Description:
Poorly designed sampling protocols generally result in high project risk by artificially increasing grade variability (ie the nugget effect). Sample collection, preparation and assay protocols that suit the ore type, together with QA/QC systems, will reduce this risk. All reporting codes (eg JORC, 2004) require the Competent Person to consider the quality and implication of sampling and assaying programs. High sampling errors beget higher project uncertainty; despite this fact, sampling does not receive the attention it deserves. The case studies presented show that many sampling issues frequently go unrecognised or unaddressed, resulting in poor project decisions during exploration through to feasibility and production. The overall conclusion is that correct sampling is critical to mining project success and that there is often a need for its optimisation.
Description:
This paper reports some preliminary results of a small pilot survey of University of Ballarat students' knowledge of Youth Allowance rates and eligibility criteria and of their attitudes towards the appropriateness of some of the obligations currently placed on young people in receipt of Youth Allowance. Thus it was asked, do students, who may themselves be experiencing poverty, agree with the current range of government imposed obligations on young job seekers?
