes. Northern Gold Mining Inc. mined 73,534 dry tonnes which was processed at the nearby Holt mill facility recovering 3,516 oz at an average head grade of 1.55 g/t and recovery of 95.9%. The trial production permit remains active.

Jonpol Zone
Jonpol is situated in the Munro Fault Zone, a west striking splay off the north side of the Destor-Porcupine Fault. Hosted in a shear zone tens of metres wide in altered mafic volcanic rocks, the deposit consists of four high grade gold mineralized zones (JP, JD, RP and East) over a strike length of 1.7 kilometers. Gold mineralization is hosted in quartz carbonate veins, in mafic and ultramafic host rocks, and is associated with intense albite and/or sericite alteration and pyrite mineralization.

In 1997, a 49,087 tonne bulk sample was extracted from the central part of the JP zone by Hillsborough Resources Limited with an average grade of 6.7 g/t which produced 9,476 ounces Au. From 1985-2013, over 130,000 metres of drilling was completed on the property by previous operators. Development work on the JP zone included the sinking of a 184 metre shaft as well as development of a ramp to the 150 metre level with mining on six sublevels. The Jonpol infrastructure underwent reclamation in the late 1990s and was closed out in 2001, but the existing ramp and shaft are preserved.

Qualified Person

The 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), Project Manager of the Windfall Lake 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 Protocols

True widths determinations are estimated at 65-80% of the reported core length intervals for most of the zones. 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 ALS Laboratories in Val dOr, Québec, Thunder Bay and Sudbury, Ontario or Vancouver, British Colombia or 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 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 Lake Gold Deposit

The Windfall Lake gold deposit is located between Val-dOr and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by the previous operator comprises 2,762,000 tonnes at 8.42 g/t Au (748.000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (sourced from a technical report dated June 10, 2015 entitled “Preliminary Economic Assessment of the Windfall Lake Gold Property, Québec, Canada” with an effective date of April 28, 2015, prepared in accordance with NI 43-101). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1.400 metres long. The deposit is well defined from surface to a depth of 500 metres, and remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization up and down-plunge and at depth.

The two broad zones are hosted in syenite showing a porphyritic texture and significant fracturing containing specular hematite and pyrite mineralization.

OSK-G17-370 targeted the eastern extension of the main 903 Zone and 903 South Zone along strike. The hole intersected a new shallow mineralized zone along the flow contact between an ultramafic volcanic and mafic volcanic. This horizon contains limited syenite surrounded by a broad quartz carbonate veining over 10 metres and averaging 2.65 g/t Au over 9.1 metres. A second mineralized zone was intersected along the eastern extension of the 903 South Zone horizon characterized by intense quartz and iron carbonate fracturing adjacent to diabase and hosted within ultramafic volcanic. This interval reported a average of 1.33 g/t Au over 12.0 metres.

OSK-G17-371A, 374A and 382 were drilled southwest of the main 903 syenite, targeting a linear magnetic low that may represent a fault offset extension of the main 903 Zone extending west. All three holes intersected a zone of mariposite alteration ranging from 50 to 75 metres in width containing syenite coincident with the magnetic low. Anomalous gold grades were reported from holes 374A and 382. OSK-G17-371A intersected two separate syenite dykes ranging in width from 15 to 40 metres. The first syenite dyke showed a brick red hematite alteration and limited quartz veining which averaged 1.65 g/t Au over 13.0 metres. The second broader syenite contained considerable quartz – iron carbonate veining up to 1 metre in width a long with minor hematite alteration and disseminated pyrite; this interval averaged 2.00 g/t Au over 11.4 metres.

