Vanadiumcorp Reports Measured And Indicated Mineral Resources Of 214.93 Million Tonnes Grading 24.6% Magnetite And 1.3% V2O5 In Magnetite Concentrate (Equivalent To 1.49 Billion Pounds Of Vanadium)
VanadiumCorp Resource Inc. (TSX VENTURE: “VRB”) (OTCBB:”APAFF”) (FRANKFURT:”NWN”) (the “Company”) is pleased to report the results of a Mineral Resource Estimate (MRE) for the Company’s 100% owned Lac Doré Vanadium Project. The total Measured and Indicated Mineral Resources for the Lac Doré project are estimated at 214.93 million tonnes (Mt) of mineralized material contained in the Lac Doré Main Zone with the potential to produce 52.97 million tonnes of magnetite concentrate grading 1.3% Vanadium Pentoxide (V2O5), 62% Iron (Fe) and 8.7% Titanium Dioxide (TiO2).
In addition, the Lac Doré project hosts 86.91 Mt grading 0.4% V2O5, 28.0% Fe, 7.6% TiO2 and 25.9% magnetite concentrate in the Inferred category which are estimated to contain 22.55 Mt of magnetite concentrate grading 1.2% V2O5, 62% Fe and 9.2% TiO2.
VanadiumCorp now has sufficient Mineral Resources in the appropriate categories to progress with a preliminary economic assessment or prefeasibility study. The Company plans to independently validate its green jointly owned VanadiumCorp Electrochem Process Technology (“VEPT”) for use in future economic studies.

The Lac Doré Vanadium Project is comprised of 115 mining claims (100% Company-owned) spanning an area of 45 km2 located 27 km southeast from the mining city of Chibougamau, in Eeyou Istchee James Bay Territory, Northern Québec. The Chibougamau area is host to several vanadiferous vanadium bearing titanomagnetite (VTM) deposits, including the adjacent Southwest and Armitage deposits owned by BlackRock Metals Inc. and the Mont Sorcier deposits owned by Vanadium One Iron Corp. which are located on the north rim of the Lac Doré Complex.
Vanadium at the Lac Doré Vanadium Project is hosted in layered zones of VTM that crop out at surface and dip at approximately 60° to the southeast. The Lac Doré MRE was completed and reported by CSA Global in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards. The MRE includes recent infill drilling conducted at the Lac Doré Vanadium Project successfully completed on October 15th, 2019 (Click here for News Release) by independent mining industry consultants, InnovExplo Inc. Detailed sampling (generally at 1.5 m or less) of the various magnetite-bearing stratigraphic units in the layered portion of the Lac Doré Complex allowed the delineation of magnetite layers with higher vanadium grades.
Grades and tonnages are reported for both the head grade of total mineralized material as in-situ rock containing VTM and other minerals, as well as for the magnetite concentrates (i.e. for material where VTM has been concentrated by magnetic separation, as estimated using Davis Tube testing and previously reported by the Company). Results are summarised in Table 1.
Adriaan Bakker, President and CEO of VanadiumCorp, states: “The results of the Mineral Resource estimate for our Lac Doré Vanadium project have exceeded our expectations. We can state Lac Doré is one of the largest undeveloped deposits of vanadiferous magnetite in the world, with an excess of 1.4 billion Lbs of vanadium pentoxide contained in magnetite concentrate. The favorable metallurgy/Davis Tube results demonstrate the potential of the Lac Doré deposit to yield magnetite concentrates with high vanadium grades, with a significant proportion of the resources exceeding 1.4% V2O5 in magnetite concentrate. The significant tonnage of the Measured and Indicated mineral resources highlights the excellent continuity of the VTM mineralization at Lac Doré and sets the stage for more advanced technical studies on the project, including metallurgical testing.”
Numbers have been rounded and may not sum exactly.
Mineral Resources are estimated and reported in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves adopted May 10, 2014.
Geological and block models used data from 41 drill holes drilled by the Company in 2013 and 2019, in addition to 44 drill holes and 33 surface channel samples completed previously and verified through twinning or resampling in 2019/2020.
The drill database was validated prior to estimation, and drill holes were flagged with interpolation domains (P1, P2-LOW, P2-A, P2-PART, P2-B, P2-HW, P3), composited to 1.5m intervals, and capped for anomalously high and low-grade values. QAQC checks included insertion of blanks, certified reference materials pulp duplicates and umpire assays performed at a second laboratory.
Head grades and densities were interpolated onto 10mx10mx10m blocks using ordinary kriging (OK), Owing to intercalations of high and low magnetite within broadly mineralized intervals, a high-grade or low-grade indicator was used, and separate interpolations carried out for high-grade or low-grade samples, with the proportion of high-grade mineralization within each block also interpolated using OK.
All the estimates were validated visually using sections and 3D visualization, and using swath plots, comparison of averages in drill hole and blocks, and global change of support.
Magnetite contents and concentrate grades were calculated using regression formulae deduced from Davis Tube results.
Resource classification was done using wireframes digitized using kriging variance as a reference and correspond to Measured Resources having drill holes spacing 100 m.
Mineral Resources are reported using a “Net Value” cut-off, calculated assuming an open-pit mining operation and extraction of saleable vanadium pentoxide flake from the magnetite concentrate via the salt-roast process. The calculation assumes a V2O5 price of USD 7/lb, 85% recovery of magnetite to the concentrate, 75% recovery of vanadium in the roast/leach extraction process, and costs of USD 3/t RoM (mining), USD 15/t conc (magnetite conc production), USD 55/t conc (roast/leach), USD 2/t RoM (G&A) and USD 1.5/t RoM (tailings disposal). A net-value equal to zero was used for reporting.
Mineral Resources are constrained by a pit shell optimized with the software SimSched using the above parameters and including a cost of USD 3/t for waste rock extraction and assuming maximum pit slope angles of 45°.
Dr. Adrian Martinez, P.Geo (ON), OGQ Special Authorization, CSA Global Senior Resource Geologist, is the independent Qualified Person with respect to the MRE.
Recoveries of V2O5, Fe2O3 and TiO2 to the magnetite concentrate are variable.
Mineral Resources are constrained by claim boundaries.
The Company is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing or political factors that might materially affect these Mineral Resource estimates.
These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured, however, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
The Lac Doré project is a magmatic VTM deposit found in the upper portions of the Lac Doré Complex, thought to have formed through primary magmatic processes. It comprises multiple layers of disseminated to massive VTM mineralization that are laterally continuous and form a magmatic stratigraphy, and which dip at approximately 60° to the SE. These layers can be traced along strike over at least 3 km, and the deposit was previously subdivided into several zones, namely P0, P1, P2 and P3 (from stratigraphically lowermost to uppermost). The magmatic stratigraphy of the deposit has more recently been divided into a more detailed series of mineralized zones (P1, P2-LOW, P2-A, P2-PART, P2-B, P2-HW, P3). Each of these zones has distinct magnetite characteristics primarily related to the magnetite content and the grade of vanadium and titanium contained in the magnetite, and the MRE has characterized each of these zones individually.
Magnetite concentrate refers to the quantity and quality of iron-rich magnetite that has been separated from the in-situ material via magnetic separation following crushing and grinding of the in-situ material. For the purposes of evaluation/testing of magnetite deposits, this separation is done using Davis Tube Recovery (DTR). DTR testing generates the weight recovery/magnetic iron, or proportion of the deposit which is magnetite, and the grade of magnetite concentrate at a given grind size. This recovered magnetite concentrate is assayed for several elements, including vanadium, iron, and titanium.
