Chinese delegation to study South Africa’s mineral codes

Tue, 10/02/2018 - 15:22
South Africa’s meticulous set of mineral reporting codes has succeeded in attracting a high-ranking Chinese delegation from the Mineral Resources and Reserves Evaluation Centre of the Ministry of Land and Natural Resources (MRREC) in Beijing. South Africa’s Samcodes Standards Committee (SSC) will host the 18-strong Chinese group from October 15 to November 3, and provide ongoing simultaneous translation at all training events.

New approach to outsourcing

Fri, 04/27/2018 - 00:00
With local and global mining companies operating under continuous pressure to consistently deliver on operational targets, save costs and sustain profitability amid an age of smart business and regulatory uncertainty, local technical services provider Ukwazi is offering a turnkey outsourced technical service solution with a proven track record. This approach is different from the body-shop model, which traditionally does not implement processes, solve problems, give access to a large group of specialists, or provide access to the latest technology. The old model (body-shop approach) merely and temporarily fills a gap, and that could be what the client requires.  What makes the turnkey outsource model different, is that it provides a sustainable service based on tested processes, tested technologies and trained and experienced personnel, says Ukwazi MD Jaco Lotheringen.

Services demand in Africa rising

Fri, 04/13/2018 - 00:00
Over the past two years, local mining engineering consultancy Ukwazi has registered a rise in demand of between 20% and 30% for its service offering across Africa. The demand can mostly be attributed to the openpit operations across South Africa and Africa, but also to openpit operations transitioning to massive mining type underground mine, says Ukwazi MD, Jaco Lotheringen.

Companies find use for abandoned underground coal mines

Fri, 09/22/2017 - 00:00
Forsaken underground coal mines are increasingly being reopened using opencast mining methods, according to independent mining advisory group Ukwazi senior mining engineer Adriaan Strydom, who tells Mining Weekly that this practice is effectively enabled through increased mechanisation. While an underground coal mine was typically dismissed or abandoned once mining activities were complete, this is changing, he notes, adding that mining companies utilise technology as a means to mine the remaining pillars, once labelled to be depleted.

Electricity exports create investment opportunity for S Africa

Fri, 09/22/2017 - 00:00
Power generation stakeholders and key industry players are investigating ways of deriving the most benefit from lower coal qualities, says independent mining advisory company Ukwazi senior mining engineer Adriaan Strydom, who tells Mining Weekly that companies are implementing new technologies to generate electricity from lower-quality orebodies. South Africa has a mature coal-mining history, with coal generation capacity and infrastructure already developed across the country; therefore, mining companies now need to revisit how best to use specific orebodies that have been identified as viable for electricity generation, he points out.

Demand for African resources, but common codes needed

Fri, 07/14/2017 - 00:00
African mining has entered into the new up-cycle for commodities, which is fuelled by the economic growth profile in the eastern hemisphere – which includes China, Mongolia and the Pacific rim region, as well as the global uncertainty over the value of and the sustained availability of ‘cash-money’.

Local miners leverage existing infrastructure to extend operations

Fri, 06/30/2017 - 00:00
As a result of financial constraints, South African gold miners are looking to exploit their existing infrastructure to mine licensed blocks adjacent to existing operations, says mining engineering consultancy Ukwazi Mining. Ukwazi underground engineer Hans Dippenaar notes that, in this way, miners will be able to increase production and revenue without amassing large capital expenditure costs, highlighting that the consultancy is working on such a project for gold miner Harmony Gold.

Independent mining adviser Ukwazi strongly believes in following transparent and compliant mine planning processes by applying specialist teams that are focused on specific mining methods and commodities. “We follow outcome-driven project management principles and supply specialist technical services as required by clients. We are structured to provide on site and off site technical services for small aggregate quarries to some of the largest operations in Africa,” the Centurion, Gauteng, company explains.

Turnaround strategies should be collaborative to unlock value

Fri, 03/11/2016 - 00:00
Gauteng-based mine planning and engineering consultancy group Ukwazi maintains that its opencast coal mining turnaround strategy unlocks value by combining the interrelated processes that exist on a mine. “As commodity prices are at an all time low and markets are under pressure, we believe a cheaper alternative is available in the form of a turnaround strategy. We believe that significant value is unlocked through a collaborative management platform that aligns the objectives of the role-players in control of daily mine production processes. This process is transparent, easy to maintain by mine personnel, and delivers tangible improvements on the face that result in overall production rate and product quality improvements and, therefore, improvements to the end product unit cost,” elaborates Ukwazi.

