OSISKO ANNOUNCES RENEWAL OF NORMAL COURSE ISSUER BID
(Toronto, December 28, 2018) Osisko Mining Inc. (TSX:OSK) (the “Corporation” or “Osisko“) today announces renewal of the normal course issuer bid program of the Corporation to purchase for cancellation, from time to time over a 12-month period, common shares of the Corporation (“Common Shares“) listed on the Toronto Stock Exchange (“TSX“) in an aggregate amount of up to 10% of the “public float” of the Corporation (the “NCIB Program“), being 14,251,609 Common Shares.
Repurchases under the NCIB Program may commence on January 2, 2019 and will terminate on January 1, 2020 or on such earlier date as the NCIB Program is complete. Purchases of Common Shares under the NCIB Program will be made in Canada through the facilities of the TSX in accordance with its rules. Daily purchases will be limited to 208,038 Common Shares, other than block purchase exemptions, representing 25% of the average daily trading volume of the Common Shares on the TSX for the six month period ending November 30, 2018, being 832,152 Common Shares.
The price that the Corporation may pay for any Common Shares purchased under the NCIB Program will be the prevailing market price at the time of purchase and any Common Shares purchased by the Corporation will be cancelled. The actual number of Common Shares repurchased under the NCIB Program and the timing of such repurchases will be at Osisko’s discretion and shall be subject to the limitations set out in the TSX Company Manual.
The board of directors of Osisko believes that the underlying value of the Corporation may not be reflected in the market price of the Common Shares from time to time and that, accordingly, the purchase of Common Shares will increase the proportionate interest in the Corporation of, and be advantageous to, all remaining shareholders of the Corporation
As of December 27, 2018, there were 257,189,331 Common Shares issued and outstanding, and the Corporation had a public float of 142,516,096 Common Shares.
Osisko has appointed BMO Nesbitt Burns Inc. to make any purchases under the NCIB Program on its behalf. The commencement of the NCIB Program is subject to TSX approval.
During the prior NCIB Program of the Corporation, which commenced on December 29, 2017 and will terminate on December 28, 2018, Osisko had approval to acquire up to 15,204,587 Common Shares, but nil Common Shares were acquired.

OSISKO WINDFALL INITIAL BULK SAMPLE RETURNS 9.7 g/t Au HEAD GRADE
39% Higher Grade than Resource Model
(Toronto, December 18, 2018) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide preliminary results from Zone 27 bulk sampling. The Zone 27 bulk sample is the first of three planned 5,000 tonne samples in the ongoing evaluation work at the Windfall project.
Results below represent 2,078 tonnes mined from Zone 27 wireframe 115. The balance of 2,922 tonnes will be processed in the new year, with reconciled results from the full 5,000 tonne sample expected to be available by March 2019.
The average head grade obtained from the 2,082 tonnes is 9.7 g/t Au and 5.5 g/t Ag. These initial results successfully confirm prior drill hole information and the visible mineralization along the mined portion of Zone 27. The average head grade from the sample is 39% higher than indicated in the resource block model for this area of Zone 27 (7.0 g/t Au). Results are presented in the table below:

Osisko President and CEO John Burzynski commented: “We are very pleased to deliver an early Christmas gift to our shareholders with these great preliminary results from the Zone 27 bulk sample. Having the grade come in 39% higher than anticipated is a strong result, and it is particularly encouraging given the recent increase in grades shown in the Lynx Zone resource update (see Osisko news release dated November 27, 2018). The infill drilling program, recent resource update and now the initial bulk sampling results have all been demonstrating that the more detailed work we do at Windfall, the better it gets.”
Mill feed tonnages were provided by the custom mill used in the sample processing (Northern Sun Mining, operator of the Redstone mill in Timmins region, Ontario). Daily composite samples collected during the processing of the bulk sample were assayed by ALS Laboratories in Val d’Or.
Processing and Resource Block Model Reconciliation
Processing of the bulk sample produced gold/silver gravity and flotation concentrates. The first 2,078 tonnes has been processed at an average throughput of approximately 350 dry tonnes per day. The total amount of gold and silver contained and produced from the full 5,000-tonne bulk sample, incorporating all underground data, will be used to reconcile the representative area in the Zone 27 resource block model once the full sample has been processed.
The resource block model was upgraded in this part of the deposit using recent 12.5 metre infill drilling and PEA block modelling parameters, and an average of grade of 7.0 g/t Au was estimated in the area mined. The preliminary results returned 9.7 g/t Au head grade from the first 2,078 tonnes test milled. PEA metallurgical testwork indicated recovery of 92.5% for Zone 27 (communition, gravity and whole ore leach) which is most appropriate given the nature of ore. Test mill availability dictated using a mill with a different process flowsheet consisting of comminution, gravity and flotation. Final recoveries will be determined in the new year based on the concentrate volumes and reconciliation upon the completion of processing of the full 5,000 tonne sample. Osisko’s current mill design work anticipates using communition, gravity and whole ore leach as noted in the PEA and the Corporation anticipates ultimate recoveries to be within the parameters outlined (92.5%) from the metallurgically simple ore at Windfall.

