Maiden JORC Resource
On 01/05/2012, Rum Jungle Resources Ltd announced a maiden JORC total resource of 1.2 Mt of schoenite which is equivalent to 530,000 tonnes of potash. This resource consists of:

	Number of Lakes	Kg / m³ brine	K₂SO₄ (tonnes)
Inferred	9	3.90	52,000
Indicated	7	4.23	477,000
Total	16		530,000

It is anticipated to substantially increase this resource estimate with deeper drilling and the inclusion of other lakes.

Resource Drilling
Eight experimental vibracore holes were completed with drilling depths between 1 m and 3.5 m during September 2011. Fifty-five sonic drill holes were satisfactorily completed during October 2011. These holes averaged 3.2 m deep and penetrated through the soft lake sediment aquifer, the stiff clay aquiclude of the basal lake sediments and into the fractured Devonian siltstone aquifer beneath.

Karinga Creek Project Location Map

The Karinga Creek Potash Project is located between Erldunda and Curtin Springs along the Lasseters Highway approximately 200-300 km south west of Alice Springs. The Joint Venture is looking to produce potassium sulphate (potash - K₂SO₄) or schoenite (potassium magnesium sulphate) via solar evaporation ponds from water pumped out of the salt lake sediments and/or from the shallow underlying aquifers.

The Karinga Creek drainage system contains hundreds of salt lakes representing the eastern extension of Lake Amadeus in the Simpson Desert. These playa lakes contain brines enriched in salts such as potassium, magnesium and sulphate and were the subject of previous investigations for recovery of commercial evaporite minerals during the 1990’s.

Australia imports 100% of its potash fertiliser.
