Osisko Announces Preliminary Q3 2023 Deliveries, Along With Record Quarterly Revenues and Cash Margin and Provides Portfolio Updates

MONTRÉAL, Oct. 11, 2023 (GLOBE NEWSWIRE) -- Osisko Gold Royalties Ltd (the “Corporation” or “Osisko”) (OR: TSX & NYSE) is pleased to provide an update on its third quarter 2023 deliveries, revenues, cash margin and recent asset advancements. All monetary amounts included in this report are expressed in Canadian dollars, unless otherwise noted.

PRELIMINARY Q3 2023 RESULTS

Osisko earned approximately 23,292 attributable gold equivalent ounces1 (“GEOs”) in the third quarter of 2023, including 1,386 GEOs earned from the recently acquired CSA silver stream.

Osisko recorded preliminary revenues from royalties and streams of $62.1 million during the third quarter and preliminary cost of sales (excluding depletion) of $4.4 million, resulting in a record quarterly cash margin2 of approximately $57.7 million (or 93%).

Osisko’s cash balance was relatively stable at the end of the third quarter at approximately $70.8 million, resulting in a net debt position of approximately $244.6 million as at September 30, 2023, representing an improvement of $5.0 million despite additional investments in royalties completed during the quarter.

Paul Martin, Interim CEO of Osisko, commented: “Osisko delivered a solid quarter of GEOs earned, along with record revenues and cash margin in Q3 despite challenges faced by some of our key operating partners over the past several months. These include the forest fires in northern Canada, other ongoing ramp-up issues, and a notable sharp decline in rough diamond prices. While we anticipate improved quarter-over-quarter performance at several of our core producing assets, Renard will continue to be impacted by weak rough diamond prices and, as a result, Osisko is assuming no reportable GEOs from Renard in Q4. As such, we now are guiding towards the low end of our GEO delivery guidance for 2023.”

Osisko will provide full production and financial details with the release of its third quarter 2023 results after market close on Wednesday, November 8th, 2023 followed by a conference call and webcast on Thursday, November 9th at 10am ET. More details are provided at the end of this release.

PORTFOLIO UPDATE

Canadian Malartic Complex - Second Quarter Production & Underground Development Updates
(5% Net Smelter Return [“NSR”] royalty on open pit and 3-5% NSR royalty on underground)

On July 26th, Agnico Eagle Mines Limited (“Agnico Eagle”) announced second quarter 2023 gold production from the Canadian Malartic Complex (“Canadian Malartic”) of 177,755 ounces. The majority of the gold produced during the period was sourced from the Barnat pit, with the Canadian Malartic pit having finally been depleted in the second quarter of 2023. Preparations for in-pit tailings disposal have commenced, which is expected to start in the second half of 2024. Notably, gold production from the Odyssey mine via the ramp from Odyssey South in the second quarter of 2023 totaled 6,747 ounces. On June 28th Canadian Malartic reached a milestone by pouring its seven millionth gold ounce since achieving commercial production in 2011. Osisko would like to extend its congratulations to Agnico and the Canadian Malartic team on this remarkable achievement.

In addition to the results of an internal study on the Odyssey Underground mine released on June 20th (see Figure 1, below), on July 26th, Agnico Eagle also provided key highlights of the 2023 Odyssey Study and work completed in the second quarter. These include:

• Approximately 60% of the surface construction has been completed with approximately US$429 million spent on construction and development activities through June 30, 2023.
  
  
• As at June 30, 2023, approximately 60 meters of the shaft had been sunk, with approximately 50 meters of that concrete-lined. Shaft sinking activities increased through the quarter, with the ongoing commissioning of shaft sinking equipment.
  
  
• The commissioning of the paste plant was expected to be completed in the third quarter of 2023, which will facilitate the production ramp-up to the design rate of 3,500 tonnes per day (“tpd”) in 2024.
  
