The bars have passed the handheld XRF scans we are talking about.

“In the biggest news we’ve broke since the JP Morgan whistle-blower stepped forward,
Australian Bullion Dealer ABC Bullion has contacted SD to advise that one of its suppliers has provided them photographic evidence of a tungsten filled 1 kilo gold bar discovered this week.

The specific XRF device may not have been the correct one needed. The bottom line is that we know ONE TEST failed. Nothing more.
