OSISKO TO BEGIN DRILLING “DEEP DISCOVERY 1” AT WINDFALL

Posted on April 30, 2019November 8, 2023 by Yannick Fradette

Longest Diamond Drill Hole in Canada Planned to Hunt for Windfall Source

(Toronto, April 30, 2019) Osisko Mining Inc. (OSK:TSX “Osisko” or the “Corporation”) is pleased to announce it will begin drilling what is planned to be Canada’s longest diamond drill hole, “Deep Discovery 1”, in May at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

Deep Discovery 1 is designed to test the intrusion associated geological model for the Windfall deposit, following on the success of the previous deep drill holes (please see Osisko’s Triple 8 discovery news releases dated July 11, 2018, August 7, 2018, and September 13, 2018). The drill hole will investigate the potential depth extensions of known mineralized zones (Underdog and Triple 8) on its path to the principal exploration target: the interpreted outer shell and centre of a possible porphyry intrusion at depths of approximately 3,000 metres to 3,500 metres from surface.

Major Drilling Group International Inc. of Moncton, New Brunswick will drill the hole using their EF-100 deep drill rig, which is currently preparing to mobilize to Windfall from Red Lake. Once collared, it is anticipated the drill hole will take approximately six months to complete.

Osisko is also conducting preliminary work on the potential use of high-definition seismic techniques to identify deep gold-bearing structures and potentially directly detect certain styles of mineralization in and around the Windfall and Lynx deposits. HiSeis Pty Ltd. (“HeiSeis”), from Perth, Australia, have been contracted by Osisko to evaluate the applicability of their data acquisition equipment and innovative data processing algorithms to the Windfall system. The potential use of seismic techniques will compliment the successful IP survey which outlined new deep drill targets and the chargeability signature of the Triple 8 Zone (please see Osisko news release March 26, 2019). HiSeis was involved in the discovery of the Zodiac Zone at Northern Star Resources Jundee gold deposit. The Zodiac Zone target was defined using HeiSeis 3D seismic.

Osisko President and Chief Executive Officer John Burzynski commented: “We are very excited to continue ground-breaking exploration in and around Windfall. Deep Discovery 1 presents an opportunity to test the deep porphyry intrusion model that we believe is the driver of the Windfall system. The potential application of seismic techniques would be an innovative addition to the successful recent definition of new targets we achieved through the use of downhole geophysics. We remain convinced that as we continue deep exploration, Windfall will grow to join the ranks of world class high-grade and long-life underground mines in the Canadian Archean.”

About the Windfall Lake Gold Deposit

The Windfall gold deposit is located between Val-d’Or and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by Osisko, as disclosed in the Windfall Lake Technical Report (as defined below) and November 27, 2018 Lynx resource update, comprises 2,874,000 tonnes at 8.17 g/t Au (754,000 ounces) in the indicated mineral resource category and 10,352,000 tonnes at 7.11 g/t Au (2,366,000 ounces) in the inferred mineral resource category. For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Windfall gold project, please see the technical report entitled “Technical Report and Mineral Resource Estimate for the Windfall Lake Project, Windfall Lake and Urban-Barry Properties” and dated June 12, 2018 (effective date of May 14, 2018), which has been prepared by InnovExplo Inc. from Val-d’Or, Québec (the “Windfall Lake Technical Report”) and the press release “Osisko Releases Mineral Resource Update for Lynx” dated November 27, 2018, which has been prepared by Osisko and reviewed and approved by Micon International, Ltd. from Toronto, Ontario. The Windfall Lake Technical Report and press release are available on Osisko’s website at www.osiskomining.com and on SEDAR under Osisko’s issuer profile at www.sedar.com. The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. Mineralization occurs in four principal zones: Lynx, Zone 27, Caribou and Underdog. All zones comprise sub-vertical lenses following intrusive porphyry contacts plunging to the northeast. The deposit is well defined from surface to a depth of 900 metres and remains open along strike and at depth. Mineralization has been identified 30 metres from surface in some areas and as deep as 2,000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

