My observation is that the "lode" ended abruptly, that is , it didn't tail out slowly. This to me signifies a fault or slip of possibly some significant distance, perhaps even a few thousand metres. IMO the continuation is definitely there---it just needs to be located and with modern tech. that shouldn't be too difficult.
Broken Hill Type Silver–Lead–Zinc Broken Hill type silver–lead–zinc deposits occur within high-grade metamorphic rocks in the Eastern Fold Belt Province. Cannington is the only major example. Gold has been produced mainly as a by-product of copper from the iron oxide–copper–gold deposits of the Eastern Fold Belt Province. However, a significant exception occurs at the now mined-out Tick Hill deposit where high-grade gold mineralisation occurred within quartz-feldspar 'laminite' bands within a broader strongly strained ?high strain zone in the Corella Formation of the Eastern Fold Belt Province (Forrestal & others, 1998). This deposit forms a remarkable and important exception in that it produced 15 900kg of gold at an extraordinary average grade of 22.5g/t and is a unique but poorly understood deposit style. Culpeper & others (2000) and Denaro & others (1999a, 1999b, 2001b, 2003a, 2003b, 2004a) provide overviews of the outcropping mineralisation of this orogen by 1:250 000 map sheet.
