Yahoo Movies FRONTIER LITHIUM INTERSECTS 398.25M OF PEGMATITE AVERAGING 1.88% Li2O, INCLUDING A 23.4M ZONE OF 3.12% Li2O
SUDBURY, ON, Feb. 8, 2023 /CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX: LITOF) ("Frontier" or "the Company") is pleased to announce the results for the remaining seven drill holes completed during Phase XII drill program on the Spark pegmatite which began in May with two diamond drill rigs and finished in October of 2022.The main objective of the program was focused on converting inferred material to the indicated category for the planned open pit. The Spark pegmatite is one of the two delineated premium spodumene-bearing lithium deposits on the PAK Lithium Project.
Highlights
The Company completed 15,984m of drilling in 50 holes in 2022. Highlights from the seven Phase XII diamond drill holes reported are included below.
DDH PL-094-22 was designed to define the western extent of the Spark pegmatite and to target the recently discovered NW Spark zone. This hole was the first indication that the NW zone was connected to the main Spark pegmatite at depth, intersecting 125.9m of pegmatite averaging 1.51% Li2O.
DDH PL-098-22 hole was designed to follow up on the results from PL-094-22 and confirmed that the NW zone is in fact connected to the main Spark ore body at depth, intersecting 398.25m of pegmatite averaging 1.88% Li2O.
DDH PL-099-22 hole was designed to follow up on the results from PL-098-22, intersecting 243m of pegmatite averaging 1.58% Li2O, extending the NW zone further to the west.
"Now that all the results have been received and processed, we can say that our goal of upgrading Inferred has been achieved and the Spark pegmatite continues to increase in size particularly with the intersections in holes PL-098-22 and PL-099-22. These two holes, which are 140m apart, have confirmed that the new northwest zone discovered in February 2022 is connected to the main zone and contains significant high-grade zones of 2 to 3% Li2O." states Garth Drever, VP Exploration. "This zone will certainly be explored during the 2023 drill program at Spark."
The initial objective for the Phase XII drill program was focused on converting the inferred resource within the Spark deposit to the indicated category in preparation for a pre-feasibility study (PFS) on the PAK Lithium Project. The latter half of the program included geotechnical drilling for ground control and pit design purposes as well as step out drilling to define the eastern and western extents of the ore body.
Figure 1 is a location map showing the project area including Frontier's land tenure and location of the three lithium-cesium-tantalum pegmatites.
Figure 2 is a plan view showing all drilling with analytical data completed with emphasis on drill hole traces reported in this release.
