Overview

The Trixie Mine is a high-grade gold project located in Utah, USA. Hudson Heartland’s development strategy emphasizes consistent grade control and low-tonnage extraction to maintain predictable yields and maximize return on investment.

The mine leverages a flexible, selective approach that enables short-term production while supporting long-term expansion.

Resource Estimate

Targeted extraction of 25,000 tons/year at a minimum average grade of 19 g/t Au, with potential to exceed 1 oz/ton based on historical production zones.

Mining Method

Cut-and-fill or drift-and-fill technique. This method minimizes surface crushing, enhances ore selectivity, and supports structural integrity through cemented backfill. Each round yields approximately 160 tons per cycle.

Processing

Initial ore is processed via vat leaching in small-scale reinforced concrete tanks. Residual material is transferred to a heap leach pad for secondary recovery. The design ensures efficient gold extraction while reducing processing overhead.

Infrastructure

  • Vat leach tanks (3): Approximately 2,000 sq ft each
  • On-site elution pond and carbon columns
  • Heap leach pad: Cell-based layout for scalable use

Strategic Advantage

  • High-grade vein system with shallow access
  • Flexible mining design enabling six months of non-production for development
  • Low overhead strategy to reduce G&A costs
  • Focused on total cash cost per ounce, not bulk volume metrics

Status

Mining system in place. Development and backfill operations ongoing. Targeting continuous ore
feed and vat leaching cycles in Q3 2025.