About the Windfall Lake Gold Deposit
The Windfall Lake 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 Lake 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 news 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 news 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 RELEASES MINERAL RESOURCE UPDATE FOR LYNX
Grade and Ounces Increase with Infill Drilling
(Toronto, November 27, 2018) Osisko Mining Inc. (OSK:TSX, “Osisko” or the “Corporation”) is pleased to provide an update on the Lynx zone mineral resource estimate at its 100% owned Windfall Project, located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.
Highlights include:
- Grade increase in Lynx indicated resource to 8.13 g/t Au
- Grade increase in Lynx inferred resource to 9.70 g/t Au
- Addition of 153,000 ounces to Lynx indicated resource
- Addition of 82,000 ounces to Lynx inferred resource
- Global Windfall indicated resource increases to 754,000 oz Au averaging 8.17 g/t Au
- Global Windfall inferred resource increases to 2,366,000 oz Au averaging 7.11 g/t Au

Note: (1) Values are rounded to nearest thousand which may cause apparent discrepancies.
The updated mineral resource estimate includes 138 infill drill holes (107,366 metres) completed in the Lynx resource area by Osisko between March 6, 2018 and October 27, 2018. In total, the updated mineral resource estimate includes 613 holes (370,714 metres) drilled in the Lynx zone by Osisko since 2017. Conversion drilling (from inferred category to indicated category) continues at the Windfall deposit on all zones (Zone 27, Caribou, Underdog, and Lynx). The complete Windfall mineral resource estimate update is scheduled for release in 2019 upon the completion of the ongoing infill drilling program.
John Burzynski, President and Chief Executive Officer commented: “We are very pleased with the updated mineral resource estimate on Lynx. Our work has positively demonstrated that conversion of inferred resources to indicated resources, and infilling in general, is resulting in higher average grades and is adding ounces. Osisko’s Lynx discovery now represents over one million ounces of the global resource, and we are confident that as we complete the infill drilling we will continue to see the average indicated grade move up. The higher grades and additional ounces shown in today’s updated resource will also have a strong positive effect on the robust Windfall PEA released in July 2018.”
Additionally he noted: “We now have a very significant global resource between Windfall (2,874,000 tonnes averaging 8.17 g/t Au for 754,000 indicated ounces gold, and 10,352,000 tonnes averaging 7.11 g/t Au for 2,366,000 inferred ounces gold) and Osborne Bell (2,587,000 tonnes averaging 6.13 g/t Au for 510,000 ounces gold inferred). The Windfall intrusive-related gold system remains open along strike and at depth. Lynx and several of the other known zones have excellent down plunge potential to add mineral resources, and as we progress with our 800,000 metre drill program we expect to continue expanding Windfall. Today’s positive results will be followed up by further grade confirmation work, including the initial results from our bulk sampling of Zone 27, which is on schedule to be released before the end of December 2018. We are also continuing with deep drilling on our Triple 8 discovery, and anticipate news from the current hole in progress by the end of January 2019. Osisko remains well financed as one of the most aggressive gold explorers in the business.”
The updated mineral resource estimate for Lynx was prepared by Osisko and reviewed and audited by Micon International Limited, Toronto, Ontario. The interim update used the same methodology (key assumptions, parameters and methods) as the Windfall Lake Technical Report (as defined below), which is available on SEDAR (www.sedar.com) under Osisko’s issuer profile. Infill drilling focused primarily on zones above 500 metres. Additional but limited infill drilling was also completed on zones below 500 metres. A total of 37 wireframes were updated and two new wireframes created for the interim estimate with a minimum true thickness of 2.0 metres. Wireframes in Lynx were updated and created using the same geological model of intrusive-related systems where mineralized zones are closely associated with sub-volcanic quartz-feldspar porphyries as previously used.
Average grades for indicated and inferred resources are weighted averages of indicated and inferred classified blocks from all 39 different sized wireframes. The increase in indicated resources was expected as infill holes continue to intersect high grade zones and improve continuity. The grade increase in inferred is due to the overall grade increase from additional holes in five wireframes representing approximately 75% of the inferred ounces. The estimate only considers mineralized zones potentially minable by underground methods at a lower cut-off grade of 3.0 g/t Au. The cut-off calculation is based on the assumed parameters listed below:

