International Lithium Corp. (TSXV: ILC,OTC:ILHMF) (OTCQB: ILHMF) (FSE: IAH) (the ‘Company’ or ‘ILC’) is pleased to announce that on September 04, 2025 it acquired 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.

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.

The parties have signed a secured loan agreement whereby ILC lends CAD$510,000 to Lepidico Canada. Of the principal amount, CAD$420,000 accrues interest at 10% per annum. If ILC exercises the option, this loan plus interest will be repayable in full from the option exercise proceeds. The option has been granted until the later of November 30, 2025, and 30 days after the arbitration outcome is known (see below). A total of CAD$285,000 has already been advanced to Lepidico. There are various conditions for the drawdown of the remaining CAD$225,000, including standard regulatory approvals and a key condition that, by drawdown, there will be no debt owed by Lepidico Mauritius or its subsidiaries to its ultimate Australian parent, Lepidico Ltd., which is in liquidation. A condition in the option agreement is that Lepidico Mauritius and its subsidiaries will have no debt owed to other previous Lepidico group companies at the time of option exercise.

It is important to emphasize 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 expected to conclude in September or October 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 concerning events that occurred seven years ago.

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.

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.

A Definitive Feasibility Study (the ‘DFS Report’) was announced on May 28, 2020 by Lepidico Ltd. (a public company then listed on the Australian Securities Exchange) based on JORC Code (2012) Mineral Resources and Ore Reserves estimates for the Rubicon and Helikon deposits. The DFS Report is titled ‘Phase 1 Project – Definitive Feasibility Study Report’, and has a publication date of July 10, 2020. It was produced by Lepidico Ltd. who managed the feasibility study listing around 28 organisations with particular expertise in the specific areas of input as contributors to the DFS Report. The DFS Report and ASX announcements regarding the Karibib project, including resource estimates and other pertinent information to the Karibib project are available on Lepidico’s website: www.lepidico.com.

In Lepidico’s news release dated January 30, 2023 Lepidico announced an overall Karibib Project Mineral Resource update as of 31 December 2022 prepared by Cube Consulting which is detailed in the following table. The numbers in this table (the ‘Historical Estimate’) are subject to various assumptions and parameters which are detailed later in this announcement. The Company is not aware of any more recent estimates.

Although the technical information announced by Lepidico was produced according to the requirements of JORC Code (2012), ILC is treating this information as historical information. The Company does however believe, and this thinking was part of its decision to proceed with the transaction, that the mineral resource estimates are likely to be reliable and relevant firstly since JORC Code (2012) is one of the most widely recognized and respected mineral resource reporting standards globally, and secondly there has been no mining activity since the last resource estimate. ILC has not engaged a ‘Qualified Person’ as defined by NI 43-101 to independently verify or complete sufficient additional work to determine the relevance and reliability of the information. The Company’s QP has not done sufficient work to make the resource current and the Company is not treating the resource as current. Only if the option is exercised would ILC, at its own discretion, complete the further technical work and review and evaluation of the information and data supporting the Lepidico information in the DFS Report and/or the Lepidico mineral resource estimates to bring them to current for ILC under NI 43-101. Mineral resources are not mineral reserves and although Lepidico has reported a Definitive Feasibility Study for the project, there is no guarantee that further work will result in an economic mining scenario.

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. This report was filed on SEDAR+ on 18 January, 2024.

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.’

Babak Vakili Azar, P. Geo., a Qualified Person as defined by NI 43-101 and a consultant to ILC, has reviewed and approved the technical contents of this news release.

Notes on the Historical Estimate mentioned above

The mineral resource estimates presented in the table above (the ‘Historical Estimate’) were documented as subject to the following assumptions and parameters:

• There are multiple effective dates, reflecting work on various hard rock deposits and stockpiles over a four year period by multiple consulting groups.

• Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

• Mineral Resources for hard rock deposits are reported at a block cut-off grade of ≥ 0.15% or 0.20% Li₂O for all oxidation types.

• Mineral Resources for stockpiles, dumps and tailings are reported at a 0.0% Li₂O cut-off grade.

• The analysis suite across the deposits and stockpiles was inconsistent and hence average element reporting across all deposits and stockpiles cannot be completed.

• Different components of the Karibib Project have been reported at different times through different consultancy groups, using different Competent Persons.

• The assumed mining method is by open cut.

• Cost, bulk density and recovery inputs used to report the Mineral Resource have varied over time, and relate to the different effective dates for those individual resources.

• Figures may not add up due to rounding.

The Historical Estimate reports categories of mineral resource using the terms ‘inferred mineral resource’, ‘indicated mineral resource’ and ‘measured mineral resource’ as ascribed under JORC Code (2012). These terms also have specific meanings ascribed to them by the Canadian Institute of Mining, Metallurgy and Petroleum, as the CIM Definition Standards on Mineral Resources and Mineral Reserves adopted by CIM Council, as amended. These standards are generally considered interchangeable in the global mining industry with key differences pertaining to disclosure being that NI 43-101 has more prescriptive requirements for the content of technical reports while JORC allows more flexibility in reporting but requires clear explanation of the basis for estimates.

The Historical Estimate is considered to be the most recent and pertinent technical disclosure regarding the Karibib project that is currently available to the Company. If the Company decides to exercise the option, the Company will review the technical reports utilizing Qualified Persons as defined by NI 43-101 to determine which, if any at all, of the mineral resource estimates require additional work to comply with the CIM Definition Standards on Mineral Resources and Mineral Reserves prior to advancing the project or undertaking the necessary work to upgrade or verify the Historical Estimate as current mineral resources or mineral reserves.

About International Lithium Corp.

International Lithium Corp. has 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.

Lode Gold Resources Inc (TSXV: LOD,OTC:LODFF) (OTCQB: LODFF) (‘LOD.V’ and ‘Lode Gold’) and its wholly owned subsidiary Fremont Gold LLC (‘Freemont’), have successfully completed the transfer of the Mine Safety and Health Administration (‘MSHA’) property MSHA individual identification number (‘MIIN’) for its wholly owned Pine Tree Josephine Mine.

This is a critical step toward reviving one of California’s most historically significant gold operations. Fremont is now in active discussions with prospective partners and investors to align the right technical, operational, and financial resources to bring the Pine Tree Josephine Mine (‘Freemont Mine’) back into production in a safe, sustainable, and profitable manner.

The transfer of the MIIN is a key regulatory milestone which ensures that the Company’s ownership and operational control of the Freemont Mine, a historically productive gold property with significant past production, are fully recognized by MSHA, paving the way for the next stage of its development and reactivation plans.

Upcoming catalysts for Lode at Fremont after this milestone are:

– 2025: channel sampling and drilling to upgrade resources to M&I (Measures and Indicated) based on NI 43-101 standards
– 2026: completion of PFS (Pre-Feasibility Study) engineering and metallurgy studies

About Lode Gold

Lode Gold is an exploration and development company with projects in highly prospective and safe mining jurisdictions in Canada and the United States.

In the United States, the Company is focused on its advanced exploration and development asset, the Fremont Mine in Mariposa, California. It has a recent 2025 NI 43-101 report and compliant Mineral Resource Estimate (‘MRE’) that can be accessed here https://lode-gold.com/project/freemont-gold-usa/

The Fremont Mine was previously mined until operations ceased due to mining prohibitions during WWII when its mining license was suspended. Only 8% of the resource identified in the 2025 MRE has been extracted. The Freemont Mine has exploration upside and mineralization is open at depth (three step-out holes at 1,300 meters hit structure and were mineralized) and on strike. This is a brownfield project with over 43,000 meters drilled, 23 kilometers of underground workings and 14 adits. The project has excellent infrastructure and is close to electricity, water, roads, railhead and port.

