Includes 84.6 g/t Au Over 11.8 Metres, 429 g/t Au Over 2.2 Metres

(Toronto, July 8, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the ongoing definition and expansion program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. The program is currently focused 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 35 intercepts in 10 drill holes and 13 wedges from surface focused on Lynx and Main Zone infill drilling are presented below. Additionally, 34 intercepts in 20 underground drill holes focused on 5 metres infill drilling, including the pending Lynx bulk sample area, are included in a second table below.

Highlights from new infill drilling results at Lynx include: 84.6 g/t Au over 11.8 metres in OSK-W-19-909-W11; 429 g/t Au over 2.2 metres in OSK-W-19-934-W2; 149 g/t Au over 2.2 metres in WST-19-0134; 121 g/t Au over 2.3 metres in OSK-W-19-1857-W2; 119 g/t Au over 2.0 metres in WST-19-0139; 86.9 g/t Au over 2.7 metres in WST-19-0145 and 63.2 g/t Au over 2.3 metres in WST-19-0138. Maps showing hole locations and full analytical results are available at www.osiskomining.com.

Osisko President and Chief Executive Officer John Burzynski commented: “We continue to be impressed by the gold mineralization we are encountering in the infill and expansion drilling at Lynx. We are very optimistic that we will be able to add significant ounces as we progress with resource drilling and exploration of the Windfall deposit.”

Quality Control and Reporting Protocols

True width determination is estimated at 55-80% of the reported core length interval for the zone. Assays are uncut except where indicated. Intercepts occur within geological confines of major zones but have not been correlated to individual vein domains at this time. Reported intervals include minimum weighted averages of 3.0 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.

OSISKO WINDFALL ZONE 27 BULK SAMPLE RETURNS 8.53 g/t Au RECONCILED HEAD GRADE

Posted on June 11, 2019November 8, 2023 by Yannick Fradette

5,500 Tonne Sample 26% Higher Grade than Resource Model

(Toronto, June 11, 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. Results from processing 5,500 tonnes mined from Zone 27 (the “bulk sample”) have exceeded expectations, returning an average grade of 8.53 g/t Au. The bulk sample average grade is 26% higher than predicted by infill drilling on the resource block model. Mining of the bulk sample has successfully confirmed the presence of mineralization predicted in the resource model, and the analytical results have confirmed the visual mineralization encountered along the stope. Highlights and full results are presented below.

Highlights

Average grade of 8.53 g/t Au for the bulk sample 26% higher than predicted in the 12.5 metre infill drilling block model
The sample contained 1,508 ounces Au and 1,450 ounces of Ag
Average Au recovery of 93.7% achieved using contract mill
34.5% of the gold recovered in the gravity concentrate

President and Chief Executive Officer John Burzynski commented: “We are very encouraged with the better than expected results from this first bulk sample completed from the Windfall deposit. The average grade is higher than predicted by our infill drilling, and falls within our of expectations for the overall grade of the deposit. This sampling work is helping to confirm continuity, grade, recoveries and the predictability of the mineralized zones at Windfall. We are looking forward to the second bulk test in the Lynx Zone, which we expect to collect over the summer and process in October.”

Geology

The Zone 27 bulk sample is characterized by a sub-vertical zone of sulphides in a strong silica alteration envelope averaging 1.5 metres thick, hosted in a strong sericite altered porphyritic dike containing disseminated pyrite. Mineralization consists of up to 30% pyrite stringers, up to 20% disseminated pyrite, with trace chalcopyrite and sphalerite. Visible gold was observed locally, predominantly in silica fracture filling. Geological mapping during the bulk sample has shown that the mineralized zone is very distinctive and identifiable on the mining face.

Processing

A total of 2,080 tonnes (mined in October – November 2018) were processed in December 2018 (see Osisko news release dated December 18, 2018). Subsequently, 3,420 tonnes (mined in January 2019) were processed in May 2019.

The bulk sample test was performed at the Northern Sun Redstone concentrator at an average throughput of 30 tonnes per hour. Processing produced gravity and flotation concentrates. Ore transportation trucks were sampled for moisture and weighed on a calibrated weight scale. The sample material was crushed and milled to a particle size favorable to the flotation recovery process. Gravity and flotation concentrates produced were weighed and sent to a local smelter for sale. Daily composite samples of streams for the reconciliation process were prepared and analyzed by an external independent lab. Concentrate production tonnage and assays were used to reconcile the bulk sample mass balance process in the concentrator. The reconciliation was performed by an external independent consultant using Bilmat (a reconciliation software) on a dry tonnes basis.

