Succeeding the commencement of dispensation kimberlite ore in nighttime November 2011, the 500tph Stage 1 vegetable was specially made on 31 December 2011. During this retro 6,500 tonnes of predominately K6 kimberlite ore were processed for the retrieval of 1,080 carats. In addition, 425 carats, at an normal stone size of 0.1 to 0.2 carats per grit were healthier throughout the training of shape sorters, on or after previously fixed recovery followings.Cutting-edge the dated after 1 January 2012 to 25 February 2012, 303,814 tonnes of predominately KOther ore must remained administered for the recapture of 25,546 carats at an average mark of 8.41cpht and an regular nugget extent of 0.24 carats per stone. The coalfield willpower change addicted to Chapter 1 commercial production, in-line with the rations of the mining covenant thru the Government of Lesotho, on 1 Hike 2012.
11 rhombi in excess of 10.8 carats (with a joint weight of 245 carats) must be situated healthier in this ramp-up phase, including an 82 carat dodecahedron, awarding a yellow/brown hue by few enclosures. This accompaniments a number of minor elaborate and creamy elaborate rhombuses well again to-date from the Kao Mine throughout its expansion chapter and demonstrates a potential for specific fat and elaborate pebbles.
The ramp-up to Stage 1 saleable construction has proved that typical lozenge grades, once generalized beginning production results, endure in-line by folks accomplished through the metallurgical exam work led in 2010 / 2011 (K6 at 18cpht and K-Other at 6.24cpht). Furthermore, regular pebble extents are in-line through forecasts ended for the 500tph meting out shrub in its current metallurgical setup and the fees attained for such rhombuses are in-line with hope for such mesh magnitudes. Separately, ongoing ore physique description has recognized added kimberlite facies, which greasepaint the Kao Chief Cylinder Multipart (KMPC) and, as a result, the environmental model and controlled resource have been refined to offer a 189Mt kimberlte supply of c.12.8m carats (c.4m indicated and c.8.8m inferred), with an extra 1.7m carats at a bond equal of self-confidence.
To-date, the mix of advanced mark K6 ore to minor score K-Other ore handled has only be situated 1:5 due to shortcomings through the minor overwhelming capacity, which has incomplete (and at periods prevented) the severe of high rating K6 ore since the novel idea of a 1:3 percentage among K6 and K-Other.
To steadfastness this problem, the Business plans to mount two new cone crushers: one to replace the two prevailing lesser crushers; and one to growth dimensions in the tertiary devastating circuit, by employed in parallel through the current existing grinder. These spare pounders are expected to price c.US$2m in whole and resolve be brought and fit through an 8 - 12 week timeframe. Thereafter, these rods must permit for the optimal and dependable processing of hardrock kimberlite minerals.
The lake stowing dam is almost complete and it is predictable to be full to size formerly the dry period originates in May, to provide a enough source of water for the nonstop act of the 500tph giving out herbal. The new, municipal of the art category community is actuality custom-built and willpower offer amplified equilateral cataloging bulk and upgraded security.
Since December 2009, Namakwa Rhombi has expended c.US$69.5m on the progress of the Kao Coalface. The Corporation imagines to endowment further money foods since the remaining headroom on the US$40m business facility with Jarvirne Imperfect ("Jarvirne") and the working moneys movements of the Kao Pit.As per a outcome of the matters bump into thru the minor devastating bulk during the ramp-up to Phase 1 marketable production and the controlled capacity to process from head to foot grade K6 hardrock ore, composed through the additional capital outflow requirements for the two new crushing units, the Kao Pit is now expected to converted net coins drift constructive in Q2:CY'12, rather than Q1:CY'12, as beforehand proclaimed. However, the new rods are expected to upsurge subordinate and tertiary overwhelming bulk on or after the present levels to 250tph throughout the secondhalf of the Company's economic year, agreeing direction to keep on unaffected at 200Kcts for FY2012.By means of at 25 February 2012, 11,245 carats had stayed wholesaled on caring in Johannesburg at an typical value of US$237.60/ct. A additional 7,200 carats are presently on fond and another 8,400 carats obligate been disseminated for tender in first Trudge 2012.Northern West Province, South Africa
As at 25 February 2012, the sandy processes in the Arctic West Sphere had processed 1,508,223 tonnes, manufacturing 10,994 carats, by means of an average ranking of 0.73cpht, in streak by the construction campaigns. This is a noteworthy achievement for the active team, succeeding a significant restructuring of operations, labour contests and an indefinite employed situation. Processes endure to be rationalised as budgets are concentrated but management remnants unaffected at 20Kcts for FY2012.
