American Creek West

TARGET: District scale potential for gold/silver and base metal deposits similar in style and scale to: Big Missouri (less than 3.5 km to the west), Premier Mine (less than 10 km west), Red Cliff (immediately adjacent to the south), Red Mountain (20 km southeast) and, Brucejack (30 km north). Several individual targets are discussed separately below.

INFRASTRUCTURE:  Paved Stewart Highway (37A) and electrical transmission line close to the property; town and deep-water port within 25 km.

SIZE:   2646 hectares


  • Favourable host stratigraphy, including rocks from the Lower to Middle Jurassic Mount Dilworth formation and Lower Jurassic Hazelton Group.
  • Presence of potential heat sources in the area: the metalliferous Early Jurassic Texas Creek intrusions have been mapped 5.5 km south of the property, 8 km to the west,10 km to the east in the Bear Pass area and are believed to occur within the project area.
  • Abundant evidence of large, continuous regional and property scale faults and shear zones, which are often related to mineralization in the region.
  • Significant alteration and mineralization observed along the American Creek corridor.
  • Consolidation of a large land package prospective for volcanogenic hosted massive sulphide deposits and intrusion related gold-silver deposits.
  • Co-operation of Mountain Boy Minerals and Auramex in exploration of their adjacent properties representing a large, prospective area of the Golden Triangle.

Mountain Boy Minerals is well situated in the American Creek corridor. The company holds a significant land package that is host to a variety of targets with several known mineral occurrences, all of which are under explored.

Within 6.5 km, there are 17 recorded past producers;15 of the 17 past producers are hosted within the same lithology that encompasses much of the American Creek West project area. The company has a working hypothesis that much of the mineralization is related to the same metallogenic event and part of a large-scale metalliferous hydrothermal system.

Mountain Boy Minerals considers this area to have real potential to host one or more deposits. The presence of numerous nearby past producers, new geological interpretation of the area, and encouraging results in the region all support the idea that this area is highly prospective. For example, drilling by Pretium Resources Inc. on their American Creek Zone included holes within 5 km of the project area and produced significant values of gold and silver within that zone (

Mountain Boy Minerals and Auramex, with contiguous projects along American Creek, are conducting a cooperative exploration program. The multiple mineral occurrences on both sides of American Creek are now seen as related to an extensive and robust mineralizing system extending along American Creek.

The American Creek corridor is now being targeted with modern exploration across geological units without the constraints of property boundaries over a 10 km strike length. Compilation and interpretation of historic data combined with recent field work has revealed and continues to produce exceptional geological insights for the American Creek West project.



TARGET:  Replacement style mineralization on the property consists of at least seven main and four minor replacement zones tested with trenches, previous open cuts, limited diamond drilling and adits. The mineralization occurs along alteration zones that are up to 15 metres thick consisting of mainly barite, quartz, jasper, carbonates and sulphides with local native silver. Acanthite (silver sulphide) and stromeyerite (silver-copper sulphide) occur as veinlets, stringers and lenses in the high-grade and No. 3 vein, giving rise to bonanza-style grades.

LOCATION:  The MB Silver project is located in the “Golden Triangle” area of the Skeena Mining Division of British Golden; 22 kilometres north of Stewart and 7 kilometres from Highway 37A.

STAGE:  Early stage exploration, building on historic exploration including limited production in the early 1900s. Multiple gold-silver and base metal showings were each examined in isolation.

PREMISE: Several historic mines all within a 10 sq km area produced exceptionally high silver values; high silver grades were supported by limited modern drilling at one of the mines. The exploration concept is the presence of an extensive hydrothermal mineralizing system underlying the historic mines. In line with other geological systems of this type, mineralization would zone from high grade silver-base metal mineralization high in the system down through a gold-copper rich zone, which will be targeted from the valley.

PRIOR WORK: The Mountain Boy area was explored from 1902 by way of tunnels developed along the high-grade silver veins. Several tonnes of material were transported by pack horses from the mine at plus 900 metres elevation to the valley and then 25 kilometres to Stewart, for shipment to a smelter. Mountain Boy acquired the property in 2005 and conducted drilling in 2006 and 2007. Results of the drilling included DDH-MB-2006-10 which yielded 5.18 metres of 5258 g/t silver and DDH-MB-2006-19 which yielded 6.10 metres of 2260 g/t silver along with credits of lead, zinc and copper.

OWNERSHIP:  100% owned

SIZE:  650 ha

INFRASTRUCTURE:  Mountain Boy mine access road to the property; electrical transmission line and paved Stewart Highway 5 km southeast of the property.



TARGET: Shear hosted epigenetic polymetallic veins and breccias Ag-Au-Pb-Zn, Epithermal minerlization, Volcanic hosted massive sulphide (VHMS) mineralization.

LOCATION:  22 km north of Stewart, west of American Creek, 1 km west of Red Cliff mine (Decade/Mountain Boy), 3.5 km east of Big Missouri Mine, and 6.4 km northeast from past producer Premier mine.