  
• The extraction of the first stope at Odyssey South in the second quarter of 2023 has shown positive reconciliation with respect to tonnes and gold grade, reflecting the potential contribution from internal zones (previously unclassified mineralized zones within the porphyry, currently being infill drilled and defined). Agnico Eagle continues drilling to better identify the internal zones that have the potential to improve the production profile at Odyssey South. The production levels below level 36 have been redesigned to capture the potential mining recovery of these zones.
  
  
• The next phase of surface construction and underground mine development is on schedule, with a focus on initiating production from East Gouldie via ramp and shaft in 2027. The main hoist building is expected to be completed in 2025, while the ore silo, the second phase of the paste plant, the shaft sinking and the first loading pocket at mid shaft are expected to be completed in 2027.

The recently completed (second quarter of 2023) internal study on Odyssey Underground was previously highlighted by the fact that Agnico Eagle’s confidence in the overall mine plan had improved with approximately 53% of mineable gold ounces now categorized as Indicated mineral resources compared to approximately 5% in the internal study completed in 2020. Further to this, the larger mineable mineral resource extended the mine life to 2042 and increased the forecast gold production for the Odyssey mine by 23%, or 1.7 million ounces of gold, compared to the 2020 Odyssey Study.

On the exploration front, up to 16 drill rigs were active on the Canadian Malartic property during the second quarter and 32,285 meters of drilling were completed. Drilling targeted several areas that are part of the Odyssey mine, including the infill of the East Gouldie deposit from surface, and of the Odyssey South and Odyssey internal zones from the exploration ramp.

Exploration drilling also continued to investigate the broader East Gouldie mineralized zone and extended the zone laterally to the east and to the west. Regional exploration drilling totaled 3,000 meters during the second quarter, with work resuming on the Rand Malartic property to test the extension of the Odyssey mine's different zones.

CSA - Exploration and Operations Update
(100% Silver Stream and 3% Copper Stream [Cu Stream Commences June 2024])

On September 11th, Metals Acquisition Limited (“MAC”) reported July and August 2023 production (the first two full months of MAC’s ownership) of 7,294 tonnes of copper from the CSA Mine (“CSA”). Mill throughput in July 2023 of 118kt of ore was a record and the focus is on increasing ore from the mine to fill the excess plant capacity.

In addition, and also in the third quarter, on July 31st and September 11th respectively, MAC announced the results from the ongoing resource infill and near mine exploration drill programs at CSA. These results included:

• 50.4 meters @ 8.9% Cu and 36 g/t Ag, from 170.6 meters in UDD20134
• 25.5 meters @ 12.7% Cu and 55 g/t Ag, from 150.5 meters in UDD20128
• 20.7 meters @ 14.4% Cu and 61 g/t Ag, from 150.5 meters in UDD20147A
• 28.7 meters @ 10.6% Cu and 41 g/t Ag, from 179.8 meters in UDD20140
• 21.5 meters @ 7.7% Cu and 32 g/t Ag, from 139.7 meters in UDD21049
  

Drilling has continued to demonstrate the continuity and high-grade nature of the CSA ore bodies. These holes are predominately across the QTSN and QTSC deposits and highlighted potential lode extensions down dip and along section and opportunities for thicker lode interpretations. All drill results are from drilling that has been completed after the December 2022 Mineral Resource Estimate and will be incorporated into the 2023 Mineral Resource Estimate.

Mantos Blancos - Phase 1 Expansion Ramp Up Details
(100% Silver Stream)

On August 2nd, Capstone Copper Corp. (“Capstone”) discussed its progress on the ramp up of the Phase I debottlenecking project at the Mantos Blancos mine ("Mantos Blancos"). Capstone has experienced lower mill throughput of late as a result of mill downtime caused by unplanned repair and maintenance of a mill lubrication system, tailings dewatering challenges due to presence of clays in the top benches of Phase 20, and other challenges related to the integration of pre-existing and new equipment. A plan to address the plant stability is underway that includes improved maintenance and optimization of the concentrator. Capstone expects Mantos Blancos to be consistently delivering higher throughput rates in the second half of 2023, and to be fully ramped up to design capacity (~20,000 tpd) by year end.

