Frontier discovers a new spodumene-bearing pegmatite “Bolt” between the PAK and Spark deposits.
Sudbury, Ontario, November 17, 2020 – Frontier Lithium Inc. (TSX.V: FL) (the “Company”) is pleased to announce that it has uncovered a significant pegmatite zone along trend of the Spark and PAK pegmatites. It has been traced intermittently over 600 m immediately to the west of Lucky Lake (Figure 1). A 36.4 m portion of the pegmatite was channeled returning 1.5% Li2O over the entire length (Table 1). Similarly, to PAK, it has been intruded concordant with the main trend of the host rock.
- The pegmatite has been traced for over 600 m with zones up to 50 m wide.
- It is concordant with host rock and appears to be vertically emplaced.
- Initial channel sampling has resulted in 1.5% Li2O over 36.4 m.
- The pegmatite has been aptly named “Bolt.”

While attempting to gain access on foot to the Spark pegmatite from the exploration camp at Pakeagama Lake several zones of pegmatite were discovered ranging between a few metres to over 50 m wide and traced for at least 600 m along the western side of Lucky Lake. The pegmatite encountered is generally concordant with the mafic meta-volcanic host rock and oriented sub-vertical. The surface of the pegmatite is typically dark grey, lichen-covered and oxidized making it considerably less conspicuous than the lighter-colored Spark and PAK pegmatites.
An easily accessible area towards to southern margin of the main exposure was channeled with two off-set channels oriented perpendicular to the main trend of the pegmatite. A mixed zone of pegmatite and metavolcanics (contact zone) occurs near and parallels the shoreline. Fine to medium grained, light grey to pale greenish grey aplite is present throughout the channeled pegmatite with coarse-grained grey feldspar phenocrysts up to 5 cm occurring locally with lesser amounts of muscovite and black tourmaline. Spodumene crystals, typically less than 3 mm and up to 8 mm, occur ubiquitously throughout the channeling. The composition and textures are similar to the Spark pegmatite.
“This new discovery emphasizes the need for meticulous and methodical mapping and prospecting in the vicinity of the PAK and Spark deposits.” states Garth Drever, VP of Exploration, “The fact that these exposed occurrences have remained undetected until now is a testament to just how prolific the “Electric Avenue” could be.”
All scientific and technical information in this release has been reviewed and approved by Garth Drever, P.Geo., the qualified person (QP) under the definitions established by National Instrument 43-101. Under Frontier’s QA/QC procedures, channels are cut with a motorized circular diamond saw, and are 4 cm wide and 10 cm deep. The channels are typically oriented perpendicular to the strike of the pegmatite internal mineralogical zones and are cut continuously across the zones. The samples are removed using a hammer and chisel.Samples are described, placed into a poly sample bag with a numbered sample tag and then shipped to AGAT laboratories in Thunder Bay for multi-element analysis. Detailed mapping and prospecting will be completed next summer to better define the extent of the pegmatite.
