OUTLOOK
In keeping with the Company's oxide strategy, Banro has developed several key objectives for 2013 to increase gold production while containing costs, thereby increasing shareholder value. These objectives include:
The Company's capital expenditure forecast for 2013 as compared to 2012 is set out below:
TWANGIZA MINE
Effective September 1, 2012, commercial production was declared at the Twangiza Gold Mine. Management considered several factors in determining commencement of commercial production, including the productive capacity of the mill, substantive completion of the construction, and when the plant would be ready for its intended use. As a result of excessive vibration encountered with the Mill 1 motor and due to CIL tank residence times being lower than ideal, plant throughputs and recoveries remained below design capacity for the eight month period ended August 31, 2012. However, once Mill 1 was brought back into service, and the primary, secondary and tertiary crushing circuits were re-commissioned, throughputs in excess of design were observed, although recoveries remained below design due to deficient CIL tank capacity. At the same time, good recoveries were attained during periods of low throughput, which confirms management's decision to increase CIL tank capacity as part of the plant upgrade exercise currently underway. Furthermore, overall plant performance was affected by a shortage of critical spares inventory for major circuit components, including the existing primary, secondary, and tertiary crushers, as well as the scrubber. Countering this, a major exercise of establishing adequate critical spares inventory is underway, and considerable funds have been budgeted during 2013 to address this.
Mining
A total of 3,014,926 tonnes of material were mined during the year ended December 31, 2012. Total ore mined was 1,731,329 tonnes, which was below management's forecast for the year. Lower than forecast pit production was mainly due to lack of equipment availability, once again as a result of inadequate spares availability - now being addressed as described above - and as a result of the impact of high rainfall. The experience gained during 2012 of the impact of weather conditions has been countered by the sheeting of primary haul routes with crushed rock of suitable characteristics, and advantage will be taken during 2013's short dry season to further improve the quality of haul roads throughout the operation. The stripping ratio for the period was 0.79 against a forecasted ratio of 0.40. This was a function of adjustments to the mining plan in order to optimize grades delivered to the mill during periods of low throughput.
Processing & Engineering
For the year ended December 31, 2012, mill throughputs were 75% of the 1.3Mtpa design capacity, although following the return to service of Mill 1, average mill throughput from September through to December improved to 77.6% of design capacity. However, throughputs comfortably in excess of nameplate capacity of 1.3Mtpa were observed, particularly following the re-commissioning of the primary, secondary and tertiary crushers. All of these crushers will be replaced as part of the plant upgrade exercise currently underway. Recoveries during the year were at an average of 81.7% and a total of 69,687 ounces of gold were produced, which was below management's target for the year. However, recoveries of 90% were periodically observed and the intent will be to approximate these recoveries when throughputs are increased to 1.7Mtpa and beyond as a result of improved residence times following the installation of additional tank capacity.
Twangiza Plant Optimization and Expansion
During the fourth quarter of 2012, work towards upgrading the metallurgical plant commenced, with the goal of improving plant availability, increasing plant throughput, and improving recoveries to approximately 90%. This will essentially entail replacing the existing primary, secondary and tertiary crushers, the building of four new CIL tanks to increase residence time, as well as the upgrading of inter-tank screens and piping, and the construction of a second elution circuit and gold room, all of which are expected to be completed by Q4 2013. It is currently estimated that the capital cost of this plant improvement will be approximately $12,000 in 2013, which is expected to improve plant capacity to 1.7Mtpa.
Sustaining Capital Activities
During the year ended December 31, 2012 and subsequently up to the date of this press release, the following progress was made in the key areas indicated below with respect to sustaining capital activities at the Twangiza Gold Mine:
As of the date of this press release, 230 households have been resettled at the Cinjira relocation site. It is expected that a further 19 households will be compensated and resettled during 2013.
A new fuel storage facility was completed and commissioned at the end of August 2012.
Previously, the maintenance of mobile equipment was conducted at a temporary mobile workshop located 8 kilometres downhill from the Twangiza Main open pit. Management decided to move this facility to a position immediately adjacent to Twangiza Main, thereby eliminating the 16 kilometre round trip to the previous workshop site, and this exercise was completed in November of 2012. In addition, the design of a new warehouse and a permanent mobile workshop were completed in September. These facilities are expected to be constructed and commissioned by the second half of 2013, resulting in a compact and fully integrated mining site.
