Silver Bluff (Pathfinder)

From publisher blurb:

Silver Bluff provides respite from the nearby harsh mountains. Chief among these is Mount Argent, which the villagers mine for its namesake silver on behalf of the Hargrave’s Resources mining company. However, the respite is anything but welcome, as the miners distrust each other as much as they do strangers. The rich silver seams the miners have worked for over fifty years have dried up. While the recent discovery of powdered adamantine temporarily buoyed hopes among the villagers, a grisly murder has put everyone on edge.