Recently, the Company completed an internal scoping study, with a strategic pivot to 100% underground mining. Previously, in March 2023, the Company completed an NI 43-101 Preliminary Economic Assessment (‘PEA’) with an open pit and underground combination mine. The NI 43-101 technical reports are available on the Company’s profile on SEDAR+ (www.sedarplus.ca) and the Company’s website (www.lode-gold.com)

In Canada, its Golden Culvert and WIN projects in Yukon, covering 99.5 square kilometres across a 27-kilometre strike length, are situated in a district-scale, high-grade gold mineralized trend within the southern portion of the Tombstone gold belt. A total of four RIRGS targets have been confirmed on the property. A National Instrument 43-101 technical report has been completed in May, 2024.

In New Brunswick, Lode Gold has created one of the largest land packages with its Acadian Gold JV Co., consisting of an area that spans 445 square kilometres and a 44-kilometre strike. McIntyre Brook covers 111 square kiloimetres and a 17-kilometre strike in the emerging Appalachian/Iapetus gold belt; it is hosted by orogenic rocks of similar age and structure as New Found Gold’s Queensway project. Riley Brook is a 335-square-kilometre package covering a 26-kilometre strike of Wapske formation with its numerous felsic units. An NI 43-101 technical report has been completed in August, 2024.

E-Power Resources Inc. (CSE: EPR) (‘E-Power’ or the ‘Company’) is pleased to report results from Phase 1 of the 2025 Exploration Program being completed on the Tetepisca Flake Graphite Property located in the North Shore region of Quebec. Highlights of results include:

• Several high grade (> 10% Cg) samples including a high grade sample of 26.4% Cg from a target area on the northern part of the property which was discvered in 2024.

• Several high grade (> 10% Cg) samples including a high grade sample of 68.7% Cg from Graphi-Centre, the Company’s highest priority target on the Tetepisca Property.

• Discovery of a new flake graphite showing which includes a high grade grab sample of 54.7% Cg located on a long conductive linear trend on the southwestern part of the property.

James Cross, President and CEO of E-Power commented: ‘Phase 1 of our 2025 Exploration Program further demonstrates the from-surface, high grade resource potential of several flake graphite targets on the property. Metallurgical testwork, detailed mineralogy, and continued geological evaluation will result in characterization of the potential deposits and prioritization for advanced evaluation and delineation. By characterizing the different resource delineation targets, we expect to be able to attract users of graphite, and companies who want to secure that link in the supply chain; those who need politically-reliable graphite sources. Those users and traders have the capital to turn it quickly into a resource, and ultimately, a secure source of easily accessible graphite.’

During June 2025, the Company completed Phase 1 of its 2025 exploration and development program on the Tetepisca Flake Graphite Property. Field work included geological and geophysical mapping and prospecting during which 44 grab samples were collected. The objectives of the field work were to:

1) Follow up and expand Flake Graphite discoveries made in 2024 located on the lesser explored northern part of the property,

2) Complete detailed geological mapping and sampling on Graphi-Centre, the Company’s highest priority flake graphite target on the Tetepisca Property,

3) Geological mapping and sampling along the Syndicate Target, a long linear airborne conductor which includes 6 historical flake graphite showings and a historical drill hole with an intercept of 12.74% Cg over 9.55 metres.

4) Collect samples of approximately 250 kg each from selected exposures for preliminary metallurgical test work fron the Graphi Centre target and from the northern claims.

Map 1 is an index map illustrating target areas explored and the locations of bulk samples collected during Phase 1 of the 2025 exploration program.

Northern Claims Target Area and Results

As part of the 2024 exploration program, the company completed a program of geological and geophysical prospecting and mapping on the northern part of the property. The work was focussed on evaluating selected conductors and conductor trends derived from interpretation of the Company’s airborne electomagnetic (‘EM’) survey completed in 2022 as well as historical airborne EM surveys. The 2024 prospecting work resulted in the discovery of 5 flake graphite bearing conductors all of which are characterized by numerous samples > 5% Cg and and all containing high grade samples > 20% Cg (Map 2).

