Near Surface Silver Mineralization Intercepted in 190 out of total 195 holes;
Numerous Significant Intercepts include 99.91 metres grading 244 g/t Ag
VANCOUVER, British Columbia – February 20, 2019 -- New Pacific Metals Corp. (TSX-V:NUAG) (OTCQX:NUPMF) (“New Pacific” or the “Company”) is pleased to announce the second batch of drill results from its wholly-owned Silver Sand Project in Potosí Department, Bolivia.
As announced previously on the Company’s news release dated January 22, 2019, the drilling program commenced in mid-October 2017. A total of 55,010 metres in 195 HQ size diamond core drill holes had been completed by mid-December 2018. The drill program covers an area of approximately 1,600 m long in the north-south direction and up to 800 m wide in the east-west direction. The holes were drilled along northeast 60 degree oriented sections with a 50 m spacing between the sections. Most drill holes are drilled at a dip angle of 45 degrees to penetrate the principal trend of the mineralized structure zones with an average hole length of approximately 285 m. The results for the first batch of 98 drill holes were released on January 22, 2019. This news release discloses the assay results of the remaining 97 holes, of which 96 holes intercepted silver mineralization. These 97 holes were drilled mainly to the north of the section 60 covering an area of approximately 1,100 m long north-south and 800 m wide in the east-west direction.

(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. Please refer to Table-1 – Composited Drill Intersections of Mineralization below for details.)
Based on the drilling results, the drill holes usually penetrate first through a few metres up to more than 70 m thick layer of reddish siltstone and mudstone units of Cretaceous Tarapaya Formation, then into massive altered white colour arenites or sandstones units of the Cretaceous La Puerta Formation where silver mineralization is hosted. At the contact of these two units, massive or densely disseminated pyrite mineralization of a few metres wide in thickness typically occurs. Tin mineralization in the district is often associated with massive pyrite, locally called “Bolivia manto type of tin mineralization”. At depth, many drill holes end at the unaltered reddish sandstone units of the Cretaceous La Puerta Formation. The Cretaceous Formations sit unconformably on a basement of tightly folded and faulted Paleozoic marine clastic sediments.
The mineralized sandstone and siltstone units of the Cretaceous Formations are shallow dipping or sub-horizontal and gently folded into open synclines and anticlines with their hinges shallowly plunging to North-North-West (“NNW”) direction. To the north of Silver Sand Project, numerous porphyrytic dacitic sills and dykes of Miocene age intrude and cut the Cretaceous sediments which are believed to be closely associated with silver mineralization in the district.
Silver mineralization is observed to be associated with fractures as sheeted veins, stockwork veinlets, crackle veins and breccia zones of sulfosalts and sulfides containing silver (Figure-1) in altered sandstones units which were bleached white due to sericite alteration of original reddish sandstones resulting in a sub-horizontal mineralized zone of up to more than 200 m in thickness beneath the Tarapaya red siltstone and mudstone (Figure-2). The most common silver-containing sulfosalt is freibergite associated with small amounts of miargyrite, polybasite, bournonite, boulangerite, andorite and bismuthinite.
The mineralized fractures generally extend NNW sub-vertically and slightly dipping west. The mineralized bodies within the Silver Sand Project were detected by drilling within an area of up to 1,600 m long in north-south direction and 800 m wide in east-west direction within the property limit and remain open to both the north and the west. Mineralized bodies were oxidized to various extents to depth and could extend from near surface to a depth of up to more than 250 m.
2019 Drilling Program
Assay results of surface sampling of hundreds of artisanal mining dumps and continuous chip-sampling from artisanal underground mining tunnels reveal the silver mineralized fracture zones could extend at least by 3,000 m to the north and 500 m to the west and the east, as well as extending up to 1,000 m to the south of the areas drilled in 2018. These newly identified extensions of the mineralized fracture zones will be the targets of the continuing drilling program in 2019 once the rainy season ends by the end of March.
In addition, the Company is currently applying for permits to drill the areas covered under the Mining Production Contract (“MPC”) executed with COMIBOL in January 2019. The drilling program for the MPC areas will commence once the drilling permits are granted by local authorities in two to three months.
Quality Assurance and Quality Control
HQ size drill core samples from altered and mineralized intervals were split into halves by diamond saw cutting with an average sample interval of one to one and half metres long at the Company’s core processing facility located in Betanzos, a local town 20 km away from the project site. Half core samples are stored in secured core storages for future reference and the other half core samples are shipped in security sealed bags to ALS Global in Oruro, Bolivia for preparation, and ALS Global in Lima, Peru for geochemical analysis with the code of OG46 for elements of silver, lead and zinc. Silver overlimits further go to gravimetric analysis with the code of GRA21.
A standard quality assurance and quality control (“QAQC”) protocol is employed to monitor the quality of sample preparation and analysis. Standards of certified reference materials, blanks and duplicates are 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, one blank sample, and one duplicate sample). The assay results of QAQC samples did not show any significant bias of analysis or contamination during sample preparation.
