New Pacific Metals Corp. (TSX-V: NUAG) (OTCQX: NUPMF) is pleased to announce the assay results of the second batch of 32 drill holes from its wholly-owned Silver Sand Project located in the Department of Potosí, Bolivia. The assay results continue to show wide intervals of silver mineralization. Currently there are three rigs operating on site with a fourth rig to arrive in August to expedite drilling at Silver Sand. Of the 32 drill holes, 19 holes were drilled to infill the drill grid to a density of 25 metres by 25 metres to confirm continuity of mineralization in selected areas drilled in 2018, and 13 holes were drilled step-out to the north testing extension of known mineralized zones. Holes were approximately oriented at azimuths of 60 degrees with dips of -45 degrees normal to the strike and dip of mineralized structures.
All the infill drill holes intercepted significant silver mineralization in mineralized fracture zones similar to those seen in the assay results for those holes completed in 2018 drill campaign and ongoing 2019 drill campaign; the first drill results of which were released on June 6, 2019. Holes drilled to the south of section 60 have encountered mined out intervals within zones of wide silver mineralization where higher grade silver may have been selectively mined out in the past. The step-out drill holes to the north of section 44 on the eastern side of the mineral deposit also intercepted significant silver mineralization evidenced by the wide intercepts in holes DSS4006 grading 174 g/t silver over 42.4 m and DSS422501 grading 183 g/t silver over 104.5 m, indicating that mineralization is open to the north.
Highlights of significant drill intersections are summarized as follows (for a detailed list, please refer to Table-1 – Composited Drill Intersections of Mineralization below):
(True width of the mineralization is unknown, but based on the current understanding of the relationship between drill hole direction and the mineralized structures it is estimated that true width will approximate 80% of the down hole interval length. Please refer to Table-1 – Composited Drill Intersections of Mineralization below for details.)
With the continued exploration success, the Company has engaged AMC Mining Consultants (Canada) Ltd. to undertake an initial resource estimate for the Silver Sand Project.
Quality Assurance and Quality Control
HQ-size drill core samples from altered and mineralized intervals were split into halves by diamond saw, with an average sample length of between one to one and half metres at the Company’s core processing facility located in Betanzos, a small town located 20 kilometres from the project site. Half core samples are stored in a secure core storage facility in Betanzos for future reference, and the other half core samples are shipped in securely sealed bags to ALS Global in Oruro, Bolivia for preparation, and ALS Global in Lima, Peru for geochemical analysis. All samples are first analyzed by a multi-element ICP package (ALS code ME-MS41) with ore grade over limits for silver, lead and zinc further analyzed using ALS code OG46. Further silver over limits are analyzed by gravimetric analysis (ALS code of GRA21).
A standard quality assurance and quality control protocol was employed to monitor the quality of sample preparation and analysis. Standards of certified reference materials and blanks were inserted in normal core sample sequences prior to shipment to lab at a ratio of 20:1 (i.e., every 20 samples contain at least one standard sample and one blank sample). Duplicate samples of coarse rejects at a ratio of 20:1 will be sent to a second internationally accredited lab for check analysis. The assay results of QAQC samples of standards and blanks did not show any significant bias of analysis or contamination during sample preparation.

Notes: g/t = grams per metric tonne.
The table above is intended to show highlights of the drilling program only. The intercepts shown are a weighted average of the sample lengths and grades of all of the samples within that intercept and may include some samples with grades less than 30 g/t silver.
Intersections may contain samples less than 30 g/t silver between higher grade subintervals.
Intervals are drill core length in meters. True width of mineralization zones is estimated at about 80% of drill intervals based on current understanding of the relationship between drill direction and the mineralized structures.
