why hasnt drilling started yet, page-293

...."Manganese ore was produced primarily by small-scale operations near Mansa in Luapula Province and Mkushi in Central Province. Domestic subsidiaries of international companies that were involved in the small-scale manganese ore operations included Ore and Steel Feed Industries, which was a subsidiary of Contrarian Investment Holdings (Proprietary) Ltd. of South Africa; Peniel Mines, which was a subsidiary of MGR Commodities and Gems of South Africa; Taurian Manganese Ltd., which was a subsidiary of Dharni Sampda Private Ltd. of India; and the joint venture of Genesis Procurement Ltd. and Luapula Base Metals Ltd. Taurian started mining ore near Mansa in 2011. Taurian also proposed to build a 240,000-t/yr-capacity ferromanganese plant near Mansa in 2012 and to expand the plant’s capacity to 720,000 t/yr by 2014. Manganese traders included San He Zambia Ltd., which exported high-carbon ferromanganese (Thomson Reuters, 2011).
Allegra Mining Zambia Ltd., which was a subsidiary of Ethan Minerals Ltd. of Australia, dissolved its Mkushi area exploration joint venture (Kafwa project) with Eagle Eye Mining Ltd. of Zambia in 2010. Allegra entered into numerous other joint ventures with companies and individuals that held manganese mining and prospecting licenses. Properties included the Kampumba Mine, from which illegal mining operations recently had produced an estimated 650,000 t/yr of manganese ore at an average grade range of 50% to 61% manganese. Allegra proposed to mechanize the operations at the Kampumba Mine. In mid-2011, however, financial difficulties forced Ethan Minerals to appoint external Administrators to take control of the company. The Administrators established a Creditors’ Trust and transferred Ethan’s 100% equity interest in Allegra Mining to the Creditors’ Trust for disposal (Ethan Minerals Ltd., 2010, 2011; Prospect Resources Ltd., 2012, p. 22).
Atticus Resources Ltd. of Australia initiated the acquisition of Zamanco Holdings Ltd. of Mauritius. Zamanco held two Zambian companies—Zamanco Minerals Ltd. (100% equity interest) and Zamanone Mining Ltd. (75% interest). Zamanco had proposed to develop the Serenje manganese project, which included an 180,000-t/yr-capacity manganese concentrate facility, three smelters with a total production capacity of 60,000 t/yr of high-carbon ferromanganese (with an expected average 78% manganese content), and a 12,000-t/yr-capacity"......

That is the extract you are misquoting Santoo2 - Kindly note the ILLEGAL operations detail associated with Kampumbe that had by some miracle a 650,000 ton per annum operation and the subsquent Administration following a mechanised mining proposal.... ONLY IN AFRICA would you fhatom an ILLEGAL GHOST operation at 650ktpa that still manages to loose money without even paying royalties or anything to that effect, wonder how they transported that much dirt undetected...maybe via Ogies onwards to Richardsbay or something like that

Then;

In the table on Page 7 of 9 under the Commodity heading Manganese:

Gross Weight - 120,000 tonnes

Mn Content - 40,000 tonnes

Looks roughly like 33.3333% to me but can you clarify whether that calculation is correct though? Seems those grades might get diluted somewhere though

Do your research you will need it if you wish to venture here with your hard earned in my opinion
