New Pacific Metals Reports Results of its Pre-Feasibility Study of the Silver Sand Project Post-Tax US$740 NPV (5%), 37% IRR, 157 Million Ounces of Silver

VANCOUVER, BC, June 26, 2024 /PRNewswire/ - New Pacific Metals Corp. (TSX: NUAG) (NYSE-A: NEWP) ("New Pacific" or the "Company") is pleased to report the results of its pre-feasibility study ("PFS") for the Silver Sand project (the "Project") in Potosi Department, Bolivia. The PFS is based on the Mineral Resource Estimate (the "MRE") for the Project, which was reported on November 28, 2022 and is reported in accordance with National Instrument 43‐101- Standards of Disclosure for Mineral Projects ("NI 43‐101").

Highlights from the PFS are as follows (all figures in US Dollars):

• Post-tax net present value ("NPV") (5%) of $740 million and internal rate of return ("IRR") of 37% at a base case price of $24.00/oz silver,
  • Post-Tax NPV (5%) of $638 million and IRR of 33% at the PEA¹ comparative price of $22.50/oz silver,
    
    
• 13-year mine life, excluding the 2-year pre-production period, producing approximately 157 million oz ("Moz") of silver,
  
  • Annual silver production exceeds 15 Moz in years one through three, with life of mine ("LOM") average annual silver production exceeding 12 Moz,
    
    
• Initial capital costs of $358 million and a post-tax payback of 1.9 years (from the start of production) at $24.00/oz silver, and
  
  
• Average LOM all-in sustaining cost ("AISC") of $10.69/oz silver.

"We are excited to share the results of the PFS for Silver Sand, a significant milestone for our Company. These strong results confirm that Silver Sand has the potential to become a high-grade, low-cost, pure silver producer, setting it apart as a rare and valuable asset in our industry. The next step along our journey will be reaching an agreement with local communities to secure surface rights for the project area. Furthermore, our team will continue to collaborate with local communities and authorities to ensure that the mineral wealth at Silver Sand benefits all Bolivians and stakeholders," stated Andrew Williams, CEO and President. "We are very pleased with the progress and look forward to the next phases of development."

AMC Mining Consultants (Canada) Ltd. (mineral resource and reserves, mining, infrastructure and financial analysis) was contracted to conduct the PFS in cooperation with Halyard Inc. (metallurgy and processing), and NewFields Canada Mining & Environment ULC (tailings, water and waste management). The taxation calculations were based on the guidance and expertise of Bolivian local experts engaged by the Company.

Capital and Operating Costs

The Project, as outlined in the PFS, is an open-pit mining operation with mining anticipated to be completed by a contract mining company. The open-pit mine is anticipated to provide ore to a mineral processing plant, producing silver doré on site.

Silver Sand has several advantages that we anticipate will benefit capital and operating costs:

• The mine is expected to be operated by a contractor with current operations in Bolivia. This will eliminate procurement of a mining fleet by the Company and sustaining capital for fleet replacement,
  
  
• The mine is expected to be connected to the national electricity grid to provide low-cost power to the processing plant and other on-site infrastructure, and
  
  
• The site can be accessed via government highways and high-quality local roads. The access road is currently being upgraded and widened by the government.

Costs used in the PFS were estimated based on quotes from multiple contractors, and vendors, as well as internal cost databases from the Company's consultants and indications from local firms.

A summary of capital costs is shown in Table 4. The majority of initial capital costs are related to constructing the mineral processing plant, followed by mine pre-production and development costs, and site infrastructure. Mine pre-production and development costs are primarily composed of waste mining and construction of the tailings storage facility ("TSF") embankment. In comparison to the PEA published on January 9, 2023, the $50 million increase in initial capital costs is primarily due to:

• Reallocating 10Mt of waste material, that was mined in the production phase of the PEA, to the pre-production phase, as further engineering revealed the need for additional material for the TSF embankment (approximately $30 million), and
  
  
• A larger silver leach circuit to extend the leach time, based on the results of the PFS metallurgical test work and further engineering (approximately $20 million).

