News Releases

Vancouver, B.C. – Sun Metals Corp. (“Sun Metals” or the “Company”) (TSXV: SUNM) reports that drilling shows extension of high-grade copper-gold mineralization in the 421 zone. The zone is open in several directions but notably extends up plunge into an area that is closer to surface, toward the previously known Canyon Creek zone. The 421 zone is located at the Company’s 100% owned Stardust project in northcentral British Columbia. Highlights from the 2019 program include:

  • 15 pierce points now define the 421 zone and have established continuity.
  • 421 zone of high-grade copper-gold mineralization has been followed along a plunge length of 325 metres and remains open for extension.
  • Average mineralized drill intercepts in the 421 zone are greater than historic drill intercepts in the Canyon Creek zone1 (See Table 2).
  • Reported mineralized intercepts in 2019 range from 3 to 142 metres2 (See Table 2).
  • Over 60% of drill holes in 2019 intersected reportable length and grade of sulphide mineralization2.
  • Drilling has proven that high-grade copper-gold mineralization continues up plunge to the south and shows significant potential for extension of the 421 zone in that direction.

The 421 zone was a raw discovery in late 2018 and has now evolved into one of the mining industry’s most significant high-grade copper-gold exploration projects. The Stardust project hosts this discovery in a Tier 1 jurisdiction with exceptional access to infrastructure.  

Drilling Results

Highlights from the newly reported results include a step to the south in drill hole DDH19-SD-453M which returned 26.30 metres grading 1.45% copper, 1.48 gram per tonne (g/t) gold and 22.2 g/t silver, or 2.59% copper equivalent (CuEq)4. A second interval in the same hole returned 7.20 metres of 2.10% copper, 1.41 g/t gold and 33.4 g/t silver or 3.29% CuEq. These mineralized intervals are believed to be an offset extension of the 421 zone mineralization up plunge and to the south, on the south side of a splay of the Canyon Creek Fault. This is the most southerly test of the 421 zone to date indicating shallower mineralization remains open in this direction.

2 See full drill results table available at www.sunmetals.ca.

The southern extension of the 421 zone establishes a closer spatial link to the historic Canyon Creek zone with drill hole DDH19-SD-453M only 130 metres away from historic drill hole 2002-09 (historically reported as 2.19% copper, 24.0 g/t gold and 134.3 g/t silver over 15.00 metres) which has previously been considered the down-plunge limit of the Canyon Creek zone (see Figure 2).

Drill holes DDH19-SD-443D and DDH19-SD-444D represent step-outs down plunge and to the north on sections 2150N and 2200N respectively (see figures 3 and 4). These new intervals have revealed a lower extension of the 421 zone mineralization envelope and are still open to depth.

The two most northerly fences of drilling on sections 2275N and 2375N did not intersect significant intervals of sulphide mineralization implying that there is a faulted down drop in the area. Samples collected from drill holes DDH19-SD-452D and DDH19-SD-454D are still pending at the time of this release, however visual inspection and logging of the drill core does not indicate that significant material intersections are expected.

(3) True widths of the reported mineralized intervals have not been determined
(4) Assumptions used in USD for the copper equivalent calculation were metal prices of $3.00/lb. Copper, $1,300/oz Gold, $18/oz Silver, $1.25/lb. Zinc and recovery is assumed to be 100% as no metallurgical test data is available. The following equation was used to calculate copper equivalence: CuEq = Copper (%) + (Gold (g/t) x 0.6319) + (Silver (g/t) x 0.0087) + (Zinc (%) x 0.4167). The following equation was used to calculate gold equivalence: AuEq = (Copper (%) x 1.5824 + Gold (g/t) + (Silver (g/t) x 0.01385) + (Zinc (%) x 0.6593).

Review of 2019 Exploration of the 421 zone 

The discovery of the 421 zone at the Stardust project in northcentral British Columbia in late 2018 was a watershed moment for Sun Metals. The initial 100 metre intercept of 5.05% CuEq4  in drill hole DDH18-SD-421 was a significant increase from the historic average intercept of 4.3 metres within the previously defined resource on the property1. This prompted the Company to consolidate ownership by acquiring the project owner, Lorraine Copper Corp. The transaction was successfully completed on April 12, 2019 (see press release dated April 12, 2019) resulting in Sun Metals owning 100% of the Stardust project with no underlying royalty or other encumbrances.

