Noventa Limited ("Noventa" or the "Company") - Update on Interim Comminution Circuit & Exploration Activity

TORONTO, April 5 /CNW/ - Interim Comminution Circuit

Further to its recent announcement on 18 February 2011, Noventa is pleased to announce that following an intense period of commissioning and testing of the Interim Comminution Circuit ("ICC") and the introduction of its new fleet of mobile equipment, production of tantalum concentrate at the Company's Marropino Mine has increased from its previous annual rate of 50,000 lbs to circa 200,000 lbs contained tantalum per annum ("p.a."), bringing the Company closer to cash flow break-even.

During testing and commissioning a few problems occurred, which were generally due to wear and tear on the existing old plant rather than the ICC; as a consequence, management have taken the opportunity of scheduled commissioning shutdowns to replace key components, for example the plant's static grizzly (a screen that prevents oversized rocks entering the circuit), before they fail.  This is in line with the Company's maintenance philosophy of preventative maintenance since recommencing operations in April 2010, which has ensured the plant has retained its availability, which at 95%, is ahead of expectations.  Recovery remains at circa 52%.

The ICC will remain in place until the new process plant is complete later this year, after which it will be reconfigured to form the new plant's "recirculation circuit", contributing to full production of over 600,000 lbs contained tantalum p.a., expected during the last quarter of 2011.


Further to the announcement made on 17 January 2011, the following progress has been made as regards the Company's exploration activities at its Marropino property:

  • Marropino South - 15 trenches were excavated by 23 March 2011, and samples are being prepared for analysis.  Some re-sampling is due to take place due to damage to trenches as a result of very heavy rain.  The samples will be despatched from Marropino by 11 April 2011.
  • Marropino South Pegmatite - Drilling of the Marropino South pegmatite began on 4 April 2011, with 6 sampling holes due to be drilled by the end of April 2011.  Samples from the first 3 of these holes will be despatched from Marropino in mid April.
  • The Existing Marropino Pegmatite Extension - Drilling of the pegmatite core commenced on 16 March 2011.  9 holes have been drilled and completed by 1 April 2011, and sample preparation has commenced.  Samples are due to be despatched from Marropino as soon as possible.

All the above results should be available around the end of the second quarter 2011.

Chairman, Mr. Eric Kohn TD, commented, "Another key milestone has been achieved on the route to full production.   Our main focus is now the construction and commissioning of the new plant which is on schedule and will allow us to achieve the production circa 600,000 lbs p.a. of contained tantalum by the end of quarter 4 of this year, as well as the operational development of the wider Marropino concession and our other concessions at Morrua and Mutala in line with our strategy".
