MONTREAL, June 02, 2021 (GLOBE NEWSWIRE) -- Osisko Development Corp. (“Osisko Development” or the “Corporation”) (TSX.V-ODV) is pleased to announce drilling results from the 200,000-meter 2021 exploration and category conversion drill program campaign at its Cariboo Gold Project (“Cariboo”) in central British Columbia. A total of ten diamond drill rigs are currently at Cariboo.
Island Mountain Overview
- Mosquito Creek and Shaft Zone deposits are located on Island Mountain.
- To date in 2021, a total of 133 drill holes have been drilled on Island Mountain, designed to infill and expand known vein corridors.
- Recent results include holes IM-21-001 to IM-21-010.
- A total of 124 mineralized vein corridor solids are modelled on Island Mountain, to an average depth of 350 meters, to a maximum depth of 700 meters and remain open.
- Recent drill results show significant down dip expansion of modelled vein corridors illustrated in IM-21-009 that intersected 23.32 g/t Au over 15.0 meters.
- Detailed drilling results, a drill hole location plan map and vertical long section is presented at the end of this release.
Recent Drilling Highlights:
- 21.94 g/t Au over 2.70 meters in hole IM-21-003

- 41.30 g/t Au over 1.30 meters
- 23.32 g/t Au over 15.00 meters in hole IM-21-009 including
- 85.80 g/t Au over 1.00 meter and
- 118.50 g/t Au over 1.00 meter
- 16.83 g/t Au over 4.40 meters in hole IM-21-010 including
- 73.40 g/t Au over 0.80 meter
Chris Lodder, President of Osisko Development commented, “These first ten infill and expansion drill holes from the Mosquito Creek Deposit are showing the depth potential at Mosquito Creek and continuity between the Shaft and Mosquito deposits”.
Mineralized quartz veins on Cariboo are overall sub-vertical dip and northeast strike. Vein corridors are defined as a high-density network of mineralized quartz veins within the axis of the last folding event’s folds and hosted within a brittle meta-sandstone or calcareous meta-sandstone. Vein corridors are modelled at a minimum thickness of 2 meters and average about 4.5 meters true width. Individual mineralized veins within these corridors have widths varying from centimeters to several meters and strike lengths from a few meters to over 50 meters. These corridors have been defined from surface to a vertical depth averaging300 meters and remain open for expansion at depth and along strike. Gold grades are intimately associated with quartz vein-hosted pyrite as well as pyritic, intensely silicified wall rock haloes in close proximity to the veins.
True widths are estimated to be 60% to 75% of reported core length intervals. Intervals not recovered by drilling were assigned zero grade. Top cuts have not been applied to high grade assays. Complete assay highlights are presented in Table 1, drill hole locations are listed in Table 2.
Corporate Matters
Following the closing of the reverse takeover bid transaction by Osisko Gold Royalties Ltd (“Osisko Gold”) on November 25, 2020 which lead to the launch of the Corporation and the transfer of certain Osisko Gold employees to the Corporation on January 1st, 2021, Osisko Gold and the Corporation mutually agreed that a pro-rata portion of the outstanding long-term equity incentive compensation awarded by Osisko Gold to transferred employees in the form of restricted shares units would be borne by the Corporation.
The Boards of Directors of Osisko Gold and the Corporation, agreed that Osisko Gold would cancel a pro-rata portion of the outstanding restricted shares units awarded by Osisko Gold (“Osisko Gold RSUs”) to transferred employees and the Corporation would grant to such transferred employees restricted shares units (“Replacement RSUs”) in an equivalent value as the value of the Osisko Gold RSU cancelled by Osisko Gold; which values were determined using a 5-day volume weighted average price of the respective entity on the exchange at a pre-determined reference date.
Accordingly, the Corporation is pleased to announce that its Board of Directors has approved the grant and 404,240 Replacement RSUs were granted to officers who held Osisko Gold RSUs that were cancelled. The maturity date shall be the same as the maturity date of the corresponding Osisko Gold RSUs so cancelled.

Quality Assurance – Quality Control
Once received from the drill and processed, all drill core samples are sawn in half, labelled and bagged. The remaining drill core is subsequently stored on site at a secured facility in Wells, BC. Numbered security tags are applied to lab shipments for chain of custody requirements. Quality control (QC) samples are inserted at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QAQC program was designed and approved by Lynda Bloom, P.Geo. of Analytical Solutions Ltd.
Drill core samples are submitted to ALS Geochemistry’s analytical facility in North Vancouver, British Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is crushed, and 250 grams is pulverized. Analysis for gold is by 50g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100 ppm are re-analyzed using a 1,000g screen metallic fire assay. A selected number of samples are also analyzed using a 48 multi-elemental geochemical package by a 4-acid digestion, followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS).