OSISKO EXTENDS LYNX DEPOSIT 100 METRES DOWN PLUNGE

Posted on April 16, 2019November 8, 2023 by Yannick Fradette

New High-Grade Intercepts Including 322 g/t Au Over 4.3 Metres

Lynx Remains Open and Unexplored Below 1000 Metres Vertical Depth

(Toronto, April 16, 2019) Osisko Mining Inc. (OSK:TSX “Osisko” or the “Corporation”) is pleased to provide new results from the ongoing exploration program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

Exploration drilling has discovered a strongly mineralized extension of the Lynx deposit at approximately 1000 metres vertical depth. DDH OSK-W-19-1857 has extended Lynx 100 metres down plunge in an area outside the prior Windfall mineral resource estimate area (see Osisko news release dated November 27^th, 2018). The new exploration hole intersected a wide zone of strong silica and sericite alteration (39 metres width), containing sulfides with local gold mineralization from 1278 metres to 1317 metres downhole. The alteration zone includes three significant gold bearing intervals outlined below. The new gold intervals are between 70 metres to 270 metres distal from the previous deepest gold bearing intersects in Lynx (OSK-W-17-950, OSK-W-17-991 and OSK-W-18-1367-W2), and confirm that high grade gold mineralization remains open at depth. Further step out drilling is in progress to pursue this depth extension which has seen no previous drilling.

Osisko President and CEO John Burzynski commented: “Today’s very good results are a further confirmation that there are significant discoveries remaining to be made at Windfall. This high-grade depth extension of Lynx will be included in the mineral resource update planned for this fall. Lynx was an exciting discovery made by Osisko in early 2017, and as we have advanced work, it has increasingly become the most significant part of the Windfall deposit. We are confident that as we further explore Lynx, we will have continued discovery success.”

Sericitic alteration begins at the contact between gabbro and rhyolite units at approximately 1264 metres, increasing in intensity to a strong silica and fuchsite altered zone between 1274 metres to 1283 metres. Sericite alteration decreases at 1320 metres. Mineralization consists of disseminated pyrite, stringers, with local visible gold and native silver. Lynx is sub-vertical with a dip of 80 degrees, oriented to the NNE at 060 degrees.

Today’s results include the currently available significant analytical results from OSK-19-1857. Maps and sections showing the location of the new analytical results are available at www.osiskomining.com.

WINDFALL TRIPLE 8 DOWNHOLE IP SURVEY SUCCESSFULLY OUTLINES NEW TARGETS

Posted on March 26, 2019November 8, 2023 by Yannick Fradette

(Toronto, March 26, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to announce positive results of its hole-to-hole induced polarization (“IP”) survey conducted in the Triple 8 Zone, at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

Osisko recently used the three deep Triple 8 discovery holes (OSK-W-18-1603-W2, OSK-W-18-1616-W2 and OSK-W-18-1783) to conduct a hole-to-hole IP survey. The purpose of the survey was to attempt to outline the chargeability signature of the Triple 8 Zone; to test the lateral extension of the hole-to-hole method; and to outline new deep drill targets. The survey was successful in all aspects, and the Company intends to conduct additional hole-to-hole IP survey work to investigate the deep extensions in other areas of the Windfall deposit. The hole-to-hole IP survey and the 3D IP inversion were performed by Abitibi Geophysics Inc. from Val D’Or, Québec.

Osisko Mining President and Chief Executive Officer John Burzynski commented: “We are very excited about the off-hole targets developed using the 3D IP inversion, and the potential to use downhole geophysics to continue to outline the growing potential of the Windfall deposit at depth. We are convinced that as we advance deep exploration we will be able to grow Windfall into the same World Class category as other historic, high-grade and long-life underground mines in the Canadian Archean. Windfall has consistently shown us that the more exploration we conduct, the more new mineralization we discover – it’s the sign of a great deposit.”

Triple 8 mineralization typically consists of 10% to 30% disseminated pyrite and stringers with local visible gold in an altered andesite with local pervasive silicification and sericitization, surrounded by peripheral chlorite-biotite+/-garnet alteration. The Triple 8 Zone and the mineralized corridor responded positively to chargeability and were detected by the hole-to-hole method. Three chargeability and resistivity profiles were interpreted by pairing holes. The known mineralization was detected in the 600 metres apart pair, and subsequently validated by the two pairs approximatively 300 metres apart. The hole-to-hole method has shown to have good potential to define targets at depth and in the lateral extensions of the Windfall deposit.

