Freda Rebecca Gold Mine
A total of 8,577 ounces ('ozs') of fine gold were dispatched during the quarter ending March 2011. This represents an improvement of 10.7% on the previous quarter (7,747ozs).
Freda Rebecca Quarterly Operational Indicators | |||
January 2011 | February 2011 | March 2011 | |
Tonnes Mined (t) | 44,005 | 57,728 | 62,803 |
Tonnes Milled (t) | 44,505 | 42,293 | 54,925 |
Head Grade (g/t) | 2.33 | 2.38 | 2.69 |
Recovery (%) | 86 | 84 | 82 |
Gold ounces produced (oz) | 2,879 | 2,125 | 3,573 |
Since the recommencement of operations in September 2009, production tonnage, grade and recovery have made steady progress. Ramp-up to the Phase 1 annualised production target rate of 2,500 oz per month (30,000 ozs per annum) has been successfully achieved and the average monthly production rate exceeded that target in the quarter to March 2011. Phase 2 development to expand production to 50,000 oz per annum is well advanced.
A steady increase in mined tonnage from underground operations has been recorded. This is attributable to improved loader availability and the deployment of an increased number of trucking units, following the award of a load and haul contract as part of the ramp-up strategy for Phase 2.
Operational effectiveness as measured by equipment availability, running hours, and tonnes per hour have demonstrated that the milling circuit is well established and capable of handling the required volume throughputs. As a result of implementing the planned maintenance programme, involving significant upgrade work on the processing plant, plant availability has improved and has been sustained ahead of targets.
Plant recovery has improved progressively since operations resumed, with an average recovery rate of 84% being achieved during the last quarter.
As a result of these improvements, gold production has shown steady progress over the year, culminating in 3,573ozs of gold being dispatched in March 2011.
With effect from the 11th of January, Freda Rebecca joined the "uninterrupted power supply" tariff with Zimbabwe Electricity Supply Authority. Since that date, the site has benefitted from full power with no incidents of load shedding or power disturbance being recorded.
Phase 2 development at Freda Rebecca continues with the refurbishment and commissioning of the second mill planned for the second quarter of 2011. Once commissioning of the second mill has been completed, further improvements will be retro-fitted to the existing Mill 1 circuit in order to improve recoveries by optimising mill speed, liner configuration and associated liner wear issues. Once this work has been completed, the Phase 2 annualised production target rate of 50,000oz per annum (4,167 oz per month) is expected to be achieved towards the end of the third quarter of 2011.
In February 2011, following fulfilment of the required conditions, including the provision by the Export Credit Insurance Corporation of South Africa ("ECIC") of political risk insurance for the facility, Freda Rebecca drew down the first $4m tranche of a $10m project finance facility from the Industrial Development Corporation of South Africa Ltd.
In April 2011, the Company announced increased mineral resources at Freda Rebecca. Based on a cut-off grade of 1.5g/t gold, the Indicated Mineral Resource increased from just over 1 million ounces to 1.67 million ounces of gold while the Inferred Mineral Resource, as similarly defined, is now 0.64 million ounces.
Freda Rebecca Gold Resource* | |||
Tonnage (t) | Grade Au (g/t) | Gold ounces | |
Indicated | 21,043,261 | 2.48 | 1,675,195 |
Inferred | 8,746,114 | 2.28 | 639,719 |
Effective Date: September 2010; JORC compliant gold resource at 1.5g/t cut-off
* 100% Mwana Africa, with commitment to sell 15% to local partner
This increased resource is expected to form the basis of an extended life of mine at Freda Rebecca. The updated mineral resource has been independently verified by SRK Consulting (UK) Limited.
The Company will conduct limited exploration drilling of near mine surface potential on the existing mining permit with the objective of identifying further resources to expand production beyond the Phase 2 target, and, to reduce unit costs.

Bindura Nickel Corporation
The BNC assets remained on care and maintenance for the quarter ending 31 March 2011 and this programme continues to successfully maintain the integrity of the BNC assets. BNC has continued to sell in process inventory and dispose of quoted shares to raise cash. This has enabled the corporation to meet the costs to date of the care and maintenance programme, Trojan pre-start activities and partial payment of balances owed to creditors from own resources.
Given the recent recovery in the Nickel price and the improvement in operating conditions in Zimbabwe, management is seeking to recommence BNC mining operations in a phased manner. The first phase will be to restart the Trojan mine and to sell Nickel in concentrate. BNC announced in February 2011 that it had signed an offtake agreement with Glencore International who will purchase the concentrate produced by Trojan. BNC continues to seek finance to fund the restart of operations.
Trojan Mine
In anticipation of the re-start of operations management has carried out a program of works aimed at overhauling key components of engineering and operational infrastructure. These works, funded from the BNC balance sheet, included overhaul of the main pumping arrangements and ventilation fans and a replacement programme of shaft guides. On surface the waste handling system has been re-engineered together with a major overhaul of the surface secondary and tertiary crushers.
Preparatory work for the restart of operations has included the commencement of limited underground development (approximately 500m development completed) allowing the commissioning of underground Load Haul Dumpers, rigs and associated mining and engineering services together with shaft systems. Ore and waste hoisted to surface has allowed the successful hot commissioning of the surface waste conveyors and ore crushing facilities. The objective of the program has been to de-risk the planned restart program in anticipation of project funding. The management team at BNC has been retained during care and maintenance and have been re-mobilised and actively engaged in the pre-start program.

