Great Thinkers Community

Breakfast Panel Discussion

You're Invited!

Join us on Tuesday March 10th for a Breakfast Panel Event as part of the Great Thinkers Community in mineral resources. In this session, we'll be discussing Transparency and Standardisation in Metal Reconciliation Reporting.

One would argue that how well an operation converts its resources to reserves and ultimately recovers its metal, represents as equally an important a benchmark as either unit cost or total output. Accordingly, until such time as formal reconciliation factors are established and published annually, fundamental questions regarding operational transparency and operational performance across the resource sector are likely to continue.  Are we simply waiting for standards and transparency to be legislated?  Is that right? Or should we as an industry be leading ourselves?

Questions for the panel include: 

  • As professionals, are we comfortable with current reporting structures?
  • What are the implications of reporting reconciliation results with full transparency?
  • Is the status quo sustainable?
  • Are we simply waiting for standards and transparency to be legislated?
  • How do we gain alignment across the industry?
  • How do we as community lead the change?

Moderated by Steve Loach, BHP, we expect a lively discussion along with a hot breakfast, tea and coffee.

Date & Time: 7.00am for a 7.30am start - 9.00am, Tuesday 10th March

Venue: Flux, Perth CBD - 191 St Georges Tce
