Orebody formPINCH AND SWELL
Ore control"NW to WNW trending, steeply north-dipping sphalerite-rich veins along the Star-Morning Fault contain the largest orebodies.", "EW to ENE trending, steeply N-dipping, galena-rich veins along the Star Morning Fault.", "Intersection of two vein systems plunges steeply east, giving orebodies a very steep east rake.", "Bedding strikes N-S and dips steeply east or, locally, steeply overturned to the west. Veins are subparallel to an intense cleaveage in the quartzite. The intersection of veins and bedding plunges east.", "The Morning-Star vein is zone laterally, with eastern (Morning) portion being galena-rich, and the western (Star) portion being sphalerite rich. Iron content of sphalerite increases toward the top of the vein."

Geology
Host rockQuartzite · "Burke Formation", "St. Regis Formation", "Revett Formation"
Structure"Anticline (WNW) - veins in south upright limb.", "Star-Morning Fault, a feather joint off a shear plane complementary to the Osburn Fault.", "Osburn Fault (WNW) to south."
Tectonic setting"Belt Basin"
Alteration"Sericitization; Chlorite; Biotite; Siderite", "Zone of disseminated siderite extends 10s to 100s of meters out from the veins, passing into a siderite-ankerite zone up to 10s of meters wide, and then into a zone of ankerite-calcite 100s of meters wide."
