Meanings

1. A vein or lode that crosses the main lode, sometimes accompanied by a change of course in the main lode.
   • Williams's lode heaves the cross-course 4 feet towards the left-hand; the cross-course then intersects Trathan's lode, and at some levels heaves it towards the right-hand; and lastly, it heaves the Black lode 11 feet towards the left-hand. 1843, The Philosophical Magazine:
   • The north section of the mine has also a crossback or cross-course, but the result at the crossing is so completely reversed that one is struck with astonishment to see the opposites in the same formation. 1894, North of England Institute of Mining and Mechanical Engineers, Transactions - Volume 43, page 440:
   • In this end the main part of the lode is probably missed, but the branch on which it is driving has a rather silver character; and as the cross-course is approached, it is not improbably that the silver may be met with here. 1862, The Mining and Smelting Magazine - Volume 2, page 80:
