The final set of drilling results has been released for the second programme of drilling at the Bergby lithium project in Sweden, which is 100% owned by Leading Edge Materials Corp. Drilling intersected regular high lithium grades, and was notable for significantly increased tantalum grades in comparison to prior drill holes.
Highlights
- BBY17025 intersected 5.1 m @ 361ppm Ta2OM5 (tantalum oxide) from 25.1 m depth.
- BBY17026 intersected 2.8 m @ 297ppm Ta2OM5 from 49.2m depth.
- BBY17030 intersected 5.4 m @ 1.60% Li2O, 155ppm Ta2OM5 from 25 m depth.
- BBY17031 intersected 4.5 m @ 1.31% Li2O, 164ppm Ta2OM5 from 71.5 m depth.
- BBY17033 intersected 3 m @ 1.33% Li2O, from 52.8 m depth.
Holes BBY17025 to BBY17029 were drilled along the strike of the pegmatite to the north of previous drilling, up to 800 m from the discovery zone (hole BBY17029). Where pegmatite was intersected in this northern area, it was notable for a lower lithium grade and a significant increase in the tantalum grade, suggesting a different style of LCT pegmatite (lithium-cesium-tantalum) was intersected. Pegmatite was not intersected in holes BBY17027 to BBY17029, which may indicate a steeper dip than anticipated from nearby lithium mineralised outcrop.
Holes BBY1030 to BBY17033 tested down dip from prior drilling, and all except for BBY17032 intersected high grades of lithium mineralisation consistent with previous intersections. Mineralisation remains open in a down dip direction over at least 600m of strike.
Bergby has now been tested by a total of 1525 m of drilling in 33 drill holes to a maximum depth of 131.1 m over an approximate 1500 m strike length. The true thickness of mineralised intervals is interpreted to be approximately 90% of the sampled thickness.
President and CEO of Leading Edge Materials Corp, Blair Way, stated: “These final results from the second programme of drilling at Bergby have again delivered the strong encouragement of high lithium and tantalum grades over more than 1 km of strike. The grade variation is typical of LCT pegmatite fields, and has highlighted that there may be much more to find under the thin glacial soil cover. Bergby remains a new lithium discovery at a very shallow depth, and we are now preparing a sample for metallurgical testwork to further advance the project.”