OSK-G17-379, 396, 406 were drilled along section 3000W in the western section of the main 903 Zone. Each of the holes intersected syenite within the 903 Zone. A strong interval of quartz – iron carbonate veining and hematite alteration was found in OSK-G17-396 reporting a shallow intercept averaging 1.03 g/t Au over 16.0 metres. Drilling 55 metres below this intercept hole OSK-G17-406 also intersected syenite containing significant iron – carbonate veining along with a moderate hematite alteration believed to be the extension of the zone found in OSK-G17-396. Within the syenite dykes two mineralized zones averaged 2.44 g/t Au over 8.0 metres and 1.43 g/t Au over 15.1 metres. Below this interval (110 metres) OSK-G17-379 intersected syenite dykes hosted within mariposite schist. An interval within the dyke assayed 5.37 g/t Au over 2.0 metres also coincident with veining and hematite alteration.

OSK-G17-400, 412 were drilled along section 2950W within the main 903 Zone. Drill hole OSK-G17-400 was drilled north of the main syenite body and did not intersected any significant dykes; drilling into the footwall metasediment the hole intersected a 5 cm quartz-iron carbonate vein and surrounding fracturing that averaged 6.44 g/t Au over 2.0 metres. Testing 120 metres below OSK-G17-400,OSK-G17-412 intersected a broad zone of syenite along the main trend of the 903 Zone. Within the syenite was quartz-iron carbonate veining with moderate hematite alteration of the syenite as well as along fractures and showing disseminated pyrite within the syenite; this interval averaged 1.62 g/t Au over 16.1 metres. This hole also intersected the footwall metasediment within which a broad chlorite alteration zone containing quartz and iron carbonate veining from 2-40 cm in width and showing disseminated pyrite within the metasediment, averaging 5.18 g/t Au over 17.0 metres. A second interval within the metasediment showing only limited quartz-iron carbonate fracturing to 1 cm width averaged 10.4 g/t Au over 2.0 metres.

OSK-G17-408 was drilled along the eastern strike extension of the 903 Zone targeting the up dip extension of syenite intersected in OSK-G17-332 (1.09 g/t Au over 17.0 metres, March 15, 2017). The hole intersected syenite 35 metres up dip of OSK-G17-332. The syenite contained moderate quartz – iron carbonate veins from 10 to 20 cm in width along with hematite alteration and disseminated pyrite. This shallow interval averaged 1.37 g/t Au over 30.2 metres.

OSK-G17-415, 420 were drilled along section 2800W in the central 903 Zone. OSK-G17-415 was drilled 50 metres down dip of OSK-G17-335 (1.57g/t Au over 10.0 metres and 1.49 g/t Au over 9.0 metres, March 15, 2017). The hole successfully intersected the main 903 syenite dyke at a vertical depth of 185 metres but reported limited mineralization. The upper part of hole OSK-G17-415 intersected the southern 903 Zone within highly altered metasediment containing sericite and iron carbonate alteration. Very fine disseminated pyrite along with 1-2 cm quartz – iron carbonate veins contained within the metasediment averaged 2.84 g/t Au over 7.1 metres. OSK-G17-420 was drilled 50 metres up dip from OSK-G17-335, intersecting a 75 metre wide syenite body. Within the upper contact of the syenite there is considerable strong hematite alteration along with limited quartz – iron carbonate veining and 2-3% coarse disseminated pyrite; this interval returned 7.14 g/t Au over 12.7 metres.

OSK-G17-345, -404, -411 did not intersect significant mineralization.

Quality Control
True widths of the new exploration intercepts reported in this press release have yet to be determined, but are typically 65 – 90% of reported core lengths. Additional drilling is planned for the immediate area which will enable the true width determination. Assays are uncut except where indicated, and calculated intervals are reported over a minimum length of 2 metres using a lower cutoff of 1.0 g/t Au. All HQ core assays reported were obtained by either whole sample rock metallic screen/fire assay or standard 30 gram fire-assaying with ICP finish at SGS Minerals Services in Cochrane, Ontario. The whole sample metallic screen assay method is selected by the geologist when samples contain coarse gold or any samples displaying gold initial fire assay values greater than 4g/t. Drill program design, Quality Assurance/Quality Control and interpretation of results is performed by qualified persons employing a Quality Assurance/Quality Control program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for Quality Assurance/Quality Control purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assays.
