Coast Copper Samples and Extends High-
Grade Silver Over 1.5 km Strike at Sweeney
TSX.V: COCO
VANCOUVER, BC
,
Oct. 7, 2024
/CNW/ -
Coast Copper Corp. ("Coast Copper" or the
"Company";
(TSXV: COCO) is pleased to report high-grade silver assays from rock and soil
samples collected from a 2 square kilometer ("
km
2
") area on its recently acquired 15 km
2
Sweeney
property ("
Sweeney
" or the "
Property
") located approximately 135 kilometer ("
km
") southwest of
the town of
Houston
in the Central Interior of
British Columbia
("
BC
"). Sweeney is road accessible,
centrally located in the Huckleberry Mine Camp and is 7 km north-northwest of the past producing
Huckleberry Mine, 3 km west of Huckleberry Mines Ltd.'s Whiting Creek deposit and 8 km southeast
of the Berg Deposit owned by Surge Copper Corp
1
.
The Property includes the past-producing, epithermal vein-hosted, high-grade silver-lead-zinc-gold
("
Ag-Pb-Zn-Au
") Emerald Mine that ceased small scale production in 1968. The last recorded
exploration work on the project occurred in 2012 and included a modest trenching along trend and a
shallow diamond drill program perpendicular to the trend of the Miya Vein and demonstrated
shallow, high-grade Ag-Pb-Zn-Au and copper
("Cu")
over widths of 1-3 meters ("
m
") (drill intercept,
not true width) located within approximately
300 m
of the footprint of the Emerald Mine [see Coast
Copper news release of
September 3, 2024
]. No systematic or modern exploration program
appears to have been undertaken outside an area of 1 km
2
around the Emerald Mine, possibly due
to previous snow and ice cover.
Glacial retreat over recent years has improved overall ground access including newly accessible
areas located to the north and northwest of historically identified mineral occurrences. Coast Copper
completed initial work on the Property in early September which included the collection of 47 rock
and 34 soil samples (see Tables 1 and 2 and Figure 1 for selected results). Assay results indicate
that the main Ag-Pb-Zn trend
("Main Trend")
may now extend for
over 1.5 km
. Coast Copper is
also pleased to report identification of a new target area
("Northwest Ridge")
with high-grade Ag,
Pb, Zn and Cu values in soil samples.
Assay Highlights from the Main Trend (
Emerald- Bluff-Roymac-Rhine View and new extension "North
Bowl"):
Emerald:
composite rock samples returned
2.58 grams per tonne ("g/t") Au, 1,042 g/t Ag
and 37.8% Pb over
2.5 m
and
4.76 g/t Au, 980 g/t Ag, 1.10% Cu, 11.79% Pb and 15.45% Zn
over
1.5 m
.
Bluff
:
rock grab sample results include
197 g/t Ag, 8.91% Pb, and 1.08%
Cu.
Roymac to Rhine View
:
rock grab sample results include
1.71 g/t Au, 304 g/t Ag and 13.01%
Pb.
North Bowl:
rock grab sample results include
187 g/t Ag, 16.09% Pb and 4.26% Zn.
Highlights from the newly identified Northwest Ridge target area:
Northwest Ridge
(1,200-
1,700 m
northeast of Emerald Mine):
soil samples returned
up to 550
parts per billion ("ppb") Au, 63.23 parts per million ("ppm") Ag, 1,042 ppm Cu, >10,000
ppm Pb and 5,374 ppm Zn (see Table 2).
Adam Travis
, CEO comments: "
We're thrilled by these initial survey results at Sweeney.
Epithermal deposits of this kind tend to consist of multiple vein trends that may extend over square
kilometers and are often underlain by a porphyry deposit generating the mineralizing fluids. If
multiple high-grade silver-lead-zinc-copper-gold veins can be identified, the tonnage potential can
build rapidly. The key is to find and prioritize them for drill testing. The historical exploration
around the Emerald Mine was sparse and focused on small-scale production. It did not test the
Emerald Mine deposit to depth or the potential strike to the north which now appears to extend for
over 1.5 kilometers. Our discovery of high-grade silver-lead-zinc in rocks from 'North Bowl' and
very impressive silver-lead-zinc-copper and gold in soils taken along the 'Northwest Ridge' where
the glacier has receded, opens up a significant new area for extension and multiple vein potential
that merits systematic exploration including mapping, geophysics, sampling and potentially drilling.
