Funny you should mention Lilydale, I was browsing the AFR last week and noted this in one of the articles:

"As it matured, the Japanese steel industry became legendarily fussy about a whole lot more than just the iron content of the ores it acquired. In the name of generating maximum productivity and return from its mill infrastructure, the Japanese producers became increasing obsessive after the 1980s about ore impurities that constrained mill efficiency. So above spec ranges of demons like alumina, silica and phosphorous were punished by price penalties.

That very Japanese habit has now crossed the East China Sea.

"It is absolutely clear that all customers in China are becoming closer to the customers we have in Japan," JS said."

I found that interesting so went off to find how HAV's ore might compare in terms of impurities and found this:

"The levels of impurity elements such as silica, alumina, phosporous and titanium are low, indicating that a high purity, high value magnetite concentrate can be produced."

Curiously, though, the references to Lilydale seem to have all but disappeared from the project overview section of the HAV webpage so I'm not sure what's going on there.

But, as you say, those low impurities seem to be a feature of HAV's ore and could well be a selling point as highlighted in the AFR article.