Construction work associated with the front wall was halted during the dry season, leaving the height of the wall 5 metres below the planned two year elevation. In dry conditions, activity was switched to the downstream side of the wall, where excavation was focused on the removal of alluvial material (of good grade) and the placement of the sand and pipe under-drains to enable the extension of the wall toe to its five year position. This will considerably extend space for waste dumping as the dam wall effectively acts as the single waste dump for the operation. Work towards elevating the wall height recommenced in December 2012.
NAMOYA MINE DEVELOPMENT
The Namoya project consists of one exploitation permit covering an area of 172 square kilometres and is located in the Maniema Province in the east of the DRC, approximately 225 kilometres southwest of the town of Bukavu. The Company is currently developing an open-pit heap leach gold mine at Namoya with anticipated average annual production of 124,000 ounces of gold per annum over a seven year mine life. Pre-construction activities at Namoya began in the fourth quarter of 2011, followed by full mobilization of construction and development activities during 2012. Commissioning of the Namoya gold mine is planned to be completed during the fourth quarter of 2013.
Key Achievements in 2012 and 2013 Outlook
Orders for all long lead mechanical equipment were placed and sea freighting commenced. All earthmoving equipment was delivered to site along with a 120 ton lattice boom crane during Q4 2012. Baraka and Kavumu transit facilities were fully upgraded to better facilitate the inflow of equipment and materials.
Four local construction companies were mobilized for resettlement construction. Resettlement housing construction began and is 75% complete with 72 houses of a total of 207 houses completed thus far. The remaining houses are in various stages of completion. The first 17 households have been resettled into their new houses. Water has been made available to the resettlement area, with installation of supply pipes from the Kibiswa River completed during the last two weeks of 2012. The resettlement process is expected to be completed by the end of the second quarter of 2013.
The main access road to Namoya from Uvira, which spans 420 km in length, is 92% complete. The section from Baraka to Namoya is practically complete with the mountain portion opened up and widened. Eight critical bridges were upgraded and culverts installed during 2012, increasing the logistics capacity of freighting materials and equipment to the Namoya site. Dedicated teams are still deployed on the Uvira-Baraka stretch of the road, which spans 120 km and is expected to be completed during Q2 2013. During this period maintenance work will also be performed on the Baraka-Namoya section, which spans 300 km in length.
Accommodation construction is 85% complete. In the operator's camp, the 5-person houses are completed and occupied by senior staff, while the 12-person dormitory units are 80% complete. The clinic and power supply plant have both been completed and commissioned. Water has been canalized to the operator's camp from the Kibiswa River, with supply pipes installation completed in the latter part of December 2012. Earthworks on the mine village are 90% complete and construction of the mine village is set to begin in the second quarter of 2013 and be completed by Q3 2013.
The engineering design is 98% complete while the earthworks design has been finalized. Earthworks to the plant site is 97% complete. Earthworks in the areas such as the primary crusher, the conveyor belt, the primary product stockpile, and the crushed product stockpile have been completed with civil works currently in progress. Remaining earthwork areas are limited to backfilling of the process plant area to the final terrace level. Construction drawings for the key plant structures have been completed and issued to site. The heap leach pad and ponds are expected to be completed within Q2 2013 at which time mine pit development will commence.
Construction aggregate source has been secured; the crusher/washing/screening plant for providing aggregate to the required size as per specification has been installed and fully commissioned and production of aggregate is on-going.
The construction of the TMF access road is 100% complete and bush clearing of the TMF footprint has commenced. The design of the TMF is complete with all geotechnical work and construction drawings. The TMF will consist of an initial 620,000 cubic metres earth wall at a 12m height with a storage capacity of 2-years of tailings and is expected to be completed during Q2 2013.
As activity increases in and around the development of the Namoya mine site, the recruitment and training of employees continues in order to maintain steady progress of construction. There are currently 1,997 employees on site and it is expected that at peak construction, which will be in Q3 2013, there will be approximately 2,100 employees to help ensure timely completion of the Namoya mine construction and readiness for commissioning in Q4 2013. The Company intends to continue to train personnel and develop appropriate systems in support of the commissioning date and during the operating phase of the Namoya mine.