Capstone is currently evaluating the potential to further increase throughput of the Mantos Blancos sulphide concentrator plant from 20,000 tpd to 27,000 tpd using idled mill capacity. The Mantos Blancos Phase II debottlenecking project feasibility study is expected to be released in the second half of 2024.

On September 28th, Capstone announced that the Copper Mark had been awarded to Mantos Blancos, highlighting Capstone’s commitment to responsible operating practices, the environment, employees, local communities and governments. The Copper Mark is a comprehensive assurance framework, developed to ensure that value chain participants demonstrate best practice in responsible production and contribute to the United Nations Sustainable Development Goals.

Eagle - 2023 Guidance Maintained After Solid Third Quarter and Despite Wildfire Interruptions
(5% NSR Royalty)

On October 4th, Victoria Gold (“Victoria”) announced its third quarter production results. The Eagle Gold mine (“Eagle”) produced 41,561 ounces of gold during the period from July 1st to September 30th, 2023. Year-to-date 2023 gold production was 124,749 ounces. Gold production was up by 17% in the first nine months of 2023 compared to the same period in 2022 while third quarter production decreased 17% year-over-year. Both the quarterly decrease year-over-year and the 9-month year-to-date increase are due to a reduction in seasonality as a result of year-round ore stacking on the heap leach pad, a more even distribution of planned maintenance throughout the year and a growing heap leach pad which moderates quarter-over-quarter gold production. The third quarter quarter-over-quarter decrease in grade was due to mine sequencing. Ore and waste mined, ore stacked on the heap leach pad and gold produced were all negatively impacted during the third quarter of 2023 by an approximate two-week evacuation in early August due to wildfire activity.

On September 14th, Victoria announced the first analytical results from the 2023 exploration campaign at the Raven deposit. Raven was the primary focus of the exploration efforts with over 13,200 meters of diamond drilling completed. Highlights include 7.80 g/t Au over 6.0 meters from 235.5 meters, and 3.45 g/t Au over 27.5 meters from 239.0 meters. Victoria anticipates releasing an updated Raven Mineral Resource Estimate (“MRE”) after the completion of the 2023 field season including receipt and analysis of all results.

Éléonore - Back Up and Running After Wildfire Evacuation
(2.2-3.5% NSR Royalty)

During Newmont Corporation’s (“Newmont”) second quarter results conference call held on July 20th, Newmont’s management noted at the time that in the second week of June, the company made the swift and proactive decision to evacuate its workforce and place the Éléonore gold mine (“Éléonore”) on care and maintenance to protect the company’s employees and contractors. On July 20th, Newmont added that it was then safely ramping up production activities as the forest fire threat continued to abate. Along with its second quarter results, Newmont noted that Éléonore produced 48,000 ounces of gold during the period, and that annual production guidance range was still being maintained at 265,000-295,000 ounces of gold.

Island Gold - Expecting Stronger Mining and Milling Rates in Second Half of 2023
(1.38%-3% NSR Royalty)

On July 26th, Alamos Gold Inc. (“Alamos”) reported that Island Gold mine (“Island Gold”) produced 30,500 ounces of gold in the second quarter of 2023 (vs. 32,900 ounces in the first quarter) reflecting lower tonnes and grades processed. Underground mining rates averaged 1,105 tpd in the second quarter, lower than both annual guidance and the prior year period reflecting unplanned downtime due to smoke from wildfires in Northern Ontario as well as weather related power outages. Stronger mining and milling rates are expected in the second half of the year, the operation therefore remains on track to meet full year production guidance of 120,000-135,000 ounces of gold.

With respect to Island Gold’s Phase 3+ Expansion, total capital expenditures were US$54.7 million in the second quarter with spending through the period focused on shaft site infrastructure, including the hoist house and headframe. The expanded and accelerated mine plan as part of Phase 3+ also transitions a greater proportion of production towards Osisko’s 2% and 3% NSR royalty boundaries earlier in the mine plan, as opposed to the mineral inventory covered by Osisko’s current 1.38% NSR royalty.

