Coal Breaking and Crushing Plant

Coal Breaking and Crushing

Every crushing operation must be thoroughly analyzed. Variations in sizes, level of sizes, specifications for percentage of fines, and friability with the coal must be viewed as. Tests to ascertain crushing characteristics are essential for effective style. Results off their operations could be regarded as only asdesign considerations for a cone crusher splitter for woody biomass guides, not specifications.

When studying a crushing difficulty, the preparation engineer need to determine:

(1) maximum sized lumps in feed, (two) friability, (3) incidence of stone, (4) tons each hour feed, normal and maximum, (five) sizes essential in final product, in volume, (6) allowances for oversize and fines. Apart from these considerations, he should constantly be alert for unusual or completely new conditions that may have an effect on crushing. For example, at a single mine there occurred this kind of high incidence of stone it was identified preferable to inspect and pick the raw feed ahead of the major breaker. At yet another mine, lumps of bituminous coal of unusual hardness occurred and excessive strain was intermittently thrown onto the crusher. With out realizing this specific condition, a crusher as well light in construction might very readily happen to be installed.

Probably the most frequent question on exams are how huge an example should be run. Here knowledge is really a reliable guide. From comparison of test operations with actual operating circumstances, it would appear that trustworthy information could be secured from samples of 100 to 500 lb. The bigger the lumps inside the raw feed, or inside the coarser portions in the crushed product, the bigger must be the sample. 1 coal-preparation firm requests an example equal in pounds to 225 occasions the square in the maximum coal size.

Crushing tests vary to some degree as to technique but the standard operations are basically the exact same. It is required first to evaluate the feed by screening. The quantity of separations is dependent upon the marketable sizes in prospect and also on the problem of the coal. The screenings are weighed for volume. The separated sizes are then run via the crusher and rescreened to decide the item. Within this phase the settings may possibly be varied for the identical size feed, to decide variations in crushed product. Screening tests following crushing need to constantly be enough to establish the feasible level of marketable sizes, as well as the probable fines and oversize.

Bituminous-coal crushing method has progressed towards the extent where it is widespread practice to divide the reduction into stages. Setting up stage circuits offers positive aspects in stabilizing output of wanted sizes with consistent efficiency. If the prime requirement was lump, the mechanical problem was the breaking to marketable lump with as little handling as you possibly can. Usually this was done by a single pass in 1 crusher. Specifications calling to get a large amount of modest screenings result in the mechanical issue considerably more difficult. By reducing the setting of existing coarse crushers, a reduction in size may be produced, but at the tariff of creating an unhealthy amount with the very fine sizes.

Bituminous-coal crushing might be split into three stages as follows: Principal Breaking.-Primary breaking occurs at the entrance towards the plant and includes raw feed flowing into the principal breaker for reduction to some maximum leading size 4, five, six, or 8 in., because of washing or any other preparation purposes. Numerous sizes may possibly be screened and delivered to diverse washing units.

Secondary Crushing.-Secondary crushing units minimize all merchandise received in the washers or direct from your primary breaker to sizes in the array of 1$ or l$-in. to zero. This crushing m2y differ considerably in accordance together with the strategy in the following final stages. Screenings Crushing.-Units for crushing screenings minimize secondary items to final modest commercial sizes, such as 1 to #-in. stoker coal or screenings. Close study of production records shows that this type of staging of the crushing operations yields the biggest tonnages of marketable goods with a lot of constant efficiency. It truly is understood that machine efficiency varies with coals; and special varieties of machines with specific coals may possibly minimize the require for full three-stage reduction. At present, nonetheless, the three-stage layout represents probably the most productive and many economical arrangement for most plant.

Multiple Ounce Gold Hits Continue at Edna May

Catalpa Resources, the fast growing Australian gold producer today reports further high grade assay results from a surface diamond drill program testing high limestone screening vibration technical specification pdfgrade underground targets beneath the open pit at the Edna May Gold Project in Westonia, WA.

Drilling continues to demonstrate strong down-plunge continuity of highgrade gold mineralisation associated with the Edna May reef structures, with numerous high grade intersections being returned including a very significant intercept 0.63m @ 169.1g/t Au from 374.63m in EMD027 and 7.07m @ 25.5g/t Au from 390.06m in EMD028.

