SUN SUMMIT DEFINES HIGH PRIORITY AU-AG TARGETS AT THE FINN ZONE, JD PROJECT IN THE TOODOGGONE DISTRICT, NORTH-CENTRAL B.C.
Sun Summit Minerals Corp. has identified high-priority gold and silver drill targets at the Finn zone, central to the recently optioned JD project in the Toodoggone gold-copper mining district in north-central British Columbia.
- Significant data compilation has defined priority targets: A continuing comprehensive review and compilation of property-wide historical data has resulted in the definition of multiple new target areas, including mineralization expansion potential within the Finn zone.
- High-grade gold and silver mineralization in historical drill holes at Finn: Results from historical drilling highlight the high-grade gold-silver potential of near-surface epithermal-related mineralization at the Finn zone. Select drill highlights* include:
- 35.7 metres of 7.26 grams per tonne Au, including one m of 215.4 g/t Au (JD95-047);
- 22 m of 12.5 g/t Au, including 0.8 m of 171.5 g/t Au (JD95-064);
- 25.9 m of 6.42 g/t Au, including 6.1 m of 12.8 g/t Au (JD94-015);
- 22 m of 6.32 g/t Au, including 12.6 m of 10.8 g/t Au (JD12-003);
- 27.8 m of 6.64 g/t Au, including 11 m of 15.1 g/t Au (JD95-097).
- Multiple target areas defined for follow-up drill testing: The footprint of mineralization at the Finn zone remains open in most directions, and historical data review identified numerous priority areas for initial drill testing to better define the extent of mineralization along strike, down dip and at depth. In addition, many historical drill holes were selectively sampled and the current data review suggests that many of these unsampled areas were in prospective geology.
*Note drill intervals are downhole core lengths. True widths are unknown.
"We are very excited to have commenced the compilation and review of historical exploration data from across the JD project area as a means of identifying high-priority targets within the project, and specifically at the Finn and Creek zones," stated Sharyn Alexander, Sun Summit's president. "This data compilation is the first of its kind for the project, and is a critical component to ongoing target generation and prioritization. The extensive historical data, dating back to the 1970s, will provide invaluable insights into the ongoing exploration potential of the project and lead to boots-on-ground exploration work, expected to commence in late May of this year. As the data compilation and review process progresses, we'll continue to report on additional target areas as they emerge."
JD project overview
The JD project comprises over 15,000 hectares of contiguous mineral claims in the prolific Toodoggone gold-copper mining district in north-central British Columbia. The project is host to high-grade epithermal-related gold-silver systems and porphyry-related copper-gold systems.
The company is currently compiling, digitizing and interpreting all historical exploration data collected since the early 1970s and reported in over 70 public assessment reports. This data compilation will represent a critical component to continuing target selection and prioritization. Exploration data include approximately 16,000 soil samples, 2,000 rock samples, 130 trenches, over 330 drill holes, and numerous ground- and airborne-based geophysical data sets.
Most of the historical drilling at the JD project was focused on the Finn target where a broad zone of near-surface, epithermal-related gold-silver mineralization has been defined. Mineralization is primarily hosted in the hangingwall of a gently north-dipping, northeast-striking, inferred reverse fault. The fault, traced for over 1.5 kilometres along strike to the west from the Finn zone, separates two andesite-dominant lithological units of the Toodoggone formation (Metsantan and McClair members). Faulting and subsequent mineralization likely exploited a volcaniclastic unit, at the base the Metsantan member, where epithermal-related fluids were focused along permeable volcanic breccias.
The core of the Finn zone consists of strongly silica plus clay plus sericite altered polymictic breccias, locally cemented with quartz and mineralized with pyrite with lesser sphalerite, galena and chalcopyrite. Peripheral to the high-grade core, epithermal-related alteration grades into sericite plus chlorite plus pyrite and more distal epidote plus chlorite plus/minus hematite assemblages.
Most of the drilling from the 1990s at the Finn zone targeted the higher-grade core covering a footprint of approximately 300 metres by 100 metres within which drill holes were mostly collared on 25-metre centres. Although drilling, logging and surveying methods were completed to industry standards, core sampling was locally selective and left significant gaps in sampling. Some drill holes ended in Au-Ag mineralization and were not followed up with additional drilling. More recent drilling in 2012 and 2013 tested the margins of the Finn zone and extended the zone of mineralization down dip for 350 metres and along strike for 500 metres.
Based on this review of historical drilling at the Finn zone, numerous priority areas for initial drill testing have been defined. These include:
- Infill drilling near the centre of the high-grade core to verify historical grades, confirm structural controls while drilling deeper to investigate the geometry and grade of the locally strongly mineralized footwall zone (such as JD12-009);
- Stepout drilling down dip toward hole JD12-015 to investigate mineralization continuity and to explore for additional higher-grade zones;
- Stepout drilling along strike toward hole JD13-024 to systematically test the low-angle fault zone for additional Finn-zone-style high-grade gold-silver mineralization.
Data compilation is continuing and additional target areas will be reported as the process continues.
National Instrument 43-101 disclosure
This news release has been reviewed and approved by Sun Summit's vice-president, exploration, Ken MacDonald, PGeo, a qualified person as defined in National Instrument 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators. He has not been able to verify the historical exploration data disclosed, including sampling, analytical and test data, underlying the technical information in this news release since such data are historical and the original drill core is not readily available. Technical information contained in this release is historical in nature and has been compiled from public sources believed to be accurate. The technical information has not been verified by Sun Summit and may in some instances be unverifiable dependent on the existence of historical drill core and grab samples.
Sun Summit is engaging with first nations on whose territory the company's projects are located and is discussing their interests and identifying contract and work opportunities, as well as opportunities to support community initiatives. The company looks forward to continuing to work with local and regional first nations with continuing exploration.
About the JD project
The JD project is located in the Toodoggone mining district in north-central British Columbia, a highly prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in close proximity to active exploration and development projects, such as Thesis Gold's Lawyers and Ranch projects, TDG Gold's Baker-Shasta projects, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open-pit copper-gold mine.
The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres north of the Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess mine, including roads and a hydroelectric power line.
The JD project is in a favourable geological environment characterized by both high-grade epithermal gold and silver mineralization, as well as porphyry-related copper and gold mineralization. Some historic exploration, including drilling, geochemistry and geophysics, has been carried out on the property; however, the project area is largely underexplored.
