CEO
Statement
Brandon
Macdonald, CEO, stated
"These
results are a great way to
finish the 2019 drilling
at Macmillan
Pass. I had
previously stated
that our first hole
NB19-001
was
the
best ever
drilled at Boundary
and now
we have eclipsed that with NB19-002. This hole is even better
and
clearly demonstrates zones of
very
high grade
within a
very broad interval which points to the large size and
grade
potential
of Boundary Zone. These
results,
along
with recent drilling success at Tom North and End
Zone, have
potential
to
meaningfully
expand
on our
current resource. With all the data in
from the summer program, we will
now
fully
evaluate the results and consider the best path forward to advance
the project. Clearly
we have
some potential levers to
improve economics after our excellent results from
the
2018
and 2019
campaigns."
Boundary
Zone Potential
No
mineral resource has been estimated for Boundary Zone
yet
and the
zone is not included in the current mineral resource estimate for
the property (described in Fireweed news release dated January 10,
2018). Boundary Zone has potential to be
mined in an open
pit
with a
low strip ratio and to be upgraded
through low cost, pre-concentration
ore
sorting processes
(see
below).
Recent drill results at Boundary Zone along with Tom North Zone and
End Zone (see Fireweed news releases dated September 10, 2019, and
November 15
and 29, 2018) represent potential for
expansion
of the large
current
mineral resources and improvement of
Macmillan
Pass project economics
described in the current Preliminary Economic Assessment (PEA) (see
Fireweed news release dated May 23,
2018).
Boundary
Zone Background
Historic
drilling of 24 holes
at
Boundary Zone indicates
the
presence of a large
bulk
tonnage
zone of zinc (-lead-silver)
mineralization
potentially suitable
for open pit mining. Known
mineralization
is
spread
over an area almost
two
kilometres long and 200 to 800 metres wide. Mineralization
drilled
in a
central area is
350
metres long and has a
true
thickness of up to 250 metres
with
historic drilling grades averaging 2.0
-
2.5% zinc4
that
include multiple
higher
grade intervals
closer to
surface similar to the hole
reported in this news release (see
Figures 2 & 3, Tables 1
&
2
and
Fireweed news release dated November 6,
2018).
Higher
grades near surface are
favourable for
potential open pit mining
economics. The zone
has
been
drilled up to 285
metres
down dip and remains open to depth
and along trend for further exploration. Boundary
Zone
mineralization
consists of sphalerite-siderite-pyrite
and minor galena in veins,
stockworks,
disseminations, and as
replacement
of matrix
and clasts within
coarse
clastic rocks.
The
2019 Boundary
drill
program was designed to infill a gap in historic
drilling (see Figure
2) and obtain
a
bulk
sample
for larger
commercial-scale ore sorting and
metallurgical test
work.
Drill
hole NB19-002, reported in this
release, was
collared
45
metres
from a
historic hole to obtain adequate
comparable material for the test work.
On
October 16, 2019, Fireweed reported results from
Boundary Zone drill hole NB19-001
in which
true widths were
reported
as pending. With results
from this
news release and additional interpretation, updated and
revised estimated
true
widths for drill hole NB19-001
have now
been
included
in Table 3.
Note
that NB19-001 and NB19-002
were collared in mineralization, so these holes did
not intersect the entire
zone, and the
true
width of Boundary Zone may be
greater
than the intersections reported in this release.
Boundary
Zone Ore Sorting Tests
Initial
ore
sorting test results for Boundary Zone indicate
mineralization is potentially amendable to low cost
state-of-the-art
X-Ray
Fluorescence
("XRF")
ore
sorting technology
(see
Fireweed news release
dated
July 31, 2019). These test results rejected 50-70% of the waste
material (30-50% mass pull), while
recovering
80-85% of the zinc.
In practical terms,
these results show potential to
upgrade mill
feed
from the test feed grade
of 2.5%
zinc
to
approximately
5%
zinc
with
recovery of 80-85% of the zinc at low
cost. Core collected from
the two 2019
Boundary
holes
will be used to carry out commercial-scale ore sorting
tests
and
metallurgical tests. If the tests
confirm the preliminary ore sorting
results, the Boundary Zone has the potential to significantly
improve the PEA economics of the Macmillan Pass Project.
2019
Drill Program
The 2019
drill program is
complete
and with
this news release, all 2019 drill
results
have now been reported. A total of 16
diamond
drill holes
were
drilled
for a
total of 2,357 metres
with
the successful
goals
of expanding and upgrading known
zones of mineralization at
Boundary, Tom West and Tom
East, as well as testing
new exploration targets such as Tom
North. Summary descriptions
of drill hole
collar
data, field
results
and
observations are provided in
Tables 4 and
5.
