AFFIRMATIVE ACTION INITIATIVES
To date some 1,105 Ha at the south eastern portion of this lease had been the subject of exploration activities involving outcrop mapping, borehole drilling, quality sampling. Data collected was validated, encoded for computer-aided design and processing, and correlated to come up with a seam geometry and quality model. The volume and quality of the data are found to be sufficient to allow a resources estimation compliant with the requirements of the JORC Code and the Australian Guidelines for Reporting and estimating Inventory Coal, Coal Resources and Coal Reserves.
PT. DAHLIA BIRU has completed land acquisition for stockpile and jetty measuring 40 Ha and 98 Ha for hauling road.
