DSO Resources and Reserves

View the latest Mineral Resource and Ore Reserve statement in the ASX announcement dated 22 September 2016 here.

2016 Mineral Resources


Mineral Resources are reported inclusive of Ore Reserves
a)       Iron Ore Mineral Resource tonnes are reported on a dry weight basis, tonnes are rounded according to JORC category with grades carried through unaffected by rounding.
b)       Likely mining method: O/P=Open Pit.
c)       Abydos Mineral Resources have decreased due to production at Trigg, Mettams, Cove, Contacios, Leighton and Scarborough, partially offset by a resource model update for Contacios.
d)       Wodgina Mineral Resources have reduced due to production at Avro, Constellation, Dragon, and Hercules.
e)       Mt Webber Mineral Resources have decreased due to production at Ibanez.
f)        Corunna Downs Mineral Resources have increased due to resource model updates for Split Rock, Shark Gully and Runway, reported December 2015.
g)       Other Mineral Resources remain unchanged from 30 June 2015.

2016 Ore Reserves


a)       All Ore Reserves are Iron Ore, reported on an in-situ dry weight basis, to be mined by open pit method or located in stockpiles.
b)       Standard Fines product targets a grade above or at 56.4% Fe. Value Fines are a lower grade product.
c)       The presented tonnages and grades are rounded. Total tonnages and grade are summed on the raw data then rounded.
d)       Ore Reserves at Abydos, Wodgina and Mt Webber decreased following production depletion.

Mineral Resources and Ore Reserves Corporate Governance

Atlas has an established Ore Reserve Steering Committee (ORSC) that oversees the Mineral Resources and Ore Reserves processes and reporting. The committee includes management from geology, operations and mine planning. It meets regularly and is responsible for reconciliation, estimation and reporting of Mineral Resources and Ore Reserves. Ore Reserves undergo rigorous governance and signoff processes extending to all disciplines responsible to satisfy JORC compliance with this process audited by external consultants.

Atlas continues to develop its internal systems and controls in order to maintain JORC (2012) compliance in all external reporting, including the preparation of all reported data by Competent Persons as members of the Australasian Institute of Mining and Metallurgy.