Access
Road Update
Access to
the project site is via Yukon Highway 6 (aka the North Canol Road)
and an airstrip on the property. As described in the
PEA study (see Fireweed news
release May 23, 2018
and
PEA
report
filed
on
www.sedar.com), any future mining
operation will require upgrading of the road
to accommodate more traffic.
Fireweed
is
pleased to report that during the past summer the
Yukon Department of Highways and
Public Works carried out
additional
work on
the road which included replacement of three more
bridges
and various road repairs.
Three additional new
prefabricated
bridges have also been
delivered to the start of the
road and
are
available
for installation next
year. The
continuing
active
support of the Yukon government on the Macmillan Pass
Project is but one indication
of why Yukon is a top
10 mining
investment jurisdiction in the world as designated by the
Fraser Institute.
Notes
on sampling and assaying:
The drill
core logging and sampling program was
carried
out under a rigorous quality assurance / quality control program
using industry best practices. Drill intersections
in this
release are all
HQ3 (split tube) size
core (61.1 mm / 2.4-inch
diameter) with recoveries typically above 85%. After drilling,
core was
logged
for geology, structure and geotechnical characteristics, marked for
sampling, and photographed on site. The cores for analyses
were
marked
for sampling based on geological intervals with individual samples
1.5 metres
or less in length. Drill core
from the
Boundary Zone was
cut
lengthwise
into quarters
with a
core saw;
a
quarter-core
was
sent for
assays reported in this
news release, two quarter
core
samples were collected for ore sorting and metallurgical test work,
and the
fourth
quarter
is stored
on site for reference. A total of 5% assay
standards or blanks
and
5% core
duplicates are
included
in the sample
stream as a quality control
measure and reviewed,
after analyses are
received.
Standards
and blanks in
2019
drill
results to date have been
approved as acceptable.
Duplicate
data add to the long-term estimates of precision for assay data on
the project and precision for
drill
results reported is deemed to be within
acceptable levels. Samples
were
sent to
the Bureau Veritas preparation laboratory in Whitehorse,
Yukon, where the
samples were
crushed
and a 500 g split
was pulverized to 85%
passing 200 mesh size pulps. Clean crush
material was passed through the
crusher and clean silica was pulverized between
each sample. The pulps were
then sent
to the Bureau Veritas laboratory in Vancouver, B.C. and analyzed by
1:1:1 Aqua Regia digestion followed by Inductively Coupled Plasma
Mass Spectrometry (ICP-ES/ICP-MS) multi-element analyses (BV Code
AQ270). All samples were
also
analyzed for multiple
elements by lithium borate
fusion and X-ray fluorescence
analysis (XRF) finish (BV Code LF725). Over-limit Pb (>25.0%)
and Zn (>20.0%)
were analyzed by
lithium borate fusion with XRF finish (BV Code LF726).
A subset
of four high grade
Zn (>45%)
samples
have
been re-analysed
by titration assay (BV Code
GC816)
and
all samples over
40%
Zn have been
re-analysed
by
lithium
borate fusion with XRF
finish
(BV Code
LF726) to confirm
the
very
high
values.
Silver is
reported in this news release by method AQ270, and zinc and lead
are reported by LF725 or LF726. Bureau Veritas (Vancouver) is an
independent, international ISO/IEC 17025:2005 accredited
laboratory.

Footnotes:
1.
The
sample for drill hole NB19-002 interval 145.65-146.53 metres was
reported as >60% Zn by the laboratory who are working on
carrying out a special titration assay in order to report a final
value which was not yet available at the time this news release was
issued. A
value of 60% Zn was used for purposes of related interval
calculations in Tables 1 and 2.
2.
The
average bulk density of the mineralized rock in NB19-002
is
3.06
t/m3.
3.
Estimation
of true widths of intervals in Tables 1, 2 and 3 is based on
preliminary geological interpretation of historic and new drilling
data. Mineralization overall at Boundary Zone appears to follow
lithological units which have a consistent ESE-WNW orientation with
a moderate northerly dip. However, high grade veins are oriented
ESE-WNW with steep northerly dips which were used to estimate the
individual true widths (see Figure 3).
4.
Historic
results for the
Boundary Zone reported
in this news release are taken from historic reports prepared by
previous operators.
Neither
the Company or the Qualified Person has done sufficient work to
verify these results and
therefore these results should not be relied upon.
The
Company is
including them for information purposes to
explain the basis for the exploration target and
reasons for drilling.