The 2019 Stardust field program began in May with two drills dedicated to delineation and exploration of the new zone of semi-massive and massive sulphide mineralization. A third drill was added late in the season, with the field program continuing through to December 20th. In 2019, the Company drilled 14,066 metres in 7 pilot holes and 28 daughter holes. Due to the depth of the north plunging mineralization, directional diamond drilling was utilized to increase the effectiveness of drilling, both by reducing the amount of metres required to drill from surface, and through the ability to steer holes at depth, directly into target areas. This drilling method, which employs the use of pilot and daughter holes, resulted in a 34% savings in the metreage that would have otherwise been needed to drill the same targets from surface.

The average mineralized drill intercept length in the 421 zone is greater than historic drill intercepts in the Canyon Creek zone. With the most recently published results in this release, the plunge length of the 421 zone is now established to be 325 metres. The 421 zone is already one of the most  significant recent high-grade copper-gold discoveries in British Columbia. The extension to the south brings the known mineralization closer to the Canyon Creek zone and there may be significant synergy in being able to establish a connection of the two zones. This may have positive future implications for the style of mining that may be possible.

Planning for 2020

The 2019 field program was completed on December 20th. It was a very productive year for the Company and the exploration team will take the time to fully assess the data gathered in 2019 and plan a full program for 2020. Sun Metals has ended 2019 with approximately $3.8 million flow through dollars that is budgeted toward the upcoming 2020 program. 

Details on the timing, quantum and form of field activities in 2020 will be announced when the planning process has been completed. 

Graphics & Table

Updated graphics including a plan map of the 2019 drill program (Figure 1), cross sections 2050N, 2150N, 2200N, 2275N, 2325N and a 421 zone vertical section (Figures 2-7), and a full table of reported results to date from the 2019 drill program (Drill Results Table) are available on the Company website3:

Geophysics

Borehole Electromagnetic (BHEM) geophysical surveys were conducted on 17 of the 28 drill holes during the season using SJ Geophysics Volterra system.  The surveys provide valuable information by detecting mineralization proximal to drill holes which might not be present in the drill hole.  This data can be used to guide future drilling.  In addition, 71.85 line km of large loop Time Doman Electromagnetics (TDEM) was completed on surface.  The surveys cover the entire strike length of the carbonate package associated with the 421 zone and will be used to target areas of additional mineralization.  In addition, two lines of magnetotellurics were completed, one North-South and one East-West across the zone for a total of 6.2 line kilometres.  Full Interpretation and modelling of the survey results is ongoing.

Infrastructure

In order to extend the field program into winter, the Stardust camp was expanded to a 40 worker capacity and upgraded for all season use. At the work site, a new 4.1 km long access road was constructed from the valley bottom to the current work area allowing safer all-season access.

Environmental Baseline

An automated hydrometric station was installed downstream of the mineralized area to facilitate collection of high-quality water discharge data from the area. A broad water quality sampling program, initiated in 2018, continued through the 2019 field season to characterize the baseline water quality data in the area.  Installation of an all-season weather station was initiated to collect detailed meteorological data. All instrumentation will provide the quality of data that will be expected by Engineers and government agencies for any potential engineering or permitting that the Company may wish to undertake in future.   This work was completed in cooperation and coordination with Takla First Nation.

Metallurgy

Metallurgical samples have been gathered from the 2019 diamond drilling in the 421 zone and sent for initial testing. The goal will be to determine optimal grind size, predicted metal recoveries and metal concentrate characteristics. Work index will also be calculated from this sample. Results are expected in early Q2.

About British Columbia

British Columbia is highly regarded as a Tier 1 jurisdiction where citizen enjoy the advantages of political stability, strong rule of law, a highly skilled and experienced workforce, world class electrical grid and seaports, a stable fiscal regime, an established predictable regulatory environment and strong governmental supportive programs. This is further enhanced by the tremendous geologic endowment of the area as evidenced by the large number of former and current mines.

Quality Assurance / Quality Control

Drilling completed on the project in 2019 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.

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, 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.

(5) The cut-off grade used in the resource estimate was 1.5% copper equivalent (Cu Eq). Metal price assumptions for the Cu Eq calculation in this table 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.

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