Drilling currently underway has also been highly successful in the identification of a fifth and possible sixth high grade zone located in the hanging wall of the Edna May Gneiss. The fifth high grade zone was identified by recently reported intersections of 1.12m @ 45.0g/t Au from 250.33m in EMD021 and 2.26m @ 4.1g/t Au from 230.84m in EMD022 together with 2.30m @ 3.6g/t Au from 230m in EMD020.

The sixth high grade zone was identified by a spectacular multiple ounce intersection of 2.10m @ 64.4 g/t Au from 223.70m in EMD020 supported by a recent narrower high grade intersection of 1.10m @ 38.0g/t Au in EMD022.

The encouraging results from this drilling program are anticipated to improve Mineral Resource confidence to the Indicated category in a significant portion of the area targeted. Drill results from this program also demonstrate both the potential to deliver a significant Resource upgrade and Reserve growth with an expected increase in ounces per vertical metre.

The maiden high grade underground Inferred Mineral Resource currently stands at 660,000 tonnes @ 9.1g/t gold for 195,000 ounces. This Mineral Resource is planned to be updated in February 2011 to include the results of the current drilling with an underground prefeasibility set to commence upon completion, advancing toward the goal of high grade underground production.

Edna May’s Mineral Resource now extends to 550 metres below surface (previously at 300 metres) with high grade mineralisation remaining open at depth. Total Catalpa Mineral Resources are estimated at 2.2 million ounces of gold.

Catalpa seeks to accelerate and expand on its drilling program in line with its vision to enhance the Edna May Gold Project with concurrent mining of high grade underground ore to considerably increase annual gold production.

China, Brazil eye coal rail, ports in Colombia

Colombian President Juan Manuel Santos said on Saturday that China and Brazil were eyeing investmentslab manual books for civil engineering in the Andean nation's coal infrastructure to gain more access to the material. Colombia, the world's No. 5 coal exporter, has seen a five-fold increase in foreign investment, especially in oil and mining, since 2002 due to the country's U.S.-backed offensive that pushed leftist rebels to remote jungle hide-outs.

"(China's Development Bank and China Railways gave me a list of where they want to invest. They want to invest in a 250-kilometer (155-mile) railway uniting the Pacific and the Atlantic. The cost of that would be $2.7 billion, and also in the Carare railway," Santos said. "The Brazilians have told me they want to make not only a railway but also a port in Carare because they're very interested in our metallurgical coal ... the Chinese are also interested in our metallurgical coal," he said in a statement...

Profits rise while new projects take shape - Randgold Resources

Randgold Resources today posted a quarterly profit increase of 52% on the previous quarter and 92% on the corresponding prior year quarter, while its profit for the six months to June was up 88% year on year.

Randgold today also announced that commissioning of the plant at its new Tongon mine in Côte d’Ivoire was under way ahead of schedule. Because of the expected earlier start-up, Tongon’s production guidance for this year had been increased by approximately 10%. The company said it is targeting to bring the start of construction at the giant Kibali project in the Democratic Republic of Congo forward by six months to the middle of 2011 in the light of the rapid progress it had made in the pre-development phase.

While production for the quarter was down 17%, the profit of US$36.4 million was boosted by a higher gold price, a gain of US$6.3 million on the sale of part of the company’s stake in Volta Resources and by the write-back of a US$13 million provision in respect of an investment in Auction Rate Securities following the settlement of this issue.

Production and hence the cost profile for the quarter were impacted by issues at Randgold’s flagship Loulo operation in Mali, which suffered from extensive power black-outs during the period. Loulo is also still settling down its plant expansion project and dealing with the Yalea underground development. Production and cost levels are expected to be back on target by the fourth quarter.

Chief executive Mark Bristow said in spite of the dip at Loulo the group’s production guidance for the year remained within 5% of the original target.

“The increased contribution from Tongon will almost make up for the expected shortfall from Loulo, while Morila is holding steady. We’re therefore forecasting attributable production to be within 5% of the 477 000 ounces we gave as our guidance at the beginning of the year,” he said.

“This is a creditable performance given the very substantial challenges we’re dealing with this year at the start of our multi-mine growth phase.”

Bristow noted that the US$6.3 million realised through the disposal of part of the company’s shareholding in Volta was in effect an exploration profit as Randgold had received the shares in part consideration when it sold its Kiaka discovery in Burkina Faso to Volta. “Kiaka didn’t fit our development criteria but it was another significant deposit generated by our exploration programmes and we have continued to crystallise value from it,” he said.

