Murchison Minerals Ltd. Defines Highly Prospective Borehole

Geophysical Anomaly at its Newly Acquired Betty Target,

Intersecting 9.22% Zn Eq

April 13, 2021 (Burlington, Ontario): 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 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.
