CEO.CA Chairman's Briefing

VANCOUVER, BC / ACCESSWIRE / November 30, 2023 / Highlander Silver Corp. (CSE:HSLV) (the "Company" or "Highlander Silver") is pleased to announce that it has entered into a share purchase agreement dated November 29, 2023 (the "Share Purchase Agreement") with SSR Mining Inc. ("SSR Mining") to acquire the San Luis gold-silver project (the "San Luis Project") located in Ancash Department of central Peru (the "Transaction").

Highlights

• Transformational acquisition for Highlander Silver of the San Luis Project
• Historical Measured & Indicated mineral resources of 348,000 ounces (oz) of gold (Au) grading 22.4 g/t Au, and 9,003,300 oz silver (Ag) grading 578.1 g/t Ag
• Multiple targets for growth on the property given limited and focused historical drilling, open extensions to resources, and undrilled targets supported by highly anomalous (> 4 g/t Au) trenching and rock samples
• Extensive ground holding totalling 23,098 Ha has yet to be systematically explored with many structures that have not yet been sampled providing further exploration potential
• Highlander Silver to implement a comprehensive program of geological mapping and sampling to develop a technical assessment of the discovery potential before more focused exploration on the highest priority targets
• Ancash Department is well-known for mining in Peru with major past and present production from the Pierina gold mine and Antamina copper-zinc mine, respectively
• Financing for this transformative acquisition is backstopped by the Augusta Group and members of the Lundin family

(See "San Luis Historical Mineral Resource" below for further details.)

A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource and the Company is not treating the historical estimate as a current mineral resource.

David Fincham, President and CEO commented: "We are delighted to be bringing the high-grade San Luis gold-silver project into our portfolio, and are very impressed by the size and grade of the historical resource contained within the Ayelen and Ines vein structures. We believe this deposit may be one of the highest-grade gold-silver deposits of its size that is yet to be mined in the world. Additionally, there may be exceptional growth and discovery potential on this large, but only partially prospected and explored property. There are numerous compelling exploration targets based on previous field mapping and rock chip sampling, and we believe that the district has potential to yield much more. This acquisition has the potential to be transformative for Highlander Silver and aligned with our vision of building a portfolio focused on world-class silver gold projects to the benefit of all our stakeholders."

Historical Mineral Resource

The San Luis Project has a historical measured and indicated mineral resource estimate of 348,000 ounces (oz) of Au grading 22.4 g/t Au, and 9,003,300 oz Ag grading 578.1 g/t Ag. Test work developed on the historical mineral resource projected gold and silver recoveries of greater than or equal to 90% using conventional cyanide leach processing methods. The Company plans to undertake work to verify and update the historical estimate as a priority. See "San Luis Historical Mineral Resource" below for further details.

Exploration upside potential

The San Luis Project is district-scale, with the mining concessions covering 23,098 hectares, or approximately 230 km². The fertility of the district has been demonstrated by both evidence of multiple deposit styles and by the high number of targets generated to date from limited exploration. Following discovery of the Ayelen - Ines vein systems where the historical resource is located, the main focus was on resource development, meaning that systematic exploration has yet to be completed across much of the property. Targets on the property include low to intermediate sulfidation epithermal gold-silver veins, copper - molybdenum porphyries, silver, lead, zinc ± copper hydrothermal breccias and silver, lead, zinc ± copper replacement mantos.

The Bonita target, a 600 m long array of complex quartz veins/veinlets has had limited drilling, with just two historic drill holes including BOD-001 which returned 35.25 m of 5.54 g/t Au and 25.43 g/t Ag, from 19.1 m downhole. To date, seven additional mapped and sampled gold-silver vein targets have been defined including Carhuan-Puquio and Gemelas-Cenicienta, within 2 km of the historic resource area, reporting multigram gold rock chip samples. Further targets for follow up occur more broadly across the property represented by the 1 to > 4 g/t gold samples on the map below. Finally, two copper - molybdenum porphyry targets also require further work to assess their potential.

Information relating to the larger property exploration work including geological mapping, surface sampling, and the two holes drilled at the La Bonita target reflect work performed by SSR Mining on the property to-date. In a recent visit to the property by Highlander Silver staff, drill core from both Aylene and the Bonita vein systems were inspected observing significant low-sulphidation style vein intercepts. Notwithstanding, a qualified person has not done sufficient work to fully verify the information at this stage, nor has a qualified person been provided with information that would be required to verify sample data, analytical techniques or quality assurance and control measures that may have been in place during the execution of the exploration work.

The Company plans to engage in geologic mapping and sampling as a first step to verify the historical information and to understand the exploration potential of the district. This work will enable prioritization of targets prior to permitting and drilling.

Community engagement

Community access agreements have been established by previous operators. As a new operator, the Company recognizes the opportunity to establish fresh long-term mutually beneficial relationships with the local communities and will strive to do this from the outset.