A total of US$14 million is budgeted for exploration at Island Gold in 2023. For the past several years, the exploration focus has been on adding high-grade mineral resources at depth in advance of the Phase 3+ Expansion study, primarily through surface directional drilling. The underground exploration drilling program has been expanded from 27,500 meters in 2022 to 45,000 meters in 2023 and is focused on defining new Mineral Reserves and Resources in proximity to existing production horizons and infrastructure including along strike, and in the hanging-wall and footwall. These potential high-grade mineral reserve and resource additions would be low-cost to develop and could be incorporated into the mine plan and mined within the next several years.

Sasa - Steady Third Quarter Operations + Progress on New Infrastructure
(100% Silver Stream)

On October 10th, Central Asia Metals plc (“CAML”) provided a third quarter operations update from its Sasa zinc-lead mine in North Macedonia. During the period, 10,249 tonnes of concentrate containing 50.0% zinc and 9,919 tonnes of concentrate containing 71.0% lead were produced. Payable base metal in concentrate sales for the third quarter 2023 were 4,097 tonnes of zinc and 7,252 tonnes of lead. Sasa noted that it sold 95,044 ounces of payable silver to Osisko Gold Royalties, in accordance with its streaming agreement.

Phase two of the Central Decline development at depths beneath the 910 metre level is underway and, as at September 30th, the decline had been developed down to 860 metres. While Sasa awaits a component to enable testing of cemented backfill, mining on the 800 metre level that has been prepared for paste fill mining operations has now commenced. Construction of the dry stack tailings plant project has commenced, as has land clearance for the dry stack tailings landform.

Seabee - Update
(3% NSR Royalty)

On August 2nd, SSR Mining Inc.’s (“SSR Mining”) announced that in the second quarter, underground mining rates rebounded, averaging more than 1,300 tpd reflecting the ongoing success of continuous improvement initiatives at the site. Processed grades improved in July, resulting in 8,000 ounces of gold produced during the month. SSR Mining noted that after the strong July, Seabee is positioned for a stronger second half of 2023.

SSR Mining continues to advance its near-mine exploration at Seabee, prioritizing mineral resource conversion activities to ensure growth and mine life extensions in the future.

Lamaque - Update
(1% NSR Royalty)

On October 1st, Eldorado Gold Corporation (“Eldorado”) announced that Lamaque produced 42,691 ounces of gold in the third quarter. Third quarter production increased slightly over the first and second quarter. Production was impacted by slower than expected development in the underground as a result of suspended shifts in the second quarter due to the wildfires in the region. In the fourth quarter, Eldorado expects to continue to push development, allowing access to higher grade stopes from the C4 zone.

The second half of the year is expected to be stronger as both processing rates and grade increase. In 2023, production guidance at Lamaque is forecasted to be 170,000 to 180,000 ounces of gold.

Eldorado also highlighted that exploration results at Ormaque continue to demonstrate the potential to increase resources. Partial results from resource conversion drilling will be incorporated in a resource update later in 2023 and an inaugural reserve on Ormaque in 2024.

Gibraltar - Throughput and Production Improve Quarter-Over-Quarter
(87.5% Silver Stream)

On October 4th, Taseko Mines Limited (“Taseko”) announced that during the third quarter of 2023, Gibraltar produced 35 million pounds of copper and 369,000 pounds of molybdenum. The 25% quarter-over-quarter increase in copper production was a result of higher grades, improved recoveries and increased mill throughput. Mining in the Gibraltar pit is progressing on plan and the lower benches are providing the ore quality the company had been expecting. Mining operations are now well established in the lower benches of the Gibraltar pit, which have higher grades and larger, more consistent ore zones. Notably in June and July, Taseko benefited from the softer ore in the Gibraltar pit, and mill throughput averaged well above nameplate capacity. The Gibraltar pit will be the sole source of ore for the remainder of 2023, resulting in the higher production already seen in the third quarter; this is expected to continue through the final quarter of the year.

