"Osisko Development Announces Initial Mineral Resource Estimate for Trixie, Tintic Project



213 koz of Gold grading 28.1 g/t and 385 koz of Silver grading 50.8 g/t in Measured and Indicated Resources1
243 koz of Gold grading 19.6 g/t and 530 koz of Silver grading 42.8 g/t in Inferred Resources1

MONTREAL, Jan. 17, 2023 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce an initial mineral resource estimate ("MRE") for its 100%-owned underground Trixie deposit ("Trixie") (the "Trixie MRE"), within the Company's wider Tintic Project ("Tintic" or the "Tintic Project"), located in the historic East Tintic Mining District in central Utah, U.S.A.

Chris Lodder, President of Osisko Development commented, "The initial Trixie MRE reflects a very limited footprint of the historically defined mineralized zones at Trixie and was delineated within only six months of the acquisition of the project. It exhibits outstanding precious metal grade potential within the structural corridors of the host quartzite and based on all data received and compiled to date we see potential to continue to extend mineralization at depth and on strike throughout and parallel to the historic mine footprint as well as repeats at several other prospects and past producers in the East Tintic District. This resource will assist the Company with its near-term exploration and operational planning."

TRIXIE MINERAL RESOURCE ESTIMATE

The Trixie MRE comprises five mineralized zones within the greater Trixie deposit, including T1, T2, T3, T4 and 75-85 zones over a strike length of 610 meters ("m"), a maximum width of 105 m and to a maximum depth of 295 m.
The Trixie MRE is based on 4,467 underground chip samples, 4,780.1 m of current and verified historic drilling in 50 holes, of which 3,228.9 m of drilling in 23 holes were drilled by the Company in 2022.
Gold mineralization is associated with high sulphidation epithermal mineralization, structurally controlled, and hosted within the quartzites. Mineralization consists of native Au, and rare Au-Ag rich telluride minerals with quartz and quartz-barite-sulphosalt stockwork veining."

"MONTREAL, Aug. 08, 2023 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to report its financial and operating results for the three months ended June 30, 2023 ("Q2 2023").

Q2 2023 HIGHLIGHTS

Operating, Financial and Corporate Updates:

3,830 ounces of gold sold by the Company from operating activities, comprising of:
1,576 ounces of gold sold from the Trixie test mine ("Trixie") located within the Company's wider Tintic Project;
1,244 ounces of gold sold from the San Antonio Gold Project ("San Antonio") by processing stockpiles via heap leaching; and
1,010 ounces of gold sold from the Cariboo Gold Project ("Cariboo") by processing stockpiles at a third-party processing facility.

$10.8 million in revenues and $11.4 million in cost of sales generated from operating activities.
On May 5, 2023, the Company announced the supplemental listing of certain previously-issued common share purchase warrants of the Company ("Warrants") on the TSX Venture Exchange (the "Exchange") effective as of the opening of markets on May 8, 2023. These Warrants include: (i) an aggregate 7,752,916 Warrants expiring on March 2, 2027, and (ii) an aggregate 11,363,933 Warrants expiring on May 27, 2027 (see news release dated May 5, 2023). These Warrants have been subsequently listed for trading on the Exchange under the symbols "ODV.WT.A" and "ODV.WT.U", respectively.
The Company announced the results of its annual meeting of shareholders held on May 11, 2023, and on June 30, 2023, granted deferred share units of the Company ("DSUs") to its independent directors as part of its regular annual remuneration program, in accordance with the DSU Plan of the Company.
As at June 30, 2023, the Company had approximately $86.9 million in cash.
Based on current projections, the Company believes that the capital resources available to Osisko Development as at June 30, 2023 are insufficient to fund its planned development, exploration and corporate activities for the next 12 months. To execute on its planned activities, the Company will need to seek additional funding and/or make adjustments to the timing thereof or reduce planned expenditures. The Company is exploring options to secure additional financing; however, there is no assurance that future financing(s) will be available or be available on favorable terms (refer to Note 1 in the financial statements relating to going concern).

