Today, the Court of Appeal reversed that. The decision isn't very long, but the short version is "if Parliament had meant for that to happen, they would have explicitly said so". The slightly longer version is that the Crown Minerals Act regime is so different from the long-repealed legislation that the usual interpretive presumption of reading references to repealed acts as references to their corresponding replacements simply does not apply:
There is nothing that “corresponds” to the old regime in relation to minerals or coal. Those repealed provisions and the concepts behind them are gone. An entirely new regime has been put in place.Instead, the Court of Appeal relies squarely on the Crown Minerals Act provision that mining is subject to all other applicable legal obligations, and ruled that access to dig the mine is subject to the Reserves Act. Which you would hope would kill it. Of course, it will probably go to the Supreme Court, because the mining industry will not accept such a limitation on its "right" to destroy our environment. But you'd hope that they'd uphold the obvious: that reserves are for protecting, not mining.