Randgold today also said the continuing feasibility study on its Gounkoto target in Mali was confirming its potential. The company was now considering whether to develop it as a standalone open pit and underground operation or to combine it with the nearby Loulo in a high grade, low cost and long life megamine.

Properties of Recycled Concrete Aggregates

Properties of Recycled Concrete Aggregates

Recycled concrete aggregates (RCA) have higher water absorption rates than virgin aggregates. Higher absorption rates are indicative of higher volume fractions of old cement mortar sticking with the virgin aggregate particles within the original concrete1-3. ASTM C 33, Specification for Concrete Aggregates, carries a dependence on an abmachine for reduce coal moisture contentrasion loss (by ASTM C 535) of lower than 50% for aggregates used in concrete construction and much less than 40% for crushed stone used in pavements4. In line with the ACI 555 Committee Report4, all RCA with the exception that made from the poorest quality recycled concrete, can be expected to meet these abrasion loss requirements. The abrasion property with the aggregates controls the abrasion resistance with the concrete, a property that's essential for warehouse floors, and concrete pavements. The relative density of RCA is 5%-10% less than that relating to virgin aggregates (VA)5. This is due to bricks in demolished construction waste6 and/or the lower density of the cement mortar that is still honored the aggregates.

Construction and Demolition Debris

Construction and demolition (C&D) debris is excess material produced during new construction, renovation, and demolition of buildings and structures. This debris comprises of materials such as asphalt, brick, concrete, masonry, lumber, shingles, roofing materials, glass, plastics, aluminum, steel, architectural elements, drywall, insulation, wiring, plumbing and electrical fixtures, vinyl and aluminum siding, corrugated cardboard, soil, rocks, tree stumps and other landscaping. Standard construction and demolition operations haul and dispose these materials en masse to separation and transfer facilities in order to permitted landfills. Some C&D facilities may separate materials on site for more processing and recycling. Others simply add materials towards the heaping piles of waste inside the landfill. With the total recorded4 waste stream, 30-40 percent is shipped to municipal landfills, 35-45 percent is shipped to specialty C&D landfills, and 20 to 30 percent of C&D debris is recycled.

Economic Development and C&D Recycling

There are community-level great things about recycling and reuse of C&D debris. Diversion of materials through recycling or salvage supports economic development as well as the improvement of communities. Sometimes known as waste-based development, recycling and reuse industries create jobs and revenue, provide small business development opportunities and job training outlets, minimizing landfill expansion needs.

C&D recycling may be used within a larger industrial development effort to create higher wage jobs with a region. Studies conducted by the Waste to operate Partnership13 and the US Economic Information Study14 indicate manufacturing of secondary materials increases the economic impact of recycling collection and processing fourfold. Wage rates in manufacturing are typically more than those wages in collection or processing. The range and processing phases do provide low skilled and entry-level workforce opportunities in the region.

Petmin declares maiden dividend

JSE- and AIM-listed multi-commodity mining and processing company Petmin Limited today reported results for the year-ended June 2010, declaring a dividend of 6 cents per share. Petmin Chairman, Ian Cockerill, commented that, “These results are very pleasing,flowchart material balance stone crusher particularly given the difficult trading conditions experienced for most of the financial year.

“Our deliberate focus on quality assets, in the right markets, combined with a disciplined approach to cost management, has continued to deliver results for Petmin. With the payment of this dividend we are pleased to be able to reward shareholders today as we continue to nurture and grow the company for the future.”

“The performance of our assets, combined with the company’s ability to generate strong cash flows and a healthy balance sheet, means that Petmin is well-positioned to continue to deliver on its organic and acquisitive growth strategy.

“We announced capital expenditure of R120 million for the construction of the second coal processing plant at Somkhele in KwaZulu-Natal, South Africa in August 2010. This second plant will double current production capacity to approximately 1.1 million sales tonnes a year, and will be commissioned by the end of the first quarter of the 2012 calendar year. Further expenditure of R18 million has now also been approved for exploration at Somkhele, following the renewal of new order prospecting rights over Areas 4 and 5 by the Department of Mineral Resources.

Operating and financial results

Revenue for the year ended 30 June 2010 was R489 million. On a like-for-like basis (that is excluding the sale of Springlake), revenue for the 2009 financial year was R524 million.

Revenues at both the Silica (SamQuarz) and Anthracite (Somkhele) divisions were affected by poor market conditions in the first quarter of FY2010, although market conditions steadily improved throughout the remainder of the financial year.