EXPLORATION
(i) Twangiza Property
The Company's Twangiza property consists of six exploitation permits covering an area of 1,156 square kilometres.
Exploration at Twangiza commenced in October 2005, and has included extensive geological mapping along the 3.5 kilometre long resource delineation of the north trending mining target, which hosts the two principal deposits of Twangiza Main and Twangiza North. The following table summarizes the changes in the Twangiza mineral resource estimates from December 2011 to January 2013:
The current mineral resource estimates for Twangiza are as follows:
The current mineral reserve estimates for Twangiza are as follows:
The 2012 exploration program at Twangiza focused on (a) infill drilling in Twangiza East and West, and (b) further work at Ntula to identify new targets and to enhance the identified mineralization. The 2012 exploration program at Twangiza also involved the commencement of regional exploration in Mufwa and regional target generation programs on the rest of the concession. The goal was for the composite resource model to be optimized and engineered to update the mineral resources and mineral reserves, which was completed in January 2013.
Regional exploration work carried out at Twangiza during the year ended December 31, 2012 focused on the Ntula and Luntukulu prospects. This included auger drilling, trenching and geological mapping in tandem with rock chip/channel sampling and stream sediment sampling. Offsite efforts focused on the interpretation of field data and analytical results, updating of geological maps, and planning of the 2013 exploration program and budget.
During the fourth quarter of 2012, three new trenches and one trench extension totaling 367.50 metres were completed at the Ntula East Zone and the Luhoko Workings. A total of 377 samples were collected. Four trenches totaling 224.00 metres were completed at the Namadava and Colline 1 Workings. A total of 231 samples were collected from these trenches for gold analysis. All trenching efforts were aimed at testing the strike extension of the mineralized zones intersected in previous trenches.
Geological mapping in tandem with rock chip/channel sampling continued during the reporting period in workings within the Ntula, Luntukulu, and Mugugwa areas. The mapping program aims to enhance the understanding of the style of the mineralization and to generate additional targets around the workings. In total 141 rocks chip samples were collected for gold analysis.
During the year, auger drilling was carried out in Lunkuturu within the Namadava soil grid. This was aimed at testing the near surface gold mineralization within soil anomalous zones (greater or equal to 50 ppb). Sixty one (61) auger holes totaling 139.30 m were drilled and 139 samples were generated for Au analysis.
Stream sediment sampling was completed in the area located between the Mufwa and Ntula Prospects aimed at generating soil geochemistry targets. A total of 120 stream sediment samples were collected for gold analysis.
The 2013 exploration program at Twangiza is expected to involve:
The goal is to grow and replace Twangiza's oxide and free-milling reserves utilized in its production process by the end of 2013.
Additional information regarding Twangiza is included in the technical report of SENET dated March 9, 2011 (as revised on March 24, 2011) and entitled "Economic Assessment NI 43-101 Technical Report, Twangiza Phase 1 Gold Project, South Kivu Province, Democratic Republic of the Congo". A copy of this report can be obtained from SEDAR at and from EDGAR at .
(ii) Namoya Project
The Company commenced exploration at Namoya in December 2004. Diamond drill holes have been completed together with extensive re-sampling of old mine adits along the 2.5 kilometre long, northwest trending mineralized zone which hosts the four main separate deposits of Mwendamboko, Muviringu, Kakula and Namoya Summit. Exploration is continuing to assess a number of other prospects, namely Kakula West, Seketi, Kangurube, Matongo and Filon B, all within two kilometres of the four main deposits, to further increase oxide ounces.
The following table summarizes the changes in the Namoya mineral resource estimates from December 2011 to December 2012:
The current mineral resource estimates for Namoya are as follows:
During fiscal 2012 and up to the date of this press release, Namoya's exploration work focused on (a) infill resource diamond drilling at Namoya Summit-Filon B, Namoya Summit extension, Kakula and Mwendamboko, (b) exploration drilling at the Seketi and Kangurube prospects, and (c) trenching and channel mapping and sampling at Mwendamboko. The decrease in total inferred mineral resources at Namoya is due to the conversion of resources from inferred to measured and indicated during the 2012 exploration program.