The reconciled head grade is 8.53 g/t Au and 8.20 g/t Ag. The sample contained 1,508 oz Au and 1,450 oz Ag, and a total of 1,413 oz Au and 1,355 oz Ag were recovered. Reconciled recoveries are 93.7% for gold and 93.4% for silver. The Preliminary Economic Assessment (or “PEA”, see Osisko news release dated July 17^th, 2018) metallurgical test work considered a communition, gravity and carbon in leach process flowsheet, giving an average recovery of 92.5% for Zone 27. Test mill availability dictated the use of a mill with a comminution, gravity and flotation flowsheet. The reconciled results from the processing of the bulk sample material are presented in Table 1 below:

The area mined was located in mineralization wireframe 115 from the Windfall resource block model. The area was prepared for mining with infill drilling at 12.5 metre spacing. The same parameters used in the May 2018 Mineral Resource Estimation (see Osisko news release dated May 14, 2018) were used for an internal update of the resource block model in the bulk sample area. The infill drilling block model predicted 5,512 tonnes at 6.76 g/t Au containing 1,198 ounces of gold inside the excavated area (see Table 2 below).

Concentrates

Both the gravity concentrate and flotation concentrate produced from the sample are considered high-grade. The gravity concentrate averaged 1,389 g/t Au (44.7 oz/T Au), while the flotation concentrate averaged 69.8 g/t Au (2.2 oz/T Au), or respectively CDN$75,479/t and CDN$3,790/t (using US$1300/oz and 1.3 US/CDN exchange rate). Further work will be conducted on the process flowsheet prior to feasibility in light of these high-value numbers.

Mining and Grade Control

The bulk sample area displayed excellent ground conditions. The sample was mined through conventional development methods following the orebody in an ENE-WSW direction over approximatively 56 metres. Rounds were 5.5 metres high, between 2.4 – 3.0 metres deep with an average width of 4 metres. Selective blasting was performed (with an ore blast and a marginal blast) depending on ore thickness and the presence of the Red Dog dike. Benches were performed on the floor over 20 metres and in the access level in order to capture ore along the plunge of the mineralized zone. Channel sampling in the drift face and muck sampling was conducted after each round. Channel and muck assays dictated what material was shipped to the mill for processing.

Technical Info, Quality Control and Reporting Protocols

Process reconciliation was performed using Bilmat software and validated by an external consultant. Daily and global reconciliations were performed. Daily Mill throughput was estimated using the load cell on the Redstone primary ball mill feed conveyor. Daily composite samples were taken on streams required for reconciliation. Global Mill throughput was estimated based on the Redstone Mill truck scale which is calibrated once per year. Global flotation concentrate was weighed on the same truck scale and samples were taken from each bucket used to load the concentrate trucks. Global gravity concentrate was weighed on a scale and each bag was drill sampled. All samples were sent out to an external independant lab for preparation and assaying. They were all assayed for gold, silver, iron, sulfur and moisture. Gold assay from gravity concentrate was obtained by screened metallics fire assay. For all the other samples, gold assay was obtained by fire assay AA finish or gravimetric finish.

OSISKO DISCOVERS NEW GOLD ZONE AT FOX

Posted on June 6, 2019November 8, 2023 by Yannick Fradette

16.7 g/t Au over 2.8 Metres

(Toronto, June 6, 2019) Osisko Mining Inc. (OSK: TSX. “Osisko” or the “Corporation”) is pleased to announce the discovery of a new gold bearing zone at its 100% owned Urban Barry gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

The new gold zone (“Fox West”) is located two kilometres south-west of the Fox discovery (see Osisko news releases August 29, 2016 and November 23, 2016) and consists of pyrite stringers hosted in a sericite altered dacite/ felsic intrusion.

Fox West is located in a six kilometre east-north-east corridor of altered porphyry dykes hosted in mafic volcanics containing a number of historic and recent gold occurrences. The Fox corridor is located approximately five kilometres northwest of the Windfall deposit. Gold mineralization in Fox West is associated with hematite altered felsic intrusions and occurs in both the hanging wall and footwall of the units. Mineralization in this new zone is similar to Windfall and the initial 2016 Fox discovery, occurring along intrusive porphyry contacts.

Osisko President and Chief Executive Officer John Burzynski commented: “Renewed shallow exploration drilling at Fox has turned up significant new results two kilometres to the west of the initial Fox discovery holes. The similarities between the mineralization style at Fox and Windfall make for the exciting possibility of developing another deposit in parallel with our ongoing program at Windfall. Additional exploration holes between the initial discovery area and Fox West are planned.”

