RioZim Limited has floated a tender, seeking bids for contract mining at its Cam and Motor gold mine in Kadoma. “Tenders are invited from suitable and interested bidders from suitable and interested bidders for the provision of contract at the Cam and Motor Open Cast Mine. Prospective bidders should have capacity to mine 270 000 tonnes per month,” RioZim said in a statement.

The multi-commodity miner said the work put to tender included the open cast mining sequence of clearing, drilling and blasting, overburden mining clearing, drilling and blasting of ore and ore mining.

Ancillary activities related to the sub-contracted work include haulage road maintenance, dust suppression, drilling to probe for old workings as well ground support.

The Cam and Motor Mine is situated 130 kilometres south west of Harare, about 10km to the east of Kadoma.

The mine was once the largest producer of gold in Zimbabwe and produced over 150 tonnes of gold in its entire life.

Three main ore bodies were mined by the Cam and Motor Gold Mining Company, the previous owners of the mine.

These were the Motor Lode, Cam Lode and Petrol Lode. In 1968, the mine was closed with the gold price at US$35 per ounce and the mine operating at depths of 1 800 metres when operations were no longer viable.

At that stage, the mine cut- off grade was 8 gt and s was considered there could be significant resources adjacent to old workings that would now be economic to mine.

RioZim commissioned an exploration program to search for the expected lower grade zones surrounding the mined ore bodies at the Cam and Motor Mine.

Thus far 65 drill holes totaling 7 000m over two phases have been drilled, phase one drilling programme totaling 2 775 m was drilled between February 2009 and July 2009, focusing on the Motor Section.

RioZim said from this drilling, a resource totaling 1 290 744 tonnes at a grade of 4,26gt gold with 171,543 contained ounces has so far been determined.

Phase two drilling programme has been undertaken on the Cam Lode in which 16 holes totaling 1 767 meters were drilled.

By the end of March 2010, the resource indication was about 3 500 000 open pittable tonnes at a grade of 4,5gt yielding 500 ,000 ounces delineated to a depth of 100 metres on the Motor, Cam and Petrol ore bodies.

A deep drilling programme was commenced in April 2010 to determine resources between 100 and 400 metre depth.

The new Cam and Motor facility will be opened in August 2014 with projected monthly production of 4 000 ounces.
