Mr. John Burzynski reports


Osisko Mining Inc. has provided new results and a geological update on the Lynx deposit from the continuing drill program at its 100-per-cent-owned Windfall Lake gold project located in the Urban township, Quebec. The current 400,000 metre drill program at Windfall combines definition drilling above the Red Dog intrusion ("Red Dog"), expansion drilling above and below Red Dog, and expansion/definition drilling in the adjacent Lynx deposit located immediately to the NE of Windfall. Maps depicting Lynx and the new drill hole locations and full analytical results are available at www.osiskomining.com.

  • Lynx deposit discovery extended by drilling to currently over 1.7 kilometres length and remains open to NE and SE
  • Recently defined "Bank Fault" interpreted as key structure associated with intrusion-related gold mineralization at Windfall and Lynx, with potential regional extent
  • 12 drills currently active on Lynx, 12 additional drills continue to define Windfall Deposit

Twenty-four drills are active on the overall Windfall Project. Twelve of those drills are currently focused on the principal Lynx deposit (Lynx HW, Lynx 1 and Lynx 2) and other subparallel Lynx zones (Lynx 3, 4, 5, and 6 and undesignated zones). Mineralization within individual zones of the Lynx deposit follow the same principal northeast oriented pathways along dike contacts as seen throughout the main Windfall deposit. One-hundred and sixty-five (165) holes have been completed in the Lynx deposit to date: complete assays have been received and released from 42 holes; partial assays have been received and released from an additional 41 holes; 82 holes are awaiting analysis.

Significant new assays from twenty-four intercepts in nineteen drill holes focused on infill and expansion drilling in the Lynx deposit are reported in the table below. Highlights from the new results include: 159 g/t Au over 2.7 metres, including 1.06 kilograms/tonne over 0.4 metres (17.0 g/t Au over 2.7 metres cut) from DDH OSK-W-17-857; 57.0 g/t Au over 2.7 (50.1 g/t Au over 2.7 metres cut) in DDH OSK-W-17-827; 57.8 g/t Au over 2.3 metres from DDH OSK-W-17-877; and 52.8 g/t Au over 2.3 metres from DDH OSK-W-17-879..

President and Chief Executive Officer John Burzynski noted: "Our exploration team has been working particularly hard over the past number of months absorbing the huge amount of new data from our large-scale drilling program, and with the new work on the Lynx discovery we are starting to see the emergence of a whole new high-grade deposit within our high-grade Windfall project. Windfall and Lynx are intrusive-related gold deposits with a proximal relationship to the Bank Fault. Although we are drilling towards a new resource estimate for Windfall by the end of this year, we believe the potential for expanding Windfall, Lynx and making new discoveries within the main deposit area is still completely wide-open."

Lynx Deposit Corridor Extended

The mineralized corridor hosting the Lynx deposit is represented by a silica-sericite alteration envelope following felsic porphyritic dikes hosted by volcanic rocks, and is further constrained between a gabbro, a brecciated felsic intrusion, and the Bank Fault which is believed to be regionally significant. The greatest abundance of visible gold observed to date in the Windfall area appears to be contained in the Lynx deposit and associated corridor. Gold mineralization follows very continuous zones of silicification that are surrounded by an outer and larger sericite envelope, accompanied by pyrite-tourmaline mineralization and hydrothermal breccias. Most drill intercepts to date range from 2 to 9 metres (core length) and reach up to 17.3 metres (core length); OSK-W-17-788, see April 5, 2017 press release).

Lynx begins near-surface, is sub-vertical, plunging 35 degrees to the northeast, and in drilling to date has been intersected 700 meters vertically below surface. The strike length of the Lynx discovery has been confirmed between sections 3050E and 4750E, extending the favourable geology 1.7 kilometers horizontally, and 1.8 kilometres in true length taking the plunge of the deposit into account. The deposit remains open to the northeast, and in potential parallel zones down-dip along the Bank Fault. Assays from holes up to section 3825E have been received and released. To date, step-out drilling has intersected geology, alteration and mineralization characteristic of the Lynx deposit to section 4750E, with 15 holes drilled between sections 3825E and 4750E, all with pending analytical results. Additional holes are planned to continue exploring the deposit which remains open in this direction.

Lynx 3, 4, 5, 6, and other new zones (undesignated at present) are subparallel mineralized zones to the main Lynx deposit (i.e. Lynx 1 + Lynx 2). Porphyritic felsic dikes hosted by volcanic rocks and associated silica-sericite alteration envelopes define these zones. Lynx 6 and other undesignated new zones are currently defined by geology, alteration and mineralization, with analytical results pending. Gold mineralization is associated with corridors of silicification with pyrite-tourmaline-sericite alteration mineralogy. Drill intercepts range from 2 to 5 meters width (core length) up to 7..7 metres width (core length). To date, Lynx 3, 4, 5, 6, and the undesignated new zones extend up to 175 metres length between sections 3350E and 3825E. The subparallel Lynx zones start within 100 metres of surface (Lynx 3) and to date have been traced to 800 metres below surface (Lynx 5). All zones remain open towards the southwest and the northeast.

A one to two metre thick corridor of quartz-carbonate crustiform veins with local visible gold is hosted within gabbro immediately below Lynx 1 / Lynx 2 and follows the same orientation. This zone has been followed up to 200 metres along strike and remains open to the NE.

The previously announced step-out hole (the "1400 metre" step-out, see February 3, 2017 press release, and subsequent "2200" metre step-out hole, which respectively correspond to deposit grid lines 4400E and 5200E) helped build the understanding of the geology the Windfall gold system. Further step-out holes along the NE corridor are planned while drilling at the Lynx deposit continues to infill the known zones and to test the continuity and extent of the Lynx deposit towards the northeast.

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 width determinations are estimated at 65 - 80% true core lengths. Assay are uncut except where indicated, and calculated intervals are reported over a minimum length of 2 metres using a lower cutoff of 3 g/t Au. All NQ core assays reported were obtained by either 1 kilogram whole rock metallic screen/fire assay or standard 50 gram fire-assaying with AA or gravimetric finish at ALS Laboratories in Val d'Or, Quebec or Sudbury, Ontario, or Bureau Veritas in Timmins, Ontario, using the same protocols. The 1 kilogram metallic 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 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 Windfall Lake Gold Deposit

The Windfall Lake gold deposit is located between Val-d'Or and Chibougamau in the Abitibi region of Quebec, 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, Quebec, 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.
