CAPE TOWN, SOUTH AFRICA--(Marketwire - Feb. 6, 2013) - Robert Friedland, Executive Chairman of Ivanplats (IVP.TO), announced today that an intensive drilling program during 2011 and 2012 at the company's Flatreef Discovery in the Northern Limb of the Bushveld Complex in South Africa has dramatically expanded and upgraded the Flatreef precious- and base-metal mineral resources.

Speaking in a keynote address at the Investing in African Mining Indaba Conference, Mr. Friedland said that a new mineral resource model based on drilling results audited by AMEC E&C Services of Reno, Nevada, has upgraded more than 220 million tonnes of the Flatreef Discovery's previously declared Inferred Mineral Resources into the higher-confidence classification of Indicated Mineral Resources.

"Flatreef is distinguished from other Bushveld projects by its tremendous size, the remarkable thickness of the polymetallic mineralized reef and its potential for significant by-product credits of nickel and copper," Mr. Friedland said.

"The successful upgrading and expansion of the selective high-grade underground resources advance the definition of the initial mine plan in which we intend to incorporate safe, efficient, large-scale, mechanized mining methods.

"Given that the cumulative true thickness of the two mineralized zones in the currently defined Indicated Resources is 24 metres at a two-gram-per-tonne 4PE cut-off, we firmly believe that the Flatreef Discovery will enhance the future of underground platinum mining in South Africa."

The Indicated Mineral Resource covers an area of 2.8 square kilometres, which at a 2.0 g/t 4PE cutoff corresponds to an average of more than 10 million ounces of precious metals per square kilometre. At a 1 g/t 4PE cutoff, the Indicated Mineral Resource contains on average more than 14 million ounces per square kilometre.

Major expansion and upgrade of resources

Flatreef's Indicated Mineral Resources now total 223 million tonnes grading 4.1 grams per tonne (g/t) 4PE (platinum, palladium, gold and rhodium), 0.34% nickel and 0.16% copper, at a 2.0 g/t 4PE cut-off grade and at a cumulative, average true thickness of 24.3 metres. The Indicated resources contain an estimated 29.2 million ounces of platinum, palladium, gold and rhodium, 1.7 billion pounds of nickel and 800 million pounds of copper.

In addition, the latest estimate includes Inferred Mineral Resources of 410 million tonnes grading 3.3 g/t 4PE, 0.32% nickel and 0.18% copper, at an average true thickness of 18.0 metres. The Inferred resources contain an estimated, additional 44.0 million ounces of platinum, palladium, gold and rhodium, 2.9 billion pounds of nickel and 1.6 billion pounds of copper.

At a higher cut-off grade of 3.0 g/t 4PE, Flatreef's newly reported Indicated Mineral Resources total 138 million tonnes grading 5.0 g/t 4PE, 0.38% nickel and 0.17% copper, at an average vertical thickness of 17.1 metres. At the same cut-off grade, Inferred Mineral Resources now total an additional 181 million tonnes grading 4.4 g/t 4PE, 0.38% nickel and 0.17% copper, at an average true thickness of 12.9 metres.

The new resource estimate substantially increases and upgrades the previous March 2011 Flatreef estimate reported for Ivanplats' Initial Public Offering in October last year, which was based only on Inferred Mineral Resources that totalled 320 million tonnes grading 3.65 g/t 3PE and containing 37.6 million ounces of PGEs, at a 2.0 g/t 3PE cut-off grade.

The new resource estimate incorporates the results from approximately 345,000 metres of drilling completed by a fleet of 30 rigs from March 2011 to August 2012. It was prepared in accordance with 2010 CIM Definition Standards and Best-practice Guidelines and National Instrument 43-101 standards. The underlying geological interpretation, drill hole and assay databases, drill hole co-ordinates and QA/QC were audited by AMEC under the direction of Technical Director Dr. Harry Parker.

Mineralization remains open for expansion along the southern and western boundaries of the Flatreef deposit.

Flatreef Discovery now recognized as a giant Merensky Reef analogue

PGE-nickel-copper mineralization in the Northern Limb primarily is hosted within the Platreef, a mineralized sequence of rocks that extends northward from the town of Mokopane for more than 30 kilometres along strike. Ivanplats' Platreef Project comprises two contiguous licences, Turfspruit and Macalacaskop, in the southern section of the Platreef, adjoining Anglo Platinum's Mogalakwena operations. Within the Ivanplats Project area, the Platreef has a strike length of up to eight kilometres.

The mineralization supporting the Flatreef Mineral Resource, with a strike length of six kilometres, predominantly lies within a flat to gently dipping portion of the Platreef at relatively shallow depths of approximately 700 to 1,100 metres below surface. The currently defined Mineral Resource encompasses only the highest-grade uppermost or "top-loaded" part of the Platreef.

