[{"type":"text","content":"Murchison Minerals Ltd. Defines Highly Prospective Borehole Geophysical Anomaly at its Newly Acquired Betty Target, Intersecting 9.22% Zn EqBURLINGTON, ON / ACCESSWIRE / April 13, 2021 / Murchison Minerals Ltd. (\"Murchison\" or the \"Company\") (TSXV:MUR) is pleased to announce it has located a large, highly prospective, off-hole borehole geophysical anomaly at its newly acquired Betty Zone target located approximately one kilometre northeast of the Brabant-McKenzie Deposit (Figure 1 & 2). Two holes, BZ21-001 and BZ21-002, were recently drilled during the 2021 winter drill program at the Betty Zone and were later surveyed by a borehole electromagnetic (EM) survey at the end of the 2021 winter drill program. The resulting data indicates that the holes narrowly missed a large conductive body located immediately down dip and is approximately 100 to 300 metres below surface (Figure 4 & 5). Initial modelling suggests the anomaly has the potential of a 700 m long strike length, that is also supported by airborne VTEM data. The anomaly is directly on strike with the Brabant-McKenzie Deposit with similar conductivity values. Murchison is extremely excited to drill test the newly defined target and is optimistic it will yield positive results.BZ21-001 (381 metres) and BZ21-002 (330 metres) both intersected volcanogenic massive sulphide (VMS) mineralization similar to what is observed at the Brabant-McKenzie Deposit (Figure 3 & 6). The observed mineralization consists of an interval of abundant sphalerite and chalcopyrite and is located proximal to the observed off-hole borehole geophysical anomaly. The intersected mineralization is poorly conductive and only produced a minor EM response. Sphalerite is a non-conductive mineral and the intercept lacked significant pyrite or pyrrhotite which are the common cause of conductivity in massive sulphide deposits. It is interpreted that measured off-hole EM response is caused by more substantial sulphide mineralization further down dip.Highlights:Hole BZ21-002 intersected 4.40% Zn, 1.33% Cu, 12.95 g/t Ag from 280.73 to 281.65 metres (0.92 m) including 0.42 m at 3.76% Zn, 2.40% Cu, 21.70 g/t Ag and 0.12 g/t Au (12.41% Zn Eq).Hole BZ21-001 intersected 3.59% Zn, 0.21% Cu, 5.30 g/t Ag from 327.25 to 327.54 metres (0.29 m).Downhole EM indicates the presence of a significant off-hole conduc...
