SPARK PROJECT
A New Discovery “the Spark”
On November 7, 2018, the Corporation announced the discovery of the Spark pegmatite intruding vertically into metavolcanics and metasedimentary host rocks. The pegmatite is located 2.3 km north-west of the PAK deposit. As a result of the Spark discovery, the Corporation increased their land position on the Electric Avenue by staking an additional 891 claim cells totalling 17,766 ha over a 65 km strike length.
Channel sampling was initiated at the time of discovery in September 2018 and completed a month later in October. The pegmatite is well exposed where minimal stripping by hand was required to complete the channel sampling. In total 236.4m of channels were cut representing two main transects. Results proved consistent lithium

grades and homogeneity across the width of the exposed pegmatite as highlighted by one transect of 94.5m averaging 1.85% Li2O.

The Corporation followed up in February 2019 with a 1,340 metre, 5-hole diamond drill program. Four of the holes were drilled from the south with one hole drilled from the north. All holes intersected significant widths of 20 to 74m of pegmatite averaging 1.2 to 1.92% Li2O. All indications suggest that the Spark pegmatite intruded vertically, cross cutting in an east-west direction, the main trend of the Bearhead fault zone and appears characteristically similar to the LIZ (Lower Intermediate Zone) of the PAK pegmatite.
A second phase of drilling consisting of 4 drill holes, three of which were drilled from the
north, totalling 1,160m and an additional 52m of channeling was completed in July 2019. The initial hole intersected a total of 231m of pegmatite averaging 1.6% Li2O. All indications suggest the Spark Pegmatite is vertically emplaced; open to the west with a multiple dyke-system extending to the east. The summer drilling completed the transects required for the resource estimate announced by WSP (February 4, 2020). The resource

estimate for Spark of 3.2 MT Indicated and 12.23 MT Inferred averaging 1.59% and 1.36% Li2O respectively, has more than doubled the overall lithium resource for the project.

The Corporation is currently performing a geostatistical analysis and metallurgical testing on representative samples from the Spark discovery. The primary objective from management is to assess material from the deposit and its metallurgical properties so that representative concentrates can be produced. This type of information is key to building a sustainable plan for a potential future Commercial scale mining operation on the Project.
Management believes that the Spark discovery combined with the PAK deposit is now considered “World-Class” and the size of resource would allow for Frontier’s objective of being a future fully integrated mining and chemical company producing 25,000 tonnes LCE for an estimated 15 or more years.
