Thank you, Mr. Chair. This section, clause 53 deals with a change in material, a material change to an undertaking authorized under the mineral release. Can the Minister just explain clearly what this section contemplates because I think there's a concern? What does a material change look like, and does that mean an entire benefit agreement needs to be shifted to reflect that change? Can the Minister just explain how this would play out? How the department envisions this to play out in reality? Thank you, Mr. Chair.