Profit before tax was R154 million (2009: R171 million). Again, the reduction of R17 million from 2009 was owing to the comparative number including profit before tax of R33 million from the Springlake Colliery disposed of in 2009.

Pleasingly, the group achieved a gross profit margin of 37% (2009: 27%) as a result of improved cost and revenue management and improved prices for anthracite in particular.

Operations remained strongly cash generative, producing R321 million (2009: R225 million), including inflows from changes in working capital of R51 million (2009: outflows of R62 million).

Capital expenditure of R123 million (2009: R291 million) was incurred in the year to 30 June 2010, with R57 million spent on pre-stripping of the open pits at Somkhele (2009: R86 million), R55 million to expand operations (2009: R188 million) and R11 million to maintain operations (2009: R17 million).

The ratio of interest-bearing debt to equity at 30 June 2010 was 7.55% (2009: 9.97%). An amount of R35 million was drawn on the medium-term facility at SamQuarz during FY2010. The Rand Asia debtor financing facility of R38 million was repaid during FY2010.

Based on the current financial position of the company, the directors have declared a maiden dividend and introduced a conservative yet meaningful dividend policy. Given the inherent volatility associated with the commodities market and taking into account Petmin’s relative size, the dividend will initially be 20% of headline earnings per share and the payment of dividends will be considered annually after year-end.

The total dividend proposed is 6 cents per share comprising 4 cents based on headline earnings and a 2 cents special dividend from the cash received on the sale of Springlake in July 2009. The total cost to Petmin will be approximately R34.9 million (before STC).

Ian Cockerill concludes that, “Petmin is well positioned for acquisitive growth with low gearing and substantial cash resources. The objective of this growth strategy is to significantly increase the size of Petmin and provide superior returns to investors. All the opportunities being assessed relate primarily to commodities that feed into infrastructure growth and urbanisation (in essence the steel value chain) and comprise a mix of cash-producing assets and projects with a diverse geographic spread.

“Our strategy of rewarding shareholders through a combination of growth and dividend flow, which is a key differentiator of Petmin within its market segment, ensures a focused approach by management to both current operations and new acquisitions: the company must ensure that all operations and projects deliver sufficient returns to cover expenses, fund the required capital expenditure and growth, and recompense shareholders for their investment.”

high power Electrical Mining Machines

Abstract

This paper introduces a new use of a proven technologies to provide dynamic,voltage regulation in underground mine electrical distribution systems.This technology acts to"stiffen"the electrical energy feeding continuous miners and gegold leaching reactor manufacturersnerally raise and increase the voltage regulation in the continuous mining machines which may possibly be located over extended cable distances from the mine incoming electrical substation.

This is extremely useful for big underground continuous mining operations designed to use high power electrical mining machines fed more than extremely lengthy cable lengths(measured in 10s of km,from mine shaft to mine operating face).This new technologies offers rapidly acting dynamic voltage regulation(voltage help)although beginning continuous borers and extensible conveyor belts.Furthermore,when the mine is affected with less distribution voltage because of lengthy cable lengths,this new technology will raise the overall voltage at the mining machine,which may elevated mining machine production and cause longer motor life.

The technologies is depending on voltage source converters operating as static VAR compensators specially packaged for your harsh underground mine environment.Even though static VAR compensator technologies continues to be effectively used in utility and huge industrial applications for a lot of years(like open pit mining and arc furnaces),it has not(until now)been utilized for underground mining.

The paper will present the issue of poor voltage regulation in underground mines on weak electrical utility networks.It'll then talk about several of the alternatives which have been used to resolve this voltage problem.It'll then introduce the new technology used to resolve the issue and critique the troubles associated with making use of this technologies within the harsh underground atmosphere.Finally,the paper will show preliminary efficiency outcomes from a genuine installation inside a huge underground continuous mining operation in Canada.

Higher Production Capacity

The torque developed by mining machine motors varies with all the square of the applied voltage.If the voltage fed towards the mining machine motor is decreased by 5%,the torque developed in the motor shaft is lowered 10%.If the voltage fed towards the mining machine motor is lowered by 12%,the torque at the motor shaft is lowered 23%.Because orebodies mined by electrical mining machines have a particular comparatively constant power dependence on each and every ton of ore extracted,the decrease in shaft torque has a direct effect on mining machine production.A four rotor continuous mining machine with 4 500HP head motors experiencing a 12%reduction in voltage will simply have 1540HP available in the motor shafts.If the voltage regulation program is installed with a point close for the load, the voltage fed towards the mining machine may be regulated to 100%nominal voltage,thereby rising the shaft torque to style ratings.This enables complete production from your mining machines.

