That's not how it works. The chief does not point in the direction that the collectible can be found. The collectible can be in any area of the map where collectibles normally appear. A rare collectible will always appear somewhere, but it can be hard to see if it's behind villagers (if you have a large tribe), trees or other objects. However, if you are in the habit of pausing the game to help find and gather collectibles, you may prevent one from appearing.
