Instead, it would make sense to allow the income gain to flow into a higher stock of saving, which would then be available to fund future consumption (including through periods of temporarily weak terms of trade, which undoubtedly will occur in the future).
Moreover, it would probably not make sense for there to be a big increase in investment in resource extraction if that investment could be profitable only at temporarily very high prices (and which could come at the cost of reduced investment in other areas). If the change is likely to be persistent, then income is likely to be seen as permanently higher.
