Oceania (OGC, 2.3 billion AUD MC) runs the Martha Mine in Waihi township. They're not a small company, and may be interested.
But lets not forget that NTL bought Rahu back off of Newcrest Mining Limited (NCM, 27.7 billion AUD MC).
There's more than one player around in that area.
NCM is over 10 times the market cap of OGC, and already has cash trading relationships with NTL.
