Sterling Metals Provides Update on its Phase 1 Exploration Campaign

at the Copper Road Project

August 20, 2024 – Toronto, Ontario – Sterling Metals Corp. (TSXV: SAG, OTCQB: SAGGF) (“Sterling” or

the “Company”) is pleased to provide an update on its inaugural Phase 1 exploration campaign at its

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

Canada, Copper Road is a 25,000ha high -potential brownfield copper -molybdenum-silver-gold project

associated with the Midcontinent Rift. The Project benefits from its strategic proximity to substantial

infrastructure, extensive historical database and excellent project access.

Highlights

• Multiple high-priority, multi-kilometer copper exploration zones have been identified and are

currently being evaluated and advanced using a combination of soil trend analysis, magnetic

signature data, LiDAR mapping, historical records, and new prospecting efforts.

• Extensive exploration completed in Phase 1 in July includes:

o Collected 1,200 surface soil samples with strong copper -molybdenum anomalies

emerging (Figure 1).

o Inversion of property-wide 3,777-line kilometer airborne magnetic survey.

o Advanced modeling of historical airborne electromagnetic (EM) survey data, including

extraction of airborne induced polarization.

o Initiated interpretation of a new 10cm resolution LiDAR survey:

▪ Preliminary results identified extensive historical occurrences including 483 pits,

227 trenches, 12 adits, and 10 shafts across the property (Figure 2).

▪ Geological contacts and key structural features are now being interpreted

o Completed digitization of over 200,00 pages of historical documents from the last 60

years.

• Advancing newly defined targets with continued mapping and sampling which have abundant

outcrops and showings:

o Early stages of mapping have been encouraging with numerous showings with copper

sulphide mineralization in the form of chalcopyrite and bornite and often associated with

molybdenite and other metal minerals such as magnetite.

• Existing trails leading to target areas are being cleared and reopened as the Company

progresses with its soil program and prospecting.

• All efforts continue to prioritize targets for ground geophysics as the Company looks to source

potential high tonnage targets associated with the high grade breccias and porphyry system

demonstrated most recently via drill holes J2302 and R2301 (see Figure 1).

Jeremy Niemi, SVP Exploration and Evaluation of Sterling Metals, commented, “The rapid progress we've

made in advancing the Project and identifying priority copper exploration zones puts us an excellent

position since closing the transaction with Copper Road Resources in May. It is incredibly rewarding to

systematically integrate our new data with historical knowledge and then discover new copper showings

at the surface. Our focus now shifts to pinpointing large -scale copper targets within this extensive

mineralized area and advancing the priority drill targets.”

Phase 1 Exploration Campaign

The Phase 1 exploration campaign at the Copper Road Project is progressing with several key activities.

Soil sampling is being extended northwest of Richards Breccia, on the west side of Mamainse Lake, as well

as northeast towards the Tribag mine. These areas are being targeted to expand the understanding of the

copper mineralization potential across the Project (see Figure 1).

Geophysical targets are also being actively field -tested. Several new outcrops, which appear to contain

porphyry vein types similar to those found at Jogran, have been identified. Samples from these outcrops

have been collected and sent to the lab for assays, with the results expected to provide further insights

into the mineralization system.

In addition to fieldwork, further interpretations of Li DAR, magnetic surveys, ZTEM, VTEM, and

radiometrics are ongoing. These efforts are being integrated with current soil and rock sample data, as

well as historical drilling and mining operations. The goal is to refine the targeting and focus on higher -

impact zones that could host large tonnage and economically viable copper mineralization.

Mathew Wilson, CEO of Sterling Metals commented, “The more data we uncover, the more we appreciate

the successful and widespread exploration efforts dating back to the early 1960s. Although we have only

been on this Project for a few months, the results have been highly encouraging, and the scale of the

potential targets far exceeds our initial expectations. To find large mines you need large mineral systems

and there is no doubt that this is a very large copper system. Our work is now allowing us to hone in and

explore new areas that could be potential sources for the extensive copper-molybdenum-gold and silver

zones across this large area. We are excited to keep the market informed as we advance towards our

maiden drill campaign."
