TORONTO, June 17, 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 19 intercepts in 7 drill holes and 6 wedges from surface focused on Lynx infill drilling are presented below.  Additionally, 69 intercepts in 43 underground drill holes focused on 5 metre 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: 132 g/t Au over 5.0 metres in WST-19-0117; 51.0 g/t Au over 6.3 metres in OSK-W-19-909-W7; 56.2 g/t Au over 4.7 metres in WST-19-0106; 106 g/t Au over 2.0 metres in WST-19-0119; 82.9 g/t Au over 2.3 metres in WST-19-0113; 85.3 g/t Au over 2.0 metres in WST-19-0125; 36.0 g/t Au over 4.1 metres in OSK-W-18-1785-W1; 23.4 g/t Au over 6.3 metres in OSK-W-18-1539;  63.6 g/t Au over 2.1 metres in WST-19-0137; 59.3 g/t Au over 2.2 metres in WST-19-148;  37.0 g/t Au over 3.5 metres in WST-19-0130 and 42.1 g/t Au over 3.0 metres in WST-19-0093.

VAL-D'OR, QC, June 12, 2019  - Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR1) ("Bonterra" or the "Company") is pleased to announce drill results from the ongoing exploration campaign at its 100%-owned Gladiator, Moroy and Barry projects. The objective of the current drilling campaign is to step out from known mineralization included in the Company's recently released mineral resource estimate on the three projects.

 

Gladiator

The current drilling at Gladiator extends gold mineralization on both the Barbeau and North Zones.  Drill hole BA-19-40 intersected 101.1 g/t Au over 3.9 m on the Barbeau zone, approximately 50 m down-plunge of the known mineralization.  Drill hole BA-19-37 intersected 8.1 g/t Au over 1.8 m on the North Zone, approximately 50 m down-plunge of the known mineralization.  See section for location.

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

TORONTO, June 06, 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.
