BURLINGTON, 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.
- 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 conductor down dip from the intersections.
Chief Executive Officer Jean-Charles Potvin comments:
'The Betty Zone intersections, in conjunction with the newly discovered geophysical target horizon, are an exciting development on the property. The two drill holes completed at the Betty Zone narrowly missed the primary conductor and yet still intersected mineralization - there is extremely promising potential along the conductor. The Betty Zone is less than one kilometre away and is on strike with the Brabant-McKenzie deposit; the similar geophysical characteristics adds to the potential of the area.'

Results from additional drilling at the Brabant-McKenzie Deposit
Murchison has received the results from the remaining three drill holes (BM21-001, BM21-005, and BME21-001) completed at and proximal to the Brabant-McKenzie Deposit during the 2021 winter drill program (Figure 3). BM21-005 was designed to test the southern near-surface extents of the Deposit's lower domain and assess the viability of expanding the reported Inferred Mineral Resources within the upper domain; the hole successfully intersected 1.31 metres of 6.82% Zn Eq. BM21-001 was designed to test the rock mass directly south of the deposit to assess growth potential; the drill hole intersected two narrow intervals of sulphide mineralization from 222.15 to 222.92 metres and from 409.81 to 410.16 metres, indicating the area is prospective for potential resource growth (Table 1). BME21-001 was designed to test a small shallow isolated conductor directly east of the deposit. The hole intersected an interval of graphite and pyrrhotite mineralization, but no notable economic mineralization was encountered in the hole.

Sample Preparation and Analysis
Murchison has implemented and is adhering to a strict Quality Assurance/Quality Control program for the drilling program. NQ size core was drilled, and mineralized intervals were marked by geologists during core description. The marked intervals were sampled using a core saw, one-half is kept as a witness sample at Brabant Lake and the other assigned a unique number and placed within a plastic bag. The specific gravity of each sample was measured using the mass-in-air / mass-in-water method. Samples were shipped directly to SRC Geoanalytical Labs in Saskatoon, Saskatchewan. The samples were ground and prepared for analysis by the lab using total digestion. Analyzes were performed using ICP-OES for zinc, copper, lead, and silver. Gold was analyzed using fire assay. Every 25th sample sent to the lab was a field duplicate (quarter core), blanks and certified reference material were also submitted approximately every 25th sample.
SRC Geoanalytical Labs is accredited by Standards Council of Canada (Scope of accreditation # 537) and operates in accordance with ISO/IEC 17025, General Requirements for the Competence of Testing and Calibration Laboratories.
