INTERSECTS 100 METRES GRADING 5% COPPER EQUIVALENT IN DRILL HOLE AT STARDUST PROJECT
The full mineralized intersection from diamond drill hole DDH18-SD-421 at Sun Metals Corp.'s (SUNM.V) Stardust project in north-central British Columbia has now been completely assayed and has returned a total 100-metre intersection grading 2.51 per cent copper, 3.03 grams per tonne (g/t) gold and 52.5 g/t silver for a 4.99 per cent copper equivalent (CuEq).
The completed results from DDH18-SD-421 reinforce that drilling has intersected consistently stronger and more pervasive mineralization than historically encountered at Stardust by previous operators. The results further validate the Company is successfully tracking a major mineralizing fluid pathway toward the heart of this high-grade system.
New results include 29.1 metres of mineralization, grading 3.35% copper, 4.29 g/t gold and 65.7 g/t silver (See Table 1 and Figure 2). This intersect is downhole from Stardust's previously reported best ever intercept, (see press release at https://sunmetals.ca/news/2018/ ). The 100-metre intersect also includes 22.8 metres of mineralized skarn alteration in the hanging wall of the massive sulphide that averages more than 1% copper equivalent. The mineralized interval in drill hole DDH18-SD-421 is in a newly identified mineralized area, outside of the current 43-101 resource estimate. See detail on the resource estimate at the end of this news release. Mineralization in this Canyon Creek Skarn zone extension remains open in all directions (See Figure 3).
The Company believes this drilling has revealed the distinct pattern of encountering larger bodies of more persistent and higher-grade mineralization closer to the source of the mineralizing fluids that formed the skarn system.

(1) Assumptions used in USD for the copper equivalent calculation were metal prices of $2.80/lb Cu, $1,200/oz Au, $15/oz Ag, $1.20/lb Zn and recovery is assumed to be 100% as no metallurgical data is available. The following equation was used to calculate copper equivalence: Copper Equivalent = Cu (%) + (Au (g/t) x 0.6252) + (Ag (g/t) x 0.007815) + (Zn (%) x 0.4286).

Further results for an additional 14 drill holes from the 2018 program are pending and are expected to be available for release by year end.
