District Metals has commenced diamond drilling at the Österkälen mineral licence in central Sweden, part of its 100%, owned Alum Shale Properties.
The programme is designed to test prospective Alum Shale mineralisation linked to overlapping geophysical and geochemical anomalies identified across the property.
The first holes will concentrate on a MobileMT conductive anomaly identified in 2025, which the company says coincides with geochemical soil anomalies interpreted as indicating favourable Alum Shale stratigraphy.
Alum Shale is a Cambrian–Ordovician black shale known to host uranium and associated critical metals such as vanadium, molybdenum, nickel and zinc, making Österkälen relevant to both energy and critical-mineral exploration.
During drilling, District Metals plans to use geological observations and uraniferous radiometric measurements collected from the core to guide how many holes are completed and the total metres drilled.
This real-time data will help determine whether the targeted conductor extends along strike or down-dip and whether the campaign should be expanded.
In addition to radiometric scanning, the company may log core for shale stratigraphy, collect multi-element geochemical samples and integrate results with geophysical modelling to refine future targets.
No fixed hole count or total metreage has been disclosed, giving District Metals flexibility to adjust the programme as initial results are received.
District Metals CEO Garrett Ainsworth said: “We are pleased to have commenced our first drill programme targeting Alum Shale mineralisation in Sweden. The large conductive MobileMT anomaly at Österkälen is interpreted to represent Alum Shale and has dimensions consistent with a district-scale target.
“By integrating geophysical, geochemical and geological datasets, we have identified a high-priority target that has never previously been drill tested. Read more...
