cross-course
A vein or lode that crosses the main lode, sometimes accompanied by a change of course in the main lode.
Why this one
A vein that crosses the main lode. Miners were mapping structural geology in working vocabulary long before the science existed.
In use
We lost the good ground where that cross-course came through, and the lode kicked west of it by a good few feet.
