Caledonia doubles production at Blanket mine

Caledonia’s Blanket
gold mine in Zimbabwe
Toronto, Canada —MININGREVIEW.COM — 27 January 2012 – Canadian-registered and African-focused Caledonia Mining Corporation has announced a successful year in 2011 at its Blanket Mine in Zimbabwe, with production of 35,826oz of gold “’ an increase of 102% over the previous year.

In a statement released here, Caledonia said it was now confident that it would be able to achieve its targeted gold production of 40,000oz for the current financial year. Discussions with the government of Zimbabwe regarding the indigenisation of the Blanket Mine have continued, it added.

The statement went on to say that, in accordance with the company’s aim to continuously improve operations at its Blanket mine “’ 150 km south-west of Bulawayo “’ the following infrastructure, process and equipment investment programmes had been undertaken during the final quarter of 2011:

Considerable work on the refurbishment of the 14, 18 and 22 Level underground haulages continued throughout Q4 and this is expected to be completed by the end of Q1 2012. This programme is essential to support and sustain increased underground production.

The installation of an automatic cyanide measuring and dosing system on the CIL circuit was commissioned. This installation is providing both better control over, and a detectable reduction in, cyanide usage per tonne of ore milled.

Certain rectification and maintenance work on the 825m deep No4 Shaft was commenced during November 2011. This work is expected to be completed by the end of February 2012, and once completed will allow Blanket to increase the speed of the No4 Shaft winder, thereby increasing hoisting capacity. As noted in the Q3 MD&A, this work may have an adverse effect on gold production in the first quarter of 2012.
A belt scale was installed on the No1 Conveyor Belt so that all ore tonnages delivered from various ore sources such as the 14 Level mid-shaft loading station, Lima “’ and in due course the satellite properties such as GG and Mascot “’ can be individually and accurately measured. The re-programmed computerised recording system is expected to be commissioned during early February and the system is then expected to facilitate further metallurgical optimisation.