A summary of operating costs is presented in Table 5.

Mining

It is anticipated that the deposit will be mined using a conventional open pit approach. This entails drilling and blasting, with loading by hydraulic excavators and haulage by off-highway rear dump haul trucks. Ore is expected to be hauled to a crusher or to run-of-mine (ROM) stockpiles. Waste is anticipated to be hauled to external and in-pit waste rock dumps. Open-pit mining is anticipated to commence in Year 2, with 28.0 million tonnes of pre-production mining occurring over a two-year pre-production period. Peak open-pit production is expected to be 18.0 Mt of total material mined in Year 8. A total of 52.0 Mt of ore is anticipated to be mined from open pit operations over the life of mine.

Processing & Metallurgy

Three additional metallurgical programs, building on earlier test work, were completed during 2022 and 2023 and focused on cyanidation and tank leaching. They included bottle roll tests, column leach tests and gravity concentration, in addition to further grindability and sample characterization. The selected PFS flowsheet consists of comminution by crushing, followed by semi-autogenous and ball milling, tank leaching with cyanidation over 72 hours, counter current decantation ("CCD") and zinc precipitation (Merrill Crowe). Zinc precipitate from Merrill Crowe will be treated for copper removal, and then smelted to produce silver doré.

Thickened tailings from the CCD circuit are anticipated to be filtered with pressure filters before being conveyed to the nearby TSF. Upon mine closure, it is anticipated that the TSF will be capped with rock and reclaimed topsoil to provide a secure facility.

Process water is expected to be sourced from the water reservoir adjacent to the process plant and from recycled water from the TSF, supplemented by site runoff as required. A site-wide water balance model has been developed to maximize water recycling over the life of mine.

Mineral Resource Estimate

The MRE, which used conceptual open pit mining constraints for reporting purposes, was previously reported in a news release dated November 28, 2022. The Mineral Resource, stated at a 30 g/t silver cut‐off grade, is shown in Table 6.

Table 6: Mineral Resource as of October 31, 2022

Mineral Reserve Estimate
The open pit Mineral Reserves are reported within an optimized pit design. The Mineral Reserves represent the economically mineable part of the Measured and Indicated Mineral Resource and are presented in Table 7 below.

Table 7: Mineral Reserve estimate as of June 19, 2024

Permitting
The Company continues to progress with community engagement efforts with those individuals located within the Project's area of influence. To finalize the Environmental Impact Assessment Study ("EEIA") for submission to Bolivia's Ministry of Environment and Water, as disclosed in the Company's news release dated January 31, 2024, the Company must obtain surface rights for the Project through long-term land lease agreements, finalize a resettlement and compensation plan for impacted community members and implement measures to safeguard cultural and historical heritage. Discussions are ongoing with local communities to reach these agreements.

Progress towards these agreements has been disrupted by a minority group of artisanal and small-scale miners ("ASMs") operating illegally within our mineral rights whose activities do not align with the development objectives of the Project. Through its extensive community engagement efforts, the Company believes that the interests of this minority group of ASMs do not align with those of the broader communities. These communities have formally acknowledged the Company's mining rights and they have indicated that they expect the cessation of these ASM activities.

The Company has taken steps to address the presence of these ASMs, including the commencement of formal legal proceedings in December 2023. These legal proceedings are led by one of the leading law firms in Bolivia. In addition, on May 7, 2024, the Company successfully obtained an execution order (the "Order") from the Mining Jurisdictional Administrative Authority (the "AJAM") for the reinstatement of its mining rights and is working closely with government authorities to enforce the Order. As efforts to resolve the presence of this minority group of ASMs have intensified over the past several months, our site access for certain activities has been temporarily limited, as expected.

The Company remains optimistic about achieving a favorable resolution, bolstered by community and governmental support to uphold our mining rights and drive positive development outcomes for the Project, benefiting local communities, the Plurinational State of Bolivia, and the Company's shareholders over the next two decades, and beyond, pending positive exploration success. Regarding the extent of the impact of the illegal ASM activities on the Project's Mineral Resources, the Company believes the mineralized material extracted is not significant.

