Frontier Lithium Intersects 231m of 1.61% Li2O During Phase II Drilling 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 the first 2 drill hole;
  • DDH PL-042-19 intersected a total of 231 m of pegmatite averaging 1.61% Li2O, including 25.0m of 2.75% Li2O;
  • DDH PL-043-19, to the west intersected three narrow (10 to 25m) dykes which is consistent with the surface expression of the pegmatite. Grades ranged from 1.0 to 1.5 % Li2O;
  • The deposit displays consistency in both composition and lithium grades across the width of the pegmatite down to at least 200m depth;
  • All indications suggest the Spark Pegmatite is vertically emplaced; open to the west with a multiple dyke-system extending to the east.

SUDBURY, ON, Sept. 24, 2019 /CNW/ - Frontier Lithium Inc. (TSX.V: FL) (the "Company) is pleased to announce the initial 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.  During the drill program an additional 4 channels totaling 52 m were cut and most of the exposed outcrop surface in the immediate area of the pegmatite was mapped. Geochemical results from the first two drill holes have been received.  The remaining analysis is expected by the end of October.

Figure 1 is a location map showing the surface outline of the Spark pegmatite, location of channels and drill hole traces with geology overlain on detailed imagery of the outcrop area. Phase I drilling in February focused on targeting the pegmatite from the south along the base of the 30 to 40 m high ridge of predominately pegmatite.  Three holes were drilled during Phase II from the top of the ridge back towards the Phase I collars and the fourth hole was a re-drill of hole PL-037-19 which had been abandoned. 

All holes intersected significant widths from 20 to 125 m of pegmatite. Spodumene grain size and abundance tends to increase with the presence of quartz and feldspar megacrysts which is similar to the LIZ (Lower Intermediate Zone) and locally similar to the CIZ (Central Intermediate Zone) of the PAK Pegmatite. The exposed pegmatite and host metavolcanic rock has been mapped over most of the immediate area (Figures 1).  Overburden stripping is required to the west and to the east in the area of Channels 39 and 40.

Figures 2 and 3 are sections for holes PL-042-19 and PL-043-19, respectively, showing Li2O content as histogram plots along the drill hole and channel traces.  The intersections of pegmatite as illustrated in Figure 2, are broad and contain minor metavolcanic host rock. During Phase I program DDH PL-038-19 intersected 215m of pegmatite averaging 1.4% Li2O, including 62.0m of 1.81% Li2O. (See Press Release dated April 9,2019) Surface observations and the drill intersections indicate there are two, possibly three main pegmatite zones/dykes that are 50 to 75m wide on the western margins with much narrower dykes to the east.

"We are extremely pleased with the drilling results and are confident that enough information is available to complete a resource estimate before year-end." commented Garth Drever, Vice President of Exploration. "We are currently compiling a 3-D model using the digital elevation model, surface mapping, channels and drill data. Due to the effectiveness of the drilling we believe there is adequate data to support a resource estimate with both Indicated and Measured categories included. The reality for an at-surface deposit to augment the PAK project resource size is genuine."

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. The core is stored on site at the Pakeagama Lake exploration camp. 

About Frontier Lithium

Frontier Lithium is a Canadian junior mining company with the largest land position in the Electric Avenue, an emerging premium lithium mineral district located in the Canadian Shield of northwestern Ontario. The company's PAK Lithium Deposit contains North America's highest concentration of rare low-iron spodumene. Frontier Lithium's objective is to firstly become a near term producer of premium technical grade lithium mineral concentrates of 2,000 tonnes of Lithium Carbonate Equivalent ("LCE") for glass producers. Through a phased approach to scale up to 20,000 tonnes by 2025 by ramping up production of concentrates and building a downstream processing facility to produce lithium chemicals required by glass and battery materials producers.

Frontier maintains a tight share structure with management ownership exceeding 30% of the Company.

About the PAK deposit

The PAK Deposit is located in the south end of Ontario's Electric Avenue, a newly emerging premium lithium-metal district. Electric Avenue also hosts Frontier's newest discovery, Spark showing (2km northwest) and the Pennock Lake pegmatite occurrence a further 30km along Frontier's PAK Lithium Project. The PAK deposit has a mineral resource estimate of 9.3 Mt averaging 2.04% Li2O which has a rare technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3) as per its NI 43-101 Technical Report, "Preliminary Feasibility Study" disseminated on April 16, 2018.
