NTL - Progress under the Radar - Is it the next Disallowed?, page-59

Hi Bizzo. Appreciate your questioning this. I'm no miner, but NTL's says this:

in 2013 NTL commissioned a Pre-Feasibility Study on the Talisman Mine. The Pre-Feasibility Study analysed a range of options around the mining method, materials handling and backup services with a view to identifying the preferred option to establishing a low impact, small-scale underground mining operation. The operation will focus on the high confidence resources, immediately adjacent to the accessible 8 Level drives, delineated during the 2005 exploration program, and create the infrastructure necessary to support further exploration activity. Key findings from the study were:
Mining Method – Ore veins are steeply dipping, from 70° to near vertical, with widths ranging from ~1.0m in the Welcome/Crown area to >6.0m in the Woodstock. Preliminary stope designs were constructed encompassing the volume of estimated payable ore in each resource block. Analysis indicates that the geometry of the lodes is potentially suitable for a number of mining methods. The study recommended that a sub-level stoping design be implemented to provide the flexibility to switch between hand-held and long-hole drilling techniques where applicable.
Materials Handling – An option analysis was carried out on the installation of rail bound transport systems underground compared with the deployment of a fleet of small, rubber tyred loaders and trucks. Results clearly demonstrated that the flexibility of a trackless fleet, which would enable extraction of the resources below 8 Level through a series of small ramp systems, held significant advantage to the project.
Production Plan – A production plan was developed based on the above assumptions. It indicated that an initial five-year operation, with peak production of 35,000 tonnes per annum and 12,000 gold ounces in years 3 and 4 was possible. 65% of the total 106,000 tonnes mined would be derived from the better understood Woodstock and Dubbo Sections. Production planned from the Mystery and Welcome/Crown blocks would primarily comprise on-reef development required to improve and extend the confidence of resource estimates within these areas.

I recall there was also talk about using a "Concentrator" to reduce material handling. Not sure how this fits in or where but perhaps you can comment. Thanks