Pan - Ongoing Exploration Success
(4% NSR Royalty)

On October 10th, Calibre Mining Corp. (“Calibre”) reported third quarter gold production from Pan of 9,729 ounces, down slightly, but effectively in-line with Calibre’s output in the second quarter. Full year 2023 production guidance from the mine was maintained at 40,000-45,000 ounces of gold.

On August 1st, Calibre announced additional near surface, resource expansion assay results from its 2023 drill program at Pan. Results at the Dynamite North and Palomino targets located immediately north and south of the current open pit operation, respectively, continue to expand zones with grades higher than Pan’s stated mineral resource grade of 0.4 g/t Au. Currently a small amount of material at Palomino exists in Inferred resources, and recent results come from targets that immediately surround the current open pit operations. The potential now exists to materially increase resource ounces, grade and confidence south of the Pan mine and the Palomino deposit remains open to the southeast and at shallow depths. Some highlight intercepts include 1.23 g/t Au over 38.1 meters, 2.56 g/t Au over 10.7 meters and 1.13 g/t Au over 22.9 meters. All drill targets are located near-surface in oxidized limestone. Given the proximity to the current open pit, and the fact that Palomino is within the permitted area, Calibre has indicated they could start mining at Palomino as early as 2024.

Renard - Update
(9.6% Diamond Stream)

After a two-week interruption due to forest fires near the mine site, Stornoway Diamonds (Canada) Inc. resumed mining operations on July 1st and the diamond recovery plant restarted on July 4th. As a result of the temporary evacuation, there has been a moderate impact on deliveries from Renard in the third quarter of 2023. More importantly, the diamond market has seen continued softening over the second and third quarter due to low polished stone demand in both the United States and Chinese markets. Further exacerbating the situation for Renard, the Indian diamond industry has called for a voluntary halt on all rough diamond imports for a two-month period (October and November) to alleviate pressures faced by manufacturers holding high levels of polished inventory. Given these headwinds, Renard’s equity shareholders are currently exploring a variety of alternatives which will include providing funding for near-term working capital shortfalls at the operation. Taking into account all of the above, Osisko now expects Renard will provide no reportable GEOs under its diamond stream for at least the remainder of the year.

Corvette - Maiden CV5 MRE Delivers on Expectations + Subsequent Strategic Investment by Albemarle (2% NSR Royalty on Lithium)

On July 30th, Patriot Battery Metals Inc. (“Patriot”) announced the inaugural MRE for the CV5 Spodumene Pegmatite at its wholly owned Corvette Property, located in the Eeyou Istchee James Bay region of Québec. The CV5 spodumene pegmatite is located approximately 13.5 kilometers south of the regional and all‑weather Trans-Taiga Road and powerline infrastructure corridor, and within 50 kilometers of the La-Grande 4 (LG4) hydroelectric dam complex.

The MRE at CV5 has established it as the largest lithium pegmatite mineral resource in the Americas, returning 109.2 million tonnes at 1.42% Lithium Oxide (“Li2O”) and 160 parts per million (“ppm”) Tantalum Pentoxide of Inferred resources, at a cut-off grade of 0.40% Li2O, for a total of 3,835,000 tonnes contained lithium carbonate equivalent. Additionally, and as reported by Patriot, the resource and geological modelling has outlined significant potential for growth at CV5, which remains open at both ends along strike, and to depth along a significant portion of its length.

Osisko holds a sliding scale NSR royalty of 1.5-3.5% on precious metals, and 2.0% on all other products, including Lithium, at Corvette. Osisko estimates that a large majority (~80-95%) of the CV5 MRE falls on its 2.0% Lithium NSR royalty area (see Figure 3 below). The inaugural MRE includes only the CV5 Spodumene Pegmatite, and therefore does not include any of the other known spodumene pegmatite clusters on the Property – CV4, CV8, CV9, CV10, CV12, and CV13; some of which are covered Osisko’s royalty.

