Vancouver, British Columbia – May 13, 2020 : Defense Metals Corp. (“Defense Metals” 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.


  • 49% increase in overall tonnage1 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 grade1, in part though the incorporation of potentially economically significant praseodymium not previously estimated;

  • Conversion of 4,890,000 tonnes to Indicated Resources1 previously defined as Inferred;

  • Increased Inferred Resources by 730,000 tonnes in comparison to Defense Metals Initial Wicheeda MRE1; 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, President and CEO of Defense Metals comments: “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.”


Notes for Resource Table:

  • The Mineral Resource Estimate was prepared by Steven J. Nicholls (M AIG), and Warren Black, M.Sc., P.Geo. of APEX Geoscience Ltd., with geological modelling contribution by Kristopher J. Raffle. P.Geo. of APEX Geoscience Ltd. and a director of Defense Metals, in 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 45o.

The resource is classified according to the CIM “Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines” dated November 29th, 2019 and CIM “Definition Standards for Mineral Resources and Mineral Reserves” dated May 10th, 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.


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/cm3 (dolomite-carbonatite), 2.87 g/cm3

(xenolithic-carbonatite), 2.70 g/cm3 (syenite), and 2.74 g/cm3 (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.
