Ann: Resources Rising Stars Investor Presentation, page-3

Some see problems while others opportunities...
In my opinion it is an Excellent plan and the challenge is manageable by future "Horizon" joint and v. experienced as well as a clever management... 
It reminds me of NST story (which I was holding) ... and that's the way to go about growing... you need guts and experience and Horizon will have it all...
Just read the Paulsen gold mine of which NST grew ...as they purchased a "depleted mine" and grew to today's arguably the best gold mining business in OZ:

"The mine was expected to cease production in early 2010, when its currently known resources were depleted. Intrepid was aiming to extend the mine life by further exploration drilling. In the first half of 2009, the mine has produced 44,656 ounces of gold. The plant was placed in care and maintenance in February 2010, but recommenced production in June.^[10]

Intrepid sold the mine to Northern Star Resources in July 2010 for A$40 million.<sup>[2]"
