American Creek

Overview

Project Summary

Size 2,602 hectares
Location The American Creek 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.
Infrastructure The east end of the American Creek Project is accessible by road; the paved Stewart Highway and electrical transmission line is just 5 kilometres south of the property; the deep water sea port of Stewart, BC is 20 kilometres away; the southwest end of the property is 6 kilometres from the Premier mill.

Highlights:

  • Centered on a past-producing high-grade silver mine.
  • Adjacent and on-trend with a past producing gold and copper mine.
  • Exceptionally high-grade silver values from earlier work.
  • Multiple mineralized horizons extending over several kilometers.
  • Favourable host stratigraphy, including rocks from the Lower and Upper Hazelton Group.
  • Uranium-Lead zircon geochronology confirming the presence of Early Jurassic intrusions on the property.
  • Abundant evidence of large, continuous regional and property scale faults, folds 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 epithermal and structurally controlled precious and base metal deposits.

Mountain Boy has consolidated a significant land package in the American Creek corridor. The property is host to a variety of targets with several known mineral occurrences, all of which are under explored.

Mountain Boy Minerals considers the area to have real potential to host one or more deposits. The presence of numerous nearby past producers, an evolving understanding of the geology and encouraging results, as well as discoveries in the region all support the highly prospective nature of the MTB property.

Mapping and prospecting on the project has lead to the discovery a new area of gold-silver-base metal mineralization on Bear River Ridge, confirmed the presence of a silver and base metal intermediate epithermal system along a ~ 2 km trend and discovered an Early Jurassic latite porphyry intrusion below the epithermal system. This previously unrecognized intrusion is similar in age to the many Jurassic Intrusions that are related to several of the deposits in the area including the Premier Porphyry, which is directly related to the historic Premier Mine, 11 kilometres to the southwest.

The Stewart Mining camp is part of the larger Golden Triangle and contains well over 200 mineral occurrences. Lead isotope studies in the area have identified two distinct mineralizing events characterized by different base and precious metal suites. One ore forming episode occurred in the Early Jurassic; the other episode occurred in the Paleogene. Both episodes were relatively brief geologically, but regional in scale. The current working deposit model for American Creek includes two styles and both ages of mineralization.

The older style consists of multi-pulsed epithermal mineralization, with the Early Jurassic intrusion identified on the property providing a possible magmatic heat source for circulating metal bearing fluids.

The second style consists of structurally controlled mineralization associated with the emplacement of Middle Eocene dyke swarms and stocks of the Coast Plutonic Complex.

The American Creek Project has district scale potential for both ages of mineralization. It is strategically located amongst many world class deposits including the historic Premier mine 11 kilometres to the southwest and the Big Missouri 3 kilometres to the west. The latest mine in the area is Pretium’s Brucejack deposit located 30 kilometres to the north. Other past producers in the immediate area include the Silver Coin, Red Cliff, Scottie Gold, Dunwell and Mountain Boy mines. Ascot Resources has just released robust results on an independent feasibility study that would involve developing four underground mining operations at the past producing Silver Coin, Big Missouri and Premier and the new Red Mountain deposit. The four mines would feed a refurbished 2,500 tpd mill at Premier. All these deposits are part of the Early Jurassic mineralizing event.

The historic Porter Idaho, Silverado and Riverside mines are examples of Paleocene high-grade silver-lead-zinc vein deposits within the Stewart camp.
