PURPOSE

A-Reporting codes

B-Competency requirements

C-Resources and Reserves

Reporting CodesJoint Ore Reserves Committee Code (JORC Code) - Australia

National Instrument 43-101 (NI 43-101) - Canada

South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC) – South Africa

These codes are broadly related

Committee Code (JORC Code), and the South African Code for the Reporting of Mineral Resources and Mineral Reserves (SAMREC are

the general standards. .

we will focus on the SAMREC code