On July 31st, Patriot announced a $109 million strategic equity investment (the “Strategic Investment”) by Albemarle Corporation (“Albemarle”). Upon closing of the Strategic Investment, Albemarle will own approximately 4.9% of Patriot’s issued and outstanding common shares on a fully-diluted in-the-money basis, or 6.4% on a non-diluted, issued and outstanding basis. The proceeds from the Strategic Investment will be used to accelerate the development activities at Corvette and for general corporate purposes. Osisko believes the strategic investment serves to further underpin the quality of this asset on a global scale.

On September 24th, Patriot announced drill results confirming extension of the CV5 spodumene pegmatite by 0.65 kilometers since the MRE to attain a total length of 4.35 kilometers. This is highlighted by several drill intersections of over 90 meters of cumulative core length hosting spodumene bearing pegmatite. Patriot also announced an initial drill campaign on the CV9 pegmatite cluster.

Hermosa - Taylor Development Update
(1% NSR Royalty on Taylor and Peake)

On August 23rd, along with its financial results and outlook for the year ended June 30th, 2023, South32 Ltd. (“South32”) provided additional information with respect to its activity and timeline at the Hermosa Taylor zinc-lead-silver development project. South32 highlighted that a final Feasibility Study and final investment decision (FID) is still expected in 2023. South32 is currently optimizing the mine development schedule in accordance with FAST-41 permitting. To qualify for the FAST-41 process, complex critical infrastructure projects must meet rigorous criteria to demonstrate benefit to the United States. Further to this, the company is evaluating the opportunity for an extended mine life of up to ~30 years, at a nameplate processing capacity of 4.3 million tonnes per annum.

South32 noted that it was commissioning a second water treatment plant to support orebody dewatering, enabling access to the Taylor and Clark deposits. Dewatering wells to support shaft sinking are currently under construction, while the pre-sink shaft and initial site infrastructure development is already underway. Finally, on the exploration front, South32 is continuing to drill the Peake Prospect (see Figure 4, below) following high-grade copper results. Recent Peake drilling returned the best copper results to date, with 139 meters at 2.49% copper equivalent (“CuEq”) including 58.2 meters at 3.84% CuEq.

Costa Fuego - Project Footprint Set to Grow & Updated Resource Drilling Commences
(1% NSR Royalty on Copper and 3% NSR Royalty on Gold)

On August 28th, Hot Chili Limited’s (“Hot Chili”) announced that it had entered into a binding letter of intent with Bastion Minerals Limited (“Bastion”) for the grant to Hot Chili of an option to acquire 100% of Bastion’s Cometa Project in Chile (“Cometa”), located near Hot Chili’s Costa Fuego Copper-Gold Project (“Costa Fuego”) in the coastal range of the Atacama Region, Chile. Cometa consists of exploration and mining concessions covering approximately 56 square kilometers in area located approximately 15 kilometers southeast of Costa Fuego’s planned operating center and contiguous with Hot Chili’s landholdings in the region. This option is another step in Hot Chili’s consolidation strategy for the Costa Fuego copper project.

On August 3rd, Hot Chili announced that drilling has re-commenced across the western extension of the Cortadera porphyry resource. Drilling operations have been underway since late July with one reverse circulation rig in operation and further diamond drill rigs to be added as Hot Chili ramps up its fully funded 30,000-meter expansion drilling program across Costa Fuego. An updated resource is scheduled for late 2023 and will serve as the basis for a Pre-Feasibility Study, scheduled for completion in the second half of 2024.

