" or the "
Company
")
(TSX-V: DEFN) is pleased to announce completion of an Updated Mineral Resource Estimate
("
MRE
") with respect to its 1,708 hectare (4,220 acre) Wicheeda Rare Earth Element (REE) Project
located near
Prince George, British Columbia
(BC),
Canada
.
Highlights:
49% increase in overall tonnage
1
of Updated Wicheeda REE Project MRE based on the
results of 2019 diamond drilling of 13 holes totaling 2,005 metres;
30% increase in overall average grade
1
, in part though the incorporation of potentially
economically significant praseodymium not previously estimated;
Conversion of 4,890,000 tonnes to Indicated Resources
1
previously defined as Inferred;
Increased Inferred Resources by 730,000 tonnes
in comparison to Defense Metals Initial
Wicheeda MRE
1
; and
Potential for expansion
of the Wicheeda Deposit to the north and west in the down plunge
direction.
The updated Wicheeda MRE comprises an
Indicated Mineral Resource of 4,890,000 tonnes
averaging 3.02% LREO (Light Rare Earth Elements),
in addition to
Inferred Mineral Resource
of 12,100,000 tonnes averaging 2.52% LREE
reported at a cut-off grade of 1.5% LREE
(sum of
cerium (Ce), lanthanum (La), neodymium (Nd), praseodymium (Pr), and samarium (Sm); in addition
to niobium (Nb) percentages). The lower cut-off grade was established based on consideration of
metal price and concentrate payable, metallurgical recovery, and operating cost assumptions and
uncertainty. The resource, constrained by applying a conceptual Lerchs-Grossman (LG) pit shell, is
provided in
Table 1
below, which includes a review of the MRE at a range of cut-off grades.
Craig Taylor

"With the release of our updated
Mineral Resource Estimate Defence Metals has delivered on another significant milestone in
advancing what management believes is one of the most compelling undeveloped rare earth
element assets in
North America
. Our
successful 2019 drill campaign has resulted in a significant
expansion and increased level of confidence in the mineral resources of the Wicheeda REE
Deposit, which remains open to the north and west."

accordance with CIM Definition Standards and NI 43-101, with an effective date of
April 29,
2020
.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic
viability
. There has been insufficient exploration to allow for the classification of the indicated
and inferred resources tabulated as a measured mineral resource, however, it is reasonably
expected that the majority of the indicated and inferred mineral resources could be upgraded
to indicated or measured mineral resources with continued exploration. There is no guarantee
that any part of the mineral resources discussed herein will be converted into a mineral
reserve in the future.
Mineral Resources are reported at a cut-off grade of 1.5% LREE (light rare element, sum of
Ce, La, Nd, Pr; in addition to Nb, and Sm %'s).
The cut-off grade includes the following considerations:
Metal prices of: Ce =
US$2.11
/kg; La =
US$2.10
; Nd =
US$51.44
; Pr =
US$561.9
; Nb =
US$30.29
; Sm =
US$2.07
;
Exchange rate of
0.75 US$
:C$;
Concentrate production grades of: Ce = 23.7%; La = 17.9%; Nd = 5.3%; Pr=1.8% ; Nb =
0.5%; Sm = 0.01%;
Concentrate payable of 80%;
Hydromet refining charges of
C$0.70
/kg concentrate;
Offsite Transport costs of
C$180
/t;
No royalties have been applied (A 2% royalty payable to the Vendor adds LREE 0.02% to the
cut-off item which is beyond the accuracy of the cut-off item and has no material impact to the
resource estimate.
The resources are constrained by resource pit shell generated using the following inputs:
Mining cost of
C$3.50
/t;
Waste mining costs of
C$3.25
/t;
Process Costs of
C$40
/t (includes
$10
/t for transporting from pit to mill);
G&A Costs of
C$7
/t
Process Recoveries: Ce = 85.7%; La = 85.7%; Nd = 85.7%; Pr = 85.7%; Nb = 57.0%;
Sm = 85.7%
Overall pit slope angles of 45
o
.
The resource is classified according to the CIM "Estimation of Mineral Resources and Mineral
Reserves Best Practice Guidelines" dated
November 29
th
, 2019 and CIM "Definition Standards for
Mineral Resources and Mineral Reserves" dated
May 10
th
, 2014. A NI 43-101 technical report
disclosing the Updated Wicheeda REE Project MRE will be filed on
SEDAR
within 45 days.
