A dark gray nodule of chalcocite with a small bleb of covellite near the top. I collected a hand full of these using a metal detector. A very copper rich specimen.

Brown mammillary cluster of goethite on quartz crystals.
Apple green fibrous crystals of creaseyite on cerussite encrusted by a undetermined gray mineral that I suspect is chrysocolla.
A dark blue nodule of covellite with lighter blue chrysocolla. I originally thought this to be chalcocite until I cleaned it. The covellite is throughout the whole rock.
Window pane wulfenite with blue chrysocolla on a gossan host rock.
Green malachite crystals in a quartz vug with an attached small crystal of azurite!
Colorless crystals of cerussite with blue chrysocolla and brown limonite.
A patch of cerussite mostly encrusted over by an undetermined blueish gray mineral along with some bonus patches of apple green creaseyite. See child photo for a close up of the creaseyite.
A lemon yellow cluster of mimetite crystals on a gossan matrix.
A group of cream colored hexagonal mimetite crystals on hematite.
Greenish botryoidal smithsonite, colorless spheres of fluorite and blue chrysocolla. The fluorite only was made evident to me by checking with a uv light.
Almost colorless wulfenite crystals partially embedded in blue chrysocolla.
Brownish wulfenite crystals with blue chrysocolla on a gossan matrix.
A patch of cerussite mostly coated by an undetermined blueish gray mineral along with some bonus patches of apple green creasetite. see child photo for a close up of the creasetite.
A short adit (Bob's adit) with a carbide lamp written entrance tag. Some decent copper and lead minerals were collected here. March 7, 2026 photo.
