Arizona Lithium Limited (ASX:AZL) has successfully identified a north trending basin containing targets interpreted to represent potential lithium mineralised brines.at the company’s Lordsburg Lithium Brine Project in the state of New Mexico, USA.
Lordsburg Lithium Brine Project – Geophysics
In consultation with Western Australia-based geophysical consultants, Resource Potentials, the Company completed a passive seismic survey and Titan magnetotelluric electromagnetics to test for potentially lithium mineralised subsurface brines.
Similar geophysical methods have been used with success by Galan Lithium Limited on their Hombre Muerto Project in Argentina1. The passive seismic HVSR survey was completed across the playa on 14, east north-east trending lines, spaced at 250m with stations at intervals of 50m on lines 8 and 9 and 100m intervals on the remaining lines.
Data from all 14 survey lines were gridded to generate a 3D surface and data grid for imaging and contouring, allowing an interpretation of an elongated sediment filled graben (valley).
A deepening of the acoustic bedrock is observed towards the centre-east part of the survey area, likely the base of the north-north-west trending palaeo-valley bounded by north north-west trending interpreted faults. North-east and north-west trending depressions in the bedrock topography surface (black dashed lines) could represent palaeo-drainage paths/water flows.
“The encouraging results from the recently completed geophysical surveys at the Lordsburg Lithium Brine Project in New Mexico identifying three priority drill hole locations, have provided the company with an outstanding opportunity to progress another project concurrently with the sustainable development of the Big Sandy Lithium Project in Arizona,” Managing Director, Paul Lloyd, said.
“The close proximity to renewable energy sources, direct access to the interstate highway system and sampled lithium mineralisation at surface, have identified this project to have the potential as a timely contributor to growing lithium supply requirements in the USA.”
Based on the results of the geophysical surveys Resource Potentials have proposed three drill holes designed to test geophysical anomalies within the Magnetotelluric Titan (MT) data, as well as local deep anomalies on the acoustic bedrock derived from the passive seismic HVSR survey.
These deep anomalies may relate to potentially lithium mineralised brines.
