Burley Minerals (ASX: BUR) has received positive new assay data from drilling at its 100%-held Chubb Lithium Project, located 25km from the Val d’Or mining hub. Quebec, Canada.
Drill logs and core photos had provisionally identified intersections of spodumene in recently discovered pegmatite dykes to the East and West of Chubb’s Main Dyke, which now are interpreted as members of a parallel ‘stacked dyke’ system.
Spodumene being pegmatite was intersected in holes CLP-057 and CLP-058, the newly identified Eastern Dyke. Hole CLP-065 intersected 6.1m at 1.2% Li20 and 6.1m at 1.0% Li20, in the southernmost hole in Western Dyke, suggesting that spodumene mineralisation is broadening and is still open.
Holes CLP-063 and CLP-066, the southernmost holes in the Main Dyke, intersected 2.6m at 1.2% Li20 and 11 m at 1.7% Li20, confirming that spodumene mineralisation exceeds a strike length of 600 m, and is still open at depth.
Furthermore, assay results from hole CLP-063 returned caesium values of 2.4% over 4m. This confirms the initial identification of pollucite by a company geologist, and subsequent mineral mapping using LIBS scanning technology. Pollucite mineralisation has now been intersected in two holes, CLP-038 and CLP-063, which are more than 60 m apart.
“We are thrilled to discover additional spodumene-bearing pegmatite dykes within the Chubb Central Mineralised Zone. As our exploration program advances, more mineralised dykes have been identified and the extent of mineralisation has grown materially since drilling commenced in April 2023,” Managing Director and CEO, Stewart McCallion, said.
“We are also very pleased that the assay results from CLP-063 have confirmed the presence of the caesium bearing mineral pollucite in the Main Dyke, indicating an extremely evolved LCT pegmatite system, and which has the potential to add significant value to the Project.”
The company has completed approximately 13,000 m of drilling at the Chubb Project since April of 2023.