Application of Underground voltage regulation systems

An engineering study should be practiced prior to the application of a voltage regulation method.An engineering study would include a load flow study, harmonic study,and a quantity of method simulations and system response research to help within the correct style and use of a voltage regulation program.These studies are necessary to ensure a solid engineering style in the voltage regulation program but as well to establish the consequences the voltage regulation system may have around the mine electrical method during standard and abnormal circumstances.

Once the electrical capacity too as control method style of the voltage regulation program may be determined,it is then necessary to style the overall method taking into account the mine operating environment,operating practices too as maintenance practices.

A current improvement within the mining sector may be really helpful for mine operators who operate high power electrical mining equipment in their mine production process.This development is the Voltage Regulation Method developed particularly for that durable mine atmosphere to supply high-speed,dynamic voltage regulation for the mine electrical distribution systems.This paper discusses this new technologies and offers some background concerning voltage drops experienced more than long mine feeder cables.

The results of this drilling will be used for an updated resource estimate to be completed in the first quarter of 2011 as part of the feasibility study. Two additional drills are scheduled to arrive at Debarwa within the next ten days and will be used for gathering geotechnical and hydrological study data for the feasibility study before moving to other targets for exploration drilling...

Kentor Gold: Gold mining underway at Murchison, start up on schedule for mid year

Kentor Gold is on track to join the ranks of Australian gold producers, with mining underway at the Murchison Gold Project.

The company is on track to achieve the first gold pour from Murchsbmchina for iron ore benefication plantison in June 2012.

Initial production will come from the Lewis and Reward pits, with rates forecast at 24,000 ounces per year from a combination of open pit and underground mining.

Based on the current US$1543 spot price this would create gross revenue of nearly US$40 million in the first year of operation.

Commissioning of the ore crushing circuit has been completed, and 3,000 tonnes of stockpiled underground ore has been crushed in preparation for commissioning of the grinding circuit, which will commence in June.

Processing of grade control samples can begin this week following successful commissioning of the onsite sample preparation laboratory.

All tanks have been installed, with top of tank steel work and the remaining structural steel being installed.

The major concrete work has been completed, while the elution circuit and gold room have been refurbished and will be lifted into place this week.

Electrical work has commenced and all underground mains cabling has been run in preparation for transformer installation next week. Installation of a tailings line from the plant to the Reward pit is underway.

The Murchison project comprises the Burnakura gold and Gabanintha gold-copper sites, located about 50 kilometres south of Meekatharra in Western Australia.

A Scoping Study is underway for a heap leach operation, which will comprise Phase 2 of the development program, planned for next year.

Kirkland Lake Gold raises C$50m to fund mining operations in Ontario

Kirkland Lake Gold has raised C$50 million via a placement of convertible debentures to fund the expansion of its mining operations in Ontario.

The company told inveiron ore concentrate production processpage2stors that a syndicate of underwriters led by Dundee Securities has agreed to buy 50,000 convertible unsecured debentures at a price of C$1,000 per debenture.

The underwriters have also been granted an option to subscribe to up to an additional 15 percent of the offering, which is exercisable up to two days before the closing date of July 19.

These debentures will mature in June 2017 and will have an interest rate of sic percent.

Back in March, Kirkland Lake took full control of seven gold projects in the Kirkland Lake Gold Camp in Ontario by acquiring joint venture partner Queenston's 50 percent interest in the assets.

Kirkland Lake said it would start exploration drilling immediately from both underground and surface on these properties.

Broker Panmure Gordon welcomed the news, saying the move opened up low cost exploration alternatives in this high grade South Mine Complex zone, while reiterating its ‘buy’ recommendation on the stock.

“The economies of scale on offer in the development of such contiguous (and potentially high grade) properties also provide the rationale for the transaction,” said analyst Alison Turner.

“Subject to exploration results we expect this to be a value enhancing deal over the mid term.”