Interpretation of the chargeability and resistivity profiles, and generation of a 3-dimensional data inversion highlighted two principal target areas for further exploration. The first area is located between hole OSK-W-18-1783 and OSK-W-18-1616-W2 and consists of a high chargeability centre interpreted over 300 metres wide. The second main target is approximatively 100 metres north of OSK-W-18-1603-W2.

Osisko intends to follow up the downhole IP survey with continued deep exploration drilling at Triple 8 in 2019.

About the Windfall Lake Gold Deposit

The Windfall gold deposit is located between Val-d’Or and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by Osisko, as disclosed in (i) the Windfall Lake Technical Report (as defined below), and (ii) the Lynx Resource Press Release (as defined below), comprises 2,874,000 tonnes at 8.17 g/t Au (754,000 ounces) in the indicated mineral resource category and 10,352,000 tonnes at 7.11 g/t Au (2,366,000 ounces) in the inferred mineral resource category. For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Windfall gold project, please see (i) the technical report entitled “Technical Report and Mineral Resource Estimate for the Windfall Lake Project, Windfall Lake and Urban-Barry Properties” and dated June 12, 2018 (effective date of May 14, 2018), which has been prepared by InnovExplo Inc. from Val-d’Or, Québec (the “Windfall Lake Technical Report”), and (ii) the press release of Osisko dated November 27, 2018 and entitled “Osisko Releases Mineral Resource Update for Lynx”, which has been prepared by Osisko and reviewed and approved by Micon International, Ltd. from Toronto, Ontario (the “Lynx Resource Press Release”). The Windfall Lake Technical Report and Lynx Resource Press Release are available on Osisko’s website at www.osiskomining.com and on SEDAR under Osisko’s issuer profile at www.sedar.com. The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. Mineralization occurs in four principal zones: Lynx, Zone 27, Caribou and Underdog. All zones comprise sub-vertical lenses following intrusive porphyry contacts plunging to the northeast. The deposit is well defined from surface to a depth of 900 metres and remains open along strike and at depth. Mineralization has been identified 30 metres from surface in some areas and as deep as 2,000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

Osisko Mining Inc. Announces Transaction to Spinout Non-Core Assets to Chantrell Ventures Corp.

Posted on February 20, 2019November 8, 2023 by Yannick Fradette

Not for distribution to United States newswire services or for release, publication, distribution or dissemination, directly or indirectly, in whole or in part, in or into the United States.

(Toronto, February 20, 2019) Osisko Mining Inc. (OSK:TSX, “Osisko“) and Chantrell Ventures Corp. (NEX:CV.H, “Chantrell”) are pleased to announce that they have entered into a binding letter agreement dated as of February 19, 2019 (the “Letter Agreement”) . The Letter Agreement outlines the proposed terms and conditions upon which Osisko will effect a business combination that will result in a reverse takeover of Chantrell by Osisko (the “Proposed Transaction”). Pursuant to the Proposed Transaction, Osisko will transfer certain non-core assets of Osisko with a value of approximately $99.9 million to Chantrell in exchange for shares of Chantrell. In addition the shares of Chantrell will be subject to a consolidation on a 40:1 basis, subject to adjustment.

John Burzynski, President and CEO of Osisko stated: “When we launched the new Osisko Mining in 2015 we employed the same consolidation strategy used successfully in the Malartic Camp, with the difference being we began consolidating ground in three camps. Our exceptional success at Windfall has been based on focusing all of our efforts on the Urban Barry – Quevillon district. As a result we have done only minimal work on advancing a number of our early Osisko Mining acquisitions. Drilling out the Windfall deposit and accelerating exploration on our extensive 3,500 square kilometre land package in the Urban Barry – Quevillon district will continue to be the focus of Osisko Mining. The non-core assets will now become important pieces for O3 Mining to independently continue the consolidation strategy with the objective of defining the next significant deposit in Canada’s premier mining districts.”

Terms of the Proposed Transaction

The Proposed Transaction is anticipated to be by way of plan of arrangement with approval of shareholders of Chantrell. The final structure of the Proposed Transaction will be described in an information circular of Chantrell which will be mailed to shareholders in connection with the meeting to consider the Proposed Transaction. The Osisko assets to be transferred include the Marban deposit, Garrison deposit, exploration properties and a portfolio of selected securities.