Costa Fuego is one of the world’s largest undeveloped copper projects, not currently controlled by a major mining company. It hosts an NI 43-101 Indicated resource including both the open pit and underground portions of the Cortadera and Productora deposits, of 725 million tonnes grading 0.47% CuEq, grading 0.38% copper, 0.11 g/t Au, 0.45 g/t Ag and 93 ppm Molybdenum and an Inferred resource of 202 million tonnes grading 0.30% Cu and 0.06 g/t Au. The June 2023 Preliminary Economic Assessment (“PEA”) projects a 16-year mine life with average annual production of 95,000 tonnes of copper and 49,000 ounces of gold in the first 14 years. Costa Fuego is situated at low altitude and is near all key infrastructure requirements.

Osisko Development - Asset Updates for Cariboo, Trixie/Tintic and San Antonio
(5% NSR Royalty on Cariboo)
(2.5% Metals Stream on Tintic)
(15% Gold-Silver Stream on San Antonio)

On October 10th, Osisko Development Corp. (“Osisko Development”) announced that it received an Environmental Assessment Certificate for the Cariboo Gold Project. A Joint Permit Application for the BC Mines Act / Environmental Management Act is in process and Osisko Development anticipates receiving permits in the first quarter of 2024.

On August 8th, along with its second quarter results, Osisko Development announced that approximately 85% of the of the Trixie portal and underground decline ramp has been completed as at June 30, 2023. Osisko Development anticipates completion of the decline ramp to the main 625 feet underground level in the second half of 2023, which is expected to significantly improve underground access for exploration drilling. Subsequent to quarter end, on September 13, Osisko Development noted that the decline was approximately 95% complete.

At the Trixie test mine ("Trixie"), located within the wider Tintic Project in central Utah, the target to ramp up processing capacity to 500 short tons per day remains subject to completion of required mine and mill infrastructure upgrades, an updated MRE and ongoing technical work. A new MRE is expected to be completed once the 2023 exploration drilling program has concluded and all assay results have been received. Small-batch VAT leaching recommenced during the second quarter as Osisko Development advanced ongoing technical work in connection with the required mine and mill infrastructure upgrades. 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 H2 2023.

At San Antonio, Osisko Development will continue its efforts on the remaining stockpile processing, which was expected to be completed in the third quarter. The company awaits next steps from the government of Mexico with respect to the permitting process.

Cascabel – SolGold Inks Exploitation Agreement with Government of Ecuador
(0.6% NSR Royalty)

On July 20th, SolGold PLC (“SolGold”) announced that it had completed the contractual negotiations and agreed upon a term sheet in preparation for the execution of the Exploitation Agreement for the Cascabel Project, its flagship copper-gold project in Ecuador. Key contract terms include:

• SolGold, through its wholly owned subsidiary in Ecuador, Exploraciones Novomining S.A. (“Mining Concessionaire”), has negotiated the right to develop the Cascabel Project and produce copper, gold, and silver from the contract area for 33 years, which may be renewed.
  
  
• The company and the Government of Ecuador have agreed to an advance royalty payment totalling US$75 million, with US$25 million due upon the concentrator construction start date. The remaining two payments, each of US$25 million, will be made on the first and second anniversary, respectively, from the date of the first payment. The advance royalty will be deductible against the Government Royalty.
  
  
• One of the key economic assumptions is that the company expects a reduced corporate income tax rate of 20% (previously 25%) during the Project’s life once the Government of Ecuador approves the amendment of the Investment Protection Agreement. Based on this reduced corporate income tax rate, the Mining Concessionaire, the State, and SolGold have agreed to a variable royalty on net smelter revenues in accordance with Ecuadorian Mining Law. The applicable royalty rate follows the progressivity criteria stated in the Mining Law, stipulating a variable percentage rate from 3% to 8%.
  

According to the Mining Law in Ecuador, 60% of the revenues from the royalties collected by the government will be allocated to productive and sustainable projects through the municipal governments and parish councils of the communities of the Cascabel Project. The company expects these funds to make an important contribution to local development.

