Sun Metals Reports More High-Grade Results at Stardust Intersecting 3.40% Cu Equivalent Over 17.45 m Grading 1.37% Cu, 1.70 G/t Gold and 39.7 G/t Silver

Drill hole DDH20-SD-466 was drilled into an area near historic drill hole LD2002-09 which was significantly enriched in gold relative to copper (Figures 2 and 3). The mineralization returned was more conventional regarding metals ratios with similar value in copper and gold, but remains a strong high-grade intercept in an area that is much closer to surface than other recently reported intercepts. The hole intercepted:

"As we explore the detailed nature of the Stardust mineralized system, the thickness and grade of the intercepts continue to impress. However, equally impressive is the strength of the hydrothermal system driving it. For instance, drill hole DDH20-SD-463 returned 78.15 m of 0.28% CuEq from a 150 m zone of hydrothermal alteration. The drill hole targeted a significant step out, below a lens in the Canyon Creek zone and provided some valuable insight into the larger-scale plumbing system that contains the higher-grade mineralization. Additional work will be needed to zero in on the high-grade in this area but we know the environment is ripe for a massive sulphide with all of the hydrothermal preparation in the area." states Sun Metals President & CEO Steve Robertson.

Other Drill holes
DDH20-SD-461M tested for a southern extension of the 421 zone. The hole intersected a 170 m interval of hydrothermal alteration along the mineralized trend. Drilling intercepted 22.10m of lower grade mineralization in the projected lower extension of two lenses of the Canyon Creek zone, with one section returning 1.72% CuEq over 5.05m. The hole intersected numerous porphyritic quartz diorite intervals at the projected intersection depth of the 421 zone, suggesting that some of the mineralization may have been displaced.

DDH20-SD-462 was drilled into a fold target to the east of the 421 zone. The target for this hole was the projected hinge zone of folded limestone, prospective for hosting additional 421 style mineralization. The hole intersected limestone at a depth of 610m with hydrothermal alteration and a small base and precious metal vein containing elevated zinc, lead and silver. The Sun Metals exploration team was encouraged to see that the fold was subjected to hydrothermal fluids carrying base and precious metals, making this area a target for further exploration.

DDH20-SD-463 was drilled below the Canyon Creek zone where mineralization remains open at depth. The hole intersected a 150m interval of elevated base and precious metal values within altered sedimentary and intrusive rocks that typically form the hanging wall of the zone. The hole then intersected a deeper interval of mineralization grading 1.04 CuEq over 9.60m (0.58% Cu, 0.36 g/t Au, 11.0 g/t Ag) from 823.80m. This interval does not correlate well to any known zones and may represent an additional mineralized pathway (Figures 2 and 4).

Quality Assurance / Quality Control
Drilling completed on the project in 2020 was supervised by on–site Sun Metals personnel who collected and tracked samples and implemented a full QA/QC program using blanks, standards and duplicates to monitor analytical accuracy and precision. The samples were sealed on site and shipped to Bureau Veritas (BV) in Vancouver BC for analysis. BV's quality control system complies with global certifications for Quality ISO9001:2008. Core samples were analyzed using a combination of BV's AQ270 process for low level concentrations (ICP–ES/MS aqua regia) and the MA270 process for higher level concentrations (ICPES/MS 4 acid digestion). Gold assaying was completed with FA330, a 30–gram fire assay with ICP–ES finish. Base metal overlimits were finalized with titration, with gold overlimits completed with a gravimetric finish. A silica wash was used between high–grade samples to ensure no sample carry over.

A total of 11,988m of drilling was completed in 17 drill holes with 3,147 samples shipped to the lab. Lab turnaround time has been significantly negatively impacted by the COVID-19 pandemic and consequently, results from ten drill holes have been received at the time of this release. Additional results from the program will be reported when they are received from the lab.

Prices used to calculate the CuEq values¹ in this project have been updated from previous reporting on the Stardust project to reflect the change in commodity prices.

About Sun Metals
Sun Metals is advancing its 100% owned flagship, high-grade Stardust Project located in northcentral British Columbia, Canada. Stardust is a high-grade polymetallic Carbonate Replacement Deposit with a rich history. Sun Metals also owns the Lorraine copper-gold project, and the OK copper-molybdenum project.

The Canyon Creek copper-gold skarn zone at Stardust was the subject of a 2018, NI 43-101 resource estimate published by the Company titled "Stardust Project NI 43-101 Technical Report Omineca Mining Division, British Columbia" with an effective date of January 8, 2018. In that report, GeoSim Services Inc. provided the following estimate.