Coal-to-power project ready for bid submission

Fri, 02/19/2016 - 00:00
Energy company Shumba Energy (SE) has made significant progress on its Mabesekwa Export Independent Power Plant (MEIPP) project, which will be ready for bid submission by mid-2016. The project is located in the Mabesekwa village in Botswana’s Central District. Shumba has started with the bankable feasibility study for the MEIPP, and with a cash balance of $2.85-million, is confident that it will meet its objectives in 2016 as it moves its project towards financial close.

Gauteng-based mine planning and engineering consultancy Ukwazi grew by 29% in 2015, exceeding its average growth rate of between 22% and 23% recorded over the previous five and ten years.    According to Ukwazi director and principal mining engineer Jaco Lotheringen the company’s formal study teams continued to perform well over these periods in their delivery life-of-mine (LoM) plans and feasibility studies for openpit mines, collieries, and caving and mechanised underground and narrow tabular underground mines and projects.

Cost-effective mining can be achieved through technical collaboration

Fri, 11/06/2015 - 00:00
Mines should invest more in effective operational plans to counteract high off-site costs, which in some bulk commodities could be as high as one third of the products total free-on-board product cost, says consultancy, the Ukwazi director and principal mining engineer Jaco Lotheringen. He notes that useful operational plans encompass aligned and collaborated planning meetings, a holistic short-term planning process and excellence in operational execution that is controlled in a transparent and accountable manner. “Operations that invest time and effort in setting up a mine planning and operational execution process that continuously, strategically and authoritatively guide operations, have a higher chance of success in the ever-changing mining climate,” he informs Mining Weekly.

Suitable rail infrastructure can facilitate access to increased coal resources

Fri, 03/13/2015 - 00:00
The establishment and maintenance of efficient and accessible rail and port infrastructure, and the regional linking thereof, could enable State-owned electricity provider Eskom to access a reliable supply of affordable coal, says mining engineering and strategic consultancy services firm Ukwazi Group. Ukwazi Group director and principal engineer Jaco Lotheringen tells Mining Weekly that while South Africa’s neighbouring countries, such as Botswana, Zimbabwe and Mozambique, have large deposits of inexpensive and appropriate quality coal, these resources have historically been underused.

Increased focus on efficient mine planning for SA coal mines

Fri, 09/19/2014 - 00:00
Owing to current coal prices, depleting coal reserves and the increasing need for infrastructure investment, the local coal mining industry is focusing more on efficient mining and processing using existing infrastructure without added capital investment, says mining services group Ukwazi director and principal engineer Jaco Lotheringen. “With the pressure on the coal price, the need for operations to deliver specification products at a low cost has materially increased over the past two years,” he tells Mining Weekly, noting that the uncertainty of coal prices over the medium term further increases the need for most coal companies or coal mines to decrease their unit cost of coal products to remain competitive.

Mechanisation boon for platinum producers – Ukwazi

Mon, 08/25/2014 - 08:27
The unrest that has plagued the local platinum-group metals (PGM) industry over the last two years, culminating in this year’s five-month-long strike, spearheaded by trade union the Association of Mineworkers and Construction Union, has forever changed the operating climate for local PGM miners, says midtier mining consultancy Ukwazi Group director Hugo Tukker. Owing to the increased wage and safety demands made on PGM producers, the industry’s way of doing business has to be reviewed, Tukker tells Mining Weekly.

Mechanisation a boon for PGM producers

Fri, 08/22/2014 - 00:00
The unrest that has plagued the local platinum-group metals (PGM) industry over the last two years, culminating in this year’s five-month-long strike, which was spearheaded by trade union the Association of Mineworkers and Construction Union, has forever changed the operating climate for local PGM miners, says local midtier mining consultancy Ukwazi Group director Hugo Tukker. He tells Mining Weekly, that owing to the increased wage and safety demands enforced on PGM producers, the industry’s way of doing business has to be reviewed. Tukker points out that, like the gold mining industry in South Africa, PGM producers use conventional stoping methods, such as hand-held drilling, which has created thousands of jobs for rock drill operators.
