A placer claim is a parcel of land located or granted for placer mining. A claim also includes any ditches or water rights used for mining the claim, and all other things belonging to or used in the working of the claim for mining purposes. A placer claim is a rectangular plot of ground. All angles of a claim must be right angles, except in the cases where a boundary line of a previously located claim is adopted as common to both locations. The length of a regular placer claim from post one to post two is 500 feet along a baseline. Co-discovery claims must not exceed 1250 feet each, and single discovery claims must not exceed 1500 feet. The Placer Mining Act is available at http://www.gov.yk.ca/legislation/acts/plmi.pdf Visit http://www.emr.gov.yk.ca/mining/placermining.html for detail on how to staked, record and maintain a Placer Claim.

Yukon parks and protected areas captured from DCW 1:1,000,000 scale dataset. Boundaries were generalized from survey information captured by Legal Survey Division of Natural Resources Canada (NRCan).

Land administered by Government of Yukon, Department of Energy, Mines and Resources (EMR), for which Status = Closed. Includes any land parcels closed for any reason.

A claim is a parcel of land located or granted for hard rock mining. A claim also includes any ditches or water rights used for mining the claim and all other things belonging to or used in the working of the claim for mining purposes. A claim is a rectangular plot of ground that does not exceed 1,500' X 1,500'. All angles of a claim must be right angles, except in the cases where a boundary line of a previously located claim is adopted as common to both locations.

The Adaptive Management Framework for Yukon placer mining is complemented by traditional knowledge and monitoring of water quality objectives, aquatic health, and economic health.The aquatic Health monitoring program is governed by the Aquatic Health Monitoring Protocol.The Protocol describes the locations, timing, frequency and methods employed duringsampling, as well as the methods used to analyze sampling data. The Reference ConditionApproach (RCA) is the method chosen for assessing the health of freshwater ecosystems inthe Yukon. One RCA model was developed for bioassessment based upon benthicmacroinvertebrates, and a second model was developed to assess the diversity of fishspecies.The RCA model for invertebrates relies upon 224 reference sites collected over the period 2004 to 2010 by the University of Western Ontario, Fisheries and Oceans Canada, and theYukon government, using the same standard protocol. The invertebrate data set was analyzedat the family level.There are two fundamental steps in the process of developing the predictive model. The first isto classify the reference sites based on their biological characteristics. This requires defining anumber of community types based on the taxonomic composition. The second step is todetermine a subset of habitat attributes that are associated with those community types.Following this step the number and type of organisms expected to occur at any given site canbe determined from habitat attributes.For more information, contact the Yukon Placer Secretariat
