Luishia Mine
Encyclopedia
Luishia mine was an open pit copper and cobalt mine in Katanga Province
, Democratic Republic of the Congo.
A concession to the south of the mine has recently been opened to exploitation.
.
In October 1928 the mine employed 1,466 men. That month there were two deaths, and 16.37% of the men fell ill.
The mine was hit by arson and sabotage in 1938 by miners dissatisfied with their pay and working conditions.
In December 1941 the miners, and those in other mines in the area, began a general strike.
While the open pit mine was in operation a total of 4.1 million tonnes of ore were extracted with an average grade of 8.3% copper.
There was a defined total resource of 26.1 million tonnes of ore with average grades of 2.95% copper and 0.68% cobalt.
The review considered it would be practical to produce 3,000 tonnes of ore per day ore using large-scale open cut mining.
As of 2008 the main Luishi orebody was controlled by a consortium owned by Chinese and local investors.
Compagnie Miniere du Sud Katanga (CMSK), owned 60% by Enterprise Générale Malta Forrest, a subsidiary of Groupe Forrest International and 40% by Gecamines
, had exploitation rights in the zone, which as of 2011 were in the exploration phase.
CMSK's main operation was at the Luiswishi Mine

and covers an area of 16.2 square kilometres (6.3 sq mi).
It lies to the south of the main Luishi orebody.
The Kipoi
copper / cobalt exploration project of Tiger Resources
lies to the southeast.
Luisha South includes a small historical open pit mine and waste rock pile, as well as the underlying Roan group sediments assumed to hold major deposits of copper and cobalt.
The Luisha South ore was explored between 1923 and 1928 through shafts and tunnels, finding that there was about 350,000 tonnes of ore at 8.6% copper.
Most of this was later mined in a small open pit. Since closure, artisanal miners have continued to work the site sporadically.
The pit is in the northwest corner of the property at coordinates 11.178886°S 27.016658°E.
A permit to exploit the project was issued in March 2006.
Chevalier Resources acquired 57% of the project. In November 209 African Metals Corporation
announced a binding letter of intent to buy Chevalier.
In June 2011 African Metals gave an initial estimate for its Luisha South Stockpile.
There was an inferred 370,000 tonnes of ore at 1.0% copper and 0.5% cobalt.
In August 2011 the company issued an updated estimate for the project as a whole.
There was an inferred 14.7 million tonnes of ore at 1.1% copper and 0.3% cobalt, giving 161,700 tonnes of contained copper metal and
44,100 tonnes of contained cobalt metal.
In September 2011 African Metals said a subsidiary had purchased a Dense Media Separation plant and other equipment in preparation for mining.

Later exploitation plans
A 2007 assessment of the main Luishia mining permit noted that it included about 1729 square kilometres (667.6 sq mi) over most of the mine and resource development area, including the existing and planned mining pit. China Overseas Engineering Co. Ltd held 72% with the balance of 28% held by a Gecamines subsidiary.There was a defined total resource of 26.1 million tonnes of ore with average grades of 2.95% copper and 0.68% cobalt.