During Phase 1 of the 2025 program, follow-up geological and geophysical mapping and prospecting was completed with the objective of expanding the surface exposure of the N3 and N4 targets. On the N3 target, one additional outcrop was located and stripped. Three grab samples of the exposure returned 23.1 % Cg, 23.0 % Cg, and 17.95% Cg (Map 3). The N3 target is exposed, in isolated outcrop exposures, over a distance of approximately 330 m parallel to the airborne conductive trend. Depth of overburden prohited further exposing the conductive trend.

https://images.newsfilecorp.com/files/9160/265515_a6f7e74ad4f2e82f_003full.jpg

Work in the area of the N4 target resulted in a significant expansion of the footprint of graphite bearing stratigraphy coincident with airborne conductive trends. Samples recovered from the north-northeast conductive trend west of the 2024 target area returned values of 26.4% Cg, 21.7% Cg, 17.95% Cg, and 7.44% Cg (Maps 2 and 3). A single sample located approximately 35 metres north of 2024 sampling returned a value of 18.05% Cg.

Flake graphite mineralization discovered on the northern claims in 2024 and 2025 is hosted by strongly deformed, high metamorphic grade, sedimentary rocks. Airborne magnetic and EM conductivity patterns indicate that the graphite bearing stratigraphy is part of a complexly folded and faulted sequence continuous from southwest of the N5 target to north, north of the N1 target, and which includes the Uatnan deposit as well as historical graphite mineralization in surface showings and in diamond driill hole intercepts (Maps 1 and 2).

Graphi-Centre Target Area and Results

The Graphi-Centre target area, located in the southern part of the Tetepisca Flake Graphite property, is a domain of curved magnetic and conductive lineaments interpreted as the hinge zone of complexly folded, variably magnetic and conductive stratigraphy (Map 4). The Graphi-Centre domain hosts the historical Graphi-Centre graphite occurrence and a number of historical graphite bearing to high grade graphite grab samples. During 2021, the Company completed a ground based electromagnetic survey to aid in the mapping and interpretation of airborne conductors, and in 2023 drilled 632.7 metres in 5 NQ diamond drill holes and an additional 7.45 metres of BQ core in 3 man-portable drill holes. Highlights of the drilling include 3.80 metres at a average grade of 17.85% Cg. During Phase 1 2025, the Company initiated a program of detailed geological mapping and sampling on the southern part of the Graphi-Centre target area. Fifteen samples were taken from the southern part of the Graphi-Centre target. Highlights of the mapping and sampling include a high of 64% Cg from a grab sample on the South Limb Zone and a high of 68.7% Cg from a grab sample at the western end of the North Limb Zone (Map 4).

Syndicate Target and Results

The Syndicate Target comprises a southeast trending linear airborne conductor approximately 12 kilometres long located in the southwest part of the property. The conductor hosts 6 historical graphite showings; 3 of which were discovered by the Company in 2019 and one of which is a historical drill hole with an intercept of 12.74 % Cg over an intersection length of 9.55 metres (Map 5). During Phase 1 2025, mapping and prospecting resulted in the discovery of an additional showing along the syndicate trend defined by 5 flake graphite bearing samples colleted over a 28 metre southeast trend length. Cg analyses of the 5 samples range from 5.07% Cg to 54.7% Cg (Map 5).

Summary and Next Steps

The Tetepisca Graphite district contains approximately 126 Mt Mt of Measured and Indicated flake graphite mineralization at an average grade of approximately 14% Cg in 3 deposits, one of which has advanced through feasibility containing a reserve of approximate 4.7 Mt of ore at an average grade of 27.8 % Cg. E-Power is the largest holder of mineral rights in the Tetepisca Graphite District with 234 claims covering 12,840 hectares. The E-Power property contains the stratigraphy and geophysical signatures correlated with that hosting the district resources and contains 9 recorded historical graphite showings. E-Power has added to the inventory of showings with a number of graphite discoveries property-wide including those in the northern claim group discovered in 2024.

