Erris Resources PLC (LON:ERIS) has announced positive results from preliminary metallurgical test work at the Abbeytown mine project in County Sligo, Ireland, showing straightforward standard flotation process can be utilised for the recovery of concentrates.
The AIM-listed mineral exploration company, with a portfolio of zinc and base metals projects in Ireland and gold projects in Sweden and Finland, said the metallurgical study indicated that production of a good quality, saleable concentrate can be achieved.
The company added that the results demonstrated excellent recoveries including 96.2% lead and 95.8% zinc, with high silver credits identified with 448ppm silver in the lead concentrate and 340ppm in the zinc concentrate with no significant deleterious elements.
It also said the Bond Ball Mill Work Index was 8.76kWh/t, classifying the sample as being soft with respect to grindability indicating that any potential development could enjoy favourable processing costs as it would require relatively low primary milling power requirements.
Anton du Plessis, Erris Resources’ CEO commented: "The results of the preliminary metallurgical study at Abbeytown are very positive and show that good quality lead and zinc concentrates can be produced using a standard flotation process.
“Furthermore, the recoveries are excellent, the concentrate is clean with respect to penalty elements and the grindability characteristics of the mineralised sample are positive.”
He concluded: “The results further reinforce our confidence in the economic potential of the Abbeytown project."
