PDF Report 12 AMERICAN BULLION MINERALS LTD. RED CHRIS PROJECT SUMMARY OF 1995 ENVIRONMENTAL PROGRAM Preparedfor: American Bullion Minerals Ltd. 1500 - 675 West Hastings Street Vancouver, B.C. V6B 1N2 Prepared by: Hallam Knight PiCsold Ltd. Suite 1450 - 750 West Pender Street Vancouver, B.C. V6C 2T8 April 1996. SUMMARY PAGE AMERICAN BULLION MINERALS LTD. RED CHRIS PROJECT Environmental studies, which have included baseline data collection programs for hydrology (5 sites, including 2 automatic water level recorders), water quality (1 1 sites), meteorology and wildlife, and preliminary vegetation and fisheries studies, have indicated that general environmental conditions at the Red Chris project site are typical for the region. Runoff from the deposit area reflects the mineralization with elevated levels of conductivity, dissolved solids, sulphates, and metals such as aluminum, cadmium, copper, iron, manganese and zinc. Mountain goat and stone sheep habitat on Todagin Mountain is of significant concern within the immediate area. Public response from the preliminary Public Consultation Program, which consisted of a series of Open House presentations in several communities near the project site, was generally supportive of the proposed Red Chris project, Preliminary waste characterization studies on the four main rock types found within the Red Chris deposit area suggested that main phase monzodiorite and late phase dyke material will likely be acid generating. Distal volcanic rocks will likely be acid consuming; however, uroximal volcanics 1oW and siltstones will require hrther test work to determine 100 their overall acid generation potential. I _I !....

  • Landforms of British Columbia 1976
    Landforms of British Columbia A Physiographic Outline bY Bulletin 48 Stuart S. Holland 1976 FOREWORD British Columbia has more variety in its climate and scenery than any other Province of Canada. The mildness and wetness of the southern coast is in sharp contrast with the extreme dryness of the desert areas in the interior and the harshness of subarctic conditions in the northernmost parts. Moreover, in every part, climate and vegetation vary with altitude and to a lesser extent with configuration of the land. Although the Province includes almost a thousand-mile length of one of the world’s greatest mountain chains, that which borders the north Pacitic Ocean, it is not all mountainous but contains a variety of lowlands and intermontane areas. Because of the abundance of mountains, and because of its short history of settlement, a good deal of British Columbia is almost uninhabited and almost unknown. However, the concept of accessibility has changed profoundly in the past 20 years, owing largely to the use of aircraft and particularly the helicopter. There is now complete coverage by air photography, and by far the largest part of the Province has been mapped topographically and geologically. In the same period of time the highways have been very greatly improved, and the secondary roads are much more numerous. The averagecitizen is much more aware of his Province, but, although knowledge has greatly improved with access,many misconceptions remain on the part of the general public as to the precise meaning even of such names as Cascade Mountains, Fraser Plateau, and many others.

  • Upper Skeena Fish Passage Culvert Inspection
    Upper Skeena Fish Passage Culvert Inspection Ken Rabnett & Tim Wilson Gitksan Watershed Authorities February 2008 Upper Skeena Fish Passage Culvert Inspections 2 Gitksan Watershed Authorities February 2008 Upper Skeena Fish Passage Culvert Inspections Summary The purpose of this report is to present background information and survey results for fish passage inspections along the B.C. Rail grade located in the upper Skeena Watershed. In 2007, Gitksan Watershed Authorities (GWA) was retained by the Pacific Salmon Commission to conduct a Fish Passage and Culvert Inspection (FPCI) on all non-bridged B.C. Rail crossings of fish bearing streams in the upper Skeena Watershed. The upper Skeena Watershed fish passage assessment is the final component of a regional effort to improve fish passage limited by highways, secondary roads, and railway grades throughout high and very high value fish habitat in the Skeena Basin. This fish passage inspection project focused on the BC Rail grade, which enters the Skeena Watershed a few kilometres south of Bear Lake, traverses Bear Lake and River, passes Sustut River on the north bank, and goes upstream on the Skeena River northbank passing into the Stikine drainage. The B.C. Rail grade is 195 km in length within the Skeena Watershed. The primary objective of this project was to focus on increasing the abundance of fish stocks by opening freshwater habitat to salmon spawning and rearing. This project utilized the fish passage culvert inspection procedure developed to evaluate one of the most easily addressed fish habitat constraints: access to existing habitat. The methodology is based on the BC Government fish passage protocol outlined in Fish Passage – Culvert Inspection Procedures.

  • Assessment of Lower Klappan River and Tributary Crossings
    Assessment of Lower Klappan River and Tributary Crossings Prepared for Klabona Keepers Society Ken Rabnett Suskwa Research September 2007 Assessment of Lower Klappan River and Tributary Crossings Cover photo shows view downstream from Klappan Bridge to Slide 1 at 24.5 km © Suskwa Research 2007 2 Suskwa Research September 2007 Assessment of Lower Klappan River and Tributary Crossings Summary The purpose of this report is to present background information and survey results for river erosion assessments conducted at selected lower Klappan stream crossings and road encroachments. In September 2007, Suskwa Research was retained by the Klabona Keepers Society to assess various sites in the lower Klappan drainage that have been impacted by either BC Rail construction or recent snowmelt flooding. This assessment is part of a larger sub-regional effort to provide baseline information to support the Klabona Land Stewardship Plan process. The primary objective of this project is to focus on Sites 1 to 5 as delineated by Shell Canada and additional sites upstream on Klappan River. Site 1 is a historic landslide located at 24.5 km just downstream of the Klappan River crossing. Site 2 is the northern approach to Klappan River Bridge crossing. Site 3 is an unnamed creek crossing the BC Rail grade at 26.5 km. Site 4 is a unnamed creek crossing the BC Rail grade at approximately 27.5 km. Site 5 is a 300 m in width section of the BC Rail grade which has been eroded by Klappan River at 29 km. In aggregate, Klabona Keepers’ view the cumulative works identified as Sites 1 to 5, as well as the other sites identified in the Shell materials such as the “Big Eddy” site, as a major project.

Ministry of Environment, Lands and Parks Abstract The purpose of the survey was to produce biophysical soil landscape unit maps to be used as a base for describing vegetation successional trends and rating land according to its capability to support wild ungulates . The report has three parts. The physiography, bedrock geology, climate, vegetation zones, and terrain are described briefly in Part 1 . The study area, which covers approximately 26 500 km2, is located within the drainages of the Stikine and Iskut Rivers in northwestern British Columbia. The area is diverse and consists of rugged, mountainous terrain influenced by a moist, marine climate in the southwest which changes to gently rolling plateaus dominated by a continental climate in the northeast.
