One of the special operations in Far Cry 6 involves finding the key location & Maceo stash, which is a chest filled with Moneda. You can access these operations by talking to Lola in the Guerilla camp. In this task, you have to kill an enemy Captain and get his explosive device. Yeah, as someone else mentioned below - I found it as well. Just found the stash key and chest with my mate. The key is near the cathedral, and the chest is in the ruins (the two dots above the cathedral on the map). "Near" is a really pinpoint location thanks for clearing that up for all of us you really helped. QV6Rqr3.
