IMPORTANT NOTICE This report includes results for Mineral Resources. The report communicates the updated Mineral Resource estimate for the Waterberg Project. The reader is warned that Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. This technical report contains forward-looking information within the meaning of Canadian securities laws and forward-looking statements within the meaning of U.S. securities laws ("forward-looking statements"). Forward-looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, plans, postulate and similar expressions, or are those, which, by their nature, refer to future events. All statements that are not statements of historical fact are forward-looking statements. The Company cautions investors that any forward-looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those in forward looking statements as a result of various factors, including, but not limited to, variations in market conditions; the nature, quality and quantity of any mineral deposits that may be located; metal prices; other prices and costs; currency exchange rates; the Company's ability to obtain any necessary permits, consents or authorizations required for its activities; the Company's ability to access further funding and produce minerals from its properties successfully or profitably, to continue its projected growth, or to be fully able to implement its business strategies and other risk factors described in the Company's Form 40-F annual report, annual information form and other filings with the SEC and Canadian securities regulators, which may be viewed at www.sec.gov and www.sedar.com, respectively. Cautionary Note to U.S. Investors Estimates of mineralisation and other technical information included or referenced in this technical report have been prepared in accordance with NI 43-101. The terms "mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility CJM Consulting, South Africa, (Pty) Ltd. studies, except in rare cases. Additionally, disclosure of "contained ounces" in a resource is permitted disclosure under Canadian securities laws; however, the SEC normally only permits issuers to report mineralisation that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measurements. Accordingly, information contained or referenced in this technical report containing descriptions of the Company's mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United States federal securities laws and the rules and regulations thereunder.

Preface Almost a year ago Aberra Mogessie planned to organize a field excursion for the students of the Institute of Earth Sciences, University of Graz. The choices were Argentina, Ethiopia (where we had organized past excursions) and South Africa. Having discussed the matter with Christoph Hauzenberger concerning geology, logistics etc. we decided to organize a field excursion to the geologically interesting mining areas of South Africa. We contacted Christoph Gauert from the University of Free State, South Africa to help us with the local organization especially to get permission from the different mining companies to visit their mining sites. We had a chance to discuss with him personally during his visit to our institute at the University of Graz in May 2014 and make the first plan.

WITS 2050, Johannesburg, South Africa) ECONOMIC GEOLOGY RESEARCH INSTITUTE INFORMATION CIRCULAR No. 369 December, 2002 CHROMITITES OF THE BUSHVELD COMPLEX – PROCESSES OF FORMATION AND PGE ENRICHMENT ABSTRACT The mafic layered suite of the 2.05 Ga old Bushveld Complex hosts a number of substantial PGE-bearing chromitite layers, including the UG2, within the Critical Zone, together with thin chromitite stringers of the platinum-bearing Merensky Reef. Until 1982, only the Merensky Reef was mined for platinum although it has long been known that chromitites also host platinum group minerals. Three groups of chromitites occur: a Lower Group of up to seven major layers hosted in feldspathic pyroxenite; a Middle Group with four layers hosted by feldspathic pyroxenite or norite; and an Upper Group usually of two chromitite packages, hosted in pyroxenite, norite or anorthosite. There is a systematic chemical variation from bottom to top chromitite layers, in terms of Cr : Fe ratios and the abundance and proportion of PGE’s. Although all the chromitites are enriched in PGE’s relative to the host rocks, the Upper Group 2 layer (UG2) shows the highest concentration.

  • Noritic Anorthosite Bodies in the Sierra Nevada Batholith
    MINERALOGICAL SOCIETY OF AMERICA, SPECIAL PAPER 1, 1963 INTERNATIONALMINERALOGICAL ASSOCIATION,PAPERS, THIRD GENERAL MEETING NORITIC ANORTHOSITE BODIES IN THE SIERRA NEVADA BATHOLITH ALDEN A. LOOMISl Department of Geology, Stanford University, Stanford, California ABSTRACT A group of small noritic plutons were intruded prior to the immediately surrounding granitic rocks in a part of the composite Sierra Nevada batholith near Lake Tahoe. Iron was more strongly concentrated in the late fluids of individual bodies than during the intrusive sequence as a whole. Pyroxenes are more ferrous in rocks late in the sequence, although most of the iron is in late magnetite which replaces pyroxenes. Both Willow Lake type and normal cumulative layering are present. Cumulative layering is rare; Willi ow Lake layering is common and was formed early in individual bodies. Willow Lake layers require a compositional uniqueness providing high ionic mobility to explain observed relations. The Sierran norites differ from those in large stratiform plutons in that (1) the average bulk composition is neritic anorthosite in which typical rocks contain over 20% AbO" and (2) differentiation of both orthopyroxene and plagioclase produced a smooth progressive sequence of mineral compositions. A plot of modal An vs. En for all the rocks in the sequence from early Willow Lake-type layers to late no rite dikes defines a smooth non-linear trend from Anss-En76 to An,,-En54. TLe ratio An/ Ab decreased faster than En/Of until the assemblage Anso-En65 was reached and En/Of began to decrease more rapidly. Similar plots for large stratiform bodies show too much scatter to define single curves.

  • An Hypothesis for the Origin of Kimberlite 51
    Mineral. Soc. Amer. Spec. Pap. 3,51-62 (1970). AN HYPOTHESIS FOR THE ORIGIN OF KIMBERLITE IAN D. MACGREGOR Department of Geology, University of California, Davis, California 95616 ABSTRACT Kimberlites are characteristically associated with a suite of mafic and ultramafic xenoliths whose mineralogy indicates an origin within the upper mantle. The phase chemistry of the xenoliths may be reconciled with known experimental data at high pressures, as suites of crystal cumulates, or residual phases, that have formed during the high-pressure fractional crystallization of a mafic magma. The geological association of kimberlites with specificsuites of xenoliths, and the com- parison with experimental data, give support to this cognate hypothesis previously proposed by a number of other authors. Models of the Earth's thermal history indicate that the upper mantle heated up for the first few billions of years after which time it has slowly cooled to its present state. It is postulated that the kimberlites are formed by the closed system fractional crystallization of mafic magmas which have formed by fractional fusion during the early heating of the upper mantle. During the cooling cycle in the last few billions of years, the mafic liquids have cooled through fractional crystal- lization to the ambient mantle temperatures, and changed composition towards a kimberlite. Sequential primary phase assemblages are represented by harzburgite, garnet harzburgite, garnet lherzolite, hypersthene eclogite, eclogite, kyanite eclogite to an olivine-diopside-perovskite rock. Parallel changes in the liquid composition are through picrite, tholeiite, alkali basalt, a diopside-ilmenite composition to kimberlite. INTRODUCTION logical and geophysical characteristics common to the gen- Although kimberlites occupy only a very small propor- eral description included in the following section.
