Benchmark Advances Environmental Baseline

Studies Towards Environmental Assessment

and Mine Permitting

Edmonton, Alberta--(Newsfile Corp. - April 11, 2023) -

Benchmark Metals Inc.

(TSXV: BNCH) (OTCQX:

BNCHF) (WKN: A2JM2X) (the "

Company

" or "

Benchmark

") - is pleased to provide an update for the

Lawyers Gold-Silver Project ("Lawyers" or the "Project"). This press release serves as an update from

the Company on the Environmental Baseline Study work currently in progress. Benchmark is in the final

year of a 2-Year Environmental Baseline Program which includes aquatics, terrestrial, and geochemical

data collection. This Program will serve as the basis for an effects assessment to support an upcoming

Environmental Assessment (EA) application. Benchmark's flagship Lawyers Gold-Silver Project (the

"Project") is located within a road accessible

region of the prolific Golden Horseshoe area of north-

central British Columbia, Canada.

Environmental Baseline Studies are a comprehensive assessment of the environmental conditions in a

specific area prior to the construction of a proposed project. They are designed to document the existing

environmental conditions of the area, including air, water, soil, and biotic resources, and serve to

establish a baseline that can be used to assess the potential impact of a proposed project.

Environmental Baseline Studies are an essential part of the EA process and help to ensure that mining

companies operate in a conscientious and sustainable manner.

John Williamson, President & Director, commented, "As a responsible mineral exploration company, we

understand the importance of protecting the environment and the communities in which we operate. The

baseline studies will provide important information that will inform our decision-making and help us to

minimize our impact on the environment. We are committed to working closely with our First Nations,

local communities, government agencies, and environmental groups to ensure that our operations are

carried out in a sustainable and responsible manner. The Studies, along with the ongoing post-PEA

optimization efforts, will result in a more robust mine plan that is acceptable to mine permitting

regulators."

The 2023 Environmental Baseline Program builds upon the programs initiated in June 2021, in addition

to the baseline work completed throughout 2022. The baseline efforts to date have highlighted some of

the Project's major strengths, including road access to site with potential for year-round access, local

airstrip immediately south of site (Sturdee Airstrip), brownfield site with majority of proposed

infrastructure located in previously disturbed areas, very compact site layout with the majority of

infrastructure and mining located above the tree line, skilled local workforce and positive relations with

First Nations.

The 2023 Program will be split into terrestrial, aquatics and geochemical programs. The following

sections outline the major objectives of the 2023 Programs.

Aquatic Baselines

Aquatics data collection is led by Chu Cho Environmental, in partnership with Palmer Environmental

Consulting Group and includes ongoing sampling of:

Surface Water Quality;

Surface Water Quantity;

Groundwater;

Aquatic Resources, and;

Fish and Fish Habitat.

The Aquatic Baseline Program for 2023 aims to achieve the following:

Complete analysis and presentation of existing conditions to guide project planning and

development; thus, providing opportunities to minimize impacts to the environment.

Provide support in planning for all phases of mine life (characterization of historical and existing

environment, EA and permitting, construction, operation and closure); and

Maximize Project benefits to Tsay Keh Dene Nation, Kwadacha Nation, Takla Nation, and Tahltan

Nation members through training and capacity building.

Since the project is currently in the exploration phase, data collected in 2021, 2022 and 2023 will be

used to characterize existing aquatic conditions. The aquatic baseline program was developed to meet

the requirements of the Water and Air Baseline Monitoring Guidance Document for Mine Proponents

and Operators (BC MOE 2016). The baseline conditions will be used to inform mine planning and

development to avoid or minimize environmental effects, where possible. In addition, the existing

conditions documented in the aquatic baseline program will provide the basis for the environmental

effects assessment of the mine plan.

Terrestrial Baselines

Terrestrial data collection is led by Chu Cho Environmental, in partnership with EcoLogic Consultants

Ltd. and includes characterization of:

Terrain and Soils;

Ecosystems and Vegetation;

Wildlife and Wildlife Habitat;

Air Quality and Noise, and;

Meteorology.

The Terrestrial Baseline Program for 2023 aims to achieve the following:

Complete analysis and presentation of existing conditions to guide project planning and

development; thus, providing opportunities to minimize impacts to the environment;

Provide support in planning for all phases of mine life (characterization of historical and existing

environment, EA and permitting, construction, operation and closure), and;

Maximize Project benefits to Tsay Keh Dene Nation, Kwadacha Nation, Takla Nation, and Tahltan

Nation members through training and capacity building.

The Studies have been developed consistent with requirements of the metal mining technical guidance

for Environmental Effects Monitoring (Environment Canada 2012) to assess potential future effects to the

receiving environment. The environmental baseline program will document biophysical conditions prior

to mine construction for comparison with post-development conditions as part of the mine's

environmental effects monitoring plan to support Environmental Assessment process required for

developing the project.

Geochemistry

Geochemical data is being collected by pHase Geochemistry and includes static testwork (completed in

2022) and ongoing kinetic testwork (humidity cells initiated in Q4 2022).

The objective of the static testwork geochemical characterization program is to develop a baseline

geochemical understanding of the potential for metal leaching and acid rock drainage (ML/ARD) from all

of the Project's potential waste rock sources. Furthermore, the results will comprise the environmental

baseline studies and the FS level understanding to support design and ultimately permitting of the

project. To-date, the static testwork results show low acid-generation potential for all tested materials.

The kinetic testwork program is considered the second stage of the geochemical characterization and

provides baseline information on the kinetic characteristics of samples exposed to lab-based

weathering conditions. This includes sulphide oxidation rates, neutralization potential depletion and

metal release rates from waste rock. Kinetic test results are a requirement of permitting for any project

and are necessary inputs for the development of water quality predictions and waste management

planning. The implemented kinetic testing program consists of a laboratory-based humidity cell test

program. Preliminary results indicate Lawyers waste rock material will be classified as "non-PAG" (i.e.,

"non-potentially acid-generating").