Klipspringer Diamond Mine
2,616 t were mined and 745 were carats recovered in January at the Klipspringer Diamond Mine, of which Mwana owns an equity stake of approximately 65%. Following a number of severe weather incidents in December and January, which flooded the shaft bottom and lower (7) level, a decision to stop production and development at Klipspringer for reasons of health and safety was taken.
Operations have ceased and the mine is currently in a recovery phase aimed at re-instating infrastructure that was damaged as a result of the flooding. Management are reviewing restart scenarios and timing.

Zani-Kodo JV
The most recent resource update for Zani Kodo in July 2010 outlined JORC compliant resources (at 1 g/t cut-off) of:
Zani Kodo Gold Resource | Attributable ounces (80%) | |||
Tonnage (t) | GradeAu (g/t) | Gold ounces | ||
Indicated | 2,480,351 | 3.21 | 255,916 | 204,733 |
Inferred | 8,577,859 | 3.62 | 997,850 | 798,280 |
Effective Date: July 2010; JORC compliant gold resource at 1g/t cut-off
During the quarter drilling was focused on the Badolite target, 1.5km to the south of the Kodo Main deposit (Figure 1). Two diamond rigs were active and a total of 17 holes for 3,826m were completed. All holes were drilled vertically.
The drilling accurately intersected the southern continuation of the mineralised trend which is marked by the easterly dipping lithological contact between footwall metagreywacke and Banded-Iron Formations with minor black shales. The contact in this area is not exposed, being covered by transported talus material.
All the intersections at a 1g/t cut off average received during the quarter are shown below:
HOLE ID | Depth From (m) | Depth To (m) | m | Au g/t |
BDLDD020 | 108.0 | 117.4 | 9.4 | 1.39 |
BDLDD023 | 272.0 | 285.0 | 13.0 | 1.82 |
BDLDD031 | 261.6 | 264.0 | 2.4 | 1.60 |
BDLDD031 | 265.5 | 266.0 | 0.5 | 1.13 |
BDLDD032 | 299.0 | 306.1 | 7.1 | 2.81 |
BDLDD033 | 333.0 | 341.0 | 8.0 | 3.33 |
BDLDD022 | 229.5 | 234.0 | 4.5 | 2.22 |
BDLDD024 | 45 | 48 | 3.0 | 2.14 |
BDLDD024 | 56 | 62 | 6.0 | 3.43 |
BDLDD024 | 72 | 77 | 5.0 | 3.55 |
The location of all the results at a 1g/t cut off average to date at Badolite is shown in Figure 2.
The Directors believe that the drilling results are encouraging and indicate the following:
·; Confirmation of the geological model with drilling carried out in a "blind" area beneath talus cover and accurately intersecting the mineralized horizon as predicted;
·; The presence of continuous mineralization over a strike length of 500m;
·; Mineralisation remains open along strike and at depth;
·; The presence of two high grade shoots within the overall zone. These plunge to North-Northeast in a similar fashion to those already identified at Kodo Main to the north;
·; Mineralisation is near surface and oxidized to a maximum depth of 60m.

Katanga Concessions (SEMHKAT)
No drilling has been carried out in the SEMHKAT properties during this quarter due to seasonal rains.
Exploration activity has focused on the following:
·; Updating of database;
·; Compilation of recent exploration results;
·; Planning of future exploration programmes;
·; Preparation of equipment and access routes for upcoming programmes.
The final set of assay results from drilling on the Kibolwe West area were received (Figure 3). A summary of all the intersections above a 0.5% Cu grade is shown below:
HOLE ID | FROM | TO | Width (m) | Cu GRADE (%) |
KIBWDD14B | 18.0 | 42.5 | 24.5 | 1.12 |
KIBWDD14C | 10.8 | 13.0 | 2.25 | 0.75 |
KIBWDD009 | 110 | 130.0 | 20 | 0.88 |
133.0 | 154.0 | 21.0 | 0.8 | |
215.0 | 223.0 | 8.0 | 0.62 | |
KIBWDD010 | 40.9 | 84.4 | 38.5 | 0.86 |
KIBWDD011 | 20.9 | 35.9 | 15.0 | 0.65 |
117.0 | 132 | 13.6 | 0.92 | |
135 | 142 | 7.35 | 0.62 | |
KIBWDD08 | 141.85 | 147 | 3.15 | 1.18 |
208 | 227 | 19 | 0.69 | |
KIBWDD10B | 52 | 55 | 3 | 0.54 |
KIBWDD12 | 18 | 70 | 52 | 0.62 |
76.9 | 80.4 | 3.5 | 0.88 | |
88.05 | 92 | 3.95 | 0.85 | |
KIBWDD16C | 102 | 116 | 14 | 0.75 |
KIBWDD17B | 67 | 75.92 | 7.92 | 0.71 |
The assay results indicate the following:
·; Mineralisation splits into two discrete zones, consistent with the limbs of an easterly plunging anticline, the crestal area of which hosts the main Kibolwe mineralization.
·; Cu grades drop off towards the west
·; No further drilling is currently planned on the western extension.
