Osisko Metals Incorporated (the ‘ Company ‘ or ‘ Osisko Metals ‘) ( TSX: OM,OTC:OMZNF ; OTCQX: OMZNF ; FRANKFURT: 0B51 ) is pleased to announce new drill results from the Gaspé Copper Project, located in the Gaspé Peninsula of Eastern Québec.

Osisko Metals CEO Robert Wares commented: ‘These latest results continue to confirm and expand our resource model with several long continuous intersections of copper and molybdenum mineralization in the core of the deposit. The new drilling keeps deepening the deposit and again confirms its southern extension with holes 30-1119 and 30-1124. We are excited about the growth of our project, especially within the context of a fundamental rising metal market where copper spot price is rapidly approaching US$5/lb, silver is at US$47/oz and molybdenum is holding steady at over US$30/lb.’

New analytical results are presented below (see Table 1), including 33 mineralized intercepts from nine new drill holes. Infill intercepts are located inside the 2024 MRE model ( see November 14, 2024 news release ), and are focused on upgrading inferred mineral resources to measured or indicated categories, as applicable. Expansion intercepts are located outside the 2024 MRE model and may potentially lead to additional resources that will be classified appropriately within the next MRE update. Some of the reported intercepts have contiguous shallower infill as well as deeper expansion (noted on Table 1 below as ‘Both’). Maps showing hole locations are available at www.osiskometals.com .

Highlights:

• Drill hole 30-1107
  • 592.0 metres averaging 0.33% Cu (0.46 CuEq) (infill and expansion)
• Drill hole 30-1112
  • 868.5 metres averaging 0.23% Cu (0.30 CuEq) (infill and expansion)
• Drill hole 30-1114
  • 142.1 metres averaging 0.39% Cu (0.47 CuEq) (expansion)
• Drill hole 30-1116
  • 565.5 metres averaging 0.22% Cu (0.29 CuEq) (infill and expansion)
• Drill hole 30-1119
  • 46.4 metres averaging 1.10% Cu (1.25 CuEq) (expansion)
• Drill hole 30-1122
  • 760.5 metres averaging 0.24% Cu (0.30 CuEq) (infill and expansion)
• Drill hole 30-1124
  • 200.5 metres averaging 0.32% Cu (0.37 CuEq) (expansion)
  • 203.2 metres averaging 0.37% Cu (0.39 CuEq) (expansion)

** ‘Both’ indicates drill holes that have contiguous shallower infill as well as deeper expansion intercepts.

Discussion

Drill hole 30-1107, located on top of Copper Mountain near the center of the 2024 MRE model, cut three mineralized intervals including 592.0 metres averaging 0.33 % Cu, 1.68 g/t Ag and 0.032% Mo (which includes 336.6 metres of depth expansion), extending mineralization in this area to a vertical depth of 1003 metres.

Drill hole 30-1112, located on the western flank of Copper Mountain, cut two mineralized intervals including 868.5 metres averaging 0.23 % Cu, 1.45 g/t Ag and 0.019% Mo (which includes 417.0 metres of depth expansion), extending mineralization in this area to a vertical depth of 1119 metres.

Drill hole 30-1113, located on the western margin of the 2024 MRE model, cut multiple intersections of mineralization, 26 to 42 metres thick and distributed in ‘layer cake’ fashion from surface to a vertical depth of 769 metres, confirming the current limit of the 2024 MRE model at this location.

Drill hole 30-1114, located near the eastern margin of the 2024 MRE model, cut multiple intersections of mineralization distributed in ‘layer cake’ fashion from surface to a vertical depth of 950 metres, including 142.1 metres averaging 0.39 % Cu, 1.50 g/t Ag and 0.019% Mo (expansion).

Drill hole 30-1116, located on top of Copper Mountain near the center of the 2024 MRE model, cut six mineralized intervals including 565.5 metres averaging 0.22 % Cu, 1.86 g/t Ag and 0.017% Mo (which includes 96.3 metres of depth expansion), extending mineralization in this area to a vertical depth of 1110 metres.