Windfall Gold Deposit Mineral Resource Estimate Notes
- The Windfall mineral resource estimate has been prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum’s standards and guidelines for reporting mineral resources and mineral reserves.
- Resources are presented undiluted and in situ and are considered to have reasonable prospects for economic extraction.
- The database comprised a total of 1,591 drill holes for 704,099 metres of drilling in the extent of the mineral resource, of which 950 drill holes (521,058 metres) were completed and assayed by Osisko as of October 27, 2018, on approximate grid of 25 metre x 25 metre (infill drilling) and larger grid for extension drilling.
- 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 lithologies, mineralized shears and the observation that most mineralized domains occur at the contact of porphyry dykes and volcanic host rocks. Interpretation was initially made from cross-sections at 50 metre intervals, and then completed in Leapfrog, a modelling software, where selections of mineralization intervals were combined to generate mineralization wireframes. Domains are subvertical, strike NE-SW and plunge approximately 30 degrees towards the North-East.
- The mineral resource estimate encompasses a total of 126 tabular, sub-vertical gold-bearing domains each defined by individual wireframes with a minimum true thickness of 2.0 metres.
- Samples were composited within the mineralization domains into 2.0 metre length composites. A value of zero grade was applied in cases of core not assayed.
- High grade capping was done on composite data, and established using a statistical analysis on a per-zone basis for gold. Capping varied from 15 g/t Au to 75 g/t Au and was applied using a four-step capping strategy where capping values decreased as interpolation distances increased.
- Density values were applied on the following lithological basis (t/m3): mafic volcanic host rocks varied from 2.78 to 2.86; felsic volcanic host rocks varied from 2.76 to 2.77; porphyries varied from 2.70 to 2.83.
- Ordinary Kriging (OK) based interpolation was used for the estimation of all zones of the Windfall gold deposit except for the Underdog zone where an Inverse Distance Squared (ID2) interpolation was preferred due to the larger drill spacing and smaller density of drill holes informing the mineralization wireframes. All estimates are based on a block dimension of 5 metres NE, 2 metres NW and 5 metres height and estimation parameters determined by variography.
- The Windfall mineral resource estimate is categorized as indicated mineral resource and inferred mineral resource as follows:
- The Indicated mineral resource category is manually defined and encloses areas where drill spacing is generally less than 25 metres, blocks are informed by a minimum of three drill holes, and reasonable geological and grade continuity is shown.
- The Inferred mineral resource category is manually defined and encloses areas where drill spacing is less than 100 metres, blocks are informed by a minimum of two drill holes, and reasonable, but not verified, geological and grade continuity is observed.
- 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 do not have 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.

The scientific and technical content in this press release has been reviewed and approved by Mr. Mathieu Savard, P.Geo (OGQ #510), Vice President Exploration (Québec) of Osisko, who is a “qualified person” within the meaning of 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 (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 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.
Cautionary Statements Regarding Estimates of Mineral Resources
This press release uses the terms measured mineral resource, indicated mineral resource and inferred mineral resource as a relative measure of the level of confidence in the mineral resource estimate. Readers are cautioned that mineral resources are not mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. The estimate of mineral resources may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s “CIM Definition Standards on Mineral Resources and Mineral Reserves” incorporated by reference into NI 43-101. Under NI 43-101, estimates of inferred mineral resources may not form the basis of a feasibility or pre-feasibility study or economic analysis of mineral resources, except for a “preliminary economic assessment” as defined under NI 43-101. Readers are cautioned not to assume that further work on the stated mineral resources will lead to mineral reserves that can be mined economically.