Mining Production Contract
The Company continues to engage with the Bolivia state mining corporation, Corporación Minera de Bolivia ("COMIBOL"), to obtain the ratification and approval of the signed Mining Production Contract (the "MPC") at the Project by the Plurinational Legislative Assembly of Bolivia. As noted in the Company's January 31, 2024 news release, the Company acknowledges the significant role of Mining Cooperatives ("CoOps") in the region's economic and political landscape in areas of the Project that do not encroach on our mineral rights.

The Company is committed to ensuring that the proposed Project delivers shared benefits, including access to milling capacity, technology, infrastructure, capital, and underutilized mining areas. Establishing a framework for coexistence with CoOps in non-encroaching areas of Silver Sand is crucial for securing the necessary support for the ratification and approval of the signed MPC. In light of this, over the past several months the Company has extensively engaged with the relevant CoOps, their affiliate groups, and COMIBOL.

CAUTIONARY NOTE REGARDING RESULTS OF PRELIMINARY ECONOMIC ASSESSMENT

The results of the PEA prepared in accordance with NI 43-101 titled "Technical Report – Silver Sand Deposit Preliminary Economic Assessment" dated February 16, 2023 and with an effective date of November 30, 2022 and prepared by certain qualified persons associated with AMC Consultants are preliminary in nature and are intended to provide an initial assessment of the Project's economic potential and development options of the Project. The PEA mine schedule and economic assessment includes numerous assumptions and is based on both indicated and Inferred Mineral Resources. Inferred resources are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the project economic assessments described herein will be achieved or that the PEA results will be realized. The estimate of Mineral Resources may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues. Mineral resources are not Mineral Reserves and do not have demonstrated economic viability. Additional exploration will be required to potentially upgrade the classification of the Inferred Mineral Resources to be considered in future advanced studies. AMC Consultants (mineral resource, mining, infrastructure and financial analysis) was contracted to conduct the PEA in cooperation with Halyard Inc. (metallurgy and processing), and NewFields Canada Mining & Environment ULC (tailings, water and waste management). The qualified persons for the PEA for the purposes of NI 43-101 are Mr. John Morton Shannon, P.Geo, General Manager and Principal Geologist at AMC Consultants, Mr. Wayne Rogers, P.Eng, and Mr. Mo Molavi, P.Eng, both Principal Mining Engineers with AMC Consultants, Mr. Andrew Holloway P.Eng, Process Director with Halyard Inc., and Mr. Leon Botham P.Eng., Principal Engineer with NewFields Canada Mining & Environment ULC, in addition to Ms. Dinara Nussipakynova, P.Geo., Principal Geologist formerly with AMC Consultants, who estimated the Mineral Resources (collectively, the "Technical Report Authors"). All qualified persons for the PEA have reviewed the disclosure of the PEA herein. The PEA is based on the MRE, which was reported on November 28, 2022. The effective date of the MRE is October 31, 2022. The cut-off applied for reporting the pit-constrained Mineral Resources is 30 g/t silver. Assumptions made to derive a cut-off grade included mining costs, processing costs and recoveries and were obtained from comparable industry situations. The model is depleted for historical mining activities. Mineral resources are constrained by optimized pit shells at a silver price of US$22.50 per ounce, silver metallurgical recovery of 91%, silver payability of 99%, open pit mining cost of US$2.6/t, processing cost of US$16/t, G&A cost of US$2/t, and slope angle of 44-47 degrees. Key assumptions used for pit optimization for the PEA mining pit include silver price of US$22.50 per ounce, silver metallurgical recovery of 91%, silver payability of 99%, open pit mining cost of US$2.6/t, incremental mining cost of US$0.04/t (per 10 m bench), processing cost of US$16/t, tailing storage facility operating cost of US$0.7/t, G&A cost of US$2/t, royalty of 6.00%, mining recovery of 92%, dilution of 8%, and cut‐off grade of 30 g/t silver.
