High-Grade Intersections Complete Winter Drill Program and Exploration Commences

Hard-rock lithium explorer and developer Winsome Resources Limited (ASX: WR1; “Winsome” or “the Company”) is pleased to announce the final results for the 2022 winter drill program have been received and add significant areas of high-grade lithium mineralisation to the known ore body at the Company’s Cancet project in Quebec, Canada.

Highlights

• Final drill holes from winter drilling campaign show high-grade lithium intersections
• Pegmatite strike length of main ore body extended to 1200m
• Amongst other shallow high-grade intersections, WC-22-01 recorded 25.98m@ 1.55% Li₂O from 5.72m including intersections of:
  • 11.28m @ 2.45% Li₂O from 5.72m
  • 4.00m @ 3.89% Li₂O (8m to 12m)
• Field exploration work underway at Cancet at Adina and Decelles
  
• Significant tantalum mineralisation continues to be intersected

Of the seven drill holes for which final results have been received, two intersected high-grade zones of mineralisation. The other five targets, although showing promise from earlier magnetic surveying, did not intersect any significant lithium mineralisation and have been closed out.

The confirmation of these high-grade results and the increased knowledge gained by investigating nearby target zones now provides clear direction for the Company to continue its resource development and exploration activities at Cancet.

Winsome Managing Director Chris Evans said: “These high-grade results prove Cancet contains world class levels of lithium mineralisation close to surface. The latest findings give us further confidence to continue the resource development and exploration work across the significant landholding the Company has at Cancet. We remain focused on declaring a maiden resource in the near term.”

Key Results

• WC-22-01 – 25.98m @ 1.55% Li₂O from 5.72m depth, including:
  • 11.28m @ 2.45% Li₂O from 5.72m
  • 4.00m @ 3.89% Li₂O (8.0m to 12.0m)
• WC-22-18 – 12.00m @ 1.16% Li₂O from 3.0m depth, including:
  
  • 6.0m @ 1.55% Li₂O (3.0m to 9.0m)

These holes were planned to further understand the lithology of the main mineralised zones and were not specifically twinned to any previous drill holes.

Summary of Cancet Drilling

The Cancet project has now been subject to a significant amount of diamond drilling which has delineated a well mineralised, high-grade and shallow ore body. The most recent drilling campaign has built on the knowledge of the ore body gained in previous campaigns and will contribute heavily to the target of publishing a maiden resource at Cancet in the near term. A summary of significant drill results from the previous two drilling campaigns is listed below.

After the recently completed drilling campaign, the pegmatite field hosting the Cancet Ore body has been expanded from 600m strike length to 1200m strike length, and is characterised by mineralised zonation, with high-grade zones predominantly to the east (in orange) and lower grade zones to the west (in grey), as shown in figure 1 below.
