Frontier Lithium Releases Remaining Phase II Drilling Results of the Spark Pegmatite

Canada NewsWire

Highlights

  • Phase II diamond drill program includes four holes drilled totaling 1,159.5m; all intersecting significant zones of spodumene pegmatite; assay results have been received for all outstanding samples;
  • DDH PL-044-19 intersected 75m of pegmatite averaging 1.4% Li2O, including 19.0m of 3.4% Li2O;
  • DDH PL-045-19 intersected 144.2m of pegmatite averaging 1.4% Li2O;
  • An additional 52m of channeling was completed on surface averaging 1.5 to 1.77% Li2O;
  • 1,600m of intersected pegmatite in 9 drill holes from the first two phases of drilling and surface channel samples has resulted in an average grade of 1.53% Li2O.
  • Management initiates Maiden resource estimate on the Spark pegmatite.

SUDBURY, ON, Jan. 7, 2020 /CNW/ - Frontier Lithium Inc. (TSX.V: FL) (the "Company) is pleased to announce the remaining results of their second Phase of drilling on the Spark Pegmatite.  Frontier completed four diamond drill holes totaling 1,159.5 m in July-August 2019 (Table 1).  During the drill program an additional 4 channels totaling 52 m (Table 2) were cut and most of the exposed outcrop surface in the immediate area of the pegmatite was mapped. An analysis of the results from the drill program and assay results from the first two drill holes are included in a Press Release dated September 24th, 2019 and will not be repeated in this Press Release.

"Supported by preliminary modelling, we strongly believe in the potential for economic viability of the Spark pegmatite." commented Garth Drever, Vice President of Exploration. "The deposit remains open to the west and has maintained consistency in both grade and width with depth. The physical data collected through surface and remote mapping at PAK and Spark has proven invaluable as a first-pass exploration tool to evaluating the potential of our mining claims on the Electric Avenue."

Table 3 shows a summary of the assay results of holes PL-044-19 and PL-045-19.

Hole PL-044-19 was designed to step out 50m to 75m to test the extension of the pegmatite to the west of hole PL-039-19.  Three significant pegmatite zones were intersected with an upper 75m intercept averaging 1.4% Li2O.  The two lower zones of 12 and 27.4m consist of slightly lower grade spodumene-bearing aplite averaging 0.74% and 0.87% Li2O.

Figures 2 and 3 are Sections for holes PL-044-19 and PL-045-19 respectively showing Li2O content as histogram plots along the drill hole and channel traces.  The section in Figure 2 was extended to include hole PL-039-19.  Although only scattered remnants of pegmatite were noted on surface during mapping and prospecting it is apparent that there are two significant lobes of the pegmatite that extend upward to the surface beneath the overburden.

The final hole of the program, PL-045-19, extended hole PL-037-19 which had been abandon.  Hole PL-045-19 intersected a 17.1m zone of spodumene-bearing aplite averaging 0.78% Li2O before intersecting a 144.2m zone of predominately pegmatite from 70.8 to 215m averaging 1.4% Li2O.  A 15m zone from 130 to 145m averages 2.47% Li2O.  Anomalous Ta, Sn and Rb occurs over an 11.2m zone from 175 to 186.2m averaging 659 ppm Ta2O5, 520 ppm SnO2 and 0.88% Rb2O. An analogous zone of enriched Ta is present above in Channel 37 from 63.2 to 69.4m (6.2m) averaging 615 ppm Ta2O5 (see Press Release January 17, 2019).   Figure 3 shows the section of hole PL-045-19 with Channels 37 and 38 plotted at surface.  Both Li2O and Ta2O5 are plotted along the trace of the drill holes and channels.

During the summer drill program an additional 52m of channels (Channels 41 to 43) were cut to complete the section between Channel 38 and start of Channel 40 and to sample across the western most exposed lobe of the pegmatite (Channel 44).  These channels are highlighted on Figure 1 and displayed in Figure 4 in a section including hole PL-040-19 and PL-043-19.  Assay results are summarized in Table 4.  All channels were logged as spodumene-bearing Na-aplite with consistent grades between 1.5 and 1.77% Li2O.  The aplite is typically fine to medium grained, light grey to greenish grey locally with coarser zonations consisting of megacrystic feldspar, fine to coarse-grained light grey to white spodumene laths, grey quartz and variable amounts of muscovite.

During the summer drill program much of what was previously described as metavolcanics rock has been subdivided into metasedimentary units which are now recognized to be intercalated within the metavolcanics sequences. 

Due Diligence

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, all drilling was completed by Chenier Drilling Ltd. of Val Caron, ON using thin-walled BTW drill rods (4.2 cm 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 halve bagged for analysis.  Sample blanks along with lithium, rubidium and cesium certified reference material was 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 Frontier employees and then shipped to AGAT Laboratories Ltd. (AGAT) in Mississauga, ON for quantitative multi-element analysis.  AGAT is an ISO accredited laboratory. All petrographic sample preparation and electron microprobe (EMP) analysis was completed at the Queen's Facility for Isotope Research (QFIR) at Queen's University in Kingston, Ontario under the direct supervision of Dr. Steve Beyer. The core is stored on site at the Pakeagama Lake exploration camp.