Completion of the Proposed Transaction is subject to a number of conditions, including, without limitation, negotiation and execution of definitive documentation, receipt of all necessary shareholder, third party and regulatory approvals, satisfactory completion of due diligence, conditional listing approval to list the resulting issuer (the “Resulting Issuer”) on the TSX Venture Exchange.

Chantrell intends to undertake an equity financing transaction in conjunction with the Proposed Transaction, which will consist of up to $10 million by way of a private placement of securities at a price of $3.88 per unit, each unit, consisting of one common share in the capital of the Resulting Issuer and one warrant exercisable for $4.46 to acquire a common share in the capital of the Resulting Issuer.

In connection with the Proposed Transaction, Chantrell will be required to, among other things: (i) change its name to “O3 Mining Corporation” or such other name as may be acceptable to applicable regulatory authorities; (ii) replace all directors and officers on closing of the Proposed Transaction; (iii) receive conditional listing approval for the Resulting Issuer on the TSX Venture Exchange; (iv) consolidate its common shares on a 40:1 basis, subject to adjustment; (v) cooperate in the offering of Subscription Receipts. Chantrell may, from time to time, acquire further assets in exchange for shares or cash in connection with the Proposed Transaction; and (vi) seek a waiver or exemption from the TSX Venture Exchange’s sponsorship requirements.

The Letter Agreement was negotiated at arm’s length.

Trading of Chantrell’s common shares will be halted pending further filings with the TSX Venture Exchange. Further information, including the proposed directors and officers of the Resulting Issuer will be press released by Chantrell when available.

About Osisko Mining Inc.

Completion of the Proposed Transaction is subject to a number of conditions, including but not limited to TSX Venture Exchange acceptance and if applicable pursuant to the Exchange Requirements, majority of the minority shareholder approval. Where applicable, the Proposed Transaction cannot close until the required approvals are obtained. There can be no assurance that the Definitive Agreement will be executed or that the Proposed Transaction will be completed as proposed or at all. Investors are cautioned that, except as disclosed in the disclosure document to be prepared in connection with the Proposed Transaction, any information released or received with respect to the Proposed Transaction may not be accurate or complete and should not be relied upon. Trading in the securities of Chantrell should be considered highly speculative.

John Burzynski, President and Chief Executive Officer of Osisko, commented: “We are pleased with our mineral resource estimate at Garrison and the first mineral resource estimate for the 903 Zone. Our work continues to better define the gold-bearing zones and highlight areas for future expansion and exploration. We also have numerous targets that warrant follow-up on our claim package along the significant Destor Porcupine Fault Zone.”

The mineral resource estimate has been prepared by RockRidge, from Vancouver, British Columbia, and has been reviewed and audited by Micon International Limited, Toronto, Ontario. The full technical report, which is being prepared in accordance with National Instrument 43-101 (“NI 43-101”), will be available on SEDAR (www.sedar.com) under the Corporation’s issuer profile within 45 days. The effective date of the current mineral resource estimate is February 19, 2019.

This mineral resource estimate reflects geological modeling of the Garrison deposit (Garrcon, Jonpol, and 903 zones) as lying at the confluence of the Destor Porcupine Fault and the Munro fault (a splay structure of the Destor Porcupine). Mineralization in the Garrcon Zone is in a brittle fault and fracture zone hosted within silicified metasediments. Mineralization in the Jonpol Zone is shear hosted with quartz-albite veins in sheared ultramafic volcanics within the footwall of the Munro fault. Mineralization in the 903 Zone is hosted in syenites within sheared ultramafics of the Destor Porcupine Fault.