White Pine North / Copperwood - New Investment Partner and Copperwood Secures Funding to Advance (1.5% NSR Royalty on Copper and 11.5% NSR Royalty on Silver)

On July 24th, Highland Copper Company Inc. (“Highland”) announced the results of the PEA and Mineral Resource Estimate for the White Pine North project (“White Pine North”) in Michigan, USA. Simultaneously, Highland also introduced Kinterra Copper USA LLC (“Kinterra”) as a joint venture (“JV”) partner on the project. Kinterra will bring additional financial and technical strength required to progress the project through to development. Kinterra has made a cash payment of US$30 million to Highland for a 66% stake in the White Pine North project. Kinterra and Highland, as JV partners, have agreed on a further US$30 million investment in the project to be funded by Kinterra. This consists of US$20 million representing Kinterra’s 66% pro rata expenditure, as well as a US$10 million unsecured loan to fund Highland’s pro rata expenditure. The initial US$30 million proceeds from the joint venture arrangement allow Highland to initiate early site works at its fully-permitted 100%-owned Copperwood project, where Highland is focused on advancing to development and production.

Through the period leading up to a construction decision at Copperwood, and through 2024, Highland plans to consider additional value creation opportunities relative to the Copperwood Feasibility Study, particularly infill drilling and potential life of mine extensions. A significant opportunity exists to convert Inferred resources into Measured and Indicated resources.

Highlights from the announced White Pine North PEA are as follows:

• Indicated mineral resource containing 3.5 billion pounds of copper (150.7 million tonnes at 1.05% Cu) and 65.5 million ounces of silver (13.5 g/t Ag)
• Inferred mineral resource containing 2.2 billion pounds of copper (96.4 million tonnes at 1.03% Cu) and 27.8 million ounces of silver (9.0 g/t Ag)
• Mine life of 21.8 years, including 21 months of ramp-up, with average annual life-of-mine payable copper production of 93.5 million pounds and 1.2 million ounces of silver
  

Osisko currently owns a 1.5% NSR royalty on copper production, and an 11.5% NSR royalty on silver production at both Highland Copper’s Copperwood and White Pine projects. At Osisko’s election, the silver royalty percentage may be increased to 100% on Copperwood and White Pine for a payment of US$23 million.

Q3 2023 RESULTS CONFERENCE AND WEBCAST CALL DETAILS

Osisko provides notice of third quarter 2023 results and webcast and conference call details.

Notes:

The figures presented in this press release, including revenues and costs of sales, have not been audited and are subject to change. As the Corporation has not yet finished its quarter-end procedures, the anticipated financial information presented in this press release is preliminary, subject to quarter-end adjustments, and may change materially.

(1) Gold Equivalent Ounces

GEOs are calculated on a quarterly basis and include royalties, streams and offtakes. Silver earned from royalty and stream agreements are converted to gold equivalent ounces by multiplying the silver ounces earned by the average silver price for the period and dividing by the average gold price for the period. Diamonds, other metals and cash royalties are converted into gold equivalent ounces by dividing the associated revenue earned by the average gold price for the period. Offtake agreements are converted using the financial settlement equivalent divided by the average gold price for the period.

Average Metal Prices and Exchange Rate

(i) The London Bullion Market Association’s pm price in U.S. dollars.
(ii) The London Bullion Market Association’s price in U.S. dollars.
(iii) Bank of Canada daily rate.

(2) Non-IFRS Measures

The Corporation has included certain performance measures in this press release that do not have any standardized meaning prescribed by International Financial Reporting Standards (IFRS) including cash margin in dollars and in percentage. The presentation of these non-IFRS measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. As Osisko’s operations are primarily focused on precious metals, the Corporation presents cash margins as it believes that certain investors use this information, together with measures determined in accordance with IFRS, to evaluate the Corporation’s performance in comparison to other companies in the precious metals mining industry who present results on a similar basis. However, other companies may calculate these non-IFRS measures differently.

Cash margin (in dollars) represents revenues less cost of sales (excluding depletion). Cash margin (in percentage) represents the cash margin (in dollars) divided by revenues.
