Freda Rebecca Gold Mine

Full name:
Freda Rebecca Gold Mine (FRGM)
The gold mine is situated near the town of Bindura, some 90km north-east of Harare, Zimbabwe.
Mwana interest:
Mwana owns 85% of FRGM.
Geology and history:
FRGM lies on the central axis of the synclinal Mazowe-Bindura Greenstone belt. The geology of the area around FRGM is characterised by the Shamvaian sediments, diorite and granodiorite. The FRGM orebodies are largely hosted by the Prince of Wales diorite and the Bindura granodiorite. The mineralisation is hosted within two major shear envelopes. Individual shears are variable in width and these two systems merge to the south west at depth flattening at around 850m elevation and extending into the metasediments. The shear system is characterised by a set of anastomosing shears separated by relatively underformed rock units.
The exploration, development and production history for gold in the Bindura area dates from 1912. The Freda oxide and the Freda and Rebecca sulphide gold deposits were discovered in 1987. Mine development commenced under Cluff resources by two open pits removing oxides at Freda and sulphides at Rebecca. The first gold pour took place in 1988. Ashanti Goldfields Zimbabwe acquired the mine in 1996. Underground operations commenced at the Rebecca section in 1996. In 1998, the Freda pit was depleted and the Freda Rebecca Mine became a fully underground operation.
FRGM operated continuously for more than 17 years from 1988 to 2007. FRGM operations were put on care and maintenance in March 2007 due to adverse economic and operating conditions in Zimbabwe. Operations were then restarted in 2009.
Today, FRGM comprises a shallow underground operation, currently mining at a depth of circa 200m and processes ore through a single facility utilising a combination of crushing, conventional sag milling, combined gravity and CIL process, electro-winning and bullion smelting.
Current status and prospects:
Following the introduction in Zimbabwe of a number of proactive economic policies in early 2009, including, the dollarization of the economy, the review of gold marketing conditions to allow export of gold, and, the permission to remit proceeds of sales in foreign currency. These changes together with an improved gold price allowed Mwana Africa to embark on a two-phased programme to bring the mine back into production.
The first phase of this programme, including re-capitalisation of the mining fleet and refurbishment of one of the two mills, brought FRGM back into production targeting a production rate of 2,500 oz per month (30,000 oz per annum). Gold production at FRGM re-commenced in October 2009, and the production for the financial year to 31 March 2011 was 27,240 oz of gold, with 3,574 oz of gold produced in the month of March 2011.
The second phase of the programme included refurbishment of the second mill and expansion of the leach circuit. In June 2011, the Company announced that the Phase 2 construction programme was completed with Mill 2 being successfully commissioned on time and within budget. Production for the financial year to 31 March 2012 was 47,770 oz of gold.
The focus is now an improving mining and processing efficiencies to increase throughput and improve recoveries and thus increasing gold production.
