Staking a mining claim is one of the first steps of the mine exploration process. This booklet is intended to provide guidance on that process in Ontario, from the preparation stage to completing & submitting an application to record a mining claim. It includes information on such matters as claim boundaries, claim tags & posts, tools used, staking in designated areas, staking single- and multiple-unit claims, use of line posts, witnessing claim corners, irregularly shaped claims, and staking in subdivided townships. Includes examples of mining claim registration forms.