Maps showing drill hole locations and full analytical results are available at www.osiskomining.com.

OSISKO 400 METRE HIGH-GRADE EXTENSION AT LYNX

Posted on June 3, 2019November 8, 2023 by Yannick Fradette

33.4 g/t Au Over 3.7 Metres

(Toronto, June 3, 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 on the Lynx deposit has intercepted a high-grade mineralized extension 400 metres down-plunge from the nearest resource wireframe (see Osisko news release dated November 27^th, 2018), and 300 metres down plunge from recent high-grade intercepts including 322 g/t Au over 4.3 metres in OSK-W-19-1857 (see Osisko news release dated April 16, 2019). Drill hole OSK-W-19-991-W2 intersected 33.4 g/t Au over 3.7 metres at approximately 1200 metres vertical depth within a strong silica and sericite alteration zone containing sulfides with local visible gold.

Osisko President and Chief Executive Officer John Burzynski commented: “Deeper drilling at Windfall continues to pay off. The new extension of Lynx brings great potential for adding significant new high-grade ounces to the deposit. This step-out clearly demonstrates that strong mineralization continues at depth. Infill drilling up-plunge and further step-out drilling down-plunge is in progress.”

Mineralization in hole OSK-W-19-991-W2 is hosted in a strongly silicified and brecciated felsic dike at the contact with an andesitic unit. The mineralized interval contains up to 25% fine-grained pyrite-tourmaline, trace chalcopyrite, local visible gold as stringers and fracture filing within quartz-carbonate veins, quartz-tourmaline veinlets with local visible gold, and 5% stringer or stockwork pyrite.

Maps and sections showing the location of the new analytical results are available at www.osiskomining.com.

OSISKO INFILLS NEW HIGH GRADE AT LYNX

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

New Intersections Include 96.7 g/t Au Over 4.8 Metres, 37.6 g/t Au Over 7.8 Metres

(Toronto, May 30, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the ongoing definition and expansion program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

The program includes 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 52 intercepts in 15 drill holes and 9 wedges focused on infill drilling from surface and underground are presented below.

Osisko President and Chief Executive Officer John Burzynski commented: “Our infill drill program at Windfall continues to give us confidence that we will see strong results when we table our next resource estimate later this year. We are having great success at the drill bit, particularly from the Lynx Zone which remains open to depth with excellent grades. Day-by-day our exploration team is growing the Windfall deposit, confirming our belief that we are onto a world-class high-grade system.”

Highlights from new infill drilling results include: 96.7 g/t Au over 4.8 metres in OSK-W-19-1891; 189 g/t Au over 2.4 metres in OSK-W-19-1831; 86.9 g/t Au over 3.7 metres in OSK-W-18-1477; 75.8 g/t Au over 4.0 metres in OSK-W-19-1181-W7; 37.6 g/t Au over 7.8 metres in OSK-W-17-934-W4; 105 g/t Au over 2.2 metres in OSK-W-18-1477 and 26.0 g/t Au over 7.9 metres in OSK-W-19-1414-W8.

OSISKO DISCOVERS NEW NEAR SURFACE HIGH-GRADE GOLD ZONE AT WINDFALL

Posted on May 28, 2019November 8, 2023 by Yannick Fradette

Intercepts Include 393 g/t Au over 2.2 Metres and 31.0 g/t Au over 6.1 Metres

(Toronto, May 28, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to announce the discovery of a new shallow gold bearing zone at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

The new zone (“Windfall North”) was discovered in a previously unexplored area 350 metres north of the main deposit, and consists of gold-bearing quartz veins hosted in a silica-carbonate-sericite alteration envelope locally up to six metres wide. Mineralization occurs between 50 metres – 275 metres vertical depth from surface and remains open at depth and along strike, as two sub-parallel zones following the same general trend of the main deposit (zones plunging at 45 degrees NE).

Osisko President and Chief Executive Officer John Burzynski commented: “Our extensive drill program at Windfall is continuing to deliver positive results on infill, expansion and exploration near the main deposit. This new shallow high-grade discovery is a very positive sign that there is good potential to add new ounces near surface. We expect to continue to grow the size of our deposit as we advance our work at Windfall, both near surface and with our deep drilling program.”

