in the News: Coast Copper (TSXV: $COCO.V) Makes New Copper-Gold Discovery at
Empire: 7.18 g/t Gold and 3.17% Copper over 16.3 m at Raven Bluff Target; @CoastCopper_
Vancouver, BC,
February 2, 2022- Investorideas.com Newswire,
Coast Copper Corp. (TSX-V: COCO) announces
assay results for the second batch of samples from its initial 19 drillhole
(2,346 metre (“m”)) core drilling program completed in December 2021 on
its optioned Empire Mine Property (the “Property”); see news releases
dated December
20, 2021 and January
25, 2022. Results reported in this news release are
from two drillholes and one partial drillhole (MW21-015, partial 016 and 017)
located in the Raven Bluff and Raven Pit approximately 200 m north of the
past-producing Merry Widow magnetite iron ore open pit mine (see Figure 1).
Drill highlights include 7.18 grams per tonne (“g/t”) gold (“Au”) and 3.17%
copper (“Cu”) intersected over 16.3 m at Raven Bluff: and 6.2 g/t Au
over 1.67 m at Raven Pit. See Table 1 for full list of highlights.

The objective of drilling at the Raven Bluff
and Raven Pit targets was to test parts of the Property that, despite numerous
recommendations made over the years since 1988 by consultants, had remained undrilled.
The 2021 drillholes encountered significant copper and gold intercepts and more
drilling is clearly warranted.
At Raven
Bluff (see Figure 1) a detailed review of historical records, compilation
of previous geological mapping and our own site inspections indicated that
sulphide mineralization was more likely associated with north-northwesterly
trending greenstone dykes within a 200 m x 200 m area that has never been
adequately tested. Coast Copper’s drillholes MW21-015 & MW21-016 were
drilled as a preliminary test of this hypothesis and were successful in
intercepting semi-massive chalcopyrite and pyrrhotite bands, in core lengths up
to 16.28 m, associated with the margins of the greenstone dykes. These
sulphide-rich mineralized zones intercepted in hole MW21-015, occurring as deep
as 100 m below surface (see Figure 2 and Table 1), gave assays of up to 7.18
g/t Au, 3.17% Cu over 16.28 m. Assay results have only been partially completed
for drill hole MW21-016, which was drilled below drillhole MW21-015 returned
initial assay results up to 0.55 g/t Au and 1.06% Cu over 12.04 m and
suggestive that the mineralization at Raven Bluff persists to depth. Detailed
controls to mineralization are still being determined and complete assay
results are awaited for the rest of MW21-016.

prices used in CuEq and AgEq calculations are as follows: Gold $1750/oz, Silver
$23.00/oz, Copper $4.20/lb and Cobalt $25/lb. Recoveries are assumed to be 100%
for the purposes of equivalent calculations.*** The AuEq formula used for
calculations is: AuEq g/t = Au g/t + (Cu % x 1.65) + (Ag g/t x $0.013) + (Co %
x $9.80).****The CuEq formula used for calculations is: CuEq % = Cu % + (Au g/t

Historical
records indicate that the 21 m wide, north-trending Raven magnetite deposit
with associated sulphides: pyrrhotite, pyrite, sphalerite and chalcopyrite was
mined in the Raven Pit during 1959. As a magnetite resource, its high
sulphide content made the Raven deposit uneconomic and after extracting about
22,000 tons, the Raven deposit was abandoned and later backfilled with waste
rock from the Merry Widow Pit (J. Lund 1966). A substantial body of massive
pyrrhotite, with lesser chalcopyrite and pyrite (with gold and silver values
reportedly associated with these sulphides),
cut by late occurring calcite-sphalerite veins, was described as occurring near
the Raven Pit’s eastern boundary².
Coast Copper’s drillhole MW21-017 (see Figure 2 and Table 1 and 2) is the
first ever drillhole to be drilled under the backfilled Raven Pit and, after
passing through 30 metres of waste dump material, immediately cored into 4.70 m
of semi-massive pyrrhotite and chalcopyrite that assayed 6.2 g/t Au over 1.67 m
followed by 2.03 m grading 0.36 g/t Au and 0.28% Cu. Deeper in the hole, other
bands of massive magnetite of up to 8. 6m were encountered. It is important to
note that it appears that this drillhole clipped the top of the zone and now
that the historical pit and mineralization has been re-located subsequent
drillholes can be properly located to test the entire reported widths of this
> 20 m wide zone.
Adam
Travis, Coast Copper’s CEO commented, “We have now reported two new gold
discoveries at Raven Bluff and Raven Pit, one
of ten main target areas on the Property, to go along with our significant
copper and gold results released last week, which I would encourage everyone to
read. Our drill success at Raven Bluff opens up at least a 200 m x 200 m target
area. These new discoveries confirms our belief that additional areas on the
Property are prime exploration targets for new copper and gold discoveries as
previous operators either focused on the mining of magnetite or drilling in the
Merry Widow Pit. Even within the Merry
Widow area which is a small portion of the overall Property zones such as South
Pit, Lower Marten and Whiskey Jack have not been drilled. This is also another
step forward in proving that the Empire Mine Property covers a large district
scale potential with multiple target types (magnetite, copper/gold and zinc
skarns, gold and copper veins, Iron Oxide Copper-Gold) that have seen little to
no modern exploration. We look forward
to adding this drill core to our display at the AMEBC Roundup conference
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 drill core
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.

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).
