REE Stock News - Defense Metals (TSX-V: $DEFN.V) (OTCQB: $DFMTF) Updates Wicheeda Canada Light Rare Earth Element Deposit Geological Model

Advances Toward Updated Mineral Resource Estimate and PFS


Vancouver, British Columbia - March 6, 2023 ( Newswire, Mining / Metals / Green Energy Stock news) Defense Metals Corp. ("Defense Metals" or the "Company") (TSX-V:DEFN / OTCQB:DFMTF/ 35D: FSE) is pleased to report its technical team has completed updates to the Wicheeda Rare Earth Element (REE) Deposit 3D geological model. The geological model and resource estimation domain update, which incorporates over 10,000 metres of additional drilling within 47 diamond drill holes completed during 2021 and 2022 following completion of the Wicheeda Deposit preliminary economic assessment (PEA), is preparatory to updating the Wicheeda Deposit mineral resource estimate (MRE) and is an essential input to the planned pre-feasibility study (PFS).

Key Highlights of Updated Geological Model

  • Updated geological model and resource estimation domains incorporate over 10,000 metres of new drilling within 47 holes completed post-PEA (Figure 1).
  • New drilling designed to contribute to increase mineral resource confidence from inferred to indicated and measured categories and provide detailed pit-slope geotechnical drilling data for PFS purposes.
  • Advanced understanding and confidence in primary lithological and magmatic emplacement controls on mineralization within the Wicheeda REE carbonatite deposit.
  • Potential opportunities for mineral resources expansion, and late mine-life grade support within north area of Wicheeda Deposit.
  • Coordination of geological model, estimation domains and geometallurgy present positive implications for further REE recovery optimization.

Kristopher Raffle, P.Geo., Director of Defense Metals and a Qualified Person stated: "The updated Wicheeda REE Deposit geologic model incorporating of over 10,000 metres of new post-PEA drilling represents a significant Project milestone and culmination of two years' worth of focussed exploration. This drilling has yielded some of the longest and highest-grade drill intercepts to date on the Project and led to the discovery of a new zone of high-grade mineralization at depth that has the potential to positively impact an updated mineral resource estimate. We look forward to next steps including final geological model validation before proceeding to an updated mineral resource estimate, which we hope to carry forward into the planned PFS."

Geological Model Details

Diamond drilling during 2021 and 2022 comprising 47 diamond drill holes totalling 10,876 metres has now been incorporated into an updated geological model for the Wicheeda Deposit. Most of the post-PEA drilling was designed to increase mineral resource confidence from inferred to indicated and measured categories, define the northern terminus of the Wicheeda carbonate complex, and to provide detailed geotechnical and hydrogeological drilling data for advanced pit slope and mine design for PFS purposes.

The expansive 2021 and 2022 Wicheeda drill campaign resulted in some of the longest and highest-grade drill intercepts returned from the Project; including resource infill drill hole WI21-58 that returned 3.09% total rare earth oxide (TREO) over 251 metres, and WI22-68 yielding 6.70% TREO over 18 metres. Discovery of deep high-grade REE dolomite-carbonatite within the north area of the Wicheeda Deposit during the 2021 drill campaign yielding 3.17% TREO over 196 metres; including 4.29% TREO over 55 metres to a depth of 201 metres extending 30 metres below the resource pit shell (see Defense Metals news release dated March 2, 2022). This intercept, further delineated during 2022, is considered to offer significant potential for resource expansion and late mine-life resource grade support.

Post PEA drilling has resulted in a significant improvement in confidence and understanding of the primary lithological and magmatic emplacement controls on mineralization within the Wicheeda REE carbonatite deposit. This manifests as enhanced understanding of the role played by the volumetrically larger early syenite complex rocks, followed by the interpreted emplacement of late REE mineralized dolomite-carbonatite and attendant carbonatitic breccia zones that may represent early syn-carbonatite ground preparation exploiting pre-existing zones of structural weakness and/or a syn-carbonatite intrusion breccia halo.

The recognition that significant REE grades occur within dolomite-carbonate rocks, as coherent magmas within the core of the deposit, and as an extensive complex network of proximal syenite-carbonatite breccia zones has important geo-metallurgical implications that have been the focus of ongoing testwork facilitated by the extent of post-PEA diamond drill campaigns (see Defense Metals news release dated February 14, 2023).

The 2020 Wicheeda Deposit MRE was based on a total of 27 diamond drill holes totalling 4,249 metres of drilling during 2019 by Defense Metals and 2008 and 2009 by previous operators. Drilling during 2019 by the Company of 13 holes totalling 2,005 metres resulted in a 94% increase on a contained metal basis versus the Company's initial 2019 MRE (see Defense Metals news release dated May 13, 2020).

The updated PEA MRE based on the same drilling resulted in a further 36% increase on a contained metal basis in comparison to the 2020 MRE due to the estimation of additional economically significant medium and heavy REE's and a lower cut-off grade established based on consideration of TREO and concentrate payable, metallurgical recovery, and operating cost assumptions[1].

About the Wicheeda REE Property

Defense Metals 100% owned, 4,262-hectare (~10,532-acre) Wicheeda REE property is located approximately 80 km northeast of the city of Prince George, British Columbia; population 77,000. The Wicheeda REE Project is readily accessible by all-weather gravel roads and is near infrastructure, including hydro power transmission lines and gas pipelines. The nearby Canadian National Railway and major highways allow easy access to the port facilities at Prince Rupert, the closest major North American port to Asia.

The 2021 Wicheeda REE Project Preliminary Economic Assessment technical report ("PEA") outlined a robust after-tax net present value (NPV@8%) of $517 million and an 18% IRR[1]. This PEA contemplated an open pit mining operation with a 1.75:1 (waste:mill feed) strip ratio providing a 1.8 Mtpa ("million tonnes per year") mill throughput producing an average of 25,423 tonnes REO annually over a 16 year mine life. A Phase 1 initial pit strip ratio of 0.63:1 (waste:mill feed) would yield rapid access to higher grade surface mineralization in year 1 and payback of $440 million initial capital within 5 years.