Drill holes 30-1119 and 30-1124, both located immediately south of the southern margin of the 2024 MRE model, cut multiple intersections of mineralization, including 46.4 metres averaging 1.10 % Cu, 5.08 g/t Ag and 0.032% Mo near and including the E Zone skarn horizon (30-1119) and 203.2 metres averaging 0.37% Cu and 2.81 g/t Ag (30-1124). These intersections extend mineralization to a vertical depth of 619 metres within the southern expansion of the deposit, which remains open towards Needle Mountain East.

Drill hole 30-1121, located 50 metres east of the 2024 MRE model, did not intersect significant mineralization as expected, once again confirming the current eastern limit of the resource model.

Drill hole 30-1122, located on the western flank of Copper Mountain, intersected three mineralized intervals, including 760.5 metres averaging 0.24% Cu, 1.71 g/t Ag and 0.015% Mo (which includes 456.1 metres of depth expansion), extending mineralization in this area to a vertical depth of 1137 metres.

Mineralization at Gaspé Copper is of porphyry copper/skarn type and occurs as disseminations and stockworks of chalcopyrite with pyrite or pyrrhotite and minor bornite and molybdenite. One prograde and at least five retrograde vein/stockwork mineralizing events have been recognized at Copper Mountain, which overprint earlier, bedding replacement skarn and porcellanite-hosted mineralization throughout the Gaspé Copper system. Porcellanite is a historical mining term used to describe bleached, pale green to white potassic-altered hornfels. Subvertical stockwork mineralization dominates at Copper Mountain whereas prograde bedding-parallel mineralization, that is mostly stratigraphically controlled, dominates in the area of lower Copper Mountain, Needle Mountain, Needle East, and Copper Brook. High molybdenum grades (up to 0.5% Mo) were locally obtained in both the C Zone and E Zone skarns away from Copper Mountain.

The 2022 to 2024 Osisko Metals drill programs were focused on defining open-pit resources within the Copper Mountain stockwork mineralization ( see May 6, 2024 MRE press release ). Extending the resource model south of Copper Mountain into the poorly-drilled prograde skarn/porcellanite portion of the system subsequently led to a significantly increased resource, mostly in the Inferred category ( see November 14, 2024 MRE press release ).

The current drill program is designed to convert the November 2024 MRE to Measured and Indicated categories, as well as test the expansion of the system deeper into the stratigraphy and laterally to the south and southwest towards Needle East and Needle Mountain respectively. The November 2024 MRE was limited at depth to the base of the L1 skarn horizon (C Zone), and all mineralized intersections below this horizon represent potential depth extensions to the deposit, to be included in the next scheduled MRE update in Q1 2026.

All holes are being drilled sub-vertically into the altered calcareous stratigraphy which dips 20 to 25 degrees to the north. The L1 (C Zone) the L2 (E Zone) skarn/marble horizons were intersected in most holes, as well as intervening porcellanites that host the bulk of the disseminated copper mineralization.

International Lithium Corp. (TSXV: ILC,OTC:ILHMF) (OTCQB: ILHMF) (FSE: IAH) (the ‘Company’ or ‘ILC’) is pleased to announce, further to its announcement on September 09, 2025, that on October 24, 2025 Lepidico met all the drawdown conditions for completion of its secured loan from ILC and that this has now been increased to the full amount of CAD$ 510,000. Of this loan amount CAD$420,000 earns interest at the rate of 10% p.a.

There were various conditions for the drawdown of the remaining loan, including a key condition now met that, by full drawdown, there would be no debt owed by Lepidico Mauritius or its subsidiaries to its ultimate Australian parent, Lepidico Ltd., which is in liquidation.

