Herencia Resources To Commence DMS Process On Paguanta Ore

18th Jun 2010 10:54

LONDON (Dow Jones)--Herencia Resources Plc (HER.LN), an exploration company, announced Friday that independent laboratory Mintek, of South Africa, have been engaged to conduct Heavy Liquid Separation or HLS test work to determine if the Paguanta ore types are amenable to a Dense Media Separation or DMS process. MAIN FACTS: -HLS is used to simulate the process of DMS which could be undertaken on a commercial scale if and when Paguanta entered production. -The HLS technique separates ore particles using variances in specific gravity or SG, where particles either sink or float through a fluid of intermediate density. -A large proportion of low density waste may be 'floated" and discarded during the DMS process, hence increasing the metal content per ton of ore presented to the grinding and flotation plant. -Test work will be conducted on drill core obtained from the current 2010 diamond drill program and it is anticipated that the test work will commence in July 2010 with results expected to be available by September 2010 -The DMS process route will be evaluated prior to commencement a Feasibility Study possibly set to commence in the last quarter of 2010. -Subject to the results, a DMS circuit may be included within the final processing flow-sheet. -The potential benefits of DMS for the Paguanta Project include: -A significantly smaller grinding and flotation circuit as a higher proportion of waste would be rejected prior to grinding and flotation. -Cost effective beneficiation of lower grade sections of the mineral resource are possible to the point where lower grade mineralization could become economic to mine and process. -A more consistent floatation feed grade resulting in improved metallurgical efficiencies. -Higher feed grade to the flotation plant. -Reduction in capital and operating costs (i.e. smaller plant, lower power requirements) -Shares at 0951 GMT up 0.02 pence, or 2.16%, at 0.71 pence. -By Zechariah Hemans, Dow Jones Newswires; 44-20-7842-9411; [email protected] (END) Dow Jones Newswires June 18, 2010 05:54 ET (09:54 GMT)
