Sterling Metals Drills Newly Discovered Heimdall Zone at Sail Pond Silver and Base Metal Project

February 23, 2022 – Toronto, Ontario – Sterling Metals Corp. (TSXV: SAG) (“Sterling Metals” or the “Company”) is pleased to report results from its phase 2 drilling on the south zone of the Sail Pond Silver and Base Metal Project in the Great Northern Peninsula of Newfoundland. The company will be hosting a zoom webinar at 10am EST on Thursday February 24, 2022, to discuss these findings in more detail. Registration for the event can be found at:

Significant drill results are listed below:

  • 144.0 g/t Ag Eq over 12.2 m (52.6 g/t Ag, 0.019 g/t Au, 0.21% Cu, 0.93% Pb, 0.06% Sb, & 0.33% Zn) in hole SP-21-034 beginning at 148.8 m downhole; and

  • 851.98 g/t Ag Eq over 1m (300.17g/t Ag, 0.077 g/t Au, 1.34% Cu, 1.21% Pb, 0.35% Sb, 4.80% Zn) within a broader interval of 78.8 g/t Ag Eqover 19.8m (28.51 g/t Ag, 0.01 g/t Au, 0.13% Cu, 0.15% Pb, 0.03% Sb, & 0.40% Zn) in hole SP-21-038 beginning at 75.5 m downhole; and

  • 963.0 g/t Ag Eq over 1.0 m (378 g/t Ag, 0.133 g/t Au, 1.20% Cu, 6.29% Pb, 0.38% Sb, & 2.41% Zn) within a broader interval of 74.44 g/t Ag Eqover 16.09m (29.22 g/t Ag, 0.011 g/t Au, 0.092% Cu, 0.45% Pb, 0.029% Sb, & 0.21% Zn in hole SP-21-039 beginning at 99.47 m downhole.

Mathew Wilson, CEO of Sterling Metals, commented: “With the high silver equivalent grades returned from the final holes of the 2021 drill program, we continue to take steps towards the discovery of a significant silver and base metal district. The Sail Pond project lends itself to a deposit model analogous to a string of pearls with several deposits situated along the 12km anomaly. We believe that in just our first program we have discovered the top of the first pearl. The next steps are to follow these structurally controlled higher-grade structures down plunge and along strike, and then to repeat this process along the entirety of the trend.”

Sail Pond Drilling

Sterling’s maiden drilling program on Sail Pond was designed to test several regional targets defined by soil sampling, trenching, prospecting, and geophysics along ~12 km of prospective strike length, subdivided into the North and South Zones. Today’s results come from drillholes targeting a significant zone of mineralization within the South Zone (see Sterling press releases dated September 27 & October 7, 2021). The zone, which is hosted by dolostone, occurs in close proximity to a structural kink or jog in the contact of the host dolostone and the footwall argillite. Today’s results show the correlation of mineralization within this flexure zone. A large mineralized system, now called the Heimdall Zone, is becoming apparent and characterized by a broad zone of low grade precious and base metals associated with breccia-style or veinlet-style sulfide mineralization. The current dimensions of the lower grade zone are approximately 400 metres of strike, 200 metres of depth, and 80 metres of width. The Heimdall Zone plunges shallowly to the northeast, starting from surface. Within this broad zone, high grade quartz-vein-hosted mineralization form veins and/or lenses which are currently correlated between drillholes over distances up to 100m. An example of such veins is shown with core photos in Figure 1. Figure 2 shows a plan map of the drilling completed to date, while Figure 3 shows the correlation of these intercepts on a longitudinal section looking at the Zone from underground.

The primary host rock for mineralization identified to date is a thick sequence of highly altered and often brecciated dolostone of the Cambro-Ordovician Saint George Group. Mineralization encountered to date typically consists of tetrahedrite-tennantite, chalcocite, sphalerite, galena, pyrite, and potentially additional sulfosalt minerals. Quartz veining and associated mineralization are ubiquitous throughout the dolostone unit, but included metallic mineralization is best developed in areas of combined brecciation and veining, especially towards the western contact of the host dolostone unit and an underlying argillite sequence. The structural evolution and metallogenic sequencing are very complex, and mineralization has been identified in association with a multitude of structural events.

Sterling hired SRK Consulting of Toronto, ON, to conduct a detailed structural study of outcrops and drill core. The results of this study have been incorporated in Sterling’s targeting model and will be utilized for the 2022 program.

Sterling also continues to utilize the geological modelling and machine learning tools from Goldspot Discoveries Corp., who are also a significant shareholder of the Company. Using the IP and gravity surveys, along with the results from this last summer’s drill program, Goldspot has been able to highlight the exploration areas along the 12km trend line seen in Figure 4.

Kelly Malcolm, Technical Advisor to Sterling, commented “We are very pleased to have identified a clear body of mineralization on the first ever drilling program at Sail Pond. The Heimdall Zone is showing substantial strike length & width, along with a strong background of silver and base metal mineralization. The higher-grade vein-hosted mineralization within the lower grade zones are starting to show correlation between holes and we are excited to continue to advance and grow the Zone. On the regional exploration front, the identified flexure at the contact of the host dolostone and the footwall argillite that has a control on the size of the mineralized system at Heimdall has generated a number of targets in both the north and south zones that have never seen any drilling. In addition to continued expansion and definition of the new Heimdall Zone announced today, Sterling will drill test each of the additional structural features that have been identified through geophysics, prospecting, and geochemical surveys. The Company is planning its 2022 exploration program and expects to be back on the ground towards the end of the Spring.”

Silver Equivalent Calculation Silver equivalent (Ag Eq) values were calculated using the following formula: ((Ag_oz*$USAg_price/oz)+(Au_oz*$USAu_price/oz)+(Cu_lb*$USCu_price/lb)+(Pb_lb*$USPb price/lb)+(Sb lb*$USSb_price/lb)+(Zn_lb*$USZn_price/lb))/$USAg_price/oz.

Silver equivalent grade calculations are based on the current spot metal prices and are provided for comparative purposes only. This approach reflects the polymetallic nature of the mineralization. Recovery factors of 100% have been assumed for all metals. Metallurgical tests will be required to establish recovery levels for each element reported. Metal spot prices as at the close of the London Metals Exchange February 3rd 2022 were applied and include: Ag – $US 22.37/oz; Au – $US1803.60/oz, Cu – $US4.44/lb; Zn – $US1.62/lb; Pb – $US 0.99/lb. The Sb – $US 5.45/lb price applied was sourced from Argus Media, a recognized provider of energy and commodity price benchmarks.

Laboratory Technical Note Analytical services were provided by Eastern Analytical Limited (Eastern) of Springdale Newfoundland, which is an independent, CALA-accredited analytical services firm registered to ISO 17025 standard. Drill core was halved by sawing at the Sterling core facility and half-core samples were securely stored at the facility until being delivered to Eastern by commercial transport. Samples were crushed to 80% passing 10 mesh, split to 250g, and pulverized to 95% passing 150 mesh. Au assays were conducted on 30g of pulverized material using the Fire Assay method with an AA finish. Multi-element analyses, including base metals, were conducted on pulverized material using the ICP method for 34 elements. Laboratory over-limits analysis methods were applied as required. A systematic QAQC protocol was employed that includes systematic insertion in the sample stream of certified reference materials and blank samples, plus analysis of duplicate pulp splits.
