I would think it is less than the 5% reporting threshold.
The Deutsche Bank holdings are in the hundreds of thousands range - but maybe other institutions are holding on behalf as well

Extract Resources, Kalahari Minerals, China Guangdong Nuclear Power Corp

Perth’s Extract Resources could be about to find out whether a likely downstream acquisition from China Guangdong Nuclear Power Corp is going to evaporate for the second time in seven months. Guangdong has been in renewed discussions with major Extract shareholder, the UK’s Kalahari Minerals, over a 233.55 pence per share ($1.8 billion in total) indicative proposal. But Guangdong has to announce a firm intention to bid by December 8. Otherwise talks will again be put on hiatus for six months, unless the UK Takeover Panel agrees to extend the deadline.

Kalahari owns 43 per cent of Extract – Rio Tinto owns 14 per cent, and 11.5 per cent of Kalahari – and under Australian takeover rules it would be compelled to make an offer for Extract. At the moment, Guangdong would be expected to lob a bid around $8.86 a share, valuing Extract at $2.2 billion. Extract shares surged in October when speculation of a bid was emerging but have traded at a significant discount ever since, as investors check their expectations.

Meanwhile, Cameco Corp boss Tim Gitzel, fresh from his defeat in the race for Hathor Exploration at the hands of Rio’s Tom Albanese, says he is unlikely to be tempted into pinching something from Rio’s backyard by making a play for Paladin Energy. In an interview with Bloomberg, Gitzel said the company is still on the lookout for acquisitions, but Paladin isn’t likely to be one of them.“We have the same concern about valuation,” he said. “We’ve got some other pieces and projects that we like better.”
