Coast Copper Corp. announced the first batch of assay results from its initial 19 drillhole (2,346 metre) core drilling program completed in December 2021 on its optioned Empire Mine Property (the ‘Property'). Results reported are from eleven drillholes (MW21-001 to MW21-009, MW21-013 and MW21-014) that were drilled in and around the past-producing Merry Widow magnetite iron ore pit, which is one of ten main target areas on the property. Past mining by Empire Development Ltd. (1957-1967) at the Merry Widow Pit noted pyritic and copper sulphide skarn zones that forms around the margins of magnetite bodies, fault zones and greenstone dykes but avoided them to minimize contaminating their magnetite concentrate.

These sulphide zones were later (1980s) learned to also contain significant copper and gold and yet to this day have never been fully explored. The objectives of the December 2021 drill program was to conduct an initial one-month best practice, modern drill program prior to Christmas on some of the many shallow sulphide targets near the Merry Widow Pit and 2008 Grand Portage Resources. This work was done to infill, confirm and possibly extend mineralization, to expedite sampling and assaying, and to learn both logistically and geologically how to plan for larger programs in 2022.

These objectives were met, and the assay results provide positive reconciliation with historical drilling and demonstrate the existence of broad zones of mineralization containing significant copper and gold intercepts. Coast Copper will continue to update its geological interpretation and modelling and will report additional assay results once received. Photos of select drill core will be available on the Coast Copper website under the Empire Mine Property tab.

The 2021 drill sample collection was supervised on-site by Coast Copper personnel and sub-contractors who inserted certified standards, blanks, and field duplicates consisting of quarter core samples into each batch of samples at regular intervals. QA/QC samples account for 8% of the total samples sent to the labs.  Samples were sealed on site and shipped to MSALABS in Langley, British Columbia for analysis.  Samples were prepared by crushing the entire sample to 70% passing -2mm, riffle splitting of 1kg and pulverizing the split to better than 85% passing 75 microns. MSALABS also conducts a rigorous QA/QC policy by inserting standards, blanks and conducting pulp duplicates on certain drillcore intervals. All samples were analyzed by 48 element ultra-trace 4-acid ICP digestion.

Copper assays >10,000 ppm and Ag assays >100 g/t were reanalyzed with an Ore Grade method.  The analytical results are verified with the application of industry standard Quality Assurance and Quality Control (‘QA/QC') procedures. The gold assays were determined by 30g fire assay with AAS finish method which reports in parts per million (‘ppm; equivalent to g/t).  Any samples greater than 10.0 g/t gold were re-analyzed by fire assay method with a gravimetric finish. Iron ore analysis was determined by borate fusion and XRF finish.