San Luis Project Acquisition

Pursuant to the Share Purchase Agreement the Company has agreed to purchase the San Luis Project from SSR Mining through the purchase of SSR Mining's direct and indirect shareholdings of four subsidiary companies, in consideration for an initial payment of US$5,000,000 in cash or US$7,500,000 in common shares of the Company, or a combination thereof, (the "Initial Consideration"). If any portion of the Initial Consideration is paid in common shares of the Company, such number of common shares will not exceed 4.9% of the Company's issued and outstanding common shares as at the closing date.

The Company may pay up to an additional US$37,500,000 in cash to SSR Mining as contingent consideration (the "Contingent Consideration") upon completion of certain milestones in relation to the San Luis Project. The Contingent Consideration is only accrued and payable if and when the following milestones are achieved:

a) $2,500,000, after the commencement of an initial drilling program at the San Luis Project;

b) $5,000,000 after the completion of a feasibility study on any portion of the San Luis Project;

c) $10,000,000 after the beginning of commercial production;

d) $10,000,000 after the first anniversary of commercial production; and

e) $10,000,000 after the second anniversary of commercial production.

Pursuant to the Share Purchase Agreement, a 4% net smelter returns royalty (the "Royalty") on the San Luis Project is to be granted to SSR Mining prior to closing of the Transaction. At any time before the commencement of mine construction on the San Luis Project, the Company may buy back half of the Royalty for US$15,000,000, which if, exercised, would reduce SSR Mining's royalty interest to 2%.

Closing of the Transaction is subject to certain conditions, including receipt of all required regulatory approvals. Closing is currently expected to occur in Q1 2024.

San Luis Historical Mineral Resource

The historical mineral resource is included in a Technical Report titled "Technical Report for the San Luis Feasibility Study, Ancash Department, Peru" (the "Technical Report"), with an effective date of June 4, 2010. The report was prepared as a National Instrument 43-101 101 - Standard of Disclosure for Mineral Projects ("National Instrument 43-101") technical report for Reliant Ventures S.A.C. and Silver Standard Resources Inc. by Mine and Quarry Engineering Services, Inc., RR Engineering, Milne & Associates, Resource Modeling Inc, Resource Evaluation Inc., and Montgomery Watson Harzag Americas Inc, and can be accessed on SSR Mining's SEDAR+ profile. The historical estimate is considered to be relevant and reliable for the purposes of the Company proceeding with the Transaction as it provides an indication of the potential significance of the San Luis Project.

The Technical Report provides details on mineral resources and reserves, as well a potential development option for the San Luis Project that considers underground mining and processing using conventional cyanide leach methods. However, the prices, costs, and development strategy and options are no longer current and need to be re-evaluated using assumptions and qualifications that are more reflective of today's environment.

Below is a summary of the historical resource estimate from the Technical Report.

The San Luis system is a volcanic hosted, low sulphidation, epithermal quartz, precious metals deposit. Gold occurs as electrum and silver is present as acanthite, electrum, and other silver sulphosalts.

The Ayelen vein is the better of the known vein structures with more than 85% of the historical mineral resource derived from this single structure. Trenching and diamond drilling have traced this structure along a NNW strike for over 700 meters, with a steep (80º) down dip extension of more than 300 meters. True thicknesses of individual vein segments vary from tens of centimeters to more than 10m, with an average width of 1.5m to 3.0m.

Mineral resource models were developed based on samples obtained from 96 surface trenches (947m) and 136 drill holes (22,354m). Capping was used to reduce the influence of erratic high-grade values. Block grades were estimated using one-meter composites and inverse distance weighting. Estimated blocks were classified as either Measured, Indicated or Inferred mineral resources based on distance to samples. For the Ayelen vein, blocks within 15 meters of surface trenches were classified as Measured. Ayelen vein blocks within 25m of sample data were classified as Indicated. The remaining estimated Ayelen blocks were classified as Inferred. An average dry density value of 2.61g/cm³ determined from 193 bulk density measurements was used for the resource calculation. The resulting historical mineral resource is shown in the table below.

Historical Mineral Resource Summary

Notes:

• The historical mineral resources are reported using a 6.0g/t Au equivalent cutoff grade. The gold equivalent calculation assumed a gold to silver price ratio of 65:1, and metal recoveries were not considered.
• The historical measured, indicated and inferred mineral resources use categories as defined by the Canadian Institute of Mining, Metallurgy and Petroleum CIM Definition Standards on Mineral Resources and Mineral Reserves

A qualified person has not done sufficient work to classify the historical estimate as a current mineral resource and the Company is not treating the historical estimate as a current mineral resource. Additional work including some re-sampling of historical core and a review of the geological model, will be necessary to verify the historical resource estimate.
