VANCOUVER, BC, April 29, 2024 /PRNewswire/ - New Pacific Metals Corp. (TSX: NUAG) (NYSE American: NEWP) ("New Pacific" or the "Company") is pleased to announce the positive results of its metallurgical test program for its Silver Sand project ("Silver Sand") located in Potosi Department, Bolivia. The test program was conducted to meet the standards required for the Company's upcoming Preliminary Feasibility Study (the "PFS"). Highlights from the test program include:
Andrew Williams, President and CEO, states: "Our PFS metallurgical test program has demonstrated the exceptional metallurgical properties of Silver Sand. Recoveries remained consistent with those assumed in the PEA, but with reduced cyanide consumption highlighting the potential for reduced operating costs in our upcoming PFS.
We remain on track to deliver the results of the PFS in June. This test program is an important derisking step for Silver Sand. We will also evaluate a gravity concentration and regrind circuit before finalizing the PFS, which may further enhance project economics."

Additional technical details
The metallurgical test program covered a broad range of characteristics including mineralogy, comminution, gravity concentration, cyanide leaching (utilizing both bottle roll and lifter bottle roll methods), and silver precipitation through zinc dust (employing the Merrill-Crowe process). Tailings testing encompassed evaluations of slurry characteristics (such as thickening, filtration, and rheology), environmental factors, and the transportable moisture limit.
Two life-of-mine and fourteen variability composite samples were used in the test program. Bureau Veritas's Metallurgical Division in Richmond (British Columbia, Canada), ALS Metallurgy in Kamloops (British Columbia, Canada), ALS Metallurgy in Perth (West Australia, Australia), SGS in Burnaby (British Columbia, Canada) and Pocock Industrial in Salt Lake City (Utah, USA) completed the work.
Complete details and analysis of the metallurgical test program will be incorporated into the upcoming PFS. Below is a summary of additional technical details from the test program:

ABOUT NEW PACIFIC
New Pacific is a Canadian exploration and development company with three precious metal projects in Bolivia. The Company's flagship Silver Sand project has the potential to be developed into one of the world's largest silver mines. The Company is also rapidly advancing its Carangas project towards a Preliminary Economic Assessment. For the Silverstrike project, broad oxidized gold mineralization was intercepted near surface from the company's discovery drill program in 2022.

CAUTIONARY NOTE REGARDING RESULTS OF PRELIMINARY ECONOMIC ASSESSMENT
The results of the independent preliminary economic assessment contained in the PEA are preliminary in nature and are intended to provide an initial assessment of the Silver Sand Project's economic potential and development options. 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 Mining Consultants (Canada) Ltd. ("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 (as defined in NI 43-101) for the PEA for the purposes of NI 43-101 are Mr. John Morton Shannon, P.Geo, General Manage 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 with AMC Consultants, who estimated the mineral resources. 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.