Factors that may affect the estimates include: metal price and concentrate payable assumptions,
changes in interpretations of mineralization geometry, continuity of REE mineralization zones,
changes to kriging assumptions, metallurgical recovery assumptions, operating cost assumptions,
confidence in the modifying factors, including assumptions that surface rights to allow mining
infrastructure to be constructed will be forthcoming, delays or other issues in reaching agreements
with regulatory authorities and stakeholders, and changes in land tenure requirements or in
permitting requirements.
Updated Mineral Resource Estimate Details
The drillhole database used to calculated the MRE is comprised of 27 exploration diamond drillholes
completed in 2008 and 2009 by previous operators (14 holes totalling 2,244 metres) and in 2019 by
Defence Metals (13 holes totalling 2,005 metres), containing a total of 1,315 drill core samples
analyzed for REE by multi-element fusion Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
and pressed pellet X-ray Fluorescence (XRF) methods. Sample intervals ranged from 0.5 to 7.1
metres in length, with 96% of the intervals having a length of 3.0 metres or less.
The Wicheeda 3D geological model created by APEX Geoscience Ltd. integrates assay and
geological data collected from diamond core drilling; surface geologic mapping; soil geochemical;
and airborne magnetic; and radiometric geophysical surveys. Based on these data, the Wicheeda
REE Deposit is modelled as a southeast-trending, north to northeast dipping composite layered
syenite-carbonatite sill complex having dimensions of approximately 400 metres north-south by 100-
250 metres east-west. Diamond drilling data supports the interpretation of a moderately north-
northeast dipping, shallowly north plunging, layered sill complex having low REE grade syenite at its
base, overlain by transitional intermediate REE grade hybrid xenolithic-carbonatite (fenite), and
finally relatively higher REE grade dolomite-carbonatite rocks, which form the main body of the
Wicheeda REE Deposit outcropping at surface. Based on the drill results to date, the eastern margin
of the Wicheeda REE Deposit is marked by a north-northwest trending sub-vertical lithologic contact.
This layered sill complex occurs within an unmineralized limestone waste rock. There remains the
potential for expansion of the Wicheeda Deposit to the north and west in the down plunge direction
where 2019 drilling indicates the deposit remains open.
The dolomite-carbonatite, xenolithic-carbonatite, syenite, and limestone have different mineralization
controls and styles that contain varying grades of REE. Therefore, these four rock types modelled
within the 3D geological model are used to define the estimation domains used to calculate the
MRE. The 3D rock model was used to discretize drillhole data and the volume of the deposit into
distinct zones (domains) that were treated separately during exploratory data analysis and resource
estimation.
Length-weighted averaged composites of 3 metre core length, restricted to each rock type, were
calculated and used for exploratory data analysis and resource estimation. Composites were
capped to a specified maximum value for each estimation and metal of interest. Composites within
each domain are evaluated to determine appropriate capping levels for each estimated metal. Only
the dolomite-carbonatite estimation domain within the east fault-block contains enough data to allow
the modelling of a robust variogram for each of the metals of interest. The modelled variograms from
that domain are scaled to the variance of the composites within the other estimation domains; these
scaled variograms were used for resource estimation.
A block model with a regularized cell size of
3 m
(X) by
3 m
(Y) by
3 m
(Z) was used to estimate
grade into for each metal for the MRE Ordinary Kriging (OK). The percentage of the volume of each
block below the bare earth surface and within each rock type was calculated using the 3D geological
model and a 3D surface model. The search ellipsoid size used to estimate each metal was defined
by the modelled variograms, which range from 100 to 140 metres in the major axis, 80 to 100 in the
minor axis, and 11 to 15 metres in the vertical axis. Block estimation employed varying anisotropy,
which uses different rotation angles to define the principal directions of the variogram model and
search ellipsoid on a per-block basis. Blocks within estimation domains are assigned rotation angles
using a modelled 3D mineralization trend surface wireframe, which allows structural complexities to
be reproduced in the estimated block model. A total of 795 density measurements were used to
assign density to each block based on its dominant rock type. Density values applied to the block
model were: 2.94 g/cm
3
(dolomite-carbonatite), 2.87 g/cm
3
(xenolithic-carbonatite), 2.70 g/cm
3
(syenite), and 2.74 g/cm
3
(limestone). The final grade estimates are validated visually by comparing
each block's metal estimates to the raw downhole assay data and statistically by generating swath
and volume-variance plots.
