April 8, 2013 (Source: Lincoln Minerals) — Lincoln Minerals Limited (“LML”) is pleased to announce it has completed a full scale and supportive Scoping Study on developing a Pilot Plant to produce for customer assessment, product from its Indicated and Inferred Mineral Resources at the wholly owned Kookaburra Gully graphite project on South Australia’s Eyre Peninsula.

Pilot Plant Summary

The Pilot Plant Scoping Study was prepared by David Salari (P.Eng.) of D.E.N.M. (Engineering) Ltd and examined the development of a pilot graphite processing plant on southern Eyre Peninsula.D.E.N.M was previously involved in engineering design and planning for a proposed rebuild and upgrade of the existing 20 tonnes per hour process plant at Uley Graphite Mine.

The supported design of a modular graphite pilot plant for the Kookaburra Gully Project has anoperating throughput of up to two (2) metric tonnes of feed material per hour to produce a range of graphite concentrate products at a rate of 0.283 metric tonnes of product per hour (2.26 tonnes per 8- hour shift). The pilot processing system features crushing, screening, milling, flotation and dewatering circuits across primary, secondary and tertiary stages of processing. All ancillary equipment has been addressed and includes power generation, electrical components including lighting, internal piping, a water distribution system and flotation reagent distribution.

The modular construction of the pilot plant anticipates construction on three (3) semi-trailer sizeplatforms, T1 to T3 (Figure 1), which could be easily mobilised from Adelaide and demobilised following completion of pilot plant processing trials.

This mobile system will minimise total project time and cost by maximising the amount of construction work completed under a controlled environment (Adelaide) and minimising installation and commissioning time at the proposed Kookaburra Gully processing site. The mobile system is designed as a “plug and play” facility.

This mobile pilot plant will allow Lincoln to process run-of-mine material to test and confirm metallurgical characteristics of the feed material for an optimal final process flow sheet. It will also produce a final graphite concentrate product and sufficient sample quantities for market and customer consideration in Australia and internationally.

The Pilot Plant Scoping Study includes the process design criteria, capital cost summary, equipment details and the mobile process flow diagram. The previous study “Kookaburra Gully Graphite Project – Infrastructure Scoping Study October 2012 – Parsons Brinkerhoff” was utilised as a reference for the pilot plant determinations. Adjustments were required to allow for the smaller pilot size equipment in terms of feed size to the plant.

The Pilot Plant Scoping Study has been prepared to provide Lincoln with cost estimates for the immediate engineering, design, procurement, construction and management (EPCM) of the completed delivery of a pilot plant within a project conservative timetable from start to finish of 24 weeks. The Pilot Plant Scoping Study addressed the following components in providing estimates:

  • Primary processing plant (initial crushing and washing of ore)
  • Secondary processing plant (secondary milling and flotation of ore)
  • Tertiary processing plant (regrinding, flotation, screening and drying of concentrate for bagging)
  • Pilot plant construction, mobilisation and commissioning
  • Master control circuit (MCC) and electrical systems including power supply.
