Barsele Minerals Corp. provided an operational update regarding 2021 exploration activities within the Barsele Gold-VMS Project area in Västerbottens Län, Northern Sweden A mineralized boulder trail discovered in 2016 and lying to the southeast of the trend of the Avan-Central-Skiråsen zones was followed up by additional work, including Meffa soil sampling and boulder prospecting in late 2021. Another high-grade boulder of 90.8 g/t Au was found about 150 meters up-ice to the northwest of previous boulder discoveries.

This new boulder is over one meter in diameter and is subrounded to rounded and composed of quartz-sulphide (mainly pyrrhotite with some arsenopyrite) breccia in fine-grained granodioritic host rock. It is interpreted to be similar to the other boulders found in the area. The high-grade sample did not contain any other significant grades except for Fe and S (25.8 g/t Ag, 589 ppm As, 517 ppm Cu, 7.48% Fe, 47 ppm Pb, 3.83% S, 14 ppm Sb, 44 ppm Zn).

Preliminary Meffa (multi element fine fraction analysis) soils indicate discontinuous arsenic anomalies in the area. The possible sources of the boulders could be either the area of the disappearance of the arsenic anomaly approximately 100 meters northwest from the high-grade boulder, or the Barsele gold deposit itself. The first area is dominated by a volcanic-sedimentary sequence, with possible presence of narrow granodioritic intrusions.

There is also a graphite-sulphide bearing horizon present in the area, that can cause base-metal anomalies. All samples referred to in this news release were tested at independent MS Analytical Service, wherein core sawing and sample preparation is carried out in Storuman, Sweden and the analyses of both Au and multi-element analysis is completed in Canada. The assay method is SWED-Edh-6, which comprises:-FAS-121, Au fire assay-AA on 50 gram-above 3 ppm Au fire assay-gravimetric; FAS-425, Au by fire assay and gravimetric finish 50-gram nominal sample weight; IMS-230, 48 element four-acid digestion ICP-MS; ICF-6Xx, default over limit methods for ICF-6Ag, ICF-6As, ICF-6Cu, ICF-6Pb, ICF-6Zn, SPM-210 (S); FAS-418, Ag by fire assay and gravimetric finish for Ag above 1,000 ppm.

For semi-massive to massive sulphide rock, ICP-130 aqua regia is used for multi element analysis, instead of the four-acid digestion.
