Resgen releases coal resources statement

Published by
World Coal,

Resgen has release a statement of coal resources and coal reserves.

Coal resources

The measured and indicated tonnes of 664.2 million t have increased to 994.81 million t. This is attributable to an increase in the Measured Resource Area as a result of additional drilling.

Coal reserves

The Marketable Coal Reserves have reduced from 430.6 million t to 267.09 million t and are now based on:

  • Ann export quality product with an average of 14% ash and an average 25.73 MJ/kg calorific value determined on an Air Dried (AD) basis.
  • A domestic power station product with an average 19.5 MJ/kg calorific value and an average 31.43 % ash determined on an AD basis.
  • The export quality product has an average yield of 23.68% and the domestic power station product has an average yield of 19.61 %. This equates to an overall average yield of 43.3%.

The run of mine (ROM) of 616.85 million t equates to a life of mine in excess of 40 years at an annual production rate of 15.12 million t and sales for a similar period at a rate of 6.55 million tpy (Production Target). The material assumptions on which this Production Target is based are:

  • Open pit truck and shovel terrace operation.
  • Minimum coal seam/mining height thickness of 0.5 m.
  • Dual product mine applying a minimum total yield cut off of 24%.
  • Appropriate pit slope angles (overall 450).
  • Appropriate mining recovery factors, dilution and contamination.
  • Beneficiation of the coal for a dual product in a high density beneficiation plant and applying appropriate plant factors.
  • The Inferred Coal Resources and Coal Reserves for Ledjadja #1 and Ledjadja #2 and the Coal Resources for Waterberg #1 will be subject to review.