Field work at Namoya during the fourth quarter of 2012, focused on:
During 2012, 21 exploration diamond drill holes totalling 1,948.41 m were completed at the Filon B, Namoya Summit Filon B, Namoya Summit extension, Namoya Summit and Kangurube prospects. Two drill holes NDD349 and NDD350 were terminated prior to intersecting target due to end of year closure. A total of 2,276 core samples were packed and dispatched for sample preparation and analysis.
A Reverse Circulation (RC) drilling program continued at Namoya during the year and through Q4 2012. The program aimed to sterilize areas proposed for the heap leach pads and the waste rock dump. In addition, the RC rig was used to drill water monitoring boreholes near the proposed plant site and blasting boreholes on the construction aggregates quarry at Kibiswa. A total of 504 RC holes representing 5,306 metres were completed on the proposed heap leach pad, waste rock dump, Kibiswa quarry (blasting holes), and water monitoring wells.
During the year, auger drilling was undertaken at the Kangurube prospect to test the up-dip continuity of the mineralized zones intersected by drill holes NDD333 and NDD318. A total of 13 auger holes were completed along one fence line of 80 m and 64 samples were generated.
Three NE-SW trending trenches were excavated, mapped and sampled at the Muviringu prospect. Trench MVNT35 (32 m long) aimed to test the up-dip continuity to surface of the mineralized zones intersected by the drill hole NDD299. Trench MVNT37 (51 m long) aimed to test the up-dip continuity to surface of mineralized zones intersected by drill hole NDD273. In total, 89 samples representing 87.40 m were generated. A total of 27.60 m of the trenches (10 m of MVNT35, 10 m of MVNT36, and 7.60 m metres of MVNT37) were abandoned after failure to intersect bedrock, even at a depth of 4.2 m due to creeping along slopes.
The Namoya project exploration work program for 2013 is planned to include:
The exploration team will also continue to assist the development team in drilling works related to the construction site investigations.
Additional information with respect to Namoya is contained in the technical report of Venmyn Rand (Pty) Ltd dated January 24, 2012 and entitled "National Instrument 43-101 Independent Technical Report on the Namoya Gold Project, Maniema Province, Democratic Republic of the Congo". A copy of this report can be obtained from SEDAR at and EDGAR at .
(iii) Lugushwa Project
The Lugushwa project consists of three exploitation permits covering an area of 641 square kilometres and is located approximately 150 kilometres southwest of the town of Bukavu in South Kivu Province in the east of the DRC.
The following table summarizes the changes in the Lugushwa mineral resource estimates from December 2011 to December 2012:
The current mineral resource estimates for Lugushwa are as follows:
The results of the 2012 drilling program helped facilitate the conversion of previously inferred resources to indicated levels, while adding further inferred resources. The Company's focus at Lugushwa is on upgrading the inferred mineral resources to higher confidence resources and progressing to the completion of a preliminary economic assessment. An increased amount of metallurgical test work is also planned.
Exploration work during Q4 2012 at Lugushwa, focused on:
Fourteen (14) diamond drill holes (LDD186, and LDD188-LDD200) representing 1,117.30 m of drilling were completed at D18-19 deposit, G7-Mapale, Minkumbu and G8-Kolo prospects. A total of 2,207 core samples equivalent to 2,077.60 m were collected from 23 drill holes (LDD178 to LDD200). A total of 919 core samples from 16 boreholes were collected for relative density measurement.
In addition, 81 auger holes were drilled generating 462 auger samples and total of 14 km lines were covered with IP survey.
Offsite activities focused on geological modelling and grade estimation to upgrade the inferred mineral resources to higher confidence resources, as well as the targeting of higher grade oxides.
The 2013 Lugushwa exploration work program is planned to include:
Additional details with respect to Lugushwa are contained in the technical report of Venmyn Deloitte dated March 15, 2013 and entitled, "Independent National Instrument 43-101 Technical Report on the Lugushwa Gold Project, South Kivu Province, Democratic Republic of the Congo". A copy of this report can be obtained from SEDAR at and EDGAR at .
