Sitka

(TSX-V:SIG)
(FSE:1RF)
(OTCQB:SITKF)
is
pleased
to
announce
additional
positive
assay
results
from
the
Rhosgobel
discovery
at
its
100%
owned,
road
accessible
RC
Gold
Project
located
in
the
Yukon’s
prolific
Tombstone
Gold
Belt.
The
mineralized
footprint
of
the
Rhosgobel
discovery
is
rapidly
expanding
with
visible
gold
observed
in
16
of
the
22
holes
drilled
to

over
approximately

km

represented
by
the
>500

gold-in-soil
anomaly
(see
Figure

To
date,
results
for
just
six
of
the
22
diamond
drill
holes
completed
at
Rhosgobel
have
been
received
with
all
six
holes
returning
>100
gram-metres

in
this
release
(see

and

To
date
6,438
of
the
planned
10,000
metres
of
drilling
have
been
completed
at
the
Rhosgobel
discovery
as
part
of
the
30,000

fully

diamond
drill
program
currently
underway
at

"Drilling
at
Rhosgobel,
which
is
the
largest
intrusion
within
the
Clear
Creek
Intrusive
Complex,
continues
to
confirm
that
we
have
made
a
very
significant
gold
discovery,”
said
Cor
Coe,
Director
and
CEO
of
Sitka
Gold.
“We
are
still
at
an
early
stage
of
drilling
at
Rhosgobel
yet
we
already
have
multiple
occurrences
of
visible
gold
observed
in
several
drill
holes
that
are
located
along
a
900
metre
strike
of
the
interpreted
zone,
with
the
first
six
diamond
drill
holes
ever
drilled
on
this
target
all
returning
intersections
that
are
greater
than
100
gram-meters
(g/t*m)
of
gold.
The
potential
for
the
Rhosgobel
intrusion
to
host
a
large,
multi-million
ounce
gold
deposit
similar
to
other
known
deposits
in
the
Tombstone
Gold
belt
is
becoming
more
evident
with
these
recent
resu
lts.
The
gold
endowment
of
the
RC
Gold
Project
is
growing
rapidly,
driven
by
our
latest
discovery
at
Rhosgobel
alongside
our
known
deposits
at
Blackjack
and
Eiger,
which
both
remain
open
for
expansion.
With
advanced
drill
targets
at
Saddle,
Pukelman-Contact,
and
the
Bear
Paw
Breccia,
plus
a
strong
pipeline
of
additional
targets
and
grassroots
potential
across
our
431-square-kilometre,
road-accessible
claim
block,
the
potential
for
further
resource
growth
at
RC
Gold
is
significant."

The

which
had
not

The

by
a
large
2.0
km

1.5
km
gold-in-soil
anomaly
which
covers
the
central
part
of
the
intrusion.
All
holes
have
intersected
reduced

gold
(RIRGS)
style
mineralization
including
centimetre-scale,
sheeted,
quartz
veins
and
larger,
metre-scale
quartz,
and
quartz-tourmaline
veins
(and
breccias)
cutting
the
feldspar

intrusion.
Multiple
occurrences
of

have
been
observed
in

RHOSGOBEL
DRILLING
To
date,
22
holes
totalling
approximately
6,438
m
have
been
completed
at
Rhosgobel.
All
holes
drilled
have
intersected
significant
reduced
intrusion-related
gold
(RIRGS)
style
mineralization
including
centimetre-scale,
sheeted,
quartz
veins
and
larger,
metre-scale
quartz,
and
quartz-tourmaline
veins
(and
breccias)
cutting
the
feldspar
megacrystic
quartz
monzonite
intrusion.
Visible
gold
has
been
observed
within
all
styles
of
veins
and
is
often
associated
with
bismuthinite,
scheelite,
and
molybdenite
(see
Figure
4).
Drilling
to
date
has
traced
mineralization
over
a
strike
length
of
approximately
900
metres
within
a
large
2.0
km
x
1.5
km
surface
signature
represented
by
a
gold-in-soil
anomaly
with
values
up
to
>500
ppb
(Figure
3).
The
mineralization
at
Rhosgobel
remains
open
in
all
directions.
The
first
six
diamond
drill
holes,
including
the
two
discovery
holes
drilled
in
2024,
have
all
intersected
>100
gram-metres
gold
(g/t
Au*m).
DDRCRG-25-006
returned
166.0
m
of
1.14
g/t
gold
from
surface
including
8.0
m
of
4.86

gold
from
13.0
m.
Assays
from
DDRCRG-25-004
returned
238.0m
of
0.6
g/t
gold
from
surface,
including
20.1
m
of
1.02
g/t
gold
from
surface,
18.9

g/t
gold
from

were
drilled
from
the
same
locations
as
Holes

and
005
on

approximately
50

001
and

which
returned
164.8
metres
of
0.82
g/t
gold
from
9.1
metres
including
119.0
metres
of
1.05

gold
from
30.0

and
173.3

from

respectively

While
visible
gold
observations
are
very
encouraging
and
confirm
the
presence
of
gold
mineralization,
they
are
not
intended
to
imply
potential
gold
grades.
Gold
assays
will
be
published
after
they
are
received
from
the
lab
for
mineralized
intervals
in
which
visible
gold
particles
were
noted.
