PURPOSE OF THE UNIT STANDARD 
The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector.

This unit standard is intended to promote general skills, knowledge and understanding of dimension stone quality and geology in the mining and minerals sector in order to ensure knowledgeable and informed workers.

This unit standard will be useful to people who are responsible for planning and executing dimension stone block extraction and/or dressing of dimension stone blocks.

People credited with this unit standard are able to:
  • Demonstrate knowledge of products, processing technologies and applications of dimension stone.
  • Demonstrate knowledge of dimension stone economics, quality and market requirements.
  • Plan and mark cutting lines for block extraction in quarries.
  • Plan and mark cutting lines for block dressing. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communication and Mathematical Literacy at NQF Level 2.
  • The Basic understanding of dimension stone geology and mineralogy at NQF Level 2.