STAGE:  Early stage exploration with limited sampling to date. Helicopter-Borne AerotTEM II Electromagentic and Magnetic Survey geophysics have been conducted and reconnaissance style mapping and sampling.

PREMISE: Several historic mines in very close proximity, for examples, less than 400 m to the west is the Spider past producer, from which a sample collected from one of the open-cuts assayed 4.8 g/t gold, 2,290.3 g/t silver, and 3.0% zinc (Ministry of Mines Annual Report, 1936, p. B29). The project is within 3.5 km of the historic Big Missouri Mine, which in 1904 and from 1927 to 1942 produced 847,612 tons of ore using underground mining methods, and 6.4 km from the famous historic Premier mine, where from 1989 to 1996 Premier Gold produced 3,039,680 tons grading 0.085 oz./t gold and 1.67 oz/t silver. At the time of the mill closure in 1996, the property contained 350,140 tonnes of ore grading 7.19 g/t gold, 37.7 g/t silver and 1.6% zinc. See Minfile 104B 054 for a detailed production report for the Silbak-Premier Mine. The current exploration model is that these historic past producers and other mineral occurrences in close proximity are part of an extensive mineralizing system that generated the historic mines. The Silver Crown property is underexplored with good potential for hosting significant mineralization.

PRIOR WORK: After the 1919 discovery and subsequent exploration of the famous Premier mine, located 8km southwest of the Silver Crown property, the surrounding region was intensively prospected. In 1965, D. Collison discovered polymetallic vein mineralization in the same area over a strike length of 450m. This showing eventually became known as the Silver Crown. E.W. Grove describes the Silver Crown showing in detail in Bulletin No. 58 (1971). He was of the opinion (private communication with D. Cremonese, Assessment Report 28,408) that the area deserved detailed examination due to potential affinities with the Premier mine showings. Teuton Resources staked the property and did minor prospecting on it in the early 1980’s and carried out an airborne survey over it in 1987. In 1989, after Teuton allowed the property to lapse, White Channel Resources and thereafter Navarre Resources followed up with work on the claims including sampling, geophysical surveying, geological mapping and diamond drilling. Although several narrow high-grade silver-lead-zinc veins were encountered in this work, delineation of larger precious metal bearing structures proved elusive. The claims were eventually dropped and remained open until Teuton Resources picked up the property again in 2003 (Assessment report 28,408).

INFRASTRUCTURE:  Electrical transmission line and paved Stewart Highway 2 ½ km south of the property; Mountain Boy mine access road crosses the property.



TARGET:  Gold-silver carbonate replacement deposits; shear-hosted gold-silver deposits. Previous exploration has discovered up to 15 quartz-barite carbonate replacement occurrences within the claim group. The target is large and high grade.

LOCATION:  22 km north of Stewart, along the American Creek valley, 2 km northeast of Red Cliff mine (Decade/Mountain Boy).

STAGE:  Early stage exploration, building on historic exploration including limited production in the early 1900s. Multiple gold-silver and base metal showings were each examined in isolation.

PREMISE: Historically, the property was subdivided into three main zones of interest: the Maybee Zone, Lucky Jim Zone and the Ruby Zone. The Maybee Zone is host to the Maybee Vein and to the north the proposed vein extension has been reported. The Lucky Jim Zone contains the Joven vein, Maurice zone, Argen zone and the Akash vein including the newly discovered Gurjaan and Jesse showings. This zone covers a large area with historic showings and workings that still need to be explored. The Ruby zone covers the lower slopes in the south end of the property group. The zone contains the Damon vein and the historic Jewelry Box vein including the elusive Peacock Vein.

PRIOR WORK: Prospecting began in the Portland Canal area about 1898 and moved northward into the American Creek area. The first claims that were staked in the area were the American Girl and Mountain Boy claims in 1902 which adjoin the Dorothy claims to the south. The area encompassed by the Dorothy claims have been explored sporadically since 1904 when some stripping and open cutting was recorded on the Ruby claim. In 1905 four open trenches were dug on the Maybee and Louise claims for a total of 80ft. Reports state that high grade silver and copper mineralization is similar on both claims. During the same period work performed on the Ruby and Mourning Star claims included one 15ft exploration adit and 63ft of trenching.

In 1990, Teuton Resources purchase the Lucky Jim claims and conducted a limited geochemical survey (Assessment Report 21,405). 16 rock samples were collected from the property and returned values of 0.244 oz/ton gold, 8.14% lead and 5.24% zinc from old trenches (sample JM-R-4).

In 2000, D.K. Bragg conducted a prospecting and topographic mapping program on the Golden Genesis Property, which covers the current claims. The subsequent report mentions silver assays to 771.26 oz/ton, combined lead/zinc up to 65% and gold values as high as 1.893 oz/ton from grab samples. Unfortunately, the locations of the grab samples remain unknown.

Underground workings and drilling on properties to the south (Mann and High Grade Veins) indicate mineralization zones in the area have some depth potential and the mineralized trend is projected toward the Lucky Jim Zone on the Dorothy 1 claim (Assessment Report 36,149).
