1. REPORTING CODE
Harmony has adopted the South African Code for reporting of Mineral Resources and Mineral Reserves (the SAMREC Code), which sets out the internationally recognised procedures and standards for reporting mineral resources and reserves in South Africa. The code was prepared under the auspices of the South African Institute of Mining and Metallurgy (SAIMM). It is modelled on the JORC code of the Australasian Institute of Mining and Metallurgy (AusIMM).
The following tables summarise the inventory of Harmony’s mineral resources and mineral (ore) reserves. The mineral resources are quoted as in situ ounces, above a cut-off and over an estimated stoping width. The mineral reserves are quoted inclusive of diluting material as tonnes and grade delivered to the mill.
MINERAL ORE RESERVES
Mineral resources are declared using a cut-off of 250cmg/t for the underground mines (approximately 2g/t), 0.8g/t for Kalgold and for Lindum, an opencast operation at Randfontein.
*Cautionary note to US Investors. The United States Securities and Exchange Commission (the "SEC") permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this annual report, such as "resources", that the SEC guidelines strictly prohibit us from including in our filings with the SEC.