Since entrance into the Tetepasca Graphite District in 2019, E-Power has been completing a comprehensive property-wide assessment of flake graphite resource potential. The Company is anticipating the near-term reporting of metallurigical testwork initiated during the winter of 2025 from the Captain Cosmos, Syndicate, and Graphi-West Showings. Next steps include continued field work during Phase 2, 2025 and the initiation of additional metallurgical test work and detailed mineralogy study from selected showings. The Company is advancing towards target prioritization for advanced exploration, evaluation, and resource delineation.

About the Tetepisca Property

The Tetepisca Property is located approximately 220 km north of the town of Baie-Comeau in the North Shore Region of Québec. The property consists of 234 claims covering an area of approximately 12,840 hectares within the emerging Tetepisca Graphite District (‘TGD’). The property is 100% owned by E-Power. Fifty-two claims, located in the southern part of the property, are subject to a 1.5% NSR held by a group of local prospectors; otherwise the Tetepisca property remains unencumbered. The TGD is an active graphite exploration and development district with delineated measured and indicated resources in excess of 120 Mt at an average grade of approximately 14% Cg. The Company’s Tetepisca property is strategically located over continuous bedrock conductive horizons that are known and interpreted to be due to graphite and which hold significant potential to host flake graphite resources. The intersection of graphite in our 2023 drilling and the results of our 2024 exploration program to date confirms the Company’s exploration model and provides the basis for continued exploration and evaluation.

Reports 1.33 Million Tonnes Grading 493 G/T AgEq For 21.1 Million Ounces AgEq Indicated and 5.14 Million Tonnes Grading 525.9 G/T AgEq For 86.88 Million Ounces AgEq Inferred

Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) (‘Blackrock’ or the ‘Company’) is pleased to report the results for its updated mineral resource estimate (the ‘Updated MRE’) for its 100% owned Tonopah West project (‘Tonopah West’ or the ‘Property’), located in West-Central Nevada within Nye and Esmeralda Counties, Nevada, United States. Tonopah West is conveniently situated directly adjacent to the town of Tonopah in Western Nevada, with highway US 95 crossing the Property, and the resource area lies exclusively within patented mining claims and fee lands. All amounts herein are presented in United States Dollars unless otherwise stated.

HIGHLIGHTS:

• The Updated MRE contains a total of 0.107 million ounces (‘Mozs‘) of gold (‘Au‘) and 9.5Mozs of silver (‘Ag‘), or 21.1Mozs of silver equivalent (‘AgEq‘) of indicated mineral resources, and 0.47 Mozs of Au and 35.5Mozs of Ag, or 86.88Mozs of AgEq of inferred mineral resources.

• Indicated mineral resources were not previously included in the mineral resource estimate for Tonopah West effective August 25, 2024 (the ‘Previous MRE‘), highlighting how Blackrock’s recent in-fill drilling program (the ‘M&I Conversion Program‘) at Tonopah West which commenced in mid-July 2024 has confirmed previous inferred mineral resource estimates and improved geologic confidence in the mineral resource estimate on the Project.

• At a 180 grams per tonne (‘g/t‘) AgEq cutoff, the average block-diluted grade of the indicated mineral resources is 493 g/t AgEq and the average block-diluted grade of the inferred mineral resources is 525.9 g/t AgEq.

• The Updated MRE includes 83 new drillholes completed in 2024-2025 and is based on a refined geologic model which was updated to reflect the new drilling and added more detail to the spatial distribution of mineralized veins.

• Silver and gold mineralization at Tonopah West remains open to the northwest, east and internally between the main bodies of mineralization, and at depth.

