New Pacific Metals Corp. (TSX: NUAG) (NYSE American: NEWP) together with its local Bolivian partner, reports assay results of the first 21 drill holes from its 2023 Q1 drill program at its Carangas Silver-Gold Project, Oruro Department, Bolivia. Detailed results and drill hole specifications are listed in Tables 1 and 2, and Figure 1.
The 2023 Q1 drilling was a continuation of the 2022 drilling campaign at the Carangas Project. It was originally budgeted as 15,000 meters of diamond core drilling, infilling areas drilled in 2021-2022 and stepping out beyond these previously drilled areas. This drilling program started on schedule in January 2023 and was expanded based on encouraging results and is now complete. A total of 17,623 meters in 39 holes was drilled up to the end of April 2023. Each of the 39 holes intersected mineralization. To date, assay results of the first 21 holes have been received with the remaining holes pending.
HIGHLIGHTS OF DRILL RESULTS
DCAr0171 intersected a wide interval of silver mineralization measuring 205.6 m (76.8 m to 282.4 m) grading 123 g/t Ag, 0.44% Pb and 0.84% Zn, including 77.6 m (126.1 m to 203.7 m) grading 242 g/t Ag, 0.71% Pb and 1.30% Zn. This step-out hole was drilled through fluvial sediment cover to the southwest of the South Dome and implies that shallow silver mineralization remains open to the southwest, beyond the previously drilled West Dome-Central Valley-East Dome corridor.
DCAr0170 was drilled at the western limit of the Central Valley near the West Dome and intersected a wide interval of silver mineralization measuring 292.8 m starting near surface (9.2 m to 302 m) grading 58 g/t Ag, 0.39% Pb and 0.84% Zn, including 80.39 m (9.2 m to 89.59 m) grading 173 g/t Ag, 0.77% Pb and 1.08% Zn.
DCAr0154 intersected an interval of silver mineralization measuring 93.7 m (69.5 m to 163.2 m) grading 50 g/t Ag, 0.20% Pb and 0.53% Zn, including 13.05 m (72.4 m to 84.45 m) grading 280 g/t Ag, 0.36% Pb and 0.83% Zn. To depth, multiple intervals of gold mineralization were intersected, represented by 233.66 m (500.24 m to 733.9 m) grading 0.65 g/t Au and 107.1 m (774.24 m to 881.34 m) grading 0.84 g/t Au. This hole was drilled to test the eastern extension of gold mineralization at depth and the gold intervals in this hole indicate that gold mineralization remains open to the east.
DCAr0151 intersected an interval of silver mineralization measuring 66.76 m starting near surface (6.14 m to 72.9 m) grading 55 g/t Ag and 0.31% Pb, and a second silver interval of 3.63 m (266.13 m to 269.76 m) grading 215 g/t Ag, 0.45% Pb and 0.54% Zn. This hole was drilled in the upper portion of the East Dome.
INAUGURAL MINERAL RESOURCE ESTIMATE
The Company engaged consulting firm RPMGlobal Canada Limited for technical services regarding a National Instrument 43-101 – Standards of Disclosure for Mineral Projects mineral resource estimate report for the Carangas Project. The qualified person (as defined in NI 43-101) from RPMGlobal Canada Limited completed his site visit at the end of March 2023. The resource estimation will commence once assay results of all drill holes are available and the completed resource estimate is expected in the third quarter of 2023.
INTERIM GEOLOGICAL MAPPING PROGRAM
The project technical team is currently conducting detailed surface geological mapping and sampling to refine drill targets over the induced polarization chargeability anomalies beyond the previously drilled areas (Figure 2). This mapping program is planned for the interim period before the expected resumption of drilling activities in the second half of 2023. These IP chargeability anomalies demonstrate a geophysical signature similar to the one observed in the drilled-off area of the Central Valley which hosts the bulk silver-gold mineralization discovered at the Carangas Project.

Notes: | ||||||||||
1. | Drill location, altitude, azimuth, and dip of drill holes are provided in Table 2 | |||||||||
2. | Drill intercept is core length, and grade is length weighted. True width of mineralization is unknown due to early stage of exploration without adequate drill data. | |||||||||
3. | Calculation of silver equivalent (“AgEq”) is based on the long-term median of the August 2021 Street Consensus Commodity Price Forecasts, which are US$22.50/oz for Ag, US$0.95/lb for Pb, US$1.10/lb for Zn, US$3.40/lb for Cu, and US$1,600/oz for Au. The formula used for the AgEq calculation is as follows: AgEq = Ag g/t + Pb g/t * 0.0029 + Zn g/t * 0.00335 + Cu g/t * 0.01036 + Au g/t * 71.1111. This calculation assumes 100% recovery. | |||||||||
4. | A cut-off of 20 g/t AgEq is applied to calculate the length-weighted intercept. At times, samples lower than 20 g/t AgEq may be included in the calculation of consolidation of mineralized intercepts. |

QUALITY ASSURANCE AND QUALITY CONTROL
The Company maintains tight sample security and quality assurance and quality control for all aspects of its exploration program at the Carangas Project. Drill core is logged, photographed and split on-site by the company and stored under secure conditions until being shipped in security-sealed bags by New Pacific staff in Company vehicles, directly from the project to ALS Global in Oruro, Bolivia for preparation, and ALS Global in Lima, Peru for geochemical analysis. ALS Global is an ISO 17025 accredited laboratory independent from New Pacific. All samples are first analyzed by a multi-element ICP package (ALS code ME-MS41) with ore grade specified limits for silver, lead, and zinc, further analyzed using ALS code OG46. Further silver samples over specified limits are analyzed by gravimetric analysis (ALS code of GRA21). Gold is assayed first by ICP and then by fire assay with AAS finish (ALS code of Au-AA25). Certified reference materials, various types of blank samples and duplicate samples are inserted into normal drill core sample sequences prior to delivery to the laboratory for preparation and analysis. The overall ratio of quality control samples in sample sequences is around twenty percent.

ABOUT NEW PACIFIC
New Pacific is a Canadian exploration and development company with precious metal projects in Bolivia. The Company’s flagship project, the Silver Sand Silver Project, has released its inaugural preliminary economic assessment (the “PEA”) results in January 2023. The PEA study shows a post-tax NPV (5% discount) of US$726 million with an IRR of 39%, underpinned by a total silver production of 171 million ounces over 14 years of mine life. At the recently discovered Carangas Silver-Gold Project, a resource drilling program of more than 50,000 meters was completed in 2021-2022. The third project, the Silverstrike Silver-Gold Project, had a 6,000 meter discovery drill program in June 2022.