Tintic Project – Utah, U.S.A. (100%-owned)

Approximately 85% of the 1,390 meter ("m") (or 4,550 feet ("ft.")) of the Trixie portal and underground decline ramp has been completed as at June 30, 2023. The Company anticipates completion of the decline ramp to the main 625 feet underground level by Q3 2023.
Target to ramp up processing capacity to 500 short tons per day is subject to completion of required mine and mill infrastructure upgrades, updated mineral resources estimate ("MRE") and ongoing technical work. Small-batch VAT leaching recommenced during the quarter as the Company advanced ongoing technical work in connection with the required mine and mill infrastructure upgrades.
During the quarter, the Company continued underground exploration and delineation activities on the existing Trixie deposit with two diamond drill rigs operating as part of its 2023 underground infill and exploration program targeting a total of 5,000 m (16,404 ft.).
As of June 30, 2023, a total of 4,415 m (14,485 ft.) were drilled in 56 holes, with assay results for 19 holes released on May 17, 2023. Assay results for an additional 14 holes was released on July 18, 2023 (see Subsequent to Q2 2023). Assay results for the remaining drill holes are pending.
On April 3, 2023, and on May 4, 2023, the Company disclosed assay results from an aggregate of 50 diamond drilling holes from the 2022 underground exploration program at Trixie. On June 27, 2023, the Company also released underground sampling results from its ongoing 2023 exploration program at Trixie.
The Company is currently working on an updated MRE for the Trixie deposit to incorporate the new 2023 drilling results and the remaining 2022 drilling that was not included in the Tintic Technical Report (as defined herein) published on January 27, 2023 (with an effective date of January 10, 2023), due to assay lab delays. This new MRE is expected to be completed once the 2023 drilling program has concluded and all assay results have been received.
An initial regional surface diamond drilling campaign to test for copper-gold-molybdenum porphyry mineralization potential, namely in the Big Hill area, is anticipated to commence in the following months. Subsequent to quarter end, a diamond drill rig from Major Drilling America of Salt Lake City, Utah, arrived at site in preparation of the contemplated surface drill campaign (see Figure 1).
Data compilation from historic mines in the area is ongoing and anticipated to generate additional exploration drill targets on the greater Tintic Project property.

Cariboo Gold Project – British Columbia, Canada (100%-owned)

On May 8, 2023, the Company announced the signing of two landmark permitting agreements, the Process Charter and the Joint Information Requirements Table, reaffirming the multilateral support of and commitment by the various levels of the Government of British Columbia ("BC") to advance the approval process of the Cariboo Gold Project. The Company also executed several project electrification initiatives in partnership with BC Hydro's CleanBC Industry Fund and the CleanBC Facilities Electrification Fund, which are important steps in supporting the Company's efforts in reducing the carbon footprint of the Cariboo Gold Project.
The Company anticipates that the potential development of Cariboo may provide a basis for progress towards the establishment of a broader mining district camp, including development of multiple deposits over several trends totalling approximately 80 km of mineralization. For further information regarding Cariboo and the Cariboo Feasibility Study refer to Technical Reports.
The Company anticipates receiving the Environmental Assessment Certificate in Q3 2023 and permits by the end of Q1 2024, targets which are aligned with the timelines established in the Process Charter.

San Antonio Gold Project – Sonora State, Mexico (100%-owned)

As of June 30, 2023, the Company sold a total of 12,788 net ounces of gold (gross 14,072 ounces) from the San Antonio heap leach pad since commencing processing of stockpile inventory in Q1 2022. A total of 1,244 net ounces of gold was sold in Q2 2023 (gross 1,008 ounces).
On April 29, 2023, Mexico's Senate approved a wide-ranging reform of laws governing the mining industry, including a requirement that companies pay a percentage of profits to various stakeholders. The new mining law reduces the maximum length of concessions from 50 to 30 years, and may allow authorities to cancel concessions if no work is done on them within two years. The Company is closely monitoring the situation and will continue to assess the potential impacts on its Mexican assets.
The Company will continue its efforts on the remaining stockpile processing, which is expected to be completed in Q3 2023. The Company awaits next steps from the government of Mexico with respect to the permitting process.

