Disclosure checks
One rich metre carries the interval
Every drilling, resource and cash-flow announcement is checked against what the ASX itself focuses on when it reviews exploration results. A flag is not an accusation - it's a question worth asking before you invest.
1m @ 54.2g/t Au from 306.1m contributes 82% of the gram-metres of 14.3m @ 4.6g/t Au from 304m in RRLBMRCD394; the rest of the interval is much lower grade.
RRL: Biannual Exploration Update - 2 Nov 202616m @ 0.65% Cu from 44m contributes 93% of the %-metres of 18m @ 0.62% Cu from 42m in E51D022; the rest of the interval is much lower grade. 3 other intervals are carried the same way.
EVN: Discovery and exploration - 15 Sep 20263m @ 18.7g/t Au from 129m contributes 95% of the gram-metres of 8m @ 7.35g/t Au from 126m in YRC3364; the rest of the interval is much lower grade. 3 other intervals are carried the same way.
PRU: Perseus Pursues Growth Opportunities at Yaoure Gold Mine - 17 Jul 2026What DrillScore checks
- Missing tables. A company reporting exploration results for a material project must include a drill-hole table (locations and intercepts) and sections 1 and 2 of JORC Table 1. JORC Table 1 explained
- Metal equivalents. The ASX's position is that equivalents aren't appropriate without metallurgical recovery information - with none given, it assumes 100% recovery. Metal equivalents explained
- Cherry-picking. Reporting only selected results breaches the JORC requirement for balanced reporting of low and high grades. DrillScore compares holes drilled with holes reported. Balanced reporting
- Visual estimates. The ASX discourages estimating mineralisation from visual inspection alone. Visual estimates
- Smearing. When one rich metre supplies most of a long interval's gram-metres. Smearing and the nugget effect
- Money. Fewer than 2 quarters of funding, or a raise that adds 15%+ more shares. Cash runway and raisings
General information only - not financial advice. DrillScore's analyses are produced automatically by an AI model (Claude, by Anthropic) from the company's own ASX announcement and public market data, and scored by a fixed formula (how it works). They can be wrong or incomplete, don't consider your objectives or circumstances, and are not a recommendation to buy, sell or hold anything. Always read the original announcement and consider advice from a licensed adviser.
