Unlocking Lithium Reserves: A Comprehensive Approach to NI 43-101 Compliance for E3 Lithium
Sproule ERCE supported E3 Lithium in advancing its Clearwater project in Alberta by delivering a Pre-Feasibility Study aligned with NI 43-101 standards. The team addressed challenges related to legacy data, evolving development plans, and the unique nature of lithium-in-brine extraction. Through collaborative technical work and detailed geomodelling, Sproule ERCE provided a robust resource and reserve assessment that enabled E3 Lithium to update its Technical Report and strengthen stakeholder confidence.
Project Highlights
- E3 Lithium, a pioneering resource developer in Alberta, needed to prove the viability of their lithium-in-brine assets for a landmark Pre-Feasibility Study (PFS)
- Sproule ERCE applied expertise in petrophysical interpretation, geological mapping, geomodeling, dynamic modeling, and economic analysis to address data limitations
- The team ensured alignment with stringent NI 43-101 standards throughout the assessment process
- This approach enabled E3 Lithium to confidently update its Technical Report to a PFS and advance its Clearwater development project in a competitive lithium market
Challenges:
NI 43-101 Lithium Application: Brine extraction methods differ from traditional mining, resembling oil and gas techniques, creating unique challenges for resource estimation and forecasting under NI 43-101.
Data Vintage and Coverage: Leduc formation reefs were exploited for oil and gas since the 1950s, often with limited data on underlying brines, which are now the primary lithium targets.
Evolving Development Plan: E3 balanced declining lithium concentrations, brine reinjection, and high processing costs to maximize economic returns from the asset.