SUBSEQUENT TO Q2 2023

On July 18, 2023, the Company disclosed assay results from 14 diamond drilling holes and chip sampling results from new development areas from its ongoing 2023 underground infill and exploration program at Trixie. Select assay results highlights included (see news release dated July 18, 2023):
65.00 grams per tonne ("g/t") gold ("Au") and 344.39 g/t silver ("Ag") over 4.57 m in hole TRXU-DD-23-026 (1.90 troy ounces per short ton ("oz/t") Au and 10.04 oz/t Ag over 15 ft.).

On July 6, 2023, the Company announced that in accordance with the terms of the Company's previously-completed acquisition in May 2022 of a 100% ownership interest in the Tintic Project, it had satisfied the first of five deferred payments to the sellers. Deferred consideration of US$2,500,000 was satisfied by an amount of US$250,000 ($334,400) paid in cash in June 2023 and an amount of US$2,250,000 ($2,986,425) settled by the issuance of 454,026 common shares on July 6, 2023."

(NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce chip sampling results from new development areas as part of its ongoing exploration program at its 100%-owned Trixie test mine ("Trixie"), within the Company's wider Tintic Project ("Tintic" or the "Tintic Project"), located in the historic East Tintic Mining District in central Utah, U.S.A.

Chris Lodder, President of Osisko Development, commented, "The new developments at Trixie to the north continue to show mineralization and high-grade gold samples within the T2 and T4 zones toward a mineralizing fault structure, the Trixie Fault. We will continue to explore this area to the north toward the historical 756 ore shoot. This area was previously developed over a 275-metre strike length down to vertical depths of 300 meters and had an average grade of 6-8 g/t gold, while primarily mined for flux. This area remains open in all directions. We are also pleased to announce the near completion of the new decline at Trixie, which is expected to break through in the next few weeks. This is a milestone accomplishment for our team that will improve access for deeper and nearby exploration as well as any future potential production at Trixie or nearby target areas."

CHIP SAMPLE RESULTS SUMMARY

Chip samples were collected from the T2 structure and T4 stockwork on the 625 ft level and along new development at the Trixie decline (See Figures 2 and 3).
Sampling on the 625 ft-level focussed on development to the north towards the Trixie fault and the 756 vein.
Samples collected near the Trixie decline focussed on a new crosscut west towards the T2 structure at the 600 ft-level.
Approximately 95% of the 1,390 m (4,550 ft.) Trixie portal and underground decline ramp has been completed to date, with approximately 250 ft. remaining to breakthrough. The Company anticipates completion of the decline ramp to the main 625 ft-level in Q3 2023.
The sampling and drilling results provide support that our target areas to the north of Trixie and to the south down plunge of the T2 structure are mineralized and warrant further follow-up exploration drilling and sampling.

These sampling results will provide valuable data to improve our understanding and the confidence level of the mineralized zones defined in the area of the Trixie MRE (as defined herein) and support a future mineral resource estimate ("MRE") update.
The Company is currently working on an updated MRE for the Trixie deposit to incorporate the new 2023 drilling results and the remaining 2022 drilling that was not included in the Tintic Technical Report (as defined herein) published on January 27, 2023 (with an effective date of January 10, 2023), due to assay lab delays. This new MRE is expected to be completed once the 2023 drilling program has concluded and all assay results have been received.

Face Sampling Methodology

As most structures at Trixie are steeply dipping to the east or west, current sampling procedures are designed to sample the structure. Chip samples are collected and do not exceed 1.0 m (3 ft.) in length. The face is washed for safety, and for better identification of mineralization, alteration and structures. The hanging wall and footwall of the structures are marked up on the face and back, samples intervals are marked up and follow lithological contacts.

Samples are collected in feet and assays are reported in grams per tonne and troy ounce per short ton gold and silver. Conversions to metric and imperial measurements are rounded to two decimal places.

