Acquisition: Etruscus staked the Sugar Property in early 2019 as part of a strategic land staking program which included the expansion of the Rock & Roll Property towards the northwest.
Overview: The Sugar Property is located within BC’s Golden Triangle, 25 km southwest of the Galore Creek deposit and 7 km northwest of the Rock and Roll Property. Past mapping on the property has outlined multiple Texas Creek intrusive units that are commonly associated with important copper and/or gold deposits within the Golden Triangle including Galore Creek, KSM copper-gold deposit and Pretium’s Brucejack (Valley of the Kings) gold deposit.
Location and Access
Etruscus’ wholly owned Sugar Property covers 4,508 hectares to the east of the Stikine River Valley of northwestern British Columbia-165 km north of the ocean port at Stewart. The property is situated within the Golden Triangle which has produced enormous precious and base metal wealth over the past century. This area also contains billions of dollars of undiscovered gold, silver, and copper that sit within unexplored areas.
Once seen as remote, British Columbia’s Golden Triangle has opened up dramatically, with two mines now in production, three new hydro-power facilities, a link to the provincial power grid, and roads throughout the region. Now these world-class deposits can be finally tapped because of infrastructure developments including:
Completion of a $700 million high-voltage transmission line to the Golden Triangle. The Northwest Transmission Line goes 335km from Terrace to Bob Quinn Lake, and north to the Red Chris mine. The power line to the region was a game-changer in terms of project economics, bringing in electricity that is near the lowest cost in the world.
The Sugar Property itself covers 10 contiguous MTO claims located on the east side of the Stikine River Valley.
Access to the property is made via helicopter from the Forest Kerr hydroelectric facility 35 km away. However, 2019 has seen Seabridge Gold Corp propose a road extension from the existing Forest Kerr road to the Bronson Camp located 7 km away from the Rock and Roll property which would improve access to the Sugar Property dramatically.
Historical Work: Exploration activity within this region has been limited due to its remote location. During the 1950’s regional copper exploration became prominent with the discovery of Galore Creek. During the 1980’s another increase of regional exploration took place after the discovery of the Snip mine as well as Johnny Mountain. The first recorded exploration activity on the Sugar Property was undertaken by the British Columbia Ministry of Energy, Mines and Resources in completing a large scale stream sediment sampling program throughout the region. This led to the staking of the original Sugar claims in 1987 by Lacana Exploration Inc a subsidiary of Corona Corporation. The two years that followed saw mapping and sampling occur from fly camps located across the property. A total of 524 rock samples were collected by Lacana focusing on multiple showings that included magnetite zinc skarn showings as well as porphyry style quartz veining hosting chalcopyrite and pyrite (Jones, 1989).
In 2014 Coast Mountain Geological Ltd did a one-day reconnaissance on behalf of Hydro Capital Corp. A total of 15 rock samples were taken focusing on the high–grade copper and zinc showings in the north central portion of the property.
The large land package remains under-explored with no drilling ever done on the Sugar claims. Historic rock samples have returned numerous results greater than 1% copper and 5% zinc spread over a large portion of the property.
The Golden Triangle region of Northwestern British Columbia is one of the most richly mineralized areas in the world. The tally of total gold ounces in the Golden Triangle only represents half of the contained metal value since the region also hosts an equivalent value in silver, copper, lead, zinc and other metals. Although the Golden Triangle is dominated by large porphyry copper-gold deposits, the region also hosts a variety of other deposit types. For example, Eskay Creek, a volcanogenic massive sulphide (VMS) deposit, produced 3 million ounces of gold and 160 million ounces of silver from ore with a spectacular grade of 49 g/t gold and 2,406 g/t silver. That deposit was so rich that Barrick transported the untreated ore to a smelter in the United States.
The Sugar Property sits on the edge of the Intermontane belt where it adjoins the coast mountain plutonic complex to the West. Metasedimentary rocks of the Stikine assemblage are overlain by felsic and intermediate volcanics as well as sediments of the Stuhini formation. Late Jurassic Texas Creek intrusions have been mapped across the property intruding into the Stuhini and Stikine assembalges. These intrusions have the significance of hosting many of the major porphyry deposits within the Golden Triangle. Eocene granitoid intrusions relating to the coast plutonic complex also intrude the stratigraphy.
Mineralization across the Sugar claims has been broken into multiple showings with potential for multiple mineralizing systems. Examples of Skarn (chalcopyrite, magnetite, zinc) have been shown to outcrop along a 4 km trend. Other examples of stockwork and quartz veining are host to disseminated and blebby chalcopyrite and pyrite. The scale of mineralization along multiple km’s speaks to the potential for a nearby porphyry intrusion.
2019 Work Program
In summer of 2019, Etruscus Resources completed a field program of mapping, sampling and prospecting on the sugar claim. A total of 20 rock samples were taken on the property. Sites visited were based on historic geochemical anomalies spread across an 8 km trend of anomalous copper. Skarn mineralization containing magnetite, chalcopyrite and sphalerite was identified on the property and a 1 km gossanous trend was outlined along a prospective 4 km limestone horizon. Samples at this location revealed highs of 3.63% zinc, 1190 ppm copper.
Texas Creek Plutonic Suite Rocks were also identified on the Sugar. These rocks are the metallurgical source for many large mineral deposits in the area such as KSM, Brucejack, Red Chris and Johnny Mountain. They are mapped adjacent to the skarn showings and are highly prospective for locating copper gold porphyry deposits.
Mapping also identified 2 quartz veins during exploration work. A grab sample taken from a newly identified quartz/chalcopyrite vein measuring 25 m in strike length assayed 8210 ppm copper. This new showing occurs in an area of large glacial retreat with consistent copper mineralization projecting towards 2 of the shrinking glaciers. Historic stream sediment samples taken from Fowler Creek that drains these 2 glaciers are the most anomalous across the property. The second quartz vein had a strike length of nearly 100 m and occur in a broad area of hornfelsing, often associated with upper porphyry systems. Large-scale copper porphyry targets are possible at both these locations.
Based on the large scale geochemical anomalies found across the property a large field program will be initiated in 2020. Detailed mapping will take place at all the main historic showings. Prospecting will take place along the toe of the glaciers to assess new unexplored ground. Geophysical tools will likely be used to help vector into future drill targets as the Sugar becomes an attractive property for discovery as infrastructure moves closer and closer.
The ongoing goal for the Sugar property is to advance all the current mineralized showings into a more cohesive geological model that could lead to a large copper porphyry target similar to Seabridge’s KSM deposit or Teck/Newmont’s Galore Creek Deposit.
