Heap Leach Pad Inventory Loss

3 verified sources

Definition

Heap leach pads trap valuable metals due to fines accumulation and short-cycled areas, requiring enhanced recovery techniques like gravity wells or injection to access remaining inventory.

Key Findings

  • Financial Impact: 25% lower recovery vs. milling (e.g., AUD 20-50/tonne lost value at 1-2 g/t gold equivalent)
  • Frequency: Ongoing during pad lifecycle, especially end-of-life
  • Root Cause: Inaccurate inventory valuation from poor metallurgical accounting and hydrology modeling

Why This Matters

The Pitch: Metal Ore Mining players in Australia 🇦🇺 lose 25%+ of potential metal recovery on heap leach pads. Automation of geophysical monitoring and targeted solution wells eliminates this inventory loss.

Related Business Risks

Overstated Heap Leach Inventory

AUD 1/tonne pad replacement + G&A misallocation (e.g., 10-20% capex overrun from poor planning)

Gemeindevereinbarung Compliance-Verstöße und behördliche Sanktionen

Estimated AUD 150,000-400,000 per non-compliance incident (work plan rejection + remediation + lost operational time); typical remediation cycle = 90-180 days of operational delay

Manuelle CDA-Dokumentation und Stakeholder-Verwaltung verursacht Projektverschiebungen

40-80 hours per CDA preparation (at AUD 85/hour = AUD 3,400-6,800 per incident); typical project delay cost = AUD 50,000-150,000 per month of delay

Unvollständige Stakeholder-Daten führen zu suboptimalen CDA-Vereinbarungen und Community-Konflikten

AUD 200,000-500,000 per CDA renegotiation cycle; estimated litigation/dispute resolution cost: AUD 500,000-2,000,000 if community conflict escalates

Capacity Loss from Assay Bottlenecks

20-30% lab capacity idle; AUD 100,000+ annual lost throughput per facility

Revenue Leakage from Assay Disputes

1-3% revenue loss per shipment (industry standard for assay disputes); AUD 50,000+ per major error
