The exploration program at the Lac Doré Vanadium property has been designed by the Company with the aid of mining industry consultants CSA Global of Vancouver and InnovExplo of Val-d'Or, Québec. The drill program is being managed by InnovExplo, under the supervision of the Table jamésienne de Concertation Minière of Chibougamau, Québec. The drilling is being carried out by Miikan Drilling Ltd. of Chibougamau. InnovExplo is also in charge of core logging and core sampling which are being carried out in Chibougamau. All core samples will be sent for assaying and for selective Davis Tube testing to SGS Canada Laboratories in Val-d'Or, Québec an independent ISO 90001:2015 accredited laboratory facility. The results of the drilling program will be disclosed once received and validated by the Qualified Person. Details of the metallurgical test work program will be finalized following the assessment of the drilling results.
Strict QA/QC protocols designed by InnovExplo and CSA Global will be implemented to ensure the assay results are relevant, reliable and in accordance with industry standards, CIM Mineral Exploration Best Practice Guidelines (CIM Exploration Guidelines, 2018) and National Instrument 43-101 – Standards of Disclosure for Mineral Projects (NI 43-101) disclosure requirements. All new and historical drill hole collars will be surveyed by a professional surveyor at the end of the drill program. A Lidar survey will be performed during the fall to obtain a high-resolution 3D image of the property's topography.
The QAQC Protocol is as follows:
Minimum 5% appropriate VTM standards to be inserted into the sample stream (i.e. 1 standard per 20 samples);Minimum 5% blanks to be inserted into the sample stream;All coarse rejects and pulps to be collected from the laboratory5% of pulps to be resubmitted to SGS in later batches as duplicates with new sample numbers5% of pulps to be submitted to an umpire laboratoryAnalysis and Validation of Historical Drill and Outcrop Channel Sampling Data
With the objective of preparing the dataset for a future Mineral Resource Estimate, additional validation and verification of historic data will be carried out over the next weeks as part of the current program in order to ensure that the project data is in accordance with CIM Exploration Guidelines (2018), CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards, 2014) and NI 43-101 disclosure requirements. This work will include the resampling of channel samples in historical trenches, the surveying of historical drill holes collars where they can be located, along with the resampling of select core from historical drill holes still available. The same assaying and QA/QC protocols used in the current drilling will be used for the re-assaying of historical holes and outcrop channels.
Metallurgical Testing
Following logging and sampling of the drill core, VTM mineralized intersections will be tested using a combination of major and trace element assays, size-grading analysis, Davis Tube testing and other magnetic tests to assess the head grades and concentrate grades for vanadium, titanium and iron, as well as magnetite content and magnetite proportions relative to ilmenite. More details on this program will be presented when the analytical results are received and disclosed.
Note on Historical Vanadium Grades in Magnetite
The identification of magnetite concentrates with grades >1.7% V2O5 in several historic drill holes (Table 1 and Table 2) suggests the potential for elevated vanadium grades in magnetite from the P1 unit or the lower parts of the P2 unit, both of which contain moderate magnetite contents (15-40% magnetite). In typical layered magmatic magnetite deposits, stratigraphically lower units contain higher concentrations of vanadium in magnetite, with the vanadium content in magnetite decreasing and titanium content moving upward in the stratigraphy. This pattern is seen in results from previous drilling. The samples with elevated V2O5 contents generally do not contain magnetite concentrations as rich as the massive accumulations found in the upper part of the P2 and in the P3 units and have therefore not been the focus of previous exploration efforts on the property. However, the identification of areas with elevated concentrations of vanadium in magnetite could potentially prove important for future processing options and project economics. |
