Black foliated masses of hulsite throughout this matrix with biotite and greenish epidote. Good rich example for this rare mineral. The specimen comes with a previous label from the collection of Eric Laskowski.Brooks Mountain, located in the York Mountains of the western Seward Peninsula within Nome Borough, Alaska, features a rugged landscape formed by sedimentary and limestone rocks intruded by granitic plutons, resulting in significant contact-metasomatic tin deposits. Discovered and explored during early twentieth-century tin prospecting surges in the region, the area is notably recognized as a type locality for the rare tin-bearing iron magnesium borate mineral hulsite, which occurs within these unique skarn environments and attracts mineral collectors worldwide.
