Ann: Outstanding 813m Cu-Au Intercept at Cortadera, page-33

the mineralisation started at 54m below the surface and continued for 813m until the hole was abandoned. "To end of hole" means the mineralisation continued to the location at which the hole was abandoned, and no further drilling occurred because of equipment failure.

There is a chance they could track down that hole in the future and continue drilling, however this would depend on a number of factors, such as whether they lost the drilling rods down the hole. I suspect they might utilize the information gathered from this hole and plan another drill hole nearby to test the mineralisation at depth, but who knows!
