High-Grade Lithium Oxides At Spodumene-Bearing Pennock Pegmatite

SUDBURY - Frontier Lithium Inc. on the regional prospecting and channel sampling program at Pennock, located 22 km northwest of the Spark Deposit. The spodumene-bearing Pennock Pegmatite is a 1.5 km long pegmatitic dyke trend that was first channeled in 2019 with 16m averaging 1.96% Li2O. Channel 56: 700m east southeast of the main blowout along the Pennock dyke system, crossed 3.0m of pegmatite averaging 1.8% Li2O. Channel 55: 55m to the east of Channel 56, crossed 5.8m averaging 1.0% Li2O.

"This was our first opportunity to validate the spodumene-bearing Pennock dyke beyond the "blowout" area with continuous channeling across the dykes. They tend to be extensive, continuous and contain high grades of lithium oxide" says Garth Drever, VP Exploration of the Company. "Despite being narrow at surface with widths less than 6 metres and requiring additional channeling and mapping prior to any drill testing, we are excited about the potential discovery upside outside of the project's mining lease area."

As part of the 2023 summer drill program at PAK, exploration crews were mobilized to the Pennock area for follow-up to the 2022 mapping and prospecting to complete sampling along 3 channel cuts. This resulted in the discovery of several additional pegmatite/aplite dykes, many of which were channeled. The pegmatite dykes near Channels 55 and 56 had been chip sampled in the past when spodumene had been identified. The channeling has now confirmed the presence of both spodumene and high grades of lithium oxide. Although spodumene was not visibly identified in the lepidolite-bearing aplite at Channel 54, it was channeled to determine the Li2O content and for further study.
