Enhanced Metal Recovery
Improving Resource Extraction
Enhanced recovery is a subsurface hydrometallurgical leaching approach that promotes direct contact between solutions and under-leached zones deep within the pile. It is designed to stimulate production, reduce passive inventory, and increase the movement of fluid into areas that have remaining metal. We provide the tools, experience, and expertise required to design and support these programs.
Enhanced Metal Recovery
Pathways for Better Leaching
Our enhanced metal recovery technology increases solution access to deeper or poorly contacted zones by creating pathways that improve distribution and flow. Adjustments to design, spacing, pressure, and duration help solutions contact under-leached material. By monitoring performance, we track solution movement, coverage, and effectiveness–allowing refinement of the approach to optimize drawdown and overall recovery.
Enhanced Metal Recovery
Reducing Excess Inventory
Enhanced recovery addresses zones that remain dry, uncontacted, or poorly leached. These areas retain significant metal inventory that normal operations cannot access. Our technology improves penetration into compacted, channelized, or isolated regions of the leach pad, helping you overcome uneven flow, limited drainage, and passive metal retention that slow or restrict complete extraction.
Enhanced Metal Recovery
Value Focused Understanding
Enhanced metal recovery delivers increased metal production, faster drawdown of remaining inventory, and extended value from existing operations. Mining operations gain clearer understanding of solution distribution and recovery pathways, improved evaluation of remaining inventory, and the ability to refine design and economics based on monitored movement, reagent response, and production behavior.

Techniques Supporting Better Leaching
The following methods support enhanced recovery by improving understanding of subsurface conditions and solution movement. These approaches provide complementary insight into flow pathways, distribution patterns, and recovery potential, allowing a more complete evaluation of remaining inventory and opportunities for increased leaching efficiency.
Low-pressure injection direct solution to underleached zones using a well connected directly to a reagent line, typically less than 50 psi.
High-pressure injection uses sophisticated pumps and packers to force solution into isolated zones along a metal well.
We offer a variety of geophysical, hydraulic, and metallurgical monitoring techniques to track the injected solution

Enhanced Recovery FAQs
Get the facts about enhanced metal recovery—how it works, why it matters, and how subsurface characterization supports improved drawdown, reduces bypassed inventory, and increases efficiency in recovery operations.
Enhanced metal recovery is an approach designed to improve access to under-leached zones in a heap leach pad, increase solution contact, and support more complete extraction of remaining metal inventory.
Monitoring helps evaluate solution movement, recovery trends, and fluid migration, allowing adjustments to improve performance and guide optimization efforts.
By improving access to bypassed inventory and enabling stronger production forecasting, it helps protect capital investment and supports more predictable performance outcomes.
It is particularly valuable when standard operations leave remaining inventory behind, when production declines earlier than expected, or before expanding operations.