Detailed infill drilling on Turfspruit and groundbreaking work by the company's geologists have resulted in the recognition that the upper Platreef pyroxenite package can be subdivided into a series of cyclic units with strong similarities to the cyclical stratigraphy of the Upper Critical Zone within the Western and Eastern limbs of the Bushveld Igneous Complex. The key mineralized unit, named the Turfspruit Cyclic Unit (TCU), is considered analogous and correlative to the Merensky Cyclic Unit. Within the TCU, two zones of mineralization have been identified: T1m (hosted in feldspathic pyroxenite) and T2 (hosted in pegmatoidal orthopyroxenite and harzburgite). These two zones are considered analogous to the M1 and M2 of the Merensky Reef in the Eastern Bushveld Complex.

The Flatreef also contains markedly higher copper and nickel grades than the normal Merensky and UG2 reefs within the Eastern and Western limbs.

The recognition of cyclic stratigraphy, its control on PGE-nickel-copper mineralization and the subsequent ability to correlate high-grade zones between boreholes have allowed Ivanplats to develop a detailed and robust geological model. This model in turn supports the estimation of Mineral Resources amenable to selective mining methods within the T1m and T2 zones.

"The outstanding work by the Platreef team has greatly advanced our understanding of the Northern Limb, and indeed the Bushveld Complex," said David Broughton, Ivanplats' Executive Vice President of Exploration.

"At a cumulative thickness of 24 metres, the T1m and T2 mineralized zones represent a dramatically thickened equivalent of the approximately one-metre-thick Merensky Reef, which has been the traditional mainstay of PGE mining in the Eastern and Western limbs."

Exploration targets provide upside in adjoining areas

Beyond the current Mineral Resources, the Flatreef mineralization is open to expansion to the south and west. The following Exploration Targets have been identified:

  • Target 1 is based on results from three step-out holes released November 12, 2012, and is estimated to contain up to an additional 31 to 62 million tonnes grading 3.36 to 5.03 g/t 4PE, 0.26% to 0.38% nickel and 0.13% to 0.19% copper over an area of 2.5 square kilometres.
  • Target 2 surrounds the declared Mineral Resources and contains an estimated additional 50 to 220 million tonnes grading 2.9 to 4.1 g/t 4PE, 0.24% to 0.32% nickel and 0.12% to 0.16% copper over an area of 7.6 square kilometres. The tonnages and grades are based on intersections of mineralization in adjacent drill holes located within Inferred Mineral Resources.

The deposit is open for expansion beyond Targets 1 and 2 over an area of approximately 37.5 square kilometres.

These Exploration Targets are conceptual in nature and there has not been sufficient exploration to define them as mineral resources. It is uncertain whether further exploration will result in these targets being delineated as mineral resources.

Technical operations on site are focused on re-logging of shallow drill holes to extend the new geological model of mineralization over the entire Platreef property. Ivanplats' exploration drilling activities at the Platreef site are on hold following notice from the Department of Mineral Resources (DMR) due to community concerns over compensation issues. Discussions are ongoing with the DMR and all key stakeholders to ensure that exploration drilling recommences in the near future.

Exploration shaft and Mining Licence applications planned

Sinking of an exploration shaft is being planned to provide underground access to the Flatreef Deposit to obtain a bulk sample. The Platreef Bulk Sample Application was lodged with the DMR in Polokwane on September 21, 2012, and is awaiting approval.

Ivanplats expects to file a Mining Right Application (MRA) in the second quarter of 2013. As part of the filing, the company is working with its advisers and regulatory authorities to ensure that it meets South African ownership requirements prescribed by the Mining Charter.

Ivanplats is committed to the highest standards of community engagement and participation and intends to fashion the Platreef ownership structure in line with a broad-based, black economic empowerment (BBBEE) model, with the major beneficiaries being local communities, employees and a trust for women and children in the Limpopo province.

Although the Platreef Project still is in the pre-development stage, Ivanplats already has established a presence in communities in the vicinity of its Platreef Project through its community liaison offices. As pledged, in part, in Ivanplats Statement of Values and Responsibilities on the subject of Sustaining Communities, "We are committed to supporting and strengthening existing communities where we live and work. We encourage supportive, cooperative partnerships to enhance social and economic resources. We respect the diversity of multicultural states and local communities. We involve the public and community leaders in the planning, implementation and operation of our projects."

Platreef, as a new development project, will bring many additional high-value jobs, training and other opportunities for those who live in local communities and the region. Work is progressing on a social and labour plan to address skills training and sustainable local economic development projects. Through an ongoing skills and business survey, more than 9,000 people have been interviewed to establish a database of the available skills and skills that will be required in the area. Specific initiatives, including job creation measures, will be announced following consultations with local communities, municipalities and various government departments.