(iv) Kamituga Project
The Kamituga project consists of three exploitation permits covering an area of 643 square kilometres and is located approximately 100 kilometres southwest of the town of Bukavu in the South Kivu Province in the east of the DRC.
The current mineral resource estimates for Kamituga are as follows:
The Company commenced exploration at Kamituga in February 2011 and to date, 15 reverse circulation drill holes totaling 1,324.5 metres and three diamond drill holes totaling 266.35 metres have been completed at the Little Mobale mine and Kibukila prospects. Exploration drilling is continuing on the Kibukila prospect.
Exploration work in Kamituga during the Q4 2012 involved:
Eight (8) DD holes for 1,118.3 metres were drilled at Kibukila and G22 prospects, and a total of 1,327 samples were generated from the above program.
Trenching continued during the Q4 2012 and a total of 306 samples were collected from 14 trenches representing 301.00 metres of excavated in Kibukila, Filon20 and Kobokobo prospects.
Gridding and soil sampling work had the objective of covering the south-western part of the concession as an extension of the current Kamituga soil geochemistry coverage. The area was prioritized due to an open ended soil anomaly through the southwest of the existing grid. In total, 46.08 line km of grid were opened and 1,156 soil samples and 4 rock chip samples were collected in the Kobokobo prospects using a 160m x 40 m grid pattern.
The 2013 exploration program will focus on delineation drilling of the Kibukira prospect and other targets within the Kamituga Central area. An extensive regional exploration program will also be initiated outside the Kamituga Central area to outline further drill targets.
Full details of the results of the Kamituga exploration activities during 2012 are contained in the Press Release of the Company dated November 15, 2012 and entitled "Banro Provides Exploration Update for Projects in the DRC, Including Significant Drill Intersections at Namoya, Lugushwa and Kamituga". A copy of this press release can be obtained from SEDAR at and EDGAR at .
(v) Regional Exploration Projects
The Company's wholly-owned DRC subsidiary, Banro Congo Mining SARL, holds 14 exploration permits covering an aggregate of 2,638 square kilometres of ground located between and contiguous to the Company's Twangiza, Kamituga and Lugushwa properties and northwest of Namoya.
Using Banro's magnetic and radiometric data that was obtained in 2007, SRK (UK) Consulting Ltd. carried out an integrated qualitative interpretation and target generation work in 2009 on all the permit areas. The report by SRK was qualitative and was based on the magnetic and radiometric data signatures on a large scale only. No quantitative interpretation was done. In 2012, Banro mandated Spectral Geophysics to carry out quantitative reinterpretation of the airborne data to generate additional targets. By applying various filters and transformations to the data one could detect very subtle structures associated with the mineralization. The quantitative re-interpretation work was not completed in Q4 2012. Results of the re-interpretation work will be available in Q2 2013.
Qualified Persons
Daniel K. Bansah, the Company's Vice President, Exploration and Christian Bawah, the Deputy General Manager of the Twangiza Gold Mine, each of whom is a "qualified person" as such term is defined in National Instrument 43-101, have reviewed and approved the technical information in this press release.
Conference Call
Banro will host an investor conference call on Wednesday March 27, 2013 at 11:00am EST.
The conference call will replay will be available from 2:00pm EST on Wednesday March 27, 2013 until 11:59pm EST on Wednesday April 10, 2013.
Banro Corporation is a Canadian gold mining company focused on production from the Twangiza oxide mine and development of three additional major, wholly-owned gold projects, each with mining licenses, along the 210 kilometre long Twangiza-Namoya gold belt in the South Kivu and Maniema provinces of the Democratic Republic of the Congo. Led by a proven management team with extensive gold and African experience, Banro's plans include the construction of its second gold mine at Namoya, at the south end of this gold belt, as well as the development of two other projects, Lugushwa and Kamituga, in the central portion of the belt. The initial focus of the Company is on oxides, which have a low capital intensity to develop but also attract a lower technical and financial risk to the Company and as such maximize the return on capital and limits the dilution to shareholders as the Company develops this prospective gold belt. All business activities are followed in a socially and environmentally responsible manner.
