Sterling Metals Advances Inaugural Field Exploration Campaign

at the Copper Road Project

June 26, 2024 – Toronto, Ontario – Sterling Metals Corp. (TSXV: SAG, OTCQB: SAGGF) (“Sterling” or the

“Company”) is pleased to announce that the inaugural Phase 1 exploration campaign at the Copper Road

Project (“ Copper Road” or the “ Project”) is well underway. Located 80km north of Sault Ste. Marie,

Ontario, Canada, Copper Road is a 2 5,000ha high-potential brownfield copper -molybdenum-silver-gold

project associated with the Midcontinent Rift, which until 2021 had never been fully consolidated . The

Project benefits from its strategic proximity to substantial infrastructure (Figure 1).

Highlights

• Given the extensive history of exploration and mining, as well as numerous surface copper

showings (Figure 2), the Phase 1 Exploration campaign, will take a wide systematic and optimized

approach to advance the full Project understanding in an effort to define targets for future drilling

across the land package (described further below).

• Several exploration activities were completed in May and June, ahead of schedule including:

o Property-wide 3,777-line kilometer airborne magnetic, radiometric and Lidar survey.

o Physical property testing to define geophysical signatures of targets.

o Commenced minimum 5,000 surface sample program across the Project.

• Advanced modeling of historical geophysical data to extract new important layers of data for

targeting and to map the plumbing of the mineralization is anticipated to be completed in July.

Jeremy Niemi, SVP Exploration and Evaluation at Sterling Metals, commented, “As we review core samples

from historical holes and explore previous mine sites, the immense geological opportunity at Copper Road

becomes clear. Consolidating this vast land pack age, leveraging historical data, and integrating it with

modern geophysics and surface mapping is an exploration geologist's dream. We are quickly advancing

our understanding of the porphyry and breccia systems and look forward to uncovering the riches thi s

project has to offer. We look forward to launching an exciting drilling program in the near future.”

Phase 1 Exploration Campaign

The field base is now set up and the field crew has commenced an extensive soil sampling and mapping

campaign (minimum of 5,000 samples to be collected). As a lead into the soil sampling campaign, the

Company completed two test lines in areas of known mineralization and with historical surface sampling.

The samples and in -house measurements of copper in soils provided an excellent correlation with

historical work and known mineralization.

The Company has also completed a property-wide helicopter airborne survey to collect high -resolution

magnetic signatures of the rocks, radiometrics data to map alteration related to copper porphyry's,

detailed LiDAR data to accurately map the topography and important structures related to mineralization.

The data will be used to build a 3-dimensional model of the geology across the Project which will assist in

identifying the plumbing of the copper-molybdenum porphyry and breccia pipes and to potentially locate

new targets for future drilling. Magnetic signatures of key rock types offer an excellent opportunity to

locate important geological units such as the mafic volcanics close to mineralization, similar to that seen

in historical hole AR96-01 drilled in 1996 (Figure 3), which play an important role in the accumulation of

copper sulphides. Mafic volcanic hosted copper sulphides in copper porphyry settings commonly host

higher grade mineralization and can be important types of copper deposits.

Jogran target

The Company has also initiated an advanced modeling of the existing VTEM survey over the central area

of the property, which has known copper-molybdenum porphyry and breccia hosted mineralization. This

work will extract new layers of geophysical data, including chargeability data from what is known as

airborne IP. The physical property testing has shown that the copper-molybdenum mineralization on the

property has a strong chargeability response and that this data is very important in targeting. Historically

there has been patchy ground IP completed on the property (Figure 4). Utilizing the airborne IP layer, the

Company will have a larger area of coverage and aim to identify new high chargeability zones yet to have

been drilled. This advanced modeling work of the VTEM survey is expected to be completed by early July

2024. Based on the results of this work , the Company anticipates completing an advanced modeling of

the existing ZTEM survey, which would add deep reaching resistivity data to the regional targeting model.
