Frontier Lithium drills 109.5 m of 0.96% Li2O at PAK

2023-08-10 08:26 ET - News Release

Mr. Garth Drever reports


Frontier Lithium Inc. has released drilling results on four additional holes drilled on the Bolt pegmatite. Until this year, the Bolt pegmatite had only been mapped and channelled on surface exposures, and it is located between the Spark and PAK spodumene-bearing lithium deposits on the PAK lithium project. Several condemnation holes were also drilled in preparation for an upcoming definitive feasibility study on the PAK lithium project.


  • The company completed 3,806 metres in 15 drill holes delineating Bolt.
  • Diamond drill holes PL-111-23 and PL-112-23 indicate that the Bolt pegmatite has a horizontal width of up to 75 m wide.
  • DDH PL-111-23 intersected 109.5 m of pegmatite averaging 0.96 per cent lithium oxide:
    • Including 29.0 m from 148.0 m to 177.0 m averaging 1.14 per cent Li2O;
    • Including 34.2 m from 192.0 m to 1,226.2 m averaging 1.17 per cent Li2O.
  • DDH PL-112-23 intersected 90.1 m of pegmatite averaging 0.72 per cent Li2O:
    • Including 26.6 m from 176.3 m to 202.9 m averaging 1.51 per cent Li2O.

"The latest results suggest that the Bolt pegmatite is wider than what we initially suspected," stated Garth Drever, vice-president of exploration. "Bolt appears to have a large central zone that breaks up along strike into a series of dikes of variable thickness."

Surficial detailed mapping at Bolt is currently under way and includes channel sampling. Access in the area is hindered by underbush and deciduous regrowth in the overburden regions of the pegmatite and mafic exposures. Initial results are encouraging, extending the surficial pegmatite outcroppings southwest above drill hole intersections.

As previously reported, there may be continuity between the Bolt pegmatite and the Spark deposit located 200 m to the northwest, but that continuity is undetermined and will require additional drilling. Bolt mineralization currently extends to within 100 m of the Spark pit shell. The pegmatite appears to be cut off along strike to the southeast but remains open at depth. Pegmatitic intersections in PL-111-23 and PL-112-23 with horizontal widths of 75 m and 60 m, respectively, are encouraging and correspond to the recent surficial mapping.

A series of widely spaced single condemnation holes were drilled mainly in areas of planned infrastructure, including the region between PAK and Bolt, to confirm the absence of mineralized pegmatites near surface.

The drill program encompassed three drill holes at Spark, drilled in late March and concluded in July, with a fourth drill hole spanning 550 metres. The primary focus of these endeavours was to explore the western extension of the Spark pegmatite. Spodumene-bearing pegmatite was intersected in all holes. The phase 13 drilling is now complete for the year, with assay results continuing to come in.

An attached table details the drill holes with mineralized intersections at Bolt.

Due diligence

All scientific and technical information in this release has been reviewed and approved by Garth Drever, PGeo, the qualified person under the definitions established by National Instrument 43-101. Under Frontier's quality assurance/quality control procedures, all drilling was completed by Chenier Drilling Ltd. of Val Caron, Ont., using thin-walled BTW drill rods (4.2-centimetre core diameter) and a Reflex ACT III-oriented core system. Using the Reflex system, the drill core was oriented and marked as it was retrieved at the drill. The core was boxed and delivered to the Frontier core shack, where it was examined, geologically logged and marked for sampling. The core was photographed prior to sampling. Using a rock saw, the marked sample intervals were halved, with one-half bagged for analysis. Sample blanks, along with lithium, rubidium and cesium certified reference material, were routinely inserted into the sample stream in accordance with industry recommended practices. Field duplicate samples were also taken in accordance with industry recommended practices. The samples were placed in poly sample bags and transported to Red Lake by float plane and then shipped to AGAT Laboratories Ltd. in Thunder Bay for sample preparation and to Mississauga, Ont., for processing and quantitative multielement analysis. AGAT is an ISO-accredited laboratory. The core is stored on site at the Pakeagama Lake exploration camp.
