Marula is 73% owned by Implats and is one
of the first operations to have been
developed on the relatively under-exploited
eastern limb of the Bushveld Complex in
South Africa. Marula is located in the
Limpopo province, some 50 kilometres north
Reserves: 1.2 million attributable ounces
Resources (including reserves) 8.1 million attributable ounces of platinum
Production: 73 600 ounces of platinum
Employees and contractors: 4 379
Marula holds two contiguous mining rights and a prospecting right covering 5 494 hectares across the farms Winaarshoek and Clapham, and portions of the farms Driekop, Forest Hill and Hackney. Marula also has a royalty agreement with Modikwa which allows limited mining on an area adjacent to the Driekop shaft.
Both the Merensky and the underlying UG2 reefs are present and sub-outcrop in the Marula mining right area. The reefs dip generally in a west-southwest direction at 12 to 14 degrees with a vertical separation of some 400 metres between them. While one prominent dyke and a dunite pipe are present,
there is minimal faulting on the property.
MINERAL RESOURCES AND MINERAL RESERVES
Marula Mineral Resources and Mineral Reserve Statement 2015 View online
Current mining activities target the UG2 reef only which is accessed via two decline shaft systems. Driekop Shaft uses a hybrid mining method, while at Clapham Shaft, both hybrid and conventional mining methods are currently being used. In the hybrid sections, all main development is done on reef, and stoping is carried out through conventional single-sided breast mining from a centre gully. The stoping width averages 1.4 metres.
For the conventional operation, the footwall drives are developed on strike approximately 25 metres below the reef horizon with crosscut breakaways about 220 metres apart. Development is undertaken with drill rigs and dump trucks. Stope face drilling is done with hand held pneumatic rock drills with air legs.
The optimisation of Marula’s existing infrastructure over the past few years as well as improved available mining face provides a solid foundation to reach output of 90 000 ounces of platinum per annum in the next few years.
Marula has a concentrator plant where initial processing is done. Concentrator recoveries were 86.4% in FY2015.
Concentrate is transported by road to Impala Platinum’s Mineral Processes in Rustenburg in terms of a life-of-mine offtake agreement with Impala Refining Services (IRS).
Marula focuses on addressing those social, economic and environmental issues that are seen as having a material impact on the long-term success of the business, the sustainability of the economy, the environment and the communities in which we operate or that are important to key stakeholders. The pursuit of sustainable development and zero harm are seen as competitive imperatives.
Marula is determined to maximise the benefits of the mine for its local communities and the social investment strategy focuses on addressing the urgent needs identified in these areas. Preference is given to local contractors and suppliers of goods and services. Makgoma Chrome is a joint venture that assists local communities with the extraction and marketing of chrome from tailings.
Black economic empowerment forms a key component of the Marula operation and our partners together own 27% of the company.
Each of the following parties hold a 9% stake in the business:
The Marula Community Trust ensuring sustainable benefit flows
to the local community over the life of the mine and beyond;
Tubatse Platinum, a broad based HDSA empowerment
consortium from local business; and
Mmakau Mining, an established mining entity.
Implats, as the largest stakeholder, brings technical, managerial, financial and operational expertise to the mine.
Platinum was first discovered in the area by renowned explorer Hans Merensky on the nearby farm Maandagshoek (now Modikwa Platinum) in the 1920’s. In June 1998 Implats entered into an arrangement to acquire the Winnaarshoek property from Platexco, a Canadian based company. The mineral rights to portions of the adjacent farms of Clapham and Forest Hill and a sub-lease to Driekop were subsequently acquired from Anglo Platinum in exchange for Hendriksplaats (part of Modikwa Platinum) so consolidating the Marula mine area. The exploration programme was then expanded and some 750 surface boreholes were drilled. The establishment and development of the mine, requiring considerable investment from Implats in both infrastructure and environmental protection measures, commenced in October 2002.