ILC now holds without any conditions an option from Lepidico (Canada) Inc. (‘Lepidico Canada’) to buy 100% of the shares of Lepidico (Mauritius) Ltd. (‘Lepidico Mauritius’) on a debt-free basis for consideration of CAD$975,000 plus certain payments in the future that are contingent on and linked to various possible receipts by Lepidico Canada. Lepidico Mauritius in turn owns 80% of Lepidico Chemicals Namibia (Pty) Ltd. (‘Lepidico Namibia’), which owns the Karibib Lithium, Rubidium and Cesium project in Namibia. The actual net amount payable by ILC on option exercise will be the difference between CAD$975,000 payable by ILC for the option exercise and the repayment to ILC of loan principal of CAD$510,000 plus interest accrued to the date of option exercise. The option has been granted until the later of November 30, 2025, and 30 days after the arbitration outcome is known (see below).

It is important to reiterate that there is a possibility that the option may not be exercised, especially if Lepidico Namibia encounters an adverse outcome in an arbitration dispute with the Chinese company Jiangxi Jinhui Lithium Co. Ltd., which involves claims and counterclaims. This arbitration in Singapore is now expected to conclude at any time from now until the end of 2025. Conversely, if the arbitration is resolved positively, ILC and Lepidico Canada have agreed that 30% of the net proceeds after legal and other costs will be retained by the part of the Lepidico group that ILC would be acquiring, with the remaining 70% paid to Lepidico Canada. The deal structure reflects ILC’s reluctance to assume the risk of a negative arbitration award arising from events that occurred seven years ago.

Assuming the transaction goes ahead with ILC exercising its option, the Company would leapfrog, by several years, the development stage of other projects it is interested in, including those in Zimbabwe and:

• have one of the largest rubidium resources in Africa and (per our own research and also using Grok) the largest disclosed rubidium resource in Africa, as well as one of the most extensive rubidium resources in North America through ILC’s existing Raleigh Lake project in Ontario;

• be well-positioned for an upswing in the lithium market; and

• strengthen its stance as one of the leading global players in the rubidium market and a company with some of the most significant cesium interests of any non-Chinese company.

Lepidico’s ownership of Karibib resulted from its 2019 acquisition of TSXV-listed Desert Lion Energy in exchange for shares and other securities valued at that time at AUD$ 22.9 million (approximately CAD$20.7 million). Since acquiring the company in 2019, Lepidico has invested a further AUD$ 12.1 million (approximately CAD$ 10.9 million) in the Karibib project, excluding central group overheads, with a significant portion directed towards drilling, an environmental study and subsequently a Definitive Feasibility Study and a further Resource Estimate both under JORC standards.

The Karibib Project comprises two areas near Karibib, Namibia, with fully permitted mining licences known as Rubicon and Helikon (also in various reports spelled Helicon), along with an Exclusive Prospecting Licence EPL5439 for an adjacent area. Fuller details are as set out in our news release of September 9, 2025.

It is believed, based on published data, that as well as its significant lithium resource, the Karibib project contains the largest (or one of the two largest) rubidium resources of any project in Africa (the others being in Zimbabwe and Zambia). At the same time, the amount of cesium is smaller but nevertheless equal to about one year of global demand. For cesium Sinomine has historically been the largest producer in Africa, and has recently restarted cesium production at its Bikita project in Zimbabwe by extracting pollucite from petalite tailings. Sinomine is also known to have rubidium from the lepidolite at Bikita, but we are not aware of any resource estimate.

If the option is exercised, ILC would, subject to confirming the resource as its own resource (and not a historical resource as it is presently treating it) have the largest known or at least the largest disclosed rubidium resource in Africa. The Company also has extensive rubidium resources in North America through its Raleigh Lake project in Ontario. Please refer to the Company’s ‘The Raleigh Lake Project – NI 43-101 Technical Report PEA’ dated January 18, 2024 by ERM Consultants Canada Ltd. and the seven named QPs in the report.

John Wisbey, Chairman of ILC, stated: ‘This potential acquisition marks a significant advancement for ILC globally – particularly in Southern Africa. With this single transaction for a project that reached the Definitive Feasibility Study stage under JORC in 2020 and was upgraded in 2022, the Company would leapfrog, by several years, the development stage of other projects we are interested in, including those in Zimbabwe.’

