AHN has Direct Shipping Ore haematite to go
AHN has significant outcropping haematite mineralisation in the north of its tenements.
Sampling suggests an in‐situ grade of about 56 per cent iron.
The deposits are near the Mullewa‐Carnarvon Road and up to 2.5 million tonne per year can be trucked for export through Geraldton, where there is spare capacity.
Beer & Co expect that an in‐pit crush can upgrade the ore to about 59 per cent iron.
Beer & Co estimates Life of Mine costs will be US$73 per tonne, adjusted for grade.
Our estimated NPV for this project is $44 million.
AHN has an exciting nickel-copper‐PGE prospect
Milly Milly is a six kilometre long intrusion on the northern crustal margin of the Yilgarn Craton.
Soil and rock chip sampling has yielded up to 2.5 per cent nickel from rock/laterite and up to 9 per cent copper from gossans.
Shallow drilling has yielded best results of 13.7 metres at 1.2 per cent nickel and 67m at 0.7 per cent copper, including 18.3m at 1.14 per cent copper.
AHN has drilled one deep hole which provided encouraging results.
AHN will undertake further geo‐physical surveys to design the next deep hole.
AHN has an Exploration Target of over 400 million tonnes of coarse magnetite.
AHN reported, in October 2011, that a plant to produce 2.5 million tonnes per year of 68 per cent iron concentrate had a capital cost of $136 million and operating costs of $42.3 million per annum.
Beer & Co estimate an NPV of $170 million for this project, with AISC costs, adjusted for grade, of US$63 per tonne.
There is significant upside to our valuation from a more effective transport solution, such as rail, as AHN appears to have sufficient mineralisation to make this feasible.

Unlocking a new Intrusion Related Gold Province
Renaissance Minerals Limited is a quality gold explorer looking to transition to producer through the development of the company’s 100 per cent-owned Okvau gold (+1.2 million ounces) deposit in Cambodia.
Okvau is hosted in an intrusion related gold system (IRGS), which is largely unexplored and has the potential to be a significant new gold province.
IRGS have wide-ranging characteristics, but on a basic level are gold deposits produced by local-scale fluids derived from a cooling pluton in regions lacking copper.
These mineralised systems rarely form in isolation and can host a significant volume of gold, which bodes well for more discoveries to come.
Okvau – A quality resource which is expected to grow
The 1.2 million ounce Okvau deposit is a high-quality gold resource; it is shallow (low strip ratio expected), good-grade (2.4 grams per tonne gold at a 0.65g/t gold lower cut) and robust (90 per cent Indicated resource).
Mineralisation also remains open to the north-east, south-east and at depth, as such further resource growth is anticipated.
The gold mineralisation does however have a strong association with sulphides (pyrrhotite and arsenopyrite veining), which is common among IRGS deposits (ie they are often “refractory”), and recently completed metallurgical testwork indicates that sulphide flotation followed by fine grinding of the concentrate prior to cyanide leaching will be required to achieve ideal gold recoveries.
The current conceptual flow sheet for processing is a coarse primary grind and sulphide flotation to generate a high-grade concentrate which is then reground prior to cyanide leaching.
Gold recoveries nearing 90 per cent have been achieved, and importantly no oxidation is required.
With available cheap grid power nearby, processing costs are not expected to be onerous, and should be similar to conventional processing.
The met-testwork to refine recoveries is ongoing and work has already commenced on a scoping level study into the potential development of Okvau.
On current timing the scoping study should be released in Sep 2014.
Highly prospective mineralised trend north of Okvau
Surrounding Okvau the company has plus-400 square kilometres to explore with highly prospective geology and multiple drill ready targets remain to be tested.
An initial area of focus is within a 5sqkm radius of Okvau, where gold-in-soil anomalies with coincident IRG pathfinders (bismuth, arsenic and tellurium) have been defined over large plus-800m zones.
A recent trench sample at the Area 1 prospect (located approx. 3km north of Okvau) returned 17m at 2.9g/t gold, including 9m at 4.8g/t gold over a soil anomaly more than double the size of Okvau deposit.
Follow-up drilling is planned to test this and other nearby targets.
