Imperial Mining Crater Lake Drilling Returns Wide Scandium and Rare Earth Intersections: Driving to Deliver 43-101 Resource Estimate by June

 

 

 

 

 

Highlights:

  • Assay results from the first four drillhole continue to return impressive intercepts of 111.9 m (367.0’) grading 298 g/t scandium oxide (Sc2O3), including 40.5 m (132.8’) grading 336 g/t Sc2O3 and 34.77 m (114.0′) grading 321 g/t Sc2O3.
  • Elevated levels of total rare earth oxides plus yttrium (TREO+Y) of up to 0.38 % characterize the scandium-bearing horizon.
  • At current prices for the magnet rare earths (Nd, Pr, Dy, Tb) the rare earth mineralization will provide the project with important bulk concentrate value for the potential operation.

 

Imperial Mining Group Ltd. (TSX-V: IPG) (OTCQB: IMPNF) is pleased to announce that it continues to receive strong scandium and rare earth assays from Crater Lake drilling the TG scandium mineralized Zone. Assay results continue to return substantial intersection widths of scandium-bearing olivine ferrosyenite (Table 1) reported earlier (see Imperial press release – April 28, 2021). The drilling program was completed on May 9th, with a total of 14 drillholes having tested the Zone. Sufficient drill data has now been collected to undertake a 43-101 preliminary Resource Estimate of the TG zone for delivery in June.

 

“The winter drilling results at the Crater Lake property continue to build an important scandium and TREO+Y resource at the TGZ target,” said Peter Cashin, Imperial’s President & Chief Executive Officer. “Drilling has now defined the Zone on 50 m sections between  Sections 350N and 650N and mineralization has been traced by drilling over 650 m in total strike length down to a vertical depth of up to 200 m. Importantly, the zone is getting thicker and higher grade with depth and to the north of Section 500N.”

 

CURRENT DRILLING

 

To date, 14 drillholes for 2,084.8 m have been completed (Table 2, Figures 1, 2 and 3). All drillholes have intersected the target mafic intrusive host rock. The drilling indicates that the TG scandium zone is doubly dipping between 830 west to 700 east, with a north-northeast strike direction. The widths of the mineralized zone vary between 55 and 135 m (180-443’) in true thickness. Mineralization is open at depth below the 200 m vertical level and along strike and appears as a thickening, conical-shaped body in cross-section.

NOTES: – 1 ppm of Sc metal equals 1.5338 ppm scandium oxide (Sc2O3) ; 1 g/t equals 1 ppm. TREO+Y includes oxides of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu plus Y.

 

SECTION 350N DRILLING

     
CL21050 The hole intersected a cumulative thickness of 55.6 m of Sc-bearing mafic Olivine Ferrosyenite  (OLFESYN) intrusive with individual intersections of up to 20.0 m in core length.
     
 

SECTION 600N DRILLING

     
CL21052 This hole intersected a cumulative 154.9 m (508.1’) of Sc-bearing OLFESYN commencing at 56.5 m in the hole. The azimuth of this hole was reversed from the other holes on Section to confirm our initial inverted cone geometry of the zone. The largest intersection returned 142.5 m (467.4’) of OLFESYN, starting at 56.5 m in the hole. Of interest was 6.7 m thick interval of pegmatite containing very coarse amphibole aggregates with several inclusions of zircon and up to 10% of fluorite at the contact between the OLFESYN and the footwall felsic syenite. The high fluorite commonly carries high rare earth grades elsewhere on the property.
     
 

SECTION 650N DRILLING

     
CL21051 The hole intersected a cumulative thickness of 54.2 m (177.8’) interval of favourable OLFESYN starting at 73.5 m in the hole.
     
CL21053 The hole was a shallow overcut to hole CL21051 and intersected a cumulative interval of 19.3 m (63.3’) interval of favourable OLFESYN commencing at 22.2 m in the hole.

 

The mineralization on this Section has further confirmed that the system is building with depth and that the mineralization has a steep northern plunge geometry.

 

The core samples from holes CL21046 and CL21049 to CL21053 have been sent out for analyses and have been delivered to Activation Laboratories late last week. Results are anticipated to be delivered within three weeks of receipt of this remaining shipment.

QA-QC Protocol

 

Strict QA/QC protocols have been implemented for the Crater Lake Project, including the insertion of certified reference materials (standards), duplicates and blanks at regular intervals throughout the sequence of samples.

 

A total of 611 samples, including 36 QA-QC samples, were sent to an analytical laboratory. All sample preparation and analytical work was carried out by Actlabs at their facilities in Ancaster, Ontario. Several analytical techniques were used to characterize the samples, which are combined at Actlabs into the analytical package “8-REE”. This package includes whole-rock and trace element analytic techniques. Whole Rock analyses are done via a lithium metaborate/tetraborate fusion inductively coupled plasma (ICP) finish. Trace elements are also analyzed by fusion ICP/MS.

 

The technical content in this press release was prepared, reviewed and certified by Pierre Guay, P. Geo., Imperial’s Vice-President, Exploration, a Geologist and Qualified Person as defined by NI43-101.
