As previously announced on 4 September 2012, the CBP tenement covers an area of approximately 195 hectares, and has been previously drilled. Orpheus’ technical team has conducted desktop analysis on earlier exploration results, identifying a minimum of two coal seams varying in thickness from 4 to 12 metres, near surface.

Orpheus currently has an exploration target of 2.0 - 4.5Mt and the current drilling program is expected to delineate a JORC resource.

The CBP project is located approximately 6km south-west of Orpheus’ ADK project and is close to the river side barge loading facility at SKJM, located less than 2km away.

During the current CBP drilling program, Orpheus is developing its preliminary mine plan so that the project can rapidly move into production, planned to be in Q4 2012. At this stage, it is anticipated that the CBP project will be mined at a rate of 50,000tpm, when in steady-state production.