Table 1: Tonopah West Updated 2025 Mineral Resource Estimate

¹ AgEq cutoff grade is based a total mining, processing and G&A cost of $129/tonne (see Table 2).

2 Silver Equivalent grade ratio used in this news release is 100:1 which is based on silver and gold prices of $27/ounce and $2,700/ounce, respectively, and recoveries for silver and gold of 87% and 95%, respectively. AgEq Factor= (Ag Price / Au Price) x (Ag Rec / Au Rec) or ($27/$2700) x (0.87/0.95) = 0.009158; g AgEq/t = g Ag/t + (g Au/t / AgEq Factor).

³ Rounding as required by reporting guidelines may result in apparent discrepancies between tonnes, grade, and contained metal content.

⁴ Mineral resources are not mineral reserves and do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

⁵ The estimate of mineral resources may be materially affected by geology, environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues, although there are currently no known factors related to these issues which could materially affect these mineral resource estimates.

The Updated MRE was prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum (‘CIM‘) Definition Standards – For Mineral Resources and Mineral Reserves adopted by the CIM May 19, 2014, and in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (‘NI 43-101‘). The Updated MRE was prepared by RESPEC Company LLC (formerly Mine Development Associates)(‘RESPEC‘) with an effective date of August 25, 2025.

Andrew Pollard, the Company’s President and Chief Executive Officer, stated, ‘As evidenced by the Updated MRE, the Company has delivered on its guidance for the M&I Conversion Program, delineating 1.333Mtonnes of indicated mineral resources while maintaining the high-grade (493 g/t AgEq) within the shallowest portion of the Tonopah West deposit. The Updated MRE shows the continuity of high grades within the tighter spaced drill pattern and is showing trends similar to those documented in the historic Victor and Ohio veins located to the east. This upgrade to the DPB South area gives the Company added confidence to pursue the permits required, refine the engineering designs and engage the talent for advancing the project to the next phase which includes an exploration decline, test mining and extracting a bulk sample.’

He continues, ‘The Company’s current exploration programs at Tonopah West are focused on the expansion opportunities to the northwest and east. The results from the recently completed northwestern expansion drilling programming and the currently active eastern expansion drilling program are intended to be incorporated into an updated mineral resource estimate and updated preliminary economic assessment of the Tonopah West deposit planned for Q1-2026.’

The Updated MRE is presented with block diluted grades. The AgEq block model grades are based on $27 per ounce of silver, $2,700 per ounce of gold, and 87% and 95% recoveries for silver and gold, respectively.

The Updated MRE is reported using a cutoff grade which was calculated from estimated underground mining costs and metallurgical recoveries to meet reasonable prospects for eventual economic extraction. Table 2 shows assumed mining, processing, and G&A costs.

Table 2: Tonopah West mining, processing and G&A costs at the listed gold and silver price

The Updated MRE on Tonopah West has been tabulated by four separate spatial areas or zones that make up the Property (Victor, DPB North, DPB South and Northwest). The areas are not materially different geologically but have been separated for logistical purposes in future mining scenarios.

¹ AgEq cutoff grade is based a total mining, processing and G&A cost of $129/tonne (see Table 2).

² Silver Equivalent grade ratio used in this news release is 100:1 which is based on silver and gold prices of $27/ounce and $2,700/ounce, respectively, and recoveries for silver and gold of 87% and 95%, respectively. AgEq Factor= (Ag Price / Au Price) x (Ag Rec / Au Rec) or ($27/$2700) x (0.87/0.95) = 0.009158; g AgEq/t = g Ag/t + (g Au/t / AgEq Factor).

³Rounding as required by reporting guidelines may result in apparent discrepancies between tonnes, grade, and contained metal content.

An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

⁵ The estimate of mineral resources may be materially affected by geology, environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues, although there are currently no known factors related to these issues which could materially affect these mineral resource estimates.