Small scale gold mining in Ghana

The small-scale gold and diamonds mining business is of wonderful importance to Ghana. Considering that its regularization in 1989 the sector has made and sold over 1.5 million troy ounces of gold and 8.0 million carats of diamonds. In the course of the exahow to convert a vertical shaft engine to run horizontallyct same period the sector also provided direct employment to over 100,000 men and women and enhanced the socioeconomic lifetime of many men and women and communities. Even so, these had been largely achieved in a expense towards the atmosphere in locations exactly where mining is done and there is the require to develop the business in a sustainable manner. This paper looks at the developments in the small-scale gold and diamonds mining industry in Ghana and proposes some methods how the concepts of sustainable improvement may be applied towards the business.

Socioeconomic significance of small-scale mining

The small-scale mining of these valuable minerals has produced considerable socioeconomic impact on several people and communities since it offers each part- and fulltime jobs for that folks as well as in some circumstances it truly is the only supply of revenue accessible for the folks. Inside the rural communities where mining takes place, the game has reduced rural exodus, promoted local financial development and contributed towards poverty reduction.

In addition, the mining operations are useful in simple skill improvement and contribute for the transformation of unskilled labor into semi-skilled and skilled workers. More importantly, because of the lower barriers to entry in terms of capital wants and formal educational requirements, small-scale mining operations supply exceptional opportunities for that evolution of indigenous entrepreneurs. In rural regions exactly where other tasks are low paying or non-existent, small-scale mining looks like a valuable source of employment. The sector also supplies raw supplies for local industries.

AngloGold Ashanti to restructure BEE transactions

AngloGold Ashanti, the National Union of Mineworkers (NUM), Solidarity, UASA – The Union (UASA), Izingwe Holdings and the Bokamoso ESOP board of trustees on Thursday announced agreements between them on the restructuringmachine sous gratuit sans tlchargement of the empowerment transactions concluded respectively between AngloGold and the unions, and between AngloGold and Izingwe in 2006.

Anglo said the new arrangements followed a period of consultation between the parties which began late last year. "The interactions were motivated by the fact that share price performance since the onset of the 2008 global financial crisis led to a situation where the first two tranches of E shares, which operate essentially as share appreciation rights, vested and lapsed at no additional value to Bokamoso ESOP beneficiaries and Izingwe," the company said.

"Ordinarily, this would be accepted as a normal risk of share ownership. However, AngloGold Ashanti takes the view that the empowerment transactions were designed to enable AngloGold Ashanti to further play its part in ameliorating SA’s historical legacy."

AngloGold Ashanti CEO Mark Cutifani said, "We’ve taken a proactive stance, in partnership with Izingwe and our employees, to ensure this economic empowerment initiative has the intended benefit. We believe this has been achieved at a very reasonable cost to shareholders, while delivering clear upside for AngloGold Ashanti, its employees and South Africa as a whole.”

Izingwe Holdings chairman Sipho Pityana added, “Our common commitment to create an inclusive economic dispensation, by redressing the unfair discrimination of the past, resonates powerfully when major players in the economy, of the kind AngloGold Ashanti is, take decisive steps to ensure the success of the black economic empowerment project. The fact that this was done without pressure from government is positive commentary on AGA and its leadership”

AngloGold said it's board had seen it appropriate that, as far as possible the E shares, on vesting, should see the transfer of an element of value. ESOP beneficiaries also benefited from ownership of ordinary shares transferred at no cost. This aspect of the ESOP would therefore be unaffected by the restructuring transaction. The company said in order to remedy the previous situation in a manner that would ensure an element of value accruing to all participants, though at a reasonable incremental cost to AngloGold Ashanti shareholders, the following had been concluded:

• Lapsed loan shares that vested without value will be reinstated

• The strike (base) price will be fixed at R320 per share for the Bokamoso ESOP and R330 for Izingwe

• The notional interest charge will fall away

• As previously, 50% of any dividends declared will be used to reduce the strike price

• As previously, the remaining 50% is paid directly to participants under the empowerment transaction

• The life span of the scheme will be extended by an additional one year, the last vesting being in 2014, instead of 2013. A minimum payout on vesting of the E shares has been set at R40 each and a maximum payout of R70 each per E Share for Izingwe and R90 each for members of the Bokamoso ESOP (ie employees), plus the impact of the 50% of dividend flow.

May Hermanus, who chairs the Bokamoso ESOP board of trustees, speaking also on behalf of union nominees on the board, said: “The absence of value flowing to members on vesting dates in respect of the E shares was worrying to trustees and members of the scheme. We therefore welcome the constructive and creative thinking that has gone into remedying this problem for ESOP members”
