Malian prosecutors have appealed a judge’s order to release four Barrick Mining Corp.’s employees on bail, according to people familiar with the matter.

Barrick staff, including a regional manager detained last year amid rising tensions over the company’s largest gold mine in Africa, will remain in jail pending the Court of Appeal’s review of the prosecution’s case, the people said, asking not to be identified because they’re not authorized to speak publicly on the matter.