Recent Blackrock drilling which underpins the Updated MRE is summarized in Tables 4 and 5.

Table 4: Summary of Blackrock drilling to date summarized by metre

Table 5: Summary of Blackrock drilling to date summarized by hole count

The Updated MRE includes 83 new drillholes (representing 33,248 metres of total aggregate drilling) completed in 2024-2025 by Blackrock since the Previous MRE. Blackrock drilling represents 96% of the drillholes contributing to the Updated MRE.

Recent drilling by the Company focused its efforts on collecting drillhole exploration data in key areas of the deposit, including high-density drilling in the DPB South area on 30 metre centers and step-out drilling in the Northwest zone to test mineralization continuity.

The Updated MRE is based on drillholes which are oriented between 90 to 50 degree inclinations from the surface, with up to three drillholes at different inclinations completed from the same drill pad. Drillholes are spaced approximately every 30 metres in the DPB South zone and 50 to 100 metres along sections with 50 metre distance between sections in DPB North and Northwest. At Victor, drillholes are spaced between approximately 25 to 50 metres apart along sections with the sections 50 to 100 metres apart.

The Updated MRE encompasses Victor, DPB North, DPB South, and Northwest zones. The Victor area is approximately 700-metres by 350-metres while the DPB North area is 500-metres by 600 metres, DPB South area is 800 metres by 700 metres, the Northwest area is 1300 metres by 100 metres.

RESPEC was supplied with vein shapes on cross-sections and level-plans generated by Blackrock which were subsequently solidified into a three-dimensional geologic model. Mineralized vein thicknesses in the model ranged from 0.1 to 15.8 metres and averaged 3.0 metres. A representative cross-section of deposit geology and vein intercepts is provided in Figure 1. Silver and gold mineral resources were modelled and estimated as follows:

• Evaluate the drill data statistically;

• Create tightly constrained low-, medium- and high-grade mineral-domain wireframe solids for both silver and gold, using the three-dimensional geologic model as a basis for domain interpretation;

• Code a block model to the silver and gold domains using the mineral-domain wireframe solids;

• Analyze the modelled mineralization geostatistically to aid in the establishment of estimation and classification parameters; and

• Interpolate grades into models comprised of 1.0(east-west) x 1.0(north-south) x 1.0(vertical)-metre blocks using the silver and gold mineral domains to explicitly constrain the grade estimations.

Drillhole assay samples were composited within the mineralized domains. High-grade capping was completed on composite data and established using a statistical analysis for silver and gold. Silver was capped at 3,000 g/t, and gold was capped at 30 g/t.

Specific gravity test work was completed for 370 core samples. Results indicate an average density of 2.46 grams/cm³ for low-grade mineralized vein material, 2.53 grams/cm³ for mid- and high-grade mineralized vein material, and values ranging from 2.11-2.47 grams/cm³ for unmineralized wall rock, which varies by geologic formation.

RESPEC utilized Inverse Distance Cubed (ID³) interpolation for the estimation to obtain a localizing effect in the mid- and high-grade domains, and an Inverse Distance Squared (ID²) in the low-grade domains where mineralization is more diffuse. All estimates are based on a block dimension of 1 metre by 1 metre by 1 metre blocks.

The original deposit had been depleted by historical mining in the Victor area. Approximately 200,000 tonnes of material was removed from the Victor mineral resource estimate.

A cutoff grade for the reported resource of 180 g/t AgEq was selected based on assumed mining costs for underground methods along with processing and G&A costs (see Table 2). At a 180 g/t AgEq cutoff, the average grade of the indicated and inferred mineral resources comprising the Updated MRE is 493.4 g/t AgEq and 525.8 g/t AgEq, respectively.

A technical report is being prepared on the Updated MRE in accordance with NI 431-101 and will be available on the Company’s website and on SEDAR+ at www.sedarplus.ca within 45 days of the date of this news release.
