Sun Metals Provides Update on Stardust Exploration Program

VANCOUVER, July 23, 2019 /CNW/ - Sun Metals Corp. ("Sun Metals" or the "Company") (TSXV: SUNM) reports on progress from the current exploration program at its 100% owned Stardust project in northcentral British Columbia.  The 2019 program consists of diamond drilling, along with surface electromagnetic (EM) and borehole electromagnetic geophysical surveys (BHEM) and continued geological studies with a budget of $5.4 million.

Diamond drilling was initiated in late May with two drills.  To date, the drills have completed 3,671 metres over nine drill holes in four pilot holes, and drill holes ten and eleven are in progress. The primary focus of the diamond drill program is to explore around the mineralization identified in drill hole DDH18-SD-421 (see press release at https://sunmetals.ca/news/2018/) which returned a 100.00 metre interval of 2.51% copper, 3.03 grams per tonne (g/t) gold, and 52.5 g/t silver for a  4.99% copper equivalent^(1,2).  Diamond drilling to date has tested areas on section with DDH18-SD-421 and areas to the south where a BHEM survey completed at the end of the 2018 program identified an EM conductor.

Directional diamond drilling has been used in all of the 2019 drilling at Stardust to increase the precision and accuracy of drilling step-outs. Another benefit of this style of drilling is the use of pilot holes which has resulted in a 35% reduction in metres drilled. The Stardust team is also using oriented core to assist Sun Metals' geologists in advancing their knowledge of the structural characteristics of the local rocks. 

A total of 1,527 samples have been selected from the nine completed holes and 1,264 samples have been shipped to the Bureau Veritas laboratory in Richmond, BC. A full suite of QA/QC samples are included in the sampling process, including standards, blanks, field duplicated and laboratory duplicates. Bureau Veritas is a fully certified and internationally recognized facility.

In conjunction with the diamond drilling, large loop ground EM surveys are being conducted along strike of the phyllite/carbonate contact in the Canyon Creek skarn zone. A large loop grid has been completed over the Canyon Creek skarn zone with 25.3 line km of surveying completed and the crew is now working in the area to the south. BHEM surveys have also been conducted on five holes in this program. 

Technical aspects of this news release have been reviewed and approved by Ian Neill P.Geo., Vice President Exploration of Sun Metals, who is a qualified person as defined by National Instrument 43-101.

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 (joint-ventured with Teck Resources Limited), and the OK copper-molybdenum project. 

The Canyon Creek copper-gold skarn zone at Stardust was the subject of a 2018, 43-101 compliant resource estimate published by the Company in January 2018. GeoSim Services Inc. provided the following estimate.

Stardust Project - Canyon Creek zone Mineral Resource Estimate⁽¹⁾:

Resource Category	Tonnes	Copper %	Zinc %	Gold g/t	Silver g/t	% Cu Eq
Indicated	985,000	1.34	0.62	1.59	36.8	2.92
Inferred	1,985,000	1.24	0.14	1.72	30.5	2.65

⁽¹⁾The cut-off grade used in the resource estimate was 1.5% copper equivalent (Cu Eq). Metal price assumptions for the Cu Eq calculation were $3.00/lb Copper, $1.25/lb Zinc, $1,300/oz Gold and $18/oz Silver. Adjustment factors to account for differences in relative metallurgical recoveries of the constituents will depend upon completion of definitive metallurgical testing. The following equation was used to calculate copper equivalence: Cu Eq = Copper + (Zinc x 0.4167) + (Gold x 0.6319) + (Silver x 0.0087). A cut-off grade of 1.5% Cu Eq represents an in-situ metal value of approximately $100/tonne which is believed to represent a reasonable break-even cost for underground mining and processing. These are not mineral reserves and no work has been completed that demonstrates economic viability at the Project.

⁽²⁾ True widths of the reported mineralized intervals have not been determined

Sun Metals believes B.C. is a reliable jurisdiction with excellent exposure to capital markets, a deep pool of exploration professionals, a wealth of supporting services, and exceptional infrastructure with direct access to Pacific markets.
