The Inferred category is defined with a minimum of two (2) drill holes within the areas where the drill spacing is less than 120 m and shows reasonable geological and grade continuity. The Indicated mineral resource category is defined with a minimum of three (3) drill holes within the areas where the drill spacing is less than 60 m and shows reasonable geological and grade continuity. The mineral resource estimate is classified as indicated and inferred. Bulk density values applied are 3.13 and 2.91 for the olivine ferrosyenite and pyroxene ferrosyenite, respectively the principal hosts for the mineral resources.Ĩ. Grade interpolation was obtained by inverse distance squared using hard boundaries.ħ. The resource estimate was completed using GEOVIA Surpac 2021 using a sub-block model at a parent block matrix of 5m x 5m x 5m (minimum block size of 1.25m x 1.25m x1.25m). No capping was applied to Sc 2O 3 and Tb 4O 7.Ħ. High-grade capping supported by statistical analysis was done on raw assay data before compositing and established for La 2O 3 (3690 g/t), Pr 2O 3 (1380 g/t), Nd 2O 3 (2100 g/t), Dy 2O 3 (215 g/t). The estimate encompasses three mineralized zones using the grade of the adjacent material when assayed or a value of zero when not assayed.ĥ.
The results are presented in-situ and undiluted and considered to have reasonable prospects of economic viability.Ĥ.
Mineral Resources are classified in accordance with the CIM (2014) Standards and Definitions of Mineral Resources.ģ. These mineral resources are not mineral reserves, as they do not have demonstrated economic viability. The effective date of the estimate is September 17, 2021.Ģ. (Associate Resource Geologist, InnovExplo) and Carl Pelletier, P.Geo. (Resource Geologist, InnovExplo), Paul Daigle, P.Geo. The independent and qualified persons for the mineral resource estimate, as defined by NI 43 101, are Marina Iund, P.Geo. With these highly favourable results in hand, we will soon commence work on an NI 43-101 Preliminary Economic Assessment (PEA) for the project.”ġ. “Particularly important was that, due to our very tight drill pattern this past winter, our Independent QPs determined that a significant percentage of the defined resources was classified as Indicated category. “We are extremely pleased by the results of the Resource Estimate for the Northern Lobe of the TG, which far exceeded the minimum threshold resource we internally set for a 20-25-year notional mining operation, or 10 million tonnes,” said Peter Cashin, Imperial’s President & Chief Executive Officer.

The full report will be released and filed within the next 45 days. The effective date of the Mineral Resource Estimate is September 17, 2021.
The work was completed by InnovExplo Inc. ("Imperial") ( TSX VENTURE: IPG OTCQB: IMPNF) is pleased to announce that it has received the results of the inaugural 43-101 Mineral Resource Estimate for the TG Scandium-Rare-Earth Zone. 23, 2021 (GLOBE NEWSWIRE) - Imperial Mining Group Ltd. Mineralization remains open laterally and at depth, demonstrating the potential to increase the mineral resource with additional drilling. The dimensions of the zone above the NSR cut-off were 300 m in strike length to a vertical depth of 200 m. Using a Net Smelter Return (NSR) cut-off value of $CAN110.80/t, the value of the mineralization was determined to range between $CAN386-413/t. Imperial’s independent qualified persons report Indicated Resources of 7.3 million tonnes grading 282 g/t Sc 2 O 3 and Inferred Resources of 13.2 million tonnes grading 262 g/t Sc 2 O 3 for the Northern Lobe of the TG Scandium Zone.ĭeterminations of magnet rare earth oxides (Nd, Pr, Dy, Tb) were made for both resource categories.
