  2. Qualified Person G. Chunnett, Pr.Sci.Nat, Anglo Platinum October 2007.
  3. Source: Independent QP G.J. van der Heever, November 2004. The mineral resources are based on a US$20 gross metal value per tonne cut-off. Gross Metal Value per tonne (GMV/t) is sum of Pt, Pd, Au, Cu and Ni grades multiplied by the following metals prices: Pt - US$%650/oz; Pd - US$%250/oz; Au - US$%375/oz; Ni- US$%4/lb; Cu - US$%1/lb.

Cautionary note to U.S. Investors

This website uses the terms "measured resources" and "indicated resources". Atlatsa advises investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission ("SEC") does not recognize them. Investors are cautioned not to assume that any part or all of mineral deposits in these categories, not already classified as reserves, will ever be converted into reserves. In addition, requirements of Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") for identification of "reserves" are not the same as those of the SEC, and reserves reported by us in compliance with NI 43-101 may not qualify as "reserves" under SEC standards. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Investors should refer to our Annual Report on Form 20-F available at http://www.sec.gov/edgar.shtml.

This website uses the term "inferred resources". Atlatsa advises investors that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. "Inferred resources" have a great amount of uncertainty as to their existence, and 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 rules, estimates of inferred mineral resources may not form the basis of economic studies, except in rare cases. Investors are cautioned not to assume that any part or all of an inferred resource exists, or is economically or legally mineable.
