*This is an abstract only. No full paper is available for this abstract.* Mining is an inherently risky business; from the technical, environmental, social and economic uncertainties associated with advancing an exploration prospect to a viable project, to the operating, market and safety risks and uncertainties attached to a developed mine. Since one cannot totally escape the risk and uncertainty related to resource projects, there should be an industry-wide improvement in the presentation of the upside and downside risks in the context of the project's development path and maturity. More transparent, consistent and balanced views of technical confidence will better inform both internal and external stakeholders about the expected risk in the project._x000D_
The JORC Code sets out the minimum standards, recommendations and guidelines for Public Reporting in Australasia of Exploration Results, Mineral Resources and Ore Reserves. However, the JORC Code principles of Transparency and Materiality are subject to the interpretation of the Competent Person(s), which may introduce a degree of subjectivity in reporting, particularly the level of disclosure regarding supporting information. It is fundamental that Resources, Reserves and study outcomes are reported so as to unambiguously present the level of inherent technical uncertainty (or confidence) in a project, while conveying a balanced view of the opportunities a project presents. Reporting needs to consider various stakeholders, who may rely on this information, and present the data in the context of the changing risk profile associated with project development paths and project maturity._x000D_
This paper discusses the interdependence of Resource-to-Reserve conversion, the consideration of Modifying Factors through various technical-economic studies and the level of confidence conveyed to stakeholders relying on these technical reports and other company public announcements._x000D_
