Minemakers Limited-Wonarah Phosphate Deposit: Significant Resource Additions from 2011 Drilling Programme

TORONTO, ONTARIO--(Marketwire - Oct. 5, 2011) - Minemakers Limited (TSX:MAK)(ASX:MAK)(NSX:MMS)

HIGHLIGHTS

• An 82 hole drilling programme in 2011 has increased estimated Inferred resources for the Main Zone by approximately 60%.
  
  
• The 2011 drilling mainly tested 3-4km to the north of previously reported Main Zone resources, with approximately 90km more to be drill tested in the future.
  
  
• New Main Zone estimated resource is:

Main Zone				0% Cut-off				10% Cut-off
				Mt		% P2O5		Mt		% P2O5
		Indicated		509		12.1		252		18.2
and		Inferred		902		11		395		18

• In combination with the Arruwurra Deposit which has yet to be closed off by drilling, the total estimated Wonarah resources, effective as of October 2011 and prepared by Hellman and Schofield Pty Ltd, now stand at:

Total				0% Cut-off				10% Cut-off
				Mt		% P2O5		Mt		% P2O5
		Indicated		565		12.6		303		18.2
and		Inferred		987		11		479		18

• The additional resources resulted from a programme costing approximately AU$480,000, for a discovery cost of less than 0.3 cents per tonne.

The 2011 drilling programme aimed to test for a northerly extension of the Main Zone in the tenements north of the Barkly Highway, and to infill two un-drilled areas in the southern part of the Main Zone, as shown in red in the figure below. A further target area near the Barkly Highway, and to the west of the Main Zone, was inaccessible due to the extraordinarily severe 2010-2011 wet season.

The 2011 drilling proved general continuity of the Main Zone northwards for 3-4km from previously estimated resources. Outlying holes were drilled at insufficient density to support a resource estimate at this time, but indicate potential to outline additional resources when further drilling is undertaken in the future.

The Arruwurra deposit was not tested in the 2011 programme and it is open laterally with a reasonable expectation of a considerable increase in resources when drilled. It is regarded as a prime target by Minemakers because of its relatively thin overburden and hence likely lower potential mining cost.

The new drilling and resource estimates confirm Wonarah is by far the largest phosphate deposit known in Australia.

Mineral resource estimates were previously released in 2010 and compare with the 2011 estimates as follows:

2010 and 2011 resource estimates at 10% P2O5 cut off
					2010				2011
					Mt		% P2O5		Mt		% P2O5
Main Zone			Indicated		238		18.6		252		18.2
	and		Inferred		247		18		395		18
Arruwurra			Indicated		51		18.3		51		18.3
	and		Inferred		84		16		84		16
Total			Indicated		289		18.5		303		18.2
	and		Inferred		331		17		479		18

The 10% cut-off is used as a likely indication of feed material for a beneficiation plant on site.

2010 and 2011 resource estimates at 0% P2O5 cut off
					2010				2011
					Mt		% P2O5		Mt		% P2O5
Main Zone			Indicated		480		12.2		509		12.1
	and		Inferred		637		10		902		11
Arruwurra			Indicated		56		17.3		56		17.3
	and		Inferred		85		16		85		16
Total			Indicated		536		12.7		565		12.6
	and		Inferred		722		10.7		987		11.4

The 0% cut-off estimates represent the entire package of phosphatic units included in current estimates.

Managing Director and CEO, Andrew Drummond, stated: "The results are firmly in line with expectations as we begin to test along strike from the known deposits with the aim of optimising the first areas to be mined. This drilling programme added 163Mt to our beneficiation feed resource base at a cost of less than 0.3 cents/tonne. Total resources now stand at almost 800Mt at 18% P₂O₅ for potential early mill feed, or more than 1.5Bt at zero cut-off in the overall phosphatic horizons. It highlights the potential for Wonarah to become one of the world's premier phosphate mining centres in due course, and that additional mineralisation can be found quickly and cheaply when required in the future."

In accordance with JORC Code Clause 18, with respect to future exploration of the phosphatic target zone, the potential quantity and grade of any discovery conceptual in nature, there is insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in determination of a Mineral Resource.

Notes:

Resources have been estimated by Hellman & Schofield, Minemakers' independent resource consultants. Ordinary Kriging was used in a manner consistent with that previously reported and lodged on www.sedar.com.

There are no known legal, political, environmental or other risks that could affect the potential development of Wonarah other than those previously disclosed.