Mineralized domain wireframes were constructed within lithological and structural boundaries modeled in Leapfrog using a 0.2 g/t Au grade shell. The estimate only considers mineralized zones potentially minable by open-pit or underground methods at lower cut-off grades of 0.4 g/t Au and 3.0 g/t Au, respectively. The cut-off calculation is based on the assumed parameters listed below:

Garrison Gold Deposit Mineral Resource Estimate Notes:

The Garrison mineral resource estimate has been prepared pursuant to CIM standards and guidelines for reporting mineral resources and reserves.
Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction.
The database comprised a total of 1,115 drill holes for 342,873.7 metres of drilling in the extent of the mineral resource, of which 197 drill holes (87,250.8 metres) were completed and assayed by Osisko as of July 31, 2018.
All NQ core assays reported by Osisko were obtained by analytical methods described below under “Quality Control and Reporting Protocols”.
Geological interpretation of the deposits was based on the Garrison deposit (Garrcon, Jonpol, and 903) as lying at the confluence of the Destor Porcupine Fault and the Munro fault (a splay structure of the Destor Porcupine) and mineralization hosted in structurally controlled domains. Interpretation was initially made from cross-sections at 25 or 50 metre intervals, and then completed in Leapfrog Software, where selections of mineralization intervals were combined to generate mineralization wireframes.
The mineralized domains used for the mineral resource estimate were constructed in Leapfrog Software using 0.2 g/t Au interpolant grade shells with 0.5 ISO values limited by hard boundaries to modeled lithological and structural zones.
Samples were composited within the mineralization domains into 2.0 metre length composites for all areas except the Garrcon Main Metasedimentary zone, where 2.5 metre composites were more appropriate.
High grade capping was done on composite data and established using a statistical analysis on a per-zone basis for gold. Capping values of between 10 g/t to 40 g/t were used depending on mineralized domain.
Density values were applied on the following lithological basis (t/m³): 2.79 for all metasedimentary units and 2.82 for all igneous units.
Ordinary Kriging (OK) based interpolation was used for the estimation of all zones of the Garrison gold deposit. Estimates are based on a block dimension of 10 metres NE, 2 metres NW and 10 metres height for all zones except the Garrcon Main Metasedimentary unit where 5 metre x 5 metre x 5 metre blocks were used. Estimation parameters were based on variography. Strong anisotropies were observed in all cases, and variograms were rotated to reflect the best major, semi-major and minor ranges. Spherical models were fitted to pairwise relative semi-variograms. Search radii reflected the orientations of the variography. Search distances were used in three passes, where the first pass equaled two thirds of the variogram range, the second pass was equal to full variogram range and the third pass was double the respective range.
The Garrison mineral resource estimate is categorized as Measured, Indicated and Inferred mineral resource as follows:
- The measured mineral resource category is generally based on a minimum number of six informing composites using a minimum of three drill holes located within the first estimation pass (two thirds variogram range)
- The indicated mineral resource category is largely based on using a minimum of four composites from two drill holes located in the second estimation pass
- The inferred mineral resource category is based on a minimum of four composites from two drill holes located in the third pass.
- After initial coding of each pass, results were further refined in Leapfrog to establish continuous volumes for each resource category.
Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
Micon International Limited is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issue not reported in the technical report, that could materially affect the mineral resource estimate.
These mineral resources are not mineral reserves as they have not demonstrated economic viability. The quantity and grade of reported Inferred resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these inferred resources as indicated or measured. It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration though not guaranteed.

About the Garrison Project
The Garrison Project area is comprised of 4 cell mineral claims and 63 patent claims encompassing approximately 770 hectares within the larger Great Bear project area which totals 517 cell mineral claims, 25 mining leases, and 87 patent claims encompassing approximately 8,000 hectares. The Garrison Project area contains the Garrcon, Jonpol, and 903 zones.

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. 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. 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%.

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. 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 Jonpol zone included the sinking of a 184 metre shaft as well as development of a ramp to the 150 metres 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.

903 Zone
This third mineralized zone present at Garrison was not included in the resource estimate reported by the previous operator in 2013. Mineralization at the 903 was discovered in 1945 by Wright-Hargreaves Mines Ltd. In 1988 Lac Minerals acquired the claims covering the current 903 Zone and completed 17 drill holes totaling 4,823 metres. The property was optioned in 1990 to Jonpol and T&H Resources and subsequently returned to Lac Minerals in 1991. The claims were acquired from a subsidiary of Barrick Gold in 2013.