Another known example where silver-rich historical epithermal projects have been successfully re-
visioned through modern exploration include the Silver Queen deposit
1
located approximately 50
kilometers to the east of Sweeney."
Fletcher Morgan
, Chair comments:
"
The Sweeney purchase and subsequent work program is a
great example of how Coast Copper is continuing to advance its generative mineral property
acquisition program and creating value for its shareholders. Completing inexpensive, fiscally
responsible field programs is a strategic priority for the Company in preparing for the continuing
market turn we are starting to see within the junior mining and exploration space."

Coast Copper Corp Sweeney Property Results News Release. NR24-12 Figure 1 (CNW
Group/Coast Copper Corp.)
Emerald Mine and Miya Vein Detail
Historical exploration was focused in and around the Emerald Mine where mining occurred
intermittently between 1951 and 1968. Historical underground development on the Emerald Vein
took place on four levels (6400, 6275, 6000 and 5400 levels), producing 83,493 ounces ("
oz
") Ag,
49 oz Au; 1,966,396 pounds ("
lbs
") of Zn; 1,689,449 lbs of Pb; 19,872 lbs of Cu; and 3,713 lbs of
cadmium from the milling of 8,293 tonnes of ore. Unclassified historical reserves were reported on
the Emerald Vein of 40,800 tonnes grading 355 g/t Ag, 8.23% Pb, 9.49% Zn and 1.13 g/t Au with
ore zones noted open to depth (see cautionary notes 2 and 3 regarding historical mining and
reserves).
No drilling or underground exploration work was completed on the Property between 1971-2011,
until a 2012 diamond drill program which focused on the Miya Vein (cross-cuts the north-south
trending Emerald Vein trend at 300 degrees) and consisted of 30 drillholes with an average depth of
52 m
, covering over
350 m
of strike length and returning gold values up to 7 g/t Au with high-grade
silver, lead and zinc over 1-
5 m
intervals
4
.
The 2012 drilling on the Miya Vein remains open to depth and along strike and was the last recorded
work on the Property.
The geological mapping undertaken in 2012 noted at least 40 occurrences where galena-sphalerite
and/or chalcopyrite were observed but never assayed (see Figure 1)
4
, further underlying the
potential of the Property.
Quality Assurance/Quality Control ("QA/QC") Procedures
Sampling completed on the projects in 2024 was supervised by on–site Coast Copper personnel and
sub-contractors who collected and tracked samples. Rock samples were collected in areas of
interest and noted as either in place grab, composite or chip samples and if not in place as float
samples. Soil samples were primarily collected from the weathered rock horizon along ridge crests
consisting of "C" horizon due to the recently unglaciated terrain. Fieldnotes, GPS locations and
photographs were taken at sample locations
The samples were sealed on site and shipped to MSA Labs in
Langley BC
for analysis. MSA Labs'
quality control system complies with global certifications for Quality ISO9001:2008. Soil samples
were dried and screened to 80 mesh and then analyzed in 20g samples with multi-element ICP-MS
Aqua Regia digestion (IMS-130 and IMS-131). Rock samples were dried and crushed to 70%
passing 2mm mesh and split to 250g samples which were pulverized to 85% passing 75μm and then
analyzed by 4-acid digestion with a ICP-MS finish (IMS-240). Gold was analyzed for by fire assay
30g sample with an AA finish (FAS-111).
Sweeney Rock
samples were analyzed for Gold by fire
assay with a ICP-ES finish on a 30g sample. Ag samples >1000 ppm were analyzed FAS-418. Lead
assays greater than 20% were completed with STI-8Pb.

About Coast Copper Corp.
Coast Copper's primary exploration focus is the Empire Mine property, located on northern
Vancouver Island, BC, which covers three historical open pit mines and two past-producing
underground mines that yielded iron, copper, gold, and silver. In 2023, Coast Copper launched a
generative program aimed at advancing its other properties in parallel with Empire. In 2024, Coast
Copper acquired two new projects bringing its total number of 100% owned projects in BC to six,
consisting of the mineral titles comprising the Empire Mine property, the Sully property located in
southeastern BC, the Knob Hill NW property located on northern Vancouver Island, the Home Brew
property located in central BC, its Sweeney property located in the central interior of BC and its
Scottie West
property located in the "Golden Triangle" of northern BC. Coast Copper's management
team continues to review precious and base metals opportunities in western North America.
