TORONTO, ON / ACCESSWIRE / March 6, 2023 / Sterling Metals Corp. (TSXV:SAG and OTCQB:SAGGF) ("Sterling Metals", "SAG" or the "Company") is pleased to announce that it has entered into an option agreement (the "Agreement") dated March 6, 2023, with Chesterfield Resources Plc. (LSE:CHF, "Chesterfield") and its wholly owned subsidiary Chesterfield (Canada) Inc. ("Chesterfield Canada") and together with Chesterfield (collectively, the "Optionors") pursuant to which SAG has been granted the exclusive option to acquire 100% of the Adeline Copper-Silver Project ("Adeline" or the "Project") in Labrador, Canada (Figure 1).
Highlights of the Adeline Copper-Silver Project:
- 297 km2 district-scale land position prospective for sediment-hosted high-grade copper and silver mineralization with 44 km of strike length of the target stratigraphic horizon (Adeline Island Formation);
- Strong geological comparisons with preferred epigenetic sediment-hosted copper deposits such as Udokan (estimated reserves of 1.2 Bt at 2% Cu;
- Robust early-stage exploration database including Mag/IP/Resistivity and over 250 copper samples assaying as high as 26.9% Cu (see Figure 2);
- Pipeline of exploration targets at different stages of development including two drill-ready targets at two key prospects, one of which has returned an encouraging intercept of 1.76% Cu and 58.2 g/t Ag over 7.9 m on the edge of a large chargeability anomaly (2011, Playfair hole SL-11-10); and
- Project located close to road, rail, and power infrastructure and within 500 km of the Sail Pond project allowing for strong economies of scale for exploration.

Mathew Wilson, CEO of Sterling Metals commented, "Our focus is to establish the foundation for a successful Canadian mining company in one of Canada's most favourable yet underexplored districts. Canada was once a global leader in copper production but has since fallen off the map due to a lack of new high grade greenfield discoveries. As the country looks to enhance its domestic security of supply of critical metals, new large-scale high-grade discoveries in metals such as copper, silver, and to some degree zinc and antimony, sticks out as a key missing piece.
With the option of Adeline, we will now have two assets that possess these attributes within a 30-minute flight of one other. We eagerly await the initial results of our Orion survey at Sail Pond which looks to show the true size potential at depth of the polymetallic, silver and copper rich system.
I want to also take this time to welcome Chesterfield and its shareholders to Sterling. I am confident that by the end of 2023, we will all have come a long way towards recognizing the true potential of both of these exciting assets."
Dr. Neil O'Brien, Technical Advisor to Sterling Metals commented, "Adeline is an excellent entry point to a mid-stage exploration project covering an entire sediment-hosted copper belt and will be an exceptional complement to Sterling's portfolio. Previous work has clearly demonstrated its potential for important new copper discoveries with significant silver credits. There are distinct similarities to many of the world's great sediment-hosted copper deposits and belts including very rich copper ore mineralogy, efficient metal traps needed to form economic copper-silver deposits, and km-scale strike extents of prospective geology with hundreds of copper showings that allow for multiple camp-scale discoveries. With a rich exploration and research database, we look forward to leveraging our deep understanding of the project to develop smart drill targets in a cost-effective and timely manner."

The Adeline Copper-Silver Project
Comprised of roughly 30,000 hectares and a 44 km strike of copper-silver-rich terrain, the Adeline project covers the youngest middle Mesoproterozoic volcano-sedimentary sequences, known as the Seal Lake Group. The Seal Lake Group consists of supracrustal argillaceous and arenaceous sedimentary rocks, intercalated with basalt flows and intruded by gabbro sills. The volcano-sedimentary rocks formed as a result of extensive continental sedimentation from the transition from subaerial to shallow-marine during a rift-related cycle of uplift and erosions.
Structurally, the Seal Lake Group rocks are in thrust contact with the Paleoproterozoic granitoids of the Trans-Labrador batholith to the south. Immense structural deformation related to the 1.3 to 1.0 Ga collisional development of the Rodinia supercontinent, resulted in stratigraphic repetition of the sequences and complexly folded the group into an east-trending, doubly plunging syncline that is 120 km long and 45 km wide. The southern limb of the syncline has been overturned and thrust northward during Grenville Orogeny deformation (ca. 1.0 Ga). The western side of the syncline exhibits more intense deformation with tighter folds than the eastern side (Altius, Seal Lake Copper Project Technical Report, 2015; T.S. van Nostrand, Geology of the Seal Lake area, 2010).
The Adeline Project sediment-hosted copper-silver mineralization formed in response to the same globally significant geological event, the Grenville Orogeny, which formed the giant copper deposits of the Keweenawan Copper Belt in Michigan and contributed to the formation of the significant copper deposits of the Zambian and Kalahari Copper Belts.
The sediment-hosted copper deposit class is attractive as it can yield orebodies that host large tonnages similar to porphyry copper deposits but with significantly higher grades, an example of which is KGHM's Lubin Mine in Poland, the most significant mine in the Kupferschiefer copper district, in production since 1968 and hosting 2.6 billion tonnes of ore grading 2% copper. At Adeline, both the geological setting and the style of copper mineralization suggest a favourable environment for hosting sediment-hosted stratabound copper deposits.

Copper mineralization at Adeline is structurally controlled, and commonly associated with quartz +/- carbonate veins in a manner similar to that at Udokan, Russia, and is greatly influenced by the oxidation state of the various rock types (oxidized vs reduced) (Altius, Seal Lake Copper Project Technical Report, 2015). The mineralization occurs in two distinct styles:
- As bedding, foliation and cleavage parallel, fine-grained disseminated masses of chalcocite ± bornite ± chalcopyrite that grade into stratiform lenses of similar composition in the grey, green to black shales. Also present are chalcocite ± bornite ± chalcopyrite stringers and quartz-carbonate veins in diabase and basalt, as well as in the grey, green to black shales, arenite and phyllite (reduced "grey beds"). Mainly present in the Adeline Island Formation.
- Native copper-bearing quartz-carbonate veins within the red slate and/or strongly hematized basalt units of the Salmon Lake, Whiskey Lake and Wuschusk Lake formations.
Infrastructure and Jurisdiction
This Project maintains many advantages in the event of future development. Newfoundland and Labrador remain a top 10 jurisdiction for mining as pre the Fraser Institute. The Project is easily accessible by helicopter from Goose Bay. The Trans-Labrador highway is approximately 112 km away, a hydro access road is 61 km away, and the 5,428 MW Churchill Falls power station is 180 km away.
