Re-testing from Sampling Bias

1 verified sources

Definition

Sampling bias in manual coal quality processes leads to invalid results, necessitating costly re-sampling and re-analysis, impacting cost of poor quality.

Key Findings

  • Financial Impact: AUD 10,000-50,000 per re-test incident (lab fees, delays); eliminates re-testing need via validated methods[1]
  • Frequency: Per batch of non-compliant samples
  • Root Cause: Effects of sampling bias in manual handling, detected post-report

Why This Matters

The Pitch: Australian coal miners incur AUD 10,000-50,000 per incident in re-testing costs. Automated analysis eliminates need for re-tests on biased samples.

Related Business Risks

Sampling Error Financial Risk

AUD 500,000+ per project in minimised financial risk from better resource definition; 80% of errors from sampling[4][3][5]

Resource Misestimation Losses

2-5% revenue loss from inaccurate reserve estimation (industry standard for quality data errors)[5][3]

Queensland Black Lung Regulatory Non-Compliance & System Failures

LOGIC estimate: Regulatory penalty range AUD $50,000–$500,000+ per operator for safety violations (analogous to Fair Work/WorkSafe prosecution bands); Administrative cost of mandatory system remediation: estimated AUD $2–5 million industry-wide (2016–2025) for new surveillance infrastructure, audits, legal defence; WorkCover fund exposure: each compensated worker represents AUD $16,900+ annually ($325.70/week).

WorkCover Claim Processing Delays & Administrative Friction (Black Lung)

LOGIC estimate: Average claim settlement delay 6–12 months (industry standard for complex occupational disease claims in Australia). Per-worker cost: AUD $16,900–$33,800 annual entitlement (at $325.70/week). WorkCover fund impact across ~29 known cases (2015–2017): AUD $245,000–$980,000+ in delayed payments. Administrative overhead per claim: 40–60 manual hours (medical coordination, verification, legal review) = AUD $2,400–$3,600 per claim in labour cost (assuming AUD $60/hour).

WorkCover Fund Capacity Drain from Black Lung Undiscovery & Late Detection

LOGIC estimate: Early detection (simple CWP) → AUD $16,900/year benefit cost; Late detection (progressive massive fibrosis with comorbidities) → estimated AUD $35,000–$50,000+/year (increased disability rating). Per-case cost differential: AUD $18,000–$33,000 annually. Across 29 known cases with average 15-year benefit duration: AUD $7.9–14.3 million total excess fund exposure (2015–2030 projection). Additional: ~40% of late-stage cases may trigger early termination pension claims (permanent disability) vs. time-limited partial disability, increasing actuarial liability.

Contract Pricing Volatility & Lock-In Risk

AUD 15-25 million/year per major operator; margin compression of 10-15% on long-term contracts; example: steelmaking coal unit costs +47% (2018-2025) vs. price at $215/mt (Dec 2025, down from $670/mt March 2022 peak)