About the Windfall Lake Gold Deposit
The Windfall Lake 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), comprises 2,382,000 tonnes at 7.85 g/t Au (601,000 ounces) in the indicated mineral resource category and 10,605,000 tonnes at 6.70 g/t Au (2,284,000 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 Lake 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”). The Windfall Lake Technical Report is 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 2000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

OSISKO INTERSECTS 83.9 g/t Au OVER 5.3 METRES AT LYNX
Resource Update on Schedule
(Toronto, November 21, 2018) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the ongoing drill definition and expansion 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 commenced in late 2015. The program is currently focussed on infill drilling within the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall), exploration and expansion drilling on the main mineralized zones, and deep exploration in the central areas of the intrusive system. Significant new analytical results from 53 intercepts in 23 drill holes and 6 wedges focused on infill drilling are presented below.
The database for the Lynx interim resource update was closed on October 27th, 2018. Results are on schedule to be released prior to the end of the month. This interim resource update is focused on the Lynx zones above 500 metres, and was planned in May 2018 as a follow-up to demonstrate the results of infill drilling on the May 2018 preliminary resource estimate (see Osisko press release dated May 14, 2018). The complete Windfall resource is scheduled for release in 2019 upon the completion of the ongoing infill drilling program.
Bulk sampling in Zone 27 is also progressing, with over 1,000 tonnes of sample material already shipped to the custom processing facility in Ontario. Preliminary results from Zone 27 bulk sampling are also on schedule to be available before the end of December.
Highlights from today’s new infill drilling results include: 83.9 g/t Au over 5.3 metres and 89.3 g/t Au over 2.4 metres in OSK-W-18-1731; 56.3 g/t Au over 3.3 metres in OSK-W-18-1728-W1; 29.3 g/t Au over 2.9 metres in OSK-W-18-1738; 27.2 g/t Au over 2.6 metres in OSK-W-18-1508; 23.7 g/t Au over 2.9 metres in OSK-W-18-1754 and 13.5 g/t Au over 4.7 metres in OSK-W-18-1762.

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 Osisko’s 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 width determination is currently unknown but is estimated at 65-80% 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 3.0 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 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-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), comprises 2,382,000 tonnes at 7.85 g/t Au (601,000 ounces) in the indicated mineral resource category and 10,605,000 tonnes at 6.70 g/t Au (2,284,000 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 Lake 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”). The Windfall Lake Technical Report is 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 2000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

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 Osisko’s 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 width determination is currently unknown but is estimated at 65-80% 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 3.0 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 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-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), comprises 2,382,000 tonnes at 7.85 g/t Au (601,000 ounces) in the indicated mineral resource category and 10,605,000 tonnes at 6.70 g/t Au (2,284,000 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 Lake 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”). The Windfall Lake Technical Report is 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 2000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

OSISKO WINDFALL EXPLORATION RAMP ACHIEVES UNDERGROUND ACCESS TO ZONE 27
(Toronto – October 11, 2018) Osisko Mining Inc. (the “Company” or “Osisko”) (TSX:OSK) is pleased to announce that last night the Windfall exploration ramp achieved access to Zone 27, wireframe 115, selected for the initial 5,000 tonne bulk sample (see photo 1 below). The mineralized zone is strongly silicified with sulfides and contains local visible gold (see photo 2 below). The geology observed compares very well with the anticipated zone predicted by drilling and the geological model. The exploration ramp also encountered a mineralized section containing local visible gold in wireframe 101 immediately prior to achieving the targeted 115 wireframe bulk sample area (see photo 3 below). Work in the exploration ramp over the coming weeks will now be focused on collecting the bulk sample which will be transported to a custom milling facility in Ontario for processing in November.

Mineralization has been identified 30 metres from surface in some areas and as deep as 2000 metres in others, with significant potential to extend mineralization down-plunge and at depth.
