York Harbour Metals Announces Remaining Phase 3 Assay Results Extending Mineralization Open at Depth and Along Strike

Vancouver, British Columbia – October 4th, 2022 – York Harbour Metals Inc. (the “Company”) (TSXV: YORK) (OTCPK: YORKF) (Frankfurt: 5DE0) is pleased to report the remaining assay results from its Phase 3 drilling program that was carried out from mid-January to mid-April, 2022. 

The assay results show that the drill-indicated mineralization extends both along strike, thereby joining several of the previously isolated volcanogenic massive sulphide (“VMS”) lenses of the Main Mine Area, and that these lenses have depth extent and could extend farther.

Note:  The above intervals are drilling lengths, not true widths, as the true orientation of the mineralization has not yet been established. YH57-68 was previously reported (September 8th).

Chairman Bruce Durham commented; “The drill results from the Phase 3 drill program indicate there remains significant potential for the Company to discover additional extensions to the copper-zinc mineralization first mined at York Harbour more than 100 years ago. Drill holes such as hole YH-22-61 intersecting 14.77m of high-grade copper-zinc mineralization grading 2.86% copper and 6.95% zinc show areas proximal to the main mine area with thick accumulations of massive copper-zinc sulphides that had not previously been drilled by previous operators. A number of other holes reported today intersected narrower intervals of similar sulphides that expand the known limits of the mineralization.”

QA/QC Procedures

Phase 3 diamond drill core samples were sawn in half lengthwise from core lengths usually varying from 0.3 to 1.50 m, depending upon geological and mineralogical constraints.  Blank, duplicate and standard samples were inserted into the sample string at a rate of one each for every twenty samples.  A total of 128 quality control (‘QC’) samples were inserted into the assay string of 1,289 drill core samples.  These 1,317 samples of massive, semi-massive and stringer mineralization, including QC samples insertions, were initially delivered Activation Laboratories in Ancaster, Ontario and later to AGAT Laboratories in Mississauga, Ontario, both ISO/IEC-accredited laboratories. There the drill core samples were crushed to a nominal minus 2 mm, split into representative sub-samples and then pulverized to at least 95% minus 105 microns before collecting sub-sample pulps for each of the core samples.

All sub-sample pulps were initially analyzed for 38 elements using ICP QC procedures which included fusing with Na2O2.  The fused samples were then dissolved in purified water and acidified with concentrated nitric and hydrochloric acids. The solutions were then measured by an ICP.  Samples are analyzed with a minimum of 10 certified reference materials.

Based upon the initial ICP results, any element returning predetermined over-limit values, specifically for copper, zinc, and silver, were automatically assayed using conventional assay procedures.  For each of these samples a 5 g sub-sample was split and assayed using conventional fire assay procedures with an atomic absorption finish (‘FA/AA’).  Following receipt of the analytical and assay results, 317 sample pulps were shipped to ALS Laboratories for check analyses and/or assays.
