Frontier Lithium Inc. announced update on the winter work program with results from five geotechnical holes drilled on the Spark pegmatite to advance the first phase of definitive feasibility study. Highlights: DDH PL-GDH-24-24 intersected 136.7m of pegmatite from surface averaging 1.32% Li2O. DDH PL-GDH-26-24 intersected 53.2m of pegmatite from surface averaging 1.24% Li2O and 26.9m from 222.0 to 248.8m averaging 2.12% Li2O and 0.7% Rb2O.

Including 8.4m from 45.1 to 53.5m averaging 2.33% Li2O Including 5.0m from 116.8 to 121.8m of promoted Ta (685 ppm Ta2O5) and Sn (1,465 ppm SnO2). Including 7.0 m from 240.8 to 247.9 averaging 2.97% Li2O and 1.04% Rb2O DDH PL-GDH-27-24 intersected 48.1m of pegmatite from surface averaging 1.93% Li2O and another 49.8m from 129.7 to 179.5m averaging 2.23% Li2O with promoted Cs (0.61% Cs2O) and Ta (461 ppm Ta2O5) Including 8.3m from 31.7 to 40.0m averaging 3.33% Li2O Including 5.9m from 144.1 to 150.0m of 3.4% Li2O and 2.75% Cs2O DDH PL-134-24 stepped out 200m to the west as a condemnation hole, intersected 26.8 m of pegmatite from 18.9 to 45.7m confirming that the Spark pegmatite remains open. During the winter season, four geotechnical holes (PL-GDH-24 to 27-24) were drilled from the top of Spark in four directions to test pit-wall stability and hydrogeological conditions.

As expected, mineralized pegmatite was intersected in all holes. A fifth condemnation hole was drilled 200m to the west, near a proposed overburden stockpile. In addition to the diamond drilling at Spark, during February-March geotechnical drilling continued on potential infrastructure sites including stockpiles, tailing management, mill and other related facilities.

Environmental studies and monitoring continued and well as community engagement.