About Trixie

The Trixie test mine is one of several gold and base metal targets within the larger Tintic Project consisting of >17,000 acres of patented mining claims and mineral leases within the historic East Tintic Mining District of Central Utah, U.S.A. The T2 and T4 structures at Trixie show multi-ounce gold grades associated with high sulphidation epithermal mineralization, structurally controlled and hosted within quartzites. The T2 structure mineralization consists of native Au, and rare Au-Ag – rich telluride minerals with quartz. The T4 is a mineralized stockwork zone is located in the hanging wall of the T2 and is comprised of Au-Ag rich mineralization in host rock quartzite with quartz-barite-sulphosalt stockwork veining. Mineralization reports consistent multi-ounce gold grades along the entire strike length.

"MONTRÉAL, Oct. 10, 2023 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce that it has received an Environmental Assessment ("EA") Certificate for the Company's 100%-owned Cariboo Gold Project ("Cariboo" or the "Project") located in central British Columbia ("BC"), Canada.

The EA Certificate was granted by the Environmental Assessment Office of the Province of British Columbia ("EAO") and is supported by approval decisions from The Honourable George Heyman, Minister of Environment and Climate Change Strategy and The Honourable Josie Osbourne, Minister of Energy, Mines and Low Carbon Innovation. Receipt of the EA Certificate successfully concludes the EA process for the Project, which was launched in October 2019 (see Figure 1).

Sean Roosen, Chairman and CEO, commented, "We are proud to be the first project, mining or otherwise, in BC to receive an EA Certificate under the new streamlined EA framework of the Environmental Assessment Act, 2018, and we commend the EAO and the Government of BC for establishing this robust regulatory framework. Receipt of the EA certificate marks a major, positive milestone for the Cariboo Gold Project. We continue to be encouraged by the steady progress made to de-risk the Project, bringing it closer to shovel ready status. As we all know, development projects fall into two buckets – those with permits and those without permits – and we are keen to unlock significant value at the Cariboo Gold Project as we move along that path. I would like to thank our team for their dedication and tireless efforts in shepherding the Project through this rigorous EA process that started in 2019. Together with our partners and stakeholders, we remain committed to developing a modern, safe and sustainable operation that benefits all."

Lhtako Dené Nation Chief and Council remarked, "We are extremely proud of the relationship fostered with Osisko Development on the Cariboo Gold Project over the past several years. This relationship has been reciprocal from day one, and Lhtako Chief and Council look forward to many more years of partnership and collaboration. Recently, Lhtako and Osisko engaged in the EA process for the Company's Cariboo Gold Project. Environmental risks, as well as wildlife concerns, are top priorities for both Osisko Development and the Lhtako Dené Nation. With the EA process now complete, we are quite confident that all of our areas of concern have been addressed and mitigated throughout this process."

Chief Willie Sellars of the Williams Lake First Nation ("WLFN") noted, "This decision reflects the importance of meaningful collaboration between industry and Indigenous communities. This is a significant milestone in advancing sustainable mining practices within our traditional territory, particularly the QR Mill Site near Likely, BC. WLFN remains committed to monitoring the Project's progress to ensure it upholds the highest environmental and cultural standards. We look forward to continuing our positive partnership with Osisko Development."

Chief Rhonda Phillips of the Xatśūll First Nation added, "Xatśūll First Nation would like to congratulate the success of Osisko Development in being awarded approval for the Cariboo Gold Mine Project. We acknowledge the hard work, dedication and collaboration that went into getting the Project to this point. Working together to ensure resource development projects meet environmental sustainability targets and improve the socio-economic wellbeing of our communities is a high priority for Xatśūll First Nation. We look forward to continuing work with Osisko and other stakeholders to advance this Project."

The EA Certificate is the first step in the permitting process of the Cariboo Gold Project. As previously disclosed on May 8, 2023, the Company announced the signing of two landmark permitting agreements – the Process Charter and the Joint Information Requirements Table – which establish a defined regulatory process timeline and outline all agreed upon information requirements to support a robust permit application for submission.

A Joint Permit Application for the BC Mines Act / Environmental Management Act is in process. The Company anticipates receiving the permits in Q1 2024."