OSISKO EXPANDS TRIPLE 8 DISCOVERY

Posted on January 16, 2019November 8, 2023 by Yannick Fradette

New Drilling Intersects 38.4 g/t Au Over 2.0 Metres and 16.0 g/t Au Over 2.3 Metres

Triple 8 Corridor Extends Over 750 Metres Strike Length

(Toronto, January 16, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new results from the ongoing Triple 8 deep-hole exploration program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

In May 2018 Osisko commenced deep exploration drilling to investigate the potential for depth extensions of the main mineralized zones, as well as to further test the intrusion-related geological model for the Windfall deposit. In July 2018 Osisko discovered “Triple 8”, a developing new corridor of mineralization at the Windfall deposit, at 1,425 metres vertical depth.

Today’s new drill results confirm and expand on the initial discovery (please see Osisko news releases dated July 11, 2018 and September 13, 2018). Drill hole OSK-W-18-1783 tested the continuity at the mid-point between OSK-W-18-1603 (Triple 8 discovery hole) and gold mineralization intersected in a similar setting in OSK-W-18-1616-W1 (see Osisko news release dated August 7, 2018).

OSK-W-18-1783 encountered three distinct altered intervals between 1,819 metres and 1,945 metres downhole, each averaging approximately 10 metres width. Significant results from the three gold bearing intervals include 38.4 g/t Au over 2.0 metres and 16.0 g/t Au over 2.3 metres and. Geometry is still being interpreted, however mineralization is open in all directions. Sericite and silica alteration are hosted within an andesite and gabbro package, surrounded by peripheral chlorite – biotite +/- garnet alteration (identical to that encountered in the Triple 8 discovery hole 350 metres to the north, and in hole OSK-W-1616-W1, 400 metres to the south). The mineralized intervals contain disseminated and stringer pyrite with local visible gold, and trace pyrrhotite and chalcopyrite.

Osisko President and CEO John Burzynski commented: “We have had excellent high-grade results now from the three deep holes and wedges that have intersected the Triple 8 area, including todays new results. Triple 8 is shaping up to be a significant addition to Windfall, providing good potential for the future growth of the deposit at depth. Our wide spaced exploration drilling has so far defined this new corridor over a strike length of 750 metres. We intend to conduct downhole geophysical surveys and additional drilling in the coming months, to help define the relationships between the mineralized intercepts and further define the full scale of the mineralized corridor. Overall, our large ongoing drill campaign has so far shown the Windfall mineralized system to have a strike length of 3.5 kilometres and a depth extent of 1.8 kilometres. The system remains open in all directions, and we are very confident that we can continue to grow the deposit as we advance our drilling along strike and at depth.”

Today’s results include currently available significant analytical results from OSK-18-1783, and new analytical results from OSK-W-1603-W1 and OSK-W-1616-W2. Maps showing drill hole locations and analytical results are available at www.osiskomining.com.

OSK-W-18-1783 intersected mineralization in three sericite-silica altered zones hosted within a pervasively chlorite-biotite-garnet altered andesite. The first interval (4.6 g/t Au over 3.3 metres) has moderate sericite alteration and contains up to 10% disseminated pyrite, with local pyrite clusters and stringers. The second interval (38.4 g/t Au over 2.0 metres) has strong sericite and moderate silica alteration, and is interpreted as the strike extension from the Triple 8 discovery hole. This interval contains up to 10% pyrite stringers, 5% disseminated pyrite, local visible gold and trace pyrrhotite. The third interval (16.0 g/t Au over 2.3 metres) has moderate sericite and silica alteration, and contains up to 10% pyrite stringers, 5% disseminated pyrite, local visible gold and trace pyrrhotite and chalcopyrite.

OSK-W-18-1603-W1 intersected 18.0 g/t Au over 2.4 metres within a moderate sericite and silica altered porphyritic dike intruded into the mafic volcanic sequence. Mineralization includes up to 20% pyrite stringers, 3% sphalerite and trace chalcopyrite and local visible gold. The interval is approximatively 115 metres above and to the southwest of the Triple 8 discovery in hole OSK-W-18-1603.

OSK-W-18-1616-W2 intersected 13.4 g/t Au over 2.0 metres within an approximate 35 metre pervasive chlorite and biotite altered interval within the andesite. Mineralization consists of up to 3% disseminated pyrite, local pyrite stringers and trace pyrrhotite in fracture filling or with weak silica altered bands. The interval was intersected approximatively 1,800 metres below surface and it is the deepest significant gold bearing interval in the deposit to date.
