New Pacific Metals Corp. (TSX: NUAG) (NYSE: NEWP), together with its local Bolivian partner, announce the assay results of the first five drill holes of the 2022 drill program at the Carangas Silver-Gold Project, Oruro Department, Bolivia. Results are summarized in Table 1 and the drill specifications are provided in Table 2 (see also Figure 1).
So far, 16,754 meters in 31 drill holes have been completed at Carangas in 2022, of which the assay results of the first five holes are released herein. Assay results for the remaining 26 holes are pending with estimated turnaround time of up to 10 weeks after sample delivery. The assay results continue to show near surface silver horizons stacking over a broad bulk gold mineralization below.
Currently there are five drill rigs deployed at the Project, of which the three larger drill rigs with capability of 1,000 m capacity depth are focusing on both near surface silver and at deeper gold zones, while the other two smaller drill rigs are focusing on near surface silver zone only.
Highlights
Detailed Description
Hole DCAr0039 intersected a silver horizon of 152.73 m (from 9.35 m to 162.08 m) grading 55 g/t Ag, 0.53% Pb and 1.07% Zn, including 36.75 m grading 195 g/t Ag, 1.19% Pb and 2.57% Zn. Immediately below the silver horizon, the hole intercepted 535.63 m interval (from 162.08 m to 697.71 m) grading 1.00 g/t Au and 11 g/t Ag, including a high-grade interval of 72.16 m grading 3.54 g/t Au and 12 g/t Ag from 450.34 m.
Gold mineralization is hosted in strongly argillic-sericitized ignimbrites and volcanic tuff of dacitic composition with disseminated sulfides and cut by veinlets of pyrite and chalcopyrite, similar to the holes reported previously.
The hole was drilled off the drill grid and across the Central Valley from East Dome to West Dome, in an azimuth direction of 254 degrees and at a high dip angle of -66 degrees.
Hole DCAr0036 intersected two silver horizons, the first with 57.83 m (from 13.17 m to 71 m depth) interval grading 166 g/t Ag, 0.47% Pb and 0.25% Zn, the second interval is 95.55 m (from 114 m to 209.65 m depth) grading 35 g/t Ag, 0.32% Pb and 1.06% Zn. Below the silver horizons, the hole intercepted a gold interval of 215.81 m (from 280.74 m to 496.55 m) grading 0.73 g/t Au and18 g/t Ag. This hole was drilled off grid in the Central Valley in azimuth direction of 230 degrees and at a shallow dip angle of -45 degrees.
Hole DCAr0038 intersected a silver interval of 58.10 m (from 10.0 m to 59.1 m) grading 507 g/t Ag, 0.60% Pb and 0.94% Zn, including a bonanza interval of 5.17 m (from 43.57 m to 48.74 m) grading 6,236 g/t Ag, 2.62% Pb, 6.23% Zn and 0.42% copper. A second silver horizon with an interval of 90.90 m grading 28 g/t Ag, 0.47% Pb and 1.25% Zn was intersected from depth 99.25 m. At further depth, a gold interval of 68.03 m grading 0.41 g/t Au, 3 g/t Ag, 0.31% Pb and 0.52% Zn was intersected from depth 334.27 m. This hole was drilled on a grid close to East Dome in an azimuth direction of 20 degrees and at a shallow dip angle of -45 degrees.
Hole DCAr0037 intercepted an interval of 98.65 m grading 88 g/t Ag, 0.70% Pb and 0.80% Zn from depth 10.85 m to 109.5 m. This hole was drilled off grid across the Central Valley in an azimuth direction of 350 degrees and at a shallow dip of -45 degrees.
Hole DCAr0040 was drilled off grid at East Dome in an azimuth direction of 50 degrees and at a shallow dip angle of -45 degrees and intersected a silver mineralization interval of 38.03 m grading 18 g/t Ag, 0.22% Pb and 0.42% Zn from depth 26.42 m and another silver zone of 157.72 m grading 24 g/t Ag, 0.26% Pb and 0.80% Zn from depth 87.55 m, including a high-grade interval of 34.32 m grading 61 g/t Ag, 0.59% Pb and 1.73% Zn from depth 92.25 m.

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. Due to the early stage of the Project, the Company has not yet completed metallurgical test work on the mineralization encountered to date. | |||||||||
4. | A cut-off of 20 g/t AgEq is applied for calculation of length-weighted intercept. At times, samples lower than 20 g/t AgEq may be included in the calculation of consolidation of mineralized intercepts. | |||||||||
5. | n/a stands for no fire assay of gold was carried out. |

QUALITY ASSURANCE AND QUALITY CONTROL
All samples in respect of the exploration program at the Carangas Project, conducted by the Company and discussed in this news release, are shipped in securely-sealed bags by New Pacific staff in the Company’s vehicles, directly from the field 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 over 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 firstly by ICP method 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 to normal drill core sample sequences prior to delivery to laboratory for preparation and analysis. The overall ratio of quality control samples in sample sequences is around twenty percent.
