Blanket Gold Mines started production records since 1904 - Early workers tended to mine the visible gold sections of the pay shoots, i.e. pick the "eyes" out of the mine. Significant early production milestones were: in 1965 Falconbridge acquired the property and increased gold production to an average of approximately 45 kg per month; in 1993 Kinross took over the property and built an enlarged Carbon-in-Leach ("CIL") plant with capacity of approximately 3,800 tonnes per day ("tpd") to treat an old tailings dump together with the run-of-mine ore.
Gold production reached a level of 110 kg per month during the tailings treatment years from 1995 to 2007. Falconbridge and Kinross invested more than $100 million in development cost and its about $200 million in the current fiat currencies - To date in excess of 1 million ounces of gold have been produced from the property.
On April 1, 2006 a wholly-owned subsidiary of Caledonia Mining Corporation completed the purchase of the Blanket Mine from Kinross. Caledonia has allowed Blanket to make considerable capital investments in its underground, surface and township facilities.
These investments culminated in the commissioning of the No 4 Shaft Expansion Project at the end of September 2010 which has increased Blanket's underground production capacity from 500 tonnes per day to over 1,000 tonnes per day thereby increasing gold production capacity from 24,000 ounces per annum to approximately 40,000 per annum by the end of Q4 2010.
Note. an enlarged Carbon-in-Leach ("CIL") mill plant with capacity of approximately 3,800 tonnes per day ("tpd") to treat the run-of-mine ore. The Gold Mine at current 1000 tpd - produce Au 40,000 oz - The Blanket Gold Mine CIL has the capacity to produce the target Au 100.000 oz and more without the large capital investments to the mill etc.
The other old mines underground workings start to be re-activated for more gold ore to the CIL mill -
Note. the bottom line!

New headgear, winders and winder house and compressor installed for the purpose of sinking a new shaft down to Level 4 (approx. 150m below surface) - the old GOLD mines workings being re-commissioned :-)