‘Assuming the transaction goes ahead with ILC exercising its option, ILC will be well-positioned for an upswing in the lithium market, as well as strengthening its stance as one of the leading global players in the rubidium market and a company with some of the most significant cesium interests of any non-Chinese company.’

About International Lithium Corp.

International Lithium Corp. is a Critical Minerals exploration company with exploration activities in Ontario, Canada, with intentions to expand into Southern Africa. It has projects at various stages, ranging from Definitive Feasibility Study at Rubicon in Namibia (note that ILC currently has an option only and is treating this as historic information at this point and not a current resource for ILC) to Preliminary Economic Assessment at Raleigh Lake (as noted above) to Pre-Drilling at Wolf Ridge. The primary target metals in Canada are lithium, rubidium and copper. There are three projects (two in Ontario and one in Ireland) in which ILC has sold its share but where we stand to receive future payments from either a resource milestone being achieved or from a Net Smelter Royalty. In Namibia the Karibib project contains lithium, rubidium and cesium.

While the world’s politicians are currently divided on the future of the energy market’s historic dependence on oil and gas and on ‘Net Zero’, there is in any scenario an ever increasing and significant demand for electricity driven by AI and data centres, and by a likely unstoppable momentum towards electric vehicles and grid-scale electricity storage. All these contribute to rising demand for lithium and copper as well as other metals. Rubidium is also a valuable critical metal that is strategic for high-precision clocks and for space technology. We have seen the politically driven and increasingly urgent wish by the USA, Canada, EU and other major economies to safeguard their supplies of critical metals and to become more self-sufficient. Our Canadian and Southern African projects, which contain lithium, rubidium, cesium and copper, are strategic in that respect.

Our key mission for the next decade is to generate revenue for our shareholders from lithium and other battery metals, as well as rare metals, while also contributing to the creation of a greener, cleaner planet and less polluted cities.

This includes optimizing the value of our existing projects in Canada as well as finding, exploring and developing projects that have the potential to become world-class deposits. We have announced that we regard Southern Africa as a key strategic target market for ILC and, in addition to Namibia, we have applied for and hope to receive EPOs in Zimbabwe. We hope to make further announcements on the portfolio developments over the next few weeks and months.

The Company’s interests in various projects now consist of the following, and in addition, the Company continues to seek other opportunities:

The Company’s primary strategic focus at this point is on the Raleigh Lake Project, comprising lithium and rubidium, and the Firesteel copper project in Canada, as well as obtaining EPOs and mineral claims in Zimbabwe. The Karibib projects in Namibia, including further development on the EPL there, will become a high focus if ILC exercises its option there.

The Raleigh Lake Project now encompasses 32,900 hectares (329 square kilometres) of mineral claims in Ontario and represents ILC’s most significant project in Canada. To date, drilling has occurred on less than 1,000 hectares of our claims. A Preliminary Economic Assessment was published for ILC’s lithium at Raleigh Lake in December 2023, with a detailed economic analysis of ILC’s separate rubidium resource still pending. Raleigh Lake is 100% owned by ILC, free from any encumbrances and royalties. The Raleigh Lake Project boasts excellent access to roads, rail, and utilities.

A continuing goal has been to remain a well-funded company to turn our aspirations into reality. Following the disposal of the Mariana project in Argentina in 2021, the Mavis Lake project in Canada in 2022, and the Avalonia project in 2025, ILC continues to achieve sufficient inward cash flow to be able to make progress with its exploration projects.

With the increasing demand for high-tech rechargeable batteries used in electric vehicles, electrical storage, and portable electronics, lithium has been designated ‘the new oil’ and is a key part of a green energy, sustainable economy. By positioning itself with projects that have significant resource potential and solid strategic partners, ILC aims to be one of the preferred lithium and rare metals resource developers for investors and to continue building value for its shareholders for the rest of the 2020s, the decade of battery metals.
