- 2019 field work adding to the geologic understanding of the area and highlighting several potential new targets.
A prolific number of mineral occurrences and similar geology to many world-class deposits in the area suggests a large district scale mineralizing system and the potential opportunity for discovery of a major deposit within the Surprise Creek property.
The property is part of the mineral-rich Stikine Arch lying along the eastern flank of the Coast Mountains. The Stikine arch consists of a series of Late Triassic to Jurassic oceanic arc volcano-sedimentary rocks that have been accreted onto ancestral North American in the Cretaceous. It is host to many important mineralized deposits in British Columbia including porphyry, epithermal and VHMS deposit types.
The historic high-grade silver Goat Mine borders the property to the south. Exploration by multiple companies over the last 30 years has identified numerous silver-gold-base metal occurrences on the property.
The Surprise Creek and the BA properties are underlain by Lower Jurassic sub-marine and sub-aerial volcanic, epiclastic and clastic rocks belonging to the Upper and Lower Hazelton Group. The Lower Hazelton consists of predominately green and maroon volcanic and volcaniclastics of andesitic composition. This is intruded and overlain by more felsic volcanic and minor clastics that have been referred to as the Mount Dilworth formation. The Upper Hazelton unconformably overlies the Lower Hazelton and consists of predominately clastic rocks.
Mineralization occurs throughout the Hazelton Group rocks however the most prospective areas appear to be associated with the more felsic volcanic units and sediments at the top or the Lower Hazelton.
Volcanogenic massive sulphide horizons and related feeder zones have been identified on the property and consist of pyrite, sphalerite, galena, chalcopyrite in a gangue of quartz, carbonate and barite. Significant silver and gold values occur with the sulphide. Mineralization has been traced along a north trending zone for eight kilometres extending from the historic Goat Mine in the south, through the Grundwald and Ataman showings and the newly discovered showings located on the next two ridges to the north.
The showings are believed to be hosted in the same package of rocks as the historic Eskay Creek deposit located 70 kilometres to the northwest. Eskay Creek was an exceptionally high-grade precious metal VHMS deposit that produced 2.18 million tonnes of ore with an average grade of 46 g/tonne gold and 2,267 g/tonne silver (BC Geological Survey 2008). The contact between the Salmon River Formation and the underlying Mount Dilworth Formation has been mapped on the MTB property.
OWENERSHIP:Mountain Boy Minerals Ltd and Great Bear Resources Ltd (GBR) each own a 50 % interest in the BA claims. Mountain Boy is in the process of purchasing GBR’s 50% interest to regain a 100% interest in the project
LOCATION: 32 kilometres northeast of Stewartlocated in the “Golden Triangle” area within the Skeena Mining Division of British Columbia.
INFRASTUCTURE: 3 kilometres north of highway 37A and the Stewart high-voltage transmission line; 12 kilometre 4×4 road to the southeast corner of the property from highway 37A.
PRIOR WORK: The first recorded work was in 1989 when The SURP claims were acquired by Teuton Resources. Teuton conducted reconnaissance prospecting, geological mapping and soil, stream sediment silt and rock sampling between 1990 and 1996.
From 2003 to 2007,Pinnacle Mines held several exploration campaigns that included the collection of over 600 rock samples from outcrop and float. The work defined multiple areas that hosted polymetallic mineralization with assays up to 13.02 grams per tonne gold, 3,076.8 grams per tonne silver, 8.67% copper, 9.1% lead and 7.61% per cent zinc. In 2006, Pinnacle focused on the west part of the property where they mapped a large zone of intense pervasive K-feldspar alteration. In 2007, four holes were drilled on the property, totaling 1995 metres. The drilling intersected some zones of mineralization, the best being as follows;
- 52 metres of 84.2 grams per tonne silver, 0.36% copper, 0.07% lead and 0.04% zinc
- 59 metres of 45.9 grams per tonne silver, 0.095% copper, 0.14% lead and 0.24% zinc
- 07 metres of 75.7 grams per tonne silver, 0.069% copper, 1.09% lead and 0.22% zinc.
In 2010, Great Bear Resources contracted Geotech to conduct a helicopter-borne versatile time domain electromagnetic (VTEM) and aeromagnetic geophysical survey over the property. A prospecting, geological mapping and sampling program was also conducted resulting in the discovery of the Ataman zone which at the time was referred to as the Rumble zone. Assays of up to 68.5 grams per tonne silver, 3.85% lead and 2.28% zinc were returned from the Ataman zone.
Mountain Boy Minerals conducted exploration programs in 2016 and 2017. In 2016, work was focused on the Ataman Zone. A total of 218 rock samples were collected. The same year, Mountain Boy drilled 2 holes targeting the lower part of Ataman zone. Hole SC16-2 returned 0.12 grams per tonne gold, 28.0 grams per tonne silver, 1.21% zinc, 0.03% lead, 0.31% copper.
In 2017, a total of 115 rock samples were collected. Of those, 24 samples were taken by a team of climbers from the top part of a prominent sericite-quartz-pyrite zone situated on the lower Ataman Zone. The remaining 91 samples were collected from other areas of the property. The 2017 drilling program consisted of two diamond drill holes totaling 345 metres. The holes were drilled from the same pad used for the 2016 drilling. Hole SC17-03 intercepted 26.05 metres averaging 22.34 grams per tonne silver, 0.36% copper, 0.03% lead, 1.03% zinc and 41.0% barite.

- Continue mapping and prospecting of the ore equivalent horizon, felsic volcanic and clastic rocks of the Mount Dilworth Formation.
- Investigation of pathfinder elements and element ratios for potential vectors towards further mineralization.
- Drill targets delineated by previous mapping and drilling, as well as any new targets identified by further exploration.
- SWIR analysis of select core and rock samples.
- Fossil collection for geochronological analysis.
