MURCHISON UPDATES BRABANT-MCKENZIE MINERAL RESOURCE, INCLUDES

7.6 MILLION TONNES INFERRED GRADING 6.29% ZN EQ AND 2.1 MILLION TONNES

INDICATED GRADING 9.98% ZN EQ

Toronto, ON– September 13, 2018 - Murchison Minerals Ltd. (MUR - TSXV) (“Murchison ” or the “Company”) is

pleased to provide the results of the updated Mineral Resource estimate (the “September 4, 2018 Mineral Resource

Estimate” or the “Estimate”) for the Brabant-McKenzie Deposit (the “Deposit”) located in north-central

Saskatchewan.

The September 4, 2018 Mineral Resource Estimate was performed by Finley Bakker Consulting, of Campbell River, BC.

The new estimate includes the addition of 19 new diamond drill holes totaling 9,004 m which were completed

between January and March 2018 by Murchison as well as a comprehensive re-interpretation of the geology of the

Deposit using current, historical drilling data and reports.

The September 4, 2018 Mineral Resource Estimate was calculated using Minesight/Hexagon 3D modeling software to

define the mineralized limits of the Deposit. The results will now be used to further systematically define future

exploration programs for the Deposit.

Highlights Include:

• Total Indicated Mineral Resources of 2.1 million tonnes at 7.08% Zn, 0.69% Cu, 0.49% Pb,

39.60 g/t Ag or 9.98% Zn Eq

• Total Inferred Mineral Resources of 7.6 million tonnes at 4.45% Zn, 0.57% Cu, 0.19% Pb,

18.40g/t Ag or 6.29% Zn Eq

• Drilling provided significant confidence in the continuity of the mineralized zone

• New resource calculation is based on 19 diamond drill hole program, visual inspection and

re-examination of previously drilled core and ongoing review of historical drill records

• The extents of the deposit are not yet fully defined including to depth and laterally

• Based on the current geological model, further work will focus on designing next steps

exploration including additional follow-up drill programs

The September 4, 2018 Mineral Resource Estimate for the Deposit is provided in Table 1.

Murchison’s CEO and President Kent Pearson stated: “We are excited with the results of the 2018 resource estimate

update as we continue to meet our objectives and successfully build on last year’s work on the Brabant-McKenzie

Deposit. We believed this Deposit had room for further growth from the previous resource estimate and the increase

in the Brabant-McKenzie resource estimate is significant as it demonstrates the potential for a robust deposit. Our

geological modelling continues to outline and confirm the mineral continuity and the high-grade nature of the

Deposit. Results from this program will be used to design next steps for exploration including additional drilling. We

are focused on advancing the Deposit to a stage which is intended to allow us to begin applying economics to it in an

effort to determine its viability for development.

Our team is committed to advancing the Brabant-McKenzie Deposit based on sound exploration methods and prudent

allocation of financial resources as we work to deliver value for our shareholders.”

Technical Report

The September 4, 2018 Mineral Resource Estimate has been prepared by independent qualified person (“QP”) Finley

Bakker, P.Geo., and has an effective date of September 4, 2018. The completed Technical Report, presented in

standard form prescribed by Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects will

be published on Murchison’s web site and SEDAR www.sedar.com within 45 days of this news release. The

September 4, 2018 Mineral Resource Estimate was classified into Indicated or Inferred categories in accordance with

the CIM Definition Standards on Mineral Resources and Reserves (CIM Definition Standards) adopted by CIM Council

on May 10, 2014.

Table 1. Mineral Resource Summary for Brabant-McKenzie Deposit

Category Tonnes Zn% Cu% Pb% Ag (g/t) Zn Eq%

Indicated 2,100,000 7.08 0.69 0.49 39.6 9.98

Inferred 7,600,000 4.45 0.57 0.19 18.4 6.29

2018 Drill Program

The focus of the 2018 diamond drill program was to test potential mineralization both laterally and down dip of the

previously modeled resource as well as to upgrade inferred resources to the indicated resource category (Figure 1)

Drilling was successful in both aspects and provided significant confidence in the continuity of the mineralized zone.

The new resource calculation is based on a 19-diamond drill hole program, visual inspection and re-examination of

previous drilled core and ongoing review of historical drill records.

Details of the September 4, 2018 Mineral Resource Estimate

• 2018 Mineral Resource Estimate tonnage has been rounded to reflect the accuracy of the

estimate, and numbers may not add due to rounding.

• Mineral Resources are not Mineral Reserves and do not have demonstrated economic

viability. There is no certainty that all or any part of the Mineral Resources will be

converted into Mineral Reserves.

The resource for the Brabant-McKenzie Deposit was estimated on the basis of:

• Drilling results to March 24, 2018 and including historical diamond drilling used in the

previous NI-43-101 resource estimates completed in 2008 and 2018

• US$ metal prices of $1.20/lb Zn, $2.50/lb Cu, $1.00/lb Pb, $16.00/oz Ag and $1200/oz Au

• CDN$:US$ exchange rate of $1.20

• An NSR cut-off of $90/tonne or 3.5% Zn equivalent based on above metal prices

• Average metallurgical and payable recovery of 75% was used for all metals

• Indicated Resources were calculated using a two-hole minimum and a maximum distance of

60 m from a diamond drill hole

• Inferred Resources were calculated using a no hole minimum and a maximum distance of

200 m from a diamond drill hole

• The Resources were also manually reviewed and adjusted to take into consideration drill

intercepts from pervious operators drill programs in the areas of drilling carried out by the

Company

• As much as possible a 2-meter intercept minimum was used but was not strictly adhered to

• 138 drill holes used in the calculation and which were used to model two mineral lens

Next Steps Program

The results of the updated resource estimate and overall geological model will be used to assist in designing next

steps for the exploration program on the Deposit’s advancement including additional follow-up drill programs. There

are no known legal, political, environmental or other risks that could materially affect the potential development of

the mineral resources.

QA/QC

The core was logged and split in a secured core logging facility. Individual samples were labelled, placed in plastic

sample bags and sealed. Groups of samples were then placed in security sealed bags and shipped directly to the

Saskatchewan Research Council Laboratories ("SRC") in Saskatoon, Saskatchewan for assay analysis. SRC used the

ICP3 Base Metal Exploration Package for analysis. Check assays were undertaken by ALS Labs located in Vancouver

B.C. Assay results for both methods were acceptable. SRC and ALS are independent of the Company. Both SRC and

ALS are ISO17025 accredited.
