Adamus Resources Ltd - Testwork Boosts Confidence in Sulphide Gold



PERTH, Western Australia, Aug. 4 /CNW/ - Single stage flotation testwork on our fresh sulphide mineral resource shows:

    -   Up to 20 times gold concentrate upgrade factor
    -   Up to 92% of the gold can be captured in only 5% of the ore mass
    -   A high grade concentrate assaying 45g/t Au from the samples tested
    -   A product suitable for treatment using bacterial oxidation
    -   Clear economic potential in addition to the company's existing Ore

Adamus Resources is pleased to announce excellent results have been obtained to date from the ongoing metallurgical testwork being conducted on the Salman Trend sulphide mineralisation. Results to date confirm and improve upon earlier testwork.

None of the Salman Trend sulphide mineral resources is contained within the current published Ore Reserve and mine plan. Accordingly, any processing of the sulphide would be additional to current reserve base.

The testwork is being undertaken by SGS Minerals Limited in Perth under the supervision of Mr Allan Brown who has over 40 years metallurgical experience, including many years operational BIOX plant experience obtained in plants in several countries.

Adamus has confirmed that a valuable concentrate from the Salman sulphide mineralisation can be made by flotation. The concentrate produced in the first rougher float stages grades at 45g/t Au and contains up to 92% of the available gold. This is an approximate mass pull of 5% producing a concentrate sulphide content of 16%, which is an excellent result. Further rougher float stages after the initial sulphide concentrate recover a further 7% of the gold, leaving a float tail of less than 2% or 0.05g/t. More optimisation of the float chemistry is expected to marginally improve this result.


The results clearly demonstrate potential to unlock further value from the Salman Trend which remains open with fresh sulphides along its entire 9km strike length. Significant quantities of material are already known to exist at one pit at Salman Central down to only 150m depth. Salman Central occupies only 15% of the 9km Salman Trend, most of which has been drilled to only 80 - 100m depth.

Similarity of the Salman Trend sulphide ore to adjacent BIOXtm operations in Ghana suggests a flotation concentrate will be suitable for bacterial oxidation processing. Tests are being conducted to prove this.

Obvious potential exists to process gold concentrate in a nearby BIOXtm processing plant. Alternative options are also being considered.

To view Figures 1, 2 and 3 - follow the link:

Adamus has developed a model based on the current testwork results. The model used Whittle Optimising software and assumed estimated mining, flotation and treatment costs for a 1mtpa ore circuit. The optimisation demonstrated that a large percentage of the current Salman Sulphide Mineral Resource could convert to a Reserve and be available for economic processing. Significantly, the economic model 'bottomed-out' and showed all material to be economic to the extent of the current drilling. This indicates that further, deeper resources may be economic once identified.

Exploration drilling to further extend the current shallow sulphide mineral resources to depth has been planned and is set to commence during August. Negotiations for processing will continue concurrently.

Strongly encouraged by the result, Adamus is continuing with flotation optimisation studies and bacterial oxidation testwork. Based on the samples tested to date the following potential process flow is being considered.