Highlights from the discovery include: 393 g/t Au over 2.2 metres in OSK-W-19-1883; 31.0 g/t Au over 6.1 metres in OSK-W-19-1911; and 82.9 g/t Au over 2.3 metres in OSK-W-19-1835. Maps showing drill hole locations and full analytical results are available at www.osiskomining.com.

Quality Control and Reporting Protocols

True width determination 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.

Chantrell Enters Into Definitive Arrangement Agreements With (i) Osisko Mining For Previously-Announced Spin-Out Transaction, And (ii) Alexandria Minerals For Business Combination With The Resulting Issuer – “O3 Mining Inc.”.

“O3 Mining Inc.” Will Be Well-Capitalized And, With The Support of Management of Osisko Mining, Its Mission Will Be To Acquire and Develop Mining Properties, With A Bias Towards Gold Properties Located In Ontario and Québec.

O3 Mining Inc. will:

be well-capitalized with approximately CDN $28-30 million in cash and marketable securities;
be supported by the proven board and management team of Osisko Mining; and
have a mandate to acquire and develop prospective gold properties and advanced staged gold assets in Ontario and Québec.

Toronto, Ontario (May 14, 2019) – Chantrell Ventures Corp. (NEX:CV.H) (“Chantrell“) is pleased to announce that it has entered into a definitive arrangement agreement with Alexandria Minerals Corporation (TSX-V:AZX; OTCQB:ALXDF; Frankfurt:A9D) (“Alexandria“) dated May 14, 2019 (the “Alexandria Arrangement Agreement“), pursuant to which, among other things, following the acquisition of certain non-core assets of Osisko Mining Inc. (OSK:TSX) (“Osisko Mining“) by Chantrell, which will result in the reverse-take over (the “Reverse Take-Over“) of Chantrell by Osisko Mining, the resulting issuer, which will be renamed “O3 Mining Inc.” (“O3 Mining” or the “Resulting Issuer“), will acquire all of the issued and outstanding common shares of Alexandria pursuant to a statutory plan of arrangement under Section 192 of the Canada Business Corporations Act(the “Alexandria Arrangement“).

Under the Alexandria Arrangement, shareholders of Alexandria (“Alexandria Shareholders“) (other than Alexandria Shareholders validly exercising their dissent rights, if any) will be entitled to receive 0.010309 common shares of O3 Mining (on a post-Consolidation (as defined below) basis) in exchange for each Alexandria share held immediately prior to the effective time of the Alexandria Arrangement.

The Alexandria Arrangement has been priced based on deemed value of CDN $3.88 per common share of O3 Mining (on a post-Consolidation (as defined below) basis), being the purchase price of subscription receipts issued under Chantrell’s CDN $18.2 million financing, and values the common shares of Alexandria at CDN $0.04 per share. The deemed purchase price of CDN $0.04 per common share of Alexandria represents a premium of approximately 18{4a519b2e1b7ee41c07b52bf609655ec62dee46aaa3d3e6dbc7220444390e11ca} over the five-day volume weighted average price (“VWAP“) and approximately 23{4a519b2e1b7ee41c07b52bf609655ec62dee46aaa3d3e6dbc7220444390e11ca} over the 20-day VWAP of common shares of Alexandria on the TSX Venture Exchange as of the close of trading on May 13, 2019.

Walter Henry, the Interim President and Chief Executive Officer of Alexandria commented: “This transaction will fold Alexandria’s key Val d’Or land package into O3 Mining’s exploration properties at an early stage of O3 Mining’s history. With its proven team of Québec explorers, strong balance sheet and available sources of funding, we believe that the O3 team will be able to apply their technical expertise to properly explore the Alexandria properties and maximize their long-term potential for all of O3 Mining’s stakeholders, including Alexandria’s current shareholders.”

Chantrell is also pleased to announce, further to its announcements dated February 20, 2019 and March 27, 2019, that it has entered into a definitive arrangement agreement with Osisko Mining dated May 14, 2019 (the “Osisko Arrangement Agreement“), pursuant to which, among other things, certain non-core assets of Osisko Mining will be transferred to Chantrell, resulting in the Reverse Take-Over of Chantrell by Osisko Mining, by way of a statutory plan of arrangement under Section 182 of the Business Corporations Act(Ontario).

See press releases of Chantrell dated February 20, 2019 entitled “Osisko Mining Inc. Announces Transaction to Spinout Non-Core Assets to Chantrell Ventures Corp.”and dated March 27, 2019 entitled “Osisko Mining Inc. – Chantrell Ventures Corp. Transaction Update”.
