Administrative Order No. 2017-10 prohibiting the open-pit method of mining for copper, gold, silver and complex ores in the country remains effective at the turn of the year. This is largely due to President Duterte's decision to maintain the ban because of the perception that no corrective measures are in place to address the environmental disturbance left by an open-pit mine.

Surface mining is defined as the extraction of ore from an open pit or burrow. Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
