(\"Murchison\" or the \"Company\") (TSXV: MUR) is pleased to announce that it has identified new EM targets approximately 400 metres from the Murtack showing where historical grab sampling reported significant grades of zinc, copper, molybdenum, lead, silver and minor gold.The Murtack showing was acquired as part of the significant land holdings expansion at and around the Brabant Lake project in north-central Saskatchewan over the last four months. It is located approximately 14.4 kilometres southwest of Brabant Village.M. Murtack first prospected the area in 1965 when the mineralized showing was discovered (AF 74F01-0004). Sand blasting of gossan-covered outcrops and the digging of a test pit exposed a shear zone containing pyrite, pyrrhotite, sphalerite, galena, and graphite mineralization. A geological survey, some soil sampling and six diamond drill holes totaling 460 metres were completed in the area. The main occurrence is one of four gossan zones extending over a strike length of 1006 metres. Sulphides zones vary from 1.5 to 14.0 metre wide.Ten grab samples collected at that time returned trace to 0.54% Cu, 0.25 to 1.55% Zn, trace to 0.11% Pb, 0.02 to 0.36% MoS2, 0.17 to 1.4 g/t Au and 0.34 to 34.4 g/t Ag. Grab sample No. 3 returned trace Cu, 6.6% Zn, 36.11% Pb, 0.5% MoS2, 1.4 g/t Au and 160 g/t Ag. A selected grab sample taken by W.G.Q. Johnston in 1965 containing a high percentage of sulphides assayed 0.13% Cu and 40.8% soluble Fe. (Source: Johnston, W.G.Q., (1968) DMR Report No. 106, p45)The area remained inactive until 1973, at which time, electromagnetic and magnetic surveys were completed over the gossan zones. The magnetic survey delineated a narrow conductive horizon with pyrite-pyrrhotite-graphite mineralization, which corresponds to the showing. No further work was reported since 1975 until Murchison staked the area in December 2018 and subjected it to a VTEM heliborne survey completed by Geotech in January 2019.This recent heliborne VTEM survey confirmed that both gossan #1 and #4 are coincident with a northwest dipping conductor. Conservatively, the strike length could be in excess of 1,000 metres. If it is related to the southwest extent on L3160 (last...
