The Government of Yukon, Government of Canada, the Kwanlin Dun First Nation and the CarcrossTTagish First Nation agreed to create a 20.02 square kilometres Special Management Area designated as a Habitat Protection Area surrounding the Lewes River Marsh wetland below and including the lower end of Marsh Lake. The Government of Yukon, Government of Canada and the Carcross/Tagish First Nation agreed to create a 4.62 square kilometer Special Management Area designated as a Habitat Protection area along the Tagish River including the delta deposits in upper Marsh Lake.
The northern portion of the proposed Lewes Marsh/McClintock Bay Wetland Special Management Area is within the Traditional Territory of the Ta'an Kwach'an Council. The purpose of this report is to present the results of the detailed mineral assessment of an area of 310 square kilometers that encompassed the two proposed Special Management Areas.
The proposed area has no advanced mineral deposits. The assessment is based on the mineral potential of the geology as identified by a panel of industry experts. Results shown on the detailed mineral potential map indicate that the highest relative mineral potential lies in the tracts east of the Alaska Highway beside the proposed Lewes Marsh/McClintock Bay Wetland Special Management Area. The western tract boundary of the highest ranking coincides with the trace of the Marsh Lake Fault Zone. The Marsh Lake Fault Zone has been identified as gold bearing over a 500-metre strike length at the Rossbank property Creek Zone (Minfile 105D 102). Mid Cretaceous aged mafic to intermediate volcanic rocks, limestone and chert that have the potential for hosting significant economic metal deposits underlie the tracts of relative highest mineral potential.
