Edmonton, Alberta--(Newsfile Corp. - June 13, 2022) -
Benchmark Metals Inc.
(TSXV: BNCH) (OTCQX:
BNCHF) (WKN: A2JM2X) (the "
Company
" or "
Benchmark
") is pleased to announce a significant
increase to its global bulk-tonnage Mineral Resource Estimate (MRE) for its flagship Lawyers Gold-
Silver Project. The MRE comprised of 1,097 drill holes totaling 200,000 metres collectively from the Cliff
Creek, AGB and Dukes Ridge deposits were used for Mineral Resource Estimation. The 100% owned
Lawyers Gold-Silver Project is located within a road accessible
region of the prolific Golden Horseshoe
area of north-central British Columbia, Canada.
John Williamson, CEO, commented, "The expanded Mineral Resource Estimate is demonstrating the
world-class potential of Benchmark's multi-million-ounce gold-silver deposits. The Company has
provided one of the highest-grade, open pitable mining projects in North America. The 2021 drill
program and winter 2022 drill program has significantly de-risked the project with approximately 90
percent of the Mineral Resource within the Measured + Indicated classification. With the deposits open,
further resource growth is possible and the Project has numerous targets that may develop into near
mine satellite deposits. The company has drilled-out a significant amount of gold and silver ounces that
is not included in the $1700 pit shell. At higher precious metals prices, the contained gold increases
significantly. The MRE comprises of proven economically minable material while the remaining, outside
of pit gold and silver will provide a significant opportunity as the price of precious metals increases."
Ian Harris, VP Engineering, commented, "The Project is demonstrating potential for economic mining
methods with high-grade mineralization extending from surface to depth. The higher-grade core zones at
surface will have a positive impact on economics in the forthcoming Preliminary Economic Assessment
(PEA). Benchmark's drill-to-build philosophy is delivering the results to develop the Project into a world-
class gold-silver mine located in one of the best mining jurisdictions in the world."
Benchmark Metals invites you to a webinar to discuss the Mineral Resource Estimate on Tuesday, June
14

Notes:
1
.
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
2
.
The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political,
marketing, or other relevant issues.
3
.
The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and
must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could potentially
be upgraded to an Indicated Mineral Resource with continued exploration.
4
.
The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM
Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing
Committee on Reserve Definitions and adopted by the CIM Council.
5
.
Historical mined areas were removed from the block modelled resources.
6
.
Metal prices used were US$1,750/oz Au and US$20/oz Ag and 0.78 US$ICDN$ FX with process recoveries of 90% Au and 83% Ag. A
C$14.50/t process cost and C$5/t G&A cost were used. The Au:Ag ratio was 80:1.
7
.
The constraining pit optimization parameters were C$3.15/t mineralized and waste material mining cost and 50° pit slopes with a 0.30 g/t
AuEq cut-off.
8
.
The Out-of-Pit Mineral Resource grade blocks were quantified above the 1.5 g/t AuEq cut-off, below the constraining pit shell and within
the constraining mineralized wireframes. Out-of-Pit Mineral Resources selected exhibited continuity and reasonable potential for
extraction by the long hole underground mining method.
9
.
A new NI 43-101 technical report will not be produced as the total tonnage or total contained metal have not materially changed. An NI 43-
101 technical report will be produced with updated Mineral Resources in conjunction with a PEA.

Indicative Starter Pits
'Indicative Starter Pits' are provided within two of the deposits with higher-grade Mineral Resources
located at surface. The AGB Deposit contains 7.5 million tonnes at
1.74 g/t AuEq
for approximately
418,000 oz AuEq at a strip of 1.7:1
. A second Starter Pit at the Cliff Creek Deposit has generated 5.2
million tonnes at
1.74 g/t AuEq
for approximately
292,000 oz AuEq at a strip of 2.2:1
. The 'Starter
Pits' provide high quality mineralization with an expected low strip ratio at surface that has generated
clean sulphide mineralogy free of deleterious elements with 93% gold metallurgical recovery. The Starter
Pits contain lower strip ratios that result in mining less total material to generate improved economics in
the initial years of mining.
Additional Mineral Resource Expansion Potential
Ongoing drilling is focused on open extensions of near surface, high-grade mineralization. Recent
results, that were not included in the MRE are providing additional Mineral Resource expansion potential
in several key areas including Dukes Ridge and Cliff Creek Mid. The Dukes Ridge Deposit recently
generated positive results yielding 54.60 metres of 2.51 grams per tonne (g/t) gold and 97.05 g/t silver
or 3.73 g/t AuEq, including 9.60 m of 13.39 g/t gold and 480.26 g/t silver or 19.39 g/t AuEq (
see June 2,
2022
news release
). The deepest holes drilled at Dukes Ridge to date have extended mineralization,
which remains open to nearly 300 metres vertical depth. In addition, the 20 kilometre long mineralized
trend has provided clusters for multiple satellite deposits that require drill testing for additional new
discoveries and Mineral Resource growth.
Near-Term Advancement to Mining
The historical mining footprint has logistical and structural advantages
set within the mining district
featuring access to highway, abundant and low-cost hydroelectric green power, fresh water, labour and
in a Tier 1 mining jurisdiction that has proven world-class mines. Benchmark anticipates completion of
the Preliminary Economic Assessment (PEA) during Q3, 2022. The Company has already completed
significant progress with the PEA and includes recent metallurgical test work reconfirming an industry
standard processing flowsheet with gold achieving 93% recovery. The Company has received initial
geochemistry static test work for environmental analysis of waste rock and mineralized rock. To date,
mineralized rock and waste analysis show insignificant and benign impacts to the environment. The
majority of engineering work is completed, pending optimization of the mine plan and schedule. The
PEA mine schedule will include the at surface, Starter Pit areas of higher-grade gold and silver
mineralization and lower associated strip ratios. The core zones and initial starter pit areas have
potential to positively impact the initial years of mining in the PEA.
The majority of engineering tasks to support development of the Feasibility Study ("FS") are in progress
or complete.
Significant outstanding activities include on-going geotechnical work for major
infrastructure, and geochemical test work. Additional work has focused on mine optimization and trade-
off studies to determine robust economics and engineering efficiencies.
Measured and Indicated Classification
Benchmark has de-risked the gold and silver ounces by elevating the quality of the total Mineral
Resource to the Measured and Indicated classification. The term "Measured & Indicated Mineral
Resource" refers to that part of a Mineral Resource for which quantity, grade or quality, densities, shape
and physical characteristics can be estimated with a level of confidence sufficient to allow the
appropriate application of technical and economic parameters to support mine planning and evaluation
of the economic viability of the deposit. The estimate is based on drill holes that are spaced closely
enough for geological and grade continuity to be reasonably assumed. The new MRE is at a sufficient
classification to be utilized in the Feasibility Study for 2023.
Quality Assurance and Control
Results from samples were analyzed at ALS Global Laboratories (Geochemistry Division) in Vancouver,
Canada (an ISO/IEC 17025:2017 accredited facility). The sampling program was undertaken by
Company personnel under the direction of Rob L'Heureux, P.Geol. A secure chain of custody is
maintained in transporting and storing of all samples. Gold was assayed using a fire assay with atomic
emission spectrometry and gravimetric finish when required (+10 g/t Au). Analysis by four acid digestion
with 48 element ICP-MS analysis was conducted on all samples with silver and base metal over-limits
being re-analyzed by atomic absorption or emission spectrometry. Rock chip samples from
outcrop/bedrock are selective by nature and may not be representative of the mineralization hosted on
the project.
