Be very careful - out of the JORC Metallurgical Factors & assumptions used - the answer is not 99%.

Same results back in 1985 - to be safe do your economics between 62.5% - 75%

Metallurgical studies undertaken on recent drilling data (143 samples) indicated a gold recovery in fresh ore material ranging from 57.7% to 99.7% from leachwell analysis. The average gold recovery for fresh material beneath the current pit design is 85%. Higher grade material returned better gold recoveries than lower grade. • It should be noted that Entech has relied on metallurgical studies undertaken by MOY and understands that the Bartons ‘fresh’ material from underground is able to be treated within the existing Criteria JORC Code explanation Commentary plant infrastructure with expected recoveries averaging 85%.

Entech understands recent test work has indicated recoveries may be affected by a combination of graphitic shales and gold bound within arsenopyrite. Test work is ongoing and optimisation studies are underway at the time of the Mineral Resource Estimate.

Future MRE updates should include estimation of Arsenic variable and geological interpretation of graphitic shale location, volumes to assist in metallurgical management at Bartons. • No metallurgical recovery factors have been applied to the Mineral Resources or Resource Tabulations.

Hi RT what happened in 1985?

PS I’m glad 2017 is over Moy managed to miss nearly every production target they set. Pretty disappointing result in 4th quarter 2017.

Now we know why the price has remained subdued while the gold price has improved.

On a positive at least the company has provided a bit more information on drilling program ahead in this announcement.
MOY Price at posting: 18.5¢ Sentiment: Hold Disclosure: Held
