Coast Copper Drills 4.1 m of 5.66% CuEq Near Surface from Merry Widow Zone on Empire Mine Property
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 Resources1. 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.
Merry Widow Zone: 2021 Core Drill Exploration Program Highlights
- Quick turnaround: financing closed on November 29, 2021 , drilling finished on December 20, 2021
- Coast Copper's first core drilling of the Merry Widow Zone; one of ten main target areas on the Property returned significant copper, gold, and magnetite results (see following Tables 1 to 3 and Figure 1).
- Broader intercepts included: MW21-004: 1.67 grams per tonne ("g/t") gold ("Au") and 0.22% copper ("Cu") over 34.92 metres ("m"); MW21-007: 1.84 g/t Au and 0.20% Cu over 39.54 m; MW21-008: 1.63 g/t Au and 0.46% Cu over 42.77 m and MW21-013: 1.22 g/t Au and 0.39% Cu over 51.06 m.
- High-grade intercepts included: MW21-004: 8.15 g/t Au and 0.57% Cu over 4.86 m; MW21-007: 18.00 g/t Au and 1.55% Cu over 3.23 m; and MW21-008: 4.69 g/t Au and 0.34% Cu over 10.80 m.
- Although iron-hosting magnetite zones were not targeted in this program, many zones were intercepted at margins of the historical Merry Widow magnetite iron ore workings indicating potential to increase the magnetite resource (see Table 2).
- Half of the initial drillholes terminated prematurely in underground workings often ending in mineralization, for example MW21-003 intersected 1.18 g/t Au and 0.36% Cu over the final 3.30 m and MW21-005 intersected 8.83 g/t Au and 0.37% Cu over the final 1.62 m.
- First core drill program on the Property to geologically log, photograph, complete systematic magnetic susceptibility and specific gravity measurements, sample the entire length of the drill core, properly assay it for magnetite iron ore and securely store it in Port Hardy, as no permanent record or drill core remains from previous programs.
Adam Travis, Coast Copper's CEO commented, "We are very pleased to report our first batch of assay results from our first drill program at the Empire Mine Property within one month of completing the program. This drilling has confirmed, infilled and extended copper, gold and magnetite mineralization with silver and cobalt credits around the historical Merry Widow past producing iron ore open pit mine. These drill results have returned significant copper-gold intercepts some which could have been longer as many holes terminated in mineralization before ending in underground workings. We are also documenting and assaying magnetite intervals which could add to the potential value of the project. We look forward to receiving more assay results from the Raven and North Notch Zones located approximately 200 m north of the Merry Widow Pit and from two drillholes completed at the end of the program approximately 1.2 kilometers to the east. We look forward to displaying our drillcore at the AMEBC Roundup February 3rd and 4th, 2022 in Vancouver, B.C."
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.

QA/QC Statement on Assay Results
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.

Cautionary Notes Related to this News Release and/or maps
- NI 43-101 Technical Report: Giroux, G.H., & Raven, W. (November 30, 2008). Technical Report on the Copper Gold Resources for the Merry Widow Property. Filed on SEDAR January 22, 2009. The 2008 Grand Portage resource estimate was completed by Gary H. Giroux, P.Eng, MASc, of Giroux Consulting Ltd. in Vancouver, B.C. The estimate was based on a 3D geological model integrating 4,448 metres of diamond drilling of 43 drill holes, 2,290 assays, with 104 down-hole surveys collected between June and December 2006. The resource was reported utilizing gold cut-off grades ranging from 0.10 g/t to 3.00 g/t gold, as more particularly set out in the report. A complete copy of the report is available on Grand Portage's public filings on SEDAR (www.sedar.com). A gold cut-off grade of 0.50 g/t gold was selected as representing one possible mining scenario. For the purposes of the calculations, lognormal cumulative frequency plots were used to assess grade distribution to see if capping of high values was required and if so at what levels. For all elements, capping levels were established based on the individual grade distributions as follows: Gold -- a total of 18 gold assays were capped at 32.0 g/t gold, Silver --a total of 9 silver assays were capped at 165 g/t silver, Copper -- a total of 7 assays were capped at 11.7% copper, Cobalt -- a total of 5 assays were capped at 0.48% cobalt, Iron -- all iron assays were capped at 50% iron (the analytical detection limit).
