ArcWest Exploration Inc. Discovers New Gold and
Copper Enriched Volcanogenic Massive Sulfide Zone at
Todd Creek Project
Vancouver, British Columbia--(Newsfile Corp. - October 1, 2019) - ArcWest Exploration Inc. (TSXV: AWX) ("ArcWest") is
pleased to announce the discovery of a previously unknown zone of polymetallic volcanogenic massive sulfide (VMS)
mineralization on its 34,764 hectare Todd Creek Project, located 30 km northeast of Stewart in B.C.'s Golden Triangle.
The
newly discovered VMS West zone is located about 400 meters west of the VMS East zone which was previously sampled in
2018 (see news release December 12, 2018). Highlights of the 2019 exploration program of the VMS Zones include:
Outcropping VMS mineralization discovered approximately 400 meters west of previously known mineralization at the
VMS East Zone has been traced over a distance of at least 400 meters north-south and remans open in both directions.
Sampling of the VMS West Zone has demonstrated significantly higher gold (Au) grades than previously sampled at VMS
East, including grab samples up to 2.05 grams per tonne (g/t) Au and 1.21% copper (Cu).
Additional 2019 sampling at VMS East demonstrates an overall strike length of over 900 meters, with strongly elevated
silver (Ag), lead (Pb) and zinc (Zn) values. Highlight 2019 grab sample results are included in the table below.
The outcropping mineralized zones comprise a small part of an undrilled >10 km long belt of gossans and highly
prospective upper Hazelton Group stratigraphy extending along the east side of Todd Creek.
Grab samples are selective by nature and may not be representative of actual grades or styles of mineralization across the
property.
ArcWest's President Tyler Ruks comments:
"Our 2019 mapping and sampling program at the Todd Creek VMS Zone continues
to expand the size and potential of this very significant and untested massive sulfide discovery.
With the discovery of the copper
and gold enriched VMS West Zone we have defined a useful metal zonation which represents a significant exploration vector in
VMS systems. Together with the numerous gossans extending along the east side of Todd Creek to the Smokin Zone 10
kilometers to the north, this extensive area of prospective upper Hazelton Group stratigraphy represents a new and virtually
unexplored suite of VMS targets in the Golden Triangle, a region known to contain world class VMS deposits such as Eskay
Creek and Granduc."
Outcropping bedded massive sulfides in the headwaters of Todd Creek were discovered in 2008 below a receding glacier.
Previous 1-2 meter channel samples of the zone returned grades up to 0.74% Cu, 1.35 g/t Au and 9.7% Zn. Mapping and
sampling by ArcWest in 2018 and 2019 has greatly expanded the prospective VMS stratigraphy with the extension of the
original discovery in the VMS East Zone and the new discovery,
VMS West. The VMS Zones are underlain by Hazelton Group
mafic volcanic and volcaniclastic rocks and marine sedimentary rocks. Bedded and locally laminated pyrite-chalcopyrite-
sphalerite-galena massive sulfide lenses are accompanied by strong chlorite-sericite, silica and carbonate alteration. Locally,
the volcaniclastics hosting the massive sulfides also contain angular clasts of massive sulfide, suggesting the likelihood of
multiple VMS horizons.
This has been confirmed by the VMS West discovery, located approximately 400 m to the west.
Sampling of the VMS West Zone confirms elevated Au, Ag and Cu grades as well as locally strong Pb and Zn. All 19 samples
collected in 2019 averaged 0.351 g/t Au, 8.6 g/t Ag, 0.64% Cu, 0.21% Pb and 1.03% Zn (median 0.258 g/t Au, 9.4 g/t Ag,
0.75% Cu, 0.04% Pb and 0.02% Zn; range <0.001-2.05 g/t Au, 0.02-14.1 g/t Ag, 0.002-1.37% Cu, 0.001-2.43% Pb, 0.003-
6.92% Zn). Sampling to date suggests that VMS West is Cu-Au enriched, whereas VMS East is more polymetallic in nature.
The
higher average Cu and Au values at VMS West are interpreted to signify a higher temperature style of VMS mineralization,
whereas the elevated Ag, Pb and Zn at VMS East may represent a more distal, lower temperature form of massive sulfides.
Outcropping polymetallic massive sulfide mineralization has now been documented on the property over an area >1 km long and
up to 800 meters wide.
The zone remains open in all directions and is untested by drilling.

Methods
Rock samples are of a reconnaissance nature, including chip, grab and select samples and may not be representative of a
larger volume of rock. The samples were analyzed by ALS Geochemistry of North Vancouver, British Columbia. They were
prepared for analysis according to ALS method Prep-31A: each sample was crushed to 70% passing -2mm and a 250g split
was pulverized to better than 85% passing 75 micron mesh. Gold was tested by fire assay with ICP-AES finish on a 30g nominal
sample (method Au-ICP21). An additional 35 elements were tested by ICP-AES using aqua regia digestion (method ME-
ICP41). Quality assurance and control (QAQC) is maintained at the lab and by ArcWest through rigorous use of internal
standards, blanks and duplicates.
