Gold Canyon Resources Inc. Springpole Gold Access Corridor Project Final Environmental Study Report lower potential for negative effects compared with the western corridor. This is primarily due to synergies of the eastern corridor with the future planned FMP Approved Road. 7.0 SIGNIFICANCE OF RESIDUAL NEGATIVE EFFECTS Significance of residual negative effects, after mitigation measures are applied, is commonly considered in the context of its magnitude, geographic extent, duration, frequency, degree of reversibility, possibility of occurrence or any combination of these factors. Conventional considerations for significance criteria for environmental assessments are defined in Table 7-1, as well as a description of the significance level (low, medium and high) for each criterion. As presented in Table 7-1, significance in this EA analysis is a gradient of low to high, in general accordance with guidance in MNR (2003), section 3.3, page 20. The relevant excerpt from MNR (2003) is provided in the bullets below for convenience. A “low” net effect would be assigned where there is a high degree of certainty as to the effect, and where the effect has minimal significance. A “medium” net effect may be based on reasonable certainty, and may be significant in combination with other medium and high net effects. A “high” net effect may reflect high level of certainty that a significant effect will occur, or a low level of certainty about one or more effects and a need for further evaluation and exploration of mitigation options. Potentially significant negative effects associated with the Project are listed in Table 6-1 along with mitigation measures. The significance of these residual effects after mitigation measures are applied has been assessed in accordance with Table 7-1 and is described in Table 7-2. Please note, a full discussion of potential overall benefit measures related to caribou are presented in Appendices 4 and 10. The overall benefit measures that are discussed herein would be formalized in an Overall Benefit permit that is issued for the Project following the conclusion of the EA (refer to Section 3.4).
